Creating this blog is a sticky business!

2 September 2010

Since the start of this archive blog people have asked me various things about the videotape collection. Questions range from: when did the collection start; how many tapes are there; and what formats of tape do you have. So, I thought that just for once I’d write an entry without an actual video in it. Some questions I’ve been asked are answered in the “about this video archive blog’, but I’ll go through them again anyway.

Some of the 700+ tapes in the video archive

The earliest videotape (one inch ‘A’ format) dates from about June 1970 and is on our original videotape format made by the American company Ampex. This company invented the world’s first commercial videotape format back in the mid 1950’s (2 inch Quadruplex). So, our oldest tape was made only 15 years after the invention of videorecording itself. Sadly, playing these tapes back is slowly becoming a problem. Equipment is no longer accessible on campus to run some of the formats we have, but it is possible to use commercial facilities (at a cost). Recently, the earliest collection from the student TV service (STOIC) came under our access.

The Ampex one inch open spool 'A' format tape — Ampex ‘A’ format tapes have gone sticky

I’d forgotten just how many of the original one inch videotapes they still had. There are gems yet to be seen, dating from the early 1970’s through to about 1980, in fact their collection now has more one inch tapes than we do (many of ours are long gone). Anything of importance was transferred to another (the latest at the time) videotape format, but some items (mainly STOIC’s) remain, frozen in time, awaiting that day of playback once more when finances allows us to transfer them into a new digital format.

Playing these early tapes back has recently become a problem anyway. There is an effect called Sticky Shed Syndrome which means that the binder, which sticks the oxide onto the plastic tape, is breaking down. What appears to be happening is that the binder is taking in moisture and going sticky. It’s SO sticky in fact that when tapes are run, the oxide and binder come off the plastic tape and stick to all parts of the videorecorder that the tapes run past. After only a few moments of playback there will be a very loud screeching noise followed by the video head clogging and the machine grinding to a halt. If you put your finger onto the guides inside the machine it will be sticky and covered in tape oxide and a sticky goo.

Oxide is badly shedding from magnetic tapes — Oxide is shedding from magnetic tapes

In the recent blog entry called “seen and gone” I found some old audio recordings of the soundtracks of erased videotapes. These audio tapes also suffered the same problem of shedding oxide. When I started to play them the oxide came off the plastic, as you can seen in the photo. My fingers can be seen through the plastic tape. The one good thing was that whilst running the tapes through the recorder I was also copying it onto computer to then go onto disc.

The U-matic videotape format suffers too

These playback problems have happened because some tape manufacturers got various chemical mixing formulas wrong. It was only in the mid 90’s or so that the problem was fully appreciated. There is only one way around the problems of playback. The tapes, audio and video, have to be baked. That is, the tapes have to be heat treated at something like ±50 oC for a few hours or more. This draws the moisture out, allowing immediate playback to get the material onto another modern format. The temperature used is critical, too high and the ‘Curie point’ can be reached and the tapes automatically erased, or at least the magnetic properties will be lost and thus the recording data will be gone for ever. So there are problems and dangers anyway with this method of recovery!

The various tape formats we have to work with sitting on the edit suite desk

We are therefore faced with a slight problem of playback, even with tapes still in use today like the U-matic system. Most of the tapes seen on the shelves in the top photo are of this format and many are causing playback problems. I’ll be experimenting with heat treatment soon to sample a few tapes for transfer. In most cases I’ll put these onto DVD, assuming they’ll play back okay after treatment. Today, we have many tapes formats as can be seen in this last photo. We’ve gone through: One inch open spool both low and high band; U-matic low and high band; Betacam and now DVCam. Also we’ve encountered half inch open spool, Philips cassette, VHS and so on. With some 700 tapes now being held in the collection, the question is how long will we be able to play back any of the many formats of videotapes that we have?

Seen and Gone: Two

Colin Grimshaw

15 August 2010

So now we come to the second Seen and Gone and this is when we get to see something interesting (and yes I do mean see). In December 1971 STOIC showed their Christmas edition of the then regular news programme Topic. I’ll try to recall the background to this programme if my memory serves me well!

Although by this time we had two videotape recorders in the studio, the programme was shown live to the JCR (Junior Common room), whilst the recorders were used to replay some inserts into the programme (maybe one did also record I can’t remember). At this time it was still not possible to easily record items outside of the studio so some cunning ideas came into use. To enable STOIC to capture external events an 8mm cine camera was used. The footage was then edited together and a simple background audio track of, for example, street noise, was created to play in the background. These inserts were then run into the live programme whilst one of the presenters did a voiceover. In later years a magnetic sound stripe was added to the film to allow sound to be pre-recorded in synch. Things didn’t always go to plan however, the splices in the film sometimes broke during projection or whilst being made ready to be shown. On one occasion a splice broke on the film that was going onto the take-up reel, the easiest thing to do at the time was to ignore it and therefore the film simply spooled directly onto the control room floor in a large pile. This edition of Topic was a good example of where things could and did go wrong. You’ll hear two situations where something happened and the presenter is called on the phone from the control and asked to ‘pad’ until it’s resolved. I thought it was fun if I left those in what you’ll be hearing.

Now, I have called this Seen and Gone, but that’s not strictly true in this case. When I found the audio recording I remembered several spools of 8mm film. These are the original films used to insert into the programmes until portable video became available. They have sat there for 40 years waiting to be seen again. However the videos which they appeared in have long gone. But, in this case I had the soundtrack! So, what you are about to see is the recreation of a lost programme from 40 years ago. I remembered too that I had some photos of STOIC setting up and using the studio at Christmas…..bingo, it was THE same programme I had on audio. So, I’ve been able to use them and the 8mm films to insert at the appropriate places. There does appear to be one film missing and you’ll only hear the commentary and background sound effects. I discovered photos of Lord Penney being interviewed and those too are from the same programme.

So, you’ll be hearing and/or seeing: Guilds Motor club A-Z rally; NUS day of action; Silly Football in Hyde Park; Morphy Day rowing, the London to Brighton vintage car rally and the Lord Mayor’s Show. An interview with Lord Penney (then Rector) was prerecorded and I used the three photos taken at the time of that. Former Union President Piers Corbyn is included and I found a photo taken of that as well. And there’s an added bonus too. Many of the 8mm films were shot with normal Kodak 8mm film stock, so for the first time ever these will be seen in colour. Other items were shot using black and white film. So here is my recreated Christmas Topic from December 1971 with mistakes and technical breakdowns left in.

Seen and Gone: One

The one big disadvantage with videotape is that it can be erased. All too often a recording is considered of no further use and the tape is either thrown away or erased and re-used. But back in the early 1960’s and 1970’s it was cost that was the concerning factor. I recall that the first open reels of Ampex one-inch tape that we used cost around £30 each at that time, something more like £300 in today’s money. So, there was a desire to save money and therefore reuse old tapes again. Recently, I remembered that I had some audio tapes that I’d made from the sound tracks of various programmes and that these programmes had long since been erased. So, I collected them all together and took out one of my faithful old reel-to-reel tape recorders sitting at home. What did I have and was there anything of interest? Well yes, very much so, it turns out. I had a few sound tracks of videos made with the student TV service STOIC for example. Always a good source of college history I listened to what the content was and to whether there might be a gem or two. On a live Christmas 1971 edition of their first news magazine programme TOPIC, I found interviews with Lord Penney (then Rector) about the recent 1971 NUS “Day of action”. This now takes the number of recordings we have of him from 4 to 5 and will be placed into the college archives. We’ll be seeing that programme, in ‘recreated’ form, in the next Seen and Gone number 2.

I also found a soundtrack to a series of programmes I made with Sinclair Goodlad. One of these programmes, which is a May 1972 interview with the very first student counsellor, still exists on the original one-inch videotape, although it has never been transferred to any modern format so at present we’re unable see it. The photo of Sinclair is from 1967 and was taken during one of his “20 minute talk” sessions he ran on Wednesday afternoons in Electrical Engineering. Behind him can be seen our very first videotape recorder, an enormous machine made by Philips and full of very hot valves.

A nice piece of timing in my discoveries was an interview with Lord and Lady Flowers. This was recorded after one of their famous Beer and Bangers parties held in their flat at 170 Queen’s Gate. On the 20th October 1976 James Sinclair from STOIC went along with the portable videorecorder kit to ask a few questions about why the event takes place. It’s a pity that no photos were taken at the time.

Felix is the student union newspaper with its first edition dating from December 1949. The editor at the time of this next interview was Clive Dewey. There is mention of a colour edition and I think he was the first editor to achieve this. I recall Clive doing some things with STOIC as did another former Felix editor Mike Williams. Again James Sinclair is the interviewer in this 7th October 1976 recording.

Next time you’ll get to hear, (or is that see?) the 1971 Christmas edition of Topic, with some special surprises after 40 years of being lost….

Rectors: Lord Brian Flowers

Colin Grimshaw

28 June 2010

Brian Flowers (1924-2010) became Rector in succession to Lord Penney in 1973. Then Sir Brian, he quickly became popular and approachable with staff and students alike. The now famous ‘beer and bangers’ parties held by him and Lady Mary Flowers (1921-2016) were hosted in their flat at the Norman Shaw designed building at 170 Queens Gate. This gave many people the opportunity to meet both of them and in particular to gain access to one of the most wonderful buildings owned by Imperial College. Five years after he became Rector, I shot a video with the student TV service STOIC, this was the first time a video had been shot in 170 and in particular up in the Rector’s flat (a photo taken during this event is at the bottom of this entry with me in silhouette on the extreme left hand side).

Although you’ll find a version of this first video posted on other Imperial pages I think it’s important to repeat it here and set it in context. Also, this is the full version which includes an interview with Lady Flowers. At that time, what eventually became the ‘family room’, was then the music room with a grand piano occupying most of the space. I thought it might be fun to ask him to sit at the piano for the first part of the recording which was about him, his work and what the Rector of Imperial did on a day to day basis. As always he happily agreed and so that it what you’ll see first. Because Mary Flowers was so much part of his life at Imperial, the second part was shot in the Sitting Room with them both talking about their “Imperial life”.

As always, I’m including something that has only recently been re-discovered. On the 20th January 1984 STOIC recorded a studio interview with Brian Flowers who, by then was Lord Flowers of Queen’s Gate. Unlike other interview with him, he not only talks about his work as Rector, but as the then Chairman of the CVCP (Committee of Vice-Chancellors and Principals). He also touches on obtaining his MA at Cambridge, being a visiting professor at MIT in the USA and his earlier job at the Atomic Energy Research Establishment. Also discussed was something that was new at that time, Imperial College spin-out companies.

Finally, the last video shot with both Brian and Mary Flowers. For the 2007 centenary I had proposed a series of videos with all living Rectors. And we all felt it appropriate that we should interview both Brian and Mary Flowers at what was, their home for 12 years, 170 Queen’s Gate. In this extract, they discuss having a good working and social relationship with the student body and what was their most memorable event in the college calendar, the beer and bangers evenings. Here they are in the Council Room in 170 Queen’s Gate.

Recording in the sitting room of the Rector's flat at 170 Queen's Gate in 1978 — 1978 recording in the sitting room of the Rector’s flat at 170 Queen’s Gate

I’d been a regular visitor to 170 during their 12 years at Imperial. On one occasion Mary had persuaded me to provide and run some background music for her fund raising fashion show event for the day nursery, as mentioned in the last video. Nothing too ordinary was this event though, as we had Princess Anne attending…and without warning Mary suddenly insisted I was introduced, sadly no photo was taken. My last meeting with Brian Flowers was 2 years ago when Mary asked me if I could call in and see them, because she wanted to ask me a favour. They were, by now, living in north London and so I called in one lunchtime and had the most hospitable lunch with them sitting around the kitchen table and chatting about Imperial and all the latest news (and gossip too). And that takes me back to the kitchen at 170 and the many times Mary insisted on making me a cup of tea, if I were ever there, for some reason or another…..

Nobel Laureates

Colin Grimshaw

9 June 2010

One area where the archives are sadly lacking in both audio and videos recordings is on the subject of Imperial’s Nobel Laureates. And, as always, my appeal is to anyone who may have something to boost our collection, in either audio/video/film and so one. This current entry will focus on those Nobel Prize winners for whom we have recordings.

In 1948 Dennis Gabor (1900-1979) joined Imperial College as Reader in Electron Physics, he was appointed FRS in 1956 and Professor of Applied Electron Physics in 1958, retiring from the Chair to become Professor Emeritus and Research Fellow in 1967. His experiments on holography began in the 1940’s and on the flat television tube in the 1950’s. The model for his flat TV tube is held by the college archives. I met him only once when he was in our TV Studio to watch a film. On leaving, he spoke to me about the Sony colour TV we had. He said “Ah you have a Sony colour television” to which my reply was along the lines that the Japanese were very clever with their technology. He put his hand on my shoulder and told me that the principle of its workings (the TV’s single electron gun cathode ray tube) was something that he had proposed and suggested, but for which funding could not be found at that time and that the idea went to Japan and was used in those Sony televisions.

For the Invention of Holography, Gabor was awarded the Nobel Prize for Physics in 1971. A few months later on 22 February 1972 Gabor repeated his Nobel lecture, but this time for a special audience at Imperial. For us we are fortunate that a sound recording was made of the event. It’s not amazing quality, but I’ve done what I can with the sound to help improve it and also slowed down the tape that was clearly running too fast when I played it back. It’s introduced by the Rector at the time Lord Penney and there’s a vote of thanks by a departmental colleague, Professor Colin Cherry. That itself is interesting as the only sound recording we currently have of Cherry speaking at Imperial ++. Even more interesting are the references by both Penney and Gabor to power cuts. This was because of the 1972 Miner’s Strike and the so called “three day week”. Imperial, like all other places was subject to limited mains power during the day and at specified times the entire campus would be plunged into darkness….even Nobel Prize winners!

In 1981 I made a promotional video for the department of chemistry. A section within the video included one of the current students talking to Professor Sir Geoffrey Wilkinson (1921-1996) in the office. At the time, Wilkinson was head of department. It’s a pity that this is such a general video and that we never recorded anything more in-depth with him. I’ve been able to go back to the original ‘rushes’ (that is the original videotape shot at the time) of this interview to improve quality slightly, but it was made 30 years ago on our original low-band U-matic colour recording system (a single-striped faced, vidicon tube camera).

The only other recording of him was made in February 1992. this was for a video called “Snapshots”. The video brought together some of the current research being carried out at Imperial and showcased it for, primarily, an external audience. This sequence however is very short indeed and is the only record we have of Geoffrey Wilkinson in his research lad. And, for what ever reason, I don’t seem to have the original rushes any more so can’t see if there was anything else recorded at the time.

Finally we take a look at Professor Lord George Porter (1920-2002). He became chairman of the Centre for Photomolecular Sciences (and Professor of Photochemistry) at Imperial in 1987. He received a Nobel Prize in Chemistry in 1967. He was a former Director of the Royal Institution (1966-1985) and this was when I first met him. That was during the 1966 televising of the Christmas Lectures with Eric Laithwaite (see Laithwaite blog entry). This first recording is fun because we recorded it in his lab in the basement of the Beit Building. It’s full of lasers, for which I’m sure he should have been wearing safety glasses.

George Porter A 2/8/1995 — George Porter’s 1995 Singapore lecture with Martin Sayers on cameras

Lastly, a unique recording of Lord Porter. This was not actually a planned videotaped lecture as such. In August 1995 he was asked to give the 10th Lee Kuan Yew lecture in Singapore. As he was unable to attend in person it was suggested he gave the talk via a videoconference link. We re-arranaged our TV studio to allow it to link into our videoconference system. You may spot him looking down at a monitor which was showing him the audience in Singapore and at one point talking to Martin Sayers behind the camera to confirm timings. He was very easy to work with and like Eric Laithewaite skilled in presenting on TV and film.

Prior to the day, he telephoned me several times to discuss details. He had a habit (so I was told) of sitting in his garden in summer months and making calls on a cordless phone. However, he was always at the limit of range of the base unit and was barely audible, so the call was full of hiss and crackle. It was only by chance that I happened to put a videotape into a recorder to make a record of the event and I’m glad I did. So here is the lecture, given live to Singapore, on a very hot London day on 2 August 1995. And because it was so hot, we left the usually noisy air-con unit switched on and you may hear that in the background.

Departments: Electrical and Electronic Engineering

Electrical Engineering 1962 — Electrical Engineering in 1962

It’s not until you start to look at individual tapes in our archive that you realise how many different videos have, or could have, a link between them. In this latest blog I’ve found an example of that with two research videos made for the Electrical and Electronic Engineering Department ( Electrical Engineering Department as it was when these were made). We’ll also be seeing something of the actual department from the past. I should also point out that until 1976 were part of that department (a departmental facility) and as such located within the building. Our first location was on the 3rd floor moving to the main walkway level 2, where many of you may remember us.

In February 1981 Professor J.C Anderson (“Andy” Anderson 1922-2001) asked me to make a video showcasing the research in his Electrical Materials section within the department. I can’t recall the exact reason why we made the video, but am assuming it was to do with an open day, or similar, for Postgraduate research students, hence his references to getting PhD’s at the end of the video. The research going on at that time is shown and he makes reference to the work by Mino Green on Electrochromic Displays, but more on that in a moment.

Andy was very keen on the use of modern technologies for teaching, research and promotion and was the Chairman of the “Educational Technology Committee” (long since disbanded). It was his idea that I should be the only non-academic (although I was on the ‘academic related staff’) member of that committee to be able to update and advise on matters relating to the use of video within Imperial. He was not afraid to appear in front of the camera or, as in this case, record a voice-over as well. So here is the video we made with him: “Electrical Materials Research at Imperial College”

In the previous video, mention was made of the work by Professor Mino Green (1927-2022) (then Dr) on Electrochromic Displays. This work was already being carried out at the time of the previous recording. In fact the first video on Electrochromic Displays was made a year earlier in April 1980. We made some 7 videos on the subject with the last being in March 1993. I gather that Professor Green’s work has now moved away from such devices, but the concept was interesting and novel. The video itself is an example of how to show large numbers of people the research work being carried out by a small dedicated group. Even as long ago as 1980 we were having copies made into the American NTSC TV system to enable research work to be showcased in the USA, Mino Green’s was an example of this. Here is the video from 1993 on “Electrochromic Displays and Windows”.

Mino was an Emeritus Professor of the Science of Electrical Devices. His webpage described his work as “…The interplay of solid state physics and chemistry, particularly physical chemistry, has been an abiding interest. This has led through many areas, including semiconductor electrochemistry, chem- and physi-sorption on semiconductors, thermoelectric systems, solid state photo-and e-beam-decomposition, and transition metal oxide electrochromic systems. Now my main interests are in the larger end of nano-systems…”. In 1980 STOIC recorded an interview with Mino where he explains his area of research, you can see that video above.

Ampex Video Recorders in use in TV Studio number 2

Finally for this particular blog I’ve pulled something out of the archive from 1978 and you’ll see that in just a moment. It was a video made to showcase the whole department rather than a particular division or research project. Again, I can’t recall the exact reason why we were asked to make the video, but assume it was either an open day or event with alumni for example. Open day is more likely as the video is dated June 1978. It was a major task to make too, as editing was primitive on our old Ampex open spool one-inch tape machines. Nothing was automatic and edit points were marked with white (‘chinagraph’) wax pencils onto the tapes directly, spooled back and then run up to speed for editing. Recently I re-discovered a tape, made in 1974, where we are showing what the studio could do. So, before we see that 1978 video, here I am in our original TV Studio number 1, showing briefly the Ampex recorder in use, which I can assure you was as heavy as it looked!

At this time, we had no real means to record outside of the studio. One option though was to link from a location back to the studio by cable. And, because we were located in the Electrical Engineering, the whole building had video cables running from the ground, to top floors. We then had the ability to run from a location point on each main floor, down to the studio and potentially elsewhere. In the end, cables were available to and from many different buildings around the South Kensington campus. However, by this time we had already gained the ability to record outside of the studio having just moved into colour operation on the U-matic tape format. Portable battery operation was then made possible. The video that follows is an example of this.

So back then to the video I made for Electrical Engineering . The video did require a voice-over, but could I get anyone to volunteer to record it for me? Well the answer was no and being at a stage of needing to start the editing I had to do it myself. That aside, the video is a unique record of the department showing its teaching and facilities. I was asked to make specific reference to the fact that every lecture room was equipped with an ‘overhead projector’, how times have changed! The department also had its own glassblower, electronics servicing and draftsman. Here then is a snapshot (in black and white) of the department as it was in the early summer of 1978.

Tywarnhale Mine, Cornwall, April 1980

Colin Grimshaw

26 April 2010

It’s funny how things happen by chance. This months entry is a bit like that. I thought it was about time I made use of some of the footage that we have of the college’s Tywarnhale mine in Cornwall, when I looked at the label on the tapes I noticed that it was 30 years ago this month, April 1980 that I went down to Cormwall. The mine and surrounding land (purchased in 1909/11 with extra land purchased in 1912) was sold by Imperial in about 2005. Here’s a BBC Cornwall web page about the sale dated 15th October 2005. As we couldn’t find any real photos of it in the college’s archives, the picture of the RSM sign is from one of the videotapes I shot. Here’s a brief history of the mine from the “Cornwall Calling” website. Please click on MORE to continue..

Camerawork at the old tin mine at Tywarnhale in Cornwall — Colin on camera at the college’s mine at Tywarnhale, Cornwall in April 1980

The videos you’ll see were all shot about 9 months after we received our new colour portable recording equipment. This all sounds amazing, but the early equipment was not a camcorder like the ones used now. It was a camera connected to a stand-alone videorecorder, and that was a heavy piece of kit and so was the camera. The entire unit ran from what are called sealed lead acid batteries and were the main cause of it all being so heavy (a bit like a car battery but smaller). To make matters worse, these batteries were in both the camera and recorder. If you look at the photo you’ll see a small black box at the back of the camera containing one of these batteries.

Shooting video underground was a new experience for me and former colleague Stephen Bell who come back to help me out for the few days we were down in Cornwall. We needed to hire battery lighting and create a way to protect the equipment (which of course was brand new) from the various elements we faced: water dripping down, heat and of main concern, humidity. A way was found to wrap equipment in polythene, but allow a way to operate it without unwrapping it! We found dry areas to park the recorder and run out an extension camera cable to where I was located. In most cases the cable ran in deep water from point a to point b and this photo gives an idea of what we took with us and how it connected together.

Steve Bell takes turn to operate the camera — Steve Bell takes turn to operate camera high up on the misty mine hillside

When speaking with Steve about this blog he mentioned that this was the first time he’d ever seen the ‘humidity’ light illuminate on a videorecorder. Indeed this happened several times when underground and, because of moisture, we had to remove videotape that was stuck to the video head drum. Needless to say, these tapes were then useless, so we lost a good few recordings. It’s also rather difficult trying to take the lid off of a video recorder when you’re underground and trying to see what you’re doing with a miner’s lamp on your helmet being the only source of light! Jumping forward to this year, 2010, it’s been a struggle with some of the U-matic tapes making them playback correctly. Time has not been too kind to them and all the problems underground didn’t help (moisture). But, they’re all now backed-up onto DVD from where these clips have now come.

This first video sequence is taken from the car being driven by Steve. I’m hanging out of the car window with a very large and heavy camera. You’ll also notice that this, and all other shots, will look a bit ‘soft’ and almost ghostly. This is because our very early colour camera had what is called a Vidicon tube inside it. These camera tubes required large amounts of light to get good pictures. As you’ll see, the weather was not brilliant and was very misty. None of this helped the situation. Thus the shots are rubbish compared to material shot these days. This video shows the original college buildings along the entire site.

This next video shows: students walking along the road along side the mine; Dr Thomas explaining how to use various instruments; a student entering the mine via ladder down the vertical shaft and two sequences showing students working underground. Now, it’s worth remembering that Steve and I had to enter via this same entrance carrying all of our equipment. We did have help, but camera, recorder, tripod, lights and spare batteries & tapes are difficult to carry when going down a vertical ladder! And, of course we were kitted out with the same outfits with: boot; helmet and safety lights etc. We all came out at the end, more than a bit dirty and very wet indeed.

Tywarnhale Mine area map (early 1900's) — Tywarnhale Mine area map (c1920?)

The original 1911 purchase document says that the purchase was to “…enable the Professors and Students of the college , including the Royal School of Mines, to use the levels, above adit level, of the South Towan Mine in the manor of Tywarnhaile…” There are two interesting things I’ve spotted in searching for this information, one is the spelling of Tywarnhale. I’ve found three versions: Tywarnhale, Tywarnhaile and Tywarnhayle. But I’ve gone with the version as seen in the photo of the sign that was outside the main building. Also, in the original document it’s referred to as South Towan Mine not Tywarnhale. If you know any more on this matter we’d love to know so we can get the history correct.

Tywarnhale Mine c1950's — Tywarnhale Mine c1950’s/60”s

There are very few photos of the mine in the college archive, so, if you have any that you would like to donate or would allow to be copied, then Anne Barrett, of the College Archives, would love to hear from you. And, as always it’s thanks to her for sourcing the material that we do have available. It’s very lucky that the video footage was shot and that we have at least some record of our former students working in it. If YOU are one of those shown in the videos then please do comment, we’d love to hear from you. It’s been interesting to run through all these tapes again after these 30 years and remembering all the major technical issues we had to overcome. But not too pleasant remembering how wet it was underground and how the weather was typically UK that week. These recordings are a perfect example of what archiving is all about, remembering our past and our history. The fact that this ‘outpost’ was part of Imperial College from 1911 until about 2005 is something that most people are simply unaware of.

Oh and one last thought….I thought it was an old Tin mine, but all other references seem to say that it was Copper…..30 years have certainly confused me!

In 2016 Michael Hulmes added this useful comment to the blog post:

The guy swinging on the rope, in white overalls and blue undershirt in the underground video is Geoff Perry. I suspect his colleague with his back to the camera is Paul Dayton-Lewis. The red haired guy in the video being instructed by Dr Thomas is Philip Sharman. All were in the Mining Engineering class which spent six weeks at Tywarnhale through easter 1980

Queen’s Tower

Colin Grimshaw

6 April 2010

One day, back in 1988, someone asked me the question “Could you do live TV from the top of the Queen’s Tower?”. Up to that point I can’t say I’d really thought about it much, but it was an interesting question nevertheless. But we’ll come back to that in a while.

Anyone who has visited the South Kensington campus would have seen the tower at some point. It’s some 287 feet tall and has some 324 steps up to the dome area. One of the main times the tower is noticed is when the bells are rung and these are as follows:

Queen’s Accession: 6 February
Queen’s Birthday: 21 April
Queen’s Coronation: 2 June
Duke of Edinburgh’s Birthday: 10 June
The Princess Royal’s Birthday: 15 August
Prince of Wales’ Birthday: 14 November
Queen’s Wedding Day: 20 November
and of course both PG Awards and Commemoration Days each year.

It was on 20 November 1997 that we recorded the bell ringers for the first time. This was to mark the Queen’s 50th wedding anniversary and a special ring was performed. Carrying cameras and recorders up the tower is not an easy tasks as the spiral staircase was never designed for this. But we made it and proceeded to capture the event. What no-one had bothered to tell us was that the tower does move a bit when the bells are being run. First one way and then the other depending on which set of bells are being run at the time. Sets of bells are hung in different ways; one set ‘left to right’ and the other set ‘top to bottom’. This therefore gives a strange effect of movement swaying one way, then the other. The combined result when all the bells are being run is a very odd circular motion. Although I’ve recorded the actual bells with hanging a mic in the bell chamber, I’ve never captured them on video…but someone else has! If you go to this YouTube video you’ll see the horrifying sight of the whole set of bells ringing below the camera lens. I can’t say that it looks very safe up there and the volume of sound must be rather high too.

Another great reason to remember the Queen’s Tower were the (now long gone) performances in May each year of the 1812 overture. These were accompanied by live explosions provided by DramSoc and the bells in the tower were rung. I’m not certain why this event stopped, maybe it was the British weather! Anyway, in May 1979 I recorded the event in colour, the same summer that we actually got our colour equipment.

And so, back to the start and that question about live TV from the top of the tower. Back in 1988 during preparations for one of the first Alumni weekends the idea came about to broadcast the weather one morning from the Queen’s Tower. Francis Wilson was, at the time, forecasting the weather for the BBC Breakfast programme. Because he’s an Alumni of Imperial he was asked if he would do it and of course he agreed.

We did weather from the tower twice and you’ll notice the reference to hearing the sound this time around. In fact we were some minutes away from the live link and someone managed to move the equipment providing the ‘line of sight’ link. You can see some photos I took at the time and two of these show the amount of equipment we had to carry up the tower. One is showing the equipment set up for controlling sound and vision and the other is showing the infra-red line of sight link from the tower down to the area now known as the “tower rooms”. One thing we were lucky to have was mains power and down in the bell ringing chamber, a telephone line.

Alumus-Day-1988-InfraRed-downlink — Infra-Red downlink from tower to ground floor

The recording you’re now able to see of the event was made down on the ground floor where the TV monitors were located. I’m still amazed it actually worked and the quality was pretty good too. The infra-red link had to be lined up with a telescope that had a cross-hair to align with the receiver, also set up on a tripod down on the ground. All you then had to do was to feed video and audio into the unit and you were in business. The only problem, as we discovered, was not knowing IF those down below could actually see and hear anything once you had started the event.

My colleague at the time Chris Roberts is seen operating the camera whilst I was pressing the buttons, mixing sound and running-in the videotaped sequences we were given from our colleagues in Physics. It was good fun, the Alumni visiting seemed to enjoy it, but it was very hard work indeed….there are a lot of steps up to the top and I was a lot younger then too!

The day before the event we had already taken most of the equipment up the tower and tried out the link. Those down on the ground floor were somewhat surprised to see this caption on the TV screens. It was broadcast from the tower and was announcing the forthcoming live link the following morning.

Promotion: 1 – Imperial College

Colin Grimshaw

17 March 2010

In one way or another, ever since we’ve had the use of video as a medium we have used it to promote things. You will have already seen in other posts the promotion of specific research projects or research groups and so on. But we’re going to start another series that shows how we’ve tried to promote the college as a whole. I’ll also mention that we’ll see how individual departments have tried this too, examples being: Chemistry, Civil Engineering and the Management School (now Business School), so watch out for those blog entries coming sometime soon.

To coincide with the 1985 centenary of the City and Guilds College an impressive exhibition was put on in the Junior Common Room in the Sherfield Building. Although this was primarily research work, schools were invited and special lectures and tours were held, Therefore, very large numbers of school children were going to visit the college and there was, of course, huge possibilities for student recruitment. So, two promotional videos were (initially) commissioned to promote the college to school children and to potential postgraduates. This was also the first time that moving aerial footage was taken of both the South Kensington and Silwood campuses. The only unfortunate thing was that the footage was shot in January and we’d just had a downfall of snow, so the campuses don’t look too inviting!

The undergraduate promotion video was called “Studying for the Future” and shows all of the usual things to excite potential undergrads. Once again, the nice thing about this and the other videos, is the wonderful record of college life. Also, the campus as it then was, is recorded with the current students and staff going about their daily lives. I wonder how many alumni might actually spot themselves in some of the shots?

A second video was made at the same time. This was to show the research work and activies going on at Imperial and was entitled “Discovering the Future”. I hope you’ve spotted the trend with these titles of the videos all following a certain style with the “….the Future”? A large proportion of this second video was also seen in the video made for undergraduates. The theme used was of a ‘research file’ concept and when you see the video you’ll understand what I mean. And, can those former Blue Peter TV programme viewers spot Valerie Singleton doing the voiceover in this second video?

Next time I’ll show you a third video for those considering taking a masters degree. Can you guess what the title might be?

STOIC: Two

Election results live from the Great Hall

Last time, in STOIC One, we looked at the very start of STOIC with clips from things like: an early promotional video to join the club and Morphy Day on the tow path at Putney. Staying with that line of thought, this time we’re going to see an early example of coverage of a rag event, Election Results ‘live’ from the Great Hall and the days when students had a “Mooney” for lunch rather than an sandwich.

Firstly though, the idea for IC Radio started in 1974. In the days prior to the internet, to be able to hear radio, you needed a radio. For a radio to hear your broadcast you needed a transmitter (a legal one too). So, for IC Radio to operate it would need to be able to transmit.

By the time that IC Radio was about to open, there were ways to achieve this ‘within’ a building (as opposed to an actual transmitting aerial as such). As you will hear in the interview, a ‘leaky feeder’ cable was the method used to enable broadcasts on the medium wave. Mark Caldwell (a former STOIC Chairman) and main presenter at the time, interviewed John Allen who became IC Radio Station Manager. This video is from 4 March 1976 and has a few glitches in its playback, but it’s not bad for 35 years of age. John Allen has his own archive website with loads of old photos and sound clips, so you may wish to hop over and read more about it, click here.

Coverage of rag events was a regular and popular item within STOIC’s programme schedule. Whether it was: a simple collection; tiddlywinks down Oxford Street or, as we’re about to see, “Guilds Silly Sports” outside Harrods in Knightsbridge. This was always a good location for all involved, as it’s about 10 minutes from the South Ken campus. So, no one had to travel too far and this was important for STOIC when a rag took place on a Wednesday afternoon – the time in the week when STOIC’s news programme was recorded and edited. So, returning with the videotape to start editing was always the main thought for those waiting back in the studio. This is one of the earliest rags recorded back in 1979. Colin Palmer interviews those taking part and more importantly, those giving money…

Hustings, elections and the UGM, (where the results were announced) were also high on the STOIC list of events to be covered each year. When, in the early 70’s, parts of the college were linked by both video and audio cables an idea came to mind. Why not try and link from the great hall and report the UGM live via STOIC? When the idea was first suggested the technology was not quite in place to allow video as well as sound to be relayed back to the TV studio.

So, in year one, Mark Caldwell presented live segments in sound only, with a photo of him showing in vision! Year two was a lot better and technology allowed a full linking in vision and sound. So, five years on from the first attempt, here’s a clip from the UGM of 1980 with Paul Johnson presenting.

But…this is just a bit different again. Why? Well, because by now STOIC was running its own live programme AND also linking into IC Radio at the same time. You’ll see what I mean in this clip and you’ll hear me on the earphone cue system which was clearly too loud that day! The slight pause before Dave Fuller starts speaking is because they were waiting for a cue from IC Radio to confirm the link-up between the two networks, all rather complicated for those early days.

Finally, if you were a student in the 1960’s to 1980’s you may well remember going for a “Mooney” at lunchtime. What was this? Well the answer is simple. Victor Mooney (Died on December 27th 2012 aged 89) was college Catering Manager from 1953 to his retirement in 1985. He became part of college tradition and so did his food, hence the reference “Mooney”. It’s a bit like saying you’re using a Hoover I guess. Over the years he came in for some serious complaining by the students, but, as he always said, if he was given a serious budget he could provide a serious meal. Here he is from 1979 talking to STOIC regular Dave Ghani.
