Ion Implantation-The Invisible Shield: 1994

Wednesday, April 5th, 2017

There were three organisations collaborating in this European SPRINT project, Imperial College in the UK, AIN in Spain, and
DTI in Denmark. SPRINT was the European commission’s Strategic PRogramme for INnovation and Technology.

This July 1994 video was an introduction to surface treatment of metal tools by the use of Ion Implantation. This technique modifies the tool
surface, improving the wear, corrosion resistance, and frictional properties. The project disseminated knowledge and
applications of Ion Implantation as an effective surface treatment and was targeted mainly at European Small-to-Medium
Enterprises, to improve their productivity and competitiveness in the world market.

It was made in three language versions which were produced for the three SPRINT partners by the Imperial College TV Studio and a fourth version in French, made for I.B.S.  As well as the UK, we went to Denmark and Spain to record the relevant sections of the video. The photo above was taken at DTI in Denmark, you can see me operating camera along with my Imperial academic colleague Tom Tate sitting on the chair on the far right hand side. The video’s voice-over was by Michael Rodd.

Larry Hench: June 1996

Wednesday, June 1st, 2016

gLarry Hench, Emeritus Professor of Ceramic Materials died on 16 December 2015.

He joined Imperial in 1995 from the University of Florida, having made the seminal discovery in 1969 of Bioglass − the first reported synthetic material to form a bond with living tissues.
As Chair in Ceramic Materials at Imperial, he set out to uncover the basic cell biology mechanisms that gives Bioglass its remarkable properties. He set up the Tissue Engineering and Regenerative Medicine Centre with the late Professor Dame Julia Polak. There they made the fascinating discovery that the unique bone henchp2fgrowing properties of the glass were due to the dissolution products of the glass stimulating bone cells at the genetic level. Members of their team went on to make the glass into 3D scaffolds for use in bone regeneration.

The only video footage in our archive is what we shot for inclusion in his inaugural lecture in June 1996. And, unlike other inaugurals that we have recorded clips for, this one actually has him in it.

From the Arithmometer to Electronic Arithmetic – 1998

Friday, May 6th, 2016

On the 29th January 1998 a series of presentations and talks were given during the Chapman/Whitehead memorial meeting. One of these presentations was given by Anne Barrett from the Imperial College Archives. Her presentation was “From the Arithmometer to Electronic Artihmetic – The History until 1955.

Alfred North Whitehead was Professor of Mathematics at Imperial College 1914-1924 and Sydney Chapman was Professor of Mathematics 1924-1946.

Anne also mentions the construction, by college members in the 1950’s, of the Imperial College Computing Engine the ICCE 1.

ILEA Channel 7 Network: 1968-1979

Saturday, November 14th, 2015

ILEA LogoIn the late 1960’s and running through until 1979, the ILEA (Inner London Education Authority) ran and operated it’s own unique analogue cable television network. By the time of its closure it had linked together all of its 1,400 schools & colleges within the London area and also universities, including Imperial. It was Europe’s largest closed circuit television network. The system was installed and operated by the GPO Television Service, but by the time of privatisation and renaming as BT, the network was doomed, with closure looming. We had connection to the cable network in the early 1970’s when the University of London created and operated its own Audio Visual Centre. ILEA Channel 7 Caption Programmes made by the ULAVC were recorded in their own TV studio, based at 11 Bedford Square in central London. Transmissions were all made from videotape by the ILEA TV Studio staff at the Battersea main hub. In the case of programmes made by the ULAVC a separate Channel 7 was operated for their exclusive use. ILEA’s own programmes for schools were on channels 2, 3 and 4.  The ILEA studios and recordings were all to broadcast standard using 2 inch Quadraplex videotape whilst the ULAVC ran on IVC 1 inch videotape. As can be appreciated, all of the programming across the channels was therefore carried out from pre-recorded videotape. But, the network could be run live from any of the three studios at the Battersea main hub. Barry Humphries as Dame Edna Around 1976 I had the brainwave idea to suggest to the ULAVC that we make and provide some programmes from the Imperial studio. The only materials that might be of interest to other universities were perhaps some of the STOIC output which was gaining popularity with the introduction of celebrity interviews with those like film director/actor Mel Brookes and housewife-superstar Dame Edna Everage, otherwise known as actor Barry Humphries, seen in the photo on the left with Mark Caldwell in the Imperial TV studio. Several videotaped programmes were made with the specific idea of being shown on Channel 7 (Terry-Thomas was one), but I then went a step further and suggested we do something live! After I’d consulted with the ULAVC ILEA Battersea Studio 1977 and then the ILEA Battersea operations staff we got a transmission slot and studio access. On 17 February 1977 a pilot programme called London Luncbreak went live on the air from the ILEA Battersea TV studios. The photo on the right shows main presenter James Sinclair during the live transmission. Because of a connection I had with the then BBC “film night” TV series, I managed to get Barry Norman to the studio to take part in the live transmission. Three further programmes were produced in the ‘London Lunchbreak’ series, but our enthusiasm was dashed when we heard that the network was to close in early 1979. ILEA Battersea Control Room 1977 There was little point in continuing when the end was close. We had left it too late to get involved with the network, perhaps a couple of years earlier would have been better and given us a few more transmissions? Over on the left, in the gloom,  you can see me directing one of the live programmes at the ILEA Battersea studios. The videos below are a recording of the pilot London Lunchbreak which includes a sound fault during a film clip! Remember that this programme was totally live from  the ILEA studios. Also, the very last programme made and transmitted over the network by the ILEA, containing a rather large number of old programme titles (jump to the end when you get to that part). The ULAVC never made a farewell programme but continued its videotape operation, but with no cable output. ILEA continued in a similar way until, like the ULAVC, it was totally closed. Both the ULAVC and ILEA had converted into colour production by 1980, however, the now old GPO VHF cable network was only just capable of transmitting high quality colour (it was originally designed for analogue black and white in 1967). So perhaps it would have been difficult to continue with a poor technical service? However, I managed to capture a rare c1978 test transmission from ILEA in colour. It was made on Channel 2 and I was told that the ULAVC loaned ILEA a colour camera to make the live test, which seemed to work as far as I can see, that’s the last video.

Oh, and then there was Westminster Cable TV and another opportunity for live TV, but this time from Imperial College’s own TV Studio; but that’s yet another story, so far untold…

Parallel Computing Research Centre Royal Opening – May 1994

Saturday, August 1st, 2015

An AP1000 Super Computer was donated by Fujitsu Labs to Imperial College to inaugurate the Imperial College/Fujitsu Parallel Computing Centre, opened by HRH Princess Anne in May 1994. It had been in continuous use since then and achieved remarkable longevity for an experimental parallel machine. AP1000The facility had been funded by a partnership between Fujitsu, the EPSRC (Engineering and Physical Sciences Research Council), the Higher Education Funding Council and the Office of Science and Technology. The award on the UK side amounted to £1.65M. This was backed by a significant contribution from Fujitsu, continuing a fruitful collaboration between Imperial College and Fujitsu.

In 1997 Imperial College based a new campus-wide service on an 80 node Fujitsu AP3000 parallel computer, which was linked to the Fujitsu VX vector system, a resource amongst the most powerful in the UK. The systems provided a theoretical aggregate peak performance of nearly 50 Gflops with 15 Gbytes of memory and more than 400 Gbytes of high speed disc storage. With the way technology moves, I suspect that’s all a bit ‘last century’ by now (which if course it is).

In the year 2000 the following announcement was made:

fujitsu“Shigeru Sato, President of Fujitsu Laboratories of Japan, visited the department of computing on 15 March 2000, to give a seminar and switch off the Fujitsu AP1000 in the Imperial College Fujitsu Parallel Computing Centre. Mr Sato’s talk was followed by the ceremony to switch off (seen on right) the AP1000 with the rector, Lord Oxburgh. The AP1000 pioneered much work in parallel applications (CFD, artificial life, visualisation, environmental modelling) and parallel methods research (Parallel Software Technology, Performance Modelling, data mining, optimisation). The machine was still in active use prior to its decommissioning and the groups using it will be transferred to newer machines”

I made this video to commemorate and archive this important event both for Imperial and Fujitsu.  Once again the commentary is by Michael Rodd.

Reactor Centre opening: 22 June 1965

Monday, June 22nd, 2015

1965_Reactor--tojpeg_1417970787838_x2It’s 50 years since the official opening of the University of London Reactor Centre housed at Imperial’s Silwood Park campus. Silwood Park is located about 25 miles West of Central London, near the village of Sunninghill, Ascot, Berkshire. On 22nd June 1965 the official opening took place with the Principal of the University of London, along with the Imperial College’s Rector Sir Patrick Linstead, Pro Rector Sir Owen Saunders and Chairman Lord Sherfield. In 2011 the process application to decommission the ‘GEC 100kW Consort’ reactor was started and is being continued today. Sadly, although the archive has BBC Footage shot at the 1965 opening ceremony, it’s minus the sound track, so P.HSN Reactor Under Construction. From above. Spring 1964the on-screen presentation and interviews mean very little. That’s rather a disappointment as it captures a key part in the college’s history. The photo on the right is during construction. What I do have is a segment from the 1982 documentary that I made about Silwood Park and fortunately we shot a section about the reactor and its operation. Tracy Poole spoke with Dr McMahan a lecturer in Physics about the operation of the reactor centre. We shot inside the main reactor hall, control room and experiments lab. I’m so glad we did this because it will be the only archive material shot about the reactor before it eventually disappears for good. 1135902Because it’s a ‘pool type’ water cooled and water moderated reactor it’s possible to open the reactor up and seen inside the core (yes it’s true). Then you will see a bright blue glow caused by the Cherenkov radiation. The image on the left show this glow which I witnessed myself when I took the shots for the video whilst standing on top of the reactor. When we made this video the reactor centre was still relatively new and only 17 years old, now it’s celebrating 50 years! As indeed I do myself, later this year, with 50 years of working at (and since early retirement, occasionally with) Imperial College!

Below is the documentary extract about the reactor centre and also some lovely aerial helicopter footage we had shot, which shows the beautiful Silwood Park campus.
