Technical Details of the Elliott 152 and 153
Appendix 1 Technical Details of the Elliott 152 and 153 Introduction The Elliott 152 computer was part of the Admiralty’s MRS5 (medium range system 5) naval gunnery project, described in Chap. 2. The Elliott 153 computer, also known as the D/F (direction-finding) computer, was built for GCHQ and the Admiralty as described in Chap. 3. The information in this appendix is intended to supplement the overall descriptions of the machines as given in Chaps. 2 and 3. A1.1 The Elliott 152 Work on the MRS5 contract at Borehamwood began in October 1946 and was essen- tially finished in 1950. Novel target-tracking radar was at the heart of the project, the radar being synchronized to the computer’s clock. In his enthusiasm for perfecting the radar technology, John Coales seems to have spent little time on what we would now call an overall systems design. When Harry Carpenter joined the staff of the Computing Division at Borehamwood on 1 January 1949, he recalls that nobody had yet defined the way in which the control program, running on the 152 computer, would interface with guns and radar. Furthermore, nobody yet appeared to be working on the computational algorithms necessary for three-dimensional trajectory predic- tion. As for the guns that the MRS5 system was intended to control, not even the basic ballistics parameters seemed to be known with any accuracy at Borehamwood [1, 2]. A1.1.1 Communication and Data-Rate The physical separation, between radar in the Borehamwood car park and digital computer in the laboratory, necessitated an interconnecting cable of about 150 m in length. -

The shop stewards of the GECAction Committee, with thei.r staunch allies on the District Commi_ ttee and in the 1ocal offices of the unj.ons concerned., have, in the courageous struggle, won deep admiration all over the country. From the terrific mail which has come to the offices of the Instifute Jor WorkersrControl, we can say without doubt that_sympathy for the proposed action extended throughout the whole country, and into every major industry and trade union. A body like the lnstitute, which exists to co-ordinate research and inlormation services, cannot, of course, offer any sensible advice about how particular actions should be undertaken. -

1/24/2019 Marconi Company - Wikipedia Marconi Company The Marconi Company was a British telecommunications and engineering Marconi Company Ltd company that did business under that name from 1963 to 1987. It was derived from earlier variations in the name and incorporation, spanning a period from Former type Private company its inception in 1897 until 2006, during which time it underwent numerous Industry Telecommunications changes, mergers and acquisitions. The company was founded by the Italian Fate Acquired by GEC inventor Guglielmo Marconi and began as the Wireless Telegraph & (1968) Signal Company. The company was a pioneer of wireless long distance Renamed to GEC- communication and mass media broadcasting, eventually becoming one of the Marconi Ltd UK's most successful manufacturing companies. In 1999, its defence (1987) manufacturing division, Marconi Electronic Systems, merged with British Predecessor Wireless Telegraph Aerospace to form BAE Systems. In 2006, extreme financial difficulties led to & Signal Company the collapse of the remaining company, with the bulk of the business acquired (1897–1900) by the Swedish telecommunications company, Ericsson.

A Historical Perspective of the Development of British Computer Manufacturers with Particular Reference to Staffordshire
A historical perspective of the development of British computer manufacturers with particular reference to Staffordshire John Wilcock School of Computing, Staffordshire University Abstract Beginning in the early years of the 20th Century, the report summarises the activities within the English Electric and ICT groups of computer manufacturers, and their constituent groups and successor companies, culminating with the formation of ICL and its successors STC-ICL and Fujitsu-ICL. Particular reference is made to developments within the county of Staffordshire, and to the influence which these companies have had on the teaching of computing at Staffordshire University and its predecessors. 1. After the second world war In Britain several computer research teams were formed in the late 1940s, which concentrated on computer storage techniques. At the University of Manchester, Williams and Kilburn developed the “Williams Tube Store”, which stored binary numbers as electrostatic charges on the inside face of a cathode ray tube. The Manchester University Mark I, Mark II (Mercury 1954) and Atlas (1960) computers were all built and marketed by Ferranti at West Gorton. At Birkbeck College, University of London, an early form of magnetic storage, the “Birkbeck Drum” was constructed. The pedigree of the computers constructed in Staffordshire begins with the story of the EDSAC first generation machine. At the University of Cambridge binary pulses were stored by ultrasound in 2m long columns of mercury, known as tanks, each tank storing 16 words of 35 bits, taking typically 32ms to circulate. Programmers needed to know not only where their data were stored, but when they were available at the top of the delay lines. -

A/C SERIAL No.WG768 SECTION 2B INDIVIDUAL HISTORY SHORT SB5 WG768 MUSEUM ACCESSION NUMBER 85/A/06 Built as sole example of its type by Short Brothers and Harland at Sydenham, Belfast to specification ER.100, to contract 6/Aircraft/5347/CB.7 (a). This aircraft was used to find the optimum format for the planned English Electric P.1 interceptor, which became the Lightning supersonic fighter. It specifically investigated problems associated with low speed handling characteristics of swept back wings at speeds below 350 knots. Constructor’s number SH.1605. It could fly with different amount of wing sweep, though this could not be changed in flight, and with a conventional ‘T’ tail or low mounted tailplane. Ordered from Shorts as a way of checking the English Electric calculations on the Lightning, English Electric thought the project a wasted effort. 27 Jul 50 Allotted serial number WG768 2 Dec 52 Following delivery from Belfast by sea and road, first flight at A&AEE, Boscombe Down, with 50-degree wing sweep and high set fin-mounted tailplane. Pilot Tom Brooke-Smith. Completed its initial test schedule without incident within seven months, though very underpowered. 29 Jul 53 First flight with new 60 degree sweep wing; the aircraft had earlier been returned to Belfast for alteration of the wing angle by installing this new wing. Aug 53 Flown for first time by English Electric chief test pilot, Roland Beamont, who was in charge of the P.1 flight-testing programme; he felt that the T- tail was unsatisfactory. 5 Sep 53 Made its first public appearance at the S.B.A.C show at Farnborough, flown by Tom Brooke-Smith. -

INDUSTRIAL POLICY in EUROPE SINCE the SECOND WORLD WAR: What Has Been Learnt?
ECIPE OCCASIONAL PAPER • No. 1/2012 INDUSTRIAL POLICY IN EUROPE SINCE THE SECOND WORLD WAR: What Has Been Learnt? By Geoffrey Owen Department of Management, London School of Economics www.ecipe.org [email protected] Rue Belliard 4-6, 1040 Brussels, Belgium Phone +32 (0)2 289 1350 ECIPE OCCASIONAL PAPER EXECUTIVE SUMMARY Prompted by the revival of interest in industrial policy in several European countries, this paper considers what lessons can be learned from earlier European experience. The focus is mainly on sectoral or targeted industrial policy, designed to improve the performance of particular industries. Since the Second World War European industrial policy has passed through two phases. The first, starting in the 1960s, saw a series of attempts by governments, especially those of the UK and France, to create national champions in industries deemed essential to the health of the national economy. Among the favoured sectors were high-technology industries such as aerospace and computers; part of the motivation was to narrow the “technology gap” between Europe and the US. There was also a widely held belief in scale as the key to inter- national competitiveness. With some exceptions these interventions were generally unsuccessful. Policy-makers tend- ed to overrate the risks and costs of market failures and to underestimate those associated with government failures. There was also a mistaken assumption that there were certain technologies which a country somehow needed to have, and that they were more likely to be acquired through centralised direction than through competitive markets. The cost to the taxpayer of ill-judged industrial policy was high.
