Plessey

Founded in 1917 in Marylebone, central London but moving to Cottenham Road in Ilford early in 1919 (and then to Vicarage Lane where it remained) The Plessey Company became one of the largest manufacturers in this field as the radio and television industries grew. Plessey were partners in the development of the Atlas Computer in 1962 and in the development of Digital telephone systems - System X - during the late 1970s.

Royal Observer Corps - Preparation. At the end of September 1938 the crisis which resulted in the Munich Agreement lead to the Corps being called out for a week. This exercise proved to be invaluable as it drew attention to organisational and technical problems and gave time for solutions to be sought. Exercises held throughout 1939 enabled necessary modifications to methods and structure, the Observer Corps would evolve over the coming years, a process aided by the keenness with which Corps members from every walk of life addressed the process. ...

The Marconi Company opened the world's first radio factory in Chelmsford in 1898 and was responsible for some of the most important advances in radio and television. English Electric acquired The Marconi Company in 1946 which complemented its other operations; heavy electrical engineering, aircraft and its railway traction business. In 1968 English Electric was subject to a takeover bid by the Plessey Company but chose instead to accept an offer from GEC. The Marconi Company continued as the primary defence subsidiary of GEC, GEC-Marc ...

The Aircraft and Shipbuilding Industries Act 1977 saw Vickers Shipbuilding nationalized and incorporated into British Shipbuilders. Vickers was the first shipyard of this group to return to the private sector. This occurred in 1986, after it acquired Cammell Laird. Cammel-Laird was later closed in 1993. In 1994 VSEL was subject to two takeover proposals, one from GEC and another from British Aerospace (BAe). VSEL was willing to participate in a merger with a larger company to reduce its exposure to cycles in warship production, particularly following the "Optio ...

EDSAC - Physical components. As soon as EDSAC was constructed, it immediately began serving the University's research needs. None of its components were experimental. It used mercury delay lines for memory, and derated vacuum tubes for logic. Input was via 5-hole punched tape and output was via a teleprinter. Initially registers were limited to an accumulator and a multiplier register. In 1953, David Wheeler, returning from a stay at the University of Illinois, designed an index register as an extension to the original EDSAC hardware. See also:

It was founded by Werner von Siemens on October 1, 1847, based on the telegraph he had invented that used a needle to point to the sequence of letters, instead of using the Morse code. The company – then called Telegraphen-Bauanstalt von Siemens & Halske – took occupation of its workshop on October 12. In 1848, the company built the first long-distance telegraph line in Europe, spanning 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Sir William Siemens (born Carl Wilhelm Siemens), started to re ...

GEC traces its origins to G.Binswanger and Company, an electrical goods wholesaler established in London during the 1880s by a German immigrant Gustav Binswanger (later Gustav Byng). Regarded as the year GEC was founded, 1886 saw Byng joined by a fellow immigrant, Hugo Hirst (later Lord Hirst), and the company changed its name to The General Electric Apparatus Company (G.Binswanger). This small business found early success with its unorthodox method of supplying electrical components over the counter. Hugo Hirst was an e ...

Suburban development of the mid twentieth century means that the built up area of Beeston is now continuous with the former villages of Chilwell to the west and Wollaton to the northeast, although Beeston is still separated from Bramcote to the northwest by the Beeston Fields Golf Course. There are two main areas of the town. North of the railway that runs through the town lies the main part, including the main shopping district. Southwards lies the housing area of Beeston Rylands. Beeston Rylands is more at risk of flooding from the River T ...

In September 1947, over a year after VE Day, the ROC held its first small scale exercise in southern England, which included for the first time substantial numbers of jet aircraft. Another year later the first large scale exercise took place; in the last two of its four days of this radar only was used. By the mid-1950s the greater speed of aircraft and the improved performance of radar lead to a reduced need by the RAF for the ROC's services in tracking aircraft; another rôle in defence against nuclear weapons was announced in June 1955.

It was developed by the UK Post Office (later to become British Telecom), GEC, Plessey, and Standard Telephones and Cables (STC), and first shown in public in 1979 at the Telecom 79 exhibition in Geneva Switzerland. The first System X unit to enter public service was in September 1980 and was installed in Baynard House, London and was a tandem junction unit which switched telephone calls between around 40 local exchanges. The first local digital exchange started operation in 1981 in Woodbridge, Suffolk (near BT's Research HQ at Martle ...

EDSAC's successor, EDSAC 2, was commissioned in 1958. In 1961 an EDSAC 2 version of Autocode, an Algol-like high-level programming language for scientists and engineers, was developed by D. F. Hartley. In the mid-60s, a successor to the EDSAC 2 was planned, but the move was instead made to the Titan, a prototype Atlas 2—the latter having been developed from the Atlas Computer of the University of Manchester, Ferranti, and Plessey. ...

The ROC had its beginnings during World War I. At the beginning of the war the need for an air raid warning system was not envisioned, but raids by Zeppelin airships starting in 1915 indicated that a warning system was needed. A system of observers was soon organised with a series of some 200 posts established in strategic areas, initially these were manned by troops, but these were soon replaced by police, coordinated by area with telephone contact to anti-aircaft (AA) defences. This system proved to ...

Beeston has a number of historic buildings, including its manor house and parish church of St. John the Baptist. The church dates from the 11th century but was largely rebuilt in 1843 by Sir George Gilbert Scott. Following the enclosure of the land surrounding Beeston in 1809 the area of St. John's Grove was allotted to the vicar of the parish church. In 1878 the land was acquired by the Beeston Land Society, a group of citizens, who divided the land out into 28 plots of between three-quarters and one acre and set out the wide ...

The Nottingham and Derby Road was turnpiked in 1758-9, and dis-turnpiked in 1870. A branch of the Nottingham and Ashby Turnpike Road, usually called the Sawley branch, went through Beeston. In 1831 an advertisement of the four-horse coach from Nottingham to Birmingham states that the coach calls at Beeston daily at 8.30 a.m., and in the opposite direction at 3.30 p.m. The Canal from the Trent, via Nottingham and Lenton, to Langley Mill, was completed in 1802. A branch canal from Lenton chain to Beeston Cut was made by the Trent ...
