Kenyon Taylor
Maurice Kenyon Taylor (26 June 1908 – 29 June 1986) was an English electrical engineer and inventor, responsible for many diverse technological developments and inventions, producing over 70 patents during his career. He spent most of his career at Ferranti, first in Manchester, then Edinburgh and finally moving to Canada where he led development at their Toronto-area operations, Ferranti-Packard. Early life Taylor was born near Balloch, Scotland to English parents; the son of Maurice Grove Taylor. He was educated at Oundle Public school and passed the entrance exam to King's College, Cambridge, where he studied for a year before moving to Manchester University. Ferranti Manchester Kenyon Taylor came to the attention of Albert Hall who was the personal assistant of Sebastian Ziani de Ferranti of the Ferranti company Manchester and joined them as a lab boy in March 1931. For some time, Ferranti had been contracted by J P Coats of Paisley to develop a very high speed cotton doubl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common history and culture. The English identity is of History of Anglo-Saxon England, Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

Mechanical Television
Mechanical television or mechanical scan television is a television system that relies on a mechanical scanning device, such as a rotating disk with holes in it or a rotating mirror drum, to scan the scene and generate the video signal, and a similar mechanical device at the receiver to display the picture. This contrasts with vacuum tube electronic television technology, using electron beam scanning methods, for example in cathode ray tube (CRT) televisions. Subsequently, modern solid-state liquid-crystal displays (LCD) are now used to create and display television pictures. Mechanical-scanning methods were used in the earliest experimental television systems in the 1920s and 1930s. One of the first experimental wireless television transmissions was by John Logie Baird on October 2, 1925, in London. By 1928 many radio stations were broadcasting experimental television programs using mechanical systems. However the technology never produced images of sufficient quality to become ...

Induction Loop
An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence indicators. A common modern use for induction loops is to provide hearing assistance to hearing-aid users. Applications Vehicle detection Vehicle detection loops, called ''inductive-loop traffic detectors'', can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement. The electronics unit applies alternating current electrical energy onto the wire loops at frequencies between 10 k Hz to 200 kHz, depending on the model. The inductive-loop system behaves as a tuned electrical circuit in which the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ReserVec
ReserVec was a computerized reservation system developed by Ferranti Canada for Trans-Canada Airlines (TCA, today's Air Canada) in the late 1950s. It appears to be the first such system ever developed, predating the more famous SABRE system in the United States by about two years. Although Ferranti had high hopes that the system would be used by other airlines, no further sales were forthcoming and development of the system ended. Major portions of the transistor-based circuit design were put to good use in the Ferranti-Packard 6000 computer, which would later go on to see major sales in Europe as the ICT 1904. Background In the early 1950s the airline industry was undergoing explosive growth. A serious limiting factor was the time taken to make a single booking, which could take upwards of 90 minutes in total. TCA found their bookings typically involved between three and seven calls to the centralized booking centre in Toronto, where telephone operators would scan flight statu ...

Trackball
A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down ball mouse with an exposed protruding ball. Users roll the ball to position the on-screen pointer, using their thumb, fingers, or the palm of the hand, while using the fingertips to press the buttons. With most trackballs, operators have to lift their finger, thumb or hand and reposition in on the ball to continue rolling, whereas a mouse would have to be lifted itself and re-positioned. Some trackballs have notably low friction, as well as being made of a dense material such as phenolic resin, so they can be spun to make them coast. The trackball's buttons may be in similar positions to those of a mouse, or configured to suit the user. Large trackballs are common on CAD workstations for easy precision. Before the advent of the touchpad, small trackballs were common on portable computers (such as the BlackBerry Tour) wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DATAR
DATAR, short for ''Digital Automated Tracking and Resolving'', was a pioneering computerized battlefield information system. DATAR combined the data from all of the sensors in a naval task force into a single "overall view" that was then transmitted back to all of the ships and displayed on plan-position indicators similar to radar displays. Commanders could then see information from everywhere, not just their own ship's sensors. Development of the DATAR system was spurred by the Royal Navy's work on the Comprehensive Display System (CDS), which Canadian engineers were familiar with. The project was started by the Royal Canadian Navy in partnership with Ferranti Canada (later known as Ferranti-Packard) in 1949. They were aware of CDS and a US Navy project along similar lines but believed their solution was so superior that they would eventually be able to develop the system on behalf of all three forces. They also believed sales were possible to the Royal Canadian Air Force and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williamson Amplifier
The Williamson amplifier is a four-stage, push-pull, Class A triode-output valve audio power amplifier designed by D. T. N. Williamson during World War II. The original circuit, published in 1947 and addressed to the worldwide do it yourself community, set the standard of high fidelity sound reproduction and served as a benchmark or reference amplifier design throughout the 1950s. The original circuit was copied by hundreds of thousands amateurs worldwide. It was an absolute favourite on the DIY scene of the 1950s, and in the beginning of the decade also dominated British and North American markets for factory-assembled amplifiers. The Williamson circuit was based on the 1934 '' Wireless World Quality Amplifier'' by Walter Cocking, with an additional error amplifier stage and a global negative feedback loop. Deep feedback, triode-connected KT66 power tetrodes, conservative choice of standing currents, and the use of wide-bandwidth output transformer all contributed to the ...

John Toothill (industrialist)
Sir John Norman Toothill Order of the British Empire, CBE (11 November 1908 – 5 July 1986) was an English people, English electrical engineer who rose to be Managing Director of Ferranti. He was the author of the ground-breaking Toothill Report of 1961 and was one of the creators of the modern Scottish electronics industry. Life He was born on 11 November 1908 at 13 Trafford Road in Leicester, the only son of John Harold Toothill, an engineer's fitter, and his wife, Helena Gibbins. Educated at Beaminster Grammar School in Dorset, Toothill left school at the age of seventeen to be apprenticed to Tilling-Stevens, Tilling Stevens Ltd, a company in Maidstone which made buses. From there he moved on to Hoffman (Cleveland automobile), Hoffman Manufacturing and then to Harris Lebus, a furniture manufacturer.TOOTHILL, Sir John ...

IFF Mark III
IFF Mark III, also known as ARI.5025 in the UK or SCR.595 in the US, was the Allied Forces standard identification friend or foe (IFF) system from 1943 until well after the end of World War II. It was widely used by aircraft, ships, and submarines, as well as in various adaptations for secondary purposes like search and rescue. 500 units were also supplied to the Soviet Union during the war. Mark III replaced the earlier Mark II which had been in service since 1940. Mark II had an antenna that received signals from radar systems, amplified them, and returned them. This caused the ''blip'' on the radar display to become larger, indicating a friendly aircraft. As the number of radar systems on different frequencies proliferated through the mid-war period, the number of models of Mark II had to do the same. Aircraft could never be sure their IFF would respond to the radars they flew over. Freddie Williams had suggested using a single separate frequency for IFF as early as 1940, bu ...

Identification Friend Or Foe
Identification, friend or foe (IFF) is an identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as equipment malfunction, and parties in the area ...

405-line Television System
The 405-line monochrome analogue television broadcasting system was the first fully electronic television system to be used in regular broadcasting. The number of television lines influences the image resolution, or quality of the picture. It was introduced with the BBC Television Service in 1936, suspended for the duration of World War II, and remained in operation in the UK until 1985. It was also used between 1961 and 1982 in Ireland, as well as from 1957 to 1973 for the Rediffusion Television cable service in Hong Kong. Sometimes called the Marconi-EMI system, it was developed in 1934 by the EMI Research Team led by Isaac Shoenberg. The figure of 405 lines had been chosen following discussions over Sunday lunch at the home of Alan Blumlein. The system used interlacing; EMI had been experimenting with a 243-line all-electronic interlaced system since 1933. In the 405 system the scanning lines were broadcast in two complementary fields, 50 times per second, creating 25 frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
