Ferranti Thomson Sonar Systems
Ferranti or Ferranti International plc was a UK electrical engineering and equipment firm that operated for over a century from 1885 until it went bankrupt in 1993. The company was once a constituent of the FTSE 100 Index. The firm was known for work in the area of power grid systems and defence electronics. In addition, in 1951 Ferranti began selling an early computer, the Ferranti Mark 1. The Belgian subsidiary lives on as Ferranti Computer Systems and as of 1994 is part of the Nijkerk Holding. History Beginnings Sebastian Ziani de Ferranti established his first business Ferranti, Thompson and Ince in 1882. The company developed the Ferranti-Thompson Alternator. Ferranti focused on alternating current power distribution early on, and was one of the few UK experts. To avoid confusion, he is often referred to as Dr Ferranti to distinguish him from the Ferranti company itself. In 1885 Dr Ferranti established a new business, with Francis Ince and Charles Sparks as partners, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Mass Production
Mass production, also known as flow production or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before publication of the ''Britannica'' article. The concepts of mass production are applied to various kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to parts and assemblies of parts (household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, predate the Industrial Revolution by many centuries; however, ...

Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuse (explosives)
In an explosive, pyrotechnics, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific (and in particular in a military context), the term ''fuse'' describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term ''fuze'' is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronics, electronic components, such as a proximity fuze for an M107 projectile, M107 artillery shell, magnetometer, magnetic or acoustic signature, acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device. History Documented evidence suggests that the earliest fuses were first used by the Song Chinese between the 10th and 12th centuries. After the Chinese invented gunpowder, they began adapting its explosive properties for use in military technology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuze
In military munitions, a fuze (sometimes fuse) is the part of the device that initiates function. In some applications, such as torpedoes, a fuze may be identified by function as the exploder. The relative complexity of even the earliest fuze designs can be seen in cutaway diagrams. A fuze is a device that detonates a munition's explosive material under specified conditions. In addition, a fuze will have safety and arming mechanisms that protect users from premature or accidental detonation. For example, an artillery fuze's battery is activated by the high acceleration of cannon launch, and the fuze must be spinning rapidly before it will function. "Complete bore safety" can be achieved with mechanical shutters that isolate the detonator from the main charge until the shell is fired. A fuze may contain only the electronic or mechanical elements necessary to signal or actuate the detonator, but some fuzes contain a small amount of primary explosive to initiate the detonation. ...

National Enterprise Board
The National Enterprise Board (NEB) was a United Kingdom government body. It was set up in 1975 by the Labour government of Harold Wilson, to support the government's interventionist approach to industry. In 1981 the Conservative government of Margaret Thatcher, combined the NEB with the National Research Development Corporation (NRDC) to form the British Technology Group. Background The NEB was the brainchild of the economist Stuart Holland and the Shadow Secretary of State for Industry Tony Benn in the early-1970s, and was modelled on the Italian Istituto per la Ricostruzione Industriale (IRI), which was seen to have successfully restructured the Italian economy after World War II. In its original conception, the NEB was intended to extend public control and ownership of the economy, by taking a stake in the UK's leading manufacturing firms, which would then be required to make planning agreements to meet economic targets. Although the leadership of the Labour Party did not f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscometer
A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Thus, a rheometer can be considered as a special type of viscometer. Viscometers only measure under one flow condition. In general, either the fluid remains stationary and an object moves through it, or the object is stationary and the fluid moves past it. The drag caused by relative motion of the fluid and a surface is a measure of the viscosity. The flow conditions must have a sufficiently small value of Reynolds number for there to be laminar flow. At 20°C, the dynamic viscosity (kinematic viscosity × density) of water is 1.0038 mPa·s and its kinematic viscosity (product of flow time × factor) is 1.0022mm2/s. These values are used for calibrating certain types of viscometers. Standard laboratory viscometers for liquids U-tube viscometers These devices are also known as gl ...

EKCO
EKCO (from Eric Kirkham Cole Limited) was a British electronics company producing radio and television sets from 1924 until 1960. Expanding into plastic production for its own use, Ekco Plastics produced both radio cases and later domestic plastic products; the plastics company became Lin Pac Mouldings Ltd. Early history The company's founder Eric Kirkham Cole was born on 4 July 1901 at Prittlewell, Southend-on-Sea, Essex, and was educated at Southend Day Technical School, followed by a three-year apprenticeship. Cole and his future wife Muriel Bradshaw started out making radio sets in 1924.Oxford Dictionary of National Biography: Cole, Eric Kirkham by Rowland F. Pocock William Streatfield Verrells, a schoolmaster and freelance journalist from Southend-on-Sea, wrote an article in a local newspaper asking if it was possible to power a radio set from the mains electricity supply rather than batteries. Cole saw a possible business opportunity and set about building his battery e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moston, Greater Manchester
Moston is a suburb of Manchester, in North West England, approximately north-east of the city centre. Historically in Lancashire, Moston is a predominantly residential area, with a population of 14,518 at the 2011 census and an area of approximately . History The name Moston may derive from the Old English words ''moss'' and ''ton'', where ''moss'' usually referred to a place that was mossy, marshy or peat bog, and ''ton'' signified a town or settlement. The area of White Moss still retains these characteristics. Historical records of Moston date back as far as 1301. The earliest historical archives are of a charter from the Lord of the Manor of Manchester, Thomas Grelle. Although in 1320 Moston was called a hamlet of Manchester, in some deeds it is spoken of as lying within the township and parish of Ashton-under-Lyne. That the lords of Ashton had in early times rights in Moston also is shown by a fine of 1195, from which it appears that on a division Robert son of Bernard h ...

Empress Of Ireland
RMS ''Empress of Ireland'' was a British-built ocean liner that sank near the mouth of the Saint Lawrence River in Canada following a collision in thick fog with the Norwegian Collier (ship), collier in the early hours of 29 May 1914. Although the ship was equipped with watertight compartments and, in the aftermath of the Sinking of the RMS Titanic, ''Titanic'' disaster two years earlier, carried more than enough Lifeboat (shipboard), lifeboats for all aboard, she foundered in only 14 minutes. Of the 1,477 people on board, 1,012 died, making it the worst peacetime maritime disaster in Canadian history.Cd. 7609, p. 25. Fairfield Shipbuilding and Engineering built ''Empress of Ireland'' and her sister ship, , at Govan on the River Clyde, Clyde in Scotland. The liners were commissioned by Canadian Pacific Steamships or ''CPR'' for the Transatlantic crossing, North Atlantic route between Liverpool and Quebec City.
