Teledyne E2v
Teledyne e2v (previously known as e2v) is a manufacturer with its headquarters in England, that designs, develops and manufactures systems and components in healthcare, life sciences, space, transportation, defence and security and industrial markets. The company was previously known as English Electric Valve Company and for a short time Marconi Applied Technologies. e2v was acquired by US company Teledyne Technologies in March 2017. Company history The company began in the early 1940s as a part of the Marconi group, manufacturing magnetrons for defence radar systems. The company was first registered as a separate company in Chelmsford, Essex in 1947 under Simeon Aisenstein. Its initial name was the Phoenix Dynamo Co Ltd, though it immediately changed its name to English Electric Valve Company Ltd. In 1959, Bob Coulson established travelling-wave tube and microwave tube sections, and they were producing ceramic hydrogen thyratrons as well. By this time EEV was the largest hi- ...

Orthicon
Video camera tubes are devices based on the cathode-ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s. In these tubes, an cathode ray, electron beam is scanned across an image of the scene to be broadcast focused on a target. This generated a current that is dependent on the brightness of the image on the target at the scan point. The size of the striking ray is tiny compared to the size of the target, allowing 480–486 horizontal scan lines per image in the NTSC format, 576 lines in PAL, and as many as 1035 lines in Multiple sub-Nyquist sampling encoding, Hi-Vision. Cathode-ray tube Any vacuum tube which operates using a focused beam of electrons, originally called cathode rays, is known as a cathode-ray tube (CRT). These are usually seen as display devices as used in older (i. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sir Arthur Clarke Award
The Sir Arthur Clarke Award is a British award given annually since 2005 in recognition of notable contributions to Outer space, space exploration, particularly British achievements. The awards are presented by the Arthur C. Clarke Foundation, although the selection is delegated to the British Interplanetary Society, with the exception of the International award, whose recipient is voted on by the Foundation Nominations for the awards are made by members of the public, with shortlists drawn up by a panel of judges, who also choose the winner. Sir Arthur C Clarke, Sir Arthur C. Clarke chose a special award independently of the public nominations. History Founded in 2005, the idea for the awards was proposed by Dave Wright to Jerry Stone, who then suggested they be named after Arthur C. Clarke, Sir Arthur Clarke. Once permission was granted, Jerry Stone decided what the awards should look like, what categories should be included, and how they should be nominated and judged. Hav ...

Member Of The Most Excellent Order Of The British Empire
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding valuable service in a wide range of useful activities. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a Orders, decorations, and medals of the United Kingdom#Modern honours, knight if male or a dame (title), dame if female. There is also the related British Empire Medal, whose recipients are affiliated with the order, but are not members of it. The order was established on 4 June 1917 by King George V, who created the order to recognise 'such persons, male or female, as may have rendered or shall hereafter render important services to Our Empire'. Equal recognition was to be given for services rendered in the UK and overseas. Today, the majority of recipients are UK citizens, though a number of Commonwealth realms outside the UK continue to make appointments to the order. Honorary awards may be made to cit ...

Anode
An anode usually is an electrode of a polarized electrical device through which conventional current enters the device. This contrasts with a cathode, which is usually an electrode of the device through which conventional current leaves the device. A common mnemonic is ACID, for "anode current into device". The direction of conventional current (the flow of positive charges) in a circuit is opposite to the direction of electron flow, so (negatively charged) electrons flow from the anode of a galvanic cell, into an outside or external circuit connected to the cell. For example, the end of a household battery marked with a "+" is the cathode (while discharging). In both a galvanic cell and an electrolytic cell, the anode is the electrode at which the oxidation reaction occurs. In a galvanic cell the anode is the wire or plate having excess negative charge as a result of the oxidation reaction. In an electrolytic cell, the anode is the wire or plate upon which excess positive charge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device such as a lead-acid battery. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. Conventional current describes the direction in which positive charges move. Electrons, which are the carriers of current in most electrical systems, have a negative electrical charge, so the movement of electrons is ''opposite'' to that of the conventional current flow: this means that electrons flow ''into'' the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode. Charge flow Conventional current flows from cathode to anode outside the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating mode. Cathode polarity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Queen's Awards For Technology
The King's Awards for Enterprise, previously known as The Queen's Award for Enterprise, is an awards programme for British businesses and other organizations who excel at international trade, innovation, sustainable development or promoting opportunity (through social mobility). They are the highest official UK awards for British businesses. The scheme was established as The Queen's Award to Industry by a royal warrant of 30 November 1965, and awards are given for outstanding achievement by UK businesses in the categories of innovation, international trade, sustainable development and promoting opportunity through social mobility. Each award is valid for five years: recipients are invited to a royal reception and are presented with the award at their company premises by one of the King's representatives, a Lord-lieutenant. Recipients are also able to fly the King's Awards flag at their main office, and use the emblem on marketing materials such as packaging and adverts. History ...

Elmsford, New York
Elmsford is a village in Westchester County, New York, United States. It is part of the New York metropolitan area. Roughly one square mile, the village is fully contained within the borders of the town of Greenburgh. As of the 2010 census, the population of Elmsford was 4,664. History Elmsford was largely farmland throughout its early history. The construction of railroads in the late 19th century brought new prominence to the area, and in 1910 it was incorporated as a village. The area was known from colonial times as "Storm's Bridge" and later, "Hall's Corners", names derived from the principal landowners of the times. In 1870, the growing village was officially renamed "Elmsford" in honor of a local landmark, a giant elm tree (since deceased). The names Elmsford and Storm's Bridge are reminders of the nearby Saw Mill River, which once had significant tributaries flowing through the village. A longstanding legend holds that Elmsford is the birthplace of the term "cocktai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
