Beeston Hill Y Station
Beeston Hill Y Station was a secret listening station located on the summit of Beeston Hill, Sheringham in the English county of Norfolk. The chain of Y stations were the front line of the War Office's Bletchley Park, which had the code name station X. Description This Y Station was a specially constructed wireless interception facility which was also used for direction finding on enemy wireless transmissions. This became particularly important in the Battle of the Atlantic (1939–1945) where locating U-boats became a critical issue. Admiral Dönitz told his commanders that they could not be located if they limited their wireless transmissions to under 30 seconds, but skilled direction finding operators were able to locate the origin of their signals in as little as 6 seconds. There were several of these stations around the east coast, and by triangulating the signals the exact location of enemy shipping could be pinpointed. Operation The equipment used for direction findi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ultra
adopted by British military intelligence in June 1941 for wartime signals intelligence obtained by breaking high-level encrypted enemy radio and teleprinter communications at the Government Code and Cypher School (GC&CS) at Bletchley Park. ''Ultra'' eventually became the standard designation among the western Allies for all such intelligence. The name arose because the intelligence obtained was considered more important than that designated by the highest British security classification then used (''Most Secret'') and so was regarded as being ''Ultra Secret''. Several other cryptonyms had been used for such intelligence. The code name ''Boniface'' was used as a cover name for ''Ultra''. In order to ensure that the successful code-breaking did not become apparent to the Germans, British intelligence created a fictional MI6 master spy, Boniface, who controlled a fictional series of agents throughout Germany. Information obtained through code-breaking was often attributed to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Security Service
MI8, or ''Military Intelligence, Section 8'' was a British Military Intelligence group responsible for signals intelligence and was created in 1914. It originally consisted of four sections: MI8(a), which dealt with wireless policy; MI8(b), based at the General Post Office, dealt with commercial and trade cables; MI8(c) dealt with the distribution of intelligence derived from censorship; and MI8(d), which liaised with the cable companies. During World War I MI8 officers were posted to the cable terminals at Poldhu Point and Mullion in Cornwall and Clifden in County Galway, continued until 1917 when the work was taken over by the Admiralty. In WW2, MI8 was responsible for the extensive War Office Y Group and briefly, for the Radio Security Service. History MI8 was the signals intelligence department of the War Office that ran a worldwide Y-stations network. Additionally, for an 18-month period, from late 1939 to mid 1941, it also ran the Radio Security Service, under the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Radio Company
The National Radio Company, headquartered in Malden, Massachusetts, United States, was an American manufacturer of radio equipment from 1914 to 1991. History The company was incorporated, in 1914, as the "National Toy Company", but by 1916 had included household appliances in their product range. This expansion led to the name change to the "National Company, Inc.". By 1923 the product line included toys, food mixers, and radio components. Radio components were to play an important part in the company's growth in the mid-1920s as they moved into the large scale manufacture of capacitors. It was at this time that two engineers from Harvard University, Fred H. Drake and Glen Browning, approached National to manufacture components to their specifications for a radio receiver of their own design. This relationship led to the production and sale of the "National Regenaformer" kit for home construction of the Browning-Drake design. The set was capable of tuning the standard AM broadcast ...

Women's Royal Naval Service
The Women's Royal Naval Service (WRNS; popularly and officially known as the Wrens) was the women's branch of the United Kingdom's Royal Navy. First formed in 1917 for the First World War, it was disbanded in 1919, then revived in 1939 at the beginning of the Second World War, remaining active until integrated into the Royal Navy in 1993. WRNS included cooks, clerks, wireless telegraphists, radar plotters, weapons analysts, range assessors, electricians and air mechanics. History First World War The Wrens were formed in 1917 during the First World War. On 10 October 1918, nineteen-year-old Josephine Carr from Cork became the first Wren to die on active service, when her ship, the RMS ''Leinster'' was torpedoed. By the end of the war the WRNS had 5,500 members, 500 of them officers. In addition, about 2,000 members of the WRAF had previously served with the WRNS supporting the Royal Naval Air Service and were transferred on the creation of the Royal Air Force. It was disb ...

Shingle Beach
A shingle beach (also referred to as rocky beach or pebble beach) is a beach which is armoured with pebbles or small- to medium-sized cobbles (as opposed to fine sand). Typically, the stone composition may grade from characteristic sizes ranging from diameter. While this beach landform is most commonly found in Europe, examples are found in Bahrain, North America, and a number of other world regions, such as the west coast of New Zealand's South Island, where they are associated with the shingle fans of braided rivers. Though created at shorelines, post-glacial rebound can raise shingle beaches as high as above sea level, as on the High Coast in Sweden. The ecosystems formed by this unique association of rock and sand allow colonization by a variety of rare and endangered species. Formation Shingle beaches are typically steep, because the waves easily flow through the coarse, porous surface of the beach, decreasing the effect of backwash erosion and increasing the formati ...

The London Brick Company
The London Brick Company, owned by Forterra plc, is a leading British manufacturer of bricks. History The London Brick Company owes its origins to John Cathles Hill, a developer-architect who built houses in London and Peterborough. In 1889, Hill bought the small T.W. Hardy & Sons brickyard at Fletton in Peterborough, and the business was incorporated as the London Brick Company in 1900. "Fletton" is the generic name given to bricks made from lower Oxford clay which have a low fuel cost due to the carbonaceous content of the clay. Hill ran into financial difficulties and, in 1912, a receiver was appointed to run London Brick. Hill died in 1915, but after the receiver was discharged in 1919, Hill's son continued to run the company. The capital intensive Fletton brick industry suffered from substantial variations in demand. After the First World War, amalgamations were proposed. In 1923, London Brick merged with Malcolm Stewart's B.J. Forder, who, along with London Brick, was o ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...

Octagon
In geometry, an octagon (from the Greek ὀκτάγωνον ''oktágōnon'', "eight angles") is an eight-sided polygon or 8-gon. A '' regular octagon'' has Schläfli symbol and can also be constructed as a quasiregular truncated square, t, which alternates two types of edges. A truncated octagon, t is a hexadecagon, . A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. Properties of the general octagon The sum of all the internal angles of any octagon is 1080°. As with all polygons, the external angles total 360°. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal (that is, whose diagonals are equal in length and at right angles to each other).Dao Thanh Oai (2015), "Equilatera ...
