M61 Motorway
The M61 is a motorway in North West England between Manchester and Preston, linking the M60 Manchester Orbital Motorway with the M6 Midlands-to-Scotland motorway. It runs from the A580 near Wardley and heads northwest past Bolton, Horwich and Chorley to join the M6 near Bamber Bridge, just north of the junction between the M6 and M65. It runs parallel to the A6, to its northeast, for the entirety of its length, essentially bypassing the towns and villages the A6 runs through between Manchester and Preston. History The Horwich to Worsley section began on Wednesday 1 January 1969, costing £12,434,103, to open by the end of December 1970, built by the Alfred McAlpine and Leonard Fairclough & Son consortium. Services The M61 has one service station: Rivington services (formerly Anderton Services and Bolton West services), located between Junctions 6 and 8 (as Junction 7 was never built). This motorway service area was used in the filming of "The Services", a pilot epis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M-61 (Michigan Highway)
M-61 is a state trunkline highway in the US state of Michigan that runs between Marion and Standish. The highway runs along the boundary area between Northern Michigan and Central Michigan in the Lower Peninsula. M-61 runs through rural forestland connecting several smaller communities together as it connects M-115, US Highway 127 (US 127), Interstate 75 (I-75) and US 23. Less than 10,000 vehicles a day use various segments of the roadway on average. The trunkline was first designated along a portion of its current alignment by 1919. M-61 was extended in segments through 1940, with a truncation at the end of the 1950s. One change in routing in the 1970s resulted in the current routing of the highway. Route description M-61 starts in eastern Osceola County south of Marion at an intersection with M-115. It runs eastward and meets M-66 before crossing into Clare County. The highway runs along the boundary between the regions of Northern and Central Michigan throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NOHAB
NOHAB (Nydqvist & Holm AB) was a manufacturing company based in the city of Trollhättan, Sweden. History The company was founded by Antenor Nydqvist, Johan Magnus Lidström and Carl Olof Holm in 1847 as ''Trollhättans Mekaniska Verkstad'' as a manufacturer of turbines for hydraulic power plants. In 1865, the company made its first steam locomotive and in 1912 the 1,000th locomotive steamed out of the factory. In Nohab's anniversary book "The Thousand Locomotive" from 1912, it's mentioned that the company also manufactured davits for Titanic's lifeboats. In 1916 the company was reconstituted as a limited company and became NOHAB. In 1920, NOHAB received an order of 1000 locomotives from Soviet Russia. Only 500 were delivered between 1921 and 1924. In 1924, Nohab built three steam locomotives, 4-6-0 ones for with the respective builder's plates #1727, #1728 and #1729 for Estrada de Ferro Rio d'Ouro in the state of Rio de Janeiro (Brazil). According to E.F. Rio d'Ouro's su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messier 61
Messier 61 (also known as M61 or NGC 4303) is an intermediate barred spiral galaxy in the Virgo Cluster of galaxies. It was first discovered by Barnaba Oriani on May 5, 1779, six days before Charles Messier discovered the same galaxy. Messier had observed it on the same night as Oriani but had mistaken it for a comet. Its distance has been estimated to be 45.61 million light years from the Milky Way Galaxy. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. Properties M61 is one of the largest members of Virgo Cluster, and belongs to a smaller subgroup known as the ''S Cloud''. The morphological classification of SAB(rs)bc indicates a weakly-barred spiral (SAB) with the suggestion of a ring structure (rs) and moderate to loosely wound spiral arms. It has an active galactic nucleus and is classified as a starburst galaxy containing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M61 Vulcan
The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament of United States military fixed-wing aircraft for over sixty years. The M61 was originally produced by General Electric. After several mergers and acquisitions, it is currently produced by General Dynamics. Development At the end of World War II, the United States Army Air Forces began to consider new directions for future military aircraft guns. The higher speeds of jet-powered fighter aircraft meant that achieving an effective number of hits would be extremely difficult without a much higher volume of fire. While captured German designs (principally the Mauser MG 213C) showed the potential of the single-barrel revolver cannon, the practical rate of fire of such a design was still lim ...

M61 (grenade)
The M26 is a fragmentation hand grenade developed by the United States military. It entered service around 1952 and was used in combat during the Korean War. Its distinct lemon shape led it to being nicknamed the "lemon grenade" (compare the Russian F1 grenade and American Mk 2 "pineapple" grenade, with similar nicknames). Fragmentation is enhanced by a special notched fragmentation coil that lies along the inside of the grenade's body. This coil had a circular cross-section in the M26 grenade and an improved square cross-section in the M26A1 and later designs. The grenades were stored inside two-part cylindrical fiberboard shipping tubes (Container M289) and were packed 25 or 30 to a crate. History The M26 was developed as a result of studies on the Mk 2. Unlike its previous counterpart, its M204A1 fuse creates no tell-tale smoke or sparks when ignited and its powder train is almost silent while it burns down. Its Composition B filler was considered safer than the fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Å korpion Vz
The Škorpion vz. 61 (or Sa vz. 61 Skorpion) is a Czechoslovak machine pistol developed in 1959 by Miroslav Rybář (1924–1970) and produced under the official designation Samopal vzor 61 ("submachine gun model 1961") by the Česká zbrojovka arms factory in Uherský Brod from 1963 to 1979. Although it was developed for use with security forces, the weapon was also accepted into service with the Czechoslovak Army as a personal sidearm for lower-ranking army staff, vehicle drivers, armoured vehicle personnel and special forces. Currently the weapon is in use with the armed forces of several countries as a sidearm. A variant of the Škorpion, containing a synthetic pistol grip in place of the wooden original, was built under license in Yugoslavia, designated ''M84''. A civilian, semi-automatic version was also produced, known as the ''M84A'', also available in .380 ACP (9×17mm Short). History The Škorpion was developed in the late 1950s by Miroslav Rybář with the working n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
