Eley Brothers
Eley Limited is a British manufacturer of firearms cartridges. Historically the company has produced a broad variety of ammunition, but today specialises in .22 Long Rifle cartridges for competitive target shooting. At the 2020 Tokyo Olympics, six of the twelve medals for cartridge rifle and pistol were won using Eley ammunition. History Founded as Eley Brothers by Charles and William Eley in London in the 1820s, the company purchased the patent rights to the "wire cartridge" in the spring or early summer of 1828. The patent for "wire cartridge" was issued by the English Patent Office on 28 November 1827 to Joshua Jenour under Patent No. 5570. Jenour had been born in Fleet Street, London in 1755 and had previously been the owner and manager of the ''Daily Advertiser'', a London newspaper. The 'wire cartridge' consisted of a wire cage which held the shot together during the first stages of its flight. In 1828, Charles and William Eley established a factory in Charlotte Street ...

Limited Company
In a limited company, the Legal liability, liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. Limited companies may be limited by Share (finance), shares or by guarantee. In a company limited by shares, the liability of members is limited to the unpaid value of shares. In a company limited by guarantee, the liability of owners is limited to such amount as the owners may undertake to contribute to the assets of the company, in the event of being wound up. The former may be further divided in public companies (public limited company, public limited companies) and private companies (private limited company, private limited companies). Who may become a member of a private limited company is restricted by law and by the company's rules. In contrast, anyone may buy shares in a public limited company. Limited companies can be found in most countries, although the detailed rules governing them vary widely. It is also com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angel Road
The North Circular Road (officially the A406 and sometimes known as simply the North Circular) is a ring road around Central London. It runs from Chiswick in the west to North Woolwich in the east via suburban north London, connecting various suburbs and other trunk roads in the region. Together with its counterpart, the South Circular Road, it mostly forms a ring road around central London, except for crossing of the River Thames, which is done by the Woolwich Ferry. The road was constructed in the Interwar period to connect local industrial communities and by pass London. It was upgraded after World War II, and was at one point planned to become a motorway as part of the controversial and ultimately cancelled London Ringways scheme. In the early 1990s, the road was extended to bypass Barking and meet the A13 north of Woolwich, though without a direct link to the ferry. The road's design varies from six-lane dual carriageway to urban streets; the latter, although sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Nobel
Alfred Bernhard Nobel ( ; ; 21 October 1833 – 10 December 1896) was a Swedish chemist, inventor, engineer, and businessman. He is known for inventing dynamite, as well as having bequeathed his fortune to establish the Nobel Prizes. He also made several other important contributions to science, holding 355 patents during his life. Born into the prominent Nobel family in Stockholm, Nobel displayed an early aptitude for science and learning, particularly in chemistry and languages; he became fluent in six languages and filed his first patent at the age of 24. He embarked on many business ventures with his family, most notably owning the company Bofors, which was an iron and steel producer that he had developed into a major manufacturer of cannons and other armaments. Nobel's most famous invention, dynamite, was an explosive made using nitroglycerin, which was patented in 1867. He further invented gelignite in 1875 and ballistite in 1887. Upon his death, Nobel donated his fortun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Munitions
Ammunition, also known as ammo, is the material fired, scattered, dropped, or detonated from any weapon or weapon system. The term includes both expendable weapons (e.g., bombs, missiles, grenades, land mines), and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across diff ...

Kynoch
Kynoch was a manufacturer of ammunition that was later incorporated into ICI, but remained as a brand name for sporting cartridges. History The firm of Pursall and Phillips operated a 'percussion cap manufactory' at Whittall Street, in Birmingham, in the mid 19th century. In 1856, Scottish entrepreneur George Kynoch joined the company. An explosion in 1859 destroyed the works, killing 19 of the 70 employees. As a result, the firm moved to Witton in 1862, on a site adjacent to the London and North Western Railway's Grand Junction line. In 1863, Kynoch took over the business, which was subsequently renamed G. Kynoch and Co. A further series of explosions in the 1860s and in 1870 led to dozens of deaths and hundreds of injuries. In 1895 Kynoch built an explosives factory east of Shell Haven Creek, Essex (now known as Coryton). This opened in 1897, with an estate for employees called Kynochtown. Products included cordite, guncotton, gunpowder, and cartridges. After World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft. World War I was one of the List of wars by death toll, deadliest conflicts in history, resulting in an estimated World War I casualties, 10 million military dead and more than 20 million wounded, plus some 10 million civilian de ...

Mass Production
Mass production, also known as mass production, series production, series manufacture, 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 the publication of the ''Britannica'' article. The idea of mass production is applied to many kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to clothing, textiles, parts and assemblies of parts ( household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shot Tower
A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is primarily used for projectiles in shotguns, and for ballast, radiation shielding, and other applications for which small lead balls are useful. Shot making Process In a shot tower, lead is heated until molten, then dropped through a copper sieve high in the tower. The liquid lead forms tiny spherical balls by surface tension, and solidifies as it falls. The partially cooled balls are caught at the floor of the tower in a water-filled basin.. The now fully cooled balls are checked for roundness and sorted by size; those that are "out of round" are remelted. A slightly inclined table is used for checking roundness. To make larger shot sizes, a copper sieve with larger holes is used. The maximum size is limited by the height of the tower, because larger shot sizes must fall farther to solidify. A shot tower with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistics
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, unguided bombs, rockets and the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. A ballistic body is a free-moving body with momentum, which can be subject to forces such as those exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight. A ballistic missile is a missile that is missile guidance, guided only during the relatively brief initial phase of powered flight, with the trajectory subsequently governed by the laws of classical mechanics, in contrast to (for example) a cruise missile, which is aerodynamics, aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones, spears, and the throwing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strike Action
Strike action, also called labor strike, labour strike in British English, or simply strike, is a work stoppage caused by the mass refusal of employees to Working class, work. A strike usually takes place in response to employee grievances. Strikes became common during the Industrial Revolution, when Labour economics, mass labor became important in factories and mines. As striking became a more common practice, governments were often pushed to act (either by private business or by union workers). When government intervention occurred, it was rarely neutral or amicable. Early strikes were often deemed unlawful conspiracies or anti-competitive cartel action and many were subject to massive legal repression by state police, federal military power, and federal courts. Many Western nations legalized striking under certain conditions in the late 19th and early 20th centuries. Strikes are sometimes used to pressure governments to change policies. Occasionally, strikes destabilize the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The .303-inch bore diameter is measured between rifling Rifling, lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in United Kingdom, Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth of Nations, Commonwealth military cartridge for rifles and machine guns from 1889 until it was replaced by the 7.62×51mm NATO in the 1950s.
