ROF Patricroft
The Royal Ordnance Factory, ROF Patricroft, was an engineering factory was classified as a Medium Machine Shop. It was located in Patricroft, near the town of Eccles, in the City of Salford, Greater Manchester, England, adjacent to both the Liverpool & Manchester Railway and the Bridgewater Canal. The Ministry of Supply took over an existing engineering works, The Bridgewater Foundry, founded by James Nasmyth and Holbrook Gaskell, owned by the locomotive manufacturer Nasmyth, Gaskell & Company. They had ceased manufacturing locomotives in 1938 but continued, on a smaller scale, making steam hammers and machine tools. The company ceased trading in November 1940. The Ministry of Supply took over the works, on 1 June 1940, to convert it into a Royal Ordnance Factory. Staff from the Royal Arsenal, Woolwich, acted as agents for the Ministry of Supply. It reopened as an ROF in February 1941. The site consisted of a square mill-like building, known as ''The Tower'', and various ...

Royal Ordnance Factory
Royal Ordnance Factories (ROFs) was the collective name of the UK government's munitions factories during and after the Second World War. Until privatisation, in 1987, they were the responsibility of the Ministry of Supply, and later the Ministry of Defence. Origin Prior to the 1930s, Britain's ordnance manufacturing capability had been concentrated within the Royal Arsenal, Woolwich. In the late nineteenth century, the term 'Royal Ordnance Factories' began to be used collectively of the manufacturing departments of the Arsenal (principally the Royal Laboratory, Royal Gun Factory and Royal Carriage Works) which, though they shared the same site, operated independently of one another. This use of the term is seen in the name of the Royal Ordnance Factories Football Club (founded 1893) and it continued through the First World War. The emerging threat of aerial bombing, however, prompted the government to consider dispersing its ordnance factories around the country. Developm ...

Cotton Mill
A cotton mill is a building that houses spinning or weaving machinery for the production of yarn or cloth from cotton, an important product during the Industrial Revolution in the development of the factory system. Although some were driven by animal power, most early mills were built in rural areas at fast-flowing rivers and streams using water wheels for power. The development of viable steam engines by Boulton and Watt from 1781 led to the growth of larger, steam-powered mills allowing them to be concentrated in urban mill towns, like Manchester, which with neighbouring Salford had more than 50 mills by 1802. The mechanisation of the spinning process in the early factories was instrumental in the growth of the machine tool industry, enabling the construction of larger cotton mills. Limited companies were developed to construct mills, and the trading floors of the cotton exchange in Manchester, created a vast commercial city. Mills generated employment, drawing workers fr ...

British Aerospace
British Aerospace plc (BAe) was a British aircraft, munitions and defence-systems manufacturer. Its head office was at Warwick House in the Farnborough Aerospace Centre in Farnborough, Hampshire. Formed in 1977, in 1999 it purchased Marconi Electronic Systems, the defence electronics and naval shipbuilding subsidiary of the General Electric Company plc, to form BAE Systems. History Formation and privatisation The company has its origins in the Aircraft and Shipbuilding Industries Act 1977, which called for the nationalisation and merger of the British Aircraft Corporation, Hawker Siddeley Aviation, Hawker Siddeley Dynamics and Scottish Aviation. On 29 April 1977, the new entity was formed in the United Kingdom as a statutory corporation. Under the provisions of the ''British Aerospace Act 1980'' on 1 January the statutory corporation was transferred to a limited company, which then re-registered as a public limited company (plc), under the name "British Aerospace P ...

Public Limited Company
A public limited company (legally abbreviated to PLC or plc) is a type of public company under United Kingdom company law, some Commonwealth jurisdictions, and the Republic of Ireland. It is a limited liability company whose shares may be freely sold and traded to the public (although a PLC may also be privately held, often by another PLC), with a minimum share capital of £50,000 and usually with the letters PLC after its name. Similar companies in the United States are called ''publicly traded companies''. Public limited companies will also have a separate legal identity. A PLC can be either an unlisted or listed company on the stock exchanges. In the United Kingdom, a public limited company usually must include the words "public limited company" or the abbreviation "PLC" or "plc" at the end and as part of the legal company name. Welsh companies may instead choose to end their names with , an abbreviation for '. However, some public limited companies (mostly nationalis ...

Royal Ordnance
Royal Ordnance plc was formed on 2 January 1985 as a public corporation, owning the majority of what until then were the remaining United Kingdom government-owned Royal Ordnance Factories (abbreviated ROFs) which manufactured explosives, ammunition, small arms including the Lee–Enfield rifle, guns and military vehicles such as tanks. It owned some 16 factories; and employed about 19,000 staff. Royal Ordnance plc was bought by British Aerospace (BAe) in April 1987, which became BAE Systems in 1999. The name Royal Ordnance was retained for almost another twenty years; and the sites retained their former names, either as ''Royal Ordnance'' or later ''RO Defence'' sites. The Royal Ordnance name was dropped in 2004 and after having traded as Land Systems, the division is now known as Land UK. History Royal Ordnance Factories The Royal Ordnance Factories (ROFs) can trace their history back to 1560 with the founding of the Royal Gunpowder Factory (RGPF) at Waltham Abbey, Essex. T ...

Privatization
Privatization (also privatisation in British English) can mean several different things, most commonly referring to moving something from the public sector into the private sector. It is also sometimes used as a synonym for deregulation when a heavily regulated private company or industry becomes less regulated. Government functions and services may also be privatised (which may also be known as "franchising" or "out-sourcing"); in this case, private entities are tasked with the implementation of government programs or performance of government services that had previously been the purview of state-run agencies. Some examples include revenue collection, law enforcement, water supply, and prison management. Another definition is that privatization is the sale of a state-owned enterprise or municipally owned corporation to private investors; in this case shares may be traded in the public market for the first time, or for the first time since an enterprise's previous nati ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion ...

Mineral Oil
Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils. The name 'mineral oil' by itself is imprecise, having been used for many specific oils over the past few centuries. Other names, similarly imprecise, include 'white oil', 'paraffin oil', ' liquid paraffin' (a highly refined medical grade), (Latin), and 'liquid petroleum'. Most often, mineral oil is a liquid by-product of refining crude oil to make gasoline and other petroleum products. This type of mineral oil is a transparent, colorless oil, composed mainly of alkanes and cycloalkanes, related to petroleum jelly. It has a density of around . Nomenclature Some of the imprecision in the definition of the names used for mineral oil (such as 'white oil') reflects usage by consumers and merchants who did not know, and usually had no need of knowing, the oil's precise chemical mak ...

Welding
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often a ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
