Frederick Abel
Sir Frederick Augustus Abel, 1st Baronet (17 July 18276 September 1902) was an English chemist who was recognised as the leading British authority on explosives. He is best known for the invention of cordite as a replacement for gunpowder in firearms. Education Born in London as son of Johann Leopold Abel, Abel studied chemistry at the University of Westminster, Royal Polytechnic Institution and in 1845 became one of the original 26 students of A. W. von Hofmann at the Royal College of Chemistry (now a constituent of Imperial College London). In 1852 he was appointed lecturer in chemistry at the Royal Military Academy, Woolwich, succeeding Michael Faraday, who had held that post since 1829. Early career From 1854 until 1888 Abel served as ordnance chemist at the Chemical Establishment of the Royal Arsenal at Woolwich, establishing himself as the leading British authority on explosives. Three years later was appointed chemist to the War Department (UK), War Department and chemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whitehall Court
Whitehall Court in the City of Westminster, England, is one contiguous building but consists of two separate constructions. The south end was designed by Thomas Archer and A. Green and constructed as a block of luxury residential apartments in 1884 while the north end, occupied by the National Liberal Club, was designed by Alfred Waterhouse and completed in 1887. The building was developed speculatively by the Liberal MP and property developer Jabez Balfour, through the Liberator Building Society which he controlled. In 1892 the Society collapsed, leaving thousands of investors penniless. Instead of advancing money to home buyers, the Society had advanced money to property companies to buy properties owned by Balfour, at a high price. Well-known residents have included William Gladstone, Lord Kitchener, Grand Duke Michael Alexandrovich of Russia, George Bernard Shaw and Hall Caine. The building was used as Secret Intelligence Service (MI6) headquarters until the end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Act Of Parliament
Acts of Parliament, sometimes referred to as primary legislation, are texts of law passed by the Legislature, legislative body of a jurisdiction (often a parliament or council). In most countries with a parliamentary system of government, acts of parliament begin as a Bill (law), bill, which the legislature votes on. Depending on the structure of government, this text may then be subject to assent or approval from the Executive (government), executive branch. Bills A draft act of parliament is known as a Bill (proposed law), bill. In other words, a bill is a proposed law that needs to be discussed in the parliament before it can become a law. In territories with a Westminster system, most bills that have any possibility of becoming law are introduced into parliament by the government. This will usually happen following the publication of a "white paper", setting out the issues and the way in which the proposed new law is intended to deal with them. A bill may also be introduced in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash Point
The flash point of a material is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture". (EN 60079-10-1) The flash point is sometimes confused with the autoignition temperature, the temperature that causes spontaneous ignition. The fire point is the lowest temperature at which the vapors keep burning after the ignition source is removed. It is higher than the flash point, because at the flash point vapor may not be produced fast enough to sustain combustion. Neither flash point nor fire point depends directly on the ignition source temperature, but ignition source temperature is far higher than either the flash or fire point. Fuels The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (also known as gasoline), and combustible fuels, such as diesel. It is also used to characterize the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abel Test
The Abel test is a method developed by the British chemist Frederick Abel (1827–1902) to determine the flash point of a given sample of petroleum in order to ascertain the temperature at which it could safely be stored or used. The test was mandated by the British Petroleum Act 1879 The Petroleum Act 1879 ( 42 & 43 Vict. c. 47) is an Act of the Parliament of the United Kingdom which continued and amended the Petroleum Act 1871.

Sir Andrew Noble, 1st Baronet
Sir Andrew Noble, 1st Baronet (13 September 1831 – 22 October 1915) was a Scottish physicist noted for his work on ballistics and gunnery. Early life Born at Greenock, he was educated at Edinburgh Academy and at the Royal Military Academy, Woolwich. He was commissioned in the Royal Artillery in 1849, promoted captain in 1855 and became secretary of the Royal Artillery Institution. He was secretary of the British government select committee on the replacement of smooth-bore cannon with rifled artillery and carried out research on the subject. In 1859 he became Assistant-Inspector of Artillery and in 1860 a member of the Ordnance Select Committee and of the Committee on Explosives, remaining on the committee until it was dissolved in 1880. Notable work In 1860 he joined Armstrong's armaments works in Elswick, Newcastle-upon-Tyne, first as joint manager and, from 1861, as a partner, where he continued research into artillery, in particular inventing ways of measuring bre ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Lords
The House of Lords, also known as the House of Peers, is the Bicameralism, upper house of the Parliament of the United Kingdom. Membership is by Life peer, appointment, Hereditary peer, heredity or Lords Spiritual, official function. Like the House of Commons of the United Kingdom, House of Commons, it meets in the Palace of Westminster in London, England. The House of Lords scrutinises Bill (law), bills that have been approved by the House of Commons. It regularly reviews and amends bills from the Commons. While it is unable to prevent bills passing into law, except in certain limited circumstances, it can delay bills and force the Commons to reconsider their decisions. In this capacity, the House of Lords acts as a check on the more powerful House of Commons that is independent of the electoral process. While members of the Lords may also take on roles as government ministers, high-ranking officials such as cabinet ministers are usually drawn from the Commons. The House of Lo ...

Ballistite
Ballistite is a smokeless propellant made from two high explosives, nitrocellulose and nitroglycerine. It was developed and patented by Alfred Nobel in the late 19th century. Military adoption Alfred Nobel patented https://www.nobelprize.org/alfred-nobel/list-of-alfred-nobels-patents/Ballistite in 1887 while he was living in Paris. His formulation was composed of 10% camphor and equal parts nitroglycerine and collodion. The camphor reacted with any acidic products of the chemical breakdown of the two explosives. This both stabilized the explosive against further decomposition and prevented spontaneous explosions. However, camphor tends to evaporate over time, leaving a potentially unstable mixture. Nobel's patent specified that the nitrocellulose should be "of the well-known soluble kind". He offered to sell the rights of the new explosive to the French government, but they declined, largely because they had just adopted Poudre B for military use. He subsequently licensed the ...

Alfred Nobel
Alfred Bernhard Nobel ( , ; 21 October 1833 – 10 December 1896) was a Swedes, Swedish chemist, engineer, inventor, businessman, and Philanthropy, philanthropist. He is best known for having bequeathed his fortune to establish the Nobel Prize, though he also made several important contributions to science, holding 355 patents in his lifetime. Nobel's most famous invention was dynamite, a safer and easier means of harnessing the explosive power of nitroglycerin; it was patented in 1867. 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 age 24. He embarked on many business ventures Nobel family, with his family, most notably owning Bofors, an iron and steel producer that he developed into a major manufacturer of cannons and other armaments. Nobel was later inspired to donate his fortune to the Nobel Prize institution, which would annually recognize those who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
