High Duty Alloys Ltd.
The Hiduminium alloys or R.R. alloys are a series of high-strength, high-temperature aluminium alloys, developed for aircraft use by Rolls-Royce ("RR") before World War II. They were manufactured and later developed by High Duty Alloys Ltd. The name ''Hi''-''Du''-Minium is derived from that of ''Hi''gh ''Du''ty Alu''minium'' Alloys. The first of these Hiduminium alloys was termed '' 'R.R.50' ''. This alloy was first developed for motor-racing pistons, and was only later adopted for aircraft engine use. It was a development of the earlier Y alloy, the first of the nickel-containing light aluminium alloys. These alloys are one of the three main groups of high-strength aluminium alloys, the nickel-aluminium alloys having the advantage of retaining strength at high temperatures, making them particularly useful for pistons. Early adoption The alloys were in limited use for aircraft by 1929, being used in the Rolls-Royce R engine that was successful in the Schneider Tro ...

Armstrong-Siddeley Special Six Engine, In Hiduminium Alloy (Autocar Handbook, 13th Ed, 1935)
Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury vehicles and aircraft engines. The company was created following the purchase by Armstrong Whitworth of Siddeley-Deasy, a manufacturer of fine motor cars that were marketed to the top echelon of society. After the merge of companies, this focus on quality continued throughout in the production of cars, aircraft engines, gearboxes for tanks and buses, rocket and torpedo motors, and the development of railcars. Company mergers and takeovers with Hawker Aviation and Bristol Aero Engines saw the continuation of the car production which ceased in August 1960. The company was absorbed into the Rolls-Royce conglomerate which was interested in the aircraft and aircraft engine business. Eventually, the remaining spares and all motor car interests were sold to the Armstrong Siddeley Owners Club Ltd, which now ...

Italo Balbo
Italo Balbo (6 June 1896 – 28 June 1940) was an Italian fascist politician and Blackshirts' leader who served as Italy's Marshal of the Air Force, Governor-General of Libya and Commander-in-Chief of Italian North Africa. Due to his young age, he was sometimes seen as a possible successor of dictator Benito Mussolini. After serving in World War I, Balbo became the leading Fascist organizer in his home region of Ferrara. He was one of the four principal architects (''Quadrumviri del Fascismo'') of the March on Rome that brought Mussolini and the Fascists to power in 1922, along with Michele Bianchi, Emilio De Bono and Cesare Maria De Vecchi. In 1926, he began the task of building the Italian Royal Air Force and took a leading role in popularizing aviation in Italy, and promoting Italian aviation to the world. In 1933, perhaps to relieve tensions surrounding him in Italy, he was given the government of Italian Libya, where he resided for the remainder of his life. Balbo, ...

John Siddeley, 1st Baron Kenilworth
John Davenport Siddeley, 1st Baron Kenilworth (5 August 1866 – 3 November 1953), was a pioneer of the motor industry in the United Kingdom, manufacturing aero engines and airframes as well as motor vehicles. Career The eldest son of William Siddeley and his wife born Elizabeth Davenport, J D Siddeley was born in Longsight, Manchester in 1866 and first worked for his father as an apprentice hosier but took night classes in draughting. In 1892, the young bicycle racer and designer was hired as a draughtsman by the Humber Cycle Company. The then managing director of Dunlop picked him out at Humber and hired Siddeley as Dunlop's Belfast sales manager. In 1900 as managing director of Dunlop's Midlands subsidiary Clipper Tyre Company he gained prominence in the motor industry by driving a 6 hp Daimler car through England's Thousand Miles Trial with marked success.Lord Kenilworth.

Armstrong Siddeley Jaguar
The Armstrong Siddeley Jaguar was an aircraft engine developed by Armstrong Siddeley. The Jaguar was a petrol-fuelled air-cooled 14-cylinder two-row radial engine design. The Jaguar III was first used in 1923, followed in 1925 by the Jaguar IV and in 1927 by the Jaguar VI. In 1925 the Jaguar became the first production aero engine incorporating a geared supercharger. Design and development The Jaguar was developed from the Royal Aircraft Factory RAF.8 design proposal of 1917, and was engineered to use a gear-driven supercharger. First run on 21 June 1922 initial performance was not as expected; as a result the stroke was increased to 5.5 in (139.7 mm) on all variants after the Jaguar I. Throughout its career the Jaguar suffered from vibration due to a lack of a crankshaft centre bearing. The most powerful version of the engine, the Jaguar VIC, produced a maximum of 490 hp (365 kW) on takeoff at 1,950 rpm and weighed 910 lb (413 kg). The later Lyn ...

Voluntary Liquidation
Liquidation is the process in accounting by which a company is brought to an end in Canada, United Kingdom, United States, Ireland, Australia, New Zealand, Italy, and many other countries. The assets and property of the company are redistributed. Liquidation is also sometimes referred to as winding-up or dissolution, although dissolution technically refers to the last stage of liquidation. The process of liquidation also arises when customs, an authority or agency in a country responsible for collecting and safeguarding customs duties, determines the final computation or ascertainment of the duties or drawback accruing on an entry. Liquidation may either be compulsory (sometimes referred to as a ''creditors' liquidation'' or ''receivership'' following bankruptcy, which may result in the court creating a "liquidation trust") or voluntary (sometimes referred to as a ''shareholders' liquidation'', although some voluntary liquidations are controlled by the creditors). The term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham Small Arms Company
The Birmingham Small Arms Company Limited (BSA) was a major British industrial combine, a group of businesses manufacturing military and sporting firearms; bicycles; motorcycles; cars; buses and bodies; steel; iron castings; hand tool, hand, power tool, power, and machine tool, machine tools; coal cleaning and handling plants; sintered metals; and hard chrome process. After the Second World War, BSA did not manage its business well, and a government-organised rescue operation in 1973 led to a takeover of such operations as it still owned. Those few that survived this process disappeared into the ownership of other businesses. History of the BSA industrial group Machine-made guns BSA began in June 1861 in the Gun Quarter, Birmingham, England. It was formed by a group of fourteen gunsmith members of the Birmingham Small Arms Trade Association specifically to manufacture guns by machinery. They were encouraged to do this by the War Office which gave the BSA gunsmiths free access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gnome Monosoupape
The ''Monosoupape'' ( French for single-valve), was a rotary engine design first introduced in 1913 by Gnome Engine Company (renamed Gnome et Rhône in 1915). It used a clever arrangement of internal transfer ports and a single pushrod-operated exhaust valve to replace the many moving parts found on more conventional rotary engines, and made the ''Monosoupape'' engines some of the most reliable of the era. British aircraft designer Thomas Sopwith described the ''Monosoupape'' as "one of the greatest single advances in aviation". Produced under license in both seven and nine-cylinder versions in large numbers in most industrialized countries including Germany (by Oberursel), Russia, Italy, Britain and the US. Two differing nine-cylinder versions were produced, the 9B-2 and 9N, with differing displacements giving the larger displacement 9N version a nearly-cylindrical shaped crankcase, with the 9N also adopting a dual ignition system for increased flight safety. 2,188 units wer ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallace Charles Devereux
Wallace Charles Devereux CBE (9 March 1893 – 21 June 1952) was a British businessman and engineer, known for his work in producing light alloys for the aircraft industry. Education He was born in Aston, now part of Birmingham, in 1893, then educated at Erdington High School. He then studied for three years at Birmingham School of Art, the subjects including machine design and metallurgy. First World War During the First World War, Devereux was appointed to the post of tool room superintendent of National Aircraft Factory No. 1. His study of airframe and engine design during this period, and in the years immediately following the war, convinced him of the possibilities of forged light alloys. Aircraft airframes, as well as engines, were now in a transitional phase and moving to the increased use of light alloys for construction, rather than wood or iron. Between the wars Following the end of the war he became works manager at Peter Hooker's where he began to realis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
