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 Limited, Rolls-Royce ("RR") before World War II. They were manufactured and later developed by #High Duty Alloys Ltd., 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 luxury 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 Fascist Italy (1922–1943), Italian fascist politician and Blackshirts' leader who served as Italy's Marshal of the Air Force, Governor-General of Italian Libya and Commander-in-Chief of Italian North Africa. Due to his young age, he was sometimes seen as a possible successor to dictator Benito Mussolini. After serving in World War I, Balbo became the leading National Fascist Party, Fascist party organizer in his home region of Ferrara. He was one of the Quadrumvirs, 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 task of g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Siddeley Jaguar
The Armstrong Siddeley Jaguar is 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."World Encyclopedia of Aero Engines – 5th edition" by Bill Gunston, Sutton Publishing, 2006. p.13 Design and development The Jaguar was developed from the Royal Aircraft Factory RAF.8 design proposal of 1916. The RAF.8 was the work of a design team led by F.M. Green, and incorporated the findings of research into aluminium air-cooled cylinders by Samuel D. Heron and Professor A. H. Gibson. Disillusioned by political and press criticism of the Royal Air Factory, Green and his design team, including Heron, left the Factory in January 1917 and took up positions with the Siddeley-Deasy company. There they were req ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voluntary Liquidation
Liquidation is the process in accounting by which a Company (law), company is brought to an end. The assets and property of the business are redistributed. When a firm has been liquidated, it is sometimes referred to as :wikt:wind up#Noun, wound-up or dissolved, although Dissolution (law), dissolution technically refers to the last stage of liquidation. The process of liquidation also arises when customs, an authority or Government agency, agency in a country responsible for collecting and safeguarding Duty (economics), 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 sometimes a court can mandate the appointment of a liquidator e.g. ''wind-up order'' in Australia) or voluntary (sometimes referred to as a ''sharehold ...

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". Monosoupape engines were produced under license in large numbers in Britain, Russia, Italy 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 were produced under license in Britain, with an uprated version later built ...

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 realise the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
