Zuckerman Helmet
The Zuckerman helmet, officially designated the Civilian Protective Helmet, was a British helmet designed for use by civil defence organisations and the general public during World War II. It was researched and designed by Solly Zuckerman, Derman Christopherson and Hugh Cairns. Background Zuckerman and Cairns first started looking into a design for a helmet to aid civil defence in the mid-1940. Their aim was to provide a helmet that could deal with impact from falling and flying masonry and provide more coverage for the head and the neck areas. After the War Office accepted their design, the ''Civilian Protective Helmet'' went into circulation in December 1940 and throughout 1941, the vast majority therefore being dated 1941. Production Helmets were made from pressed mild steel or manganese steel (known for its impact resistance) in two sizes only and sometimes marked with either M (medium) or L (large) on the inside of the brim. The design of the high dome was to allow the helm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solly Zuckerman
Solomon "Solly" Zuckerman, Baron Zuckerman (30 May 1904 – 1 April 1993) was a British public servant, zoologist and operational research pioneer. He is best remembered as a scientific advisor to the Allies on bombing strategy in the Second World War, for his work to advance the cause of nuclear non-proliferation, and for his role in bringing attention to global economic issues.King, Stev"From boffin to baron", ''The Spectator'' (9 June 2001) Early life and education Solomon Zuckerman was born in Cape Town in the British Cape Colony (modern-day South Africa) on 30 May 1904, the second child and eldest son of Moses and Rebecca Zuckerman (née Glaser). Both his parents were the children of Jewish immigrants from the Russian Empire. He was educated at the South African College School. After studying medicine at the University of Cape Town and later attending Yale University, he went to London in 1926 to complete his studies at University College Hospital Medical School.

Derman Christopherson
Sir Derman Guy Christopherson (6 September 1915 – 7 November 2000) was a British engineering science academic. Early life and education Christopherson was born the son of a clergyman, Derman Christopherson (the vicar of Plumstead in southeast London), and Edith Frances Christopherson. Soon afterwards, the Christopherson family moved to Porlock in Devon, where his father was vicar of Clovelly. As a boy, Christopherson suffered from asthma. He was educated privately until, at age 14, he was sent to Sherborne School in Dorset. He gained a scholarship at University College, Oxford, initially to read Mathematics. Later, in 1937, he achieved a first class degree in Engineering Science. The following year he went to Harvard University in the United States as a Henry Fellow, gaining an SM master's degree in 1938. He returned to Oxford University as a research assistant to Sir Richard Southwell FRS, working on numerical methods for applied mechanics. He contributed to Southwell's ...

Hugh Cairns (surgeon)
Sir Hugh William Bell Cairns KBE FRCS (26 June 1896 – 18 July 1952) was an Australian neurosurgeon. For most of his life he lived in England. His concern about despatch rider injuries sparked research which led to increased use of motorcycle helmets. After one of his patients died, who was Lawrence of Arabia, he studied the positive effect the use of motorbike helmets had on reducing the severity of head injuries. Early years and education Hugh Cairns was born in Port Pirie, South Australia, but spent his early childhood in Riverton, South Australia where he received all of his primary school education. He went to Adelaide for his secondary education at Adelaide High School and tertiary education at the University of Adelaide. He was awarded the 1917 South Australian Rhodes Scholarship and went to the University of Oxford to read Medicine. He was president of the Balliol Boat Club and represented Oxford as bow in the Boat Race of 1920. Career Cairns worked as a neurosurgeon a ...

War Office
The War Office was a department of the British Government responsible for the administration of the British Army between 1857 and 1964, when its functions were transferred to the new Ministry of Defence (MoD). This article contains text from this source, which is available under th Open Government Licence v3.0 © Crown copyright It was equivalent to the Admiralty, responsible for the Royal Navy (RN), and (much later) the Air Ministry, which oversaw the Royal Air Force (RAF). The name 'War Office' is also given to the former home of the department, located at the junction of Horse Guards Avenue and Whitehall in central London. The landmark building was sold on 1 March 2016 by HM Government for more than £350 million, on a 250 year lease for conversion into a luxury hotel and residential apartments. Prior to 1855, 'War Office' signified the office of the Secretary at War. In the 17th and 18th centuries, a number of independent offices and individuals were re ...

Mild Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%. The term ''carbon steel'' may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many different uses such as milling machines, cutting tools (such as chisels) and high strength wires. These applications require a much finer microstructure, which improves the toughness. Carbon steel is a popular metal choic ...

Manganese Steel
Mangalloy, also called manganese steel or Hadfield steel, is an alloy steel containing an average of around 13% manganese. Mangalloy is known for its high impact strength and resistance to abrasion once in its work-hardened state. Material properties Mangalloy is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese. Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness. This allows mangalloy to retain its toughness. Most steels contain 0.15 to 0.8% manganese. High strength alloys often contain 1 to 1.8% manganese. At about 1.5% manganese content, the steel becomes brittle, and this trait increases until about 4 to 5% manganese content is reached. At this point, the steel will pulverize at the strike of a hammer. Further increase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austin Motors
The Austin Motor Company Limited was an English manufacturer of motor vehicles, founded in 1905 by Herbert Austin in Longbridge. In 1952 it was merged with Morris Motors Limited in the new holding company British Motor Corporation (BMC) Limited, keeping its separate identity. The marque Austin was used until 1987. The trademark is currently owned by the Chinese firm SAIC Motor, after being transferred from bankrupt subsidiary Nanjing Automotive which had acquired it with MG Rover Group in July 2005. History 1905–1918: Formation and development While running the original Wolseley business, which had a highly cyclical sales pattern, Herbert Austin searched for products with a steady demand. Starting in 1895, he built three cars in his free time. They were among Britain's first cars. The third car, a four-wheeler, was completed in 1899. By 1901 his fellow directors could not see future profit in motor vehicles and so with their blessing and the backing of the Vickers broth ...

Morris Motors
Morris Motors Limited was a British privately owned motor vehicle manufacturing company formed in 1919 to take over the assets of William Morris's WRM Motors Limited and continue production of the same vehicles. By 1926 its production represented 42 per cent of British car manufacture—a remarkable expansion rate attributed to William Morris's practice of buying in major as well as minor components and assembling them in his own factory. Self-financing through his enormous profits Morris did borrow some money from the public in 1926 and later shared some of Morris Motors' ownership with the public in 1936 when the new capital was used by Morris Motors to buy many of his other privately held businesses. Though it merged... although nearly twenty-five years had elapsed since the BMC merger, not even Austin and Morris, the two volume car manufacturers that formed the core of the original merger, had integrated to a significant degree.

Civil Defence Service
The Civil Defence Service was a civilian volunteer organisation in Great Britain during World War II. Established by the Home Office in 1935 as Air Raid Precautions (ARP), its name was officially changed to the Civil Defence Service (CD) in 1941. The Civil Defence Service included the Air Raid Precautions in the United Kingdom, ARP Wardens Service as well as firemen (initially the Auxiliary Fire Service (AFS) and latterly the National Fire Service (NFS)), fire watchers (later the Fire Guard), rescue, first aid post and stretcher parties. Over 1.9 million people served within the CD and nearly 2,400 lost their lives to enemy action. Organisation The organisation of Civil defense, civil defence was the responsibility of each local authority. Volunteers were ascribed to different units depending on experience or training. Each local civil defence service was divided into several sections. *Wardens were responsible for local reconnaissance and reporting, and leadership, organisation, ...

Combat Helmets Of The United Kingdom
Combat ( French for ''fight'') is a purposeful violent conflict meant to physically harm or kill the opposition. Combat may be armed (using weapons) or unarmed ( not using weapons). Combat is sometimes resorted to as a method of self-defense, or can be used as a tool to impose one's will on others. An instance of combat can be a stand-alone confrontation or a small part of a much larger violent conflict. Instances of combat may also be benign and recreational, as in the cases of combat sports and mock combat. Combat may comply with, or be in violation of local or international laws regarding conflict. Examples of rules include the Geneva Conventions (covering the treatment of people in war), medieval chivalry, the Marquess of Queensberry rules (covering boxing) and several forms of combat sports. Hand-to-hand combat Hand-to-hand combat (melee) is combat at very close range, attacking the opponent with the body ( striking, kicking, strangling, etc.) and/or with a melee wea ...
