- Metropolitan-Vickers Electrical Co LtdBiographyBiographyMetropolitan-Vickers Electrical Co Ltd was the new trading name given to British Westinghouse Electric and Manufacturing Co on 8 September 1919. The predecessor company had sold its controlling share to the Metropolitan Carriage Wagon Co in 1916 in order to gain membership of the Federation of British Industries. In 1919, Vickers acquired the Metropolitan Carriage Wagon Co, along with its controlling share in British Westinghouse, prompting the change in name to Metropolitan-Vickers Electrical Co Ltd. The American owned British Westinghouse had established its English operations at Trafford Park in 1899, and Metropolitan-Vickers Electrical Co Ltd continued on the same site from 8 September 1919. The company was initially known for its electricity generators, later diversifying into the manufacture of steam turbines, switchgear, transformers, electronics and railway traction equipment. The passing of the Electricity (Supply) Act in 1926 provided a boost to the company’s post-war fortunes, with the creation of the National Grid generating demand for the company's products. In 1928, Metropolitan-Vickers Electrical Co Ltd merged with its rival British Thomson Houston Co Ltd, retaining both names for trading purposes. The following year, on 4 January 1929, Associated Electrical Industries Ltd (AEI) acquired Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. Again, both trading names were retained, and a fierce rivalry was established between the firms which the parent company was unable to control. In 1931, Sir Felix Pole joined Metropolitan-Vickers Electrical Co Ltd as its new chairman. He oversaw a period of expansion for the company leading into the Second World War. In 1939, seeking a more concise name for the company, the Board of Directors decided upon Metrovicks, which became interchangeable with the official company name of Metropolitan-Vickers Electrical Co Ltd. Under Sir Felix Pole's chairmanship, Metropolitan-Vickers developed new products for the aviation industry and during the war was one of the sites where Lancaster bombers were built. In 1941, the company developed the first British axial-flow jet engine, the Metrovick F.2. Following the Second World War, the company appointed Oliver Lyttelton as chairman, with the aim of increasing the efficiency and productivity of AEI. Despite his success in achieving this aim, Lyttelton was unable to resolve the commercial rivalry between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. During his second period as chairman, from 1954-1963, Lyttelton, now Lord Chandos, oversaw the development by Metropolitan-Vickers Electrical Co Ltd of the first commercial transistor computer, the Metrovick 950. Chandos also resolved to extinguish the competition and internal divisions between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd, and both company names ceased to be used from 1 January 1960, with all subsidiaries going on to trade under the name of Associated Electrical Industries Ltd.

- Royal NavyBiographyBiographyThe Royal Navy (RN) is the United Kingdom's naval warfare force. It is the oldest of the UK’s armed services and is sometimes known as the Senior Service. It was formally established as the national naval force of England in 1660, following the restoration of King Charles II to the throne. Warships were however used by the English kings from the early medieval period, with the first major maritime engagements fought in the Hundred Years' War against France. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing the British Empire during the 19th and first part of the 20th centuries. Following World War I, the Royal Navy was significantly reduced in size, although at the onset of World War II it was still the world's largest. During the Cold War, the Royal Navy transformed into a primarily anti-submarine force, Following the collapse of the Soviet Union, its focus has returned to expeditionary operations around the world. However, 21st-century reductions in naval spending have led to a personnel shortage and a reduction in the number of warships. The Royal Navy is part of His Majesty's Naval Service, which also includes the Royal Marines. The professional head of the Naval Service is the First Sea Lord who is an admiral and member of the Defence Council of the United Kingdom. The Defence Council delegates management of the Naval Service to the Admiralty Board, chaired by the Secretary of State for Defence. The Royal Navy operates three bases in the United Kingdom where commissioned ships are based: Portsmouth, Clyde and Devonport, the last being the largest operational naval base in Western Europe.
- Royal Commission on Awards to InventorsBiographyBiographyA Royal Commission on Awards to Inventors is a periodic Royal Commission of the United Kingdom used to hear patent disputes. These inventions were broadly divided into two groups, patented and unpatented. Where an invention had been patented the inventor was legally protected. Although he or she could not control the use of his or her invention by the Government, or prevent the use of it at all, as was possible with private users, he or she was entitled to negotiate an equitable payment. The inventor of an unpatented device was not entitled by right to any payment for its use, but relied on the bounty of the Crown, exercised on the recommendation of the commission. A Royal Commission on Awards to Inventors was set up in 1919, which embraced consideration of all inventions used by the Government in the prosecution of the 1914-18 War. This wound up in 1937. Another was established in 1946 until 1955, this commission followed the general lines of that set up in 1919.
