45 Brennan, Louis
[br]b. 28 January 1852 Castlebar, Irelandd. 17 January 1932 Montreux, Switzerland[br]Irish inventor of the Brennan dirigible torpedo, and of a gyroscopically balanced monorail system.[br]The Brennan family, including Louis, emigrated to Australia in 1861. He was an inventive genius from childhood, and while at Melbourne invented his torpedo. Within it were two drums, each with several miles of steel wire coiled upon it and mounted on one of two concentric propeller shafts. The propellers revolved in opposite directions. Wires were led out of the torpedo to winding drums on land, driven by high-speed steam engines: the faster the drums on shore were driven, the quicker the wires were withdrawn from the drums within the torpedo and the quicker the propellers turned. A steering device was operated by altering the speeds of the wires relative to one another. As finally developed, Brennan torpedoes were accurate over a range of 1 1/2 miles (2.4 km), in contrast to contemporary self-propelled torpedoes, which were unreliable at ranges over 400 yards (366 in).Brennan moved to England in 1880 and sold the rights to his torpedo to the British Government for a total of £110,000, probably the highest payment ever made by it to an individual inventor. Brennan torpedoes became part of the defences of many vital naval ports, but never saw active service: improvement of other means of defence meant they were withdrawn in 1906. By then Brennan was deeply involved in the development of his monorail. The need for a simple and cheap form of railway had been apparent to him when in Australia and he considered it could be met by a ground-level monorail upon which vehicles would be balanced by gyroscopes. After overcoming many manufacturing difficulties, he demonstrated first a one-eighth scale version and then a full-size, electrically driven vehicle, which ran on its single rail throughout the summer of 1910 in London, carrying up to fifty passengers at a time. Development had been supported financially by, successively, the War Office, the India Office and the Government of the Indian state of Jammu and Kashmir, which had no rail access; despite all this, however, no further financial support, government or commercial, was forthcoming.Brennan made many other inventions, worked on the early development of helicopters and in 1929 built a gyroscopically balanced, two-wheeled motor car which, however, never went into production.[br]Principal Honours and DistinctionsCompanion of the Bath 1892.Bibliography1878, British patent no. 3359 (torpedo) 1903, British patent no. 27212 (stability mechanisms).Further ReadingR.E.Wilkes, 1973, Louis Brennan CB, 2 parts, Gillingham (Kent) Public Library.

46 Crampton, Thomas Russell
[br]b. 6 August 1816 Broadstairs, Kent, Englandd. 19 April 1888 London, England[br]English engineer, pioneer of submarine electric telegraphy and inventor of the Crampton locomotive.[br]After private education and an engineering apprenticeship, Crampton worked under Marc Brunel, Daniel Gooch and the Rennie brothers before setting up as a civil engineer in 1848. His developing ideas on locomotive design were expressed through a series of five patents taken out between 1842 and 1849, each making a multiplicity of claims. The most typical feature of the Crampton locomotive, however, was a single pair of driving wheels set to the rear of the firebox. This meant they could be of large diameter, while the centre of gravity of the locomotive remained low, for the boiler barrel, though large, had only small carrying-wheels beneath it. The cylinders were approximately midway along the boiler and were outside the frames, as was the valve gear. The result was a steady-riding locomotive which neither pitched about a central driving axle nor hunted from side to side, as did other contemporary locomotives, and its working parts were unusually accessible for maintenance. However, adhesive weight was limited and the long wheelbase tended to damage track. Locomotives of this type were soon superseded on British railways, although they lasted much longer in Germany and France. Locomotives built to the later patents incorporated a long, coupled wheelbase with drive through an intermediate crankshaft, but they mostly had only short lives. In 1851 Crampton, with associates, laid the first successful submarine electric telegraph cable. The previous year the brothers Jacob and John Brett had laid a cable, comprising a copper wire insulated with gutta-percha, beneath the English Channel from Dover to Cap Gris Nez: signals were passed but within a few hours the cable failed. Crampton joined the Bretts' company, put up half the capital needed for another attempt, and designed a much stronger cable. Four gutta-percha-insulated copper wires were twisted together, surrounded by tarred hemp and armoured by galvanized iron wires; this cable was successful.Crampton was also active in railway civil engineering and in water and gas engineering, and c. 1882 he invented a hydraulic tunnel-boring machine intended for a Channel tunnel.[br]Principal Honours and DistinctionsVice-President, Institution of Mechanical Engineers.

47 Haynes, Elwood
[br]b. 14 October 1857 Portland, Indiana, USAd. 13 April 1925 Kokomo, Indiana, USA[br]American inventor ofStellite cobalt-based alloys, early motor-car manufacturer and pioneer in stainless steels.[br]From his early years, Haynes was a practising Presbyterian and an active prohibitionist. He graduated in 1881 at Worcester, Massachusetts, and a spell of teaching in his home town was interrupted in 1884–5 while he attended the Johns Hopkins University in Baltimore. In 1886 he became permanently diverted by the discovery of natural gas in Portland. He was soon appointed Superintendent of the local gas undertaking, and then in 1890 he was hired by the Indiana Natural Gas \& Oil Company. While continuing his gas-company employment until 1901, Haynes conducted numerous metallurgical experiments. He also designed an automobile: this led to the establishment of the Haynes- Apperson Company at Kokomo as one of the earliest motor-car makers in North America. From 1905 the firm traded as the Haynes Automobile Company, and before its bankruptcy in 1924 it produced more than 50,000 cars. After 1905, Haynes found the first "Stellite" alloys of cobalt and chromium, and in 1910 he was publicizing the patented material. He then discovered the valuable hardening effect of tungsten, and in 1912 began applying the "improved" Stellite to cutting tools. Three years later, the Haynes Stellite Company was incorporated, with Haynes as President, to work the patents. It was largely from this source that Haynes became a millionaire in 1920. In April 1912, Haynes's attempt to patent the use of chromium with iron to render the product rustless was unsuccessful. However, he re-applied for a US patent on 12 March 1915 and, although this was initially rejected, he persevered and finally obtained recognition of his modified claim. The American Stainless Steel Company licensed the patents of Brearley and Haynes jointly in the USA until the 1930s.[br]Principal Honours and DistinctionsJohn Scott Medal 1919 (awarded for useful inventions).BibliographyHaynes was the author of more than twenty published papers and articles, among them: 1907, "Materials for automobiles", Proceedings of the American Society of MechanicalEngineers 29:1,597–606; 1910, "Alloys of nickel and cobalt with chromium", Journal of Industrial Engineeringand Chemistry 2:397–401; 1912–13, "Alloys of cobalt with chromium and other metals", Transactions of the American Institute of 'Mining Engineers 44:249–55;1919–20, "Stellite and stainless steel", Proceedings of the Engineering Society of WestPennsylvania 35:467–74.1 April 1919, US patent no. 1,299,404 (stainless steel).The four US patents worked by the Haynes Stellite Company were: 17 December 1907, patent no. 873,745.1 April 1913, patent no. 1,057,423.1 April 1913, patent no. 1,057, 828.17 August 1915, patent no. 1,150, 113.Further ReadingR.D.Gray, 1979, Alloys and Automobiles.

48 Ma Jun (Ma Chun)
[br]fl. 220–265 China[br]Chinese engineer and inventor.[br]Ma Jun was active at the court of Emperor Ming Ti and achieved several useful inventions in a number of fields. First, he made improvements in the silk-weaving loom by simplifying the heddles and treadles, thereby enabling a greater variety of patterns to be woven. Second, he constructed a "south pointing carriage", which was a two-wheeled cart with a train of gears arranged so that whichever direction the vehicle turned, the figure mounted on top of it would always point south. This may seem trivial, but the carriage may have had useful applications, possibly in surveying. During the period 227 to 239, Ma Jun also made a square-pallet chain pump, usually attributed to Bi Lan (186 AD), Loyang, that was used to irrigate parks and gardens. Other inventions included rotary ballistae and mechanical toys that were worked by water power, such as puppets operated by horizontal jack wheels.[br]Further ReadingJ.Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1965, Vol. IV, 2, pp. 39–42, 286–8, 295, 303, 346, 350, 524, 532–3.LRD -
49 Moulton, Alexander
[br]b. 9 April 1920 Stratford-on-Avon[br]English inventor of vehicle suspension systems and the Moulton bicycle.[br]He spent his childhood at The Hall in Bradfordon-Avon. He was educated at Marlborough College, and in 1937 was apprenticed to the Sentinel Steam Wagon Company of Shrewsbury. About that same time he went to King's College, Cambridge, where he took the Mechanical Sciences Tripos. It was then wartime, and he did research on aero-engines at the Bristol Aeroplane Company, where he became Personal Assistant to Sir Roy Fedden. He left Bristol's in 1945 to join his family firm, Spencer \& Moulton, of which he eventually became Technical Director and built up the Research Department. In 1948 he invented his first suspension unit, the "Flexitor", in which an inner shaft and an outer shell were separated by an annular rubber body which was bonded to both.In 1848 his great-grandfather had founded the family firm in an old woollen mill, to manufacture vulcanized rubber products under Charles Goodyear's patent. The firm remained a family business with Spencer's, consultants in railway engineering, until 1956 when it was sold to the Avon Rubber Company. He then formed Moulton Developments to continue his work on vehicle suspensions in the stables attached to The Hall. Sponsored by the British Motor Corporation (BMC) and the Dunlop Rubber Company, he invented a rubber cone spring in 1951 which was later used in the BMC Mini (see Issigonis, Sir Alexander Arnold Constantine): by 1994 over 4 million Minis had been fitted with these springs, made by Dunlop. In 1954 he patented the Hydrolastic suspension system, in which all four wheels were independently sprung with combined rubber springs and damper assembly, the weight being supported by fluid under pressure, and the wheels on each side being interconnected, front to rear. In 1962 he formed Moulton Bicycles Ltd, having designed an improved bicycle system for adult use. The conventional bicycle frame was replaced by a flat-sided oval steel tube F-frame on a novel rubber front and rear suspension, with the wheel size reduced to 41 cm (16 in.) with high-pressure tyres. Raleigh Industries Ltd having refused his offer to produce the Moulton Bicycle under licence, he set up his own factory on his estate, producing 25,000 bicycles between 1963 and 1966. In 1967 he sold out to Raleigh and set up as Bicycle Consultants Ltd while continuing the suspension development of Moulton Developments Ltd. In the 1970s the combined firms employed some forty staff, nearly 50 per cent of whom were graduates.He won the Queen's Award for Industry in 1967 for technical innovation in Hydrolastic car suspension and the Moulton Bicycle. Since that time he has continued his innovative work on suspensions and the bicycle. In 1983 he introduced the AM bicycle series of very sophisticated space-frame design with suspension and 43 cm (17 in.) wheels; this machine holds the world speed record fully formed at 82 km/h (51 mph). The current Rover 100 and MGF use his Hydragas interconnected suspension. By 1994 over 7 million cars had been fitted with Moulton suspensions. He has won many design awards and prizes, and has been awarded three honorary doctorates of engineering. He is active in engineering and design education.[br]Principal Honours and DistinctionsQueen's Award for Industry 1967; CBE; RDI.

50 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -
51 Stevenson, Robert
[br]b. 8 June 1772 Glasgow, Scotlandd. 12 July 1850 Edinburgh, Scotland[br]Scottish lighthouse designer and builder.[br]After his father's death when he was only 2 years old, Robert Stevenson was educated at a school for children from families in reduced circumstances. However, c. 1788 his mother married again, to Thomas Smith, Engineer to the Northern Lighthouse Board. Stevenson then served an apprenticeship under his new stepfather. The Board, which is still an active force in the 1990s, was founded in 1786 to oversee the lights and buoyage in some of the wildest waters in Western Europe, the seas around the coasts of Scotland and the Isle of Man.After studies at Andersen's College (now the University of Strathclyde) and later at Edinburgh University, Stevenson assumed responsibility in the field for much of the construction work sanctioned by the Board. After some years he succeeded Smith as Engineer to the Board and thereby the long connection between the Northern Lights and the Stevenson family commenced.Stevenson became Engineer to the Board when he was about 30 years old, remaining in that office for the best part of half a century. During these years he improved catoptric lighting, adopted the central lamp refracting system and invented the intermittent flashing light. While these developments were sufficient to form a just memorial to the man, he was involved in greater endeavours in the construction of around twenty lighthouses, most of which had ingenious forms of construction. The finest piece was the Bell Rock Lighthouse, built on a reef off the Scottish East Coast. This enterprise took five years to complete and can be regarded as the most important construction of his life.His interests fitted in with those of the other great men living in and around Edinburgh at the time, and included oceanography, astronomy, architecture and antiquarian studies. He designed several notable bridges, proposed a design for the rails for railways and also made a notable study of marine timber borers. He contributed to Encyclopaedia Britannica and to many journals.His grandson, born in the year of his death, was the famous author Robert Louis Stevenson (1850–94).[br]Principal Honours and DistinctionsFRS Edinburgh.Further ReadingSir Walter Scott, 1982, Northern Lights, Hawick.FMW -

Reactive energy management
In electrical networks, reactive energy results in increased line currents for a given active energy transmitted to loads.
The main consequences are:
• Need for oversizing of transmission and distribution networks by utilities,
• Increased voltage drops and sags along the distribution lines,
• Additional power losses.
This results in increased electricity bills for industrial customers because of:• Penalties applied by most utilities on reactive energy,
• Increased overall kVA demand,
• Increased energy consumption within the installations.
Reactive energy management aims to optimize your electrical installation by reducing energy consumption, and to improve power availability.
Total CO2 emissions are also reduced.
Utility power bills are typically reduced by 5 % to 10 %.
[Schneider Electric]Компенсация реактивной мощности
Передача по электрической сети реактивной энергии приводит к увеличению линейных токов (по сравнению токами, протекающими при передаче нагрузкам только активной энергии).
Основные последствия этого явления:
● необходимость увеличения сечения проводников в сетях передачи и распределения электроэнергии;
● повышенное падение и провалы напряжения в распределительных линиях;
● дополнительные потери электроэнергии;
Для промышленных потребителей такие потери приводят к возрастанию расходов на оплату электроэнергии, что вызвано:● штрафами, накладываемыми поставщиками электроэнергии за избыточную реактивную мощность;
● увеличением потребления полной мощности (измеряемой в кВА);
● повышенным энергопотреблением электроустановок.Цель компенсации реактивной мощности (КРМ) – оптимизация работы электроустановки за счет сокращения потребления энергии и увеличения надежности электроснабжения. Кроме того, КРМ позволяет уменьшить выбросы CO2 и сократить расходы на электроэнергию в среднем на 5-10 %.
[Перевод Интент]Наиболее эффективным способом снижения потребляемой из сети реактивной мощности является применение установок компенсации реактивной мощности (конденсаторных установок).
Использование конденсаторных установок позволяет:- разгрузить питающие линии электропередачи, трансформаторы и распределительные устройства;
- снизить расходы на оплату электроэнергии;
- при использовании определенного типа установок снизить уровень высших гармоник;
- подавить сетевые помехи, снизить несимметрию фаз;
- увеличить надежность и экономичность распределительных сетей.
На практике коэффициент мощности после компенсации находится в пределах от 0,93 до 0,99.
Наибольший экономический эффект достигается при размещении компенсирующих устройств вблизи электроприемников, потребляющих реактивную мощность.
Различают следующие виды компенсации:-
индивидуальная (нерегулируемая) компенсация
Целесообразна, если мощность электроприемника больше 20 кВт и потребляемая мощность постоянна в течение длительного времени.
Компенсирующая нерегулируемая установка подключается непосредственно у потребителя. Как правило, применяется для компенсации реактивной мощности таких потребителей, как мощные компрессоры, вентиляторы и насосы, силовые трансформаторы. - групповая (нерегулируемая) компенсация
- централизованная компенсация
Для ламп типа ДРЛ, ДРИ, ДРИЗ, ДНаТ может применяться как групповая, так и индивидуальная компенсация реактивной мощности
