John Dixon Gibbs
John Dixon Gibbs (1834–1912) was a British engineer and financier who, together with Lucien Gaulard, is often credited as the co-inventor of the AC step-down transformer. The transformer was first demonstrated in 1883 at London's Royal Aquarium. At the time the term "transformer" had not yet been invented, so instead it was referred to as a "secondary generator". Although he is usually credited equally with Gaulard, Gibb's role in the invention appears to have been more that of a financial backer and businessman. Although the underlying physics of the transformer, mainly Faraday's law of induction, had been known since the 1830s, transformers became viable only after the introduction of Gaulard and Gibbs's transformer design in 1883. The breakthrough was to build an iron transformer core which could act as a magnetic circuit. At the time, their invention was seen as overcomplicated since it contained a movable armature. It caught the attention of Sir Coutts Lindsay, who used it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucien Gaulard
Lucien Gaulard (16 July 1850 – 26 November 1888) invented devices for the Electricity distribution, transmission of alternating current electrical energy. Biography Gaulard was born in Paris, France in 1850. A power transformer developed by Gaulard of France and John Dixon Gibbs of England was demonstrated in London, and attracted the interest of George Westinghouse, Westinghouse. Gaulard and Gibbs first exhibited a device in London in 1881 and then sold the idea to the American company Westinghouse Electric Corporation, Westinghouse. They also exhibited the invention in Turin in 1884, where it was adopted for an electric lighting system. Many of the features of their design were adapted to the particular laws governing electrical distribution in the UK. In 1882, 1884, and 1885 Gaulard and Gibbs applied for patents on their transformer; however, these were overturned due to actions initiated by Sebastian Ziani de Ferranti and others. In 1885, William Stanley (physicist), Will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Royal Aquarium
The Royal Aquarium and Winter Garden was a place of amusement in Westminster, London. It opened in 1876, and the building was demolished in 1903. The attraction was located northwest of Westminster Abbey on Tothill Street. The building was designed by Alfred Bedborough in an ornamental style faced with Portland stone. The Aquarium Theatre was located in the west end of the building and was renamed the Imperial Theatre in 1879. Methodist Central Hall now occupies the site. History The Royal Aquarium opened on 22 January 1876. Its board of directors included Henry Labouchère, the financier and journalist; William Whiteley the retailer; and Arthur Sullivan, the composer. It was intended to offer art exhibitions, concerts and plays, among other intellectual entertainments such as The Crystal Palace.''The R ...

Faraday's Law Of Induction
Faraday's law of induction (briefly, Faraday's law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf)—a phenomenon known as electromagnetic induction. It is the fundamental operating principle of transformers, inductors, and many types of electrical motors, generators and solenoids. The Maxwell–Faraday equation (listed as one of Maxwell's equations) describes the fact that a spatially varying (and also possibly time-varying, depending on how a magnetic field varies in time) electric field always accompanies a time-varying magnetic field, while Faraday's law states that there is emf (electromotive force, defined as electromagnetic work done on a unit charge when it has traveled one round of a conductive loop) on the conductive loop when the magnetic flux through the surface enclosed by the loop varies in time. Faraday's law had been discovered and one aspect of it (transformer emf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir Coutts Lindsay
Sir Coutts Lindsay, 2nd Baronet (2 February 1824 – 7 May 1913 Kingston upon Thames), was a British artist and watercolourist. Life Lindsay was the eldest son of Lieutenant-General James Lindsay (1793-1855), Sir James Lindsay, son of the Hon. Robert Lindsay, second son of James Lindsay, 5th Earl of Balcarres. His mother was Anne, daughter of Sir Coutts Trotter, 1st Baronet, a principal partner in Coutts, Coutt's Bank. Robert Loyd-Lindsay, 1st Baron Wantage, was his younger brother. In 1839 he succeeded by special remainder to his maternal grandfather's baronetcy (which became extinct on Lindsay's own death). He then entered the army, commanding the 1st Regiment of the Italian Legion during the Crimean War before retiring from military life to devote himself to art. From 1862 to 1874 he exhibited many pictures, including various successful portraits. In 1879 he and his first wife, Lady Lindsay (of Balcarres), were both elected to membership of the Royal Institute of Painters ...

Grosvenor Gallery
The Grosvenor Gallery was an art gallery in London founded in 1877 by Sir Coutts Lindsay and his wife Blanche. Its first directors were J. Comyns Carr and Charles Hallé. The gallery proved crucial to the Aesthetic Movement because it provided a home for those artists whose approaches the more classical and conservative Royal Academy did not welcome, such as Edward Burne-Jones and Walter Crane. History The gallery was founded in Bond Street, London, in 1877 by Sir Coutts Lindsay and his wife Blanche. They engaged J. Comyns Carr and Charles Hallé as co-directors. Lindsay and his wife were well-born and well-connected, and both were amateur artists. Blanche was born a Rothschild, and it was her money which made the whole enterprise possible. The Grosvenor displayed work by artists from outside the British mainstream, including Edward Burne-Jones, Walter Crane and other members of the Pre-Raphaelite Brotherhood. But it also featured work by others that were widely shown elsew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ottó Bláthy
Ottó Titusz Bláthy (11 August 1860 – 26 September 1939) was a Hungarian electrical engineer. In his career, he became the co-inventor of the modern electric transformer, the tension regulator, the AC watt-hour meter. motor capacitor for the single-phase (AC) electric motor, the turbo generator, and the high-efficiency turbo generator. Bláthy's career as an inventor began during his time at the Ganz Works in 1883. There, he conducted experiments for creating a transformer. The name "transformer" was created by Bláthy. In 1885 the ''ZBD'' model alternating-current transformer was invented by three Hungarian engineers: Ottó Bláthy, Miksa Déri and Károly Zipernowsky. (''ZBD'' comes from the initials of their names). In the autumn of 1889 he patented the AC watt-meter. Student paper read on 24 January 1896 at the Students' Meeting. Early life He attended schools in Tata and Vienna, where he obtained diploma of machinery in 1882. Between 1881 and 1883 he worked at ...

Miksa Déri
Miksa Déri (27 October 1854 November, Bács, Kingdom of Hungary, (now: Bač, Serbia) – 3 March 1938) was a Hungarian electrical engineer, inventor, power plant builder. He contributed with his partners Károly Zipernowsky and Ottó Bláthy, in the development of the closed iron core transformer and the ZBD model. His other important invention was the constant voltage AC electrical generator in the Ganz Works in 1883. The missing link of a full Voltage sensitive - voltage intensive (VSVI) system was the reliable AC Constant Voltage generator. Therefore, the invention of the constant voltage generator at the Ganz Works had crucial role in the beginnings of the industrial scale AC power generating, because only these type of generators can produce a stated output voltage, regardless of the value of the actual load. ZBD was an abbreviation of the three men's names: Zipernowsky, Bláthy and Déri. Déri is also noted for inventing the single phase type of repulsion motor ...

Károly Zipernowsky
Károly Zipernowsky (born as Carl Zipernowsky, 4 April 1853 in Vienna – 29 November 1942 in Budapest) was an Austrian Empire, Austrian-born Hungarians, Hungarian electrical engineer. He invented the transformer with his colleagues (Miksa Déri and Ottó Bláthy) at the famous Kingdom of Hungary, Hungarian manufacturing company Ganz Works and he contributed significantly with his works also to other Alternating current, AC technologies. Biography Zipernowsky, with Ottó Bláthy and Miksa Déri, all of Ganz and Company, were researching ways of increasing efficiency of electrical power transmission. They experimented with power supplies and current transformation, which led to the invention of the ZBD alternating current transformer in 1885. The ZBD system is based on a closed-iron ring core with an arbitrary diameter and a coil around the core, which conducts Alternating current, AC current. Their system converted higher voltage suitable for energy transmission to lower "' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Westinghouse
George Westinghouse Jr. (October 6, 1846 – March 12, 1914) was an American entrepreneur and engineer based in Pennsylvania who created the railway air brake and was a pioneer of the electrical industry, receiving his first patent at the age of 19. Westinghouse saw the potential of using alternating current for electric power distribution in the early 1880s and put all his resources into developing and marketing it. This put Westinghouse's business in direct competition with Thomas Edison, who marketed direct current for electric power distribution. In 1911 Westinghouse received the American Institute of Electrical Engineers's (AIEE) Edison Medal "For meritorious achievement in connection with the development of the alternating current system." Early years George Westinghouse was born in 1846 in Central Bridge, New York (see George Westinghouse Jr. Birthplace and Boyhood Home), the son of Emeline (Vedder) and George Westinghouse Sr., a machine shop owner. His ancestors came fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
