Henry Wilde (engineer)
Henry Wilde (1833 – 28 March 1919) was a wealthy individual from Manchester, England who used his self-made fortune to indulge his interest in electrical engineering. Wilde invented the dynamo-electric machine, or self-energising dynamo, an invention for which Werner von Siemens is more usually credited and, in fact, discovered independently. At any rate, Wilde was the first to publish, his paper was communicated to the Royal Society by Michael Faraday in 1866.Cardwell, p218. The self-energising dynamo replaces the permanent magnets of previous designs with electro-magnets and in so doing achieved an enormous increase in power. The machine was considered remarkable at the time, especially since Wilde was fond of spectacular demonstrations, such as the ability of his machine to cause iron bars to melt. Academic patronage Wilde joined the Manchester Literary and Philosophical Society in 1859 and was President 1894-1896. He made many gifts and endowments to further the cau ...

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...

Edward Schunck
Henry Edward Schunck (16 August 1820 – 13 January 1903), also known as Edward von Schunck, was a British chemist who did much work with dyes. Early life and education Henry Edward Schunck was born in Manchester, the son of Martin Schunck, a German merchant. His grandfather was Major Johann-Carl Schunck (1745–1800). Edward started studying chemistry in Manchester with William Henry. The young Schunck was sent to further his chemical studies to Berlin where he studied under Heinrich Rose (1795–1864) who discovered niobium, diligently analysed minerals and other inorganic substances and studied the chemistry of titanium, phosphorus, arsenic, antimony, sulphur, selenium and tellurium. Schunck also studied at Berlin under Heinrich Gustav Magnus (1802–1870) who published over 80 papers on many diverse topics in chemistry and physics. After studying in Berlin he received his PhD under Justus Liebig at the University of Gießen. Work It was from Gießen that in 1841 he publi ...

Arthur Schuster
Sir Franz Arthur Friedrich Schuster (12 September 1851 – 14 October 1934) was a German-born British physicist known for his work in spectroscopy, electrochemistry, optics, X-radiography and the application of harmonic analysis to physics. Schuster's integral is named after him. He contributed to making the University of Manchester a centre for the study of physics. Early years Arthur Schuster was born in Frankfurt am Main, Germany the son of Francis Joseph Schuster, a cotton merchant and banker, and his wife Marie Pfeiffer. Schuster's parents were married in 1849, converted from Judaism to Christianity, and brought up their children in that faith. In 1869, his father moved to Manchester where the family textile business was based. Arthur, who had been to school in Frankfurt and was studying in Geneva, joined his parents in 1870 and he and the other children became British citizens in 1875. Edgar Schuster (1897–1969) was his nephew. From his childhood, Schuster had been i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrolyte
An electrolyte is a medium containing ions that is electrically conducting through the movement of those ions, but not conducting electrons. This includes most soluble salts, acids, and bases dissolved in a polar solvent, such as water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, the term electrolyte refers to the substance that is dissolved. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. Some gases, such as hydrogen chloride (HCl), under conditions of high temperature or low pressure can also function as electrolytes. El ...

Albert Medal (RSA)
The Albert Medal of the Royal Society of Arts (RSA) was instituted in 1864 as a memorial to Prince Albert, who had been President of the Society for 18 years. It was first awarded in 1864 for "distinguished merit in promoting Arts, Manufactures and Commerce". In presenting the Medal, the Society now looks to acknowledge individuals, organizations and groups that lead progress and create positive change within contemporary society in areas that are linked closely to the Society's broad agenda. Through the Albert Medal, the Society acknowledges the creativity and innovation of those that work to tackle some of the world's intractable problems. Each year, the RSA identifies issues by asking the Society's Fellowship to suggest problems and subjects linked to the Society's programme. These proposals are reviewed and recommendations made to the Trustees and Council, who are responsible for selecting one upon which the Fellowship will be asked to nominate worthy recipients.

Golding Bird
Golding Bird (9 December 1814 – 27 October 1854) was a British medical doctor and a Fellow of the Royal College of Physicians. He became a great authority on kidney diseases and published a comprehensive paper on urinary deposits in 1844. He was also notable for his work in related sciences, especially the medical uses of electricity and electrochemistry. From 1836, he lectured at Guy's Hospital, a well-known teaching hospital in London and now part of King's College London, and published a popular textbook on science for medical students called ''Elements of Natural Philosophy''. Having developed an interest in chemistry while still a child, largely through self-study, Bird was far enough advanced to deliver lectures to his fellow pupils at school. He later applied this knowledge to medicine and did much research on the chemistry of urine and of kidney stones. In 1842, he was the first to describe oxaluria, a condition which leads to the formation of a particul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.

Electro-plating
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current. The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material. The current is provided by an external power supply. Electroplating is widely used in industry and decorative arts to improve the surface qualities of objects—such as resistance to abrasion (mechanical), abrasion and corrosion, lubricity, reflectivity, electrical conductivity, or appearance. It is used to build up thickness on undersized or worn-out parts, or to manufacture metal plates with complex shape, a process called electroforming. It is used to deposit copper and other conducto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
