Writers To The Signet
The Society of Writers to His Majesty's Signet is a private society of Scottish solicitors, dating back to 1594 and part of the College of Justice. Writers to the Signet originally had special privileges in relation to the drawing up of documents required to be signeted, but these have since disappeared and the Society is now an independent, non-regulatory association of solicitors. The Society maintains the Category A listed Signet Library, part of the Parliament House complex in Edinburgh, and members of the Society are entitled to the postnominal letters WS. History Solicitors in Scotland were previously known as "writers"; Writers to the Signet were the solicitors entitled to supervise use of the King's Signet, the private seal of the early Kings of Scots. Records of that use date back to 1369. In 1532, the Writers to the Signet were included as Members in the newly established College of Justice, along with the Faculty of Advocates and the Clerks of the Court of Session. Th ...

Nicolas Léonard Sadi Carnot
''Sous-lieutenant'' Nicolas Léonard Sadi Carnot (; 1 June 1796 – 24 August 1832) was a French mechanical engineer in the French Army, military scientist and physicist, and often described as the "father of thermodynamics". He published only one book, the '' Reflections on the Motive Power of Fire'' (Paris, 1824), in which he expressed the first successful theory of the maximum efficiency of heat engines and laid the foundations of the new discipline: thermodynamics. Carnot's work attracted little attention during his lifetime, but it was later used by Rudolf Clausius and Lord Kelvin to formalize the second law of thermodynamics and define the concept of entropy. Based on purely technical concerns, such as improving the performance of the steam engine, Sadi Carnot's intellect laid the groundwork for modern science technological designs, such as the automobile or jet engine. His father Lazare Carnot was an eminent mathematician, military engineer, and leader of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Hearth Furnace
An open-hearth furnace or open hearth furnace is any of several kinds of industrial Industrial furnace, furnace in which excess carbon and other impurities are burnt out of pig iron to Steelmaking, produce steel. Because steel is difficult to manufacture owing to its high melting point, normal fuels and furnaces were insufficient for mass production of steel, and the open-hearth type of furnace was one of several technologies developed in the nineteenth century to overcome this difficulty. Compared with the Bessemer process, which it displaced, its main advantages were that it did not expose the steel to excessive nitrogen (which would cause the steel to become brittleness, brittle), was easier to control, and permitted the melting and refining of large amounts of scrap, scrap iron and steel. The open-hearth furnace was first developed by Germany, German-born engineer Carl Wilhelm Siemens. In 1865, the French engineer Pierre-Émile Martin took out a license from Siemens and first ...

George Richards Elkington
George Richards Elkington (17 October 1801 – 22 September 1865) was a manufacturer from Birmingham, England. He patented the first commercial electroplating process. Biography Elkington was born in Birmingham, the son of a spectacle manufacturer. Apprenticed to his uncles' silver plating business in 1815, he became, on their death, sole proprietor of the business, but subsequently took his cousin, Henry Elkington, into partnership. The science of electrometallurgy was then in its infancy, but the Elkingtons were quick to recognize its possibilities. They had already taken out certain patents for the application of electricity to metals when, in 1840, John Wright, a Birmingham surgeon, discovered the valuable properties of a solution of cyanide of silver in potassium cyanide for electroplating purposes. The Elkingtons purchased and patented Wright's process (British Patent 8447 : Improvements in Coating, Covering, or Plating certain Metals), subsequently acquiring the right ...
