Joseph Farcot
Jean Joseph Léon Farcot (23 June 1824 – 19 March 1908) was a French engineer and industrialist whose factories employed up to 700 workers. He was also a prolific inventor. He was one of the pioneers of the servomechanism, where a feedback loop helps control a machine. The invention lets one helmsman control a ship's rudder weighing several tons. Life Jean Joseph Léon Farcot was born in Paris on 23 June 1824. He was the son of the engineer Marie-Joseph Farcot (1798–1875). His grandfather was the learned economist and philanthropist Joseph Jean Chrysostome Farcot (1744–1815). At first he was interested in history, but then decided to join the family business. He obtained a diploma in 1845 from the Central School of Arts and Manufactures in Paris. He then joined the family firm. In 1846 Marie-Joseph Farcot transferred his factory close to the docks and railway station in Saint-Ouen on the Seine. Through successive purchases of land the works grew to almost .

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Hunting Oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system "hunts" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering. Railway wheelsets A classical hunting oscillation is a swaying motion of a railway vehicle (often called ''truck hunting'' or ''bogie hunting'') caused by the coning action on which the directional stability of an adhesion railway depends. It arises from the interaction of adhesion forces and inertial forces. At low speed, adhesion dominates but, as the speed increases, the adhesion forces and inertial forces become comparable in magnitude and the oscillation begins at a critical speed. Above this speed, the motion can be violent, damaging track and wheels and potentially causing derailment. The problem does not occur on systems with a differential because the action dep ...

Cybernetics
Cybernetics is a wide-ranging field concerned with circular causality, such as feedback, in regulatory and purposive systems. Cybernetics is named after an example of circular causal feedback, that of steering a ship, where the helmsperson maintains a steady course in a changing environment by adjusting their steering in continual response to the effect it is observed as having. Cybernetics is concerned with circular causal processes such as steering however they are embodied,Ashby, W. R. (1956). An introduction to cybernetics. London: Chapman & Hall, p. 1. including in ecological, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, conversation, and the practice of cybernetics itself. Cybernetics' transdisciplinary and "antidisciplinary" character has meant that it intersects with a number of other fields, leading to it having both wide influence and diverse interpretations.

John McFarlane Gray
John McFarlane Gray (7 April 1831 – 14 January 1908), also known as J. Macfarlane Gray, was a Scottish engineer who invented a portable steam riveting machine and a steam steering mechanism for Isambard Kingdom Brunel's famous ''SS Great Eastern''. Early years John Macfarlane Gray was born on 7 April 1831 in Kincardine, Scotland. His father was a draper. McFarlane Gray had no interest in following his father's trade. He left home and moved to Edinburgh where he worked as an apprentice while studying the Hebrew and Greek languages, mathematics and mechanics. He then moved to Paisley where he worked for Mr. Blackwood, later a partner in Blackwood and Gordon. He next obtained a position with McNab's marine engineering works in Greenock. Here he worked as an engineer, and was rapidly promoted. Gray returned to Blackwood and Gordon's, which had now moved to Port Glasgow. His employers recommended him for a position as chief draftsman and manager at the George Forrester and Compa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exposition Universelle (1878)
The third Paris World's Fair, called an Exposition Universelle in French, was held from 1 May to 10 November 1878. It celebrated the recovery of France after the 1870–71 Franco-Prussian War. Construction The buildings and the fairgrounds were somewhat unfinished on opening day, as political complications had prevented the French government from paying much attention to the exhibition until six months before it was due to open. However, efforts made in April were prodigious, and by 1 June, a month after the formal opening, the exhibition was finally completed. This exposition was on a far larger scale than any previously held anywhere in the world. It covered over , the main building in the Champ de Mars and the hill of Chaillot, occupying . The Gare du Champ de Mars was rebuilt with four tracks to receive rail traffic occasioned by the exposition. The Pont d'Iéna linked the two exhibition sites along the central allée. The French exhibits filled one-half of the entir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corliss Steam Engine
A Corliss steam engine (or Corliss engine) is a steam engine, fitted with rotary valves and with variable valve timing patented in 1849, invented by and named after the American engineer George Henry Corliss of Providence, Rhode Island. Engines fitted with Corliss valve gear offered the best thermal efficiency of any type of stationary steam engine until the refinement of the uniflow steam engine and steam turbine in the 20th century. Corliss engines were generally about 30 percent more fuel efficient than conventional steam engines with fixed cutoff. This increased efficiency made steam power more economical than water power, allowing industrial development away from millponds. Corliss engines were typically used as stationary engines to provide mechanical power to line shafting in factories and mills and to drive dynamos to generate electricity. Many were quite large, standing many metres tall and developing several hundred horsepower, albeit at low speed, turning massive fly ...

Joseph Farcot Governor For Corliss Engine 1878
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages. This spelling is also found as a variant in the languages of the modern-day Nordic countries. In Portuguese and Spanish, the name is "José". In Arabic, including in the Quran, the name is spelled '' Yūsuf''. In Persian, the name is "Yousef". The name has enjoyed significant popularity in its many forms in numerous countries, and ''Joseph'' was one of the two names, along with ''Robert'', to have remained in the top 10 boys' names list in the US from 1925 to 1972. It is especially common in contemporary Israel, as either "Yossi" or "Yossef", and in Italy, where the name "Giuseppe" was the most common male name in the 20th century. In the first century CE, Joseph was the second most popular male name for Palestine Jews. In the Book of Genesis Joseph is Jacob's eleventh son and Rachel's first son, and k ...

Governor (device)
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
