Jean-Jacques Meyer
Jean-Jacques Meyer (1805–1877) was a French engineer, noted for his work with steam engines and steam locomotives. Innovations Background He was trained at the engineering school Arts et Métiers ParisTech. Expansion valve His first major invention was the Meyer expansion valve, used to improve efficiency in stationary steam engines. The first locomotives to use this invention were a pair of 2-2-2 locomotives Mayer built for the in 1842. Named ''L'Espérance'' (Hope) and ''Le Succès'' (Success), they continued in service for S-B's successor, the Chemins de fer de l'Est until 1859. Articulated locomotive He was the originator of the articulated locomotives which bear his name. Meyer registered his first patent describing the system in 1861. The Meyer locomotive comprised: * a rigid single frame supporting cabin, and boiler; * two revolving units like bogies made up each one of a steam engine involving a group of driving wheels and possibly comprising carrying wheels. The fi ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Meyer Locomotive
A Meyer locomotive is a type of articulated locomotive. The design was never as popular as the Garratt or Mallet locomotives. It can be best regarded as 19th Century competition for the early compound Mallet and also the Fairlie articulated designs. Most single cab modern trains are of a similar design such as power cars, freight diesel locomotives, and some passenger locomotives. Development and design The Meyer was in fact invented by Austrian engineer Wenzel Günther of the Wiener Neustädter Lokomotivfabrik for the Semmering Trials of 1851. However, the technology wasn't yet developed for the steam to be reliably transported to the bogies with reasonable amount of leaks, and despite generally good performance of the design on the trials the company abandoned the idea. It was reinvigorated by Frenchman Jean-Jacques Meyer (1804-1877), who took out a patent on the design in 1861. The first locomotive, an named ''L'Avenir'' (Future), was built by in 1868 with the support of a ...

Locomotive Builders And Designers
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first u ...

Chemins De Fer De Ceinture De Paris
The Chemins Company is a dietary supplement manufacturer based in Colorado Springs, Colorado. The company, founded in 1974 by James Cameron, became embroiled in a series of criminal investigations in 1994 after a woman died and more than 100 other people became ill after taking one of the company’s products marketed under the brand name Nature's Nutrition Formula One. The adverse events were later linked to the product having been tainted with ephedrine. A three-year federal investigation, which revealed that the company had doctored records, misled FDA investigators, and purposely hindered inspections, led to Cameron being sentenced to 21 months in prison and him and the company being fined $4.7 million . The company also paid out $750,000 to settle a class action lawsuit alleging that the company's protein powder supplements contained approximately half the protein content and twice the carbohydrate content listed on the label. Chemins was the manufacturer of dietary supplements ...

Gaston du Bousquet (1839–1910) was a French engineer who was Chief of Motive Power () of the Chemin de Fer du Nord, designer of locomotives and professor at École centrale de Lille. Steam locomotive designer Gaston du Bousquet taught mechanical engineering at the Institut industriel du Nord de la France (École Centrale de Lille) from 1872. He was appointed chief engineer to the Chemins de Fer du Nord in 1890. He won a gold medal at the Universal Exhibition of 1894.

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Steam Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the f ...

Articulated Locomotive
An articulated locomotive is a steam locomotive (rarely, an electric locomotive) with one or more engine units that can move independent of the main frame. Articulation allows the operation of locomotives that would otherwise be too large to negotiate a railroad's curves, whether mainlines or special lines with extreme curvature such as logging, industrial, or mountain railways. Articulated locomotives saw service in many nations, but were very popular on narrow-gauge railways in Europe. The largest examples were developed in the United States, where the Union Pacific Big Boy 4-8-8-4s and the Allegheny H-8 2-6-6-6s were some of the largest steam locomotives ever built. Many schemes for articulation were developed over the years. Of these, the Mallet locomotive and its simple-expansion derivative were the most popular, followed by the Garratt type (mostly built in the United Kingdom, popular throughout Europe, Africa and European colonies), and the various geared steam locomot ...
