Georges Claude
Georges Claude (24 September 187023 May 1960) was a French engineer and inventor. He is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. He has been considered by some to be "the Edison of France". Claude was an active collaborator with the German occupiers of France during the Second World War, for which he was imprisoned in 1945 and stripped of his honors. Early life and career Georges Claude was born on 24 September 1870 in Paris, France, during the city's siege by German forces. Georges Claude studied at the École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). He then held several positions. He was an electrical inspector in a cable factory and the laboratory manager in an electric works. He founded and edited a magazine, ''L'Étincelle Électrique'' (''The Electric Spark'') ...

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.

Liquefaction Of Gases
Liquefaction of gases is physical conversion of a gas into a liquid state ( condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders. Uses Liquefaction processes are used for scientific, industrial and commercial purposes. Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG, and in refrigeration and air conditioning. There the gas is liquefied in the '' condenser'', where the heat of vaporization is released, and evaporated in the ''evaporator,'' where the heat of vaporization is absorbed. Ammonia was the first such refrigerant, and is still in widespread use in industrial refrigeration, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Packard
Packard or Packard Motor Car Company was an American luxury automobile company located in Detroit, Michigan. The first Packard automobiles were produced in 1899, and the last Packards were built in South Bend, Indiana in 1958. One of the "Three Ps" alongside Peerless Motor Company, and Pierce-Arrowthe company was known for building high-quality luxury automobiles before World War II. Owning a Packard was considered prestigious, and surviving examples are found in museums, car shows, and automobile collections. Packard vehicles featured innovations, including the modern steering wheel, air-conditioning in a passenger car, and one of the first production 12-cylinder engines, adapted from developing the Liberty L-12 engine used during World War I to power warplanes. During World War II, Packard produced 55,523 units of the two-stage/two-speed supercharger equipped Merlin V-12s engines under contract with Rolls-Royce. Packard also made the versions of the Liberty L-12 V-12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineering Magazine
''Engineering Magazine'' was an American illustrated monthly magazine devoted to industrial progress, first published in 1891. The periodical was published under this title until October 1916. Sequentially from Nov. 1916 to 1927 it was published as ''Industrial Management''. Engineering Magazine was a popular journal about engineering, technology, and industry. It described the system of manufacturing which has come to be known as distinctively American. Several leading authors of the efficiency movement published the first versions of their seminal works in the ''Engineering Magazine''. With Frederick W. Taylor named the father of scientific management, the ''Engineering Magazine'' has been called "the mother of the entire management movement."

Grand Palais
The Grand Palais des Champs-Élysées ( en, Great Palace of the Elysian Fields), commonly known as the Grand Palais (English: Great Palace), is a historic site, exhibition hall and museum complex located at the Champs-Élysées in the 8th arrondissement of Paris, France. Construction of the Grand Palais began in 1897 following the demolition of the Palais de l'Industrie (Palace of Industry) to prepare for the Universal Exposition of 1900. That exposition also produced the adjacent Petit Palais and Pont Alexandre III. The building was designed to be a large-scale venue for official artistic events. A pediment on the building refers to this function with an inscription that reads, "a monument dedicated by the Republic to the glory of French art." Designed according to Beaux-Arts tastes, the building features ornate stone facades, glass vaults and period innovations that included iron and light steel framing and reinforced concrete. It is listed as a historic monument (''monu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daniel McFarlan Moore
Daniel McFarlan Moore (February 27, 1869 – June 15, 1936) was a U.S. electrical engineer and inventor. He developed a novel light source, the "Moore lamp", and a business that produced them in the early 1900s. The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. Paid access. In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in early television systems. Early life He was born in Northumberland, Pennsylvania, on February 27, 1869. Moore was the son of the Reverend Alexander Davis and Maria Louisa Douglas Moore. He graduated from Lehigh University in 1889. Moore married Mary Alice Elliott, of New York City, on June 5, 1895. They had three children: Dorothy Mae Moore, (born 1900); Elliott McFarlan Moore (1902–1933); and Beatrice Jean Moore, (bor ...

Geissler Tube
A Geissler tube is an early gas discharge tube used to demonstrate the principles of electrical glow discharge, similar to modern neon lighting. The tube was invented by the German physicist and glassblower Heinrich Geissler in 1857. It consists of a sealed, partially evacuated glass cylinder of various shapes with a metal electrode at each end, containing rarefied gasses such as neon, argon, or air; mercury vapor or other conductive fluids; or ionizable minerals or metals, such as sodium. When a high voltage is applied between the electrodes, an electrical current flows through the tube. The current dissociates electrons from the gas molecules, creating ions, and when the electrons recombine with the ions, the gas emits light by fluorescence. The color of light emitted is characteristic of the material within the tube, and many different colors and lighting effects can be achieved. The first gas-discharge lamps, Geissler tubes were novelty items, made in many artistic shapes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
