Benoît Rouquayrol
Benoît Rouquayrol (1826–1875) was a List of French inventions and discoveries, French inventor. Along with Auguste Denayrouze, Rouquayrol invented a diving suit and breathing apparatus. Biography Benoît Rouquayrol was born on June 13, 1826, at Espalion, in the Aveyron department of Southern France. He became an engineer at the École Nationale Supérieure des Mines de Saint-Étienne, Saint-Étienne School of Mines. He became employed at a company involved in bituminous coal mining and foundries in Aveyron, and became the director of accounting by 1865. In 1860, Rouquayrol became concerned with mine safety problems related to firedamp (flammable natural gases in coal mines). He created a rescue apparatus consisting of a pressurized gas chamber coupled to a pressure regulator that he called the "Regulator for Equalization of Compressed Gas". In 1864, with the help of the French Navy Ship-of-the-line lieutenant, lieutenant Auguste Denayrouze (also of Aveyron), Rouquayrol create ...

Rodez
Rodez ( or ; oc, Rodés, ) is a small city and commune in the South of France, about 150 km northeast of Toulouse. It is the prefecture of the department of Aveyron, region of Occitania (formerly Midi-Pyrénées). Rodez is the seat of the communauté d'agglomération Rodez Agglomération, of the First Constituency of Aveyron as well as of the general Council of Aveyron. Former capital of the Rouergue, the city is seat of the Diocese of Rodez and Vabres. Its inhabitants are called ''Ruthénois'', from the name of the Ruteni, a Gallic tribe which once occupied the territory, the former demonym of "Rodanois" (from Occitan ''rodanés'') having given way to this scholarly form.

20,000 Leagues Under The Sea
''Twenty Thousand Leagues Under the Seas'' (french: Vingt mille lieues sous les mers) is a classic science fiction adventure novel by French writer Jules Verne. The novel was originally serialized from March 1869 through June 1870 in Pierre-Jules Hetzel's fortnightly periodical, the . A deluxe octavo edition, published by Hetzel in November 1871, included 111 illustrations by Alphonse de Neuville and Édouard Riou. The book was widely acclaimed on its release and remains so; it is regarded as one of the premier adventure novels and one of Verne's greatest works, along with ''Around the World in Eighty Days'' and ''Journey to the Center of the Earth''. Its depiction of Captain Nemo's underwater ship, the ''Nautilus'', is regarded as ahead of its time, since it accurately describes many features of today's submarines, which in the 1860s were comparatively primitive vessels. A model of the French submarine ''Plongeur'' (launched in 1863) figured at the 1867 Exposition Universel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Verne

World's Fair
A world's fair, also known as a universal exhibition or an expo, is a large international exhibition designed to showcase the achievements of nations. These exhibitions vary in character and are held in different parts of the world at a specific site for a period of time, typically between three and six months. The term "world's fair" is commonly used in the United States, while the French term, ("universal exhibition") is used in most of Europe and Asia; other terms include World Expo or Specialised Expo, with the word expo used for various types of exhibitions since at least 1958. Since the adoption of the 1928 Convention Relating to International Exhibitions, the Paris-based Bureau International des Expositions has served as an international sanctioning body for international exhibitions; four types of international exhibition are organised under its auspices: World Expos, Specialised Expos, Horticultural Expos (regulated by the International Association of Horticultural ...

Auguste Denayrouze
August Denayrouze (1837–1883) was an inventor of a demand valve for control of breathing air supply, and one of the inventors of a diving suit, along with Benoît Rouquayrol. Biography Denayrouze was born on October 1, 1837, at Montpeyroux, Aveyron, France, on the Aubrac plateau. In 1852, at the age of fifteen, he was admitted to the Naval School. He was promoted to lieutenant de vaisseau in 1862, and embarked on an expedition to Cochinchina (present-day Vietnam). He contracted a serious illness which rendered him unfit for service at sea. While recovering in the commune of Espalion, Denayrouze met Benoît Rouquayrol, with whom he collaborated in several inventions. Since 1860, Rouquayrol took out three patents for equipment intended for mining emergencies, to supply miners with air in case of firedamp or flooding of the mine. Denayrouze investigated the possibility of adapting the pressure regulator and developing it for underwater use. The two men thus designed and ...

Pressure Regulator
A pressure regulator is a valve that controls the pressure of a fluid or gas to a desired value, using negative feedback from the controlled pressure. Regulators are used for gases and liquids, and can be an integral device with a pressure setting, a restrictor and a sensor all in the one body, or consist of a separate pressure sensor, controller and flow valve. Two types are found: The pressure reduction regulator and the back-pressure regulator. *A pressure reducing regulator is a control valve that reduces the input pressure of a fluid or gas to a desired value at its output. It is a normally-open valve and is installed upstream of pressure sensitive equipment. *A back-pressure regulator, back-pressure valve, pressure sustaining valve or pressure sustaining regulator is a control valve that maintains the set pressure at its inlet side by opening to allow flow when the inlet pressure exceeds the set value. It differs from an over-pressure relief valve in that the over-pressu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
