Denayrouze
August Denayrouze (1 October 1837 – 1 January 1883) was a French engineer and inventor. He was the 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 1 October 1837 in Montpeyroux, Aveyron, France. 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benoît Rouquayrol
Benoît Rouquayrol (1826–1875) was a French inventor. Along with Auguste Denayrouze, Rouquayrol invented a diving suit and breathing apparatus. Biography Benoît Rouquayrol was born on 13 June 1826 in Espalion, in the Aveyron department of Southern France. He became an engineer at the 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 lieutenant Auguste Denayrouze (also of Aveyron), Rouquayrol created a diving suit. which won the gold medal at the 1867 World's Fair, and drew the attention of the author Jules Verne.

Demand Valve
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving. The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications. The gas may be air or one of a variety of specially blended breathing gases. The gas may be supplied from a scuba cylinder carried by the diver, in which case it is called a scuba regulator, or via a hose from a compressor or high-pressure storage cylinders at the surface in surface-supplied diving. A gas pressure regulator has one or more valves in series which reduce pressure from the source, and use the downstream pressure as feedback to control the delivered pressure, or the upstream pressure as feedback to prevent excessive flow rates, lowering the pressure at each stage. The terms "regulator" and "demand valve" (DV) are of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Nautilus
''Nautilus'' is the fictional submarine belonging to Captain Nemo featured in Jules Verne's novels ''Twenty Thousand Leagues Under the Seas'' (1870) and '' The Mysterious Island'' (1875). Description ''Nautilus'' is described by Verne as "a masterpiece containing masterpieces". It is designed and commanded by Captain Nemo. Electricity provided by sodium/ mercury electric batteries (with the sodium provided by extraction from seawater) is the craft's primary power source for propulsion and other services. The energy needed to extract the sodium is provided by coal mined from the sea floor. ''Nautilus'' is double-hulled, and is further separated into water-tight compartments. Its top speed is . In Captain Nemo's own words: ''Nautilus'' uses floodable tanks in order to adjust buoyancy and so control its depth. The pumps that evacuate these tanks of water are so powerful that they produce large jets of water when the vessel emerges rapidly from the surface of the water. ...
