Escape Set
An escape set (in German ''Tauchretter'' = "diving rescuer") is a breathing set that allows its wearer to survive for a time in an environment without (sufficiently) breathable air. Early escape sets were rebreathers and were typically used to escape from submarines with a depleted air supply that, for technical or military reasons, were unable to surface. One example is the Davis Submerged Escape Apparatus. Escape sets were also used ashore, e.g. in the mining industry, and for escape from tanks (Amphibious Tank Escape Apparatus). The small open-circuit scuba Helicopter Aircrew Breathing Device has the similar purpose of providing breathing gas to escape from a ditched helicopter. Naming Currently, language in German as in English, ''tauchen'' = "diving" only means in water. Until the middle of the 20th century the German word ''tauchen'' = "to dive" also meant "to stay in unbreathable atmosphere". Thus around 1900 a water-cooled fire protection hood with air supply for fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slaked Lime
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca( OH)2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide. Properties Calcium hydroxide is poorly soluble in water, with a retrograde solubility increasing from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. With a solubility product ''K''sp of 5.02 at 25 °C, its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction: : Ca(OH)2 → Ca2+ + 2 OH− At ambient temperature, calcium hydroxide (portlandite) ...

Siebe Gorman
Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe , a German-born British engineer chiefly known for his contributions to diving equipment. Siebe plc started in the 1970s as a continuation of Siebe Gorman when Siebe Gorman started to take over other firms, to mean the new conglomerate to distinguish it from Siebe Gorman's original breathing apparatus and diving gear core business. Siebe plc was once one of the United Kingdom's largest engineering businesses. It was a constituent of the FTSE 100 Index but in 1999 it merged with BTR plc to form Invensys. Invensys was taken over by the French multinational Schneider Electric for £3.4 billion in January 2014.

Robert Henry Davis
Sir Robert Henry Davis (1870 – 1965) was an English inventor and director of the Siebe Gorman company. His main invention was the Davis Submerged Escape Apparatus, an oxygen rebreather that Davis patented for the first time in 1910, inspired by the rebreathers that Henry Fleuss patented as of 1876. Davis breathing set was destined to allow British submarine crews to escape when their ship started to sink. While still directing Siebe Gorman Davis was the first British to buy a licence from the Cousteau- Gagnan Aqua-Lung (from the French company La Spirotechnique), starting commercialization of scuba sets in Britain as of 1948. Siebe Gorman aqualungs ended being known under the name of ''tadpole sets''. Davis Road in Chessington (where Siebe Gorman's factory was for a while) was named after him. Publications He wrote the books: * ''Diving Scientifically and Practically Considered. Being a Diving Manual and Handbook of Submarine Appliances'', first edition 1909, publis ...

Hypoxia (medical)
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either '' generalized'', affecting the whole body, or ''local'', affecting a region of the body. Although hypoxia is often a pathological condition, variations in arterial oxygen concentrations can be part of the normal physiology, for example, during strenuous physical exercise.. Hypoxia differs from hypoxemia and anoxemia, in that hypoxia refers to a state in which oxygen present in a tissue or the whole body is insufficient, whereas hypoxemia and anoxemia refer specifically to states that have low or no oxygen in the blood. Hypoxia in which there is complete absence of oxygen supply is referred to as anoxia. Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised gene ...

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Enemy Hands (film)
''In Enemy Hands'' is a 2004 American submarine film directed by Tony Giglio and starring William H. Macy, Til Schweiger, Thomas Kretschmann, Scott Caan and Lauren Holly. The film follows an American submarine crew getting captured by a German submarine crew and taken prisoner aboard their U-boat. Plot The movie begins with old film footage of World War II with a narrator explaining that Germany produced hundreds of U-boats to control the Atlantic. In 1942, groups of U-boats known as wolfpacks sank over a thousand Allied ships. The Germans began winning the war and if they continued to succeed in destroying the Allies, the Germans will conquer all of Europe. In 1943, Roosevelt and Churchill declared that stopping the U-boats was their main priority. With new technology and the United States committed to the war, the Allies begin destroying the U-boats and bringing an end to the wolfpacks. In June 1943, Lt. Cmdr. Randall Sullivan (Caan) talks about his upcoming mission with Adm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Das Boot
''Das Boot'' (, English: "The Boat") is a 1981 West German war film written and directed by Wolfgang Petersen, produced by Günter Rohrbach, and starring Jürgen Prochnow, Herbert Grönemeyer, and Klaus Wennemann. It has been exhibited both as a theatrical release and a TV miniseries (1985). There are also several different home video versions as well as a director's cut supervised by Petersen in 1997. An adaptation of Lothar-Günther Buchheim's 1973 German novel of the same name based on his experiences aboard , the film is set during World War II and follows ''U-96'' and its crew, as they set out on a hazardous patrol in the Battle of the Atlantic. It depicts both the excitement of battle and the tedium of the fruitless hunt, and shows the men serving aboard U-boats as ordinary individuals with a desire to do their best for their comrades and their country. Development began in 1979. Several American directors were considered three years earlier before the film was shelved. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulmonary Barotrauma
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or contact with, the body and the surrounding gas or liquid. The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the tissue. Tissue rupture may be complicated by the introduction of gas into the local tissue or circulation through the initial trauma site, which can cause blockage of circulation at distant sites or interfere with the normal function of an organ by its presence. Barotrauma generally manifests as sinus or middle ear effects, lung overpressure injuries and injuries resulting from external squeezes. Decompression sickness is indirectly caused by ambient pressure reduction, and tissue damage is caused directly and indirectly by gas bubbles. However, these bubbles form out of supersaturated solution fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
