Diving Suits
A diving suit is a garment or device designed to protect a diver from the underwater environment. A diving suit may also incorporate a breathing gas supply (such as for a standard diving dress or atmospheric diving suit). but in most cases the term applies only to the environmental protective covering worn by the diver. The breathing gas supply is usually referred to separately. There is no generic term for the combination of suit and breathing apparatus alone. It is generally referred to as diving equipment or dive gear along with any other equipment necessary for the dive. Diving suits can be divided into two classes: "soft" or ambient pressure diving suits – examples are wetsuits, dry suits, semi-dry suits and dive skins – and "hard" or atmospheric pressure diving suits, armored suits that keep the diver at atmospheric pressure at any depth within the operating range of the suit. Function The diving suit is worn as protection from the diving environment. This ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RMS Lusitania
RMS ''Lusitania'' (named after the Roman province in Western Europe corresponding to modern Portugal) was a British ocean liner that was launched by the Cunard Line in 1906 and that held the Blue Riband appellation for the fastest Atlantic crossing in 1908. It was briefly the world's largest passenger ship until the completion of the three months later. She was sunk on her 202nd trans-Atlantic crossing, on 7 May 1915, by a German U-boat U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role ... off the southern coast of Ireland, killing 1,198 passengers and crew. The sinking occurred about two years before the United States declaration of war on Germany (1917), United States declaration of war on Germany.

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

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.

Sladen Suit
The Sladen Suit was a heavy type of British divers' drysuit made by Siebe Gorman. It is entered by a wide rubber tube at the umbilicus: this tube is folded and tied off before the diver dives. It was used by British manned torpedo Human torpedoes or manned torpedoes are a type of diver propulsion vehicle on which the diver rides, generally in a seated position behind a fairing. They were used as secret naval weapons in World War II. The basic concept is still in use. ... riders and for general underwater work. It was sometimes nicknamed "Clammy Death". The first model had two small glazed viewports. It was redesigned with the single oval flip-up viewport so the wearer could get binoculars to his eyes. "Universal" rebreather There was an oxygen rebreather called the "Universal" that was designed to be used with it. The Universal was a long-dive derivative of the Davis Submerged Escape Apparatus.

Charles Macintosh
Charles Macintosh FRS (29 December 1766 – 25 July 1843) was a Scottish chemist and the inventor of the modern waterproof raincoat. The Mackintosh raincoat (the variant spelling is now standard) is named after him. Biography Macintosh was born in Glasgow, Scotland, the son of George Macintosh and Mary Moore, and was first employed as a clerk. Charles devoted his spare time to science, particularly chemistry, and before he was 20 resigned his clerkship to study under Joseph Black at the University of Edinburgh, and to take up the manufacture of chemicals. In this he was highly successful and invented various new processes. His experiments with naphtha led to his invention of waterproof rubberized fabric; the essence of his patent was the cementing of two thicknesses of cloth together with natural rubber. The rubber is made soluble by the action of the naphtha. The naphtha was prepared by distillation of coal tar, with the Bonnington Chemical Works being a major supplier. Maci ...

Canvas
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, shelters, as a support for oil painting and for other items for which sturdiness is required, as well as in such fashion objects as handbags, electronic device cases, and shoes. It is popularly used by artists as a painting surface, typically stretched across a wooden frame. Modern canvas is usually made of cotton or linen, or sometimes polyvinyl chloride (PVC), although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven. The term ''duck'' comes from the Dutch word for cloth, ''doek''. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a graded number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diving Helmet
A diving helmet is a rigid head enclosure with a breathing gas supply used in underwater diving. They are worn mainly by professional divers engaged in surface-supplied diving, though some models can be used with scuba equipment. The upper part of the helmet, known colloquially as the ''hat'' or ''bonnet'', may be sealed directly to the diver using a ''neck dam'', connected to a diving suit by a lower part, known as a ''breastplate'', or ''corselet'', depending on regional language preferences. or simply rest on the diver's shoulders, with an open bottom, for shallow water use. The helmet isolates the diver's head from the water, allows the diver to see clearly underwater, provides the diver with breathing gas, protects the diver's head when doing heavy or dangerous work, and usually provides voice communications with the surface (and possibly other divers). If a helmeted diver becomes unconscious but is still breathing, most helmets will remain in place and continue to deliver b ...

John Deane (inventor)
John Deane (1800–1884; known as The ''Infernal Diver''), with his brother Charles, invented the diving helmet and performed diving operations at the wreck of the ''Mary Rose''. They received their education at The Royal Hospital School, Greenwich and were both in attendance in 1812. When he was 14, John joined the East India Company and sailed for seven years. In the 1820s, John was present in England when horses were trapped by fire in a stable. To get through the smoke and fire fumes he put on a medieval knight-in-armour helmet air-pumped by hose from a fire brigade water pump and rescued all the horses. In 1823, he patented a "Smoke Helmet" to be used by firemen in smoke-filled areas; the full title is given as ''"Apparatus or Machines to be worn by Persons entering Rooms or other places filled with Smoke of other Vapour, for the purpose of extinguishing Fire, or extricating Persons or Property therein"''. The apparatus comprised a copper helmet with an attached flexible c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustus Siebe
Christian Augustus Siebe (known by his middle name; 1788 – 15 April 1872) was a German-born British engineer chiefly known for his contributions to diving equipment. Contribution to diving In the 1830s the Deane brothers asked Siebe to make a variation of their smoke helmet design for underwater use. Later they turned to him to produce more helmets for diving operations. Expanding on improvements already made by another engineer, George Edwards, Siebe produced his own design; a helmet fitted to a full length watertight canvas diving suit. The real success of the equipment was a valve in the helmet. Colonel Charles Pasley, leader of the Royal Navy team that used Siebe's suit on the wreck of suggested the helmet should be detachable from the corset, giving rise to the typical standard diving dress which revolutionised underwater civil engineering, underwater salvage, commercial diving and naval diving. The company that carried his name Siebe Gorman Ltd was founded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
