Ohgushi's Peerless Respirator
Vintage scuba is scuba equipment dating from 1975 and earlier, and the practice of scuba diving, diving using such equipment. Twin hose regulators The most striking and well recognized example of vintage scuba gear is the Diving regulator#Twin-hose demand regulators, twin-hose or double hose regulator, a popular style of regulator in the early years of scuba diving, since Jacques-Yves Cousteau and Emile Gagnan pioneered the first such design, the C45 Scaphandre Autonome, which was marketed in the USA (along with a tank and harness) as the Aqua-Lung. The durability of the regulators from the 1950s through the early 1970s lent them to easily be refurbished and restored. Since 1997Vintage Scuba Supplyhas been supplying parts for original regulators. Vintage Double Hose supplies parts for a modern version of the double-hose scuba regulator. That regulator is composed of modern polymers and specialty metals. It allows for additional scuba equipment to be attached, such as a submers ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Diving Regulator
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] |
Diving Cylinder
A diving cylinder or diving gas cylinder is a gas cylinder used to store and transport high pressure gas used in diving operations. This may be breathing gas used with a scuba set, in which case the cylinder may also be referred to as a scuba cylinder, scuba tank or diving tank. When used for an emergency gas supply for surface supplied diving or scuba, it may be referred to as a bailout cylinder or bailout bottle. It may also be used for surface-supplied diving or as decompression gas . A diving cylinder may also be used to supply inflation gas for a dry suit or buoyancy compensator. Cylinders provide gas to the diver through the demand valve of a diving regulator or the breathing loop of a diving re-breather. Diving cylinders are usually manufactured from aluminum or steel alloys, and when used on a scuba set are normally fitted with one of two common types of cylinder valve for filling and connection to the regulator. Other accessories such as manifolds, cylinder ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ted Eldred
Edward Francis Eldred (16 December 1920 to August 2005) was a pioneer of scuba diving in Australia. He invented Porpoise scuba gear. Early years Eldred was born in Melbourne in 1920. As a young man he lived by the sea near Sorrento on the Mornington Peninsula south of Melbourne. He started snorkelling as soon as mask, fins and snorkel were available, and wished that he could make or obtain some sort of free-swimming breathing set, until World War II intervened. After World War II in the late 1940s he designed a sport diving oxygen rebreather. Eldred said he had never dived with the Cousteau-Gagnan model of the Aqua Lung, but knew of its existence and its principle. The Aqua Lung was protected by patent and difficult to obtain in Australia. Siebe Gorman had the license to manufacture for Commonwealth countries and could not meet demands. When Eldred decided that rebreathers were not suitable for general sport use, he shifted his focus to developing the world's first single-hose ...

Scuba Set
A scuba set, originally just scuba, is any breathing apparatus that is entirely carried by an underwater diving, underwater diver and provides the diver with breathing gas at the ambient pressure. ''Scuba'' is an anacronym for self-contained underwater breathing apparatus. Although strictly speaking the scuba set is only the diving equipment that is required for providing breathing gas to the diver, general usage includes the harness or rigging by which it is carried and those accessories which are integral parts of the harness and breathing apparatus assembly, such as a jacket or wing style Buoyancy compensator (diving), buoyancy compensator and instruments mounted in a combined housing with the pressure gauge. In the looser sense, scuba set has been used to refer to all the diving equipment used by the scuba diver, though this would more commonly and accurately be termed scuba equipment or scuba gear. Scuba is overwhelmingly the most common underwater breathing system used by r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-contained Breathing Apparatus
A self-contained breathing apparatus (SCBA) is a respirator worn to provide an autonomous supply of breathable gas in an atmosphere that is immediately dangerous to life or health from a gas cylinder. They are typically used in firefighting and industry. The term ''self-contained'' means that the SCBA is not dependent on a remote supply of breathing gas (e.g., through a long hose). They are sometimes called industrial breathing sets. Some types are also referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA). Unofficial names include ''air pack'', ''air tank'', ''oxygen cylinder'' or simply ''pack'', terms used mostly in firefighting. If designed for use under water, it is also known as a scuba set (self-contained underwater breathing apparatus). An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., , about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may ...

Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantial unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, while also eliminating the bubbles otherwise produced by an open circuit system. The latter advantage over other systems is useful for covert military operations by frogmen, as well as for undisturbed observation of underwater wildlife. A rebreather is generally understood to be a portable apparatus carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supp ...
