Standard Diving Dress
Standard diving dress, also known as hard-hat or copper hat equipment, deep sea diving suit or heavy gear, is a type of diving suit that was formerly used for all relatively deep underwater work that required more than breath-hold duration, which included marine salvage, civil engineering, pearl shell diving and other commercial diving work, and similar naval diving applications. Standard diving dress has largely been superseded by lighter and more comfortable equipment. Standard diving dress consists of a diving helmet made from copper and brass or bronze, clamped over a watertight gasket to a waterproofed canvas suit, an air hose from a surface-supplied manually operated pump or low pressure breathing air compressor, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes. Later models were equipped with a diver's telephone for voice communications with the surface. The term ''deep sea diving'' was used to distinguish diving with th ...

Ožbalt
Ožbalt () is a village on the left bank of the Drava River in the Municipality of Podvelka in Slovenia. Name The name of the settlement was changed from ''Sveti Ožbalt'' (literally, 'Saint Oswald') to ''Ožbalt'' (literally, 'Oswald') in 1952. The name was changed on the basis of the 1948 Law on Names of Settlements and Designations of Squares, Streets, and Buildings as part of efforts by Slovenia's postwar communist government to remove religious elements from toponyms.Urbanc, Mimi, & Matej Gabrovec. 2005.

Buoyancy
Buoyancy (), or upthrust, is the force exerted by a fluid opposing the weight of a partially or fully immersed object (which may be also be a parcel of fluid). In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the Displacement (fluid), displaced fluid. For this reason, an object with average density greater than the surrounding fluid tends to sink because its weight is greater than the weight of the fluid it displaces. If the objec ...

Cave Diving Equipment 1935
Caves or caverns are natural voids under the Earth's Planetary surface, surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called Caving, ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sedime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Augustus Siebe
Christian Augustus Siebe (known by his middle name; 1788 – 15 April 1872) was a British engineer chiefly known for his contributions to diving equipment. Contribution to diving In the 1830s the John Deane (inventor), 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 diving helmet, 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 corselet (diving helmet), corselet, giving rise to the typical standard diving dress which revolutionised underwater civil engineering, underwater Marine salvage, salvage, commercial diving and naval diving ...

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] |
Charles Anthony Deane
Charles Anthony Deane (1796–1848) was a pioneering diving engineer, inventor of the diving helmet. Life Born in Deptford, Charles and his brother John studied at the Greenwich Hospital School for Boys (the former buildings of which are now the National Maritime Museum) to become merchant seamen, going to sea at the age of 14 for a period of 7 years before returning to Deptford. Charles Deane then took up employment as a caulker at Barnard's Shipyard. During this time he realised the problem of fighting fires within the holds of ships. In the 1820s John Deane 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-armor helmet air-pumped by hose from a fire brigade water pump, and rescued all the horses.

Giovanni Alfonso Borelli
Giovanni Alfonso Borelli (; 28 January 1608 – 31 December 1679) was a Renaissance Italy, Italian physiologist, physicist, and mathematician who is often described as the father of biomechanics. He contributed to the modern principle of scientific investigation by continuing Galileo Galilei, Galileo's practice of testing hypotheses against observation. Trained in mathematics, Borelli also made extensive studies of Jupiter's moons, the mechanics of animal locomotion and, in microscopy, of the constituents of blood. He also used microscopy to investigate the stomatal movement of plants, and undertook studies in medicine and geology. During his career, he enjoyed the patronage of Queen Christina of Sweden. He was the first scientist to explain that animal and human bodily movements are caused by muscular contractions. Biography Giovanni Borelli was born on 28 January 1608 in the district of Castel Nuovo, in Naples. He was the first-born son of Spanish infantryman Miguel Alfonso and ...

Konrad Kyeser
Konrad Kyeser (26 August 1366 – after 1405) was a German military engineer and the author of '' Bellifortis'' (), a book on military technology that was popular throughout the 15th century. Originally conceived for King Wenceslaus, Kyeser dedicated the finished work to Rupert of Germany. A native of Eichstätt, Kyeser was trained as a physician and lived at the court in Padua before he joined the crusade against the Turks which ended in disaster at the Battle of Nicopolis in 1396. Kyeser lived in exile in a mountain village in Bohemia during the reign of Sigismund in 1402 to 1403. Bellifortis During his time in exile, Kyeser began to write his book on the military arts. The book is the most prominent illustrated treatise on military engineering of the Late Middle Ages. There are at least twelve surviving 15th-century manuscripts which copy, excerpt, or amplify the work. One of these is the ''Thott'' Fechtbuch of Hans Talhoffer (1459). The book is divided int ...

Mid-water
The diving environment is the natural or artificial surroundings in which a dive is done. It is usually underwater, but professional diving is sometimes done in other liquids. Underwater diving is the human practice of voluntarily descending below the surface of the water to interact with the surroundings, for various recreational or occupational reasons, but the concept of diving also legally extends to immersion in other liquids, and exposure to other pressurised environments. Some of the more common diving environments are listed and defined here. The diving environment is limited by accessibility and risk, but includes water and occasionally other liquids. Most underwater diving is done in the shallower coastal parts of the oceans, and inland bodies of fresh water, including lakes, dams, quarries, rivers, springs, flooded caves, reservoirs, tanks, swimming pools, and canals, but may also be done in large bore ducting and sewers, power station cooling systems, cargo and bal ...
