Bathysphere
The ''Bathysphere'' () was a unique spherical deep sea, deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934. The ''Bathysphere'' was designed in 1928 and 1929 by the American engineer Otis Barton, to be used by the naturalist William Beebe for studying undersea wildlife. Beebe and Barton conducted dives in the ''Bathysphere'' together, marking the first time that a marine biology, marine biologist observed deep-sea animals in their native environment. Their dives set several consecutive world records for the deepest dive ever performed by a human. The record set by the deepest of these, to a depth of on August 15, 1934, lasted until it was broken by Barton in 1949 in a vessel called Benthoscope. Origin and design In 1928, the American naturalist William Beebe was given permission by the British government to establish a research station on Nonsuch Island, Bermuda. U ...

Benthoscope
The Benthoscope was a deep sea submersible designed by Otis Barton after the Second World War. He hired the Watson-Stillman Company, who had earlier constructed his and William Beebe's bathysphere, to produce the new design of deep diving vessel, which was named from the Greek ''benthos'', meaning "bottom". The Benthoscope was essentially similar to the bathysphere, but was built to withstand higher pressures, with a crush depth of . Its internal diameter was , and its wall thickness was . It weighed , an increase in weight of over the bathysphere. Two windows of fused quartz were installed, one facing straight ahead and the other diagonally down. Other arrangements followed the bathysphere, with oxygen supplied from cylinders, and calcium chloride and soda lime used to absorb moisture and CO2 respectively. In August 1949, Barton established a new world depth record with a solo descent to , which remains the deepest dive by a submersible suspended by a cable. The Benthoscope is ...

Otis Barton
Frederick Otis Barton Jr. (June 5, 1899 – April 15, 1992) was an American deep-sea diver, inventor and actor. Early life and career Born in New York, the independently wealthy Barton designed the first bathysphere and made a dive with William Beebe off Bermuda in June 1930. They set the first record for deep-sea diving by descending . In 1934, they set another record at . Barton acted in the 1938 Hollywood movie, '' Titans of the Deep''. Later career In 1949, Barton set a new world record with a 4,500 foot (1,372 m) dive in the Pacific Ocean, using his benthoscope (from the Greek ''benthos'', meaning 'sea bottom', and ''scopein'', 'to view'), which was designed by Barton and Maurice Nelles. Barton wrote the book ''The World Beneath the Sea'', published in 1953. Like Beebe, Barton was also interested in exploring tropical rain forests, and spent considerable time in places like Gabon. In 1978, Barton successfully tested a "jungle spaceship" (actually an airship An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nonsuch Island, Bermuda
Nonsuch Island (originally Nonesuch Island) is part of the chain of islands which make up Bermuda. It is in St George's Parish, in the northeast of Bermuda. It is 5.7 ha (14 acres) in area and is at the east entrance to Castle Harbour, close to the south-easternmost point of Cooper's Island (cojoined with the much larger St David's Island by the construction of Kindley Field by the United States Army during the Second World War). Among the island's charted features is a bay called Nonsuch Bay. History In 1865 it served as a yellow fever quarantine hospital. On the eastern part of the island there still remains a small cemetery. In 1930 it served as a base for William Beebe and Otis Barton's landmark bathysphere dive. Environment The island is a wildlife sanctuary. It is wooded and with a small freshwater marsh; access to the public is strictly limited. The restoration of the once barren island into a 'Living Museum of pre-colonial Bermuda' is the lifetime work of now r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fused Quartz
Fused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO2) in amorphous (non-crystalline) form. This differs from all other commercial glasses, such as soda-lime glass, lead glass, or borosilicate glass, in which other ingredients are added which change the glasses' optical and physical properties, such as lowering the melt temperature, the spectral transmission range, or the mechanical strength. Fused quartz, therefore, has high working and melting temperatures, making it difficult to form and less desirable for most common applications, but is much stronger, more chemically resistant, and exhibits lower thermal expansion, making it more suitable for many specialized uses such as lighting and scientific applications. The terms ''fused quartz'' and ''fused silica'' are used interchangeably but can refer to different manufacturing techniques, resulting in different trace impurities. However fused quartz, being in the glassy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathytroctes
''Bathytroctes'' is a genus of deepwater marine ray-finned fishes belonging to the family Alepocephalidae Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from ..., the smooth-heads. These fishes are found in the deeper waters of the Oceans around the world.. Species There are currently 11 recognized species in this genus: * '' Bathytroctes breviceps'' Sazonov, 1999 * '' Bathytroctes elegans'' Sazonov & A. N. Ivanov, 1979 * '' Bathytroctes inspector'' Garman, 1899 * '' Bathytroctes macrognathus'' Sazonov, 1999 * '' Bathytroctes macrolepis'' Günther, 1887 (Koefoed's smooth-head) * '' Bathytroctes michaelsarsi'' Koefoed, 1927 (Michael Sars' smooth-head) * '' Bathytroctes microlepis'' Günther, 1878 (Smallscale smooth-head) * '' Bathytroctes oligolepis'' ( G.

Stuffing Box
A stuffing box or gland package is an assembly which is used to house a gland seal. It is used to prevent leakage of fluid, such as water or steam, between sliding or turning parts of machine elements. Components A stuffing box of a sailing boat will have a stern tube that is slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal. The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft. , WindCheck Magazine, Retrieved April 27, 2016. Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific ...
