Submarine Communications Cable
A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fibre technology to carry digital data, which includes telephone, Internet and private data traffic. Modern cables are typically about in diameter and weigh around for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Terr ...

The Cables
The Cables are a Jamaican rocksteady/reggae vocal trio led by Keble Drummond, who recorded for Studio One in the late 1960s. History The group was led by Keble Drummond (sometimes spelled Keeble), whose first name led to the name of the group.Peter I (2004)Interview With The Cables, ''Reggae Vibes'' Drummond explained "Now, I look at something with a cable and wires, and I say, well, 'Cables' would be a good name because you could send a message across the world, and that's how I came up with the name". He was backed by harmony singers Elbert Stewart (baritone) and Vince Stoddart (tenor).Larkin, Colin (1998) "The Virgin Encyclopedia of Reggae", Virgin Books, Drummond was taught the basics of guitar by Peter Austin of The Clarendonians and write his first songs after attending a songwriting course. Drummond had previously been a member of The Sylastians, along with Barry Llewellyn and Earl Morgan of The Heptones, and Clive Campbell of The Aces, and the Cables were first formed i ...

Coaxial Cable
Coaxial cable, or coax (pronounced ) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ( insulating material); many coaxial cables also have a protective outer sheath or jacket. The term ''coaxial'' refers to the inner conductor and the outer shield sharing a geometric axis. Coaxial cable is a type of transmission line, used to carry high-frequency electrical signals with low losses. It is used in such applications as telephone trunk lines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas. It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line. Coaxial cable was used in the first (1858) and followin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Cable
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. One or more electrical cables and their corresponding connectors may be formed into a ''cable assembly'', which is not necessarily suitable for connecting two devices but can be a partial product (e.g. to be soldered onto a printed circuit board with a connector mounted to the housing). Cable assemblies can also take the form of a cable tree or cable harness, used to connect many terminals together. Etymology The original meaning of ''cable'' in the electrical wiring sense was for submarine telegraph cables that were armoured with iron or steel wires. Early attempts to lay submarine cables without armouring failed because they were too easily damaged. The armouring in these early days (mid-19th century) was implemented in separate factories to the factories making the cable cores. These companies were specialists in manufacturing wire rope of ...

Power Cable
A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Power cables that are bundled inside thermoplastic sheathing and that are intended to be run inside a building are known as NM-B (nonmetallic sheathed building cable). Flexible power cables are used for portable devices, mobile tools, and machinery. History The first power distribution system developed by Thomas Edison in 1882 in New York City used copper rods, wrapped in jute and placed in rigid pipes filled with a bituminous compound. Although vulcanized rubber had been patented by Charles Goodyear in 1844, it was not applied to cable insulation until the 1880s, when it was used for lighting circuits. Rubber-insulated cable was used for 11,000-volt circuits in 1897 install ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowden Cable
A Bowden cable ( ) is a type of flexible cable used to transmit mechanical force or energy by the movement of an inner cable relative to a hollow outer cable housing. The housing is generally of composite construction, consisting of an inner lining, a longitudinally incompressible layer such as a helical winding or a sheaf of steel wire, and a protective outer covering. The linear movement of the inner cable is most often used to transmit a pulling force, although push/pull cables have gained popularity in recent years e.g. as gear shift cables. Many light aircraft use a push/pull Bowden cable for the throttle control, and here it is normal for the inner element to be a solid wire, rather than a multi-strand cable. Usually, provision is made for adjusting the cable tension using an inline hollow bolt (often called a "barrel adjuster"), which lengthens or shortens the cable housing relative to a fixed anchor point. Lengthening the housing (turning the barrel adjuster out) ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber-optic Cable
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for different applications, for example, long distance telecommunication, or providing a high-speed data connection between different parts of a building. Design Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough ...

Cablegram
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling. This ...

Cable Knitting
Cable knitting is a style of knitting in which textures of crossing layers are achieved by permuting stitches. For example, given four stitches appearing on the needle in the order ', one might cross the first two (in front of or behind) the next two, so that in subsequent rows those stitches appear in the new order '. Methods The stitches crossing behind are transferred to a small ''cable needle'' for storage while the stitches passing in front (or behind) are knitted. The former stitches are then transferred back to the original needle or knitted from the cable needle itself. Rather than use a cable needle, some knitters prefer to use a large safety pin or, for a single stitch, simply hold it in their fingers while knitting the other stitch(es). Cabling is typically done only when working on the right side of the fabric, i.e., every other row. This creates a ''spacer row'', which helps the fabric to relax. Cable knitting usually produces a fabric that is less flexible and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wire Rope
Steel wire rope (right hand lang lay) Wire rope is several strands of metal wire twisted into a helix forming a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run. Wire ropes were developed starting with min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable (comic Book)
''Cable'' is the name of multiple comic book titles featuring the character Cable and published by Marvel Comics, beginning with the original ''Cable'' comic book series which debuted in 1993. Publication history In 1992, the character was featured in his first solo series, a two issue miniseries, titled ''Cable: Blood and Metal'', written by Fabian Nicieza, pencilled by John Romita, Jr., and inked by Dan Green, published in October and November of that year. Volume 1 Shortly after ''Blood and Metal'', Cable was given his own ongoing series titled ''Cable''. The book initially had trouble finding a stable creative team. A writer/penciller team would complete no more than three issues in a row until Jeph Loeb and Ian Churchill began work on issue #20 and finish on #35 (though with a gap between issues #20 and #21 due to the Age of Apocalypse event). Loeb and Churchill provided the first instance of stability, working together on 15 of the 20 issues from #20–39. During their run ...

USS Cable (ARS-19)
USS ''Cable'' (ARS-19) was a built for the U.S. Navy during World War II. She served in the Pacific Ocean theater of the war. Because of the bravery of her crew in dangerous combat areas, she returned home after the war's end with three battle stars and the Navy Unit Commendation. ''Cable'' was launched 1 April 1943 by Basalt Rock Company in Napa, California; sponsored by Mrs. B. Elliott; and commissioned 6 March 1944. World War II Pacific Theatre operations ''Cable'' began her salvage and rescue work while still in shakedown training, when she took in tow for San Diego, California, the water barge ''AW-86'', which had suffered a breakdown off Cape San Lucas, Mexico. ''Cable'' cleared San Pedro, California, 30 April 1944, towing small craft to Kwajalein on her way to Milne Bay, New Guinea. Here she offered salvage and rescue services until sailing 10 August for Manus and Cairns, Australia, where she loaded firefighting and salvage teams. Continuing the lengthy process of i ...
