Chain Markers
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be ...

Carabiner
A carabiner or karabiner (), often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German language, German , short for , meaning "carbine hook," as the device was used by carabiniers to attach their carbines to their belts. Use Carabiners are widely used in rope-intensive activities such as climbing, fall arrest systems, arboriculture, caving, sailing, hot air ballooning, hot-air ballooning, rope rescue, construction, industrial rope access, industrial rope work, window cleaning, whitewater rescue, and acrobatics. They are predominantly made from both steel and aluminium. Those used in sports tend to be of a lighter weight than those used in commercial applications and rope rescue. Often referred to as carabiner-style or as mini-carabiners, carabiner keyrings and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chainsaw
A chainsaw (or chain saw) is a portable handheld power saw, power saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are typically gasoline or electric and are used in activities such as tree felling, limbing, Log bucking, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of Wood fuel#Firewood, firewood, for use in Chainsaw carving, chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century. A chainsaw comprises an engine, a drive mechanism, a guide bar, a cutting chain, a tensioning mechanism, and safety features. Various safety practices and working techniques are used with chainsaws. History In surgery A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (–1785) by two Scot ...

Chain Pumps
The chain pump is type of a water pump in which several circular discs are positioned on an endless chain. One part of the chain dips into the water, and the chain runs through a tube, slightly bigger than the diameter of the discs. As the chain is drawn up the tube, water becomes trapped between the discs and is lifted to and discharged at the top. Chain pumps were used for centuries in the ancient Middle East, Europe, and China. In the Near East and Europe The earliest evidence for this device is in a Babylonian text from about 700 B.C. They were commonly powered by humans or animals. The device then appeared in ancient Egypt from about 200 B.C., featuring a pair of gear-wheels. A version of the chain pump was used in ancient Greece and Rome, sometimes with pots, or scoops fixed to the chain, which, as they passed over the top pulley, tipped the water out; a 2nd-century example is preserved in London. Philo of Byzantium wrote of such a device in the 2nd century B.C.; the historia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chain Gun
A chain gun is a type of autocannon or machine gun that uses an external source of power to cycle the weapon's action via a continuous loop of chain, similar to that used on a motorcycle or bicycle, instead of diverting excess energy from the cartridges' propellant as in a typical automatic firearm. History In 1972, Hughes Helicopters began a company-funded research effort to design a single machine gun to fire the U.S. Army's M50 round. In April 1973, the program fired test rounds in more powerful WECOM linked ammunition, from a prototype A model. In January 1975, a model "C" was added, a linkless version for the proposed Advanced Attack Helicopter YAH-64. The helicopter was later adopted as the Hughes Model 77/AH-64A Apache, with the model C receiving the designation M230 chain gun as its standard armament. In 1976, Hughes Helicopters patented the chain gun, and it has since been further developed into several other systems of different calibers.Richardson & Peaco ...

Bicycle Chain
A bicycle chain is a roller chain that transfers power (physics), power from the Bicycle pedal, pedals to the Drive wheel, drive-Bicycle wheel, wheel of a bicycle, thus propelling it. Most bicycle chains are made from carbon steel, plain carbon or alloy steel, but some are nickel electroplating, nickel-plated to prevent rust, or simply for aesthetics. History Obsolete chain designs previously used on bicycles included the bar-link chain, block chain, the skip-link chain, and the Simpson lever chain. The first chains were of a simple, bushing-less design. These had inherent reliability problems and a bit more friction (and mechanical efficiency losses) than modern chains. With these limitations in mind, the Nevoigt brothers, of the German Diamant (German bicycle company), Diamant Bicycle Company, designed the roller chain in 1898, which uses bushings. More recently, the "bushingless roller chain" design has superseded the bushed chain. This design incorporates the bearing surfac ...

Livery Collar
A livery collar or chain of office is a collar (jewelry), collar or heavy Link chain, chain, usually of gold, worn as insignia of office or a mark of fealty or other association in Europe from the Middle Ages onwards. One of the oldest and best-known livery collars is the #Collar of Esses, Collar of Esses, which has been in continuous use in England since the 14th century. History Origins Various forms of livery were used in the Middle Ages to denote attachment to a great person by friends, servants, and political supporters. The collar, usually of precious metal, was the grandest form of these, usually given by the person the livery denoted to his closest or most important associates, but should not, in the early period, be seen as separate from the wider phenomenon of livery badges, clothes and other forms. From the collar hung a heraldic badge, badge or device indicating the person the livery related to; the most important part of the ensemble for contemporaries. Equally gold ...

Belly Chain
A belly chain or waist chain is the popular English term for the Indian jewelry called ''kamarbandh''. The belly chain is a type of body jewelry worn around the waist. Some belly chains attach to a navel piercing; these are also called "pierced belly chains". They are often made of silver or gold. Sometimes a thread is used around the waist instead of a chain. The chain may be delicate and thin, or heavy and thick. Belly chains are considered auspicious for women in Indian culture. History The use of waist chains can be traced back to 4000 years or more originating in the Indian Subcontinent. Historically, waist chains have been used in India, by men and women, as ornaments and as part of religious ceremonies, as accessories and to show affluence.

The Great Chain Today
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun '' the ...
