Bobbin
A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. Bobbins are typically found in industrial textile machinery, as well as in sewing machines, fishing reels, tape measures, film rolls, cassette tapes, within electronic and electrical equipment, and for various other applications. Industrial textiles Bobbins are used in spinning, weaving, knitting, sewing, and lacemaking. In these practices, bobbins were invented to "manage the piles of thread and yarn that would be mechanically woven into cloth," which would have originally been wound through the use of human power, but which eventually became machine-driven. In these applications, bobbins provide storage, temporary and permanent, for yarn or thread. Historically, bobbins were made out of natural materials such as wood, or bone. While not in principle an invention of the Victorian era - bobbins in the production of textiles were in earlier use - th ...

Cable Reel
A cable reel is a round, drum-shaped object such as a spool used to carry various types of electrical wires. Cable reels, which can also be termed as drums, have been used for many years to transport electric cables, fiber optic cables and wire products. Cable reels usually come in four different types, each with their own uses: wood, plywood, plastic and steel. Wooden drums Wooden drums come in three different varieties: steel-tyred for multiple use, export for sending abroad, and one-way drums for single trip use. Wooden drums can carry heavy loads and are constructed in resinous wood. Discarded wooden reels can often be obtained cheaply and are, owing to their shape, commonly used as furniture (usually coffee tables) for college students and others seeking inexpensive furnishings. Plywood drums/reels Plywood reels are used for transporting lighter loads and are a cheaper alternative to other types of drums, used extensively in the building industry and by commercial e ...

Spool (record Label)
Spool is a Canadian record label which was founded 1997 in Peterborough, Ontario, Canada. Their first releases were in 1998. They relocated to Uxbridge, Ontario in 1999. The name comes from the play by Samuel Beckett: ''Krapp's Last Tape''. In the play, Krapp becomes fascinated by the word "spool" and repeats it several times. On December 27, 2001, Spool was given national notice in an article in ''The Globe and Mail'' by Canadian jazz critic Mark Miller, who said "It's work supported not by the majors, but by smaller companies – as small as Uxbridge, Ont., label Spool which released two of the most interesting Canadian CDs of 2001, West Coast guitarist Tony Wilson's melancholic ''Lowest Note'' and a boisterous collaboration between George Lewis and Vancouver's NOW Orchestra, ''The Shadowgraph Series.''" Spool releases also received reviews in the Toronto Star by Geoff Champman, as well as Coda (magazine), DownBeat, Vancouver Province, La Scena musicale, The Wire (magazine), ...

Spooling
In computing, spooling is a specialized form of multi-programming for the purpose of copying data between different devices. In contemporary systems, it is usually used for mediating between a computer application and a slow peripheral, such as a printer. Spooling allows programs to "hand off" work to be done by the peripheral and then proceed to other tasks, or to not begin until input has been transcribed. A dedicated program, the spooler, maintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. Conversely, for slow ''input'' peripherals, such as a card reader, a spooler can maintain a sequence of computational jobs waiting for data, starting each job when all of the relevant input is available; see batch processing. The spool itself refers to the sequence of jobs, or the storage area where they are held. In many cases, the spooler is able to drive devices at their full rated speed with minimal impact on other processing. Spooling is a ...

The Spooler
''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 ''thee'') ...

Spool (aeronautics)
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together. Engines that use more jet thrust relative t ...

Locking Differential
A locking differential is a mechanical component, commonly used in vehicles, designed to overcome the chief limitation of a standard open Differential (mechanical device), differential by essentially "locking" both wheels on an axle together as if on a common shaft. This forces both wheels to turn in unison, regardless of the traction (or lack thereof) available to either wheel individually. When the differential is unlocked (open differential), it allows each wheel to rotate at different speeds (such as when negotiating a turn), thus avoiding tire scuffing. An open (or unlocked) differential always provides the same torque (rotational force) to each of the two wheels on that axle. Therefore, although the wheels can rotate at different speeds, they apply the same rotational force, even if one is entirely stationary, and the other spinning (equal torque; unequal rotational speed). By contrast, a locked differential forces both left and right wheels on the same axle to rotate at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and analogue computers. Differentials can also provide a gear ratio between the input and output shafts (called the "axle ratio" or "diff ratio"). For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear. History Milestones in the design or use of differentials include: * 100 BCE–70 BCE: The Antikythera mechanism has been dated to this period. It was discovered in 1902 on a shipwreck by sponge divers, and modern research suggests that it used a differential gear to determine the angle between the ecliptic positions of the Sun and Moon, and thus the phase of the Moon. ...

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension (physics), tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a Bobbin, spool (or drum) attached to a hand crank (mechanism), crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called Capstan_(nautical), capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted.
