Shackling
A shackle (or shacklebolt), also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner. Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks. A carabiner is a type of shackle used in mountaineering. Types Bow shackle With a larger "O" shape to the loop, this shackle can take loads from many directions without developing as much side load. However, the larger shape to the loop does reduce its overall strength. Also referred to as an anchor shackle. D-shackle Also known as a chain shackle, ...

Mannheim Germany Shackles-in-a-workshop-01
Mannheim (; Palatine German: or ), officially the University City of Mannheim (), is the second-largest city in Baden-Württemberg after Stuttgart, the state capital, and Germany's 21st-largest city, with a population of over 315,000. It is located at the border with Rhineland-Palatinate. The city is the cultural and economic centre of the Rhine-Neckar, Germany's seventh-largest metropolitan region, with nearly 2.4 million inhabitants. Mannheim is located at the confluence of the Upper Rhine and the Neckar in the Kurpfalz (Electoral Palatinate) region of northwestern Baden-Württemberg. The city lies in the Upper Rhine Plain, Germany's warmest region, between the Palatine Forest and the Oden Forest. Mannheim forms a continuous urban zone of around 500,000 inhabitants with Ludwigshafen am Rhein in the Rhineland-Palatinate, while some northern suburbs lie in Hesse. Hamburg is the only other German city with such a presence in two states other than its own. Surrounded by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clevis
A clevis fastener is a two-piece fastener system consisting of a ''clevis'' and a ''clevis pin head''. Terms The ''clevis'' is a U-shaped piece that has holes at the end of the prongs to accept the clevis pin. The ''clevis pin'' is similar to a Bolt (fastener), bolt, but is either partially threaded or unthreaded with a cross-hole for a split pin. A ''tang'' is a piece that is sometimes fitted in the space within the clevis and is held in place by the clevis pin. The combination of a simple clevis fitted with a pin is commonly called a ''shackle,'' although a clevis and pin is only one of the many forms a shackle may take. Usage Clevises are used in a wide variety of fasteners used in Agriculture, farming equipment and sailboat rigging, as well as the automotive, aircraft and construction industries. They are also widely used to attach Flight control surfaces, control surfaces and other accessories to servo controls in Model aircraft#Flying model aircraft, airworthy model aircraf ...

Marlinspike
A marlinspike (, sometimes spelled marlin spike, marlinespike, or rchaicmarlingspike) is a tool used in marine ropework. Shaped in the form of a narrow metal cone tapered to a rounded or flattened point, it is used in tasks such as unlaying rope for splicing, untying knots, drawing tight using a marlinspike hitch, and as a toggle joining ropes under tension in a belaying pin splice. Marlinspikes are usually about long but may reach or more when used for working heavy cables and ropes. They are usually made from iron or steel, whereas fids, similar in shape and function, are formed from wood or bone. Historically a separate tool, the marlinspike is integrated in specialized versions of folding rigging and pocket knives. Sailors who become proficient at knot tying, splicing, and sewing using the marlinspike are said to have mastered marlinespike seamanship, earning them the right to be known as ''marlin spikes'' or ''marlinspike seamen''. Uses Marlinspikes are used: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanolin
Lanolin (from Latin 'wool', and 'oil'), also called wool fat, wool yolk, wool wax, sheep grease, sheep yolk, or wool grease, is a wax secreted by the sebaceous glands of wool-bearing animals. Lanolin used by humans comes from domestic sheep breeds that are raised specifically for their wool. Historically, many pharmacopoeias have referred to lanolin as wool fat ('' adeps lanae''); however, as lanolin lacks glycerides (glycerol esters), it is not a true fat. Lanolin primarily consists of sterol esters instead. Lanolin's waterproofing property aids sheep in shedding water from their coats. Certain breeds of sheep produce large amounts of lanolin. Lanolin's role in nature is to protect wool and skin from climate and the environment; it also plays a role in skin ( integumental) hygiene. Lanolin and its derivatives are used in the protection, treatment, and beautification of human skin. Composition A typical high-purity grade of lanolin is composed predominantly of long chain ...

Galling
Galling is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together. Galling is caused by a combination of friction and adhesion between the surfaces, followed by slipping and tearing of crystal structure beneath the surface. This will generally leave some material stuck or even friction welding, friction welded to the adjacent surface, whereas the galled material will appear worn, chipped, or even gouged and may have balled-up or torn lumps of material stuck to its surface. Galling is most commonly found in metal surfaces that are in sliding contact with each other. It is especially common where there is inadequate lubrication between the surfaces. However, certain metals will generally be more prone to galling, due to the atomic structure of their crystals. For example, aluminium will gall very easily, whereas annealed ...

Tap And Die
In the context of threading, taps and dies are the two classes of tools used to create screw threads. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called ''tapping'', whereas the process using a die is called ''threading''. Both tools can be used to clean up a thread, which is called ''chasing''. However, using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies—called '' chasers''—made for that purpose. Chasers are made of softer materials and don't cut new threads. However they still fit tighter than actual fasteners, and are fluted like regular taps and dies so debris can escape. Car mechanics, for example, use ch ...

Threading (manufacturing)
In manufacturing, threading is the process of creating a screw thread. More screw threads are produced each year than any other machine element. There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive manufacturing, additive methods (such as 3D printing); or combinations thereof. Overview of methods (comparison, selection, etc.) There are various methods for generating screw threads. The method for any one application is chosen based on constraints—time, money, degree of precision needed (or not needed), what equipment is already available, what equipment purchases could be justified based on resulting unit price of the threaded part (which depends on how many parts are planned), etc. In general, certain thread-generating processes tend to fall along certain portions of the spectrum from toolroom-made parts ...

Moused Shackle
moused is a mouse daemon on FreeBSD systems that works with the console driver to support mouse operations in the text console and user programs. It first appeared in FreeBSD 2.2 and is currently located in /usr/sbin/moused. Function The mouse daemon listens to a mouse port (by default, /dev/psm0) and supplies mouse data to a virtual mouse driver, sysmouse(4). A user process that wants to use the mouse simply opens /dev/sysmouse and reads from it like a normal file. This makes it possible for the console and user processes such as the X Window System to share the mouse. PS2 mice will not need configuration while serial-port mice will. Multiple mice can be used at once by starting multiple moused instances. See also * GPM References External links moused(8) FreeBSD man page A man page (short for manual page) is a form of software documentation found on Unix and Unix-like operating systems.

Sheet (sailing)
In sailing, a sheet is a line (rope, cable or chain) used to control the movable corner(s) (clews) of a sail. Terminology In nautical usage the term "sheet" is applied to a line or chain attached to the lower corners of a sail for the purpose of extension or change of direction. The connection in derivation with the root "shoot" is more clearly seen in "sheet-anchor", one that is kept in reserve, to be "shot" in case of emergency. Fore-and-aft rigs Fore-and-aft rigs comprise the vast majority of sailing vessels in use today, including effectively all dinghies and yachts. The sheet on a fore-and-aft sail controls the angle of the sail to the wind, and should be adjusted to keep the sail just filled. Most smaller boats use the Bermuda rig, which has two or three sets of sheets: * The mainsheet is attached to the boom, and is used to control the mainsail. In a rig with no boom on the mainsail, the mainsheet would attach directly to the mainsail clew. A mainsheet is a line con ...

Spinnaker
A spinnaker is a sail designed specifically for sailing off the wind on courses between a Point of sail#Reaching, reach (wind at 90° to the course) to Point of sail#Running downwind, downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be ''flown''. Etymology Some dictionaries suggest that the origin of the word could be traced to the first boat to commonly fly a spinnaker, a yacht called ''Sphinx'', mispronounced as ''Spinx''. ''Spinnaker'' entry in The Concise Oxford Dictionary of English Etymology (1996). Oxford University PressAccording to encyclopedia.com Both retrieved on 20 July 2008.

Safety Harness
A safety harness is a form of Personal protective equipment, protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, Wire rope, braided wire cable, or Webbing, synthetic webbing. It is attached securely to a stationary object directly by a Carabiner, locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a Shock absorber, shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached. An unrelated use with a materially different arresting mechanism is bungee jumping. Though they share certain similar attributes, a safety harness is not to be confused with a climbing harness used for mountaineering, rock climbing, and Climbing gym, climbing gyms.
