Spinner (aeronautics)
A spinner is an aircraft component, a streamlined fairing fitted over a propeller hub or at the centre of a turbofan engine. Spinners both make the aircraft overall more streamlined, thereby reducing aerodynamic drag, and also smooth the airflow so that it enters the air intakes more efficiently. Spinners also fulfill an aesthetic role on some aircraft designs.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 480. Aviation Supplies & Academics, 1997.

Ten-pin Bowling
Ten-pin bowling is a type of bowling in which a bowler rolls a bowling ball down a wood or synthetic lane toward ten pins positioned evenly in four rows in an equilateral triangle. The objective is to knock down all ten pins on the first roll of the ball (a strike), or failing that, on the second roll (a spare). An approximately long ''approach'' area used by the bowler to impart speed and apply rotation to the ball ends in a ''foul line''. The , lane is bordered along its length by ''gutters'' (''channels'') that collect errant balls. The lane's long and narrow shape limits straight-line ball paths to angles that are smaller than optimum angles for achieving strikes; accordingly, bowlers impart side rotation to ''hook'' (curve) the ball into the pins to increase the likelihood of striking. Oil is applied to approximately the first two-thirds of the lane's length to allow a "skid" area for the ball before it encounters friction and hooks. The oil is applied in different leng ...

Spinor
In geometry and physics, spinors are elements of a complex vector space that can be associated with Euclidean space. Like geometric vectors and more general tensors, spinors transform linearly when the Euclidean space is subjected to a slight (infinitesimal) rotation. Unlike vectors and tensors, a spinor transforms to its negative when the space is continuously rotated through a complete turn from 0° to 360° (see picture). This property characterizes spinors: spinors can be viewed as the "square roots" of vectors (although this is inaccurate and may be misleading; they are better viewed as "square roots" of sections of vector bundles – in the case of the exterior algebra bundle of the cotangent bundle, they thus become "square roots" of differential forms). It is also possible to associate a substantially similar notion of spinor to Minkowski space, in which case the Lorentz transformations of special relativity play the role of rotations. Spinors were introduced in geome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinner Shark
The spinner shark (''Carcharhinus brevipinna'') is a species of requiem shark, in the family Carcharhinidae, named for the spinning leaps it makes as a part of its feeding strategy. This species occurs in tropical and warm temperate waters worldwide, except for in the eastern Pacific Ocean. It is found from coastal to offshore habitats to a depth of , though it prefers shallow water. The spinner shark resembles a larger version of the blacktip shark (''C. limbatus''), with a slender body, long snout, and black-marked fins. This species can be distinguished from the blacktip shark by the first dorsal fin, which has a different shape and is placed further back, and by the black tip on the anal fin (in adults only). It attains a maximum length of . Spinner sharks are swift and gregarious predators that feed on a wide variety of small bony fishes and cephalopods. When feeding on schools of forage fish, they speed vertically through the school while spinning on their axis, erupting fr ...

Spinner Dolphin
The spinner dolphin (''Stenella longirostris'') is a small dolphin found in off-shore tropical waters around the world. It is famous for its acrobatic displays in which it rotates around its longitudinal axis as it leaps through the air. It is a member of the family Delphinidae of toothed whales. Taxonomy The spinner dolphin is sometimes referred to as the long-snouted dolphin, particularly in older texts, to distinguish it from the similar Clymene dolphin, which is often called the short-snouted spinner dolphin. The species was described by John Gray in 1828. The four named subspecies are: *Eastern spinner dolphin (''S. l. orientalis''), from the tropical eastern Pacific. *Central American or Costa Rican spinner dolphin (''S. l. centroamericana''), also found in the tropical eastern Pacific. *Gray's or Hawaiian spinner dolphin (''S. l. longirostris''), from the central Pacific Ocean around Hawaii but represents a mixture of broadly similar subtypes found worldwide. *Dwarf spin ...

Whirligig
A whirligig is an object that spins or whirls, or has at least one part that spins or whirls. It can also be a pinwheel, spinning top, buzzer, comic weathervane, gee-haw, spinner, whirlygig, whirlijig, whirlyjig, whirlybird, or simply a whirly. They are most commonly powered by the wind but can be hand-, friction- or motor-powered. They can be used as kinetic garden ornaments, and can be designed to transmit sound and vibration into the ground to repel burrowing rodents. Types Whirligigs can be divided into four categories: button, friction, string and wind-driven. Button whirligigs Button whirligigs, also known as button spinners and buzzers, are the oldest known whirligigs. They require only a piece of clay or bone and a strip of hide. The ancient Greeks had their own version of this toy, called an ''iynx'', and Native American cultures had another in 500 BC. Many a child of the Great Depression from the southern Appalachians and Ozarks remembers a button or token, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spin Coating
Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. The substrate is then rotated at speed up to 10,000 rpm to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent is usually volatile, and simultaneously evaporates. The higher the angular speed of spinning, the thinner the film. The thickness of the film also depends on the viscosity and concentration of the solution, and the solvent. Pioneering theoretical analysis of spin coating was undertaken by Emslie et al., and has been extended by many subsequent authors (including Wilson et al., who studied the rate of spreading in spin coati ...

Midland Railway 115 Class
The Midland Railway 115 Class was the third of four classes of 4-2-2 steam locomotive, nicknamed "Spinners", designed by Samuel Waite Johnson. A total of 15 of the class were built between 1896 and 1899. They were capable of reaching speeds of up to 90 miles per hour (145 km/h).. One engine, No. 673, is preserved in the National Collection. Classes of Midland Railway 4-2-2 locomotives Single-driver locomotives had been superseded in the late 19th century as loads increased, but were then reintroduced when steam sanding allowed better adhesion. Five similar classes were built, with slight enlargements each time, and details as follows: Construction history The fifteen locomotives in the 115 class were built in two batches, both at Derby Works. Service history It was quite common for engines of this class to pull a typical Midland express weighing , which suited the Class 115 perfectly. Given a dry rail they could maintain a tight schedule with . Speeds up to 90 mph wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinner (wheel)
The spinner on automobile wheels historically refers to knock-off hub nuts or center caps. They may be the actual, or intended to simulate, the design used on antique vehicles or vintage sports cars. A "spinner wheel" in contemporary usage is a type of hubcap or inner wheel ornament, that spins independently inside of a wheel itself when the vehicle is in motion, and continues to spin once the vehicle has come to a stop. Original use The spinner or "knock-off" originated with Rudge-Whitworth centerlock Wire wheel, wire wheels and hubs, which were first patented in 1908. The spinner was a threaded, winged nut designed to keep the wheel fastened to the hub. They were screwed on and "knocked on tightly" using a hammer, hence the name "knock-offs". Most setups will feature right-hand threads on the left side of the vehicle, and left-hand threads (rotate clockwise to remove) on the vehicle's right side so the screw-on spinner would stay tightened as the auto was in forward motion. ...

Spinner (website)
Spinner was an online music and entertainment service. An AOL Music property, it was acquired by AOL on June 1, 1999, along with Nullsoft for $400 million. Based in San Francisco, California, the website was the first Internet music service and was the largest by 2001, while offering promotional features from high-profile recording artists. In 2002, AOL combined Spinner with the former's Netscape portal to form Netscape Radio. Spinner broadcast over 100 radio stations, including Radio CMJ. In 2008, Spinner was revamped by AOL as a music website aimed at the "music aficionado". The website offers exclusive interviews of recording artists, streams of albums and live performances, and a free music download daily. Spinner, along with all AOL music sites, was abruptly shut down in April 2013. The URLs to all former AOL music sites, including Spinner, were re-directed to aolradio.slacker.com starting in August 2013. Several AOL Music blogs, along with Comics Alliance, were sold to Town ...

Spinnerbait
A spinnerbait or spinner is any one of a family of hybrid fishing lures that combines the designs of a swimbait with one or more spoon lure blades. Spinnerbaits get the name from the action of the metallic blades, which passively revolve around the attachment point like a spinning propeller when the lure is in motion, creating varying degrees of vibration and flashing that mimic small fish or other preys of interest to large predatory fishes. The two most popular types of spinnerbaits are the ''in-line spinner'' and ''safety pin spinnerbait'', though others such as the ''tail spinner'' also exist. Spinnerbaits are used principally for catching freshwater fishes such as perch, pike and bass. Mode of operation Spinnerbaits attract predatory fish primarily by creating significant amount of turbulence, noise and flashing reflections with the spinning blade. The turbulence waves, in particular, provoke the fish's lateral line system, a special tactile sensory organ that enables fis ...

Article Spinning
Article spinning is a writing technique used in search engine optimization (SEO), and other applications, which creates what deceitfully appears to be new content from what already exists. Content spinning works by replacing specific words, phrases, sentences, or even entire paragraphs with any number of alternate versions, in order to provide a slightly different variation with each spin — also known as Rogeting. This process can be completely automated or written manually as many times as needed. Early content produced through automated methods often resulted in articles which were hard or even impossible to read. However, as article-spinning techniques were refined they became more sophisticated, and can now result in readable articles which, upon cursory review, can appear original. The practice is sometimes considered falling under the category of spamdexing, a black hat SEO practice, given that no genuinely new content is created. Website authors use article spinning to r ...
