Tubular Pin Tumbler Lock
A tubular pin tumbler lock, also known as a circle pin tumbler lock, radial lock, or the trademark Ace lock popularized by manufacturer Chicago Lock Company since 1933, is a variety of pin tumbler lock in which a number of pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape. Most locks use between six and eight pins, although some use as few as four or as many as ten. The devices have been widely used on vending machines, elevators, public computers, and bicycle locks. Design The design of a tubular lock is similar to the pin tumbler lock, in that there are several ''stacks'' of pins. The key is a cylinder shape with notches cut around the outer or (rarely) inner edge. Each of these notches depresses a single pin inside the lock to a specific height allowing the ''lock cylinder'' to turn freely. Uses Tubular locks are commonly seen on bicycle locks (such as the Kryptonite lock), Kensington computer locks, elevators, and a var ...

Distal Convoluted Tubule
The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule. Physiology It is partly responsible for the regulation of potassium, sodium, calcium, and pH. On its apical surface (lumen side), cells of the DCT have a thiazide-sensitive Na-Cl cotransporter and are permeable to Ca, via the TRPV5 channel. On the basolateral surface (peritubular capillary side) there is an ATP-dependent Na/K antiporter pump, a secondary active Na/Ca transporter, and an ATP dependent Ca transporter. The basolateral ATP dependent Na/K pump produces the gradient for Na to be absorbed from the apical surface via the Na/Cl symporter, and for Ca to be reclaimed into the blood by the Na/Ca basolateral antiporter. * It regulates pH by absorbing bicarbonate and secreting protons (H+) into the filtrate, or by absorbing protons and secreting bicarbonate into the filtrate. * Sodium and potassium levels are controlled by secreting K+ and absorbing Na ...

Kidney
The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains on ...

Tubular Tyre
A tubular tyre, referred to as a tub in Britain, a sew-up in the US, a single in Australia, or just a tubular is a bicycle tyre that is stitched closed around the inner tube to form a torus. The combination is then glued (sometimes with two-sided tape) onto a specially designed rim, referred to as a "sprint rim" in Britain, and just a "tubular rim" in the US, of a bicycle wheel. Tubular tyres require more labour to repair a puncture than clincher tyres (wired–on in Britain). The tyre must be removed from the rim, opened up, patched, sewn back up, then finally glued back to the rim. Clinchers have largely replaced tubulars for amateur racing (although they have seen a revival due to the carbon rim being better suited to tubular design), but tubulars are still commonly used for indoor track racing (where the closed track makes punctures from road debris less commonplace), professional road racing, road time trials, and cyclo-cross racing. The resulting combination was either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubular-pneumatic Action
"Tubular-pneumatic action" refers to an apparatus used in many pipe organs built during the late 19th and early 20th centuries. The term "tubular" refers to the extensive use of lead tubing to connect the organ's console to the valves that control the delivery of "wind" (air under pressure) to the organ's pipes. Many such organs are extant 100 or more years after their construction. Description In any organ, each pipe has a valve located at its foot which responds to the organist's commands from the console's keyboard, pedalboard and stop controls. These valves are contained in windchests upon which the organ's pipework is set. Any type of apparatus that connects an organ's console with its windchest is referred to as its "action". An organ that utilizes tubular-pneumatic action is commonly called a "tubular-pneumatic organ". It seems the first use of this action was in 1851, in Willis' Great Exhibition organ, though it was only very limited. It appears that the first organ usi ...

Tubular Neighborhood
In mathematics, a tubular neighborhood of a submanifold of a smooth manifold is an open set around it resembling the normal bundle. The idea behind a tubular neighborhood can be explained in a simple example. Consider a smooth curve in the plane without self-intersections. On each point on the curve draw a line perpendicular to the curve. Unless the curve is straight, these lines will intersect among themselves in a rather complicated fashion. However, if one looks only in a narrow band around the curve, the portions of the lines in that band will not intersect, and will cover the entire band without gaps. This band is a tubular neighborhood. In general, let ''S'' be a submanifold of a manifold ''M'', and let ''N'' be the normal bundle of ''S'' in ''M''. Here ''S'' plays the role of the curve and ''M'' the role of the plane containing the curve. Consider the natural map :i : N_0 \to S which establishes a bijective correspondence between the zero section N_0 of ''N'' and the su ...

Tubular NDT
Tubular NDT ( nondestructive testing) is the application of various technologies to detect anomalies such as corrosion and manufacturing defects in metallic tubes. Tubing can be found in such equipment as boilers and heat exchangers. To carry out an examination ''in situ'' (i.e. examination of the tubes in position, where they are installed), a manhole cover is usually removed to allow a technician access to the tubes. Alternatively, a tube bundle may be removed from a heat-exchanger and transported by forklift to a maintenance area for easier access. The usual means of examination is to insert some type of probe into the tubes, one at a time, while data is recorded for later interpretation. The technologies listed below (ECT, RFT, IRIS, and MFL) are all able to detect defects on the outside of the tube from the inside. The tubes must be clean enough to allow passage of the probe: deposits of debris, rust, or scale may have to be removed by chemicals or pressure washing. In water-tu ...

Tubular Gallery
A Tubular Gallery is a large diameter, round, tubular steel structure used to enclose a troughed conveyor belt. It is typically an elevated structure used to span over roadways, rivers or creeks or for use in shiploader systems. Applications Tubular Gallery conveyors are used when a product needs to be isolated from its surrounding environment during transport. Power, cement, petroleum by-product, bio-fuel, coal, agricultural and ship loading are a few of the industries and applications that commonly use Tubular Gallery conveyors. A cost-effective alternative to the Tubular Gallery System is a totally enclosed air supported belt conveyor. Comparison to covered truss conveyors The Tubular Gallery is distinct from covered truss conveyors. Tubular Galleries consist of a completed assembly (which may include the conveyor, air and water piping, lights, and venting) which is assembled in the shop and shipped in completed sections. As a result, it takes much less time and labor to ere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder
A cylinder (from ) has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology. The shift in the basic meaning—solid versus surface (as in ball and sphere)—has created some ambiguity with terminology. The two concepts may be distinguished by referring to solid cylinders and cylindrical surfaces. In the literature the unadorned term cylinder could refer to either of these or to an even more specialized object, the ''right circular cylinder''. Types The definitions and results in this section are taken from the 1913 text ''Plane and Solid Geometry'' by George Wentworth and David Eugene Smith . A ' is a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a fixed plane curve in a p ...

Superleggera
Superleggera (Italian for ''Superlight'') is a custom tube and alloy panel automobile coachwork construction technology developed by Felice Bianchi Anderloni of Italian coachbuilder Carrozzeria Touring Superleggera. A separate chassis was still required. Touring licensed Charles Weymann's system of fabric-covered lightweight frames, which led to Touring’s own superleggera construction. Patented by Carrozzeria Touring in 1936, the superleggera system consists of a structural framework of small-diameter steel tubes that conform to an automobile body's shape and are covered by thin alloy body panels that strengthen the framework. Aside from light weight, the superleggera construction system allows great design and manufacturing flexibility, enabling coachbuilders to quickly construct innovative body shapes. The superleggera tubes were brazed to shape on a jig and the panels were then fitted over this. The panels are only attached at their edges, mostly by swaging the panel ed ...
