"most famous cylinder desk, and perhaps the most famous desk of all times, is the Bureau du Roi manufactured for the French royalty in the 18th century. See also the list of desk forms and types. Cylinder desk The cylinder desk is a desk that resembles a Bureau Mazarin or a writing table equipped with small stacked shelves in front of the user's main work surface, and a revolving cylinder part that comes down to hide and lock up the working papers when the desk is not in use. Like the rolltop desk, which was invented much later, the cylinder"
"James Bond by Q. Procrastinators are cylinders used to store and move time. They vary in size and while the huge ones are used to wind (and unwind) centuries, ""pocket"" procrastinators also exist. They evoke the Tipler cylinder, but are both more versatile and considerably more practical. Devices have so far only appeared in ""Thud!"". Spelt with a capital D, and with enough reverence that it can be heard in speech, 'Device' is the collective term for a variety of artifacts of unknown origin, but with many purposes, all of them of great power and value, such that they are"
"The cittern or cithren (Fr. cistre, It. cetra, Ger. zitter, zither, Sp. cistro, cedra, cítola)[1] is a stringed instrument dating from the Renaissance. Modern scholars debate its exact history, but it is generally accepted that it is descended from the Medieval citole (or cytole). It looks much like the modern-day flat-back mandolin and the modern Irish bouzouki. Its flat-back design was simpler and cheaper to construct than the lute. It was also easier to play, smaller, less delicate and more portable. Played by all classes, the cittern was a premier instrument of casual music-making much as is the guitar today."
"Cylinder A cylinder (from Greek κύλινδρος – ""kulindros"", ""roller, tumbler"") has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. It is the idealized version of a solid physical tin can having lids on top and bottom. This traditional view is still used in elementary treatments of geometry, but the advanced mathematical viewpoint has shifted to the infinite curvilinear surface and this is how a cylinder is now defined in various modern branches of geometry and topology. The shift in the basic meaning (solid versus surface) has created some ambiguity with terminology. It is generally"

This basically worked the same as a percussion revolver, but with only one nipple that sent the ignition spark to a flash hole at the rear of each chamber. Each chamber was loaded in the same manner as the percussion revolvers. Cylinder (firearms) In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chambers. The cylinder revolves around a central axis in the revolver to bring each individual chamber into alignment with the barrel for firing. Each time the gun"

"Cylinder (firearms) In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chambers. The cylinder revolves around a central axis in the revolver to bring each individual chamber into alignment with the barrel for firing. Each time the gun is cocked, the cylinder indexes by one chamber (for five-shooters, by 72°, or for six-shooters, by 60°). Cylinders typically hold six cartridges (hence revolvers sometimes are referred to as ""six-shooters""), but some small-frame revolvers hold only 5 cartridges, due to the smaller overall size of the gun and small available space. The Nagant M1895 revolver has a"
"type of cam was automatic machine tool programming cams. Each tool movement or operation was controlled directly by one or more cams. Instructions for producing programming cams and cam generation data for the most common makes of machine were included in engineering references well into the modern CNC era. This type of cam is used in many simple electromechanical appliance controllers, such as dishwashers and clothes washing machines, to actuate mechanical switches that control the various parts. A cylindrical cam or barrel cam is a cam in which the follower rides on the surface of a cylinder. In the most"

A cylinder is a division of data in a disk drive, as used in the CHS addressing mode of a Fixed Block Architecture disk or the cylinder–head–record (CCHHR) addressing mode of a CKD disk. The concept is concentric, hollow, cylindrical slices through the physical disks (platters), collecting the respective circular tracks aligned through the stack of platters. The number of cylinders of a disk drive exactly equals the number of tracks on a single surface in the drive. It comprises the same track number on each platter, spanning all such tracks across each"

Modern orchestral flutes behave as open cylindrical pipes; clarinets and lip-reed instruments (brass instruments) behave as closed cylindrical pipes; and saxophones, oboes, and bassoons as closed conical pipes. Vibrating air columns also have resonances at harmonics, like strings. Any cylinder resonates at multiple frequencies, producing multiple musical pitches. The lowest frequency is called the fundamental frequency or the first harmonic. Cylinders used as musical instruments are"

The Generation 1 cylinders came in two lengths, only had one input and worked on pressure or vacuum. The Generation 2 cylinders have 2 inputs (and come in studded, studless, and small versions), and work on pressure in both directions. They allow pushing and pulling, depending on which input air is pumped into. Valves have three black, ports on them, and a black Lego axle which controls which of"

The resulting geometric object is three-dimensional anti-de Sitter space. It looks like a solid cylinder in which any cross section is a copy of the hyperbolic disk. Time runs along the vertical direction in this picture. The surface of this cylinder plays an important role in the AdS/CFT correspondence. As with the hyperbolic plane, anti-de Sitter space is curved in such a way that any point in the interior is actually infinitely far"
"cylinder are niches of varying size. Some are self-contained. Others are connected to each other by tunnels. The lost ones can climb into a niche by ladders which are distributed throughout the cylinder. The ladders are often missing rungs at irregular intervals. Most of the lost ones have an irrepressible desire to climb the ladders, and there are large queues around the base of each one, as the lost ones wait their turn to climb. The cylinder has three separate, informal bands of activity. Around the periphery are the climbers waiting for their turns on the ladders. The periphery is"

"Time projection chamber In physics, a time projection chamber (TPC) is a type of particle detector that uses a combination of electric fields and magnetic fields together with a sensitive volume of gas or liquid to perform a three-dimensional reconstruction of a particle trajectory or interaction. The original TPC was invented by David R. Nygren, an American physicist, at Lawrence Berkeley Laboratory in the late 1970s. Its first major application was in the PEP-4 detector, which studied 29 GeV electron–positron collisions at the PEP storage ring at SLAC. A time projection chamber consists of a gas-filled detection volume in an"

The game is played as if the board were a cylinder, with the left side of the board joined to the right side. According to Bill Wall, in 947 in a history of chess in India and Persia, the Arabic historian Ali al-Masudi described six different variants of chess, including astrological chess, circular chess and cylinder chess. Cylindrical board is also used in chess problems. The game is played as if there is no edge on the side of the board. When a piece goes"

"Cylinders are appropriate for 3-D objects that can only rotate about a vertical axis but not about other axes, and are otherwise constrained to move by translation only. Two vertical-axis-aligned cylinders intersect when, simultaneously, their projections on the vertical axis intersect – which are two line segments – as well their projections on the horizontal plane – two circular disks. Both are easy to test. In video games, bounding cylinders are often used as bounding volumes for people standing upright. A is an ellipsoid containing the object. Ellipsoids usually provide tighter fitting than a sphere. Intersections with ellipsoids are done"
"as not to damage the crane. Firearm cylinders were first developed in the 16th century and, over time, had anywhere from three to twelve chambers bored into them. One of the earliest examples is dated 1587. Cylinders were developed as a device to increase the multiple-fire capability of firearms. Firearms of the period were mostly muskets and only capable of firing a single shot before needing to be reloaded. Reloading the single-shot firearm was time-consuming and in a military or self-defense situation where seconds mattered, this rendered it almost useless after the first shot. A firearm with several pre-loaded chambers"

"Graduated cylinder A graduated cylinder, measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. Large graduated cylinders are usually made up of polypropylene for its excellent chemical resistance or polymethylpentene for its transparency, making them lighter and less fragile than glass. Polypropylene (PP) is easy to repeatedly autoclave; however, autoclaving in excess of about (dependinal grade polypropylene melts in excess of ), can warp or damage polypropylene"
