A solid body which may be generated by the rotation of a parallelogram round one its sides; or a body of rollerlike form, of which the longitudinal section is oblong, and the cross section is circular.

The chamber of a steam engine in which the piston is moved by the force of steam.

The barrel of an air or other pump.

The bore of a gun; the turning chambered breech of a revolver.

On a hard disk, a cylinder is all the tracks on all the disk platters that lie in the same relative position.

Two or more tracks which lie on the same location on a disk.

The same track from each platter of a disk. See also platter.

When disks are placed directly above one another along the shaft, the circular, vertical "slice" consisting of all the tracks located in a particular position.

The revolving platen or bed which produces the impression or carries the type in a cylinder press.

The revolving square prism carrying the cards in a Jacquard loom.

A three dimensional shape shaped like a trash can.

A space figure that has congruent circles for 2 faces.

The space inclosed by any cylindrical surface. The space may be limited or unlimited in length.

a solid bounded by a cylindrical surface and two parallel planes (the bases)

a surface generated by rotating a parallel line around a fixed line

a surface generated by a family of all lines

Printing blocks are placed on a cylinder and each turn of the cylinder prints one image. The circumference of the cylinder dictates the bag width or height.

number Letters/numerals in sheet margins identifying printing cylinders. Normally collected in 'Cylinder block' of six stamps. (See also Plate number).

In flexography, for no particular reason, most rollers in the printing presses are called rolls with the exception of that upon which the rubber plates are mounted, and the one which receives the impression, and these are usually referred to as cylinders, e.g.: plate cylinders or impression cylinder.

a cylindrical container for oxygen or compressed air

a tall narrow container with a volume scale used especially for measuring liquids

A propane gas (LPG) container. The ones used in hot air balloons are crude, lightweight versions measuring approx. 90cm high, approx. 30cm in diameter, with a gross weight of approximately 32kg. One cylinder can be filled with 19.5kg of Liquid Propane D d

Portable and refillable vessel of approved design used to contain LPG under pressure.

term indiscriminately applied to various kinds of rolls or drums on papermachines. More particularly the steam heated cylinders for drying paper.

The portion of your paramotor that gets hot. (Also avoid touching the exhaust) Paramotors are typically two stroke air cooled engines. They can develop in excess of 25 horse power.

See Barrel. Degassing – Evacuation of air, steam or volatile compound through an orifice located in the barrel. The degassing can be forced by using a vacuum pump.

A hollow cylindrical-shaped device in which the power of a reciprocating engine is developed. In the case of a steam engine, it is here that the power of the steam is converted to mechanical motion.

The outermost lining of a hydraulic ram.

a device that converts fluid power into linear mechanical force and motion.

Also referred to as a "linear motor," it is a device that converts pneumatic power into linear (in a line) or reciprocating (back-and-forth) motion.

The outermost lining of a hydraulic jack.

a lens which has refractive power only in one meridian but not at right angle to it

meridian in ophthalmology, a line that is the symmetrical center of a curved optical surface. Also a measure of astigmatism.

The amount of lens power necessary to compensate for astigmatism

a pretty good shape to move through the air because it develops a nice laminar air flow that reduces drag

a shape that has ellipses for its top and bottom faces

a shape that looks like a column
