What is "tube"

Subway \Sub"way`\, n.

1. An underground way or gallery; especially, a passage under a street, in which water mains, gas mains, telegraph wires, etc., are conducted.

2. An underground railroad, usually having trains powered by electricity provided by an electric line running through the underground tunnel. It is usually confined to the center portion of cities; -- called also tube, and in Britain, underground. In certain other countries (as in France or Russia) it is called the metro.

1610s, from Middle French tube (15c.), from Latin tubus "tube, pipe," of unknown origin. The London subway was christened the Twopenny Tube (H.D. Browne, in the "Londoner" of June 30, 1900) before it even opened; tube for "cylindrical railway tunnel" is attested from 1847. The meaning "TV as a medium" is from 1959, short for cathode ray tube or picture tube. Tube top as a women's clothing style is attested from 1972. Tube steak is attested from 1963 as "frankfurter," slang meaning "penis" is recorded by mid-1980s.

n. 1 Anything that is hollow and cylindrical in shape. 2 An approximately cylindrical container, usually with a crimped end and a screw top, used to contain and dispense semi-liquid substances. 3 (lb en British colloquial often capitalized as Tube) The London Underground railway system, originally referred to the lower level lines that ran in tubular tunnels as opposed to the higher ones which ran in rectangular section tunnels. (Often ''the tube''.) 4 (lb en Australia slang) A tin can containing beer (or other beverage?).(attention en topic=Australian English) 5 (lb en surfing) A wave which pitches forward when breaking, creating a hollow space inside. 6 (lb en North America colloquial) A television.

Tube, or Tubes, may refer to:

is a Japanese pop rock band formed in 1985. The members of the group are , and . Tube members Maeda and Haruhata have composed for other artists under the Pipeline Project alias. Since the group released most of its songs in April to July, the catchphrase originated "Summer comes with Tube".

In computing, the Tube was the expansion interface and architecture of the BBC Microcomputer System which allowed the BBC Micro to communicate with a second processor, or coprocessor.

Under the Tube architecture, the coprocessor would run the application software for the user, whilst the Micro (acting as a host) provided all I/O functions, such as screen display, keyboard and storage devices management. A coprocessor unit could be coldplugged into any BBC Micro with a disk interface (whose ROM contained the necessary host software) and used immediately.

In structural engineering, the tube is the system where in order to resist lateral loads (wind, seismic, etc.) a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. This system was introduced by Fazlur Rahman Khan while at Skidmore, Owings and Merrill's (SOM) Chicago office. The first example of the tube’s use is the 43-story Khan-designed DeWitt-Chestnut Apartment Building in Chicago, Illinois, completed in 1963.

The system can be constructed using steel, concrete, or composite construction (the discrete use of both steel and concrete). It can be used for office, apartment and mixed-use buildings. Most buildings in excess of 40 stories constructed since the 1960s are of this structural type.

Tube is a 2003 South Korean action thriller film directed by Beak Woon-hak (or Baek Woon-hak). The film features police officer Jay ( Kim Suk-hoon) who is a subway police officer who spends his days reminiscing over his lost lover. The pickpocket Kay ( Bae Doona) becomes infatuated with Jay and tips him off about the government assassin Bishop ( Park Sang-min) hijacking a subway car. Both Jay and Kay find themselves in the target car when the Bishop makes his move.

Tube is usually known as a toy that assists plays on water. Most of these are manufactured in a figure like a doughnut, but there are also variant forms of tubes like boat and fish are on markets and waterparks.

A tube is a soft squeezable container which can be used for thick liquids such as adhesive, caulking, ointment, and toothpaste. Basically, a tube is a cylindrical, hollow piece with a round or oval profile, made of plastic, paperboard, or aluminum. Both ends of this tube are treated differently during the manufacturing process and filling. In general, on one end of the tube body there is a round orifice, which can be closed by different caps and closures. The orifice can be shaped in many different ways. Plastic nozzles in various styles and lengths are just one good example.

To attach caps and closures, in most cases a thread is tapped onto the opening structure. Furthermore, something all aluminium tubes have in common is that the other open end is folded several times after the contents have been added. The tube is thus hermetically sealed and nearly germ-free due to the high temperatures during the production process. Furthermore, it is possible to coat the inside of the tube with special coatings to prevent the material from reacting with the contents.

Tubes are not poured from liquid aluminium; they are produced by the process of impact extrusion. In this process, the tube body is extruded from a small piece of aluminium with the round shape of a coin.

Unlimited printing designs can be applied to the tube, thanks to the wet-in-wet offset printing method. Six tones can be printed with this printing procedure, which gives packaging designers great opportunities to express their creativity.

The filled content can be easily squeezed out by the pressure of two fingers. The main characteristic of aluminium tubes is the total separation of the contents from the surrounding atmosphere; therefore, such tubes are especially suitable for the packaging of highly perishable contents. Aluminium tubes are used as packaging technology for cosmetics, pharmaceuticals, food, and technical products.

Plastic Tubes : Tube containers can also be produced in plastic, most commonly PE. The use of plastic tubes is very popular for the storage of Cosmetics such as hand creams etc. and also some food stuffs. The plastic tube retains its shape after each "squeeze" unlike laminate tubes such as toothpaste tubes. Plastic tubes can also be highly decorated or have a special additive such as soft touch to make the tube more appealing during use or point of sale (POS).

Plastic tubes are produced using the extrusion process. A "sleeve" is first produced using a very specialised extrusion line. The "Sleeve" must be produced to a very high standard (for decoration purposes) and also to very tight tolerances as automated processes are required post the extrusion operation. Once the "sleeve" is produced the tube head is fitted using an automated heading machine. Tube printing using complex and specialised printing machines such as silk screen printing applies the desired decoration. The open tubes are then most likely packed and despatched to another facility for filling and sealing.

The growth of multi-layer plastic tubes has been significant over the last couple of years due to the "barrier" properties of the tube to enable a wider range of products such as food to be stored in them.

A tube, or tubing, is a long hollow cylinder used for moving fluids ( liquids or gases) or to protect electrical or optical cables and wires.

The terms " pipe" and "tube" are almost interchangeable, although minor distinctions exist — generally, a tube has tighter engineering requirements than a pipe. Both pipe and tube imply a level of rigidity and permanence, whereas a hose is usually portable and flexible. A tube and pipe may be specified by standard pipe size designations, e.g., nominal pipe size, or by nominal outside or inside diameter and/or wall thickness. The actual dimensions of pipe are usually not the nominal dimensions: A 1-inch pipe will not actually measure 1 inch in either outside or inside diameter, whereas many types of tubing are specified by actual inside diameter, outside diameter, or wall thickness.
