Gun Laying Radars
A gun is a device that propels a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns or cannons), or gas (e.g. light-gas gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Tasers, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. Guns were designed as weapons for military use, and then found use in hunting. Now, there are guns, e.g., toy guns, water guns, paintball guns, etc., for many purposes. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within a barrel tube (gun barrel), produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toy Gun
Toy guns are toys which imitate gun, real guns, but are designed for recreational sport or casual play by children. From hand-carved wooden replicas to factory-produced pop guns and cap guns, toy guns come in all sizes, prices and materials such as wood, metal, plastic or any combination thereof. Many newer toy guns are brightly colored and oddly shaped to prevent them from being mistaken for real firearms. Types Wooden guns Wooden guns are made to resemble real guns. Often handmade, these toys may or may not have metal parts and are made with various levels of detail. Suction cup darts Suction cup dart toy pistols are made to resemble real pistols, used to fire one suction cup Dart (missile), dart. Rubber band guns Rubber band guns are toy guns used to fire one or more rubber bands (or "elastic bands"). Rubber band guns are often used in live-action games such as Assassins (game), Assassins, in which they are common and popular toy weapons. They are also common in offices ...

Guide Rail
A guide rail is a device or mechanism to direct products, vehicles or other objects through a channel, conveyor, roadway or rail system. Several types of guide rails exist and may be associated with: * Factory or production line conveyors * Power tools, such as table saws * Elevator or lift shafts * Roadways and bridges (in this context sometimes called Guard rails (railroad), guardrails) * A central rail that guides the rubber tired train of a Rubber-tyred metro#Technology, rubber tired metro Factory guide rail Most factories use guide rails convey products and component parts along an assembly line. This conveyor system propels products of various sizes, shapes, and dimensions through the factory over the course of their assembly. Power tool guide rail Accessory to a power tool, such as a straight, swivel or angle jig for a circular saw, and can also be referred to as a fence. The guide rail system provides an acute method of cutting material. Elevator shaft guide rail Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
