Lock (security Device)
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the ''bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to ope ...

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 ...

Bulk Vending
Bulk vending is the sale of unsorted confections, nuts, gumballs, toys and novelties (in capsules) selected at random and dispensed generally through non-electrically operated vending machines. Bulk vending is a separate segment of the vending industry from full-line vending — i.e., the snack and soda vending industries — and involves different products and strategies. Bulk vending represents less than 1% of the total vending industry. History Bulk vending dates back at least to the late 19th century. Vending machines were widely used in Europe before they became popular in the United States. In the early 1880s, the first commerciacoin-operated venderwas introduced in London and stocked with postcards. In 1888, the Thomas Adams Gum Co. introduced bulk venders to America, using the machines to sell Tutti frutti gum on elevated subway platforms in New York City. In 1897, the Pulver Manufacturing Company added animated figures to its gum machines. In 1907, the round, candy-coated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
