Abstract: The system controls the dispensing of beverages in a bar. The system has individual manually actuated beverage dispensers equipped with electrically controlled flow valve devices which meter and dispense variable amounts of beverages upon command by a user. The system is provided with a key pad offering a selection of beverage mixes. A control device is connected to the beverage dispensers and the key pad for recording use of the beverage dispensers by the user, and for causing the flow valve devices of the dispensers used to make up a beverage mix selected on the key pad to dispense the amounts of beverage prescribed for the selected beverage mix. The controller provides for a controlled use of the beverage dispensers for preparing a beverage mix selected on the key pad in addition to a direct manual use of the beverage dispensers by the user.

Abstract: A non-contact coding device working in a magnetic field, for use with a liquor bottle stopper and electromagnetic valve system. The stopper can be provided with a secondary coil and a diode bridge/rectifier circuit for powering a serial number identifier chip, which serially varies the impedance of the secondary coil. A primary coil on activator unit is coupled with the secondary coil to provide power and read the serial number. The activator unit can also be provided with a number of Hall effect transducers, and the stopper a number of metal peg holes, such that when the transducers are aligned on top of the holes, the presence/absence of metal pegs can be read to reproduce the serial number.

Abstract: The rack comprises a pair of rails for slidingly holding a neck of a bottle and a turnstile at the entrance to the rails. A control signal is generated each time the turnstile is moved as a bottle is placed onto the rack or removed from the rack. The rack is easily adapted and installed into existing refrigeration units, is tamper proof and inexpensive to manufacture.
