ABSTRACT:
Each open liquor bottle in a tavern has a plastic spout with a magnetically operable valve to control the flow of liquor from the bottle. The spouts were fabricated with three integral rings extending around the spout with each ring being either plastic or metal to form a pattern that encodes information identifying a characteristic of the bottle. An annular actuator reads the pattern of rings and responds by producing a magnetic field that opens the spout valve to dispense the liquor. Three rings allow up to eight different classes of characteristics to be encoded. To increase that number of classes a supplemental metal ring is attached around some of the spout adjacent to one end of the actuator when the spout is inserted therein. The actuator is modified to sense presence of the supplemental metal ring on a spout. Adding another ring to certain spouts permits the number of classes of characteristics to be doubled without requiring replacement of existing spouts in a tavern.
