  • Patent number: 5702032
    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.

  • Patent number: 5494112
    Abstract: A fire fighting system introduces a liquid chemical foam concentrate into a water stream. The system may incorporate either or both of a hydraulic motor driven pump under control of a microprocessor-based hydraulic valve driver and an electric motor driven pump under control of a DC motor drive circuit. The DC motor drive circuit is adapted to be connected in electrical communication with the hydraulic valve driver and with a display/controller also incorporating a microprocessor. When operating in the dual mode, when the quantity of chemical foamant that must be added to the water stream to maintain a desired percentage mixture exceeds the capacity of the electric motor driven foam pump, control is transferred, via the hydraulic valve driver, to allow a hydraulic motor to drive a separate foam pump.

  • Patent number: 5492247
    Abstract: An automatic soap dispenser having an infrared sensing device and associated circuitry to trigger a driver device into operation. The dynamic power of the device is generated from a motor, through a speed reducing gear to deliver a low speed, high torque driving power to a toothed piece. The toothed piece is driven forward in a direction perpendicular to the soap feeding tube of the soap storage bag, allowing liquid soap in the feeding tube to be squeezed and dispensed for hands cleaning. When the squeezing operation is accomplished, the resiliency of the feeding tube pushes the toothed piece back to its original position and is ready for the next soap dispensing.

  • Patent number: 5464120
    Abstract: A frozen dessert dispensing apparatus is provided with a metering chamber having a predetermined volume into which a frozen dessert product is issued at a uniform constant rate from a bulk source. The time period required to fill the chamber volume determines a characteristic viscosity value of the dessert product which is advantageously used to time the flow of additional frozen dessert product from the source into and through the chamber to a selected point. The total time required to dispense a desired volume is based upon the viscosity measurement. A reciprocating piston arrangement provides gating of the frozen dessert product from the bulk source when in a first position and further acts to extrude frozen dessert product from the metering chamber when set in motion under the command of a controller. The piston arrangement includes a compressible plunger portion which deforms as necessary to prevent accidents or other mishaps from occurring in pinch-off regions of the apparatus.

  • Patent number: 5423455
    Abstract: An improved system and method for gravimetrically feeding material at a controlled rate. The material to be fed, which can be either a dry solid or a liquid, is maintained in a supply vessel. A probe disposed in the supply vessel detects the level of the material, sending a high level signal to a controller. A scale weighs the material in the supply vessel, sending a weight signal to the controller. The controller then calculates the density of the material in the supply vessel based on the weight and density of the material. The calculated density is used to affect the feed rate to achieve an operator-input set rate. During refill of the supply vessel, the probe detects material at a high level, sending a signal to the controller which, in turn, sends a signal to a refill valve, stopping refill.
