Abstract: A liquid metering dispenser is actuated by a trigger. The trigger releases a valve rod which is spring actuated to close a fluid pressure inlet, opening the discharge outlet of the dispenser to release a stored measured charge of liquid by operation of a spring actuated piston. The trigger is cocked by drawing the valve rod to close the discharge valve and open the liquid pressure inlet; the liquid under pressure enters the storage chamber, compressing the piston spring until it strikes an adjustable stop. The piston and spring assembly is readily removable for cleaning and servicing.

Abstract: A dispensing device for gasoline or the like liquid fuel which is mounted on a base structure or island as a part of the device, which occupies a relatively narrow space and may be of a hollow body so as to accomodate at least one of a flow meter, a fuel pump, and a motor for driving the pump. The device has at least three indication surfaces each directed in different direction around the device, so that an amount of the fuel dispensed and indicated on said surfaces can be read from any position around the device.

Abstract: A remote control fluid dispensing system is disclosed comprising a fluid dispenser and electrical pump means for pumping fluid from the dispenser at a dispensing station. Pulse generating means are provided at the dispensing station for generating DC pulses in metered response to the dispensing of fluid. Electrical to light energy transducer means and light to electrical energy transducer means electrically insulated from but optically coupled with the electrical to energy transducer means are provided at a control station. Electrical circuit means are further provided for coupling the pulse generating means with the electrical to light energy transducer means and for coupling the electrical pump means with a source of current at the control station. Display means are further provided at the control station coupled with the light to electrical energy transducer means for displaying metered dispensing of fluid information generated by the pulse generating means.

Abstract: A liquid fuel dispensing system having a plurality of dispensing pumps each generating electric pulses according to the volume of fuel dispensed and a central control where payment is made. A data transmission link couples each pump to the central control and each pump has a pulse store which accumulates pulses generated by the pump during a dispensing operation. A multiplexing unit at the central control samples the outputs from the pulse stores which are updated at each sampling.

Abstract: A batch controller for automatically and selectively controlling a plurality of material dispensers. The controller includes circuitry for metering, for slowing, and for terminating the flow of material in and at selectable quantity levels thereof. The apparatus includes a starting circuit that renders the apparatus inoperative in response to the absence or interruption of operating potential, and flow of the material is controlled by devices that provide fail-safe termination of flow in the event of failure.

Abstract: Draft beer monitoring apparatus in which the amount of beer dispensed is indicated in terms of the sales price, the indicator being controlled by a pair of pulsers operating at different rates associated with the dispensing of a glass or a pitcher of beer. The glass-rate pulser is actuated upon the operation of a switch when the dispensing tap is initially opened. If the tap remains open for a period of time greater than that required to fill a glass, a timer automatically actuates the pitcher-rate pulser instead of the glass-rate pulser.

Abstract: The present invention concerns an installation for the delivery of liquids including a main control station, tanks, pumps, pipes, valves, etc., and fed from the latter, at least one delivery "pump" having flow-meter, hose, delivery-nozzle, display panel for showing volumes and prices and apparatus for recording, computing and displaying the quantities of liquids delivered and the amounts to be paid.

Abstract: A double pump device for mixing with variable ratios and concentrations two or more liquids, comprising in combination: a first peristaltic pump, and a second peristaltic pump, each of said pumps acting on a plurality of collapsible tubes, said pumps being operated by two electric motors, interdependant and preferably identical to each other, driven by an electronic circuit comprising as main elements a differential amplifier and circuitry means for adjusting the input voltage of the differential amplifier and for amplifying the output signals from the differential amplifier before their application to the two driving motors.
