Abstract: An air logic controller and metering pump unit is provided for an automatic liquid transfer and metering apparatus. Such apparatus is designed for bulk storage, handling and transportation of liquid chemicals and for the safe, precise and metered delivery and transfer of liquid chemicals from a source of chemical bulk storage to the place of end use. One form of apparatus includes a portable liquid transfer tank which is used in conjunction with a stationary wall mounted air logic controller and metering pump module located near the place of end use. Another form of apparatus is a portable self-contained unit where the air logic controller and metering pump module and a compressed air supply tank are mounted above and are connected to the portable liquid transfer tank module. Thus the self-contained unit having its own energy source may be moved to any plant location for precision dispensing of chemicals without the requirement for additional sources of air, electricity, hookups, etc.

Abstract: A self-service station where a number of parties, each having an individual operating key or card, can pump gas from a single pump by inserting the key or card into a matching slot to activate the pump. When the fuel begins to flow to the discharge nozzle, a pulsing device is activated to register on a counter the amount of fuel pumped. To prevent pumping of fuel under circumstances where the pulsing device is not operating, there is a timer that shuts off the pump if the pulsing device does not become operative after a certain period of time. The timer is arranged with a flow responsive switch so that the time period is measured from the time fuel actually begins to flow to the time that the pulsing device starts to operate. This permits the time period to be made relatively short to minimize the pumping of fuel without recording the same on the counter.

Abstract: A soup dispenser is provided which will dispense liquid, semi-liquid and/or chunky soups, stews, chilis, etc., with equal facility.

Abstract: An insulated air pot for hot water and the like has a hinged circular cap on the top of which there are arcuate indicators showing the volume and temperature of the liquid in the pot. The volume indicator comprises an indicator hand coupled with the upper end of a twisted strip which slides in a slot in a float member so that it is rotated as the float member rises or falls. The temperature indicator comprises a thermometer of arcuate shape having a bulb in the upper end of a heat conducting conduit. A ball valve at the top of a discharge pipe closes the pipe except when liquid is being discharged and thereby conserves heat.

Abstract: A processor is used to control a price display unit for a fluid-dispensing system. The amount of fluid dispensed by the system in measured and information responsive thereto is fed to the processor. The processor calculates the cost of the dispensed fluid and those costs are then displayed. The processor automatically cross-checks the validity of the displayed cost with the amount of fluid dispensed. A plurality of self-checking features insure proper system operation and also preserve signals stored in a memory if there is a power failure.

Abstract: A portable liquid metering device for detachably securing to the opening of a liquid container and adapted to discharge a predetermined volume of liquid upon tipping and having a register for counting and displaying the number of times the bottle is tipped.

Abstract: Drink dispensing apparatus is presented wherein a system including plural dispensing terminals communicates with a central source of beverage ingredients for dispensing. Each of the terminals is interconnected with a central microprocessor which communicates with each of the terminals and the source of beverage ingredients to dispense to the respective terminals the particular formulations selected thereat. Further presented is circuitry interfacing the microprocessor with the various terminals such that automatic pricing, inventory control, sales totalization, and other housekeeping techniques may be performed by the microprocessor on a terminal-by-terminal basis.

Abstract: An electronic analgesia/anesthesia apparatus is provided for the administration of a mixture of gases. This said apparatus has separate controls for independently increasing or decreasing the flow rate of each particular gas to be delivered thereby and includes an electrical circuit operatively connected to each control for driving a display indicative of the flow rate of the gas and a percentage calculator connected to each individual control for calculating the percentage of a particular gas with respect to the total gas flow and for displaying same; high and low pressure limit alarms and a pressure responsive safety control are included.

Abstract: An automatic control circuit is provided for diluting a chemical concentrate in a container by the proper proportion, dispensing the mixture, indicating that the container is empty, and repeating the process. The container has a plurality of conductive probes which extend to different depths within the container. A pair of relays having contacts which control drain and fill solenoid valves in the container are controlled by the probes, depending on the level of the liquid in the container. Both visual and audible alarms are provided to indicate when the tank is empty and needs concentrate to be added thereto.

Abstract: An apparatus for dispersing substances into one another by subjecting them to shear forces between a rotating platen and a stationary or counter-rotating platen which have opposed work surfaces interfaced and forced toward engagement with one another. An oriface leads through one platen to the other platen. A pump forces an agglomerate of substances through the channel and radially outwardly between the platens during relative rotation of the platens. The agglomerate is subjected to shear forces as it moves radially outwardly between the platens to disperse the substances to one another. The mutually dispersed substances emit at the periphery of the platens and are collected in a trough.
