Abstract: A non-carbonated beverage dispenser having an in-bowl whipper assembly which includes a housing disposed in the bowl and immersed in the beverage, a magnetically driven impeller in the housing, and a discharge passage from the housing connected to the spigot of the dispenser to discharge the whipped beverage from the bowl. The whipper is rotated at 4000 rpm or above, and the height of the impeller blades is made very small (in the order of 1/32 to 1/16 inch) to produce very fine and uniform bubbles in the beverage without uncoupling the magnetic drive.

Abstract: A refrigerated beverage dispenser particularly designed to handle perishable beverages such as milk wherein the bowl has an opening in the bottom wall through which a spout extends that is part of the outlet tube mounted in the bowl and submerged in the beverage. The outlet tube is made of a good heat conductive material such as brass and the refrigerated beverage in the bowl is circulated over the surface of tube to maintain the tube temperature at the temperature of the beverage. A valve is mounted in the outlet tube, and a port is provided in the outlet tube upstream of the valve through which beverage in the bowl may discharge through the spout. A push handle mounted outside the bowl is connected to a push rod that extends through a tubular support in the bowl, and the push rod is coupled to the valve.

Abstract: A coin-operated liquid dispensing machine having a vending control mechanism which may be conveniently altered to accept a different coin or series of coins to reflect different vending prices that are to be charged. In the disclosed arrangement vending prices of 5.cent., 10.cent., 15.cent., 20.cent., 25.cent. and 30.cent. are selectable. The control mechanism includes a timer motor for driving three cams each having electrical circuitry associated therewith including cam contact switches. The first cam is a stepping cam, the second an override cam and the third cam controls a dispensing gear motor. The electrical circuitry also includes 5.cent. and 10.cent. switches and associated relays, a relay by-pass switch, and manually operated blocking structure associated with each coin slot (5.cent. and 10.cent. slot).

Abstract: A dispenser for high density liquids such as barium sulphate comprising a housing with a bowl seated on the housing and containing the liquid. Refrigeration coils in the bowl chill the liquid, and a variable speed paddle type pump also in the bowl mixes and circulates the liquid about the refrigeration coils and maintains the mixture in suspension. A dispensing valve assembly includes a body having a passage which extends axially through it and a vent tube that extends upwardly from the body. The vent tube and body prevent build up of the liquid about the valve which otherwise would dry and cause valve blockage.
