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: The timer controls a dispensing machine and in particular controls the dispensing cycle for a product such as coffee, a beverage, or instant mashed potatoes. The control includes regulation of the water portion of the cycle and the solid or powder portion of the cycle. The timer is controlled by a plurality of touch switches each coupling via a resistor network to the control logic of the timer. The control logic is preferably CMOS-type having a high input impedance permitting use of a resistor network of high resistance to limit current flow especially under fault. The touch switches control functions such as "hot water", "large portion", "small portion", "stop", and "push and hold".

Abstract: A bidirectional semiconductor switch such as a Triac in the usual failure mode, wherein the device conducts continuously in only one direction, has a storage circuit in series intermediate the triac and load. The storage circuit may comprise a single capacitor preferably of predetermined value and adapted to, after a relatively short time-out period, interrupt power applied to the load. The capacitor is preferably a non-polar type, although, in an alternate embodiment a pair of oppositely-poled polar capacitors may be employed.

Abstract: The timer controls a dispensing machine and in particular controls the dispensing cycle for a product such as instant potatoes by temporally regulating the water portion of the cycle in conjunction with the solid or powder (potato granules or pearls) portion of the cycle. The water flow is usually controlled using a solenoid or the like while the quantity of potato is regulated by an auger and associated drive motor. The dispensing cycle is initiated by a pre-rinse period wherein only water flows. During the main part of the cycle both water and product flow into a mixing area. The cycle ends with a post rinse period that is either positive or negative; positive when the product flow stops first and negative when the water flow stops first. For multiple portions, rather than extending the length of the main part of the cycle, the timer provides for repeating the basic cycle a number of times that relates to the desired portion.

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.
