Abstract: An ice bank control for use in controlling the size of an ice bank in an ice water tank in a beverage dispenser utilizes an especially constructed probe having a sealed tubular member containing an electrolyte treated water well therein. An electrode extends into the water well and a ground is in contact with the water well so that the probe senses the existence of ice at a point within the tank while the tubular member insulates the electrode and ground from contact, electrical and physical, with the contents of the ice water tank.

Abstract: A cover assembly for a beverage dispensing valve is provided having an easily accessibly front opening covered by a front cover which can be either swung open or separated from the main housing. The cover assembly is interconnected by pintles and gudgeons with the pintles removable from the gudgeons through guideways.

Abstract: A plain water boost system for a carbonated beverage dispenser provides for a pressure boost of plain water to be dispensed without the need for a second pump. A pressure regulator protected by an isolation valve is actuated when plain water is dispensed to reduce the output pressure of the carbonator input pump to an appropriate level for dispensing pressure boosted plain water.

Abstract: A beverage dispenser provides uniformly chilled carbonated beverages during peak demand and off-peak demand. The dispenser includes a soda and syrup chiller, beverage dispensing heads and a vacuum insulated tower assembly between the chiller and the dispensing heads.

Abstract: An ice chest-type soft drink dispenser containing a body of ice in contact with a cold plate at the bottom thereof. The cold plate contains syrup and carbonated water tubes through which syrup and carbonated water passes, respectively. A pre-chill coil of a plurality of turns of tubing embedded in an aluminum body is provided, separate from the cold plate and the tubing is in fluid communication with the carbonated water tube and a source of carbonated water.

Abstract: A beverage dispenser provides uniformly chilled carbonated beverages during peak demand and off-peak demand. The dispenser includes a soda and syrup chiller, beverage dispensing heads and an insulated tower assembly between the chiller and the dispensing heads.

Abstract: Adjustable flow control valves are disclosed for controlling the flow of syrups and diluents at a corresponding predetermined constant flow rate regardless of the pressure of the fluid being controlled. The valves include a cylinder and piston assembly in which the piston has an inlet orifice and controls outlet ports from the cylinder to maintain a constant flow rate. Dual spring arrangements provide for adjusting the range of flow rates which the valve can accommodate in connection with varying pressure and varying viscosity of the liquid being controlled, and variable piston orifice arrangements are disclosed for the same purpose. An improved cylinder construction comprising sleeve and bonnet components is disclosed and provides for the outlet ports from the cylinder to be provided in the bonnet component.

Abstract: A relatively simple and compact beverage chilling device for providing uniform beverage temperatures in a post-mix beverage dispensing system regardless of the duration between usages. Chilled plain or carbonated water is circulated in an insulated conduit between a cooler and a dispensing tower with portions drawn off at selectively operated dispensing heads. Flavored syrups are supplied to the dispensing heads within the same insulated conduit. A thermal mass disposed in close proximity to the dispensing heads provides a heat transfer medium from the syrups to the chilled water.

Abstract: A control circuit for a beverage dispenser provides accurate uniform automatic cup filling. The circuit includes an initial latch feature which prevents premature shut-off of the dispenser valve and a mechanism for overcoming false cup-fill conditions to assure uniform filling.

Abstract: A beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed is provided with a solenoid actuated valve arrangement between the diluent and/or syrup supply line and the dispensing nozzle and which solenoid valve has a sealing arrangement which, upon actuation of the solenoid, provides sequential first and second stages of pressure drop across the valve seat, thus to reduce the power required to operate the solenoid and open the valve or enable the valve to operate under higher fluid pressures without increasing the power of the solenoid.

Abstract: In a carbonated beverage dispensing apparatus including a dispensing valve, carbon dioxide gas is introduced into a liquid to be dispensed through the dispensing valve, and a temperature sensor is arranged to sense the temperature of the liquid, either in a carbonation tank or in the path through which the liquid is fed to the carbonation tank. A control, responsive to the temperature sensor, controls a valve which regulates the pressure at which carbon dioxide is introduced into the liquid. The carbon dioxide pressure increases with increasing liquid temperature, so that the carbonation level in the liquid dispensed through the dispensing valve is maintained at a substantially constant level. Both mechanical and electronic controls are disclosed.
