Abstract: A double sided primed circuit board is shown wherein one side is etched for receiving a plurality of surface mounted components constituting a control circuit. In one embodiment the control circuit provides for regulating the operation of a plurality to the beverage dispensing valves. An op-amp monitors the conductor for sensing the operation of the beverage dispensing valves as a function of a voltage drop there across. The conductor operates as a resistor, and any heating thereof that occurs as a result of the operation of the beverage dispensing valves is dissipated over the entire surface area of the circuit board. The control circuit also operates a dump valve for periodically dumping beverage if any of the valves have not been operated for a set period of time. The control circuit deactivates the operation of the dump valve during any sensed operation of one of the beverage dispense valves.

Abstract: A bi-directional ratchet conveyor is shown including a carrier bar slideably mounted centrally of a frame and operated by a power cylinder. The carrier bar has a first plurality of gravity dogs pivotally secured along a first side thereof, and a second plurality of gravity dogs secured along a second side thereof oriented in an opposite direction from the first plurality of gravity dogs. Dog operating rods are slideably secured to each side of the carrier bar for independently operating the first and second plurality of dogs between active and neutral positions. Each dog operating rod is operated by a separate pneumatic cylinder. When the first plurality of dogs are maintained in an active position, the second plurality of dogs are maintained in a neutral position, thereby providing for movement of goods in one direction along the conveyor through repeated extension and retraction of the power cylinder.

A coolant line extends through the python for cooling the beverages. A pump provides for pumping of a coolant through the coolant line from a refrigerated source thereof, through the python and back to the refrigerated source. A temperature sensor senses the temperature of the circulating coolant for regulating the operation of the pump in accordance with the sensed temperature.

Abstract: A nozzle for a post-mix beverage dispensing valve is shown for optimizing flow at flow rates above 3.5 oz./sec. The nozzle includes a first diffuser plate followed by a central flow piece having a frusto-conical outer water flow surface and an interior syrup flow channel. Second and third diffuser plates follow the frusto-conical portion. The second and third diffuser plates have perimeter edges that contact the inner surface of a nozzle housing so that the carbonated water must flow through holes in the diffusers. In this manner the gradual reduction of pressure of the carbonated water to atmospheric can be controlled in part by increasing the surface area of the holes in each successive diffuser.

The sensor turns a condenser fan on and off in order to maintain the condenser temperature within pre-determined limits and also shuts down the refrigerant compressor in response to a predetermined maximum temperature.

Abstract: A control system for use with a drink dispenser comprises a mode switch for causing the control system to switch between operation in a program mode and a dispense mode. Volumetric parameter data is provided by a volumetric parameter generator and is representative of dispensed drink volume. A memory stores the volumetric parameter data. A controller is coupled to the mode switch, the memory and the volumetric parameter generator and causes the volumetric parameter data to be stored in the memory while the control system is operating in the program mode and causes drink volume to be dispensed as a function of the stored volumetric parameter data while the control system is operating in the dispense mode.

Abstract: A beverage cooling, carbonating and dispensing apparatus has a refrigerator cabinet having a cold air cooling chamber, a cold beverage reservoir and carbonator in the cooling chamber, an outlet from the reservoir to a dispensing valve, and a spring-like helically coiled thermally conductive precooler secured to a beverage inlet of the reservoir, the precooler is suspended in the cold air chamber and has a substantial restriction to flow of beverage therethrough so that the refilling flow into the reservoir is very slow and is cooled to about 40 degrees F. (4.4 degrees C.) before admittance into the reservoir, so the entire contents of the reservoir can be dispensed without warmup or loss of carbonation.

Abstract: A beverage dispenser has a housing, a dispenser head with an electrically conductive combination beverage receptacle actuator lever and dispensed beverage level probe, a control circuit connected to the probe and to a start switch actuatable by the probe and to a solenoid for a beverage valve, and a drip tray and receptacle support wherein the receptacle support is tilted rearward toward the probe to support a tilted receptacle against the probe and keep the lowest part of a tilted receptacle rim against the probe; an improved probe assembly has dielectric journal piece isolating the probe from a body of the dispensing head, and a heater element is provided for the probe and either continuously or intermittently heats the probe to keep it insect free and sanitary.

Abstract: An automatic beverage dispensing system includes a probe assembly for automatically shutting off dispensing when dispensed beverage reaches a predetermined level. Upon initial shut-off, a waiting period occurs during which the foam portion at top of the beverage is allowed to settle. At the end of the wait period, an additional top-off period is initiated during which beverage is again dispensed to top-off the beverage to the desired level.

Abstract: The present invention discloses a method and apparatus for maintaining cold carbonated water in a beverage dispensing device so that unacceptably warm water is not dispensed therefrom. A modified beverage dispensing apparatus is shown including a carbonated water supply, a cold plate, carbonated water supply line extending through the cold plate, and in fluid communication with a carbonated water plenum immediately adjacent and in fluid communication with a plurality of beverage dispensing valves.
