Abstract: A method and apparatus for dispensing large numbers of wine servings at uniform temperatures is disclosed which includes a source (14) of wine at room temperature connected to a refrigeration unit (16). A wine dispensing valve (18) is connected to the refrigeration unit (16) for dispensing wine. A wine metering and mixing valve (A) is connected between a delivery line (20) and a dispensing line (22) to bypass a metered amount of room temperature wine from the delivery line to the dispensing line and thus raise the temperature of the wine to a desired wine serving temperature prior to serving.

Abstract: A carbonator valve assembly (A) is disclosed which includes a water valve entrance subassembly (B), a gas regulator valve entrance subassembly (C), and a vent valve subassembly (D) formed in a valve head (12) sealingly fitted in a neck of a carbonator tank (10). Gas entrance regulator valve subassembly (C) includes a pressure regulator-delivery valve means (E) which delivers a restricted flow of pressurized gas to a gas dispensing chamber (80) via a passage (100) and restricted outlet port (102). An unrestricted path for the pressurized gas is established through the carbonator valve assembly (A) via a control valve chamber (56) passage (64), chamber (62), passage (70), chamber (72), passage (78), and dispensing chamber (80). Dispensing chamber (80) includes valve seat (84) through which both the restricted and unrestricted gas flows enter the carbonator tank.

Abstract: An apparatus for charging a refrigeration system with a predetermined amount of refrigerant by weight. The apparatus includes a cylinder which is mounted on top of a strain gauge scale that is first filled from a source of refrigrant and then automatically discharged to fill a refrigeration system with a predetermined amount of refrigerant. The system includes solenoid operated valves which are automatically operated for loading the cylinder and charging the refrigeration system. A vacuum pump is also included in the circuit for placing the refrigeration system under a predetermined vacuum prior to the charging operation.

Abstract: A refrigeration system for cooling a beverage as the beverage is drawn from a container filled with water which has an evaporator coil carried adjacent the wall thereof which extends from adjacent the top of the container to the bottom of the container. When a refrigerant is circulated through the evaporator coil, an ice bank is built up on the inner wall of the container. A beverage dispensing coil is centrally located with the container and is connected between a faucet and the container from which the beverage is to be drawn. A helical support coil extends from adjacent the top of the container to the bottom and encircles the beverage dispensing coil. A temperature sensor is threaded inside the helical copper support coil so that any time the ice bank builds up closely adjacent thereto, it will turn off the compressor. A motor driven power paddle is used for circulating the water within the container.

Abstract: A refrigeration system for cooling beverages as they are drawn from a plurality of containers and dispensed through a plurality of faucets. A pair of beverage dispensing coils are centrally carried in a housing which is filled with water. A refrigeration coil encircles the housing causing a build up of ice to take place on the inner wall of the housing. A temperature sensor is carried within a helical coil provided between the beverage dispensing coil and the ice bank for operating a compressor associated with the refrigeration coil. A power-driven paddle is centrally carried within the container for circulating the water therein and a gentle, wiping motion. In order to selectively turn on and off the power paddle, a second temperature sensor is located in a junction provided between the inputs of the beverage dispensing coils.
