Abstract: A hot beverage dispensing machine is disclosed for dispensing a beverage from a concentrate. The dispensing machine includes a beverage concentrate container disposed in an inverted orientation within a refrigerated compartment. A first valve is associated with the container, the first valve permitting the flow of the concentrate from the container when the container is located within the refrigerated compartment in an inverted position. A receptacle having a receptacle output removably receives the inverted container. A first electrically controlled valve regulates the flow of the concentrate via the receptacle output to a mixer wherein the concentrate is mixed with hot water from a hot water tank. A second electrically controlled valve regulates the flow of hot water from the water tank to the mixer. A dispenser spout is disposed in fluid communication with the mixer with the spout being disposed remote from the hot water inlet.

Abstract: A liquid mixing and aeration system is disclosed comprising a novel liquid pump, a electronic circuit for controlling the system, and improved mixing for mixing flowing liquids. The system enables mixing of a first and a second liquids regulating fthe flow of the first liquid. A liquid pump is connected for pumping the second liquid. A control circuit controls the pump in accordance with the flow of the first liquid to maintain a given volumetric relationship between the first liquid and the second liquid. A mixer mixes the first and second liquid in accordance with the aforementioned volumetric relationship.
