Abstract: A plurality of different liquid flavoring agents is accommodated at static pressure in respective compartments having bottom dispensing valves, and the interior bottom region of each compartment is placed in communication with the atmosphere above the top of the compartment. A quantity of carbonated water is discharged into an open receptacle at a location spaced from the compartment, so that it travels at atmospheric pressure towards the valves associated with the respective compartments. When the discharged quantity of carbonated water reaches the valve associated with the compartment containing the selected liquid flavoring agent, the valve of the compartment in question opens and discharges a preselected amount of the liquid flavoring agent into the carbonated water with which the flavoring agent becomes mixed to form a finished beverage that can be dispensed.

Abstract: A high-viscosity liquid is accommodated in a container whose outlet directly communicates with the intake port of a pump. The intake port communicates via a pump chamber with an outlet port of the pump, and an impeller having flexible blades rotates eccentrically in the chamber so that the blades wipe the surface of the wall bounding the chamber and pump liquid through the outlet port into a mixing chamber through which a water nozzle directs a stream of water which traverses the chamber and becomes mixed with the liquid to issue from an outlet of the mixing chamber as a completed beverage.

Abstract: An apparatus and a process for carbonating liquids, has inlet pipes for admitting a carbonating gas and a liquid into a container and outlet pipes for dispensing the carbonated mixture from the container. Cooling coils are provided in the container for forming an interior and an exterior surrounding ice layer so that the mixture can come into thermal contact with at least the interior ice layer and be cooled thereby. Electrodes are provided for preventing the thickness of at least the interior ice layer from exceeding a predetermined value.
