Abstract: The present application discloses a liquid mixing method and apparatus which can mix two or more liquids in selected proportions. Each constituent fluid is introduced in a chamber provided with liquid level controlling devices that establish a liquid free head space which is connected to a source of pressure gas operative to pump or displace liquid from the chamber through a metering device prior to the introduction to a chamber where the constituent fluids combine.

Abstract: A constant level of liquid carbonation is achieved irrespective of the rate at which liquid is supplied to a carbonating vessel by, respectively, establishing a thin film of liquid over refrigerated heat transfer surfaces, which may take the form of plates, and controlling, in response to the flow-rate of the liquid, the area of the heat transfer surface covered by the liquid film.

Abstract: Apparatus for filling beverage tanks comprising a liquid manifold and a gas manifold for counter-pressurizing the liquid as it fills the tank. Supply conduits connect the tank with the manifolds. The gas supply conduit contains a coupling device for connection to a fill-height tube on the container. This coupling device includes an optical sensor embodying a prism which reflects light from a light source when the tank has liquid below a predetermined level and directs light onto a photo-conductor. When the liquid reaches a predetermined upper level in the tank and is forced into the coupling device through the fill-height tube, the prism changes its reflective characteristics, and light passes through the prism without reflection. The change in reflective conditions is brought about by the liquid covering adjacent sides of the prism. The photo-conductor correspondingly changes an electrical signal that is utilized to operate a solenoid valve for shutting off the liquid to the tank.

Abstract: A gas exchange deoxygenating unit is disclosed. The unit comprises a hollow mixing chamber having an upstream water inlet. A gas inlet located downstream of the water inlet delivers carbon dioxide gas to the mixing chamber. Stainless steel wool material within the chamber encourages turbulent water and gas flow and intimate water and gas intermixing. The mixed water and gas flows from the mixing chamber to a deoxygenating chamber containing a number of foraminous members mounted at spaced apart locations. Excess carbon dioxide gas and replaced oxygen is drawn from the deoxygenating chamber at a slight negative pressure. Below the deoxygenating chamber is a water collecting tank, which mounts controls for adjusting the level of water in the tank and flow rate of water through the apparatus.

Abstract: The embodiment of the invention disclosed herein is directed to apparatus for mixing various kinds and quantities of fluids to produce an admixture of beverages which is to be delivered to a filling station wherein the beverage is used to fill a plurality of receptacles, such as bottles and cans. The various stations of the apparatus include flow control valve means which allow the appropriate flow of fluid for producing the admixture of beverage during one instance and which closes off the flow of such fluids of the syrup and admixture for allowing the flow of a cleaning flud through the apparatus during another instance, this flow of cleaning fluid taking place without the need of disconnection of various fluid flow conduits or the like. Heating means, integrated in the system, elevates the temperature of the cleaning fluid sufficient to provide a sterilizing effect within the system.
