  • Patent number: 9295954
    Abstract: Methods, apparatuses, and systems for dispensing an off-gassing liquid product mixed with a diluting product are provided. A liquid product or product solution is moved through a primed product line and towards a dispenser. The liquid product is combined with the diluting product to create a solution. The solution is dispensed. Prevention of displacement of the product line is accomplished by redirecting at least a portion of the unused liquid product in the product line to a displacement system operatively attached to the product line and including a secondary container. The stored product may be used with the next dispensement of solution, or emptied in a sanitary manner.

  • Publication number: 20120074166
    Abstract: Bottled water dispensers are disclosed that include a water bottle receptacle. The water bottle receptacle includes a first and second floating baffle (with a hole disposed in the center portion of the second floating baffle). A raised ring having a triangular cross-sectional shape is located at the bottom portion of the receptacle, which makes contact with the second floating baffle, when the second floating baffle is buoyantly forced upwards into the raised ring to close an aperture through which water is transferred from the water bottle into a cold tank of the water dispenser (during hot water sterilization procedures, when the water level in a cold tank of the dispenser exceeds a threshold level). The second floating baffle is effective to prevent the undesirable heating of water contained within the water bottle during such hot water sterilization procedures.

  • Patent number: 6012481
    Abstract: A constant level of fluid (8 or 106) in vessel (1 or 104) is maintained using a reservoir (5 or 102) and a tank (4 or 101). Float valves (9 or 107) which raise and lower with the level of fluid in the reservoir are used to selectively close off fluid passages (13 or 109) from the tank into the reservoir. Until the desired level of fluid is reached in the reservoir, the reservoir continuously provides fluid to the vessel. Once fluid flow into the reservoir is stopped, flow from the reservoir into the vessel also stops. The vessel can be positioned adjacent to or remote from the reservoir.

  • Patent number: 4284210
    Abstract: A static metering pump includes a pair of tanks, electrically operated inlet and outlet valves, liquid level sensors and controls which permit the alternate filling of a first of the tanks while permitting the discharging of liquid from a second of the tanks and then permitting the discharging of liquid from the first tank while filling the second tank.

The two tanks are adapted to dispense the same volume of liquid in normal operation. Where the total volume of dispensed liquid called for includes a fraction of the normal volume of the tanks, one of the tanks is provided with a fractional liquid level sensor which may be preset to fill this tank initially to the fractional volume and to commence the metering operation by the discharge of this tank.
