  • Patent number: 11118580
    Abstract: An absolute proportioning pumping system includes an electric motor assembly powering a first pump at a first flow rate and powering a second pump at a second flow rate. A proportioned fluid output includes a first fluid pumped by the first pump and a second fluid pumped by the second pump. The pumping system provides a desired ratio of the first fluid to the second fluid at the proportioned fluid output, relatively independently of pressure and flow rate at the output. In accord with further embodiments, a pump and motor assembly is mounted to and generally surrounded by a liquid tank. The pump and motor assembly may include a pair of fixed ratio outputs driven from a common motor, or may include a single variable output pump either slaved to a master pump or controlled through a timed bypass valve to control output flow rate.

  • Patent number: 8365991
    Abstract: A method and apparatus for vending a containerized fluid includes placing a machine-readable indicia on the container identifying the base fluid. The container may be filled and then distributed or distributed prior to filling through various distribution channels to consumers. When a consumer wishes to fill or re-fill the container, the consumer places the container adjacent a reader that interprets the indicia to identify the base fluid to be dispensed. A dispenser then fills the container through a movable fill probe that elevates as the liquid within the container rises. In some embodiments, and prior to filling, the dispenser apparatus may also query the consumer about options are provided at the time of dispensing for further dispensing various optional ingredients, including scents, flavors, colors, nutritional supplements or other additives together with the base product.

  • Publication number: 20120326585
    Abstract: A cabinet with sliding drawers has a mechanism for applying motive force in a first direction. The motive force is obtained from motion of the mechanism in an opposite second direction. The mechanism includes a cam and a cam follower. The cam includes a first part, a second part and an inflection point between the first part and the second part. The cam follower engages with the cam. The cam follower is configured to store mechanical energy responsive to translation of the follower and cam relative to each other in the second direction along the first part. The cam follower is also configured to apply motive force in the first direction to urge the follower to continue translation in the second direction along the second part. The motive force is applied after the follower passes the inflection point.

  • Patent number: 7922029
    Abstract: A cylindrical receptacle has an open space accessible from above, and an optional cover. An outer shell, an inner liner, and a pair of oppositely moving doors that slide about the circumference define the receptacle. The vertically extending side wall has an opening circumscribing substantially one half of the circumference formed in the side wall. The pair of doors are operative in a first position to fully enclose the opening and are operative in a second position to provide full access to the opening. Various alternative embodiments incorporate vertical reinforcing supports adjacent the opening, gussets circumscribing the opening for reinforcing the opening, a reinforcing spacer adjacent the receptacle top, a discontinuous spacer adjacent the receptacle bottom, a floor adjacent the base and sloped towards the opening, a feature locking the outer shell and inner liner together, and a taper so the receptacle may be stacked together with like receptacles.

  • Patent number: 7726921
    Abstract: A stanchion containment systems and method for securely storing and for safely accessing large and/or heavy items. The present stanchion containment system is particularly suited for use in dynamic locations. The stanchion assemblies includes a ceiling assembly releasably engaged with holes in the ceiling plate, and a deck assembly releasably engaged with holes in the deck plate. At least one linkage assembly connects the two or more of the stanchion assemblies. The linkage assembly substantially supports the stanchion assembly for translation from a first location to a second location, to provide access to the items.

  • Patent number: 6095372
    Abstract: A beverage dispenser, usable in dispensing milk, has a large refrigerated cabinet for housing large beverage containers. The beverage dispenser has a handle/valve with a first closed position, a second open position, and a third position for insertion and removal of a flexible milk tube. The handle includes two arms, and the user holds a cup between the two arms to receive the dispensed milk. The valve includes a cooling plate which refrigerates the milk in the flexible milk tube extending through the valve. The valve has a pinch plate which closes the flexible tube with a rocking motion, initially pinching the flexible tube at its lowest point and subsequently reopening the tube slightly to suck any beverage drops on the end of the tube back up into the tube. A hinged shelf is provided for ease of loading and unloading milk cases in and out of the refrigerated cabinet. The milk case has angled hand hold openings to allow lifting without repositioning of the wrists.
