  • Patent number: 5400838
    Abstract: An automatic packaging machine is provided which has a chute for directing objects such as cooked french fries into the interior of a rotatable loading drum. The drum is rotated by a motor about a horizontal axis at a speed to cause the french fries to first be carried upwardly and then to fall through a predetermined path within the drum. A staging carousel is provided for carrying a supply of varying sized packaging containers such as cups. The carousel can be rotated to a dispensing position where a single selected size container will be dispensed to an index carousel. The index carousel will move the container to a position within the drum to intercept the falling french fries to fill the container. A detector is provided for sensing when the container has been filled. Once the container is filled it is moved via various transfer mechanisms to a deposit or storage area which can accommodate a plurality of containers and has a mechanism for clearing space to receive additional containers.

  • Patent number: 5400836
    Abstract: An apparatus for and a method of filling a flowable product into a succession of receptacles as they pass continuously along a predetermined path is defined by an elongated hollow containment member mounted above the predetermined path which is formed with an axially extending slot therein. A metering screw having a helical thread is mounted for rotation within the containment member and is biased into sealing engagement with the containment member on each side of the slot. A distribution chamber is formed within the containment member substantially around the screw member except that the sealing engagement and the slot whereby flowable products supplied to the distribution chamber when the screw is rotated is distributed through the slot between adjacent screw portions of the screw member and leaves the containment member in a succession of spaced moving streams.

  • Patent number: 5398733
    Abstract: A readily cleaned liquid transfer system is designed for use with an associated vessel or container, such as a barrel, having therein a liquid to be removed. The system comprises a recirculation loop, a transfer manifold, and a transfer hose for providing flow communication between the transfer manifold and the recirculation loop. The transfer manifold has an inlet port which is located at about the bottom of the barrel, and an outlet port. The recirculation loop which has water flowing therethrough which is used as a diluent, also includes an eductor pump. The eductor pump hydrodynamically drives or draws the liquid in the barrel, through the transfer manifold and the transfer hose, into the recirculation loop. The recirculation loop discharges a blended product to a product tank.

  • Patent number: 5399821
    Abstract: A push-button switch keytop includes a flexible resin film deformed in such a manner that the resin film bulges upwardly to form a curved portion that is filled with a molding resin while the resin film is being deformed. The molding resin is allowed to harden to form a keytop body, whereby the top side of the keytop body consisting of the molding resin is integrated with the resin film in a state in which the top side of the keytop body is covered by the resin film. The keytop is manufactured by clamping a resin film between upper and lower molds, charging a molten resin from a pin gate provided on the lower mold into a cavity provided in the lower mold, thereby deforming and urging the resin film upward by pressure and heat produced by the molten resin and causing the resin film to adhere to the inner surface of the upper mold, filling the cavities of the upper and lower molds with the molten resin and separating the upper and lower molds after the resin hardens.

  • Patent number: 5396936
    Abstract: An improved filling machine is used for filling like containers with a like measured amount of divided material. The filling machine includes a housing and a drive connected to the housing. A filling turret is mounted in the housing. The filling turret includes a filling tank with a rotatable floor connected to the drive. A plurality of measuring flasks is arranged in a circle in the rotatable floor. Each measuring flask includes an open ended measuring tube and a sleeve telescopically mounted on the tube. The measuring flasks receive divided material from the filling tank. A container support maintains the containers in a horizontal plane. A control selectively lowers and raises the sleeve relative to the respective tube as the containers move with the flasks to measure the amount of divided material to be delivered to the respective container and then deliver the measured divided material into the container.

  • Patent number: 5396934
    Abstract: A method and apparatus for injecting CO.sub.2 gas into a bottled liquid to carbonate or maintain carbonation in the liquid. A valved coupling having a conduit extending there through is screwably attached to a P.E.T. bottle substantially filled with liquid. The valve is depressed .while the bottle is squeezed to remove any excess air in the bottle. Regulated CO.sub.2 gas is then fed through a connector that is attached to the coupling to carbonate the liquid. Once carbonated, the connector is removed while the coupling remains in place to maintain carbonation.
