  • Patent number: 6817203
    Abstract: The invention relates to a device for the discontinuous production of ice-cream from a liquid mixture. Said device comprises a processing container, in which at least one tool is mounted so that it can rotate and repeatedly apply the liquid mixture to and scrape the latter from the refrigerated interior wall of the processing container, a fill opening for the liquid mixture and a discharge opening for dispensing the ice-cream from the processing container. The longitudinal axis (L-L) of the processing container (10) is inclined at a first acute angle (&agr;) in relation to the horizontal (H) and the rotating tool (20) comprises spatulas which are configured and mounted in such a way that they continuously transport the ice-cream mass which forms to the discharge opening (15), lying at the lowest point of the processing container (10).

  • Patent number: 6814029
    Abstract: A game feeder utilizes an improved feed dispensing mechanism that allows feed to enter the feed dispensing mechanism from the side. A game feeder utilizing the improved feed dispensing mechanism prevents access to the feed through the feed dispensing mechanism thereby eliminating the need to keep the game feeder out of the reach of wild animals.

  • Patent number: 6789935
    Abstract: The invention relates to a method for the vertical mixing of gaseous, liquid, powdery and/or pasty products using, for example, a hollow shaft and inner shaft arranged in a housing, whereby paddle-shaped mixing tools are provided on the hollow shaft and on the inner shaft there is provided a discharge device arranged below an outlet of the mixer. The mixer is thereby completely filled in the operating state and the product and additives are pressed onto the inner wall of the housing by means of the mixing tools. The product flows continuously downwards under the force of gravity and acts against the partly backward-conveying paddles. The continuous product flow is regulated using a rotary slide valve provided at the outlet. The mixer is especially suitable as a dosing device and/or for lubricating extruder and/or expander products.

  • Patent number: 6663276
    Abstract: An agitator assembly for agitating a substance in a container comprises a container, a magnetic drive device, and an agitator element. The magnetic drive device is disposed adjacent to an outside surface of a lateral wall of the container. The agitator element is disposed in the container and is magnetically coupled with the magnetic drive device for self-supported rotation about a central longitudinal axis. The agitator element includes an agitator body, a first magnet mounted at the agitator body, and a second magnet mounted at the agitator body and circumferentially spaced from the first magnet. The agitator element substantially centered about the central longitudinal axis and supported at a substantially constant axial position within the container by the magnetic drive device.

  • Patent number: 6592249
    Abstract: The invention relates to a device (10) for producing and/or processing plastic material mixtures comprising a mixing head (11) which has one or several inlets (15) for the mixture constituents and in which a mixer (17) provided for mixing the constituents is rotationally driven. An outlet (22) is provided in the mixing head for ejecting the finished mixture. Said outlet can be closed or opened by the head of the mixer in the manner of a nozzle needle. To this end, the mixer is arranged in the housing (12) of the device such that it can be axially displaced. In order to prevent an abrupt opening or closing of the outlet, which can thus lead to losses in quality when using sensitive plastic materials, the invention provides that the raising and lowering of the mixer in the mixing head is effected via a mechanical cam drive (40) comprising at least one actuating cam (42) which interacts with a lifting element (60) that acts upon the mixer (17) or the shaft thereof (24).

  • Publication number: 20030117889
    Abstract: A mix head assembly including a mix chamber having a mixer rotatably mounted therein. The mixer extends for a longitudinal length and defines a multiple of vanes which agitate the fluid material components as the mixer is rotated. A plunger is movably mounted in the mix chamber relative to the mixer. As the plunger is driven relative the mixer, the plunger scrapes the fluid material off the mixer such that no remnants remain within the mix chamber.
