    Abstract: A frozen yoghurt or ice cream dispensing system is presented. This system costs a small fraction that of the state of the art dispensing system, yet it is more versatile and puts out a better product, than the state of the art systems. A pre-formed "hard" frozen single serving of the base confection and fresh flavoring additives are loaded into an extrusion cup. At the actuation of a hand crank, or a power drive switch, a rotating cutter/sweeper on a retractable shaft, penetrates the confection charge and chops, softens, and mixes it. After this cutter engages the bottom of said cup, a piston traverses the loading cup bore, and the charge is extruded through a multi-aperture orifice, at the bottom of the extrusion cup. Shearing and additional mixing occurs, during the interaction of the rotating cutter and the multi-aperture orifice. An automatic rinse cycle is also built into the device, to eliminate flavor mixing between various batches of confections, and to save labor.

  • Patent number: 4898474
    Abstract: A mixing device for liquids is described, wherein improved control of the mix is achieved by restructuring the components so that the character of the mix can be observed easily and corrections effected simultaneously. The disperser/mixer incorporates a moveable and rotatable support structure attached to a piston-in-cylinder arrangement. Hydraulic pressure, pneumatic pressure, or a combination thereof in the cylinder is controlled from a unit on the support structure, rather than the base, through a modified piston fixed to the support structure and containing a passageway for hydraulic fluid, rather than through the cylinder.

  • Patent number: 4889432
    Abstract: A dental mixer apparatus including an upright mixing chamber having an upper open end for receiving dental impression materials and a plunger member suspended coaxially upon an elongated rotary driven mixer shaft for vertical reciprocable movement between a lower operative position in which the plunger is received within the mixing chamber and an upper inoperative position above the mixing chamber. A rotary mixer head is driven by the mixer shaft below the mixing chamber for mixing the materials within the mixing chamber. A suction conduit is provided to suck air from the mixing chamber in order to minimize voids and bubbles within the mixed ingredients. The mixer shaft is supported by a support bracket which is pivotally mounted to permit the mixer shaft and plunger to swing away from their normal vertical position above the mixing chamber to provide more working space above the mixing chamber.

  • Patent number: 4824255
    Abstract: A drive apparatus useful in screw injection molding apparatus is disclosed. The apparatus is particularly useful when both axial and rotational movements are required because the invention discloses a construction that reduces the wear attributed to sealing gaskets of relatively large diameter which are subjected to rotational stresses and relatively high linear velocities. In the injection molding embodiment described in detail, the extruder screw is rigidly attached to a drive piston that has both axial and rotational movements. Concentric to that drive piston is a drive cylinder tha has only axial movement yet is connected to the drive piston such that the piston is able to rotate freely relative to the cylinder but may move axially only when the cylinder moves. Thus, the sealing gaskets of the drive cylinder are free of rotational stresses which extends the useful life of the sealing gaskets.

  • Patent number: 4732487
    Abstract: Impeller means (4 and 5) is provided in a container (2) for agitating fluid. The impeller means is movable to effect fluid flow. The impeller means includes an impeller (4) which is separate from a wall portion of the container to a point of which the impeller (4) is connected by supporting means (5). Movement of the impeller means relative to the wall portion is achieved by making the impeller means flexible. A vibrator (6) may be provided to cause movement of the impeller means. The characteristics of the components can be chosen so that when the vibrator is activated the impeller vibrates with a greater amplitude than the wall portion (3). This can be achieved by vibrating the wall portion at a frequency approximately equal to a resonant frequency of the impeller means.
