Rotary Agitator Patents (Class 222/235)
  • Patent number: 5286106
    Abstract: A DC-motor-driven whisk blends soap remnants with water until creamy. The blending is done in a translucent housing over the motor where the shaft of the motor rotates the whisk. The soap cream is dispensed through a pump dispenser that extends into the housing. The whisk has two differently-shaped arms for more efficient blending and to avoid interfering with the pump dispenser. Water and soap are added through holes in the top of the housing that also enable soap fragrances to vent into the vicinity of the device.

  • Patent number: 5188262
    Abstract: Material dispensing apparatus includes an elongate hopper having a flexible apertured bottom, and an agitator bar mounted for rotation within the hopper having a plurality of circumferentially spaced longitudinally extending rods supported on a rotating stabilizer shaft for material dispensing contact with the apertured bottom. The contact between the longitudinally extending rods and the flexible apertured bottom moves the bottom of the hopper in both an up-and-down and side-to-side direction such that the holes in the bottom change shape and material contained within the hopper is both vibrated and pushed through the apertures in the bottom of the hopper onto a product underlying the hopper. The apparatus is designed to dispense moist pre-sized powder-like materials that tend to agglomerate and adhere together.

  • Patent number: 5071040
    Abstract: An apparatus for mixing and dispensing a surgical adhesive having at least two components has a barrel with a central longitudinal axis extending from a first to a second end thereof. The second end includes a nozzle with a discharge port. A rotatable screw conveyor shaft extends through the barrel position along the longitudinal axis. A dispensing element is mounted within the barrel and has a threaded bore for operative engagement with the screw shaft. The dispensing element has a keyway and may freely rotate at the first end of the barrel. A snap element is included to move the dispensing element into engagement with a key on the inner surface of the barrel which prevents the rotation of the dispensing element and causes the dispensing element to move from the first end of the barrel to the second end dispensing the adhesive.

  • Patent number: 4993593
    Abstract: A flowable medium, such as a liquid, a semi-liquid, or a liquid containing particulate matter, can be automatically dispensed in a premeasured amount or in a continuous stream. When the flowable medium is being dispensed in a premeasured amount, such amount is isolated from the remainder of the flowable medium during the dispensing operation so that it can be dispensed independently of any head pressure created by the remainder of the flowable medium. By using a temperature sensor in combination with a microcomputer system for the purpose of detecting large fluctuations in the temperature of the flowable medium, it is also possible to determine when the remainder of the flowable medium reaches a low level condition.
