  • Patent number: 9610747
    Abstract: A variable compression screw press includes a volume displacing member which overlies the pressure housing feed flight of the screw press. In one embodiment, the volume displacing member is a shroud which may be moved in and out of the intake hopper as desired, without having to disassemble the press. In a second embodiment, the volume displacing member is a hinged gate which can be adjusted to overlie more or less of the pressure housing feed flight. In a third embodiment which may be used in cooperation with either first or second embodiment, the volume within the pressure housing feed flight is partly occupied by block elements removably mounted to the screw flighting of the pressure housing feed flight.

  • Patent number: 8936176
    Abstract: The present invention is directed to dispensers of bedding materials for laboratory animal cages. According to one embodiment of a dispensing unit, materials are drawn into a storage chute by a vacuum and dispensing is accomplished in a dispenser comprising a plurality of dispensing chutes having dispensing openings through which material is dispensed into cages. While in a first position, a material directing gate allows the materials to be dispensed through one of the dispensing chutes into a first number of cages, and through another one of the dispensing chutes into a second number of cages while in a second position. According to another embodiment of the present invention, the vacuum from the vacuum blower is utilized to remove dust from the dispensing area where material is dispensed into cages. Another aspect of the present invention is directed to a system for aligning, indexing and drying laboratory animal cages which have already been cleaned in a cleaning station.

  • Patent number: 4223813
    Abstract: Valving configurations between the valve seat in a cassette and the valve members in a controller used to limit the flow rate of an intravenous solution to a patient. The configurations minimize the criticality of the alignment between the components. The cassette forms part of the flow path of the solution on its way to the recipient. The controller's valve member may stretch a membrane in the cassette and cause it to contact a flat surface surrounding the opening through which the fluid must flow. Alternately, the end of the valve member may be appreciably smaller than the opening, pass through it, and stretch the membrane until the latter contacts all of the opening's edge. The membrane meeting the edge of the opening in a closed loop prevents the flow of fluid through it. As a further possibility, the valve member may place the membrane in contact with one or more edges provided between two segments of a straight channel through which the solution flows.
