  • Patent number: 6220589
    Abstract: A two-way dual action clamp for accurately clamping together two or more workpieces. The clamps are particularly useful in temporarily clamping together two European style wall cabinets prior to permanently joining the units together with a plurality of screws. Each clamp has two jaws, one L-shaped and one I-shaped which, when assembled form a U-shape. The jaws are manipulated by a hand operating screw so as to clamp together workpieces such as abutting sides of frameless cabinet units. A second hand operating screw carries a pressure plate and extends transversely through a threaded opening in the bight portion of the U-assembly. The pressure plate acts to bring edges of the cabinet units into flush relationship. The distal ends of the jaws are provided with spring actuated workpiece engaging and retaining cams which are spread apart to a limited extent when workpieces are inserted between them.

  • Patent number: 5923921
    Abstract: An apparatus for mechanically assisting the transfer of an image from an image bearing member onto a substrate. The apparatus includes a transfer assist blade that forces a substrate toward an image bearing member, a motor, a mechanical assembly for coupling the motor to the transfer assist blade such that motor operation changes the transfer assist blade force, and a controller that controls the motor operation. The controller might receive inputs from a substrate sensor, an operator control panel, and/or a service adjustment. The controller might use those inputs to control the motor operation, and thus the transfer force. Alternatively, the controller might control the transfer force as a result of the operation of the overall machine, such as by changing the transfer force during duplex printing or during the transfer of various color images.

  • Patent number: 5155849
    Abstract: The method of changing system files to be able to change either the primary or secondary language or both on a rigid disk to another language, and to provide the operator with the option of selecting either the primary or secondary language as the medium for the display messages and prompts by providing the language requirements on a floppy disk, identifying the specific files of the control to be altered to produce the language requirements, loading the floppy disk into a floppy disk drive, and transferring the language requirements to the rigid disk.

  • Patent number: 4425232
    Abstract: A flotation separation cell is disclosed having a rotor-stator pump assembly wherein a rotor body comprises integrally formed hub, blade and top plate members. These members form a gas chamber in an upper sector of the rotor. The blades are curvilinear and of parabolic or vortex shape. A gas stream which is conveyed to the gas chamber is discharged from the gas chamber in a transverse direction and flows in gas pockets along surfaces of moving blades for dispersion in a slurry.
