  • Patent number: 4932044
    Abstract: A system is disclosed for counting particles/cells within a counting box of precisely known volume that is completely inside a transparent section or sample. The box has a chosen height with defined upper and lower limits and appropriately selected width and depth dimensions. It resides completely within the sample and has no surface in common with an exterior surface of the sample. The system includes a compound light microscope that has a depth of focus which is small in relation to the thickness dimension of the counting box. The microscope includes adjustment means for moving the focal plane through a range which is greater than the height of the counting box. Display means are provided which show the portion of the sample that is within the depth of focus and user-operated means is provided to enable the user to mark the cells so displayed.

    Inventors: Robert W. Williams, Pasko Rakic
  • Patent number: 4654826
    Abstract: Each cell of a static latch implemented in MOS transistor circuitry includes an MOS transistor configured to operate a depletion mode and operably coupled to communicate an output node of the cell to an input node of the cell in absence of a control signal, to effect the latching operation. Presence of the control signal allows data to be efficiently written to the cell by enabling a transfer gate to establish a communication path for the data to the input node of the cell, while at the same time disabling the MOS transistor to terminate communication of the output node of the cell to its input node during the write operation.

    Inventors: Roy K. Yamanouchi, Robert W. Williams
  • Patent number: 4383823
    Abstract: This invention provides an oven to produce a desired baking effect while simultaneously providing the bread with a desirable brown coloration in both its top and bottom surfaces. A unique feature of this oven is the provision of a top radiant refractory arch wall and top flame heating to effect a desired radiance to the refractory arch surface, and also to simultaneously produce a desired radiance to a horizontally disposed radiant plate suitably disposed above the bread travelling continuously there beneath. The oven of this invention provides for substantially flash baking of relatively thin bread discs with a suitable crust formation and coloration of both its top and bottom surfaces. This oven provides also a novel method of baking relatively thin bread material.

    Inventors: Robert W. Williams, Vincent Montaruli
  • Patent number: 4197784
    Abstract: A revolver includes a mechanism for automatically cocking the hammer and indexing the cylinder after each shot by utilizing gas pressure generated after cartridge ignition. The barrel includes a gas cylinder open at the rearward end and extending forwardly of the frame. The frame includes a longitudinally extending bore aligned with the gas cylinder. A displaceable member is fitted within the gas cylinder and the frame bore and is biased to a forward position by a biasing member such as a spring. An opening in the barrel provides communication between the bore of the barrel and the gas cylinder so that increased gas pressure caused by cartridge ignition acts on the displaceable member to move it rearwardly. The displaceable member contacts the hammer to urge the hammer to a cocked position and also index the cylinder, thus readying the revolver automatically for the next shot.
