  • Patent number: 4772884
    Abstract: An AC gas discharge display panel is described which employs the phenomenon of plasma spreading. In the panel, plasma spreading or "coupling" is employed to couple the plasma to an addressed cell to one of a plurality of pixels to be illuminated. The spreading is controlled by assuring that the cell wall voltages are properly related so that the plasma's electrons migrate to a region where the voltages are approximately equal to or more positive than the wall voltages where the plasma originated. Paired sustain electrodes are selectively energized to enable diversion of the coupled plasma to the desired pixel, so that upon subsequent applications of a sustain voltage, the desired pixel is illuminated (or erased) as the case may be.

  • Patent number: 4740283
    Abstract: A pulsed-field gradient gel electrophoretic apparatus is described wherein a free standing gel is employed. Electrode arrays are oriented to provide three dimensional fields across the face of the gel rather than in the plane of the gel. The electrodes produce three dimensional fields which are orthogonally oriented with respect to each other and cause the molecules to proceed down the lanes in the gel in a generally saw-tooth manner oscillating between the surfaces thereof. Alternately, three dimensional, electric fields are arranged at angles greater than 90.degree. to one another across the face of the gel in separating the molecules, following which transfer electrodes are substituted for the separation electrodes in order to transfer the molecules from their separation lanes onto a separate substrate.

  • Patent number: 4735194
    Abstract: A flexible endoscopic ligating instrument comprises a flexible fiberoptic endoscope on the end of which is secured an outer tube and an inner tube inserted and reciprocally movable within the outer tube. An elastic ring is mounted peripherally on the end of the inner tube which projects beyond the outer tube. A trip wire is fastened to the inner tube to provide rearward motion to the inner tube and thereby cause the elastic ring to slide off and effect ligation. The instrument is particularly suited for ligating lesions deep within the alimentary tract such as esophageal varices.

  • Patent number: 4677539
    Abstract: A dc to three phase ac switched mode converter is described wherein a six switch bridge is provided to interconnect the dc source to a three-phase load. A plurality of dc sources are described, each of which employs an inductor/capacitor combination for energy storage, which stored energy is subsequently applied to the output load. The stored energy is delivered by connecting the capacitor across two legs of the three-phase load, while assuring that the third leg is invariably short-circuited back upon itself. As a result, three of the six switches in the bridge are closed at any instant to prevent any current interruption in the load.
