  • Film-sheet assemblage for peel-apart self-developing film
    Patent number: 5356762
    Abstract: An improved film format for a self-developing, peel-apart film unit having flexible positive and negative sheet elements and a pod of developer liquid, wherein at least one of the sheet elements bends when a force is applied to a trailing edge thereof to effect sheet element movement. Pockets are formed on the leading end of each sheet element so that a force may be readily coupled thereto without bending either sheet element while they are being moved, for example, into a developer liquid spread system for subsequent film processing.
    Type: Grant
    Filed: November 24, 1993
    Date of Patent: October 18, 1994
    Assignee: Polaroid Corporation
    Inventors: Leonard Polizzotto, Robert J. Boyea

  • Structure and fabrication of components for connecting optical fibers
    Patent number: 4925267
    Abstract: The structure of a miniature component for use in connecting optical fibers along with methods for fabricating the component. A small scale tube having precision surfaces inside and out has formed directly in it a converging, preferably plastic, lens capable of imaging a fiber end properly located into assimilarly situated fiber in another like facing component. The outside precision surfaces of the tube serve as references for precision alignment of the component while its inside precision surfaces aid in formation of the lens.
