Patents by Inventor Lawrence V. Pfaender

Lawrence V. Pfaender has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4268296
    Abstract: The invention provides a method and apparatus for the manufacture of glass film having a thickness not in excess of 0.003 inches and accomplished by drawing the film through a narrow slot-like orifice. The walls of the orifice are defined by an electrically conductive, hot glass resistant metal and electrical currents are introduced into the metal walls of the orifice to effectively maintain the central portions of the orifice walls at a higher temperature than each of the two lateral end walls of the orifice, thereby producing a temperature differential in the drawn film on the order of 40.degree. F. between the edges of the film and the central portions of the film.
    Type: Grant
    Filed: December 3, 1979
    Date of Patent: May 19, 1981
    Assignee: Owens-Illinois, Inc.
    Inventor: Lawrence V. Pfaender
  • Patent number: 4038577
    Abstract: Methods of making complex glass panel structures having precision dimensions. Glass tubes, rods, plates or other large glass structures are redrawn individually or in groups to filamentary or capillary size tube or gas continuums which are assembled as a monolayer to form a gas discharge panel, for example. Complex glass structures having precision uniform cross-sectional dimensions are constructed. Various novel glass structures and/or conductor configurations and methods of assembling are disclosed.
    Type: Grant
    Filed: April 12, 1973
    Date of Patent: July 26, 1977
    Assignee: Owens-Illinois, Inc.
    Inventors: Wolfgang W. Bode, Glenn H. Dunlap, Anthony M. Kobylak, Raymond S. Richards, Lawrence V. Pfaender
  • Patent number: 3973815
    Abstract: There is disclosed the manufacture and operation of a gas discharge display/memory panel having a pair of opposed support members carrying conductor arrays with an inorganic dielectric coating on the conductor arrays, and an ionizable gas confined between the opposed dielectric surfaces of the substrate.
    Type: Grant
    Filed: June 12, 1974
    Date of Patent: August 10, 1976
    Assignee: Owens-Illinois, Inc.
    Inventors: Wolfgang W. Bode, James F. Nolan, Lawrence V. Pfaender, Theodore C. Baker, Richard G. Mathias
  • Patent number: 3973164
    Abstract: There is disclosed a gas discharge display/member panel comprising opposed dielectric charge storage members backed by conductor electrode members and having an ionizable gas confined within the space between the opposed dielectric members, the conductor members being specific standardized visual shapes so as to form upon gas discharge alpha-numeric and other selected forms and shapes.
