  • Cathode structure for cathode ray tubes and method for producing same
    Patent number: 4404492
    Abstract: Cathode structures for cathode ray tubes are multi-layer structures wherein the bond between the emissive coating and the substrate is improved by forming the coating from a laminate of at least two self-supporting layers of differing compositions, the bottom layer optimized for bonding to the substrate and the top layer optimized for emissive properties.
    Type: Grant
    Filed: August 24, 1981
    Date of Patent: September 13, 1983
    Assignee: North American Philips Consumer Electronics Corp.
    Inventor: George Palty
  • Cathode structure for cathode ray tubes and method
    Patent number: 4400647
    Abstract: Cathode structures for cathode ray tubes are multilayer structures wherein the multilayer structures are formed from a laminate of at least two self-supporting layers of particles of emissive material dispersed in a fugitive organic binder matrix.

  • Attaching self-supporting emissive film to cathode support
    Patent number: 4197153
    Abstract: In one aspect of the invention a process for affixing a self-supporting film of emissive materials in a binder to a cathode support member to provide a cathode for a cathode ray tube includes the steps of depositing at least one drop of a liquid mixture containing a solvent for the binder of the film onto a cathode support member, contacting the liquid mixture with the self-supporting film, and preferentially evaporating the liquid mixture to cause the binder of the film to affix the film to the cathode support member.In another aspect of the invention, an improved liquid mixture for affixing a self-supporting film of emissive materials in a binder to a cathode support member includes at least two liquids miscible in all proportions with one liquid essentially a non-solvent and another higher boiling liquid a solvent for the binder of the film.
    Type: Grant
