  • Apparatus for fabricating a color cathode ray tube
    Patent number: 4021819
    Abstract: The invention provides conjunctive apparatus for facilitating the fabrication of the basic pattern windowed-web portion of a color cathode ray tube screen structure formed in the viewing area of the face panel. In accordance with the invention, additional photo-exposure of the panel is discretely effected by the apparatus to polymerize a defined band of coating confined to the sidewall portion of the panel. The presence of this band subsequently facilitates expeditious removal of extraneous graphite coating from the panel sidewall, from the mask positioning studs embedded therein, and from the terminal sealing edge therearound. Thus, the apparatus of the invention provides desirably bare sidewall-associated surfaces that are free of deleterious particulate matter.
    Type: Grant

  • Radiant energy emitter for color CRT fabrication
    Patent number: 3955094
    Abstract: The invention provides radiant energy emission means utilized in an apparatus for discretely photo-exposing sensitized coatings disposed on the sidewall portion of a color cathode ray tube glass face panel. The emission means includes a source of radiant energy and an associated transparent energy transmission medium in the form of a cylindrical collector rod positioned in a manner whereof the output portion thereof extends within the panel. The cylindrical surface of the output portion within the panel is abraded to laterally emit exposure radiation radially outward toward the sidewall of the panel.
