  • Method for laminating a safety panel to a CRT and the product thereof
    Patent number: 4656522
    Abstract: Method comprises positioning a transparent safety panel in close spaced-apart relationship with the viewing window of a CRT and producing a mechanically-strong, hydraulically-tight closure between the panel and window around the margins thereof. The cell formed thereby is filled with curable liquid resin with the window and panel in an essentially vertical orientation. After bubbles have cleared and inspection completed, the liquid resin filling the cell is cured to an optically-clear solid.

  • Method for combined baking-out and panel-sealing of a partially-assembled CRT
    Patent number: 4493668
    Abstract: A method for fabricating a CRT (cathode-ray tube) in which a partially-completed faceplate-panel assembly is baked-out and heat-sealed to a funnel during the same baking cycle. Jets of oxygen-containing gas are directed intermittently into the open neck of the funnel at least during the heating-up period of the heating cycle.
