Abstract: A CRT implosion protection system having a resin system releasably bonding an implosion panel to the faceplate of a flat or concave CRT and a tension band system secured around the periphery of the faceplate which exerts compression thereon. The tension band system includes a pair of keeper bars which prevent the tension band from slipping, and which secure an external magnetic shield to the CRT.

Abstract: A resin bonding system which bonds a substantially flat implosion protection panel to the nominally flat faceplate of a flat tension mask CRT tube and is cured by exposure to ultraviolet radiation. The resin bonding system is designed for differential adhesion so that the faceplate separates more easily from the resin than does the implosion protection panel, thus achieving superior implosion performance. It also incorporates a contrast-enhancing neutral density agent, preferably confined to a flat layer adjacent to and adhered to the flat surface of the implosion panel in order to achieve uniform neutral density filtration across the face of the tube. The neutral density agent is preferably an organic dye.

Abstract: Components-in process and assemblies-in-process are disclosed for use in the manufacture of a high-resolution color cathode ray tube having a tensed foil shadow mask. A first component-in-process comprises a faceplate with a target area for receiving at least one pattern of phosphor deposits. The faceplate has attached at preselected, widely spaced locations on the sides thereof a plurality of discrete, detachable first indexing elements. A second component-in-process comprises a shadow mask support assembly having a frame ultimately constituting a part of the tube envelope; the frame supports the shadow mask in precise adjacency to the target area. The frame has attached on the sides thereof a like plurality of discrete, detachable second indexing elements which are in facing adjacency to the first indexing elements on the faceplate when the faceplate and frame are mated. Temporary attachment of the indexing elements is by means of a thermally degradable cement.

Abstract: In-process articles of manufacture are disclosed for the manufacture of a high-resolution color cathode ray tube having a tensed foil shadow mask. A first article-in-process comprises a faceplate with a target area for receiving at least one pattern of phosphor deposits.

Abstract: An image projection system using a projection type cathode ray tube and lens element. The improvement being a direct optical coupling between the display surface and the lens element comprised of a transparent, compressible, multi-layer, resin formulated pad wherein the outer layer of the pad are peelable.
