Abstract: A cathode-ray tube with a platform adhered to the external surface of the tube by at least one mass of solidified thermoplastic adhesive and at least one mass of irreversibly-hardened adhesive. The method includes applying masses of liquid thermoplastic and liquid irreversibly-hardenable masses between the platform and the tube surface, and then solidifying each of the adhesive masses.

Abstract: A CRT comprising a screen support, a luminescent viewing screen on the support, a light-reflective metal layer on the screen, and a particulate layer of carbon particles and preformed silica particles on the metal layer. The particulate layer may be made by spraying a suspension of carbon (amorphous carbon and/or graphite) and silica (less than 0.1-micron size) on the metal layer while it is preheated in the 50 DEG to 75 DEG C. range.

Abstract: A cathode-ray tube comprising a glass viewing window having, on its external viewing surface, an antistatic, glare-reducing, image-transmitting coating. The coating has a rough surface and is composed essentially of a silicate material and a metallic compound in proportions to impart the desired antistatic characteristic without substantially degrading the image-transmitting capability of the coating. When the tube is operated, the coating is grounded either directly or through the metal implosion-prevention system on the tube.

Abstract: 1350501 Coated luminescent screens R C A CORPORATION 21 Oct 1971 [28 Dec 1970] 48933/71 Heading B2 [Also in Division H1] A method for providing a black carbon coating on a light reflective metal film covering a c.r.t. phosphor layer (e.g. mosaic of areas such as dots) comprises heating the phosphor layer and metal film to between 50‹C and 75‹C, depositing on the heated film a coating of an organic volatilizable film-forming material from an aqueous dispersion, and depositing upon the coated metal layer an overcoating of carbon particles deposited from a suspension substantially free of organic and inorganic binders. The structure reduces heat reflection to the shadow mask of a three beam colour TV c.r.t. for example. Reduction of electron scattering and secondary emission is also instanced. The organic film forming material may be an acrylic polymer, and the suspension may be amorphous carbon and graphite particles in an aqueous vehicle. There may be a further volatizible film between the metal film and the phosphor layer, and the structure may be heated to 400 to 450‹C in air to volatilize both films. The aqueous dispersion of the organic film-forming material and the carbon particle suspension are preferably deposited by spraying. The metal layer may be a 2500A Al film. In embodiments, the aqueous acrylic resin emulsion may contain, as well as solids, deionized water and red dye solution, amounts being specified, the latter facilitating later inspection. The resin emulsion may be principally ethyl acrylate, copolymerized with equal minor amounts of acrylic and methacrylic monomers and polymers. The carbon suspension may include, in specified amounts, aqueous suspension of colloidal graphite, deionized water, aqueous dispersion of carbon black, containing 0.5 wt. % dispersing agent such as sulfonated lignin and 0.1 wt. % wetting agent such as polyoxyethylene lauryl ether. Coating may be by automatic machinery. Another example includes a spray of acrylic resin solution, deionized water and Rhodemine dye powder and the barrier layer may also be an aqueous emulsion of polystyrene. The metal film has pores enabling escape of gases during baking. The carbon may be in toluene, xylene or dispersed in water, preferably with wetting and dispersing agents. Carbon and Al coatings are preferably 2000 to 3000A thick.
