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: 1360182 Glare reducing coatings R C A CORPORATION 3 Feb 1972 [8 Feb 1971] 5099/72 Heading B2E A method of producing a glare reducing coating on a surface from a formulation of a siliceous polymer, an organic polymer and a volatile organic liquid vehicle for said polymers, by (a) producing a spray of descrete droplets of said formulation in a gas, (b) intercepting at least a portion of said spray upon said surface to produce a layer of droplets thereon, (c) volatilising substantially all the vehicle in said layer of droplets, leaving a substantially dry textured polymeric layer on said surface, and (d) baking said dry layer at 100 to 200‹C. The method is particularly useful for coating glass, G.R.T. faceplates. The organic polymer is preferably polyvinyl butyral alone or mixed with partially hydrolised polyvinyl acetate and the siliceous polymer is preferably the hydrolysis product of heating tetraethyl orthosilicate with HCl solution at 50‹C for 1 hr. once the heat of reaction is being released, then cooling to room temperature. The organic polymer may be natural or synthetic. Examples of such polymers listed in U.S. Specification 2,404,426 include resins made from cumarone; indene; acetylene optionally halogenated; olefin hydrocarbons, such as ethylene, or butadiene, optionally halogenated; olefin/sulphur dioxide; petroleum and derivatives thereof made by reaction with formaldehyde, acetaldehyde, metallic halides, sulphur or sulphur chloride; styrene and derivatives thereof; phenol-aldehyde; aldehydes; furfural; ketones; urea-formaldehydes such as thioureaformaldehyde, melamine-formaldehyde and dicyandiamide-formaldehyde; amine-aldehydes; sulphonamide-aldehydes; nitro resins; resins made from hydrazine and derivatives thereof, pyrozoles, pyridine, quinoline, pyrrole, indole or carboazole; resins from wood and carbohydrates; natural resins and esters thereof such as rosin, shellac and ester gum; polyesters; mixed polyester-polyamide resins; polyether resins, polyvinyl ethers, alcohols and esters; polyvinyl acetals; polyacrylic acids, anhydrides, esters, amides and homologues thereof; rubber and derivatives thereof; olefin-sulphide resins; phenol-sulphur and phenol-sulphur chloride resins; sulphur-aromatic amine resins; fratise; drying oil resins; cellulose and derivatives thereof such as esters and ethers; proteins such as casein, zinc and soyabean protein or leather. The vehicle may include a mixture of solvents with differing evaporation rates. The siliceous polymer may be one or more of acid polysilicic acid esters, such as those disclosed in U.S. Specification 2,404,426. The formulation may also contain dyes or fillers such as finely divided silica, silicon carbide or alumina.

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.

Abstract: 1,272,370. Glare-reducing coating. R. C. A. CORPORATION. 3 April, 1970 [3 April, 1969], No. 15923/70. Heading B2E. [Also in Divisions Cl, G2 and H1] A glass viewing member through which in use an optical image is to be viewed includes on its viewing surface a glare-reducing coating having a rough surface and being composed of a lithium silicate material. The surface of the viewing member e.g. the external surface of the face of a television tube may be coated by (a) warming the surface of the glass screen to 30‹C-100‹C., (b) coating the warm surface with an aqueous solution containing 1-10 weight percent of a lithium-stabilized silica sol, the sol having an SiO 2 :Li 2 O mole ratio of 4:1-25:1, e.g. by spraying, (c) drying the coating, (d) and then heating the dry coating at 100‹C-450‹C for 10-60 minutes. As shown in Figure 1, a cathode ray tube includes an evacuated envelope 21 having neck section 23 integral with funnel section 25, a face plate or panel 27 comprising an optical viewing screen joined to funnel section 25 by seal 29 preferably of a devitrified glass, a luminous coating 31 of a phosphor applied to the interior surface of the face plate 27, a lightreflecting coating 33, e.g. of aluminium applied to the luminous coating 31 and a glare reducing coating 35 having a rough external surface composed of a lithium silicate material. The coating 35 may be produced on the face plate when the face plate is a separate assembly, or when it is sealed to the funnel yet part of the evacuated tube, or when it is part of a tube which has already been evacuated and sealed-off. Alternatively, the viewing member may be an implosion protection plate which is to be adhered to the external surface of face plate 27 by a suitable adhesive.
