Title: Improvements in or relating to fluorescent screens
IPC: H01J9/227
Filed: 1955-10-07
Abstract: 817,760. Luminescent screens. SYLVANIA ELECTRIC PRODUCTS Inc. Oct. 7, 1955 [Oct. 7, 1954], No. 28644/55. Class 39(1). A method of preparing a multiple colour line or dot fluorescent screen, particularly for a colour television C.R.T., comprises, for each colour, the steps of coating a glass panel with a layer of a light-hardenable base material which can be light transmitting, exposing designated areas of the coated panel by point-light shadow projection, coating the layer with a further layer of the base material containing a phosphor, exposing the designated areas of the panel by point-light shadow projection, and treating the superposed layers, e.g. by washing, to remove the layers and the phosphor from unexposed areas of the glass panel. The screen can be baked to gasify the remaining base material and to leave only the phosphors. Multiple coatings of the light-hardenable materials containing the phosphors can be used. Lighthardenable materials used are monomeric type dye-sensitised polymers, gelatin-type materials, polyvinyl alcohol, polyvinyl acetate and Kodak Photosensitive Lacquer (KPL). The materials can be applied to the glass panel by knife-coating or spray-coating. The first layer of material is exposed from the coated side of the panel to an arc lamp through a master pattern which can be the apertured mask of the final C.R.T. assembly or a photographic reproduction thereof and the procedure repeated for the superposed layer of light-hardenable material containing a phosphor. The unexposed areas of the two layers are washed away by a solvent which may be trichloroethylene or ketone, or water. The process is repeated for each of the phosphors with appropriate off-setting of the panel in relation to the master pattern. Zinc orthosilicate is referred to as a green-emitting phosphor and calcium magnesium silicate as a blue-emitting phosphor. The light-hardened materials are finally removed by baking at a temperature of about 400‹C. for several hours. The screen may then be sprayed with a permanent binder such as potassium silicate solution, after which floating-on a lacquer base, aluminising by high vacuum evaporation and baking out of the lacquer base can be effected. Reference has been directed by the Comptroller to Specification 788,661.

Abstract: A germicidal composition in powder or granular form comprises a slowly reactive (defined) organic germicidal compound containing the grouping =N.cl and liberating chlorine in aqueous solution, together with a water-soluble iodide capable of reacting with the available chlorine of the germicide to release iodine, said iodide being present in amount sufficient to react with a minor fraction i.e. at least 2 per cent. of the total available chlorine in the germicide. Preferably 2 to 15, and especially 2 to 10 per cent. of the iodide (based on available chlorine) is present. Specified iodides are alkali metal iodides e.g. sodium iodide and potassium iodide, alkaline earth metal iodides and organic hydroiodides e.g. glycine hydroiodide.  Specified =N.cl compounds are chloromelamine especially trichloromelamine; N-chloro ammeline; N, N1 dichloroazodicarbamidine; N- chloro acetyl urea; N, N1 dichlorobiuret; and N-chloro succinimide. Buffers may be added to provide a pH in water of 2.5 to 6.5, and preferably 5.0.  Examples are citric acid and mono sodium dihydrogen phosphate, citric acid per se and monosodium dihydrogen phosphate per se.  Optional additions are inert diluents and surface active agents such as aryl alkyl sulphonates, e.g. sodium lauryl sulphate.  To prevent deterioration on storage the compositions must be dry, but it is preferred to coat the iodide with a water-soluble inert material such as methyl cellulose, ethyl cellulose, a mixture of sodium carbonate and monosodium phosphate, and preferably glassy phosphates, i.e. the water-soluble polyphosphates, e.g. sodium hexametaphosphate. Phosphate coating is 15 to 70 per cent. and preferably 50 per cent. of the iodide.  In one method, 40 mesh potassium iodide is tumbled in a rotating drum, heated with air of 90-100 DEG C. and then sprayed with a 12 per cent. aqueous sodium hexametaphosphate.  In another, the iodide crystals are maintained as 120-140 DEG C. by heating the drum and then sprayed with a 33 per cent. aqueous solution of sodium hexametaphosphate.
