Title: Improvements in the production of photographic relief images
IPC: G03F7/04
Filed: 1950-12-13
Abstract: 675,084. Photographic relief images. KODAK, Ltd. Dec. 13, 1950 [Dec. 13, 1949], No. 30440/50. Addition to 573,771. Class 98 (ii). In the method of making a photographic relief image according to the parent Specification, the light-sensitive layer of hydrophilic colloid binder has incorporated therein a polyvinylidene chloride latex or an aqueous colloidal dispersion of a copolymer of polyvinyl chloride and polyvinyl acetate. The latex or aqueous dispersion may be the only synthetic resin present in the light-sensitive layer, or the latter may also contain an aqueous dispersion of a soft acrylate resin, e.g. polymethyl or polyethyl acrylate or a mixture thereof. The latex may be an aqueous dispersion of polyvinylidene chloride containing about 20 per cent by weight of the polyvinylidene chloride of dibutyl phthalate as plasticizer. The hydrophilic colloid may be gelatin or glue, and the mixture may be sensitized with ammonium bichromate. The support may be glass, synthetic resin, cellulose ester, steel, or aluminium, particularly anodized aluminium. The support may be first coated with a primer such as turpentine, coumarone resin, alkyd resin, plasticized cellulose nitrate, an oxidized drying oil, or chlorinated rubber. In example 1, the sensitive composition is made by adding aqueous highly-hydrolysed gelatin to diluted " Saran " (Registered Trade Mark) latex, and then adding aqueous ammonium bichromate and aqueous sodium salt of N-methyl : N-#- sulphoethyl oleic amide. In example 2, the composition is prepared by mixing aqueous solutions of gelatin plus sodium phosphate of polymethyl or polyethyl acrylate dispersion plus " Saran " (Registered Trade Mark), and of potassium chromate, ammonium bichromate, disodium hydrogen phosphate, and ammonium acetate. The coated support is exposed, processed with water, and heated to 130 C. to heat-seal the resin. In example 3, the sensitive composition is prepared by mixing aqueous solutions of (a) gelatin, (b) ethylene glycol monoethyl ether and " Saran " latex, and (c) sodium salt of N-methyl : N-#-sulphoethyl oleic amide, ammonium nitrate, ammonium hydroxide, and ammonium bichromate. In example 4, the composition is prepared by mixing aqueous solutions of (a) gelatin and ammonium bichromate; (b) the sodium salt of an alkylated aryl polyether sulphonate, a dispersion of polyvinyl chloride-polyvinyl acetate copolymer, a dispersion of polymethyl or polyethyl acrylate, and natural rubber latex, and (c) sodium sulphate, the sodium salt of an alkylated aryl polyether sulphonate, and hydroxyethyl cellulose. A hardener such as alum, a swelling agent such as ammonium hydroxide, or an acid or solvent may be added to the processing water. The composition may be used as etching resists, particularly in forming half-tone plates, relief printing plates, and planographic printing plates on anodized aluminium.

Title: Rubber valve
IPC: F16K7/00
Filed: 1959-09-07
Abstract: 896,132. Valves. GOODYEAR TIBE & RUBBER CO. Sept. 7, 1959 [Oct. 20, 1958], No. 30482/59. Class 135. [Also in Group XXXIV] An inflation valve for a tubeless tyre and suitable for insertion in a hole in the wheel rim or in the wall of the tyre consists of a flanged plug 2 of relatively soft _ rubber with a slit 6 for the insertion of an inflating needle, and a sheath 5 having a substantially greater resistance to cutting and abrasion to resist the cutting action of the tyre cords when the valve is mounted in the tyre. In one form the sheath is of rubber compounded to offer high resistance to abrasion and cutting but sufficiently pliable to permit the radial compression and elongation that accompany the insertion of the valve into the hole in the rim or tyre. In other forms the sheath is of lengths of single stranded or cabled wire or cords, preferably monofilament cords of synthetic material, laid around the plug with their axes parallel to that of the plug and embedded in the soft rubber of the plug or in a layer of harder rubber. Alternatively, the wire or cords may be wound spirally in one or two layers or woven fabric laid on the bias may be used, and the sheath may be extended along the facing sides of the flanges 3, 4 and around the periphery of the flange 3. In another form, the sheath consists of flocculent material with its greatest dimension lengthwise of the plug and embedded in a layer of harder rubber. Any of the above forms of sheath may be employed in a further arrangement in which the ends of the sheath are partially embedded in the flanges 3, 4. The slit 6 may be formed initially to extend only from the outer flange 3 to a point corresponding to the inner end of the sheath so that the plug can be stretched axially by a blunt-ended rod to facilitate its insertion into the rim or tyre wall after which the slit may be completed by the use of a cutting tool.

Title: Method of producing wiring patterns in accordance with the so-called printed-circuit technique
IPC: H05K3/14
Filed: 1961-08-25
Abstract: Conducting portions are formed on the insulating base of a printed circuit board, particularly to form the wiring pattern, by spraying the base with ionized metal vapour, such as of copper, from a plasma spray gun.  The plasma spray may be controlled by a magnetic field and guided using a pantograph.  To avoid heating the base, the spray may be applied in small doses. Portions of the base not required to be made conductive are protected from the metal vapour by an apertured mask or template. More than one metal, all having the same atomic structure, may be applied simultaneously to the base. Existing wiring patterns, e.g. of copper, may be reinforced from the vapour of such wear-resistant metals as rhodium, chromium, nickel and palladium.

Title: Improvements in or relating to fluorescent screens for cathode ray tubes and methods of manufacturing such fluorescent screens
IPC: H01J9/227
Filed: 1950-12-29
Abstract: 673,060. Luminescent screens for cathode-ray tubes. RAULAND CORPORATION. Dec. 29, 1950 [Dec. 30, 1949], No. 31591/50. Class 39 (i). A fluorescent screen is prepared by weaving a fabric of threads carrying or containing a fluorescent material, disposing the fabric on a support and dissociating or destroying the thread structure to deposit the fluorescent material on the support. The screen is particularly applicable for the production of colour images using a pattern of threads containing different fluorescent materials, the threads constituting the warp. Cellulose nitrate is dissolved in ether and alcohol or other solvent, filtered and aged and transferred to four separate tanks. Into each of three of these tanks is stirred one of a group of fluorescent materials, e.g. red, green and blue, and the solutions of the four tanks are extruded into warm air to give multiple and single filament threads. A fabric of light mesh is woven with the three separate colour fluorescent threads forming the warp and plain cellulose nitrate threads the weft, the width of individual threads being 0.015 inches. The interior surface of the end face of a cathode-ray tube is coated with a binder, e.g. phosphoric acid or water glass, and a piece of the fabric affixed thereto. The assembly is heated in oxygen and the fabric volatilizes to leave the fluorescent materials embedded in the adhesive. The face is then welded into the end of the cathode-ray tube envelope. A monochrome screen is constructed with both warp and weft containing fluorescent material. In another embodiment glass fibres coated or containing the fluorescent material are used for the warp and the weft threads are of fibre or glass. The fabric is sintered on to the tube face when the fibre weft threads, if used, are volatilized.
