Title: Process for the manufacture of an electrically heated sheet of  transparent material
Inventor: BAUM H
IPC: H05B3/84
Filed: 1971-11-12
Abstract: 1315426 Printed circuits SPIEGELGLASWERKE GERMANIA ZWEIGNIEDERLASSUNG DER GLACERIES DE SAINT-ROCH SA 12 Nov 1971 [13 Nov 1970] 52722/71 Heading H1R [Also in Division H5] The resistance value of a network of heating element strips deposited on a transparent base is adjusted upwardly by reducing the thickness of the strips, over a limited area, e.g. 15-20 cm. central strip by abrasion, chemical means or electrolytically, the original strip thickness being such as to present a lower resistance than required (e.g. 10-20% lower) across the element terminals. A conductive protection layer may then be electro-deposited on the network. A bridge network is used to control the adjusting process in a conventional manner. The strips which may be of silver paste are deposited by serigraphy on to a glass substrate followed by a baking process. The abrasive process may use a nylon cloth and a polishing powder or a felt pad impregnated with pumice powder in an organic binder and the chemical process may use felt band impregnated with a 5% solution of sodium cyanide. In the electrolytic process an acid resistant steel cathode wrapped in nickelsulphamate impregnated glass wool is used, the network of strips forming the anode. A potential of six volts is applied across the anode and cathode. The electrolytic current is interrupted periodically for 0À1 sec. to allow monitoring by the bridge circuit. The final adjusted unit may be used as a heated window for an automobile.

Title: Dyeing method and dye bath
IPC: D06P1/30
Filed: 1964-12-30
Abstract: Substrates, especially fibrous textile materials of polyesters, polyolefines, polyacrylonitrile, polyamides, cellulose acetate and natural and regenerated cellulose, are dyed by a process comprising impregnating the substrate with a dye having the general formula R-[SSO3M]n where R is the radical of a dye which may contain other water-solubilising groups e.g., -SO3M, -COOM or -OH, M is H, -NH4 or a metal, e.g. sodium, and n is 1-4.  Water, formaldehyde and a metallic salt, other than a salt of Mg, Ag or Cu, which is a Lewis acid in the solid state and which is soluble in water to an extent of at least 0.03 mol per litre at 20 DEG C., and subsequently drying and curing the impregnated substrate suitably by heating at 110 DEG  - 200 DEG C. The dyes are thereby insolubilised possibly due to formation of polysulphide linkages formed from the thiosulphate groups.  The dyes may be of the azo, anthraquinone, acridone, vat, triphenyl methane, nitro, phthalocyanine or metallo phthalocyanine series and the thiosulphuric groups may be attached directly to aromatic nuclei of the chromophore group or via a bridge member.  The Lewis acid salt may be a strong mono basic acid salt of a divalent Group II metal, chromium, iron, cobalt, nickel or aluminium.  By using sufficient Lewis acid salt and formaldehyde, cellulosic materials may be simultaneously cross-linked.  Examples are given.

Filed: 1972-11-16
Abstract: 1400873 Grinding AMBAR INVESTMENT Inc 16 Nov 1972 [24 Nov 1971] 52974/72 Heading B3D A method for controlling a grinding process comprise mounting an energy detecting instrument other than a mechanical vibration sensitive instrument in the proximity of a contact zone between the grinding body and that workpiece material and directed at that zone such that the matter and/or energy emanating from that zone can be measured and the grinding process adjusted accordingly. The instrument may measure vibration using a seismic-type transmitter or a laser, thermionic energy, electromagnetic radiation caused by oxidation, radioactivity using a spectrometer, i.e. Geiger-Muller tube, scintillation detector, selenium cell, lead-sulphide cell or the like, or flux density. The signal produced is used to control the grinding condition, such as infeed rate, in conjunction with a dimensional control effected by contact or non-contact measuring instruments such as gauging equipment, or optical indicators, e.g. lasers and masers. The detecting instrument is mounted to be free of vibration and may be adjusted by the dimensional control instrument to compensate for wear of the grinding body.

Title: Direct-positive silver halide materials
Inventor: BARBIER JEAN-FRANCE LEON PAUL
IPC: G03C1/485
Filed: 1969-11-03
Abstract: 1294327 Photographic direct-positive silver halide material EASTMAN KODAK CO 3 Nov 1969 [4 Nov 1968] 53763/69 Heading G2C  A direct-positive silver halide photographic material comprises at least one layer containing nitron (1,4-diphenyl-3, 5-phenylimino-4, 5, - dihydro-1, 2,4-triazole) preferably at a concentration in the range 0À1-2g per mole of silver halide. Nitron may be in the silver halide emulsion layer or an overlayer (ace EX4). The direct-positive material may be produced by chemical fogging or may contain silver halide grains with centres which promote deposition of photolytic silver and which are produced by reducing a portion of a water-soluble silver salt before mixing with a water-soluble halide (see divisional appln. No.24714/72, Serial No. 1294328/72. Reduction of silver nitrate may be effected with stannous chloride, thiourea dioxide, formalin or alkaline arsenite and a small amount of polyvinyl pyrolidone may be added before reduction. Where the silver halide is a bromide the material may additionally comprise an overlayer containing ions displaceable by bromide ions e.g. from silver salts more water-soluble than silver bromide such as silver chloride or silver ferrocyanide. When the over-  layer contains a silver compound it is preferably desensitized to light e.g. by using rhodium ammonium chloride, 1-phenyl-5-mercaptotetrazole, methyl benzotriazole or 4-nitro-6- chlorobenzotriazole (see EX4). These directpositive materials containing nitron tend to form no yellow physical development fog even in extensively used developer baths.
