Abstract: 1,192,966. Optical printers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Aug., 1967 [18 Aug., 1966], No. 37621/67. Heading B6W. [Also in Division G2] In a method of projecting symbols from an information carrier by means of digital laser light-beam deflectors, 1, 2, 3 the information carrier H to be scanned is a hologram divided into discrete squares each containing a hologram of a symbol differing in respect of its character, projection position, or both, from symbols stored in the remaining squares. The symbols may be projected in superposition or in different positions, and may comprise colour component images, or different letters for example. Deflectors 1, 2, 3 follow optical modulators M 1 , M 2 , M 3  and light sources L 1 , L 2 , L 3 . In one form, the symbols are projected successively at the same position through which a photo-sensitive surface is scanned in one or two co-ordinate directions. In another form, the symbols are projected a line at a time and are stored, for each line position, in an individual hologram square. The photo-sensitive surface may then be stationary or moved normally to the direction of the lines. In a further form, the symbols comprise squares having n<SP>2</SP> light sources which may "on" or "off" in (n<SP>2</SP>) different ways. The symbols are selectively projected by means of hologram H on to a square of photo-detectors in the same array as the n<SP>2</SP> light sources.

Abstract: 1318287 Vat dyes MONTECATINI EDISON SpA 5 Aug 1970 [5 Aug 1969 10 June 1970] 37756/70 Heading C4P The invention comprises vat dyes having the general formula wherein R is a linear or branched chain alkyl radical with 1-4 carbon atoms. The dyes are prepared by (1) brominating 1-aza-2 hydroxybenzanthrone; (2) alkylating the resulting compound with a dialkylsulphate or an alkyltoluenesulphonate; (3) treating the alkylated compound with an alkali metal sulphide in an organic solvent under reflux and (4) subjecting the resulting thiobis (aza-alkoxy-benzanthrone) to an alkaline condensation by means of KOH in an alcohol under reflux to produce the crude dye. The raw dye obtained is purified by treatment with an alkyl-p-toluenesulphenate and sodium carbonate in a high boiling solvent. Step (1) is carried out using a stoichiometric amount of bromine in excess of that required, (preferably 5-25 mol. per cent excess) in 90-98% sulphuric acid at 40-50 C. and refluxing for several hours. The bromine derivative is isolated by filtering, washing with water and drying. Step (2) is carried out by refluxing the product of step (1) at 50-150 C. in an organic solvent with a dialkylsulphate or an alkyl toluenesulphenate in the presence of an acid acceptor, e.g. sodium carbonate and the alkoxy-bromo derivative isolated by filtering, washing and drying. The product is then heated at 100-150 C. in an inert gas atmosphere for 1-2 hours with a stoichiometric amount of an alkali metal sulphide or polysulphide in DMF or an alkanol (step 3). Finally, the sulphide produced is heated under reflux with an alkali metal hydroxide in an atmosphere of nitrogen and an alkanol as solvent. The solvent is distilled off and air is blown into the hot mass which is then hot filtered. In an embodiment, the bromoalkoxy derivative produced in step (2) may be reacted directly with an alkali metal hydroxide (step 4) thus eliminating step (3) of the process. The dyes give blue shades on cellulosic fibres using conventional vat dyeing techniques.

Title: Improvements in or relating to the coating of electrically conductive members with thermoplastic synthetic resins
IPC: H01B13/12
Filed: 1964-09-16
Abstract: 1,063,899. Coated wire. SIEMENS-SCHUCKERTWERKE A.G. Sept. 16, 1964 [Sept. 25, 1963], No. 37906/64. Heading B2K. An electrically conductive member, such as a copper wire, is coated with a thermoplastic synthetic resin by drawing it through a thixotropic dispersion of the resin, the viscosity of the dispersion in the region where the member emerges from it being reduced mechanically to deposit the resin as a coating, and heating the coated member to drive off the liquid vehicle of the dispersion and sinter and fuse the resin deposited into a homogeneous coating. As described the dispersion comprises 25 to 45% solids content of polythene of particle size not above 50Á in an aqueous vehicle including 10 to 50% of a low molecular weight alcohol and/or a ketone e.g. acetone, and the desired thixotropy is provided by the addition of 1 to 20% of higher aliphatic alcohols or cellulose hydrate, methyl cellulose or soya lecithin. A non-ionic wetting agent such as a polyethylene oxide etherified with an alkyl (e.g. C 9 ) phenol or a C 8 -C 18  saturated or unsaturated alcohol or esterified with a C 8 -C 18  saturated or unsaturated fatty acid may be included. Alternatively an ionic wetting agent may be used which decomposes to non-ionic compounds on heating e.g. ammonium salts of fatty or resinic acids. The dispersion may be stabilized with mercaptobenzimidazole, N:N'-diphenyl-p-phenylenediamine, or 4:4'-vis-(3-methyl-6-tert. butyl thiophenol). A dye may be incorporated in the dispersion. If a foamed coating is desired the dispersion includes a foaming agent such as diazoaminobenzene, diphenylene oxide-4:4'- disulponylhydrazide or benzene sulphonylhydrazide. Typically the wire after cleaning and soft-annealing is led over a roller into the dispersion and is passed beneath an immersed guide roller and withdrawn vertically. Adjacent the point of withdrawal is disposed a stirrer, a shaker or vibrator oscillated by electromagnetic or mechanical means, e.g. compressed air, or an ultrasonic emitter. Alternatively the immersed guide roller may drive via gearing a plastics roller 18 having two sets of teeth directed parallel to the axis and separated by a deep groove along which the wire 2 passes close to the roller axis, a housing 19 extending about the roller. In another arrangement (Fig. 5 not shown) agitation of the thixotropic dispersion is effected by a rotatable tubular plastics member having an internally cut high pitch thread, the wire passing through the tube. After leaving the coating bath the coated wire is passed in counter-current with an inert gas through the furnace simultaneously. Polypropystages at temperatures of 210‹C, 240‹C, and 260‹C. Several coated wires may be passed through the furnace simultaneously. Polypropylene is referred to as another suitable coating material.
