Abstract: 1,011,777. Laminates and laminating. W. J. RUSCOE CO. Aug. 29, 1962, No. 33139/62. Heading B5N. A transparent plastics film which is thermoplastic only above 290‹ F. and is about 0À5 to 10 mils thick, is laminated to a base sheet by applying a solution of a thermosetting rubberresin adhesive to the surface of the plastics film, drying the adhesive by heating, applying the same adhesive to the base sheet and heating the base sheet to about 400‹ F. to dry and partially set the adhesive, then bringing the adhesive layers together under temporary heat and pressure to bond the plastics film to the base sheet. The plastics film may have a coating of vapour deposited metal. The base sheet 1 (Fig. 1) is coated with adhesive 5 and is passed through an oven 7 to dry and partially set the adhesive. The base sheet may be metal or a wire or plastic mesh (not shown). The plastics film 12 with its layer of vapour deposited metal 13 and dried adhesive 23a (Fig. 2) is taken from a reel 14 and is bonded to the base sheet 1 by passing them between a fixed roll 15 and a heated and adjustable roll 16. The resulting laminate 23 is cooled by air at 24 and is taken up on reel 25. The plastics film may be polyvinyl fluoride, a polyester, a polyamide or a fluorinated ethylene copolymer and the vapour deposited metal may be aluminium. A suitable adhesive is a phenol resin modified with nitrile rubber and suitable metal base sheets are aluminium and steel. A design or nameplate may be printed on the film before the vapour deposited metal is applied. The laminate may be used for wall finishes, light and heat reflectors and may be shaped by conventional techniques into articles, e.g. a holder for a rear-view mirror. Specification 1,011,778 is referred to.

Title: Improvements in or relating to fluorescent surfaces and articles
IPC: C03C25/10
Filed: 1945-12-10
Abstract: A fluorescent product comprises glass fibres impregnated with or embedded in resinous binding material.  The fluorescence may be obtained by including in the resinous binding material zinc sulphide, zinc cadmium sulphide, calcium sulphide activated by either samarium, europium or copper in the proportion of 20-35 per cent by weight of the plastic, or by complex dyes dispersed in methyl cellulose and applied to the glass fibres before impregnation with the plastics. Fluorescent organic compounds also suitable are anthracene, phenanthrene and complexes based on mixtures of chrysene, pentacene and naphthacene in concentrations of 1-5 per cent of the plastic, and metallic derivatives of salicyclic acid and hydroxy quinoline.  The metallic salicylate is preferably dispersed in alumina or aluminium hydroxide.  The glass fibres may be made from soda-lime-silica glass in which metals are dispersed in ionic concentrations, e.g. cerium, uranium and silver which give blue, green and green fluorescence respectively. Highly purified cadmium sulphide can also be dispersed to give orange or orange-red fluorescence.  The binding media which may be used include the polymerized methyl ethyl, methyl butyl and methyl octyl acrylic esters, styrene polymers, vinyl compounds and cellulose esters.  Suitable plasticisers having only faint fluorescence include tributyl citrate, dimethyl cyclohexanol and triacetin.  The fluorescent product may be comminuted and used as a moulding powder, or moulded, pressed or rolled into various shapes to constitute lamp shades, light dispersing roofing or ceiling lights, fluorescent screens or blinds, as veneer on the surface of wood, metal, paper, fibre or plastic board, or as an interlayer between glass or plastic sheets for ceiling and wall panels.

Title: Character recognition converter
IPC: G06V10/75
Filed: 1963-08-28
Abstract: 977,165. Automatic character readers. SPERRY RAND CORPORATION. Aug. 28,1963 [Sept. 7,1962], No, 33994/63. Headings G4C and G4R, In a character recognition system similar to that described in Specification 939,433 in which signals derived from scanning the character are applied as parallel samples to a number of correlation networks, the one giving the highest response identifying the character, the highest response is found by detecting when one of the correlation signals reaches a predetermined threshold and then storing them all, a staircase voltage generator then being started to raise all the stored values together until one of them sets a threshold device, the staircase generator then being stopped. The correlation outputs are applied through diodes 36, Fig. 2 to an Or gate 38 which passes the highest signal to threshold detector 40. Just before the end of the scan the detector 40 produces an output serving to back-bias diodes 42 so that the signal values on the several leads are stored in corresponding capacitors 44. At the same time the output from detector 40 starts the staircase voltage generator 46,the output of which is applied to the other sides of the capacitors 44 so that all their outputs rise together. The one that was initially highest is first to exceed to threshold value of its corresponding flip-flop 30. As soon as one of these is set a detector 50 switches off the generator 46 preventing further flip-flops 30 being set. If nevertheless more than one are set the detector 52 gives an error signal. The character is represented by a signal on one of the output leads, successive characters arriving serially and being stored in successive columns of a buffer store each having a silicon controlled rectifier for each possible character. The appropriate rectifier in each column is set and after all the characters are stored, the columns are scanned to read them out to a punch. If the characters were printed on a record card, the punch may punch them in the same card. Circuits are provided to respond to columns having no character or more than one. Alternatively the store outputs may be converted to binary form and recorded on magnetic tape. U.S.A. Specification 3,040,270 also is referred to.
