Patent GB-1304555-A (GB)
IPC: G07C9/00
Filed: 1970-11-16
Abstract: 1304555 Credit card systems; vending machines OMRON TATEISI ELECTRONICS CO 16 Nov 1970 [20 Nov 1969 17 Jan 1970] 54417/70 Headings G4V and G4X A credit card system has means for receiving a predetermined portion of a living human body and means for establishing that the portion is living and belongs to the correct user of a credit card inserted in the system. In the embodiment of Fig. 1, a hand H placed as shown covers a photosensitive device 36 and blocks light from a source 35. The blocked area is given a digital value by an analogue-to-digital converter 39 and this is passed to gate 41. Simultaneously light from a source 37 is reflected by a finger tip to a photosensor 38, consequent pulsations in the output of the photosensor being characteristic of those of a living human body. A corresponding pulsating output of an amplifier (46), Fig. 2 (not shown), produces an output from switching circuit (49) which acts as a further signal at gate 41. The output now obtained from gate 41 is compared with a value representing the area of the palm of the true owner of the card derived from the card placed in reader 43. If the values are equal the comparator delivers a suitable output signal. Instead of palm area, fingerprint characteristics may be used by replacing device 36 by a well known fingerprint detector. In the embodiment of Fig. 3 (not shown), the resistance of a finger is measured by electrodes (13); it is stated that a living finger has a typical resistance between 500 ohms and 1 megohm. Mention is made of the system being used in conjunction with an automatic vending machine or an automatic cash dispenser.

Title: Process and device for applying pliable tapes to irregular surfaces
Inventor: CUPERY MARTIN ELI
IPC: B29C63/00
Filed: 1967-11-30
Abstract: 1,201,956. Winding tape on to a core. M. E. CUPERY. 30 Nov., 1967 [12 Dec., 1966], No. 54670/67. Heading B8G. To apply a soft pliable tape of an unsintered fluorinated polymer to an irregular surface of a generally cylindrical object, such as a pipe thread, the end of the tape is applied to the irregular surface of the object and the tape is stroked with a brush moving circumferentially of the object with sufficient force to cause the tape to adhere to the object. In Fig. 1 the roller 14 can be biased temporarily upwards against spring means to permit a threaded pipe fitting 15 to be inserted between rollers 11, 13 and 14 that rotate at a low synchronized rate to rotate the pipe fitting 15. On pressing switch 87 the tape feeding roller 8 is set in motion and a brake 72 is withdrawn from a wheel brush 12, the wheel brush 12 being driven by a tubular member through which the shaft 16 of the roller 11 extends. The brush 12 rotates at a speed greater than the pipe fitting 15. When the roller 8 feeds the tape 1 to the junction between the fitting 15 and the wheel brush 12 the tape is rubbed into the threads of the pipe fitting 15. When about one-fourth to one-half of the circumference of the fitting 15 has been covered with the tape 1 the electrical switch 87 is released to stop the roller 8 and permit the brake 72 to stop the brush 12. Continued rotation of the pipe fitting 15, however, causes the tape 1 to continue to be wound on the fitting 15 and in so doing the tape is brushed into the threads of the pipe fitting by the now stationary brush 12. Finally a switch 88 is operated to cause a cutter 10 to sever the tape, the roller 14 is raised, and the fitting 15 is removed.

Title: Improvements in methods and apparatus for the rolling of billets, slabs and the like
IPC: B21B31/02

Abstract: 1,134,772. Rolling. SCHLOEMANN A.G. 16 Dec., 1966 [24 Dec., 1965], No. 56433/66. Heading B3M. Billets or slabs are reversibly rolled by a vertical and a horizontal stand in tandem, the rolls of the stands being shifted axially between each rolling pass to move different roll grooves into alignment with a fixed rolling line. A billet is guided in direction A along V-grooved rollers 1, and is rolled in two steps by the rolls 3 and 4 of a vertical stand 2 and the rolls 12 and 13 of a horizontal stand 11. Before the billet is reversibly rolled in direction B the rolls are shifted to bring new roll grooves into line with the guide rollers. The billet, in each pass, is rolled to a diamond section and then to a square section, an intermediate guide 8a being moved transversely between each pass. The stand 11 is supported on lever mounted rollers 16 for axial movement of the stand, together with the rolls 12 and 13. The rolls 3 and 4 however, are shifted vertically within the stationary frame 2, and are able to be removed from the frame using wheels 6 which can run on rails 7. For rolling slabs the grooved rolls may be replaced by other rolls, and retractable cylindrical guide rollers 22 and 23 used in place of the grooved ones. Round bars and sections may also be rolled.

Abstract: 1,209,109. Polymer emulsion. CELANESE CORP. 4 Dec., 1968 [5 Dec., 1967], No. 57502/68. Heading C3P. Aqueous polymer emulsions are prepared by copolymerizing an alkyl ester of a polymerizable alpha beta ethylenically unsaturated monocarboxylic acid with at least one comonomer containing an ethylenically unsaturated group, one comonomer at least being an ethylenically unsaturated carboxylic acid in an aqueous medium in the presence of a free-radical catalyst and a surfactant, to a degree sufficient to initiate polymerization and then allowing the polymerization to continue without supplying further heat until the polymerization temperature peaks. The product is then cooled to below the initiation temperature, further quantities of the monomers and surfactant are added, and the mixture is again heated sufficiently only to initiate polymerization, the polymerization continuing without the supply of heat until the heat generated by the reaction is insufficient to cause a further rise in temperature, when the reaction is completed by heating below 100‹ C. Finally with the pH of the polymer emulsion at 7 to 10, a resinous or resin forming imino compound is added. In the examples, the following copolymers are prepared: (1) a copolymer of methyl methacrylate, ethyl acrylate, methacrylic acid and optionally methacrylamide; and (2) a copolymer of vinyl acetate, ethyl acrylate, dioctyl maleate and acrylic acid. These copolymer emulsions are mixed with one of the following imino compounds: (a) dihydroxy dimethylol ethylene urea; and (b) dimethoxy methyl urea. The resultant emulsions are suitable in paint formulations containing one or more of titanium dioxide, talc, the basic silicate of white lead, or calcium carbonate.

[Also in Divisions G1 and G3] A detector of infra-red radiation comprises two semi-conductor elements 11, 12 mounted on an insulating plate 13 with a metal shield 14 preventing the radiation from reaching one element 12 which is used to control the temperature of the detector and the change in resistance of the other element 11 is used to indicate the intensity of the radiation. The semi-conductor material exhibits a large change of resistance for a small change in temperature around a particular characteristic temperature. Suitable materials are vanadium dioxide, divanadium trioxide, titanium monoxide or silver sulphide. In the instrument shown in Fig. 4, the detector is mounted at the bottom of a cylindrical tube 21 which is coated internally with a black resistive film energized through electrodes 23, 24 to provide heating of the detector. In operation any change in the resistance of the shielded element is detected at 25 and electrodes 23, 24 energized in a way to return the ambient temperature to the characteristic temperature. The tube 21 also acts as a standard black body radiator for calibration purposes. The detector is preferably made by providing cavities in the alumina or quartz plate 13 which are filled with suitable semi-conductor material and the whole plate sintered. If no cavities are provided in the plate the elements are mado in the usual way by vacuum evaporation or sputtering or printing.
