Abstract: 1,192,107. Breaking wire. CONTROL DATA CORP. 30 Aug., 1968 [28 Nov., 1967], No. 41431/68. Heading B3E. [Also in Division H3] Severance of insulated conductive wires arranged in spaced parallel relationship for threading the apertured cores of a magnetic storage matrix is effected by tensioning the wires and applying localized heating sufficient to reduce the tensile stress to an extent that the wires break, the severing process causing the wire ends to be formed with a tapered shape which facilitates their subsequent passage through the core apertures. Fig. 2 shows a matrix of previously threaded cores 26 which are located by suction in a vacuum box 29, the wires being secured by clamps 24, 28 after threading. The wires are insulation-coated copper originating from spools 12 and are positioned in spaced parallel relationship by guides 16 and 20. Tension is applied by operating a pneumatic device 32 to grip the wires and operating a pneumatic device 30 to displace a tensioning device 18. A further pneumatic device 36 is operated to bring a preheated electrical heating device 22 into proximity with the wires, the device including wire spacers 23. When the wires break the form of the wire ends is as shown in Fig. 3, the tapered shape facilitating the passage of the wires through a matrix of cores held in the vacuum box when the wires are advanced by feed rollers 34.

Filed: 1972-09-07
Abstract: 1404809 Cameras EASTMAN KODAK CO 7 Sept 1972 [13 Sept 1971] 41569/72 Heading G2A For normal exposure a camera diaphragm driven by an electro-mechanical transducer is automatically controlled according to scene illumination and for flash exposure, the diaphragm is coupled to the objective in order to be set according to focus adjustment. As shown, a two-bladed diaphragm 12 defines an exposure aperture 25 and an aperture 29 for an assembly 30 comprising two photo-conductive elements 98, 102. Depression of a button 80 closes a switch S 1  to energize the exposure control circuit. A differential amplifier 110 energizes drive coils 112, 114 to adjust diaphragm 18 according to the illumination of element 102. Button 80 also releases a shutter opening blade (44), Fig. 1 (not shown) which opens a timing switch S 2  whereby a capacitor 100 charges up according to the illumination of element 98 (controlled by aperture 29) and via a trigger circuit 92 deenergizes an electromagnet 78 to release a shutter closing blade (46). If the illumination is low a lamp 122 is energized to indicate that a tripod or flash exposure is necessary. Insertion of a flashlamp into a holder 226 rotates a lever 224 releasing a slide 214 so that when button 80 is pressed slide 214 moves leftwards and levers 232, 242 pivot to engage a pin 252 on diaphragm 18. The diaphragm is driven by coils 112, 114 until lever 242 engages a fixed cam 248 the final aperture depending upon the position of a pivot pin 244 of lever 242, pin 244 being attached to a focusing lever 200. Movement of slide 214 also operates switches 222, 222a to disconnect element 102 and connect a fixed resistor 101 in parallel with element 98. Lamp 122 is de-energized to indicate the end of exposure.

Abstract: 1,207,480. Guiding webs. EASTMAN KODAK CO. 21 Aug., 1969 [27 Aug., 1968], No. 41795/69. Heading B8R. A device for maintaining a running web 10, e.g. an endless belt driven by a roller 11, in correct lateral alignment comprises a tracking roller 19 which is supported in a yoke mounted on three legs 31, 32, 33 so arranged that the roller 19 has three degrees of freedom, being pivotable about a steering axis 28 and a swing axis 29 and translatable along the steering axis 28; a spring 36, attached to the yoke 23, biases the roller 19 for movement about the axis 28 in one sense to cause -the web 10 to move laterally toward one end of the roller where the web edge engages a servo mechanism S responsive to the lateral movement to pivot the roller 19 in the opposite sense about the axis 28. The servo-mechanism (Figs. 2 to 5, not shown), includes a pressure roller (37) which bears against the conical surface (35) of a washer (34) engaging the curved edge of the web 10 as it passes round the roller 19 the roller (37) being mounted on a sensing shaft 38 connected to a servo arm 39 and being also attached to one end of a vertical arm 41 whose opposite end is attached to the yoke 23; the arrangement is such lateral movement of the web 10 against the washer (34) causes vertical movement of the arm 41, and hence of the yoke 23, whereby the roller 19 pivots about the axis 28 in a counterclockwise direction. The movement causes the web 10 to move to the right and correct the misalignment. Because of the continuing force exerted by the spring 36 the servo-mechanism S continues to operate thereagainst so that the web 10 is always held in aligned position and does not swing back and forth. The roller 19 translates along the axis 28 to tension the web 10, being urged in this direction by a spring 26, and pivots about the swing axis 29 to keep the tension uniform across the web.

Abstract: 942,075. Photographing relief printing formes and producing duplicate relief or lithographic printing surfaces. E. I. DU PONT DE NEMOURS & CO. Dec. 9, 1960 [Jan. 27, 1960], No. 42520/60. Headings G2C and G2M. A photographic negative is produced from a relief printing forme by providing the relief surface with a layer of a dry pigment, contacting the pigment-bearing surface with a high contrast silver halide emulsion film which carries on at least the contacting side a layer of a soluble polymeric material which is soft or tacky under the conditions of contact so that the pigment is deposited on it from the relief areas, exposing the film to light through the pigment-bearing face, and developing and fixing the film and removing the pigment and polymeric layer with a solvent at any time after exposure of the film. The softenable layer may be non-tacky at room temperature and softened by heating, moistening, or chemical treatment. Examples are hard polyethylene oxides having a molecular weight above 50000; soft polyethylene glycols of molecular weight 1 000 to 24 000; polyalkylene glycol ethers; polyvinyl pyrollidones; polyvinyl acetates; polyvinylpyridines; mixed polyesters; polyvinyl acetals; cellulose ethers; polyacrylamide; polyvinyl alcohol; casein; agar agar; dextran; rubber cement; and glues. Surface active agents may be included if desired to improve adhesion and non-contacting cover sheets may be provided to prevent contamination by dust. Suitable pigments are carbon black, magnesium oxide, black or red iron oxide, manganese dioxide, aluminium or copper powders, and phthalocyanine or azo dyes. The emulsion may be overcoated with an antiabrasion layer which may contain matting agents such as silica, starch or magnesium silicates but preferably the film has no antihalation layer, a light-absorptive material being placed against the back of the film during exposure. The process may be applied to the production of printing plates or cylinders, the resulting negative being used to expose a photopolymerisable printing plate as in Specifications 741,294 and 741, 441 or to produce a lithographic printing surface. Specifications 757,285, 765,893, 786,344, 786,345 and 864,041 also are referred to.
