Inventor: MERCER FRANK BRIAN
IPC: B29C48/08
Filed: 1960-06-15
Abstract: 946,867. Laminates and laminating. PLASTIC TEXTILE ACCESSORIES Ltd. May 31, 1961 [June 15, 1960; June 29, 1960], Nos. 21076/60 and 22727/60. Heading B5N. Plastic netting produced by extrusion, for example as described in Specification 836,555, is laterally stretched, as by stenter apparatus, to produce a narrow elongated mesh, and is combined with one or more warps of parallel yarns, filaments or tapes. As shown, the extruded net X is stretched laterally, to orientate the molecules of the material and produce a mesh of the shape shown, by gripping the edges of the net in clamps G carried on diverging belts H. The stretched net is conveyed to the nip of rollers A where it is combined with one or more warps C1 of parallel yarns, filaments or tapes by the use of adhesive or, when filaments or tapes are extruded, as from apparatus such as D, by direct fusion of the extruded material with the net. Sheet material, which may be fabric or plastic sheet, or paper coated for example soft polythene, may also be fed to the rollers and bonded to the face or faces of the laminate. Various combinations of the different kinds of layer are described, each sheet layer or warp C1 being delivered from a separate roll or extrusion head. The rollers A are driven from an electric motor M through a gear-box T the speed of which can be adjusted to that of take-off from the belts H. Where layers are delivered by extrusion the apparatus is preferably arranged for extrusion to take place downwardly. The netting may be made from orientatable thermoplastic synthetic resins such as nylon, polythene or polypropylene. Adhesives usuable may be rubber latex, bitumen, polythene, polyvinylchloride paste, or viscose solution. One of the Provisional Specifications describes the combination of extruded plastic net in the form of a double layer or of a flattened tube, with warps of spaced tapes which form selvages when the product is slit longitudinately through or between them. Specifications 836,555 and 905,252 are referred to.

Title: Improvements in or relating to mehtods and devices for the production of photographic contact copies
IPC: G03B27/30
Filed: 1959-06-19
Abstract: 874,987. Cutting apparatus. ZINDLER, W., [trading as LUMOPRINT ZINDLER KOMM.- GES.]. June 19, 1959 [Aug. 16, 1958], No. 21168/59. Class 31 (1). [Also in Group XX] In a photographic contact printing apparatus  in which original sheets are fed in contact with a  negative film strip through an exposure device  and images are later formed on a positive film  strip, the length of each original sheet is sensed  for controlling the energization of an electric circuit for cutting the positive film strip into image-bearing sections. As shown diagrammatically, sensing of the front edge of an original sheet by arm 23 actuates switch 25 to energize solenoid 45. The resultant attraction of core 60 and upward movement of double-edge knife 46 produces a cut in the margin of the positive film strip as it moves between guide surfaces 47 and 48. Upon de-energization of solenoid 45 as the rear edge of the original is sensed, knife 46 is urged downwards by spring 62, and a further marginal cut is produced. Whenever one of these cuts is later sensed by an arm 77, a switch 76 is actuated to energize a solenoid 75, core 74 thereof moves arm 70 downwards so as to actuate switch 81, and motor 67 is energized thereby for driving pulley 65, the projection 69 having been removed from recess 68 in cam disc 66 by the said movement of arm 70. Rotation of the pulley 65 is transmitted by a band 64 to a disc 52, and the positive film strip is cut between a vertically movable knife 53 eccentrically mounted on disc 52, and a stationary knife 51. After one revolution of disc 66, projection 69 is spring-urged back into recess 68 (the solenoid then having become de-energized again), and switch 81 is thereby actuated to stop the motor 67. In modifications, the sensing of the original sheet may be performed optically, and instead of making cuts in the positive film strip, other marks may be made such as perforations, stampings, punchings, or paint marks, the sensing means 77 being modified accordingly. Alternatively, " marks " may be made in a magnetic tape or band moving in synchronism with the positive film strip, the said " marks " later being read by a magnetic reading head.

Title: Improvements in or relating to claw feed mechanism for motion picture apparatus
IPC: G03B1/22
Filed: 1935-08-02
Abstract: 460,716. Kinematograph apparatus. KODAK, Ltd., ALBRECHT, H. F., and BRANCH, L. E. T. Aug. 2, 1935, No. 21963. [Class 97 (i)] Engagements of one or more feed claws with the film occur alternately at different levels spaced apart by the height of an image area or an odd multiple thereof ; the arrangement enables films to be fed through a distance equal to half the distance between successive perforations for the production of images of such height, and may be used in the production of images of half the normal height on 16 mm. films having perforations spaced apart at the normal image height. Fig. 2 shows two claw members a, b, each driven by mechanism generally similar to that described in Specification 386,042, which alternately engage a perforation D<2> in the film F and feed the film, at each engagement, through a height equal to half the distance between the perforations. Each claw member is moved by an eccentric on a shaft c<2> and a cam d<2> on a shaft d<1>, the shafts being geared together by a wheel c<3> and a wheel d, having a diameter half that of the wheel c<3>, so that the claws follow the paths shown. The eccentrics c c<1> on the shaft c<2> move in opposite phase and the cams d<2> move in the same phase to render the claws alternately operative. The claw members may be bent so that their claws move in the same plane to engage perforations in a single row on the film, or may be straight and spaced so that each claw engages perforations in a separate row. Feeding may be effected by a single claw member, and the member may be operated by various forms of mechanism. Fig. 5 shows a claw member p moved by a crank-pin p<1> and by a cam h<5> held in engagement with a follower h<3> by a spring h<4> ; the claw member is bent back so that the claw engages the film F from the remote side of it. Fig. 9 shows a claw member l moved by a crank-pin m<3> and by a crank-pin m<1> engaging a slot l<1> formed in the member l. Other constructions in which the claw member is moved by a cam groove and by a crank-pin are described. Each claw member may carry one or two claws.
