Title: Improvements in or relating to a machine for sectioning and inserting film frames into aperture cards
IPC: G03D15/10
Filed: 1963-10-01
Abstract: 999,843. Mounting photographs &c. S. ENGELSTEIN. Oct. 1, 1963 [Feb. 11, 1963], No. 38687/63. Heading A4X. In a machine for sectioning microfilm into individual frames and for inserting each frame into an aperture card, the web W of microfilm carried on a reel 14 is fed by rollers 15, 16 along a double-rail track 19 to a film sectioning station provided with blade elements 21, 22 on a pivoted cradle 20 operated by a solenoid 23 and a viewing arrangement to permit alignment of the frame edges with the blades comprises a light source 24, condensing lens 25 on a carriage 26, projecting lens 28, mirror 31 and screen 32, the carriage 26 being movable by a handle 30 to align the optical system with respect to the film, each frame of the film having guide lines which are made to register with centering lines on the opitical reader barrel and the cutting being arranged to remove the junction pieces J between frames. At the card loading station a card 10 is positioned on a platform 33 having a downwardly inclined surface and slotted guide fingers 34A, 34B which hold the card in horizontal alignment with the web W so that as the film is advanced the film frame is deflected and enters the opening between the card and the upper panel covering its aperture. After the film frame has been cut to size by the blades 21, 22 the advance of the next frame into the sectioning station causes the first frame to be pushed partially into the aperture of the card, the cutting of the frames causing removal of junction pieces J which fall into a tray 35. Card 10 is now transferred to pusher device having a piece 38 with a slot 40 to receive the card and a wedgeshaped finger 41 which engages the trailing edge of the film frame and as the card is inserted in the slot pushes the frame into the compartment. A flat spring 42 guides the card into slot 40 but to avoid scratching the film it is retracted by means of a pin 43 which is lifted when engaged by the inserted card. A microswitch 44 having an actuator wheel 45 passing through an opening into slot 40 and engaged by a fully inserted card closes the circuit to actuate the sectioning blades. To avoid errors from the failure of the operator to align the frame correctly an optical safety device can be arranged to interrupt the circuit.

A laminated sheet material suitable as a wall or floor covering comprises a decorated or patterned foundation material, for example a dyed, painted, or embossed cotton fabric, or nylon fabric, or paper, the foundation material having on at least the decorated side a translucent or transparent synthetic resin coating through which the decoration is visible, for example polyvinyl chloride or nylon, and, bonded to the other side of the foundation material, a sponge textured resilient layer, for example foamed polyurethane, foamed polystyrene, or sponge rubber. This layer may be bonded to the foundation layer by an adhesive such as polystyrene cement. A metal foil layer may be interposed between the foundation and sponge layers. The exposed side of the sponge layer may be provided with a hessian or rubber backing.

The casting 11 may be tubular. Rollers 4, some of which are driven, lower the dummy bar 5a, 5b from a mould 1 as the cast bar 11 is formed. When length 5a is lowered into the pivoted receptacle 7, its top is gripped by jaws 10 which either rotate or hold the length against rotation if the upper part of the apparatus (including the mould) is rotated. In either case, screwthreading 6 is exposed and the length 5a released to fall into the receptacle 7  which is tippable about a pivot 8 to discharge lengths of dummy bar or of cast bar 11 severed by a flame or saw 9. The dummy bar lengths 5a, 5b may be introduced into the apparatus, for starting, by use of the receptacle 7 or through the mould 1. Instead of the tipping receptacle 7, there may be a device which moves the dummy or cast bar lengths whilst retaining them vertical.

The liquid level control means comprises a closed end baffle 39 mounted in the sump 38 whereby liquid from the sump compresses air trapped in the baffle 39 when the liquid level in the sump rises, and pressure sensing means 42, 43 responsive to this air pressure. The liquid may be discharged, either through a spray 17 into the drum 14, or through a nozzle 22 into the balancing pockets 22a, by means of a two-way valve 19. The liquid may be discharged from the sump, either to the valve 19, or to a drain 29, by means of a second two-way valve 28.
