Filed: 1972-11-09
Abstract: 1375274 Laminates JOHNS-MANVILLE CORP 9 Nov 1972 [24 Nov 1971] 51779/72 Heading B5N In a method of producing a laminate of a substrate of bonded fibreglass, a facing outer layer, an intermediate reinforcing layer having openings distributed over its surface and a layer of film adhesive, the outer layer 12, reinforcing material 14 and film adhesive 16 are converged into superposed contacting relationship, subjected to heat and pressure to cause the film adhesive to bond the reinforcing material to the outer layer through the openings in the reinforcing material to form a facing which is then superposed on substrate 10 with the layer of film adhesive contacting the substrate and subjected to heat and pressure to bond the facing to the substrate. Film adhesive may be heated by hot roll 24 covered with polytetrafluoroethylene tape 40 as the layers pass between the hot roll and pressure roll 26 having rubber facing 44 or an opposing conveyer, and the facing cooled by means of rolls 28 prior to trimming the edges in slitter 30 and winding up on mandrel 32. The apparatus may then be modified and substrate 10 carried on conveyer 34 fed through hot roll 24 and pressure roll 26 with the facing to effect bonding. Alternatively the facing may be contacted with and bonded to the substrate prior to cooling. Outer layer 12 may be preheated by passage over roll 36. Bonding of layers 12, 14 and 16 may be effected using a pressure of 5-50 pounds per square inch with the roll 24 being heated to 350-600 F. and the materials being fed at 20-125 feet per minute, and the facing may be bonded to the substrate using a pressure of 5-20 pounds per square inch, a roll temperature of 300-500 F. and a feed rate of 10-50 feet per minute. The outer layer 12 may be a reflective aluminium foil or plastics sheet, the sheet material 14 may be a scrim of glass fibres, organic fibres or wire and the adhesive film 16 may be of a thermoplastic resin, e.g. ethylene acrylic acid copolymer or vinyl resin.

Title: Automatic photomechanical equipment for preparing sculptures
Inventor: NOGRADI MIKLOS

Abstract: 1,079,016. Copying sculptures photomechanically; template followers. CHEMOLIMPEX MAGYAR VEGYIARU KULKERESKEDELMI VALLALAT. Dec. 22, 1964, No.52083/64. Headings G2C and G3N. A three-dimensional sculptured copy of an original such as a person's head is made by taking a series of silhouette photographs of the head, each time rotated round a little further, and then using each photograph in turn as a template for guiding a cutting tool acting on a block of material, a photo-electric device automatically guiding the tool in accordance with the photographic outline. In the arrangement of Fig. 1 (not shown), the subject sits on a rotatable chair whose rotation is synchronized with the operation of the camera, so that about 200 to 360 photographs are taken during one full rotation of the chair. The photographs are then developed, to give a series of silhouette outlines Fig. 5 (not shown). Fig. 2 is a plan view of the sculpturing unit, the block of material T being mounted on a rotatable shaft 27 supported by a stationary frame 10. A lower carriage 11 can move along the frame 10 on rollers, and an upper carriage 12 can move in a direction at right angles on the carriage 11. The silhouettes are provided in the form of a film strip, and are projected, one by one, by a projector unit Fig.3 (not shown) on to a screen 13 supported by carriage 11. A photo-cell 16 is mounted on a shaft 15 carried by a fork 14 secured to the upper carriage 12. The photo-cell can be moved laterally by a rapid-reversing motor 24. As it moves from the light area to the dark area across the silhouette edge, its movement is reversed by the motor, and vice-versa. Thus it executes a continuous vibrating movement across the said edge. Below the photo-cell, and also secured to upper carriage 12, is the cutting tool 21, driven by a motor 20. The undercarriage is given one complete traverse, from end to end of frame 10. During this traverse, the photo-cell guides itself along the silhouette edge, guiding correspondingly the cutting tool 21 which carves off part of the block T. The film now changes to the next frame, i.e. the next silhouette, the shaft 27 carrying the block T rotates the necessary small amount, and the process is repeated. The whole sequence of operations is carried out automatically.

The axles 11, 12 are connected to the frame 10 by spaced lower links 15, 17 and triangulated upper links 16, 18. The springs 19, 20, 21, 22 are interposed between beams 25, 26 on the driven axle 11 and supports 27 on the frame, and the springs 23, 24 are interposed between the trailing axle 12 and supports 30 on the frame. Respective levelling valves 36 arranged on each side of the vehicle and supplied with compressed air through a line 35 are connected to the springs 19, 20, 21, 22 through pressure-limiting valves 37 and to the springs 23, 24 through relief valves 40 so that when the levelling valves open the springs 19, 20, 21, 22 are first supplied until they reach a first pressure which then remains constant while the springs 23, 24 are supplied through the relief valves 40. Relief valves 38 opening at a higher pressure allow transfer of air from the springs 23, 24 to the springs 19, 20, 21, 22 if the trailing axle is overloaded, throttle valves 39 delaying transfer during transient suspension movements. One-way return flow valves 38a, 41 are incorporated in the relief valves 38, 40. The lifting spring 31 is inflated through a pressure-limiting valve 42 and a driver-actuated control valve 43 to lift the axle 12 when running under light load, a non-return valve 45 maintaining a minimum pressure in the lifting spring 31.

Abstract: 1294333 Feeding sheets OPTO GRAPHICS Inc 4 Nov 1969 [8 Nov 1968] 53953/69 Heading B8R Sheet-feeding apparatus, particularly for use in electrostatic copying machines, comprises means for feeding edgewise the end sheet of a stack, and guide means against which the sheet is fed, the guide means having at least one protuberance against which the leading edge of the sheet will impinge and snap over and which, in the event of double feed, will arrest the second sheet. The arrangement can be employed where the sheets are fed from the top or the bottom of a stack, or from one end of a stack when the stack is arranged or its side. As shown, soft-rubber coaxial driven rollers 58 carried by pivoted arms rest on the top of the pile 14 and feed the uppermost sheet 16 forwards into the mouth 38 of a channel 40. Feed rollers 42 engage the sheet as it leaves the channel 40. Circular protuberances 60 are stuck up from the guide 22, each protuberance being aligned with one of the rollers 58. When a single sheet 16 is fed from the pile 14, its front edge engages the protuberances 60 so that it first buckles and then snaps over the the protuberance. If two sheets are moved forward by the rollers 58, the top sheet moves over the protuberances, but the underneath sheet is held back. Lateral guides with pads of foam plastic may be provided at the side edges of the pilesupporting plate 10.

The ingoing gas stream may contain not less than 80% of molecular hydrogen, and not more than 0.5% of moisture. Separation of the iron from the product may be effected by melting, the unreduced oxides being recovered as slag. The apparatus illustrated consists of a vertical reactor divided by perforated plates 15 into a series of fluidized beds, the charge passing intermittently downward through successive beds in countercurrent to the reducing gas stream. There may be provided within each bed a series of vertical baffle surfaces such that there is a surface: volume ratio of 6 to 12 sq. ft. per cubic foot of fluidized solids; these baffles may be in the form of U tubes 46 &c. connected to headers 44, 45 &c. These tubes may be dummy, or may be used to pass a heat exchange fluid through the bed, as by passing the incoming hydrogen before feeding it into the reactor.
