Title: A process for the extrusion of films of thermo-plastic material in tubular form and an apparatus for carrying out the process
IPC: B29C48/90
Filed: 1965-05-14
Abstract: 1,069,219. making tubular films. SVENSKA METALL VERKEN, A.B. May 14, 1965 [May 15, 1964, No. 20478/65. Heading B5B. In making tubular films by extruding molten thermoplastic material downwards through an annular orifice to form a tube and inflating the latter, the extruded tube is cooled by drawing it through one or more bodies or columns of cooling liquid surrounding and contacting the outer surface of the tube and the layer of cooling liquid from the or each body or column of liquid adhering to the outer surface of the tube and carried down with it is caused to be so thin that droplet formation or running of liquid down the outer surface of the tube is prevented by means of one or more annular sealing members surrounding and abutting the tube, the tube being drawn past an edge of the or each of the sealing member under such contact pressure against the edge that the layer of cooling liquid carried downwards by the tube has the required thinness. In Fig. 1 (not shown), a heated thermoplastic material is continuously extruded through the annular extrusion orifice 1 of a die to form a tubular film 3 which is inflated with air at superatmospheric pressure introduced into the interior of the film through the duct 2 in the die. The tubular film is drawn by means of the nip rolls 16 and 17 successively through the central apertures in the bottoms of the vessels 4 and 5 provided with annular dams 6 and 7. Cooling liquid is supplied to the vessels 4 and 5 through the inlets 11 and 12 at a restricted rate and flows over the dams towards the tubular film passing through the apertures in the bottoms of the vessels. The apertures are provided with annular sealing members 9 and 10, each having an annular sealing edge against which the tubular film is urged by the pressure of the air introduced into it. The sealing edges may be integral with the bottoms of the vessels 4 and 5, but are preferably the inner edges of separate annular sealing members 9 and 10 secured to the edges of the apertures in the bottoms of the vessels 4 and 5. The inflation pressure of the film is adjusted so that a coating of cooling liquid is carried down by the film past the sealing edges sufficiently thick to lubricate the film but not so thick as to flow down the outside of the film. The film after leaving the vessel 5 is drawn by the nip rolls 16 and 17 over the converging guides 14 and 15 and flattened to form a web 18 in the usual manner. Cooling liquid removed from the film by the nip rolls is received in the drip tray 19. The sealing edges of the annular members 9 and 10 may be rigid but preferably consist of a resilient material such as rubber. The operative edges of the sealing members are preferably shaped as illustrated in Figs. 2 to 4 (not shown). A wetting agent and/or a viscosity increasing agent and/or an antistatic agent may be added to the cooling liquid.

Title: Method of producing articles simulating irides by a photographic process
IPC: G03C5/22
Filed: 1945-08-09
Abstract: An article simulating an iris for incorporation into an artificial eye is made by photographing a natural iris and producing a relief image thereof in a layer of gelatine emulsion in which a white or light coloured pigment is dispersed and which is provided with a dark backing substance.  The pigment has the effect of scattering incident light in proportion to the thickness of the relief image; in the case of white pigments used with a black backing the scattered light is predominantly blue.  Irides exhibiting other colours may be produced by modifications concerning the colour of the pigment or the dark backing substance or by super-imposition of a coloured varnish layer. It has been found that the prints of irides can be incorporated in artificial eyes made by compression moulding from synthetic plastic materials, particularly the acrylic ester plastics.

Abstract: 870,318. Coil making apparatus. MICAFIL A.G. June 16, 1959 [June 17, 1958], No. 20579/59. Class 35. In an hydraulic press for pressing insulation on straight conductor portions of dynamoelectric machine coils, and comprising several press units (only one of which is shown) arranged in a row and each having hydraulically actuated pressure pistons 15, 22 for the broad and narrow sides of the conductor rectangular cross-section, each unit is connected to a common control valve 4 by which the pistons applying force in at least one direction may be retracted simultaneously and by a definite amount which is equal for all pistons. With the valve 4 in the position shown pressure liquid passes from opening 5 through pipes 1, 2 to press a pressurerelieving piston 6 against a fixed stop 8 whereupon the liquid passes through a spring-loaded non-return valve 10 into the cylinder 11 to make the pressure stroke of the piston 15. The characterizing retraction may then be made by moving the valve 4 to the right by such an amount that the pipe 1 is connected to a discharge pipe 30, whereupon the piston 6 moves back against an adjustable stop 18 permitting a spring 26 to retract the pressure piston 15 by an amount corresponding to the volume of the stroke of piston 6. The working stroke may be repeated by returning the valve 4 to the position shown, or the piston 15 may be completely retracted by moving the valve 4 farther to remove the pressure of the supply liquid from pipe 2 and a piston 7 so that a spring-loaded valve 12 opens to discharge the cylinder 11 via passages 20, 21 and pipes 3, 29. Specification 849,913 is referred to.

Title: Improvements in or relating to game apparatus
IPC: G07F17/34
Filed: 1936-07-30
Abstract: 462,952. Coin-freed game apparatus. WARNER, R. L. L. July 30,1936, No. 21143. [Class 132 (ii)] [Also in Group XVIII] Relates to a coin-freed game apparatus of the kind comprising a cabinet-like enclosure containing a circular rotatable table having receptacles for balls delivered through a shoot onto an annular track surrounding and sloping downwardly towards the table, means being provided for returning the balls for re-use. The invention is characterized in that the balls are projected into the shoot by an electrically controlled hammer device. In playing a game, the player closes a switch 27, Fig. 7, thereby causing a motor 18 to rotate a pocketed wheel 28, Fig. 1, and then drops a steel ball 35 through an opening 38. The ball bridges two contacts 66, 67 in circuit with an electromagnet 47, transformer 16 and rectifying valve 17. The armature 62 of the electromagnet is attracted and a mallet 64 projects the ball through a tube 41 on to a stationary conical runway 13 surrounding the rotating wheel. Whilst the ball is rolling round the runway, the player, by closing the switch 27 may energize a magnet 69, Fig. 7, situated beneath a groove 71, Fig. 1, and deflect the moving ball, or cause it to lodge in the groove, after which the ball may roll into one of the pockets 34, due to loss of momentum or by de-energization of the holding magnet 69. The pockets 34 are bottomless, the balls entrapped therein being caused by the rotation of the wheel to roll upon a platform beneath. To permit the pockets to be cleared of the balls, the platform whereon the entrapped balls roll contains an apertured radial slide 76, Fig. 3. When the coin slide 90 is pushed in, the aperture 78 registers with the pockets 34 and allows the balls to fall through successively and accumulate upon a plate 79 attached to the slide. On the return of the coin slide, the coin falls down a shoot 93 and the balls are dropped down a shoot 84 and run to an external receptacle 86, accessible to the player.
