Title: Method and apparatus for producing thermoplastic film
IPC: B29C48/12
Filed: 1965-06-17
Abstract: 1,110,598. Making thermoplastic film by extrusion. UNION CARBIDE CORPORATION. 17 June, 1965 [17 June, 1964], No. 25720/65. Heading B5B. Thermoplastic film, e.g. of polyethylene or polypropylene, is extruded at 12 in such a way as to have beaded edges and is taken up by an internally cooled cooling roll 15, an air cushion being maintained between the cooling roll and the part of the film between the beads to prevent surface or other defects such as scratches, gel tack marks, puckers and blotches, The air cushion is obtained by the motion of the roll which may have a matt surface over most of its width for this purpose. The diameter of the roll between the parts contacting the beads of the film may be reduced to increase the separation between the film and roll. Regulation of the quantity of air in the cushion is effected by air knife 18 across the film between the beads at the point at which the beads first contact the roll. This contact is assisted by air jets 20 above each bead. A vacuum knife 22 reduces turbulence at the point where the air cushion is formed. Heaters 24 remove any volatiles from the roll surface. The film beads may be produced by providing the extruder 12 with end plate heaters which causes the plastic to extrude faster at the edges than the middle. The film may be extruded horizontally, vertically downwards or upwards or in an inclination direction. Fourteen examples of extrusion of polyethylene and polypropylene film, some with erucamide as slip agent, are given, together with full details of process parameters.

Patent GB-745269-A (GB)
Title: Improvements in or relating to antenna systems and mounting means therefor
Inventor: BLITZ DANIEL
IPC: G01S7/03
Filed: 1953-09-25
Abstract: 745,269. Radar; aerials. RAYTHEON MANUFACTURING CO. Sept. 25, 1953, No. 26515/53. Classes 40 (5) and 40 (7). An aerial construction suitable for use in a radar having separate transmitting and receiving units comprises an electrical ground plane 10 having two spaced apart apertures therein which form the mouths of two electromagnetic horns 11 and 12, the distance between the apertures being such with respect to the wavelength of operation that the aerials are isolated to a high degree from one another. The horns may be substantially matched to free space and excited in TE 01  mode with the electrostatic lines perpendicular to the line intersecting the axes of the horns. As shown, horn 12 is the transmitting horn and is excited by offset probe 13 surrounded by a sheath of dielectric 15. The probe is fed by coaxial line from magnetron oscillator 19 resiliently mounted between the horns. Horn 11 is used for reception and contains a pair of crystal rectifiers 33 forming a balanced mixer from which an output signal is derived. These crystals are fed out of phase by the received signals and in phase by a signal derived from horn 12 over a coaxial line. This line has a central conductor 36 fed by coupling loop 37 in horn 12 and terminated by attachment to the mixer in horn 11. Part of conductor 36 is surrounded by a layer of lossy material 40 to attenuate the signal and the outer conductor of the line is made up of two halves 41 and 42 designed to form a rigid assembly preventing relative movement of the horns. A cover 45 is provided surrounding the horns and this is attached to a ring 47 which is in turn attached to the support structure 52 which may be the skin of an aircraft. The ring 47 is designed to have a half wavelength slot 48 in it, one side of which is formed in part by the edge of ground plane 10. As the plane 10 is a substantial part of a quarter wavelength thick the junction between it and the ring 47 will be at a relatively high impedance point along the slot and any looseness of the securing screws will thus have little effect in modulating the current flow between the ground plane and the structure 52 and is unlikely to produce spurious signals. The slot is preferably filled with dielectric material. A modified choke structure for use at the edge of the ground plane 10 is described with reference to Figs. 8, 9 and 10 (not shown). The arrangement of the aerial structure with reference to the other units of an F.M. radar is described in connection with Fig. 5 and with reference to a pulse radar in connection with Fig. 6 (Figs. 5 and 6, not shown). Fig. 7 shows the aerial structure 54 fastened to a cylindrical support member 66 rotatable about a vertical axis 67. This form of mounting may be used for a marine navigational radar.

Sept. 14, 1954 [Nov. 10, 1954; June 21, 1954], No. 26683/54. Class 108(3). [Also in Group XXXIV] Rubber-ring-sprung wheels are assembled by an apparatus comprising an annular segmental radially expandable support 6 for the rubber ring 5 and a guided axially displaceable frustoconical expander 1 having a larger diameter end which supports the wheel body 3 with its outer periphery flush with the expander surface. As shown, the segmental support 6 is mounted in a ring structure 8, 9 on which rests the wheel rim 4 carrying the rubber ring 5, the structure 8, 9 being supported-on columns 7. For rail wheels already fixed on an axle, the expander 1 receives the axle end, when the wheel 3 is clamped to the expander, and may locate the axle journal 21 and emergency running surfaces 32 thereof in one or more centring sleeves 31. Alternatively centring of the wheel body 3 on the expander 1 may be effected by a flange on the expander end fitting within the wheel body recess. The wheel body may be clamped to the expander by bolts 24 which bear, through one or more segments 33, on the wheel body, and extend through apertures in the wheel body and the expander to engage a U-shaped member 27 which in turn bears, through wood blocks 29, against the underside of the expander, and circlips a recessed portion of a draw rod 13<SP>1</SP> to couple the latter to the expander. The draw rod 13<SP>1</SP> is pressure-fluid operated to draw the expander through the ring 5 until the ring snaps into its recess in the wheel body periphery. The rod 13<SP>1</SP> extends into the expander and may have a screw engagement with the axle end. In alternative arrangements the clamping bolts 24 may be outside the expander bearing on the wheel body through two centrally bowed transverse rods straddling the wheel axle, or, in the case of separate wheels, the draw rod may extend through the wheel hub, and a clamping disc bearing on the wheel body, and circlips may be applied to the rod above the disc and below the expander to effect clamping of the wheel body.

Abstract: 444,484. Recovering natural gas. RANNEY, L., Petrolia, Ontario, Canada. Sept. 17, 1934, No. 26685. [Class 55 (ii)] Natural gas is recovered from coal and other carbonaceous deposits in situ by gaining access to such deposit and subjecting it to a heat treatmeni appreciably below the temperature at which destructive distillation commences. The gas is thereby caused to exude or to flow into the pore spaces or passages in the deposit and so facilitate recovery. A tunnel 3 with sapping tunnels 4 may be driven into a coal seam, and to increase the exposed surface of the coal charges may be ignited in borings from the sapping tunnels. A concrete barrier 5 is then constructed in the tunnel 3 near the shaft 1. A second tunnel system 9, 10 of a similar character is then completed and hot gas is pumped through pipes 13, 12 so as to raise the temperature of the coal 10‹ F. or more, and upset the unstable equilibrium by which adsorbed gas is held in the cool. This gas is driven into the tunnels 4, 3 and withdrawn through pipes 6, 7 to holders located either in the mine or at the surface. In a modification, a system of wells may be used either above or in conjunction with a tunnel system.
