Title: A Continuous Process of Coating by Vapour Deposition.
IPC: B65G35/06
Filed: 1967-07-17
Abstract: 1,189,714. Coating by vapour deposition. LIBBEY-OWENS-FORD CO. July 17, 1967 [July 29, 1966], No.32704/67. Heading C7F. In a continuous process of vapour depositing a coating on sheets such as glass or plastics, the sheets are conveyed through inter-connected vacuum chambers of varying pressure conditions where they are cleaned by a glow discharge prior to being coated from one or more evaporation sources. The coating materials may be metal such as Al or Cr, a metal oxide such as Si O 2  or a metal halide. In an example, sheets of glass are first coated with Cr and then with Si O 2 . The sheets may be heated to 200‹ -700‹ F. prior to coating and the evaporation source is preferably heated by electron beam. As shown in Figs. 1 and 2 the sheets are washed in detergent at 11, rinsed and air dried at 12 preferably with air ionized by an A.C. corona discharge. By means of a turntable 14, loader 16 and transfer section 17 pairs of sheets are held vertically in a carriage which grips the top edge of the sheets and conveyed successively through vacuum chambers 26, 28, 31, 34, 40 and 44 at respective pressures of (2 x 10<SP>-1</SP> - 5 x 10<SP>-3</SP>), (1 x 10<SP>-1</SP> - 1 x 10<SP>-3</SP>) for glow discharge; (5 x 10<SP>-2</SP> - 1 x 10<SP>-6</SP>) for preheating; (1 x 10<SP>-4</SP> - 1 Î 10<SP>-7</SP>) for coating; (1 x 10<SP>-4</SP> - 1 x 10<SP>-7</SP>); and (2 x 10<SP>-1</SP> - 5 x 10<SP>-3</SP>) and controlled by valves 25, 27, 29, 32, 36, 45 and 47. The sheets are first dedusted in chamber 23 with ionized air, subjected to a glow discharge in chamber 28 using aluminium electrodes, optionally preheated in chamber 31 and coated in chamber 34 by being conveyed past three vertical rows of vapour sources 41, 42, 43 with four sources in each row. The conveyer in the coating chamber is in three sections, feed section 38 which slows down the sheets at the first coating zone to synchronize speed with that of the constant speed centre conveyer 37, and discharge section 39 which accelerates the sheets for transfer into chamber 40. The coated sheets are finally passed to chamber 44 which is vented to atmospheric pressure, cooled at 48 and conveyed along line 50 to the discharge and recharge point of the loading system.

[Also in Division A5] Gas conditioning apparatus for feeding gas at a required flow rate and temperature, e.g. to a protective suit, comprises at least two vortex assemblies, each including a vortex tube, a gas inlet for introducing gas tangentially into the tube, a hot gas outlet and a cold gas outlet, the hot gas outlet of at least one of the vortex assemblies being such as to give a predetermined gas outlet flow rate and temperature and the cold gas outlet of at least another of the vortex assemblies being adjustable to obtain variable gas outlet flow rates and temperatures, and in which all the hot gas outlets or all the cold gas outlets are connected together so that the gas flows issuing from the connected outlets are mixed together. The gas issuing from the unconnected outlets may be vented to the atmosphere. As shown (Fig. 5) the apparatus comprises vortex tube assemblies 50 and 51 mounted in housing 52 partitioned to form cold and hot end areas 55 and 54. Air is supplied to tubes 50 and 51 by means of manifold 61 connected by pipe 62 provided with shut-off valve 63, to supply conduit 17 (Fig. 1). The cooled air from tubes 50 and 51 is led via manifold 70 to outlet 71 and suit 11. The hot air is vented to the atmosphere by openings 56. The vortex tube 50 is fixed as regards the temperature of the issuing gas and the vortex tube 51 is varied to control the temperature of the issuing gas so that the required temperature of the mixture is obtained. The apparatus may include a valve to direct part of the supply gas directly to the mixing chamber and simultaneously to cut-off or reduce the flow of supply to one or more of the vortex tubes.

The rubber cement is preferably a polydiene rubber cement having a low intrinsic viscosity.  The rubber latex is preferably a latex of an elastomeric copolymer of a vinylcoyl compound and a conjugated diene.  The rubber cement and the rubber latex are mixed in the volume ration of 1:1 to 10:1.  The pH is adjusted by a mineral acid.  Coagulation is effected by steam and/or water having a temperature above the boiling point of the cement solvent, and is accompanied by flashing off the cement solvent.

Abstract: 980,090. Tensioning bolts. P & O PILGRIM VALVE Ltd. March 27, 1961 [Sept. 29, 1960], No. 33382/60. Heading F2H. A device for tensioning bolts 1 comprises a closed space S bounded by parts 7, E capable of relative movement axially of the bolt, a mass of solid, yieldable and substantially incompressible material 8 in the space, and screw means 12 for deforming the material 8 to increase its axial dimension and urge the parts 7, E axially relative to one another to tension the bolt. In Fig. 1, the device is embodied in a nut 5 having an annular channel 6 between the end wall E of which and an annular piston 7 the ring 8 of rubber &c. is located. Plungers 10 bearing on the ring 8 are operated by the screws 12. The nut 5 is tightened by hand or by tommy bar, engaging holes 33, after which screws 12 are turned to displace the piston 7 and tension the bolt. A split-ring 15 inserted beneath the nut maintains the tension after the screws 12 have been released. Plastic deformation of the nut-threads may occur in zone x-x and be effective as a locking device. Tension may be maintained by an adjustable sleeve-abutment engaging screwthreads in the nut, Fig. 3 (not shown). In Fig. 4, the space S is in the head 3 of the bolt, which may be tightened by hand &c. on to an initial split-ring 15. After tensioning the bolt by means of the screws 12, the initial ring 15 is replaced by one of increased size to maintain the desired tension. In a modification, Fig. 5, the space S is of circular cross-section, and rubber plugs 37 are disposed between the plungers 38 and the rubber ring 36. An initial split-ring 15 is located between a flange 34 on the piston 7 and the bolt-head 3, and is replaced by a thicker ring to maintain the tension. In Fig. 7, the device is in the form of a ring 18 to be inserted beneath the nut 5 or the bolt-head. An annular recess 19 houses the rubber ring 21 and the piston 20. Radial screws 25 and plungers 23 deform the ring 21 and, as above, an initial split ring 26 is used. In a further embodiment, Fig. 9, the ring 18 is located beneath the bolt-head 3, and the rubber ring 39 is engaged tangentially by rubber plugs 41 backed by screws 43 and plungers 42. As above, an initial ring 15 is used. A comparator for measuring the tension in the bolt includes a rod 28, Fig. 11, welded to the bolt 4 at the bottom of a blind or through hole 27. The top of the rod is at the same level as the bolt-top in the unstressed condition. A micrometer 44 projected to the desired measurement, is secured to a magnet 45 by an insulating body 46, the magnet holding the tilted micrometer against the rod 28. When the bolt has reached the desired tension, the micrometer assumes an upright position. A lamp 48 and battery 49 in circuit with the magnet, bolt and rod 28, may be used to indicate the point at which a gap opens between the micrometer and rod. Reference has been directed by the Comptroller to Specification 908,360.

A gelatin-containing layer which may contain aqueous formaldehyde or chromic chloride as a hardening agent may be superimposed on layer (iii). Gelatin may be included in layer (iii). A layer of a photographic gelatino silver halide emulsion may be superimposed on said gelatin-containing layer. The polyester film material may be coated successively with the constituents of the layers, each dissolved in a volatile solvent medium, each layer being dried before the next is applied, the drying conditions being such for the layer containing the polyamide and epoxy resins that a partial cure of the layer is effected by reaction of amide and epoxy groups. The said heat-curing step is effected for two minutes at 120 C. or for a shorter period at temperatures up to 130 C. The constituents of layer (i) may be dissolved in methylene chloride, and those of layers (ii) and (iii) may be dissolved in a lower ketone, methanol or toluene. Specification 772,627 is referred to.
