Title: Method of coating a backing with a thermo-plastic composition
IPC: B32B15/08
Filed: 1959-03-12
Abstract: <PICT:0862466/III/1> A backing, which may be a metal sheet or a material such as burlap or felt, is coated with a thermoplastic composition by depositing a layer of the comminuted composition on the backing while the latter is continuously moving in one direction, softening the composition and consolidating it on the backing by means of a non-yielding pressure-applying roll working in opposition to a resilient pressure-applying roll.  This consolidates the plastic without causing extrusion.  Suitable thermoplastic compositions include those containing polystyrene, polyethylene, polyvinyl acetate, polyvinyl chloride or copolymers of vinyl chloride and vinyl acetate.  Metal sheets, which may be pre-cut, are given a preliminary coating of adhesive e.g. vinyl resin adhesive, by means of a roll-coater, doctor blade, sprayer or the like.  The comminuted thermoplastic is then applied and softened by heating before being passed through the rolls.  As shown, a backing 2 is provided with a coating of comminuted thermoplastic 3 and is heated by a radiant heater 4 just prior to passing through a roll consolidator comprising a metal facing roller 7 and a metal backup roll 8 provided with a rubber facing 9.  In order to obtain a desired surface configuration e.g. smooth or embossed, it may be passed through a second consolidator 10.  The rollers are temperature-controlled, those of the second consolidator being preferably maintained at a higher temperature than those of the first.  The plastic coating may be caused to work or flow during consolidation by providing the facing roll with an etched or roughened surface; subsequent smoothing may be effected by a second consolidator, or by merely subjecting the surface to a softening temperature.

Filed: 1936-03-23
Abstract: 472,486. Liquid and pulverulent fuel burners. LORENZEN, C. March 23, 1936, No. 8609. [Class 75 (i)] A burner for liquid and pulverulent fuels comprises a rotary valve disc which is moved axially by the air pressure to maintain the fuel and air supplied to the combustion chamber in substantially constant proportions. The rotary valve disc shown consists of two plates 22, 23 secured together by screws 24 and mounted by ball-bearings 21 on a sleeve 18 sliding on a guide tube 14 forming part of a head 5 secured at the top of the combustion chamber 1. The sleeve 18 is pressed upwardly by a spring 13 resting on a support 10 carried by the head 5 until a needle 31 carried by the valve disc closes the outlet of a fuel nozzle 17 carried by the guide tube 14. When a throttle valve 4 in the air inlet 3 of the combustion chamber is opened the valve disc moves downwardly against the resistance of the spring 13 so as to allow fuel from the nozzle 17 and primary air entering through apertures 20 in the sleeve 18 to pass to the space between the plates 22, 23, and secondary air to enter between the divergent wall D of the combustion chamber and the rotary valve. The secondary air is directed by curved vanes 29 on a cap 28 covering the ballbearings 21 to radial blades 27 on the plate 22. The valve disc is thereby caused to rotate and the fuel and air mixture between the plates 22, 23 is discharged through apertures 25 into the secondary air. The fuel is supplied to the nozzle 17 through air inlet 6 past a pressure regulating device 16. The device 16 comprises a piston valve 50 which is moved relatively to fuel passages 45, 48, 49, in a plug 46 by a diaphragm 36 which is subjected on opposite side to the pressure of the fuel and an adjustable spring 39. The combustion chamber may be provided with baffles 35.

Title: Method of and apparatus for spraying
IPC: B05B7/02
Filed: 1953-03-30
Abstract: 734,964. Spray-producers. COLLARDIN, G. March 30, 1953 [March 29, 1952], No. 8647/53. Class 69 (3). A flame spray-gun includes a container 5 from which the spray material is fed to a passage 31e and sprayed from a nozzle cap 27 by a compressed air stream fed to the space between nozzle caps 27, 28. The material flow is controlled by a trigger-operated needle valve 32, and the spray stream is fed axially through a cover 24 which surrounds a tubular burner ring 25. The flow of air and material through the cover induces air into the rear of the cover, which air flows in the direction of the arrows. Fuel gas is supplied to a passage 15 and passes, under the control of a needle valve 36, to a conduit 1 which supplies the burner ring 25. A part of this gas supply is led to a pipe 9 via a valve 10, and the flame from this pipe heats the material in the container. Jackets 3, 6 arranged about the container includes ribs 6a which cause the combustion gases to flow upwardly in one half annular path and downwardly in the other. A baffle finally directs these hot gases towards the spray outlet. Compressed air is fed to the gun at 21 and, under the control of a three-way valve 19, may flow to the passage 33 and the nozzle caps via passages 16 and 14, and simultaneously a part thereof flows to the pipe 1. Alternatively compressed air is fed through a duct 17 and a part 17a to a pipe 2 leading to the interior of the cover. The latter includes a number of staggered baffles and the air is directed in zig-zag fashion around the cover interior before passing through a pipe 29 to the space between the nozzle caps. The cover may contain substances to influence the properties of the material sprayed; it may be cylindrical and hollow, or it may comprise a pipe coil 38, Fig. 4, surrounded by a wall 37. By causing the pipe turns to contact each other the wall 37 may be eliminated. In a further embodiment electric resistances are incorporated in the hollow cover, and the front part of the fuel gas pipe supplying the burner 25 is similarly heated. The rear end of the cover may be closed, and an inert gas supply pipe may open into the space within the inner periphery of the cover. Two spray guns as described may be mounted at an angle to each other so that their spray streams intersect; alternatively two spray nozzles may be mounted as stated and provided with a common cover and ring burner.
