Title: Composite Plastics Materials.
Inventor: KLIENE RONALD IAN
IPC: B29D22/00
Filed: 1966-03-23
Abstract: 1,170,261. Foamed coating. R. I. KLIENE. 10 April, 1967 [23 March, 1966], No. 12911/66. Heading B2E. [Also in Divisions B5 and El] A composite plastics material is produced by heating one side of a layer of powdered theromplastics material such that the side of the produced sheet corresponding to said one side of the layer has a smooth surface and the side of the produced sheet corresponding to the other side of the layer has a rough porous surface, and forming a foam plastics material on the rough porous side of the sheet produced corresponding to the other side of the layer whereby the foamed material penetrates the porous side to form an inseparable physical bond therebetween. The thermoplastics material may be polyethylene, polypropylene, cellulose acetate butyrate, polyvinyl chloride, acrylics. The foam layer may comprise polyurethane. The polyethylene layer may be formed by spreading the powder onto the walls of a closed mould by rotation, the mould being heated from the outside; alternatively the powder may be sintered in a stationary mould, preferably such that one side was impermeable. In both cases a more and more granular structure is produced as the layer increases in thickness. A mixture of powders in which one constituent has a lower softening temperature than the other may be used, the component of lower softening temperature then forming the outer non-porous layer of the sheet and the component of higher softening temperature the inner porous part. The porosity may be accentuated by blending a powdered chemical blowing agent with the powdered polyethylene. In an embodiment of the invention a water tank is made in two parts, the lid and the body of the tank, each being made in hollow form in rotational moulds and then filled with polyurethane foam. The bond between the polyethylene and the polyurethane allows holes to be drilled in the tanks during installation without damage to the inner skin of the tank.

Title: Improvements in or relating to apparatus for controlling the flow of air to and from an inflatable element for ice elimination on wings and other surfaces of aircraft
IPC: B64D15/16
Filed: 1942-09-14
Abstract: 557,995. De-icing aircraft. GOODRICH CO., B. F., and FAIRWEATHER, H. G. C. Sept. 14, 1942, No. 12957. Addition to 545,637. [Class 4] In apparatus for controlling the flow of air to and from inflatable elements mounted upon aircraft parts to eliminate ice in which the elements are successively connected by a rotor distributer to the pressure supply to atmosphere and to a suction device, as described in the parent Specification, the suction is produced by a Venturi tube supplied through the rotor which is driven by an electric motor and is stopped automatically with the rotor in a predetermined position. In an arrangement of inflatable elements on the forward edges of the wings, and the horizontal and the vertical stabilizing surfaces each pair of pipes from corresponding elements on the two sides of the aircraft is connected to one of a number of T-connections 20 which are connected to ports 28 of the casing of the distributer. The rotor 30 of the distributer comprises supply and exhaust passages 35, 37 adapted to register with the ports 28 and respectively connected to the pressure supply pipe 17 and a chamber 27 open at 39 to the atmosphere A further port 29 in the rotor casing leads to a Venturi tube 45, the throat of which communicates with the casing chamber 26 through passages 47 ..... 50, the passage 48 being provided with a non-return valve 52. The rotor is driven intermittently by a Geneva stopmotion comprising a driving disc 60 carrying a pin 61 engaging a toothed wheel 59 on a shaft 55 detachbly coupled to the rotor shaft 32. The disc 60 is driven by an electric motor 25 through worm gearing 64, 67. In operation, the passage 35 registers in turn with the ports 28 to supply the corresponding pair of inflatable elements and is succeeded by the passage 37 by which the elements are connected to atmosphere through the passage 39. The passage 35 then registers with the Venturi tube 45 at which time the passage 37 is blanked and all the ports 28 are open to the casing chamber 26 whereby the inflatable elements are subject to the suction effect of the tube 45. After leaving the Venturi tube the passage 35 is blanked to regain full pressure in the supply pipe before the passage again registers with the ports 28. The arrangement of the passages 35, 37 is such that the axial thrust on the rotor due to the pressure supply and exhaust are in opposite directions and tend to balance each other. In order that when the main switch 71 is opened to stop the mechanism, the rotor may stop in the position in which the passage 35 registers with the Venturi tube 45, an additional switch 72 in shunt with the switch 71 is permitted to open only when a notch in the rotor shaft 32 registers with a slidable pin bearing on a spring urged plunger 73 by which the switch 72 is operated. The flow of warm air through the distributer is thus maintained when the device is not operating.

Patent GB-653019-A (GB)
Title: Improvements in the production of regenerated cellulose yarns and the like
IPC: D01F2/28
Filed: 1948-05-14
Abstract: A regenerated cellulose yarn is obtained by extruding a solution of an organic ester of cellulose, containing a protein or a thermosetting resinous condensation product dispersed therein, through spinning jets into a setting medium, and completely saponifying the cellulose ester in the resultant yarn.  The yarns thus produced are readily caused to adhere to rubber, e.g. in the production of rubber tyres.  Prior to saponification, the yarns may be stretched, e.g. in wet steam to increase their tenacity. The cellulose ester solution may be extruded into a gaseous evaporative medium such as hot air or into an aqueous or other liquid setting medium.  Acetone may be used as the solvent for the cellulose ester. In an example, a solution of cellulose acetate containing a small amount of resorcinol-formaldehyde resin is dry spun and the filaments are twisted and wound on to bobbins.  They are then stretched to about 10 times their original length in wet steam at 130 DEG  C. They are saponified in hank form with dilute caustic soda at 60 DEG C.  The regenerated cellulose yarns obtained are twisted and several ends are doubled with reverse twist to form a cord.  The cord may be used in the production of rubber tyres, hose, and belting.  Instead of cellulose acetate there may be used cellulose acetate-propionate, or cellulose butyrate, and instead of resorcinolformaldehyde there may be used another phenol-aldehyde resin or a phenol-sulphur resin, or casein.  The amount of resin or protein in the regenerated cellulose yarn should be about 0.1 to 5.0 per cent of the weight of cellulose. If the yarns are produced by a wet spinning process, sufficient of the resin or protein should be present in the solution to allow for that which may be removed by the coagulating bath. Allowance may also be made for resin or protein which may be removed by the saponifying medium.
