Abstract: 1484740 Elastic composites BAYER AG 1 Oct 1975 [5 Oct 1974] 40118/75 Headings C3R C3P and C3Q A process for the production of an elastic composite comprises mixing a natural and/or synthetic rubber and/or a non-rubbery elastomeric synthetic resin granulate with a polyurethane binder capable of hardening under the action of water or moisture, shaping the resulting mixture and subsequently allowing it to harden under the action of water or moisture, the said binder being a free isocyanate groupcontaining reaction product of a polyhydroxypolyether and a polyisocyanate which is a polyphenylpolymethylenepolyisocyanate containing from 20-80% wt. of 2,4<SP>1</SP>-diisocyanatodiphenylmethane in an NCO/OH ratio of from 2 : 1 to 15 : 1. The said granulate preferably has a particle size of from 0À5 to 6 mm. and is preferably used in an amount of from 1-20 p.b.w. per 1 p.b.w. of binder. The polyisocyanates may be obtained by aniline-formaldehyde condensation followed by phosgenation followed by fractional distillation. The preferred polyisocyanate, component consists of 0-5% wt. of 2,2<SP>1</SP> - diisocyanatodiphenylmethane, 20-80% wt. of 2,4<SP>1</SP>-diisocyanatodiphenylmethane and 80-20% wt. of 4,41-diisocyanatodiphenylmethane, and has a viscosity of less than 200 cP at 20 C. The preferred polyethers have 2-3 hydroxyl groups and a M.Wt. of 800 to 6000 and may be obtained by the addition of ethylene oxide and/or propylene oxide to starter molecules, e.g. H 2 O, ethylene or propylene glycol, trimethylolpropane or glycerol. The binders generally have an NCO content of 5-15% wt. and a viscosity of from 1000 to 15,000 cP at 20 C. The granulate may be rubber or plastics waste, e.g. from retreading tyres. Optional additives include urethane catalysts, e.g. tertiary amines and organo-metallic compounds; solvents which do not contain any NCO reactive hydrogen atoms; plasticizers; pigments; inorganic fillers such as sand, kaolin, chalk, barium sulphate or SiO 2 ; emulsifiers and flame-retardants. The elastic composites produced may be used as floor or ground coverings or as insulating layers. In the examples an elastic composite in the form of a panel is prepared by spreading a mixture comprising granulated tread surface rubber from car tyres, 1,4- diazabicyclooctane as catalyst and a polyurethane binder which is a prepolymer prepared by reacting polypropylene glycol with a 60/40 mixture of diphenylmethane-4,41-diisocyanate and diphenylmethane-2,41-diisocyanate, in a moulding frame and allowing it to harden in the presence of atmospheric moisture at room temperature.

Abstract: 978,932. Vehicles capable of travelling on land, water and in the air. WESTLAND AIRCRAFT Ltd. Nov. 20, 1961 [Nov. 23, 1960], No. 40349/60. Headings B7A, B7G, B7H, B7V and B7W. A vehicle has a pair of contra-rotating, variable pitch fans 30, 31 in a central forwardly inclined duct 3, driven either with or independently of wheels 13 from an engine 1. The vehicle has a box platform 5 with wells for the wheels and transmission and which constitutes a buoyancy tank when the vehicle travels on water; the wheels then act as paddle wheels and the steerable front wheels produce a rudder effect. Engine air intake and exhaust nozzles 16, 17 are above the water line. An auxiliary water screw and a rudder may be used. On land the vehicle has either two or four wheel drive, Fig. 8 (not shown). Fan hubs 42 incorporate automatic hydraulic pitch control gear to give collective pitch control to fans 30, 31, the gear including centrifugal force and torque sensitive mechanisms, not shown. For limited flight, the engine is connected solely to fans 30, 31. The pilot selects a flight pattern according to the size of the object to be passed, to preset the automatic pitch control gear. The blades are then locked in the flat pitch position and then spun up to the required r.p.m.; the lock is then released to permit the control gear to adjust the blades for flight during which the pilot has limited control over pitch adjustment. The gear apply full pitch to raise the vehicle and then reduces pitch over the climb period, but pitch is then increased to produce a steady descent velocity; the final touch down is controlled by the pilot. The engine can be used to rotate the blades during flight. Tiltable vanes under control of the pilot at the nozzle 11 of duct 3 may be used to increase forward thrust; separate thrust jets located around the vehicle and fed from air reservoirs may be used to control the vehicle in flight. Two by-pass duets 43, Fig. 2, having pressure-operated relief valves, are located at the rear of duct 3 to prevent fan blade stall when the vehicle takes off from water. For travelling over swamps, both the wheels and fans are driven from engine 1.

Abstract: A spinning box is dipped in, or sprayed with, a dispersion of a solid lubricant in a curable synthetic resin, and the resin then cured. Polytetrafluoroethylene is the specified lubricant, and the resin may be a phenolic resin, e.g. a cresolformaldehyde resin.ALSO:In the manufacture of a spinning box from material comprising a curable synthetic resin, a solid lubricant, preferably polytetrafluoroethylene, is incorporated in the resin at a stage before the curing of the resin.  The box may be pre-formed from a plurality of layers of resin-impregnated fabric having a solid lubricant incorporated in the resin of each layer, or only in the resin of one or both surface layers of the box.  The latter construction may be effected by making the box from a continuous length of resin-impregnated fabric having a solid lubricant incorporated in the resin adjacent to at least one of the ends of the fabric length.  Alternatively, a pre-formed box may be dipped in, or sprayed with, a dispersion of the lubricant in a curable synthetic resin, especially a phenolic resin, e.g. a cresol-formaldehyde resin. Spinning boxes so made show a lower power consumption in operation than conventional boxes, facilitate yarn doffing and show less tendency for the deposition of crystals on their surfaces.

Abstract: 1,043,209. Change-speed control. DOWTY EQUIPMENT OF CANADA Ltd. Oct. 9, 1963 [Oct. 30, 1962], No. 41047/62. Heading F2D. A manual lever jointly controls an infinitely variable hydrostatic transmission and a following two-speed constant-mesh gear, movement of the lever in one plane adjusting the hydrostatic transmission and movement in another plane changing the ratio of the mechanical gearing. The transmission comprises a reversible variable displacement hydraulic pump 2 supplying a fixed displacement motor 4 driving tha input shaft 6 of a two-speed gearing having wheels 7, 8 selectively clutchable to the shaft 6 by hydraulic clutch means 9 and constantly meshing wheels 13, 14 fast on an output shaft 15. A control lever 19 is pivotally mounted on a lug 21 by means of a pin 23, the lug 21 in turn being pivotally mounted about its own axis in a support 22. The lever 19 is connected to a rod 26 which determines the displacement of the pump 2. and a valve plunger 17 is urged by a spring 20 into contact with an end 18 of the lever 19. Movement of the lever 19 about the axis of the lug 21 adjusts the position of the rod 26 while leaving the plunger 17 in the same position, rotation of the lever about the pin 23 adjusts the position of the valve plunger 17 while leaving the pump displacement substantially unaltered. The lever is guided in a slot 24 of a gate 25, in the position A the pump displacement is zero and low ratio is engaged in the constant-mesh gearing. Movement of the lever along the slot to position B increases the pump displacement to its positive maximum value, the valve plunger 17 remaining in the position in which a supply conduit 28 from a make-up pump of the hydraulic transmission is connected to a pipe 12 leading to the clutch means 9 and a pipe 11 leading to the clutch means 9 is connected to an exhaust passage 29 to connect the gear 8 to the input shaft 6. Movement of the lever 19 along portion BC of the slot leaves the pump displacement unaltered but moves the valve plunger 17 to a position in which both pipes 11, 12 are connected to the exhaust passage 29, movement of the lever through part CD of the slot reduces the pump displacement,-movement of the valve \ plunger 17 being such that pipes 11, 12 remain connected to exhaust passage 29, movement of the lever 19 along part D, E of the slot opening pipe 11 to pressure line 28 to connect gear 7 to the input shaft 6. The reduction in ratio in the hydraulic transmission from point C to point D of the slot is such that the overall transmission ratio remains unaltered, and subsequent movement of the lever from position E to F of the slot increases the ratio of the hydraulic transmission to give high overall ratio. Movement of the lever 19 through positions B1, C1, D1, E1, F1 of the slot produces the same results as before except that the pump displacement is reversed to give reverse drive.
