Abstract: 1,195,476. Motor vehicles. ROLLS-ROYCE Ltd. 2 April, 1969 [11 April, 1968], No. 17534/68. Heading B7D. A motor land vehicle 10 having running wheels 14, which may be driven by a rotary engine, is additionally provided with legs 17 which are normally out of contact with the ground (full line position), and may be brought into ground contact (intermediate dotted position), with a force sufficient to make the vehicle jump over an obstacle in its path with the wheels 14 clear of the ground (lower dotted position). Four legs 17 provided with wheels 18, are disposed symmetrically and longitudinaly with respect to the vehicle body and connected by levers 19 to pistons 20 in cylinders 21 to which a charge of compressed air may be introduced by a compressor. The piston and cylinders on each side of the body are in a common housing. Alternatively, all four legs may be operated by a single piston and cylinder. A locking device prevents the charge being released until required and the pressure may be varied to control the torque imparted to the legs. Some energy may be restored by compression when the vehicle returns to the ground after a jump, the wheels 18 during the jump also leaving the ground. Alternatively an explosive charge may drive a mechanical system having an output connected with the legs, or the energy supply from a flywheel, or metallic, rubber or liquid springs. A variable slipping clutch may be provided to control the torque supplied to the legs with these alternatives. In a further embodiment, the vehicle is a motorcycle provided with two running wheels, two legs and means on the fuel tank to support the rider during take-off and landing. The fuel tank in each embodiment is disposed near the centre of gravity of the vehicle.

Patent GB-810503-A (GB)
Title: Improved speed-responsive hydraulic pressure generator
IPC: F16H61/02
Filed: 1956-06-12
Abstract: 810,503. Change-speed control. GENERAL MOTORS CORPORATION. June 12, 1956 [June 29, 1955], No. 18106/56. Class 80 (2). [Also in Group XXIX] A speed-responsive pressure generator to change the gear ratio of a variable-ratio transmission on an engine at a predetermined engine speed, comprises a gear pump 20, delivering a predetermined quantity of liquid per pump revolution through a small diameter conduit 32 having fixed restricted exhausts 28, 42 so that the pressure in a chamber 34 adjacent the exhaust 42 remains substantially constant irrespective of the viscocity of the liquid over a particular range of engine speeds. The pump is engine driven through the transmission and the pressure in the chamber 34 acts on a piston 38 in opposition to a fluid-pressure proportional to engine throttle position to adjust a control valve connected to the piston and controlling a fluid-pressure servomotor to alter the gear ratio at a predetermined engine speed to operate a clutch or brake. In a given example exhausts 28, 42 are 0.120 and 0.125 inch diameter respectively and the conduit 32 between the exhausts is 2 feet long and 5/16 inch diameter. At low viscosities, e.g., oil at 250‹ F., the pressure drop through the conduit 32 is small, about 10 lb. per square inch from 50 to 40 lb. per square inch and the whole pump delivery is exhausted approximately equally through the two exhausts. At high viscosities, e.g. oil at 0‹ F., the pressure drop through the conduit is much larger, with a much larger proportion of the pump delivery being exhausted through the exhaust 28 due to the much higher pressure existing at this point with the result that the pressure in the chamber 34 remains substantially the same, viz. 40 lb. per square inch. These figures apply to a pump speed of 1400 R.P.M. but over a range of speeds the pressure in the chamber 34 it is stated will be substantially independent of viscosity. A relief valve 46 is set to relieve the system at a pressure in excess of the pressure in the chamber 34 plus the maximum pressure drop in the conduit 32.

Title: Improvements in or relating to the separation of minerals
IPC: B03D1/012
Filed: 1938-06-20
Abstract: 515,601. Concentrating ores; cements. SMIDTH & CO AKTIESELSKABET F. L. June 20, 1938, No. 18281. [Class 82 (ii)] [Also in Groups III and V] The separation of minerals from argillaceous ores is effected by froth flotation in an aqueous pulp to which is added as depressing agent a lignin sulphonate, e.g., calcium or sodium lignin sulphonate, preferably in conjunction with an alkaline substance such as soda ash. The tailings from the froth flotation process may be dispersed with lignin sulphonate and concentrated by further froth flotation or by hydraulic classification in a classifier or, preferably, on a concentrating table. The process is applicable to argillaceous limestones. marls, chalks, &c. and phosphate ores, particularly where the ore has to be ground very finely to liberate the constituent minerals; a particular application is to remove sufficient of certain consitutents of the ores to render the residue suitable for cement manufacture. A calcite ore may be dispersed with a lignin sulphonate and alkali and then subjected to stage froth flotation using as a collecting agent saponified tall oil, as described in Specification 478,275, or emulsions of oleic acid or high melting point fatty acids such as fish oil acids. particularly the stabilized emulsions described in Specification 515,606: the frothing may be controlled by addition of a frothing agent such as cresylic acid or a mixture of branched and straight chain aliphatic monohydric alcohols, obtained, with methanol, by the catalytic hydrogenation of carbon oxides. Reflocculation of the tailings may be prevented by a further addition of a lignin sulphonate, and aluminium and magnesium silicates separated from the tailings by hydraulic means or by froth flotation using a flotation agent giving in solution a positive ion with a long-chain group, e.g. dodecyl amine hydrochloride. as described in Specification 515,608. The remainder of the tailings may then be added to the flotation concentrates to give a raw material for cement manufacture. Alternatively the cement raw material may be obtained by conditioning a pulp of the calcite ore with the dispersing agent and then subjecting it to stage flotation with a positive ion reagent to remove the aluminium silicates as described in Specification 515,609. Specification 426,423 also is referred to.

Filed: 1923-07-18
Abstract: 227,480. Huebner, J. July 18, 1923. Liquids, treating with; designs, producing; crape effects, producing; edges, treating; bronzing and the like.- Fabrics and yarns especially those made of or containing cotton are treated with a solution of cellulose in ammoniacal cupric oxide and are then mercerized with or without tension before or after treatment to remove the copper. The mercerization may be replaced by a treatment with sulphuric or hydrochloric acid of a strength in excess of that employed in ordinary souring processes. The cellulose solution may be applied by padding, printing, stencilling, &c., and it may be mixed with mordants, colouring matters, pigments, mica, metal powder, &c. White or coloured resists may be employed to confine the action of the cellulose solution and, or, the mercerizing-agent, mordant, or dye. When a solution containing 1 1/2 -2 per cent of cellulose is employed, a transparent effect is produced, and if the morcerization is effected without tension, the fibres are permanently, contracted or shrunk. With a solution containing about 4 per cent of cellulose, a highly lustrous silk-like opaque effect is produced. If the cellulose film is allowed to contract during the subsequent operations, highly lustrous crimp or crape effects are produced. If the solution is applied in stripes along the selvages, the appearance of umbrella cloth having lace inserted is produced, and of the mercerization is effected without tension crimp or crape effects are produced. Crape effects may also be produced by carrying out the mercerization and, or, the subsequent drying with greater tension in the direction of the weft than in the direction of the warp.
