Title: Improved steering arrangement for motor vehicles
IPC: B62D3/02
Filed: 1960-02-26
Abstract: 897,592. Steering motor vehicles. ALL WHEEL DRIVE Ltd., EDE, F. E., and DEAN, H. F. Feb. 23, 1961 [Feb. 26, 1960], No. 6789/60. Class 79(5). A gear mechanism is provided in the steering column of a motor vehicle and is brought into operation by a rotary member which has two operative positions, one of which provides a direct connection between the steering wheel and the steering gear input shaft, the other of which provides for the transmission of the steering torque through the gear train whereby its sense becomes reversed at the steering gear input shaft. The arrangement enables the vehicle to be steered when travelling in either direction whereby a clockwise movement of the steering wheel produces a right hand turn in both cases. The steering wheel is fixed to a shaft 12 and the steering gear to an input shaft 13. A pinion 21 is rotatably mounted on a bush 22 on the shaft 12 and a pinion 28, which rotates in bearings 30 and 31, is fixed to the shaft 13. The shaft 12 is supported in bearings 15 and 16 and a clutch member 12 is slidable upon splines at the ends thereof. The pinion 21 is in permanent mesh with one half of a pinion 23, the other half of which is in mesh with one half of a pinion 24 (Fig. 4) the other half of which meshes with the pinion 28. The clutch member 20 may be moved along the splines and be brought into engagement with a complementary member in either the pinion 28 or the pinion 21 so as to transmit drive from the shaft 12 directly to the shaft 13, or through the gear train 21, 23, 24 and 28. Gears 23 and 24 are of equal size. The clutch control fork 32 is mounted on a shaft 33 spring urged into a slot 36 in a boss 37, the slot having a cam surface whereby the shaft 33 is moved backwards and forwards. A spring detent member is provided to locate the two operational positions of the boss. A spring controlled plunger 43 provided in the boss 27 co-operates with flats upon the gearing casing and operates a switch which energises a solenoid which serves to cut off fuel from the engine in the positions in which the steering wheel is not connected to either driving position. An instrument panel may be fixed to the boss 37 and the instruments are the right way up when the wheels steered are in the front in the direction of travel.

Title: Television scanning systems
IPC: H04N3/36
Filed: 1942-05-22
Abstract: 555,773. Television. STANDARD TELEPHONES & CABLES, Ltd. May 22, 1942, No. 7007. Convention date, June 6, 1941. [Class 40 (iii)] A television transmitting system in which optical images are intermittently projected on the surface of a photo-sensitive electrode, comprises means for projecting successive portions of each transient image on corresponding areas of the electrode surface and means for scanning the said areas in turn with an electron beam for converting the images into trains of electrical waves, the rate at which the successive areas are illuminated being greater than the rate at which they are scanned ; this provides the extra time needed to pull a film down when a film is being transmitted. As shown in Fig. 1, a rotating shutter 7 with slits 9 exposes one line or set of lines of a film 4 to the light from a lamp 6, a condensing lens 10 is provided between the lamp and the film, and a focusing lens 11 between the film and the electrode 2 of an iconoscope 1 ; a strip of light passing through a slit 9 is first focused upon the upper edge of the electrode 2 and moves down a short distance before the downward scanning of the upper portion of the electrode begins. According to the invention, the strip of light is made to move downwards slightly faster than the scanning beam. In a modification, the rotating shutter 74 is replaced by a reciprocating shutter with a single slit in combination with a rotating shutter preventing passage of light during the return stroke of the oscillating shutter ; the reciprocating shutter is operated by a cam. Specification 479,551 is referred to.

Title: Process of Resolving DL-Carnitine Nitrile Halide
IPC: D06N7/00
Filed: 1969-02-10
Abstract: 1,198,974. Resolution of DL-Carnitine nitrile halides. TANABE SEIYAKU CO. Ltd. 10 Feb., 1969 [12 Feb., 1968], No. 7016/69. Heading C2C. DL-Carnitine nitrile halides are resolved by forming a supersaturated solution of the halide in a solvent, which is preferably water, an alkanol such as methanol, a ketone or a mixture thereof, and increasing the amount of one of the optical enantiomers in the solvent by adding the enantiomer to the solution either prior to cooling the solution to produce the supersaturation or by seeding the solution, or both, whereupon the predominant epimer crystallizes out. The process may be continued by again forming a supersaturated solution from the mother liquors by addition of more racemate and treating with the optical antipode of that originally crystallized, and can be repeated successively to separate each of the enantiomers in turn. Examples detail the isolation of D- and L-carnitine nitrile chloride, and L-carnitine nitrile bromide from the racemates.

Title: Improved process for cracking oils
Filed: 1929-03-05
Abstract: 331,569. Dubbs, C. P. March 5, 1929. Hydrocarbons, cracking.-In an oil cracking process of the type in which oil is passed under pressure through a heating coil 11 to a separating zone 17 where substantially all the fractions vaporisable under the pressure are separated and fractionated in a dephlegmator 10 while the residual oil is withdrawn continuously through lines 20, 20<1>, 20<11> without coming into contact with the condensate from the dephlegmation zone, or with fresh oil, polymerisation of the residual oil in the zone 17 is controlled by keeping the level of the oil as low as possible and by regulating both - the rate of withdrawal of the oil from the zone 17 and the dissipation of heat therefrom. In this manner the amount of sludge in the residual oil is maintained below 6 per cent and preferably below 2 per cent. In an example, the oil is only kept in the separator 17 for half an hour and the residual oil is cooled by flashing it under vacuum in a known manner in a flash chamber 44. The vapours from the chamber 44 pass to a dephlegmator 6 to which crude oil is fed from a pump 3 and the condensate and topped oil therefrom are pumped to the heating coil through a line 13. The vapours from the dephlegmator 10 pass through a line 30 to a condenser 32 and receiver 33 from which part of the condensate may be returned to the dephlegmator 10 through a line 38 or alternatively to the flash dephlegmator 6. Part of the crude oil may also be delivered to the dephlegmator 10 through a line 8. In an example, distilled Ventura California crude oil of 19 degrees gravity (A.P.1) is heated to a temperature of 905‹ F. under a pressure of 150 lbs. per sq. inch. The withdrawal of the residual oil from the chamber 17 is controlled so that only 2 per cent of sludge is shown by the Benzol, centrifugal test. A withdrawal temperature of 525‹ F. is maintained at the outlet of the dephlegmator and about 40 per cent pressure distillate is produced on the basis of the crude oil treated which distillate contains about 75 per cent of 437‹ F. end point gasoline having a benzol equivalent of 50-55. The residuum amounting to about 37 per cent of the raw oil has a gravity of 10.7‹ (A.P.1) and contains about 2 per cent sludge coke representing less than 0.15 lbs. per barrel of oil treated.

Patent GB-951543-A (GB)
Title: The manufacture of cellulosic fabric structures
IPC: D06M15/423
Filed: 1961-03-01
Abstract: Crease-resistant fabric structures are made by joining at least two woven, knitted or non-woven cellulosic fabric segments having a free, unjoined edge and impregnated with a cross-linking agent for the cellulose which will not react with itself upon storage or the application of a temperature of below 100 DEG C. to form the structures and curing the structures while the fabric carries unreacted cross-linking agent sufficient to improve its crease-resistance, e.g. while not less than 30% of the cross-linking agent remains unreacted.  The cross-linking agent which may be a "reactent-type" resin, e.g. methylated methylol urea, N-substituted methylol triazones, methylol-N-substituted triazines and methylated and unmethylated methylol ethylene ureas or 1,2-propylene ureas, may be applied to the cellulosic fibres in the form of raw fibre in staple or continuous filament form, tans, yarns, fabrics or regenerated cellulose fibres in the gel state after spinning, as an aqueous solution containing 4-25% by weight of the cross-linking agent and 10-50, by weight based on the cross-linking agent of a latent catalyst, e.g. magnesium chloride, zinc fluoroberate and magnesium perchlorate.  The aqueous solution may also contain hand builders, lubricants and water repellants, e.g. polyvinyl alcohol, acrylic polymers, silicones, polyethylene glycol stearate and polyethylene.  The treated fibres may then be dried and stored at a temperature below 100 DEG C.  The impregnated fabric or fabric made from the impregnated fibres or yarns may then be cut to form the fabric segments which may be joined to form the fabric structures by sewing with a thread or yarn itself impregnated with the unreacted cross-linking agent, by the use of a latex cement or by heat and pressure in the case of fabrics containing cellulose acetate fibres. Garment linings may also be impregnated with the unreacted cross-linking agent.  The fabric structures may then be moistened with water by spraying or steaming until their moisture content is raised to 20-100% based on the dry weight of the fabric if desired arranged in creases or pleats, and then cured by heating and pressing at a temperature of 130 DEG -170 DEG C.  Textile materials comprising cotton, linen, regenerated cellulose, cellulose acetate, propianate or butyrate or carboxymethyl or carboxyethyl cellulose fibres alone or in admixture with up to 50% by weight of nylon, polyester or acrylic fibres may be treated. Specification 878,655 is referred to.
