Title: An improved release device for spring accumulator brakes for motor vehicles
IPC: B60T13/22
Filed: 1950-09-08
Abstract: 687,793. Vehicle brakes. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.- GES. Sept. 8, 1950 [Sept. 24, 1949], No. 22162/50. Class 103 (i). The invention relates to auxiliary parking or hand brakes, particularly for heavy road vehicles, of the type in which the force of a strong spring, normally kept compressed by air pressure, is used to assist the manual effort on the brake by a controlled release of the air pressure, and is concerned particularly with the provision of hydraulic means for releasing the brake after the spring has been allowed to expand and there has been a failure in the compressed air release system. A transmission unit 1, preferably fitted in the driver's cabin, comprises a hand lever 5 operating a pump plunger 6, 7, which sucks oil or other liquid from a reservoir 4 and discharges it through a pipe 3 to a receiver unit acting against the spring in the servo spring cylinder. As shown in Fig. 2, the spring cylinder is such as to exert a tensile force to apply the brakes by rod 28 on release of the air. pressure supplied through connection 31. In the event of failure of air pressure, the spring may be recompressed by hydraulic pressure supplied by the hand pump through pipe 3 acting against a plunger 30 in a cylinder 29 built into the spring cylinder. A modified arrangement is also described for a servo-spring cylinder wherein the spring exerts a compressive force on the brake transmission rods. Alternatively the hydraulic receiver unit 2 may be quite separate from the servo-spring cylinder 42 and connected to the brake linkage by a lost-motion mechanism 43, 44, 45 as in Fig. 4. The transmitter unit 1 also includes a release valve 17, 18 which is opened on full downward movement of the lever 5 and allows liquid to flow back from the pipe 3 by pipe 15 to the reservoir 4. A further release valve 21 which controls flowback from the distributer branch 14 by pipe 19, is held open so long as the normal air release pressure continues to act on diaphragms 23 and thus prevents use of the hydraulic release system so long as the compressed air system is still effective.

Title: Improvements in the production of 1-amino-2-sulpho-4-halogen-anthraquinones
Filed: 1949-08-26
Abstract: 1 - Amino - 2 - sulpho - 4 - bromo- or 4-chloroanthraquinone is made by subjecting an aqueous solution of 1-amino-2-sulpho-anthraquinone to the action of a current of inert gas, e.g. air, carrying bromine or chlorine in gaseous form. Reaction is effected at about 0 DEG  C. and the inert gas is given its bromine content by passing at a temperature of about 130-180 DEG  C. through liquid bromine at preferably 10-25 DEG  C.  Advantageously inorganic salts such as sodium chloride or sulphate or potassium chloride should be present in such concentration that the product is precipitated from solution as soon as formed, c.f. Specification 598,797.  For the above bromination reaction the concentration of sodium chloride quoted is 3-4.5 per cent by weight.  The concentration of 1-amino-2-sulpho-anthraquinone in the aqueous salt solution is preferably from 2.5-4 per cent, advantageously 3-3.5 per cent, by weight.  Bromine concentration is preferably maintained at 0.05-0.07 per cent by weight during bromination, reaction being stopped when it rises to about 0.09-0.1 per cent.  In an example, bromine in dry air is passed for 6-9 hours through an aqueous sodium chloride solution of 1-amino-2-sulpho-anthraquinone at about 0 DEG  C. and when reaction ceases the reaction mixture is heated to about 90 DEG  C. to dissolve the precipitated product, more sodium chloride is added and the product obtained on gentle cooling is filtered off and recrystallized from hot water, the filtrate being recycled for use as bromination reaction medium.

Abstract: 860,546. Differential gear; change-speed gear; positive clutches. FERGUSON RESEARCH Ltd., H. July 8, 1957 [July 24, 1956], No. 22808/56. Class 80 (2). [Also in Group XXXI] A motor vehicle driving gear of the kind in which the engine power is transmitted to the front and rear road wheels and in which a differential gear 25 is interposed between front and rear propeller shafts 22F, 22R includes a reversible shaft 30 having a driving connection 27, 31 with the differential gear, and a pair of one-way clutches 60, 70 interposed between the shaft 30 and one of the propeller shafts 22R to limit the differential action, the over-running member of the clutch 70 being rotated by the reversible shaft 30 while the overrunning member of the clutch 60 is rotated by the propeller shaft 22R. Locking or skidding of the rear wheels or spinning of the front wheels is prevented by the clutch 60 which couples the shaft 30 to the shaft 22R through gears 63, 64 when the speed of the shaft 22R falls in relation to that of the shaft 30. The clutch 70 causes the shafts 22R and 30 to be coupled through gears 73, 74 when the speed of the shaft 22R rises due to spinning of the rear wheels or locking or skidding of the front wheels. The gears 64, 74 have clutch teeth which engage a clutch member secured to the shaft 30 when the gears are displaced against spring action by pressure oil supplied through bores 86, 87. During reverse running, the oil pressure is withdrawn so that there is no limiting action on the differential gear. The gear-wheels 63, 64, 73 and 74 may have helical teeth to assist the clutch action. A gear-box 40 providing direct, reduction and reverse drives and toothed gearing 20, 20A, 21 connect the shaft 30 to a shaft 19 coupled to the turbine of an hydraulic torque converter having a free-wheel controlled reaction wheel and an impeller which is connected to the planetary carrier of an epicyclic gear. The latter has an internally toothed gear ring secured to its casing 15, which is an extension of the casing 13 of the converter, and a sunwheel which may be clutched either to the gear ring to provide a direct drive or to a stationary casing 16 to provide a step-down ratio. The casing 13, 15 has a flexible laminated member 11 connected to the engine crank-shaft 10 while the casing 16 contains the control mechanism for the converter and the epicyclic gear. The shaft 30 may alternatively be driven through only a conventional gear-box. A vane or gear-wheel type pump 90 supplies pressure oil for operating the gears 64, 74 and for lubrication. Each one-way clutch comprises a set of rollers interposed between flattened surfaces on an inner member and the inner curved surface of an outer member, the rollers being mounted in a cage spring-urged relative to the inner member in the opposite direction to that of rotation.

It is preferred that the polyurethane precursors are free of groups reactive with the unsaturated material and comprise a polyisocyanate and a polyfunctional compound containing isocyanate-reactive groups, suitably polydienes terminated -COOH or -OH groups, polyesters or oxypropylated derivatives if diols and polyols, in particular a mixture of poly- (propylene glycol) and oxypropylated trimethylol propane. The unsaturated material is preferably an ethylenically unsaturated monomer which is either monofunctional or polyfunctional with respect to its unsaturated groups. A mixture of a monofunctional and polyfunctional unsaturated material is preferred. Polyurethaneforming catalysts and free-radical forming catalysts may be included in the reaction mixture. In a typical example, oxypropylated trimethylolpropane, poly-(propylene glycol) and 4,41-diphenylmethane diisocyanate were mixed together and to the mixture was added methyl methacrylate, t-butyl peroctoate and dibutyl tri-dilaurate. The resulting solution was charged to a mould, the polyurethane-forming reaction being allowed to proceed to completion and the methyl methacrylate subsequently being polymerized at elevated temperature.
