Title: Improvements relating to motor vehicle power steering mechanisms
IPC: B62D5/24
Filed: 1955-11-21
Abstract: 783,150. Vehicle power steering. DAIMLER-BENZ AKT.-GES. Nov. 21, 1955 [Nov. 19, 1954], No. 33293/55. Class 79(5) A motor vehicle power-assisted steering mechanism comprises means for measuring the torque applied to the steering wheel by balancing the reaction forces which act on the steering box 1 when the wheel is turned, thereby regulating the auxiliary steering force. As shown the invention is applied to a motor vehicle steering gear comprising a steering column 12 carrying a worm 4 supported by bearings 5 in the steering box 1, the worm being engaged by a roller 11 on an arm 10 carried by a spindle 6 connected to an arm 8 for connection to steering linkage (not shown). The box 1 is mounted for limited rotation in brackets 2, 2<SP>1</SP>, the box carrying an arm 13 arranged between abutments 3, 3<SP>1</SP> on one of the brackets. 'The arm 13 is adapted to operate slide valves 14 disposed in a hydraulic circuit between a pump 15 and a servomotor comprising a piston 16 connected by its rod to the steering linkage, whereby manual rotation of the column 12 rocks the box 1 to cause the valves 14 to provide power assistance to the steering. It is stated that mechanical steering is possible during failure of the hydraulic circuit. Various modifications are mentioned: (1) the valve casing 14<SP>1</SP> may be moved by the arm 13, the valves 14 remaining stationary; (2) the steering gear box may be formed as a structural unit with the control valve and the servomotor; (3) the servomotor may be in the form of a hydraulic shock absorber; (4) the pivot axis of the steering gear box may be on line I-I in Fig. 2.

Title: Process for the production of compounds of the anthraquinone series
Inventor: HOHMANN WALTER
IPC: C09B5/28
Filed: 1965-08-04
Abstract: Amino-anthraquinones are produced by reacting a 1-hydroxy or 1-alkoxy-5,8-dichloro-anthraquinone, which may contain further halogen atoms, with a primary or secondary amine so that at least one halogen is replaced by an amine residue.  The chloro-anthraquinone may be reacted with an amine under mild conditions so that one chlorine atom is replaced, and the product reacted with the same or a different amine under energetic conditions to replace one or more further halogen atoms. The product may be subsequently sulphonated, e.g. by sulphuric acid, or carbazolized, e.g. with aluminium chloride, used alone or in conjunction with sodium chloride, a tertiary aromatic base, ammonia or sulphurous acid.  The preparation of certain hydroxy- and methoxy-chloroanthraquinone starting materials is described.

Title: Process for the improvement of textile materials
IPC: D06M13/188
Filed: 1932-12-01
Abstract: Artificial yarns or fabrics made of cellulose acetate or other organic derivatives of cellulose are delustred by first treating with a higher fatty acid particularly oleic acid, and then with hot aqueous liquid or moist steam.  The pre-treatment with higher fatty acid obviates uneven delustring especially with materials which have been lubricated or otherwise treated with olive oil &c. The higher fatty acid may be applied as such, or as an aqueous dispersion; or in solution in an organic liquid which may be a volatile hydrocarbon or a non-volatile liquid such as a glycol ether, a mineral lubricating oil or a liquid glyceride of a fatty acid.  The higher fatty acid may be applied to the yarn at the spinning cabinet or at some later stage in its manufacture, or it may be incorporated in the size to be applied to the warps.  When applied to sized fabrics, the size is first removed by padding, and the higher fatty acid may be contained as an emulsion in the desizing liquid; after application of the higher fatty acid, the material is preferably allowed to stand before delustring.  The Specification as open to inspection under Sect. 91 refers to the use of higher fatty acids as lubricating and finishing agents for yarns and warps, and for the purpose of reducing the tendency for electrification; it states also that the higher fatty acid may be mixed with glycols, ethyl oxybutyrate, and vegetable and mineral oils; and it contains examples for the preparation of a finish comprising oleic acid, diethylene glycol and castor oil, and of oleic acid in solution in monobutyl ether of diethylene glycol containing phospho-lipoid lecithin, and of a size comprising gelatine, dextrin, glycerine, oleic acid, and benzoic acid.  This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 refers to the use of higher fatty acids such as oleic acid as finishing agents for yarns and warps of cellulose acetate &c., and it states that the higher fatty acid may be mixed with glycols, ethyl oxybutyrate and vegetable or mineral oils, and it contains examples of finishes comprising oleic acid, diethylene glycol and castor oil, and of oleic acid in solution in monobutyl ether of diethylene glycol containing phospho-lipoid lecithin, and of a size comprising gelatine, dextrin, glycerine, oleic acid and benzoic acid.
