Title: Anti-wheel locking device
IPC: B60T8/24
Filed: 1972-03-15
Abstract: 1383553 Controlling vehicles ROBERT BOSCH GmbH 15 March 1972 [16 March 1971] 11940/72 Heading B7H [Also in Division F2] In an anti-wheel-locking device for the brake system of a motor vehicle comprising a regulating valve (as shown, one for each wheel, 14 to 17), a sensor (as shown, one for each wheel, 18 to 21), and a control device 22, transducing means is provided which includes a potentiometer which is automatically adjustable in dependence on deviations of the longitudinal axis of the vehicle from the direction of motion of the vehicle (see Division F2). The signal from the transducing means may be dependent on the value of the angle through which the steering wheel is rotated during turning, or on both the value and direction of the angle. Alternatively the transducing means may incorporate a horizontal pendulum which governs the potentiometer when the vehicle's axis deviates from the direction of motion during normal steering or skidding or when the vehicle is on a banked road; in this case also, the signal may depend on either the amount of deviation or both the amount and direction of the deviation. As shown, both transducers are provided, at 24<SP>1</SP> and 35<SP>1</SP> respectively, and each provides a signal depending on amount and dierction of deviation. The effect of transducer 24<SP>1</SP> on braking is such that in the case of, e.g. a steered turn to the left, the slip of one or both wheels on the right of the vehicle is reduced, so a turning moment which assists steering is created around the vertical axis of the vehicle. Switching means may be provided (see Division F2), so that only the " horizontal-pendulum " transducer 35<SP>1</SP> is in circuit when the driver steers in a direction to control a skid, while only the " steering " transducer 24<SP>1</SP> is in circuit when the driver steers around a curve in the normal way.

Patent GB-355256-A (GB)
Title: Improved process for rendering textiles water repellant
IPC: D06M13/188
Filed: 1930-04-16
Abstract: The water-repelling properties of scoured cotton, washed wool, artificial silk, and other textile fibres are improved by subjection to treatment with esterifying agents under such mild conditions that there are introduced the radicles of higher fatty acids in amount not exceeding twice the content of such radicles in the natural fibres. By this means there is reintroduced into the fibres radicles that were removed during the cleaning process or during the process of manufacture; and the radicles so introduced need not necessarily correspond with those previously extracted or removed, thus the radicle of lauric acid may be introduced into cotton.  The esterifying agent which may be a fatty acid chloride or anhydride may be dissolved in an organic liquid provided the latter does not dissolve or swell the fibre, in particular the cellulose or cellulose esters or ethers of which artificial silk fibres may be composed; or it may be employed in the form of an emulsion in water, dilute alcohol, &c.  Further, in the esterification the use of powerful auxiliary esterifying means such as alkali is to be avoided, the esterification being assisted by the addition of a weak organic base. In examples, threads or fabric are treated at 60-80 DEG  C. with a 5 per cent solution of stearyl chloride in benzene, to which diethylaniline has been added; or the textile material may be boiled in a 2 per cent solution of palmityl anhydride in benzene; and the esterification may be assisted by the addition of a small quantity of pyridine; cotton wool is impregnated with an emulsion prepared by melting a mixture of palmitic and stearic anhydrides with vegetable gum, adding ammonia solution, and diluting with water.  Specification 313,616, [Class 2 (ii), Cellulose &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the fundamentally different dyeing properties of the treated materials, and to the use of divalent acids such as adipic acid as the esterifying means.  This subject-matter does not appear in the Specification as accepted.
