Title: Improvements relating to power steering and like systems
Inventor: ADAMS FREDERICK JOHN
IPC: F15B17/00
Filed: 1965-08-06
Abstract: 1,149,175. Vehicle power steering. CAM GEARS (LUTON) Ltd. 1 Aug., 1966 [6 Aug., 1965], No. 33747/65. Heading B7H. A power steering or other servomotor system comprises a primary pump 31, the output from which is normally by-passed through a cut-off valve 40 to a fluid reservoir 33, and an operator's pump 36, operation of which, in one or other sense, generates pressure closing the cut-off valve 40 and directs pressure fluid from pump 31 to actuate a servomotor 38 in the sense corresponding to the sense of operation of the pump 36. Should the pump 31 fail, the pump 36 draws fluid from the reservoir 33 through a oneway valve 35 to actuate the servomotor. Normally however when the pump 36, which is a metering pump, is operated, as by rotating a vehicle steering wheel, the output from the pump 36, at an augmented primary pump output pressure, passes through a duct 37D to close the valve 40 against its spring loading and through a duct 37A to a spool valve, the spool 20 of which is moved in one or other sense by an arm or lever 44 which senses the input torque of the pump 36, and thence through a duct 38A or 38B to the servomotor 38 from which fluid is exhausted through the duct 38B or 38A, the spool valve and a duct 39. The quantity of fluid delivered and thence the movement of the servomotor 38, is determined by the degree of rotation of the pump 36. A suitable combined torque sensor forms the subject-matter of similar Specifications 1,149,173 and 1,149,174. In a modified spool valve (Fig. 2, not shown) passages (20D) and (20E) interconnect the opposite sides of the end lands (20A) and (20B) to provide an end thrust on the valve during operation, which thrust is communicated to an operator through the arm 44 to provide feed.

Abstract: 760,461. Transistor sawtooth generating circuits and pulse. HAZELTINE CORPORATION. Nov. 25, 1954 [Jan. 26, 1954]. No. 34216/54. Class 40(6) In a sawtooth generator developing a non-linear output, a second wave is developed of opposite curvature which is combined to provide a more linear output. Transistor 11, Fig. 1 is maintained in a conducting condition until a positive triggering pulse D is applied to the collector to cause the transitor to switch off, resistor 19 giving a regenerative effect. If the lower plate of capacitor 23 were connected to earth, the upper plate'would rise in potential according to curve E until the emitter potential rises above the base, whereupon the transistor reverts to the on state. During' the cut off period, capacitor 30 is charged negatively over resistor 24 according to curve G so that by returning the lower plate of capacitor 23 to capacitor 30, the potential of the upper plate rises according to curve H. A rectangular waveform F is developed at the collector of the transistor. A resistor 28 is returned to a tap on potentiometer 29 to allow adjustment for different transistors. If the emitter potential is raised sufficiently the circuit becomes selfrunning.

Abstract: 525,812. Course-indicating apparatus. HARGRAVE, J. G., and WILLIAMS, D. C. Nov. 29, 1938, No. 34776. [Class 97 (ii)] In an automatic course-indicating apparatus for vehicles operating by light transmission by which a map &c. of the course mounted to move in its own plane in two directions mutually at right angles can be reproduced on a screen by projection or reflection the means carrying the map &c. is constructed and mounted so that the setting or direction of movement relative to the vehicle and preferably the means for imparting such movement are controllable by a gyroscope and the means for imparting a movement of progression to the map &c. comprises a motor the speed of which can be regulated in accordance with the progression of the vehicle. A toothed ring 11 mounted in ball bearings in the aircraft and kept in fixed orientation by a gyroscope 10, gears with a gear 12 having a shaft 8 mounted in bearings 13 in a casing 14 fixed relatively to the aircraft. Deviations from the straight course of the aircraft therefore cause the gear 12 to ride round the ring 11 and rotate the shaft 8 either directly or through a servo-motor 9. Mounted within the casing 14 is a turntable 15 which is rotated in accordance with the rotations of the shaft 8 by gear 49. A slide 17 is mounted on the turntable 15 so as to be able to move transversely by means of rollers 18 and guide 19 and, at the other end, by bearings 22 slidable over a rod 21. The longitudinal movement comprises mounting the map &c. 30 on the slide 17 so as to be capable of movement on and off rollers 23, 24. The turntable 15, by means of a bracket 31, carries a motor 32, the speed of which can be regulated, automatically or otherwise, in accordance with the speed of the aircraft. The motor 32 drives through reduction gearing a progress wheel 35 bearing on the upper roller of a pair of rollers 26 gripping the map &c. As shown, the motor is an electric one and is driven by means of brushes 33 and contact rings 34 and is arranged to drive in one direction only. In order to obtain the requisite movement of the map both transversely and longitudinally the progress wheel 35 is arranged so that it can be angularly displaced in the horizontal plane and for this purpose a toothed annulus 36 carried by the casing drives through gearing 37 ... 39 a gear 40 carried by the motor casing the progress wheel 35 being carried by a shaft diametrically carried by the gear 40.

Abstract: 621,178. Weftless cord fabric. DUNLOP RUBBER CO., Ltd., and SMITH, H. Nov. 23, 1946, No. 34806. [Class 140] [Also in Group IX] A roller driven by cords, threads or similar materials passing round it has a swingable rod mounted parallel to it and spaced slightly away, so that if a broken cord wraps the roller, the thickness of material on the roller will cause displacement of the rod to a position in which the cords will be held out of contact with the roller. Cords 8 are passed over a stationary guide rod 10, through a comb 10a, beneath a freely rotatable roller 1, to a take-up point, such as a calender. If a cord breaks, it will wrap round and build up on the roller 1 until it makes contact with a rod 6, mounted on arms 3 pivoted on the axis of the roller 1. The rod 6 is normally held above the roller 1 by a stop 4b. Pressure from a broken cord wrapped on the rotating roller 1 will cause the rod 6 to swing downwards against a stop 4a, where it will hold all the cords out of contact with the roller 1. A sheave and chain arrangement may be provided for replacing the rod 6 in its inoperative position.
