Title: Bearing and frequency measuring system
Inventor: ROBINSON STEPHEN JOSEPH
IPC: G01S3/14
Filed: 1962-10-18
Abstract: 1,014,037. Radio direction-finding; frequency detectors. MULLARD Ltd. Oct. 18, 1962, No. 39540/62. Headings H3A and H4D. A system for simultaneously measuring the bearing of a distant transmitter together with the frequency of the radio-frequency energy radiated by the transmitter comprises an aerial arrangement in the form of two linear aerial arrays arranged orthogonally to each other, means for measuring in each array the phasedifference angle of the signals induced in two of its aerials by the incident energy, and means for deriving from such measurement two signals representing mutually perpendicular co-ordinates of a vector having an amplitude proportional to the frequency of the incident energy and having an argument representing the angle of incidence on the aerial array of the incident energy. Considering the pair of aerials Y and Z in Fig. 1, the phase sifference between signals induced in them by a wave E is given by where # is the wavelength and d the distance between Y and Z. Putting where c is the velocity, this becomes # y =k f  cos #, where f is the frequency. Similarly the phase difference between signals in aerials W and X is given by # x =k f  sin #. The phase difference between two signals may be measured by a discriminator which gives output signals proportional to cos # x  and sin # x . Further pairs of aerials with spacings of 4d, 16d and 64d may be used in conjunction with further discriminators to determine the sines and cosins of 4# x , 16# x  and 64# x . These signals may then be processed as described in Specification 1,014,035 to give the value of # x  in digital form, and a similar system gives #y. The digital values of # x  and # y  may be converted to analogue values and fed to the deflection plates of a cathode-ray tube; the angular displacement of the spot then gives the bearing of the transmitter, and the radial displacement indicates the frequency. Specification 953,430 is referred to.

Title: Vehicle seats
IPC: B60N2/90
Filed: 1973-08-22
Abstract: 1436134 Adjustable backrests H R TURNER (WILLENHALL) Ltd 15 Aug 1974 [22 Aug 1973] 39721/73 Heading A4J [Alsoin Division E2] A vehicle seat has a backrest which is adjustable in one direction against a biasing force but which may be moved beyond a predetermined position in the opposite direction without operation of the biasing force. The biasing force may be provided by a scroll spring 32, Fig. 3, one end 33 of which is engaged in a slot at the end of a tube 13 and the other end 34 of which engages an abutment 35 on a bracket 14b. The tube 13 is fast with a plate 15b which in turn is fast with the backrest, while the plate 14b is fast with the seat frame and is apertured to pivotably mount the tube 13. The spring thus acts to rotate the backrest anti-clockwise with respect to the seat frame until:- (a) the spring is relaxed whereupon the end 34 leaves abutment 35 (b) an abutment 36 on plate 15b engages end 34 while the spring is still stressed to carry it out of engagement with abutment 35. In either case the seat back is free to pivot forwardly (i.e. for admission of rear seat passengers). The seat back may be locked in a desired "in use" position by the mechanism of Fig. 2, which is preferably on the opposite side of the seat from the scroll spring. A toothed track 19 affixed to the seat bracket 14a is engageable by a pawl 17 rotatable on tube 13. An abutment 29 on the pawl engages a surface 28 on plate 15a to lock them with respect to clockwise rotation of the backrest, while clockwise rotation of the backrest with respect to pawl 17 is allowed after release of a catch 26. The setting of the pawl 17 with respect to track 19 may be altered by bodily raising the seatback until pawl 17 and track 19 disengage. To this end the aperture in plate 14a which receives tube 13 is elongate and a cam 20 engages a cam follower 23 on the tube to perform the displacement.

Abstract: 953,326. Disc brakes. DUNLOP RUBBER CO. Ltd. Sept. 27, 1960 [Dec. 2, 1959], No. 14004/59. Heading F2E. In a disc brake assembly of the kind having a self-servo action each friction element 21 is engaged by one end of a strut 26 the other end 29 of which bears against a part of the non- rotatable brake support located forwardly of the friction element 21 in the direction of rotation 14 of the brake disc 13 about the point of engagement of the strut with the brake support such that the rotational effect and drag of the brake disc upon the pad during braking causes the self-servo effect such that the friction element is constrained to move in an oblique or arcuate direction towards the disc thereby to provide a self-servo action. As wear of the friction element takes place, the angle # between the face of the brake disc and. a line passing through the points of engagement of the strut 26 with the friction element remains substantially constant. The means for achieving the contact between the end of the strut 26 and the brake support may take the form of a sector-shaped end 28 having a smooth surface 29 which rolls on the flat surface of an insert 31 set in a recess in one arm 3 of a brake calliper member. Alternatively, the aforementioned connection may be achieved with a rack-and-pinion device as shown in Fig. 5. Reference has been directed by the Comptroller to Specification 688,382.
