Title: Vehicle axle and disc brake assembly
Inventor: CLAYTON JEFFREY CHARLES
IPC: F16D55/00
Filed: 1964-07-18
Abstract: 1,116,047. Axles; brake dispositions; vehicle wheels. BIRMIDAL DEVELOPMENTS Ltd. 19 July, 1965 [18 July, 1964], No. 29941/64. Headings B7C, B7D and B7H. [Also in Division F2] In an axle and disc brake assembly for a motor vehicle, a plurality of discs 13 is rotatable with and axially movable of a rotary shaft such as a half-shaft 19 of the vehicle and adapted to be gripped between axially movable pressureplates 14 and housed in a closed stationary housing 10 which is adapted to be secured to a fixed axle casing 17 of the motor vehicle to form a rigid continuation of the axle casing and which supports road wheel hub bearings 24 on a hub bearing casting extension 15. Two wheel rims 26 are bolted to the wheel hub 23 carried by the hub bearings 24. The stationary housing 10 comprises a hollow cylindrical casing 12 surrounding the discs 13 and the pressure-plates 14 and a backing-plate 11 is rigid with and closes one end of the casing by means of which the stationary housing is adapted to be secured to the axle easing, the hub bearing casting extension 15 being coaxial with the casing and rigid or integral with the other end of the casing. The discs 13 are splined on a cylindrical drivemember 28 mounted axially on, for rotation with, the rotary half-shaft 19 and the pressureplates 14 are splined to the interior of the closed stationary housing 10. The discs and pressureplates are normally urged apart by compression springs 34 between the outer edges of the adjacent pairs of pressure-plates and the multiplate brake is actuated by means of a pneumatically or hydraulically operated flexible diaphragm 37 of a diaphragm piston (not shown). In an alternative embodiment (Fig. 3, not shown), the brake is water-cooled to dissipate the heat generated when the brake is applied. To achieve this the drive member 28 is adapted to receive water into its interior from a reservoir when the brake is applied and to distribute the water therefrom centrifugally, by rotation of the drive member with the rotary shaft, through apertures in the wall of the drive member to the interior of the hollow pressure plates 14 or directly on to the friction surfaces of the pressure plates and discs.

Title: Synchronising circuit
Inventor: AYLOTT ERIC ROBERT
IPC: H04L25/24
Filed: 1962-08-03
Abstract: 940,619. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. Aug. 3, 1962, No. 29960/62. Heading H4P. In a telegraph regenerative repeater means is provided for maintaining each inspection pulse substantially at the centre of each bit in spite of bias distortion. Advancing and retarding the inspection pulse is by the addition or removal of a pulse in a train of clock pulses which are counted. Clock pulses at the rate of n pulses/bit are fed to unit 4 from a generator 1. The pulses then pass to dividing unit 5 which divides by n and gives a sampling pulse during each bit period. The telegraph input signal is differentiated and the transition pulses switch T4 to state 1 causing counter 12 to count, in the forward direction, the clock pulses. When a sampling pulse is produced by unit 5, counter 12 starts to count in reverse and, as it counts through zero, unit T5 is set to " 1 " causing a phase detector 9 to be set to " late," i.e. to remove a pulse from the clock train when a transition pulse is fed to it. Such a transition pulse resets T4 to " 1 " which in turn sets counter 12 to zero, ready to count forwards again. However, if no such transition occurs, i.e. if the next bit is the same as the first bit, unit 9 is inoperative and counter 12 continues to count backwards. When the next sampling pulse arrives T5 resets to " 0 " and sets the phase detector 9 to " early." The subsequent transition pulse causes a pulse to be inserted in the train at the input of unit 5. The regenerated signal appears at the output of unit T2.

Pile-fabric looms. - Relates to looms of the kind described in Specification 175,450 for weaving pile fabrics wherein selected pile warps are raised and are caused to form loops over longitudinally-arranged hooks or needles, the loops being cut subsequently to form pile, and comprises means whereby the hooks are enabled to be operated without undue lateral strain when weaving a patterned fabric in which a number of differently-coloured pile threads are employed for each hook and pass through a single reed space. According to the invention, each hook has the main part of its shank placed centrally with respect to the group of pile threads with which it is associated, the forward end of the hook being off-set or cranked by cutting away the under edge as shown at 3, Fig. 1, by off-setting the upstanding part of the hook as shown at 6, Fig. 4, or by inclining or canting the upstanding part of the hook. as shown at 8, Fig. 5. Where the hook is turned about the line a-b, the forward part is moved to one side of the group of pile threads. The pile threads may be moved laterally and the dents of the reed may be reversed, in the manner described in the prior Specification.

Abstract: 1,013,684. Twisting wires together. PACKAGE SEALING CO. (EXPORT) Ltd. Nov. 26, 1962 [Aug. 26, 1961], No. 30860/61. Heading B3E. A package binding machine includes a powerdriven twister pinion which is driven through a transmission controlled by means which allow unlimited rotation of the twister pinion in one direction but prevent rotation of the twister pinion in the opposite direction beyond the position of ejection of the tie. Overlapping portions of flattened wire laid around a package are twisted together to form a tie by a pinion 20a rotated three revolutions and a further fraction of a revolution to overtwist by an air cylinder D and then returned through the angle of overtwist by an air cylinder B so that the tie may be ejected. A rack 33 driven by the cylinder D turns, through a gear 32, a shaft 24 carrying on a radial arm 28 a pawl 31. The pawl 31 engages notches 18 in ratchet discs 25, 26 carried by a gear 23 to rotate the gear 23 and thus the pinion 20a. A cam 34 on the shaft 24 operates an adjustable trip valve T at the top of the stroke of the air cylinder D to reverse the stroke of the cylinder D and start the stroke of the cylinder B. The cylinder B moves a pin 39 up a slot 38 to engage the upper end of a recess 27 in the ratchet disc 25 to push the gear 23 back until a stop pawl 35 engages on notch 18. The return stroke of the cylinder D carries the pawl 31 past a roller 44 on a lever 43 to rock the lever and thus move ejector bars 41 connected to a frame 42 to eject the completed tie from the pinion 20a. A cam 45 on the arm 28 actuates a trip valve V near the end of its downstroke to continue the automatic sequence of operations. A knife 53 carried at the upper end of a tube 48 lifted by a cam 53a on the shaft 24 severs the wire during the overtwist. Specification 1,013,685 is referred to.
