Title: Improvements in or relating to speed dependent electric control devices
IPC: F16H63/02
Filed: 1960-11-17
Abstract: 960,385. Electric measuring and control systems. REGIE NATIONALE DES UNSINES RENAULT. Nov. 17,1960 [Nov. 20, 1959], No. 39568/60. Heading G1N. [Also in Divisions F2, H2 and H3] An electrical control system sensitive to speed, pressure and the position of a control, more particularly for the change speed gears or clutch control of a motor vehicle comprises an alternator coupled to a rotary shaft and producing an output which is fed through a rectifier, a Zener diode and an integrating capacitor to a amplifier so that a response is obtained when the output voltage exceeds a threshold value. In the gear control system of Fig. 1 the output of an engine driven alternator 1 is fed through a potentiometer 7 and a full wave rectifier 9 to a Zener diode 10 followed by an integrating capacitor 15 and a transistor amplifier 18. When the speed of the rotor exceeds a predetermined value the output voltage obtained from the alternator is sufficient to render the Zener diode conductive and so operate an electromagnetic device 21 for operating the change speed mechanism. The axial position of the magnetic rotor 2 of the alternator may be varied by operation of the accelerator pedal so that the alternator output decreases as the pedal is depressed, so raising the speed at which the gear change is effected. The same effect may be obtained by causing the accelerator pedal to vary resistance 4 (Fig. 8, not shown) in which case the axial position of the rotor may be varied by a pressure sensitive capsule having a diaphragm 2b (Fig. 9) mechanically coupled to the rotor shaft and forming part of a pressure sensitive capsule coupled to the engine induction system. By making the rotor longer or shorter than the field windings it may be arranged that the first part of the movement of the accelarator does not alter the alternator output and in addition, arrangements may be made so that complete depression of the accelerator prevents the gear shift until an even higher speed is reached. A manually operated slider 8 adjusts the speed at which gear shift normally occurs and a control for adjusting the change up and down speed differential may short part of the potentiometer. Provision may be made to compensate for effects due to temperature changes in the alternator and transistor circuits and it is suggested that the transistor amplifiers may be replaced by a magnetic amplifier.

Title: Disc brakes for vehicles
Inventor: GODDARD ARTHUR
IPC: F16D55/224
Filed: 1961-11-04
Abstract: 986,972. Disc brakes. GIRLING Ltd. Dec. 18, 1962 [Nov. 4, 1961], No. 39570/61. Heading F2E. A disc brake for vehicles comprises friction pads and means for applying them to opposite faces of a rotatable brake disc are associated with a stationary dirt shield 10, which protects the inboard side of the disc and takes the torque on at least one friction pad through torque transmitting means when the brake is applied but does not take any of the clamping load urging the friction pads into engagement with the disc. One of the friction pads 16 is located in a radial gap 11 in the dirt shield 10 and the friction pads 17, 18 are guided for movement towards and away from the disc on pins 14 which are carried by a rigid block 12 secured to the dirt shield 10 and spanning the radial gap to form the torque transmitting means. The friction pads are mounted on rigid backing plates 16 in which notches 15 are formed for sliding engagement with the pins 14. The pads may be applied to the disc by complementary clamping levers 19, 21 pivoted at one end 22, an actuating lever 23 being pivoted on one clamping lever adjacent to its free end and being coupled by a tie rod 25 to the free end of the other clamping lever 21. Resilient fingers 27 engaging in slots in the clamping lever move these levers outwardly away from the disc when the brake is in the off position and the coupling between the actuating lever and the tie rod may incorporate a manual or automatic adjuster to compensate for wear of the friction pads. The brake may be actuated hydraulically as well as mechanically by an hydraulic actuator 31 arranged between a bracket 32 on the actuating lever and an abutment 33 on the clamping lever.

A hub D is secured to a shaft C by a key comprising coacting wedge members A, B, the co-operating surfaces of which have serrations 31, 32 preventing relative transverse movement. The members A, B are adjusted longitudinally to tightly engage the walls of the keyways in the hub and the shaft, the bases 26, 27 of the keyways having a clearance from the adjoining faces of the key. In order to accommodate mis-matching of the keyways or to permit slight rotary adjustment of the hub of the shaft, shims may be interposed between one or more of the key faces and the corresponding keyway walls. To permit the remaining sidewalls of the key to bear properly against the keyway walls when shims are employed, metal must be removed from the keys to correct the face angles, and in order to reduce the amount of metal to be removed shallow relief areas 2, 4 are formed in the upper faces of the key. Relief shoulders 20, 21 are formed on the shaft. In a modification the key and keyway are of generally rectangular cross-section instead of hexagonal as shown, and the key may be further modified by tapering the height of the members A, B, so that they firmly engage the basal walls of the keyway as well as the side walls. Transverse pins may be provided towards the ends of the key members to facilitate their adjustment for wedging or removal.

Abstract: 1436245 Carbon fibres KANEBO Ltd 4 Sept 1973 [8 Sept 1972 15 Nov 1972 (3)] 41563/73 Heading C1A [Also in Division B1] Activated carbon fibres able to catalyse the oxidation of carbon monoxide have a surface area of 800 to 3000 m<SP>2</SP>/g. and carry at least 0À05% by weight, preferably 0À05 to 30%, calculated as the metal and based on the weight of the fibres excluding the active catalyst ingredient, of one or more of palladium, ruthenium, rhodium and platinum, as the free metal or as a compound thereof, as an active catalyst ingredient. The carbon fibres may be derived from phenol resins, polyacrylonitrile, cellulosic, and pitch fibres, especially a novolac resin or a mixture of a novolac resin and a pitch, the novolac content being at least 30% by weight. In a preferred method a melt-spinnable carbonizable resin is mixed with elemental Pd, Pt, Rh or Ru or a compound thereof, the mixture meltspun to form fibres which are cured to make them infusible, carbonized, and the carbon fibres activated. Activation is effected using a mixture of steam and nitrogen, and carbonization at 900 C. in a nitrogen atmosphere. In another method a carbonizable infusible polymer, suitably polyacrylonitrile, cellulose or a resol, is dissolved to form a spinning dope, the catalyst incorporated therein and the dope spun into fibres which are carbonized and activated. Alternatively the catalyst may be applied to carbonizable and infusible fibres suitably phenol resin fibres, polyacrylonitrile fibres or cellulosic fibres which are then carbonized and activated. In a further method carbonizable and infusible fibres are carbonized and activated, at least one compound of Pd, Pt, Rh or Ru incorporated in the activated carbon fibres, and the fibres subjected to a reducing treatment, e.g. with hydrogen at 100 to 500 C., or to heat-treatment at not less than 500 C. in an inert gas or in air, or to treatment With formaldehyde or hydrazine to convert at least part of the metal compound to a metal element. In gas absorption tests, a gaseous mixture consisting of 400 p.p.m. carbon monoxide, 40 p.p.m. carbon dioxide, 20% oxygen and the remainder nitrogen is passed through a column of the fibres, and all the carbon monoxide is oxidized.
