Abstract: 1,236,758. Applying tread to tyre casings. AMF Inc. 27 Sept., 1968 [12 Oct., 1967], No. 45993/68. Heading B7C. Apparatus for applying tread to a tyre casing comprises rotating table 11 carrying at opposite ends hubs 12 supporting tyre casings 10, building station 13, comprising arm 14 carrying tread applying and stitching assembly 22 mounted on rotating table 34, and sensing device 54 for gauging tread thickness, the apparatus being controlled by program card 18 containing detents 37. In operation, casing 10 is locked in position Fig. 3. Sensor 54 is moved into contact with the casing, determines the correct winding radius for assembly 13 and is retracted. Button 56 is operated to start the program, whereupon table 34 slides along guides 28 so that assembly 22 contacts casing 10. The extruding device (not shown) is now started, and strip 17 is applied and stitched to the casing, rotated by motor 47, until it has been rotated through about 300 degrees when it actuates switch 49. At this point the casing is stopped and assembly 22 is moved by motor 33 across the casing to begin another stitching cycle in a position determined by program card 18. This cycle of operations is repeated after every 360 degree rotation of the casing until the tread pattern is completed, when table 11 is rotated through 180 degrees to bring a new casing into building station 13 and enable the retreaded tyre to be replaced by another casing.

Title: Force commutated controlled rectifier circuits
IPC: H02M7/515
Filed: 1974-06-10
Abstract: 1471142 Commutating thyristors S K GOSWAMI 10 June 1974 46006/76 Divided out of 1471141 Heading H3T [Also in Division H2] In a force-commutated controlled rectifier circuit, a controlled rectifier 8 is turned off by producing a voltage pulse across an inductor 11a connected in series with the controlled rectifier 8, the commutation circuit being in the form of a loop formed when a commutating capacitor 22 is periodically connected across the inductor 11a, the voltage induced across the inductor during the reset period of the commutation circuit being reduced by selectively connecting the capacitor 22 across a larger number of turns during the reset period and across a smaller number of turns during the turn off period. As shown in Fig. 2, the controlled rectifier 8 forms part of a three-phase inverter utilizing thyristors 4 ... 9 and inverse diodes 12 ... 17. To turn off, e.g. thyristor 8, commutating thyristor 26 is turned on so as to discharge commutating capacitor 22 via diode 24 through the lower part of inductor 11a so that a higher reverse voltage is induced across the whole of 11a and also across 11b which is inductively coupled to 11a. This action turns off thyristor 8 so that the commutating current is diverted to path d-e-a. Subsequently, the voltage across capacitor 22 reverses, so that diode 24 is turned off and diode 25 turned on thus applying a lower voltage to the whole of the inductor 11a. In Fig. 8, the D.C. supply to the commutating capacitor 22 is derived from a bridge of thyristors having a centre-tapped output provided by capacitors 36 and 37. The D.C. supply to the inverter proper is connected to a mid point of inductors 10 and 11. In Fig. 15 the tapped inductors are connected in the inverse diode circuit and the tap-selecting diodes are replaced by thyristors 49 ... 51. In Fig. 9 (not shown) diode 25 is connected intermediate two sections of inductor 11a (Fig. 2).

Title: Improvements in or relating to clutches

Abstract: 1,033,668. Friction clutches. AXEL WICKMAN TRANSMISSIONS Ltd. Nov. 22, 1963 [Dec. 5, 1962], No. 46027/62. Heading F2C. In a centrifugal friction clutch for motor vehicles wherein weighted levers 18 pivoted on a driving disc 11 centrifugally urge friction shoes 15 into engagement with a driven drum 13, the movement of the levers 18 is so opposed that clutch disengagement occurs at a speed considerably lower than that of clutch engagement. The weighted levers act on the shoes through springs 20 the reaction of which, when the levers are inoperative, is taken by the heads of bolts 22 screwed into the shoes. The disc 11 is engine-driven and may be the flywheel. As shown, friction pads 24 on carriers 27 sliding on the weighted lovers are urged by springs 28 into engagement with cam surfaces on parts 26 which are secured to the disc 11 and have stops 30 at their outer ends to limit outward movement of the levers. Springs 31 reacting on the parts 26 act to return the shoes and counteract the tendency for centrifugal shoe movement whilst the weighted levers are inoperative. The cam surfaces on the parts 26 are shaped to produce a progressively increasing frictional force opposing outward, clutch engaging, movement of the weighted levers to increase the speed range over which engagement is completed. On engine speed reduction the pads 24 and cam surfaces oppose the springs 20, clutch disengagement occurring when the spring return force is balanced by the centrifugal force on the weighted levers plus the frictional force on the pads 24. The speed range over which disengagement is completed is reduced since the coefficient of friction at the pads decreases directly lever movement commences. In Fig. 4 (not shown), the friction pads are mounted directly on the weighted levers, the cam-surfaced parts being pivoted and spring urged towards the pads.

Abstract: 1,085,806. Photo-electric control of photographic printing. MEDICAL & ELECTRICAL INSTRUMENTATION CO. Ltd. Nov. 14, 1964, No. 46457/64. Heading G1A. [Also in Division G2] A device for exposure control comprises a photo-sensitive device which in a first switch position is connected in a bridge circuit with a variable impedance. The bridge is balanced by adjusting the variable impedance which is then used in a second switch position to control length of time a photographic printing lamp is on. The bridge circuit comprising the resistors R 1 , R 2  and the photo-conductive cell P. C. C. is balanced by adjusting R 1  manually or by a servosystem until the magic eye V 2  shows balance. Switch S 1  is then changed to the position shown to connect R 1  into the timer circuit. Exposure is initiated by a push button S2 which discharges the capacitor C to cut-off VIB. Relay REL makes when deenergized to light the printing lamp L. After a time determined by resistor R 1 , VIB conducts again to terminate the exposure. The apparatus is calibrated by making a test strip from a normal negative to determine the required exposure therefor and the resistor R 4  is adjusted until the timer provides the exposure. Film speed adjustment is by means of the potentiometer R 2 .
