Title: Process of and apparatus for producing spliceless annular bodies
IPC: B29D30/52
Filed: 1963-07-31
Abstract: 988,837. Moulding seamless annular articles. UNITED STATES RUBBER CO. July 31, 1963 [Nov. 2, 1962], No. 30275/63. Heading B5A. In a method of moulding an annular article, e.g. a tyre tread, of a plastic material, an annular mould is filled with the material, while maintaining a relative rotation between the radially inner and outer boundaries of the annular mould. In operation stock S, Fig. 1, is compressed and fed by a screw 28 of decreasing pitch along a barrel 17 and round spacers 22, located between plates 19 and 20, into an annular mould defined by a member 23 and a member 47 having flanges 47a and 47b. The member 47 is a tapered fit within and is keyed to a member 43 which carries a gear 48 driven through gearing by a motor 56, the member 43 being part of an axially movable cage structure 37. The shallow screw flights 23a on the stationary mould member 23 in conjunction with the rotation of the mould member 47 exert an additional forward force on the stock to advance it and fill the mould. The appearance of flash around the mould flange 47a indicates the filling is complete and the screw 28 is stopped while the mould member 47 continues to rotate. The hydraulic cylinder 57 is then actuated to move the cage structure 37, 38, 39, 43 along the sleeve 24 so that the mould member 47 moves away from the member 23, the flange 47b severing the tread T from the stock S and the screw flights 23a smoothing the inner surface of the tread. The mould 47 is removed and the article stripped therefrom manually or automatically. The mould member 47 may be of split or unitary construction and latches may be provided to hold the mould in the sleeve during extrusion. In another embodiment the outer rotating mould part, its driving motor and gearing are not supported on the sleeve 24 but are mounted in a framework which is carried on rollers movable along floor rails. In a further example, Fig. 8, the inner mould part 88 comprises an extension of the feeding screw 87 and the mould cavity is fed via one or more passages 89. In still another embodiment shown in Fig. 9, the mould members 122, which are axially split and have cylindrical outer surfaces, are mounted on the extrusion barrel 111 and indexed by an hydraulic actuator 123, the continuous action of the screw 115 filling the moulds as they pass through the sleeve 117, the portion of the screw 116 which may be several moulds in length smoothing the inside of the article and imparting a forward component of motion to the mould by virtue of the shallow screw flights 116a. The ejected filled outer mould is received by an automatic transfer mechanism 125, the article removed and the mould parts 122 are returned to the position shown in 122t. The temperature of the stock S may be controlled in any of the embodiments by circulating fluid through the extrusion screw in ducts as shown by the ducts 120 and 121 in Fig. 9.

Title: Frequency modulation receivers, particularly for multiplex reception
IPC: H04J1/20
Filed: 1954-10-26
Abstract: 762,726. Multiplex signalling; frequency modulation. DAY, J. R. Oct. 26, 1954 [Jan. 21, 1954], No. 30854/54. Class 40(5) A multiplex frequency modulation receiver for receiving without crosstalk a carrier frequency modulated by a signal and one or more modulated subcarriers comprises (1) a selective portion operating in a range of signal input such that valve input admittances remain substantially constant (2) a plurality of non-linear amplitude range compressor stages of broad bandwidth compared with that of the selective portion, each becoming overloaded (3) a symmetrical amplitude limiter. The compressor stages may be a grounded grid triode 31 (Fig. 7) of low anode voltage, or a pentode with control grid input. In each case the output or input may further be shunted by an asymmetric conductor 41a or a pair of oppositely oriented conductors. The symmetrical limiter may be an interstage biased pair of series connected oneway conductors 42, 43 whose junction at mean potential - E/2 stabilized by high resistances 44, 45 cannot vary above earth or below -E voltage. The selective stages may include an inter-stage pair of damped resonant circuits 74-76 and 78-80 coupled by a capacitor 81 to provide just sufficient bandwidth and with a step-down capacitative voltage divider 78-79 to the input of the following stage so that variations in valve input admitance accompanying autogain control produce a correspondingly reduced effect on the tuning of the resonant circuits, and less distortion. Or a stepdown transformer may replace the voltage divider 78, 79. Specification 757,776 is referred to.

Title: Improvements in or relating to business machines to be controlled by perforated record cards
IPC: G06K19/04
Filed: 1946-10-16
Abstract: 595,294. Statistical apparatus. REMINGTON RAND, Inc. Oct. 16, 1946, No. 30860. Convention date, Nov. 9, 1945. [Class 106 (i) Card analysing mechanism comprises a card chamber and means including a reciprocable pin box for sensing a record card in the chamber, the pin box having sensing pins, one for each card data position, disposed in horizontal rows and vertical columns, the centres for successive pins in consecutive data positions of a horizontal row being substantially equi-distant from opposite sides of the horizontal median line for the row and disposed on the respective median lines of the vertical columns in which the pins are located. The mechanism is designed for the record cards described in Specification 595,292, which is referred to, and also for known 80-column slotted cards. Cards are fed from a magazine 40, Fig. 12, by a picker 77 and are passed to the sensing chamber 44, Fig. 13, by feed rollers 39. The leading edge of the card is arrested by a block 21 on the stop bar 22 while the sensing pins 15, Fig. 14, which are staggered as shown, are thrust upwardly by an eccentric 48 in the usual manner to set up the data in the upper pin box 52. Where cards carrying a second set of data in the spaces between the normal rows are being dealt with, a manual control 92, Fig. 12, is set in the full-line position. This prevents the complete removal of the card stop after the first analysing operation. The stop control cam 68 has a fall 90 allowing a follower arm 69 to rock clockwise and, through linkage 70, 72, 71, 73, lift the stop bar 22, but an adjustable stop 93, brought into position by the control 92, prevents the complete removal of the stop 22, the skid rolls 76 merely moving the card forward under the block 21 and against the bar 22. The feeding of a further card is prevented by a latch 83 which withholds the feeding mechanism from co-operation with its actuating cam 78. After the second reading of the intermediate data, a high portion on a cam 88 rocks a belt-crank 84 moving the member 87 to the left so that the stop 93 is rocked clear to allow normal lifting of the card stop 22, and the latch 83 is rocked clear to allow card feeding to be resumed. When 80-column slotted cards or cards without data in the intermediate rows are being analysed, the control 92 is latched in the dotted position of Fig. 12, in which position the latch 83 is held clear of the feeding mechanism and the stop 93 is out of the path of the member 71 of the card stop mechanism.

Abstract: 604,333. Metal-working presses. HERCULES ELECTRIC & MANUFACTURING CO., Inc. Nov. 19, 1945, No. 31038. Convention date, Nov. 18, 1944. [Class 83 (iv)] [Also in Group XXIII] A metal-working machine having a frame and co-operating fixed and movable dies, is provided with an elongated gauge bar to position the work, the gauge bar being adjustably clamped to the frame and electromagnetic means associated with the gauge bar to hold metal against the bar during the operation of the machine. Angular bending.-In one example the movable die 3, Fig. 1, of a bending-machine is reciprocated against a stationary die or former 2 by a drive mechanism 4 operated through a clutch 5 controlled by a foot pedal 7 through link rod 6. A gauge bar 8 adjustably secured by clamps 8a positions the work 11 and is magnetized by solenoids 9 which are vertically adjustable on pillars 10. The magnetizing current is controlled by a limit switch 37 having a crank 37a connected to the link mechanism 6a so that magnetizing current is supplied when the head 3 is at the top of its stroke and until the head has made its down-stroke thereafter the switch operates to cut off the current as the head returns so that the work may be removed. The solenoids are connected in parallel across a D.C. supply which may be drawn from an A.C. source transformed and rectified and the current is controlled by a rheostat. A manually-operated switch is provided to disconnect the solenoid during non- working or in the case of emergency and the limit switch is operative in a separate circuit to supply holding current to a contactor according to the position of the head. Shearing; punching.-In. another example, a shearing machine, Fig. 3, has solenoids associated with a gauge bar 14 adjustably supported by C clamps 14a on angle brackets 15a and the cutter head 16 moves down between the angle supports to sever the work 12. Additional holding members 17 contact the work ahead of the shear blade. In a punching machine, the operation is substantially the same as described with reference to Fig. 1, but the gauge bar may be adjustable on a block on the machine frame and clamped by screws. The solenoids may be incorporated in the framework of a machine.
