Title: Improvements in or relating to radio and like modulated carrier wave tunable receivers
IPC: H03J1/04
Filed: 1935-09-07
Abstract: 462,328. Valve receiving circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and O'NEILL, R. F. Sept. 7, 1935, No. 24969. [Class 40 (v)] The tuning-indicator or automatic fine-tuning means of a wireless receiver is operated by the output from one diagonal of a reactance bridge, the other diagonal of which is fed from a carrier frequency stage of the receiver, the bridge being in balance when the received frequency band is coincident with the predetermined pass band of the appropriate amplifier while any departure from tune causes the bridge to be unbalanced. The anode circuit of the intermediate frequency amplifier 3, coupling two band-pass I.F. stages 1, 2, comprises a bridge, two opposite arms of which comprise tuned circuits 11, 8 tuned respectively 3 k.c. above and below the I.F., the other arms being constituted by the reactances 10, 9, 12, 13. The output is taken across the diagonal 14, 15, rectified at 16 and applied to a vapour or gasdischarge tube 20 which glows when the bridge is unbalanced. The bridge may be increased in sensitivity by changing over the arms 10, 9 and 8. The output from 14, 15 may also be applied to a moving-slot type of station-name indicator, in which case the glow-discharge tube such as a neon tube may be mounted behind the slot and move therewith ; or the indicator may be a cathode-ray tube, the spot intensity of which is varied by the output from the bridge. Or again, the output may be applied to control tuning automatically by varying the grid bias of a tuning-valve varying the frequency-determining circuit of the local oscillator by Miller effect as described in Specification 445,543. The invention is also applicable to " straight " receivers, but in such case the tuning elements of circuits 8, 11 must be variable and are preferably ganged with the tuning of the receiver.

Title: Improvements in or relating to tire shaping machines
IPC: B29D30/36
Filed: 1931-09-12
Abstract: 384,378. Moulding wheel tyres. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Goodyear Tire & Rubber Co.; Akron, Ohio, U.S.A.) Sept. 12, 1931, No. 25642. [Class 87 (ii).] Wheel tyres are shaped by vacuum applied to the exterior of a drum-shaped blank, and by progressively inserting within the blank an air bag. A casing 17 carries a series of rods 28 which are simultaneously vertically adjustable by screw and chain gearing 32 actuated by a hand-crank. The rods carry at their upper ends a plate 13 making an airtight joint with the wall 11 of a vacuum chamber which may be exhausted by way of a pipe 14. The upper wall of the vacuum chamber consists of an annular plate 12, hinged at 18 and counterweighted at 20. The rods 28 also carry a curved cylinder 36 having an external ledge 44 to support the drum-shaped blank. A cylinder 46 pivoted at 48 and having arms 45 and a piston-rod 91, receives an air bag between the arms 45 when the piston-rod is retracted and is then rocked about its pivot in order to elongate the air bag and carry it into the curved cylinder 36. The cover 12 is locked in the closed position by a handle 19 pivoted at 18 and engaging a locking latch 24. The downward movement of the cylinder 46 is effected by a fluid-operated piston 52, rod 51, and link 49, fluid pressure being supplied by way of valve 70 controlled by a pedal 68. After closure of the cover 12, the handle 19 is moved into locking position, thereby actuating linkage 80, 76, 73 to operate the valve 70 and supply fluid pressure through pipe 61 to the cylinder 55. The cylinder 46 is thereby swung upwardly to introduce the elongated air bag progressively into the tyre, guiding faces 85 being provided on the cover 12 to render this action smooth. The link 49 has a projection 98 which actuates a valve lever 95 when the cylinder 46 is in its uppermost position and fluid pressure is thereby admitted by way of a pipe 94 to the rear end of the cylinder to thrust the piston-rod 91 outwardly and thus move the air bag into continuous contact with the tyre. The piston-rod 91 carries a shoe with hinged segments 101, 102, Fig. 5, to distribute the thrust on the air bag. According to a modification, the cylinder 37a, Fig. 6, for containing the air bag, is straight and the movement of the piston-rod 91 is controlled by contact of the rocking cylinder 46a with a valve lever 118. Specification 364,010 is referred to.
