Title: Improvements in or relating to systems of radio transmission and reception
IPC: H04B1/68
Filed: 1935-08-23
Abstract: 461,749. Wireless signalling. JOHNSTONE, D. M., and BAIRD TELEVISION, Ltd. Aug. 23, 1935, No. 23670. [Class 40 (v)] A carrier wave is transmitted in successive periods of substantially equal duration, the amplitude during any one period being constant and a function of that of the modulating signal. A control signal of the same periodicity as the carrier interruption frequency is simultaneously transmitted. At the transmitter an amplifying valve 3 fed with the modulating currents is followed by a sharply tuned circuit 5, which may be a critically regenerative valve circuit and is periodically biassed to cut-off by a pulse generator 4. The signals thus produced feed an amplifier 6 and are then radiated. A carrier is also transmitted modulated with impulses from the generator 4. At the receiver a sharply tuned circuit responsive to the signal carrier is periodically quenched by the receiver control signal which, if necessary, may be passed through a phase-shifting device. A common control-frequency signal may be radiated for several transmitters. Specification 455,298 is referred to.

Filed: 1925-03-24
Abstract: 251,843. Buchholz, M. March 24, 1925. Addition to 198,936. Transformers.-In safety devices for electrical apparatus operating in an insulating liquid of the kind described in the parent Specification, in addition to contacts operated by the formation of gases of decomposition, other contacts are provided which operate when the level of the liquid falls, e.g. through leakage. Fig. 1 shows a device which closes a circuit f on the generation of gases, and which closes this circuit and an additional circuit at i when the liquid level falls. A tube b is adapted to be connected for example in the pipe between a transformer and a rectifying vessel. A float c normally rests against an annular stop e but when gases of decomposition are produced they collect around the float and beneath the stop causing the float to descend and bridge contacts f in an indicating or cut-out circuit and allowing the gases to ascend into the cylinder a. The float c would also bridge the contacts f if the level of the liquid fell through leakages. A float g provided in the tube b is adapted to make contact at i when the liquid level falls. Fig. 2 shows a. modification having floats k, j carrying co-operating contacts which intermittently engage each other when gases are generated, and the float k carries an additional contact adapted to engage a contact beneath it when the liquid level falls.

A vacuum-moulding machine comprises vacuum moulding means, and a lifting head and heating means which are movable relative to the moulding means in such a manner that a sheet of plastics material positioned over a mould which constitutes part of the moulding means can be softened by the heating means, and that after the sheet has been heated as aforesaid and moulded, the moulded sheet can be lifted from the mould and deposited at a location remote from the moulding means by the lifting head. A sheet of thermoplastics material, e.g. polyvinyl chloride is fed from a roller device, Fig. 8 (not shown), above a table 16 where it is clamped to the side members 61 of a clamping frame 58 by hydraulic jacks 63, which frame 58 includes a heater 62 and a removable shield 64, the whole assembly being constructed to be moved into position above a main vacuum chamber 12 having sealing edges 21 and an associated mould chamber 19 which is raised to seal against the underside of the members 61. The shield 64 is then withdrawn to allow the sheet to be softened, at which stage the sheet is drawn tight against the moulds by application of vacuum. The shield 64 is reintroduced between the heater 62 and the moulded sheet, the clamps 63 released and the mould chamber and sheet lowered. Hydraulic means then operate knives on the clamping frame 58 to engage in grooves 89 in the moulds to cut longitudinally the sheets after which the frame and knives are retracted. A pick-up device 76 then moves into position above the moulded sheet, and associated knives make transverse cuts in the sheet, when a vacuum pick-up lead 79 is lowered to remove the moulded and cut sheet from the moulds 19. To facilitate removal from the heat 79, pressure can be applied in place of vacuum. The roller mechanism which feeds the sheet to the machine is controlled for rate of feed and tension of the thermoplastic sheet by a brake device.
