Filed: 1920-08-24
Abstract: 172,593. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 24, 1920. Vacuum tubes.-A thermionic valve or other discharge tube for use in wireless transmitting systems has means for setting up a magnetic field of a magnitude near that at which the field produces a decrease in the current passing through the valve, and a control grid for varying the electrostatic fields between the electrodes. In one arrangement, Fig. 2, a winding 19 around the tube produces a magnetic field parallel with an incandescent filament 8 and an anode 17, the current being controlled by a helical grid 12. The anode is connected through one winding of an aerial transformer 23, and a battery 25 with the cathode, and is coupled with the grid through a variable condenser 29. The grid-cathode circuit includes an inductance 28. The capacity and inductance are turned so as to cause the valve to oscillate. The winding 19 is in series with a battery 38 and inductances 39, 40, the strength of the magnetic field being such that a small increase causes a large decrease in the amplitude of the oscillations. A telephone transmitting circuit, comprising a microphone 42, a battery 43, an inductance 44, and condensers 45, 46 of large capacity, is connected with the winding 19 so as to modulate the oscillations produced by the valve. In a modification for use as a wireless telegraph transmitter, the winding 19 is connected in series with a battery and a signalling key, the production of oscillations being stopped when the circuit through the winding is closed by the key. In another arrangement, Fig. 3, oscillations are produced by the action of the magnetic field of the winding 19 on the current in the valve, and the oscillations are modulated by varying the potential of the grid 12. The winding 19 is in series with one winding of an aerial transformer 53, a variable condenser 57, and one winding of a transformer 54, the other winding of which is shunted by a variable condenser 58, and is connected with the anode 17, and through a battery 59 with the cathode 8. By tuning the anode-cathode circuit and the circuit of the winding 19, the valve may be made to produce oscillations, which may be modulated by a microphone 60 varying the potential of the grid through a transformer 62. Specifications 130,400 and 167,561 are referred to.

Title: Improvements in or relating to a blocking device for channel receiving elements in pulse modulated multiplex communication systems
IPC: H04J3/00
Filed: 1953-09-04
Abstract: 726,634. Multiplex pulse signalling; automatic noise suppression. PINET, A. E. Sept. 4, 1953 [Oct. 3, 1952], No. 24578/53. Class 40 (5). Relates to means for blocking the receiver channel circuits in a multiplex pulse communication system when the incoming pulse train ceases, or when excessive background noise appears. In the embodiment described, the incoming four-channel train of position-modulated pulses at terminal 3 is applied to the blocking circuit 6, the sync. pulse selector 5 and a circuit 4, which converts the pulses into duration - modulated pulses. The sync. pulse is applied to a delay-line distributer 14, the tappings 23 ... 26 of which provide gate pulses for the channel selectors 8, 18, 28, 38, respectively, which are also fed with the output of circuit 4. The durationmodulated channel outputs from circuits 8, 18, 28, 38 are applied to the final demodulators 10 20, 30, 40 respectively, each of which has an intelligence signal output 11, 21, 31, 41 and a signalling signal output 12, 22, 32, 42, respectively. Each channel circuit comprises a pentode 19 to the suppressor grid 29 of which are applied the negative-going signal pulses, the longer positive-going gate pulses being applied to the control grid 27. The output pulses at the anode 33 are therefore the duration-modulated portions of the gate pulses which occur when the signal pulses have terminated. In normal operation the pulses applied to valve 35 in the blocking circuit 6 cause grid-current to flow to develop a large negative potential at the unearthed end of resistor 34. In opposition to this is a small positive potential on resistance 45 due to the rectified output of a circuit 39, in the anode circuit of valve 35, and tuned to a frequency of which the pulse spectrum contains no high level component. The resultant potential is negative and is applied to the grid of a valve 48 to prevent the operation of the anodecircuit relay 50. If the transmitter fails and no pulses are applied to valve 35, the current in resistances 34, 45 drops to zero, valve 48 conducts and relay 50 operates to connect a blocking battery 16 to the control grids of all the channel selector valves 19. If the radio circuits of a receiver supplying pulses to the point 3 fail, the rise in background noise at the receiver output produces approximately equal and opposite potentials from the resistances 34, 45 so that valve 48 is conducting to operate relay 50.
