Title: Binary decoding and indicating system
Inventor: RICHARDSON JOHN BERNARD
Filed: 1961-11-24
Abstract: 950,993. Electric selective signalling. PYE Ltd. Nov. 7, 1962 [Nov. 24, 1961], No. 42132/61. Heading G4H. A circuit for marking one of a number of outputs in accordance with a binary input comprises a plurality of electronic switches V1. . . V7 one associated with each output, means whereby only one switch can remain conducting at any one time, means for applying the successive bits of a binary input word specifying one output successively to the trigger electrodes of all those switches representing outputs whose binary equivalents require a digit in that place, and means for priming said switches so that the switch which remains finally conducting after the reception of all the bits is the one associated with the required output. In the Figure, three input bits specifying one output are applied serially to a gate circuit which routes them to terminals B1,B2,B4 respectively, and routes pilot pulses,which may occur before each, to a terminal B0. The first pilot pulse triggers an extra switch V0 which has been previously primed, thereby priming switches V1, V2, V4 whose trigger electrodes are connected to the cathode of switch V0. The priming voltage on switch V0 is removed after reception of the first pilot pulse so that subsequent pilot pulses have no effect. The terminals B1,B2,B4 are connected respectively to the trigger electrodes of switches V1; V2 and V3; V4. . .V7. Switches V3 and V5; V6; V7 are primed by switches V1,V2,V3 respectively, if and when these are triggered. A switch is triggered on reception of a "ONE" bit from the appropriate terminal B1, B2 or B4 if it has been previously primed. If pilot pulses are not used, the switch V0 may be triggered by a pulse preceding the application of the binary input to the switches. Alternatively, the switch V0 could be dispensed with and the initial priming voltage applied direct to the trigger electrodes of switches V1, V2, V4 and removed on application of the first input bit. The switches V0... V7 may be cold-cathode gas triodes as shown, or triggered transistors. The switches V1...V7 are marked with the decimal numbers 1... 7 respectively. In the case of triodes, the numbers may be mounted on the triode envelopes or on a display panel through which the triodes are visible. When the switches V1... V7 are transistors, indicating lamps replace the cathode load resistors R2 shown. Output terminals OP0... OP7 are also provided. By using more switches, longer binary words (e.g. four bit words) may be decoded. The circuit may be used in communication systems, e.g. telemetry.

Title: Improvements in or relating to loudspeaking telephone apparatus
IPC: H04M9/08
Filed: 1959-12-14
Abstract: 928,597. Two-way transmission. WESTERN ELECTRIC CO. Inc. Dec. 14, 1959 [Dec. 29, 1958], No. 42417/59. Class 40 (4). A loud-speaking telephone apparatus has, in its incoming and outgoing channels, attenuation networks varied in opposite directions by a control current obtained by rectifying the outgoing speech currents and passing the rectified output to the attenuation networks via a threshold device. As shown, a transmit channel comprising a microphone 16, amplifiers 17, 28, and an attenuator network 18, and a receive channel comprising a loud-speaker 45, amplifier 44 and an attenuating network 33 are connected via a hybrid 12 to line 11. Networks 18 and 33 are normally of moderately high and moderately low attenuation respectively. Speech on the microphone 16 is amplified and rectified to provide a positive potential on condenser 84, which when it exceeds a threshold value imposed by a Zener diode 38 causes a control current to flow through the networks 18, 33 causing the former to conduct and blocking the latter. Incoming speech, however, is rectified at 53 and switches transistor 56 into its conducting condition to maintain condenser 84 discharged and so keep the outgoing path blocked. In the quiescent condition a standing control current is provided via resistor 100 which is effective to switch a small amount of loss out of the network 18 and a somewhat larger amount of loss into the network 33. The incoming speech must overcome this loss before the transistor 56 can be made conducting, but when this occurs the standing control current is diverted via diode 38 and the transistor 56, so that networks 33, 18 become fully open and closed respectively. An additional standing current may be introduced from the manually controllable resistor 92 via rectifier 91 to act to reduce the volume of the incoming speech should this be high. This effect may be enhanced by a ganged potentiometer 31 in the input to the receive channel. The networks 18, 33 are designed so that a given control current causes more attenuation to be switched into the receive channel than is switched out of the transmit channel. A neon lamp 75 is arranged to glow when the control current is of such strength as to make the transmit circuit operative. The balance network 13 of the hybrid may be controllable by the line current to adjust its impedance in accordance with the length of line.
