IPC: H03K3/284
Filed: 1956-06-22
Abstract: 859,320. Transistor pulse circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 6, 1957 [June 22, 1956], No. 19485/56. Class 40(6) In a transistor pulse generator of the kind in which the output pulse duration is determined by a time-constant circuit comprising a resistor connecting the emitter of a transistor to its supply terminal and a capacitor connected to the emitter, the second terminal of the capacitor is connected to a second transistor, to determine the initial potential at the second terminal of the capacitor. In the quiescent state of the circuit shown transistor TA is conducting, TB non- conducting and TC conducting, the potential V2 at the collector of TC determining the potential at the left hand terminal of a timing capacitor C. An input pulse applied to the base of transistor TA will diminish in collector current and by regenerative action through TB transistor TA will be rapidly cut off and TB will become fully conducting so that the potential at the left hand terminal of the capacitor will fall to the collector potential of TB (-12v). The capacitor will now charge at a rate determined by resistor Rl until transistor TA commences to conduct, whereupon by regenerative action the circuit returns to its initial condition. The pulse amplitude and duration may be varied by varying the potentials of the collectors of transistors TB and TC and a constant current transistor may be connected in series with the emitter of transistor TA. The transistor TA may be held on a linear part of its characteristic during the quiescent condition by choice of resistor R2 or by means of a diode D.

Title: Improvements in or relating to two-way communication systems
IPC: H04B3/20
Filed: 1934-07-02
Abstract: 440,572. Two - way transmission. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and MURPHY, F. M. G., Orchard Lodge, London Road, Chelmsford. July 2, 1934, No. 19512. [Class 40 (iv)] In a terminal arrangement connecting a two-way path to separate transmitting and receiving paths, each of the three paths includes a frequency changer and filter arranged so that (1) received signals after being changed in frequency, cannot pass into the transmitting path but after a further frequency change in the two-way path will pass through the filter in that path, and (2) outgoing signals from the two-way path after subjection to frequency change in that path are brought to the required transmitting frequency by the frequency changer in the transmitting path. The use of a hybrid coil is thus avoided. The transmitted and received signals need not be of the same frequency. The invention is described as applied to a telephone subscriber's line L connected over a four-wire circuit OE, IE to a wireless transmitter and receiver, the frequency changers being fed from a common oscillator P although this is not essential. A signal of frequency S outgoing from the subscriber passes filter Fl and is transformed at changer Ml into PŒS, the upper side band passing F2 and being changed at M2 into Sand 2PŒS of which S passes F4 into the transmitting path. Signals of frequency S incoming over IE pass F3 and are changed to PŒS at M3, the lower side band P-S being passed by F5 and changed at M1 to S and 2P-S of which S passes filter F1 into subscriber's line. If the frequencies of the local oscillations supplied at M2 and M3 are P+L and P-L respectively, the transmitted and received frequencies will be inverted (L-S). The frequency changer at M1 is a two-way device and a suitable circuit is shown in Fig. 2. The local oscillations P are applied to a transformer Z3 having a secondary which interconnects the centre taps of windings of transformers Z1, Z2 the ends of the windings being connected over rectifiers D1, D2. There is considerable suppression of the local oscillations in the output to F1 or X as the case may be.
