Title: Improvements in or relating to level control devices for signal transmission systems
IPC: H03G7/00
Filed: 1957-10-02
Abstract: 871,783. Automatic gain control. TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES. Oct. 2, 1957 [Oct. 4, 1956], No. 30852/57. Class 40(5) In an a.g.c. circuit the gain is held at its last value when the signal disappears, by disconnecting the discharge path of the condenser across which the a.g.c. voltage is developed. Equal signals are fed from transformer 4, Fig. 1 to the a.g.c. detector 9 and to an oppositely-poled diode 11 which completes the path to earth of the detector load resistor 11. Diode 11 is provided with a negative delay bias which is of smaller value than the positive delay on a.g.c. diode 9, but which is greater than the working value of the a.g.c. voltage on condenser 6: thus the normal a.g.c. voltage is substantially that produced by diode 9, but if the signal suddenly fails diode 11 is cut off and the discharge path of condenser 6 opened. A resistor of high value may be connected between condenser 6 and a point of fixed potential, so that the gain moves to a predetermined value if the signal is absent for a considerable time. Alternatively, condenser 6 may be connected via oppositely poled diodes 25, 26, Fig. 2, and resistors 20, 21 respectively to the point U 5  of fixed potential. A further pair of oppositely poled diodes 18, 19, fed with equal signals from transformer 15 and provided with equal delay biases, are so poled that upon conduction, i.e. when signal is present, the voltages produced across resistors 20, 21 cause diodes 25, 26 to cut off, allowing condenser 6 to take up the proper a.g.c. potential.

Title: Superregenerative transmitter-receivers operating in the millimetre waveband
IPC: H04B1/54
Filed: 1975-07-23
Abstract: 1493663 Millimetre waveband transceivers THOMSON-CSF 23 July 1975 [24 July 1974] 30884/75 Headings H3Q H3T and H4L In a millimetre waveband transmitter-receiver, wherein information is carried by frequency modulating the repetition rate, of millimetre frequency wavetrains, the tuning of a millimetre waveband oscillator {resonant cavity 2 and avalanche diode 3 supplied from controllable voltage supply source 24} is controlled by detecting the envelope of beat frequencies, between the repetition frequency of the wavetrains carried for transmission by the millimetre wave from the oscillator and corresponding received wavetrain frequencies, {curvature in the avalanche diode negative resistance characteristic ensuring detection}, and causing the oscillator frequency to sweep, in a search procedure, as long as the output of the envelope detector is below a given threshold. The beat frequencies appear at the output of a bandpass filter 7, the output of envelope detector 13 passing to threshold device 15 with manual setting control 16, an electronic switch being enabled as long as the threshold is not exceeded, so that pulses from clock 18 can be counted by binary counter 19, whose count passes to d/a converter 20; whose characteristics are chosen to suit the desired sweep of millimetre wavelengths; the converter controlling the supply voltage from source 24 and hence the oscillator frequency. A multi-step, substantially sawtooth frequency sweep pattern continues to be generated as long as the threshold is not exceeded. Diode 3, resonant cavity 2 and horn 1 are shared for duplex, or alternate, use. Transmitter-receiver arrangement: (i) Transmission. The amplified signal from microphone 14 controls the frequency of frequency modulable relaxation oscillator 4, power amplifier 5 providing a frequency modulated pulse train at junction 50, the millimetre wave band oscillator operating within the duration of each pulse. (ii) Receiving. The {frequency modulated} beat signal is either directly detected by a discriminator centred on the difference in the f.m. carrier frequencies, or, for duplex operation, the beat signal passes to mixer 12 also receiving the output of relaxation oscillator 4, the mixer output, centred on the carrier frequency of the received signal alone, being detected by a discriminator centred on the latter frequency. Non-interfering communication between a plurality of pairs of transmitterreceivers is possible, provided such pairs define distinct beat frequencies. Reference has been directed by the Comptroller to Specification 1,373,736.
