摘要： A simplified moving target detector consists of a doppler type equipment comprising a transistorized microwave source feeding a diode frequency multiplier. The same diode acts as a mixer for the reflected wave. The diode is of the variable capacitance type connected to suitable stripline stubs and feeds a low frequency output filter tuned in the doppler shift range.

摘要： An array is made of elemental radiators with an adjustable aperture controlled by a magnetizing field established within a magnetic section of the radiator. The broadening of the radiation pattern resulting from large amplitude scanning is compensated through aperture control of the individual radiators patterns in the array by means of the magnetizing field within said radiator.

摘要： An opto-electronic relay comprising an electroluminescent diode fed from unipolar or bipolar telegraph signals and a phototransistor converting the light radiated by the electroluminescent diode into relayed electric signals. Protection means are provided against overload of said diode by too strong input signals. Distortion correction means are also provided for improving the waveform of the relayed signals. The protection means include the series connection of a resistor with said diode and at least one silicon diode and a transistor shunting said diodes, while the distortion correction means include a series R.C. circuit shunting said electroluminescent and protection diodes.

摘要： A time division binary-coded data transmission system using two parallel and juxtaposed transmission lines, with a number of sending and receiving stations distributed along said lines and coupled to both of them. The first line transmits synchronization frames supplied by a central station, and the second one the information. The system is characterized in that at each sending station, the information signals transmitted by the second line are derived from the synchronization signals transmitted by the first, by means of a coupling circuit modulating the latter signals according to the coding conditions of the data to be transmitted, without altering the essential features of their waveshape. Thanks to this arrangement, the total lengths of line through which synchronization and coded data signals are transmitted are the same, and the thus preserved similarity of their waveshapes allows correct demodulation of the latter by simple comparison with the former.

摘要： Device for transmitting signaling data signals of low frequency in a multichannel carrier current system. Signaling carrier currents which may have or not the same frequency as the channel carrier currents are modulated by the signalling data signals in half-wave diode modulators, the diodes being controlled by the signalling carrier currents which have an amplitude substantially larger than the signaling data signals. The modulators are connected in parallel to an amplifier with large bandwidth and low input impedance through matching serial resistors. The number of channels of the system is reduced in order not to need individual pass-band filters associated with the modulators.
