Abstract: An arrangement in radar equipment for locking the frequency of a controllable local oscillator includes a sweep generator (10) which supplies a periodic linear control voltage to the local oscillator (3), a microwave generator (1) which generates a transmitter signal, the generator and the local oscillator each being connected via a multiplier (2, 4) to a mixer (5) in order to provide an intermediate frequency signal of the equipment, and a phase-locked loop (6, 7, 8, 9) for locking the local oscillator signal to the transmitter signal. The arrangement further includes a first selective circuit (11) including a low-pass filter in order to give an output signal if the frequency of the signal obtained from the mixer lies within a certain low frequency range compared with the intermediate frequency, a second selective circuit (12) including a band-pass filter in order to give an output signal if the frequency of the signal obtained from the mixer assumes a value in a range about the intermediate frequency, a first and a second detector (13, 14) for detecting respectively the said output signals, and logic circuitry (16) connected to the first detector and to the second detector and to the sweep generator to provide a stop signal for the sweep generator during a time interval which corresponds to a period of the linear control voltage only if an output signal is obtained from the second detector after an output signal from the first detector is obtained. <IMAGE>

Abstract: So that only a minimum number of transmission channels and test devices are required in a system for transmitting information for remotely controlling a signal box from a central control station, the outputs of in each case two processing units (VE1, VE2; VE3, VE4) which operate in parallel are connected both to the inputs of an AND element (UG) and to the inputs of an OR element (OG). Reports and commands which are critical for safety are tapped off at the output of the AND element and only appear when both processing units arrive at the same result whilst reports which are not critical for safety can be tapped off at the output of the OR element and also appear if for example a processing unit switches off as the result of a test. <IMAGE>

Abstract: Intensity regulator, especially a light regulator which can be adapted to the regulation of the light intensity of both compensated and uncompensated illuminators connected to the alternating-current mains. The regulator comprises one or more switch elements (S1, S2) disposed in a circuit between the mains and an illuminator (L) as well as a control logic circuit (4) for the switch element or elements, said circuit upon the intensity regulation breaking the supply current at least once on each half-cycle when current has been conducted from the O-moment of a half-cycle to the moment according to a set value. On one hand, a problem is the elimination of current peaks produced by voltage differences at a switch-on moment and, on the other hand, the arrangement of a control for the switch elements. To overcome the problem, the switch element (S1) is a double-switch two-way switch element connected in series with a load (L) and controlled on each half-cycle to break the current only from the mains towards the load but to permit the current flow in the opposite direction. The other two-way switch element (S2) is coupled parallel to load (L) and controlled on each half-cycle to block the current flow in the direction of the mains voltage but to permit the oppositely directed current flow therethrough. In order to determine the current breaking moment of the switches of the first switch element (S1), the control logic circuit is provided with an integrator, a mains voltage O-moment sensor and reference voltage setting means, whereby from the O-moment of the mains voltage, with the integrated voltage reaching a set reference voltage, the integrator provides a control data to a comparator logic for breaking the current of switch element (S1) in said direction.

Abstract: A final bridge stage for a receiver audio amplifier, which can be monolithically integrated, consists of two pairs of complementary bipolar transistors. The collectors of the transistors of each of the transistor pairs are connected together to form two terminals to which a transducer is connected. The transistor emitters of NPN type and PNP type transistors are respectively connected to the negative pole and, through a constant current generator, to the positive pole of a supply voltage generator. The constant current generator consists of a small resistor to which a constant voltage is applied by means of a suitable circuit. The bases of the bridge transistors are connected to the signal source by means of suitable circuits. The signal source controls similar transistors in phase opposition, while at the same time controlling the complementary transistors in phase opposition.
