    Abstract: A circuit for correcting geometrical distortions in reproducing signals on a screen of a cathode-ray tube in a display monitor. A line-frequency correction current having line deflection frequency is coupled into the vertical deflection unit which serves for deflecting vertically electron beams in the cathode-ray tube. A circuit which provides horizontal deflection current is connected to the primary winding of a differential transformer. The differential transformer has a secondary winding connected to the circuit which supplies vertical deflection current. The distortion is reflected by a cathode-ray tube which has a substantially flat picture screen, in which horizontal lines to be displayed form in angle with a horizontal reference grid.

    Abstract: A television receiver with a utility line-separated end and a controlled, line-separating, switched external power supply at the utility line end. Horizontal and vertical deflection currents are generated by horizontal and vertical output stages, and each of the two output stages are connected to a driving stage for the purpose of triggering the respective output stage. A modulator supplies a triggering signal to the driving stage and controls line separation. A horizontal frequency control signal and a vertical frequency control signal are generated and applied to horizontal and vertical sawtooth signal generators. The vertical output stage has one input connected to the horizontal sawtooth signal generator, and a second input connected to the vertical sawtooth signal generator through an error amplifier for vertical deflection of the end of the power supply connected to the utility line. The power supply is synchronized with oscillators for horizontal and vertical deflection, and is connected at the utility line-separated end.

    Abstract: A method and a device for controlling at least one operating-dynamics variable of a vehicle in closed loop are discussed. In particular, the at least one operating-dynamics variable includes a variable describing the yaw rate of the vehicle. The device includes arrangements which are used for determining whether an actuation of a parking brake contained in the vehicle exists above a predefined value for the vehicular speed. If such an actuation of the parking brake exists, then no braking interventions and/or no engine interventions, to be implemented along the lines of the closed-loop control of the at least one operating-dynamics variable, are carried out. The device makes it possible to execute an escape turn with a vehicle equipped with a device for the closed-loop control of an operating-dynamics variable.

    Abstract: A television receiver providing a stable image whether or not a composite color signal is present, in which a transmitter-recognition processes the television synchronization signals of the composite color signal. A character generator displays alphanumeric as well as graphic characters. The deflection generators and the character generator are operative with TV signals as well as characters that are alphanumeric as well as graphic. The deflection generators and the character generator are driven by control signals. An oscillator controls the deflection generators, and a phase comparator operates in the presence of synchronization signals to synchronize the oscillator. The phase comparator receives no signals from the input terminal when no synchronization signals are present, so that the oscillator oscillates at a fixed preadjustable frequency to provide a stable image.

    Abstract: A method for improving the controllability of motor vehicles during braking wherein desired slip values are determined and adjusted with the aid of a wheel slip controller. According to the method, the following are measured: the yaw rate .psi., the steering angle .delta., the wheel speeds V.sub.Ri, the inlet pressure P.sub.inlet or wheel brake pressure P.sub.i, and, if required, the engine speed and the throttle valve angle. The following variables are estimated using the measured values: the longitudinal vehicle speed V.sub.X, the longitudinal vehicle acceleration V.sub.X, the wheel slip values .lambda..sub.i, the braking forces F.sub.Bi, the tire forces F.sub.Ri, and the transverse speed V.sub.Y. Desired slip values .lambda..sub.i * are then determined from these measured and estimated variables with the aid of a simple vehicle model and supplied to the slip controller to control the vehicle wheel brake pressure.
