Abstract

Perfeccionamientos en circuitos de protección de cinescopio de televisión, para un aparato de deflexión de televisión en el cual la energía de deflexión vertical se deriva de señales de deflexión horizontales para integración que comprende, un dispositivo generador de supresión del haz acoplado a una fuente de señales de sincronización verticales y al cinescopio, caracterizados porque el dispositivo generador de supresión por un multivibrador monoestable, un circuito o bucle de realimentación y por tener su entrada acoplada a la fuente de señales de sincronización vertical para adoptar el estado inestable al comienzo de cada una de las señales de sincronización, acoplándose la salida del multivibrador al cinescopio para la supresión del haz durante una parte por lo menos de su estado inestable y para no entrar en supresión durante su estado estable, y medios de inhibición acoplados a la fuente de señales de deflexión horizontales y al multivibrador adopte su estado estable excepto la presencia de la señal de deflexión horizontales.
