Abstract

Perfeccionamientos en los circuitos para señalizadores acústicos, eléctricos, sin contactos, caracterizados porque la señal es dada al señalizador (12) en forma de impulsos, cuya amplitud se mantiene inversamente proporcional a la de la tensión alimentada al señalizador a igualdad de prestación, en el mismo.
