Abstract
Mejoras en relevador de comparación de fase que comprende una red de comparación de fase que tiene primero y segundo circuitos de entrada y un circuito de salida; un primer medidor de tiempo que tiene su entrada conectada al circuito de salida de la red comparadora y que tiene una salida accionada al final de un primer intervalo predeterminado de tiempo después del accionamiento del circuito de salida de la red comparadora, caracterizadas porque comprenden un segundo medidor de tiempo que tiene su entrada conectada con la salida del primer medidor de tiempo y que tiene una salida accionada al final de un segundo intervalo predeterminado de tiempo después del accionamiento de la salida del primer medidor de tiempo; una red de conteo que tiene su entrada conectada con la salida del primer medidor de tiempo y que tiene una salida accionada como consecuencia de un número plural de accionamientos del primer medidor de tiempo; una red de disparo de ruptores y dispositivos de conexión que interconectan la red de disparo con las salidas del segundo medidor y de la red conteo, siendo los dispositivos de conexión efectivos para accionar la red de disparo como consecuencia del accionamiento de la salida ya sea del segundo medidor de tiempo o de la red de conteo, siendo la red efectiva para accionar su circuito de salida sólo cuando la fase de las señales de impulso suministradas a los circuitos de entrada, están dentro de una relación de fase predeterminada.
