Abstract

Un sistema repetidor de datos de ángulos, paso a paso que incluye medios transmisores que tienen medios de salida plurales que proporcionan tensiones de datos incrementales de conductores múltiples desfasadas indicativas de ángulo, medios receptores paso a paso cooperantes para repetir dicha información de ángulo y que tiene medios de entrada plurales correspondientes y canales plurales de tratamiento de datos para acoplar dichos medios de salida plurales respectivos a medios correspondientes de dichos medios de entrada plurales, caracterizado porque cada uno de los canales de tratamiento de datos comprende medios de circuito de disparo que responden a la presencia de un nivel de tensión de salida alto y bajo en unos primeros medios de dichos medios de salida plurales, primeros medios de diodo acoplados en serie con la salida de dichos medios de circuito de disparo, medios de amplificador acoplados a dichos primeros medios de diodo para suministrar corrientes de excitación alta o baja correspondientes a primeros medios de dichos medios de entrada plurales y que tiene medios de corriente de retorno en común con dichos medios de circuito de disparo, medios de impedancia, segundos medios de diodo que tienen un electrodo de control, estando acoplados dichos medios de impedancia y dichos segundos medios de diodo en relación de serie entre la salida de dichos medios de circuito de disparo y dichos medios de retorno de corriente, medios de impedancia preceptores que perciben la amplitud de dicha corriente de excitación para desarrollar a su través una correspondiente tensión de preceptor, y medios de circuito que acoplan dicha tensión de preceptor a dicho electrodo de control con lo cual solamente en presencia de dicha corriente de excitación alta y de una incidencia de avería que da lugar a que dicha tensión de preceptor aumente por encima de un nivel predeterminado, dichos segundos medios de diodo quedan retenidos en su estado de conducción quedando retenidos dichos medios de amplificador en su estado de no conducción y protegiendo de destrucción debido a dicha incidencia de avería a dichos medios de amplificador.
