Abstract
Mejoras en sistemas de señales eléctricas caracterizado por una línea eléctrica y telefónica a través de la cual pasan corrientes de distintas frecuencias estando una de ls frecuencias asignada a señales medios para transmitir las frecuencias por dos vías distintas medios en la primera de las vías para atenuar igualmente todas las frecuencias medios para atenuar y si es posible eliminar la frecuencia de señales medios para rectificar estas corrientes en la salida de las vías y para obtener corrientes continuas medios para combinar los potenciales mientras se oponen entre sí para obtener de este modo un potencial que corresponda a la frecuencia de señales si existen medios para gobernar un relevador electrónico mediante el potencial resultante medios para utilizar la operación del relevador electrónico e indicar así la presencia de la frecuencia de señales.Improvements in electrical signal systems characterized by an electrical and telephone line through which currents of different frequencies pass, one of the frequencies assigned to medium signals to transmit the frequencies by two different means in the first of the ways to also attenuate all frequencies means to attenuate and if possible to eliminate the frequency of signals means to rectify these currents at the output of the tracks and to obtain continuous currents means to combine the potentials while opposing each other to obtain in this way a potential that corresponds to the frequency of signals if means exist to govern an electronic relay by the resulting potential means to utilize the operation of the electronic relay and thus indicate the presence of the frequency of signals.
