Abstract

Sistema transmisor de mensajes que comprende, en combinación, una estación transmisora dotada de un transmisor, un cierto número de producciones de frecuencias, procedimientos selectivos de comunicación que interconectan dichos elementos de producción de frecuencias con el transmisor mismo para modular la producción obtenida incluyendo a su vez los procedimientos de conmutación medios para seleccionar combinaciones de frecuencias que correspondan a los mensajes que han de transmitirse y una estación receptora dotada de un receptor, procedimientos de filtraje conectados a dicho receptor para separar el conjunto de frecuencias transmisoras, procedimientos de reproducción de los mensajes y sistemas en conexión con dichos filtros para controlar de modo automático dichos procedimientos de reproducción de los mensajes que resulten por las combinaciones de frecuencias recibidas y reproducción de los mensajes recibidos en el transmisor.Message transmission system comprising, in combination, a transmitting station equipped with a transmitter, a certain number of frequency productions, selective communication procedures that interconnect said frequency production elements with the transmitter itself to modulate the production obtained including its instead of the switching procedures means to select combinations of frequencies that correspond to the messages to be transmitted and a receiving station equipped with a receiver, filtering procedures connected to said receiver to separate the set of transmitting frequencies, procedures for the reproduction of messages and systems in connection with said filters to automatically control said procedures of reproduction of the messages resulting from the combinations of frequencies received and reproduction of the messages received at the transmitter.
