Abstract

IMPROVEMENTS INTRODUCED IN THE OBJECT OF THE PATENT No. 247,190, by ELECTROAUTOMÂșTICO DEPARTMENT FOR REMOTE DIRECTION BY SOUND, essentially characterized by that they consist of interposing between the microphone fed by the battery and the other pole of the same, a capacitor and a resistor variable, constituting the amplifying element by several transistors and extending the resistance connected to said amplifier with other components that act in combination with the first as voltage dividers, arranging the amplifier composed of said transistors connected to a relay that consists of a flexible sheet linked to the positive pole of the battery, said relay also comprising two contacts, one of which is located at the end of a coil supplying the magnetic field of a selector, and the other end of the coil being connected to the coil. negative pole of the battery, with whose contact arrangement each time it is rec When an acoustic signal is heard in the microphone, the circuit selector moves step by step, actuating the motor organ, with the particularity that said selector or the relay itself can act on a conventional inverter to govern different movements.
