ABSTRACT:
A portable pulsed signal generator which generates a low-frequency, high-ered signal from a constant direct current, low power source is disclosed as including an inverter for driving a plurality of motors which, in turn, actuate control switches by means of cams and cam followers associated therewith. A potentiometer driven by one of said motors, in turn, effectively controls the output of a direct current amplifier, with the varying direct current output signal therefrom having the alternate half-waves thereof polarity reversed by switch controlled relays, the switch of which is timely actuated by one of the aforesaid cams, cam followers, and other switches, respectively, so as to produce a low-frequency, high-power, substantially alternating current signal. After appropriate transduction said low-frequency, high-power, substantially alternating current signal may be employed for sweeping mines.
