Abstract

Intrinsic safety selection procedure for certain recurrence frequency signals, according to which any pulse signal that reaches one of the two input terminals of an intrinsically safe logic and pulse circuit, shifts the threshold of an amplifier operational and is not transmitted to the other input terminal of said logic circuit and more than if it occurs during the period of time when the voltage of a capacitor put under load immediately after the preceding signal is between the two levels of tilt said amplifier.
