Abstract

1,125,904. Transistor pulse circuits. MULLARD Ltd. 21 Sept., 1965, No. 40184/65. Heading H3T. The whole of the subject-matter of this Specification is contained in Specification 1,125,902, but the claims relate to a circuit for repetitively charging and discharging an inductor with means for varying the duration of the charging pulse in dependence upon the supply voltage so as to maintain the pulse amplitude constant, the invention being described in relation to the mono-stable transistor multivibrator described with reference to Figs. 5, 6 and 7 of that application. The whole of the subject-matter of this Specification is contained in Specification 1,125,902, but the claims relate to the means for varying the width of voltage pulses applied to an inductance in dependence upon the supply voltage, in order to maintain constant the peak voltage of output pulses derived from circuit. The invention is described with reference to Figs. 5, 6 and 7 of that Specification.
