The adjourned High Court case . . . WIRELESS TELEGRAPH TRANSMITTER A transmitting system in which tuned primary and charging circuits energise an exciting circuit, which in turn delivers unidirectional impulses or kicks to an electrostatically-coupled radiator clr- cuit. The exciting circuit is characterised in being pro- vided with more two condensers, one of which is common to the radiator circuit. The unidirectional impulses are obtained from the exciting circuit by the use of an air-blast gap working with a pressure of ??-100lb. per square inch. In operation the constants of the exciting circuit are so adjusted that it has no distinctive fre- quency of its own in order that the radiator may freely oscillate in its own time period.
