    After a discussion of impulse excitation, three forms of gaps suitable for such extreme quenching are described. Braun tube oscillograms showing the operation of such gaps for various values of "inverse charge frequency" (number of secondary oscillations per primary discharge) are given. They show a remarkably regular gap-functioning over hundreds of thousands of cycles. The problems of commercial... View full abstract»

    By taking account of the variable distribution of inductance and capacity along a vertical grounded antenna, the general expression for the current at any point of the antenna is obtained. For the case of an antenna having zero current at the top and maximum current at the (unloaded) bottom, the particular solution for current and voltage distribution is obtained. View full abstract»

    The possibilities of securing tone phenomena with the a.c. resonance transformer, spark gap method, and with the high tension d.c. spark gap method, are considered. There are treated a.c. rotary spark gaps, resonance transformer effects on tone production, and the effects produced respectively by needle and spherical gaps. The results of using rotary, needle, and spherical gaps with high tension d... View full abstract»
