In the practical application method
I usually proceed follows: any two

This the case when, for example, each no

invention into practice.
To overcome these and other limitations

method accomplishing these ends.
50 The method, briefly stated, consists pro
ducing arbitrarily-varied intermittent dis
turbances effects, transmitting such dis
turbances effects through the natural me
dia distant receiving-station, utilizing
55 energy derived from such disturbances ef
fects the receiving-station charge con

that without further provision not enough

of energy imposes narrow restrictions re
