35 Considering the conditions necessary for
the attainment these results, there will
be found, the essential elements the
system, the supply-circuit, from which the
periodic impulses are obtained, and what

prising the circuit high self-induction for
charging the condenser and the circuit of
low self-induction into which the condenser
discharges and which itself may constitute

devices for utilizing the current, maybe
inductively related secondary circuit
whichconstitutes the working circuit proper.
To this system combination the inven
