In carrying out present improvement ,
employ circuit-controller containing two

Referring the drawings, which illustrate

charging the condenser and for discharging
it through the circuit low self-induction;
and among the means which have hereto
fore employed for this purpose was me-
25 chanical contact device which controlled both
the charging and the discharge circuit in
such manner that the condenser was alter
nately charged the former and discharged
into the latter.
This invention improvement ap

eral plan heretofore invented and practiced

ing condenser circuit possessing capacity
