To all whom concern:
Be known that Nikola Tesla, citi

The device hereinafter described espe

use with existing circuits carrying’direct cur

The circuit, including the motor rela- go
tively high self-induction, and this property
is imparted the coils the motor, or,
when these are not sufficient, bythe addition
of suitable choking-coils, that each

charging the condenser, which may therefore
be small and inexpensive.
