J T 1 1 To all whom it may concern:- D Be it known that I, Nikola Tesla, a citizen of the United States, residing at New York, in the County and State of New York, have invented certain new and useful

114 V circuit controller containing two terminals, or sets of terminals, movable with respect to each other into and out of proximity, and I provide means whereby the intervals between the periods of

T keyed or clamped to the shaft C. The plate is formed with segmental extensions corresponding in number to the These segwaves of current which the generator delivers. ments are preferably cut away

116 او کے A, in this figure, represents any source of alternating current, the potential of which is raised by a transformer of which a is the primary and b the secondary. The ends of the secondary

J 3 pulses. The potential of these impulses may be raised by a secondary T, which consti tutes the source of current for the working circuit, or that containing the devices R for utilizing the current

118 pulses, and a circuit controiler for effecting the charging and discharge of said condenser, composed of condu ctors movable into and out of proximity with each other, whereby a spark may be
