to all whom it may concern
be it known that i , nikola tesla , a citizen of manhattan , in the city ,county ,and
state of new york , have invented certain new and useful improvements in means for increasing the intensity of electrical oscillations , of which the following is a specification, referencebeing had to the drawings accompanying and forming part of the same .
in many scientific and practical uses of electrical impulses or oscillation as , for example, in systems of transmittingintelligence to distant points it is of great importance to intensify as much as possible the current impulses or vibrations which are produced in the circuits of the transmitting and receiving instrumentsparticularly of the latter it is well known that when electrical impulses are impressed upon a circuit adapted to oscillate freely the intensity of the oscillation developed inthe same is dependenton the magnitude of its physical constants and the relation of the periods of the impressed and of the oscillation
for the attainment of the best result it is necessary that the periods of theimpressed should be the same as thet of the free oscillation, under which conditions the intensity of the latter is
greatest and chiefly dependent the inductance and resistance of the circuit beingdirectly proportionate to the former and inversely to the latter. in order, therefore, to intensify the impulses or oscillations excited in the circuit in other words to produce the greatest rise ofcurrent or electrical pressure in the same it is desirable to make its inductance as large and its resistance as small as practicable. llaving this end in view i have
devised and used conductors of...
