ELECTRICAL CONDENSER. such in

My present invention, while based upon

To all whom concern:
Be known that ikola Tesla, citizen
of the United States, residing New York,
in the county and State New York, have
5 invented certain new and useful Improve-
ments Electrical Condensers, which the
following specification, reference being-
had the drawings accompanying and form
ing part the same,
io has heretofore been announced and dem
onstrated that, under ordinary condi
tions, the efficiencyof electrical condenser
is greatly increased the exclusion air or
gaseous matter general from the dielectric. 95
the surface the electrolyte conducting
liquid poured quantity oil for the
purpose above stated.
In the accompanying drawings, annexed
in illustration the manner which im
provement maybe carried into practice,
Figure view, partly vertical section,
50 condenserconstructed accordance with
the invention.
According present invention em
ploy electrolyte, or, general, conduct
ing liquid lieu solid, the material
for the armatures the condenser, under
30 conditions more fully hereinafter described,
whereby air gas will practically pre
vented from exercising upon the condenser
or the more active portions the same the
detrimental effects present such devices as
35 heretofore made. Such condensers are es
pecially advantageous when used with cir
cuits great rates electrical vibration be
cause the high conducting capacity such
fluids for currents this character. There
40 is, however, general advantage derived
from the fact that the conducting fluids have
a high specific heat, that the temperature
remains constant, condition many cases
highly advantageous and not met with in
45 condensers ordinary construction.
