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. 85
In this case employ jar receptacle A
which preferably used also one terminal
and filled with conducting liquid, before. SerialN

benefits the improvement above described,
