I called attention when | first described
this system of energy transformation,
was found in the devices necessarily
used for controlling the charges and
discharges Of the condenser.
''They We're wanting in efficiency and
reliability, and threatened to prove
decided drawback, greatly restricting
the use of the system and depriving it
of many valuable features.
For number of years l have tried
to master this difficulty. During this
time a great number of such devices
were experimental upon Many of
them promised well at first, only to
prove inadequate in the end.
Reluctantly, I came back upon an
idea on which I had worked long be-
fore. 1t was to replace the ordinary
brushes and commutator segments by
fluid contracts. I had encountered diff
ficulties then, but the intervening years
in the laboratory we're not spent in
vain, and l made Roadway.
First it was necessary to provide
for a circulation of the fluid, but fore
ing it through by pump proved itself
impractical.
Then the happy idea presented it.
self to make the pumping device an in
tegral part of the circuit interrupter,
enclosing both in a receptacle to pre-
vent oxidation.
ing the circulation, as by rotating
body of mercury, presented themselves.
Then I learned how to reduce the wear
and losses which still existed. I fear
that these Statements, indicating how
much effort was spent in these SEEM
insly insignificant details, will not con-
vey a high idea of my ability, but I con-
fess that my patience was taxed to the
utmost.
FINALLY, though had the satisfaction
of producing devices which are simple
and reliable in their operation, which
require practically no attention and
which are capable of effecting a trans
formation of considerable amounts of
energy with fair economy
THE physician will not be able to
obtain any instrument suitable to full
fill many requirements. He will be abe
ITO use in acknowledgements treatment
in most of the ways enumerated. He
will have the, facility of providing him
self with coils such as he NAV desire
to have for any particular purpose
which will give him any current or any
pressure he may wish ito obtain.
such coils will consist of but few
turns of wire, and the expense of pre-
pairing them will be quite insignificant.
THE instrument will also enable him
to generate Rontgen rays of much
greater power than obtainable with or
binary apparatus.
"A tube must be furnished by the
manufacturers which will deteriorate,
and which will allow to concentrate
larger amounts Of energy upon the
electrodes.
when this is done nothing will stand
in the way of an extensive and eff
cient application Of this beautiful dis
covery which must ultimately prove
itself of the highest value, not only at
the hands of the surgeon, but also of
the acknowledgements and, what is most
important, of the bacteriologist.
The first and simplest method of ap-
plying the currents was to connect the
body of the patient to two points of
the generator, be it a dynamo or an in
duction coil. The alternator may be one
given from five to ten thousand COM
pete vibration per second, this num-
Der being still within the limit of prac-
ticability.
