to secure the best action the receiving-circuit

as before; but this instance will un

of conductor only one-half that used the
former case.
In the followingdetailed description shall
65 confine myself explanation that
method and apparatus only which have
found the most practical and effectual;
but obviously invention its broad fea

appliances which have devised and shall 70
here describe. 85
A great variety electrical and other de
vices more less suitable for the purpose of
detecting and utilizing feeble actions are now
well known scientific men and artisans and
need not all enumerated here.obtained connecting the two
conducting plates terminals above referred
to permanently with the poles battery.
Again, another contrivance capable be
ing utilized detecting feeble electrical ef- 115
febts consists two conducting plates ter
minals which have, preferably, wires some
length attached them and are bridged by
a mass minute particles metal other
conducting material. Normally these par- 120
tides lying loose not connect the metal
plates; bnt under the influence elec
trical disturbance produced distance,
evidently owing electrostatic attraction,
they are pressed firmly against each other, 125
thus establishing good electrical connection
between the two terminals. .
40 Again, this instance only one the ter
minals the receiving-circuit connected
to the ground, the other terminal being insu
lated, the adjustment synchronism with
the source will require that tinder otherwise

that which would used both the termi
nals connected pr, generally, the circuit
be the form 'cipsed loop coil, Ob
viously also the latter case the relative po-
50 sition the receiving and transmitting cir
cuits importance, whereas the circuit
be the former kind—that is, open—the
relative position the circuits is, rule,
of little consequence.
Still another modified device, which may 130
be said embody the features both the
former, . When electrical dis
turbance reaches circuit arrangeďánd
adjusted, additional strain put upon the
insulating-film, which gives way and allows o
the passage current which can util
ized operate any form circuit-controlling
apparatus.
Another way carry out invention is
to direct the currents discharges high-
frequency machine condenser through a
15 circuit one terminal which connected
directly, inductively with the ground and
the other body, preferably large sur
face and elevation. this case the
circuit the moving body similarly ar-

duction electrostatic induction are pro
duced and the same object attained. This change of
state may made use number ways
for the above purpose.613.
55 Finally, may avail myself, carrying out
my invention, electrical oscillations which
do not follow any particular condupting-path,
but propagate straight lines through space,
of rays, waves, pulses, disturbancesof any
60 kind capable bringing, the mechanism of
the moving body into action from distance

eitherby passingthrough the conducting-path

Still another way pass the currents
simply through the ground connecting
35 both the terminals the source high-fre
quency currents earth different and re
mote points and utilize the currents spread

In any event—that say, whichever of
the above similar plans may adopt—and
particularly when the influence exerted from
a distance upon the receiving-circuit too 75

iary sensitive relays or, generally speaking,

myself merely the electrical the most

to those which, while not the most sensitive,
are perhaps more readily available from the

ing them, may state that contrivance may

as lightning-arrester connection with
