PROVISIONAL SPECIFICATION.
Improvements in Anti-induction Electric Apparatus.
We JULES CERPAUX, Electrician, PIERRE BORRE, Barrister at Law, and LÉON
MAERTENS, Gentleman, all of 24 Rue de l'Eveque, Brussels, in the Kingdom of
Belgium, do hereby declare the nature of this invention to be as follows:--
Our invention refers to a new electric anti-induction apparatus for telephonic and
telegraphic lines, and our said invention consists of two tubes of glass or other
analogous material containing an alcoholized liquid and into each of which dips two
conductor rods each terminated by a disc or washer of carbon or other equivalent
material and placed in proximity to one another at a distance apart regulated by a set
screw working one of the rods.
Between these two tubes there is a coil placed, forming communication between the
two tubes and through which coil the current passes from one of these tubes into
the other.
The current coming from the line wire is carried towards one of the conductor rods
and passes into the tube to the washer of the said rod, then traversing the alcoholized
liquid, it passes by the washer of the opposite rod, to the coil, and from thence, passes
into the lower rod of the other tube, to go from the washer into that of the second rod
of the latter tube, and passing by the washer it issues by the upper end of the upper
rod to the line wire.
When the commutator is placed so that the current passes into or through the
anti-induction apparatus, induction will be thereby destroyed. Thus when the true
current arrives at the end of the lower rod it leaps over the space left free between it
and the upper rod while the induction which is weaker than the true current, stops,
that is to say, the electric current passes to the lower ends of the conductor rods, and
in order to continue its passage the current is then compelled to pass through the
space between the ends of the two conductor rods, the true current being strong
enough to effect its passage through, whilst the induction current being feebler stops
and proceeds no further.

Improvements in Anti-induction Electric Apparatus.
We, JULES CERPAUX, Electrician, PIERRE BORRE, Barrister at Law, and LEON
MAERTENS. Gentleman, all of 24 Rue de l'Eveque, Brussels, in the Kingdom of
Belgium, do hereby declare the nature of this invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement:-
Our invention refers to anti-induction apparatus for telephonic and telegraphic lines,
and such apparatus composing our said invention consists of two tubes of glass or of
other analogous material containing an alcoholized liquid, into each of which dips two
conductor rods each terminated by a disc or washer of carbon or of other equivalent
material and placed in proximity to one another at a distance apart which may be
regulated by a suitable mechanical device such as a set screw.

page_text: Between these two tubes there is placed a relay coil which forms a communication
between the said tubes, or forms a portion of such communication, and through this
coil the current passes from one of these tubes into the other.
Our invention will be readily understood by reference to the accompanying drawing
which shews an apparatus constructed according to our invention, and drawn to two
thirds of its actual size or thereabouts.
A is a platform or base plate on which the various parts composing the apparatus
may be conveniently fixed; B is a post or terminal carrying the telegraph or other
wire, and C the line wire.
The current coming by C from the line wire is carried towards one of the conductor
rods D, and passes by this rod into the tube d to the washer d', the current then
traverses the alcoholized liquid, it passes by the washer e¹ of the opposite rod E to the.
relay coil F, and from thence passes into the lower rod G of the other tube to go from
the washer g¹ through the alcoholized liquid g to the washer h¹ and so by the rod H to
the line wire.
When the commutator is placed so that the current passes into or through the anti-
induction apparatus, induction will be thereby destroyed. Thus when the true current
arrives at the end of one of the rods it leaps over the space to the second rod while the
induction which is weaker than the true current stops, and proceeds no further.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. In anti-induction apparatus, the combination of the glass or analogous tubes
containing an alcoholized liquid, the metallic or carbon conducting rods terminating in
washers or discs of similar material or materials, and the relay coil or coils F, all
substantially as and for the purposes herein described and shewn with reference to the
accompanying drawing.
2nd. In anti-induction electric apparatus formed of tubes of insulating material and
of inetallic or carbon rods provided with washers or discs of the same material and
dipping into an alcoholized liquid contained in the said tubes, the employment of one
or more relay coils in connection and in combination with the said tubes and between
same as shewn and described.
