PROVISIONAL SPECIFICATION.
Improved Electrical Apparatus for the Treatment of Air, Gases, .
. and Vapours.
We, Dr. AUGUSTE EUGENE BONNA, Dr. ALEXANDRE LE ROYER, and PAUL
VAN BERCHEM, Licencinte es Sciences, all of 6 Rue St. Léger Geneva, in the
Republic of Switzerland, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of apparatus intended to cause the electric
spark or effluvia to be brought into contact with air or gas or vapour for certain
chemical purposes.
Our apparatus is formed of an enlarged vessel intercalated between two tubes
through which the air, gas or vapour is caused to circulate, the said enlarged vessel
being provided with suitable electrodes arranged so as to have the electric-current
spread out almost through all the parts of the interior of the vessel.
The accompanying drawing shows in vertical central section and by way of
example two different constructions of our improved apparatus.
A Figure is.a bell or vessel of glass or other suitable material the inner walis
of which are provided with a series of metal rings F which are joined together by
means of connections f
The positive electrode D is formed of a series of metal rings d of .smaller
diameter than the rings F and joined together by means of suitable connections d'.
The negative electrode E is formed of a series of metal rings e of smaller
diameter than the rings F and joined together by means of suitable connections e
The distances between the rings F, d and e are such as to allow the electric
current which enters the apparatus at D to spread out or leap from the rings d all
around to the upper rings whence it passes along the connexions to the lower
rings F and finally leaps to the rings e and escapes by the wire E.
In the modification shown in Figure 2 the electrode D is connected to a spiral coil D¹
provided all around the inner wall of, the vessel A, and the electrode E forms the
core of an electro-magnet El which acts upon the electric effluvia entering the
apparatus through the coil D' and attracts the same all round its own surface.
The conductors F, d and e may assume the form of spiral windings instead of
rings.

We, Dr. AUGUSTE EUGÈNE BONNA, Dr. ALEXANDRE LE ROYER, and PAUL
VAN BERCHEM, Licenciate es Sciences, all of 6 Rue St. Léger Geneva, in the
Republic of Switzerland, 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 :-
The invention relates to the class of apparatus intended to cause the electric

page_text: spark or effluvia to be brought into contact with air or gas or vapour for certain
chemical purposes.
Our apparatus is formed of an enlarged vessel intercalated between two tubes
through which the air, gas or vapour is caused to circulate, the said enlarged
vessel being provided with suitable electrodes arranged so as to have the electric-
current spread out almost through all the parts of the interior of the vessel.
The accompanying drawing shows by way of example one construction of our
improved apparatus.
A is a bell or vessel of glass or other suitable material the inner walls of which
are provided with a metallic spiral D' which is connected with an electric circuit
by means of suitable connections.
The positive electrode is formed of the core E of an electro-magnet E¹. The
said core E projecting into the vessel A within the spiral D' and the coil E¹ of said
electrode being branched upon the electric circuit of which D and E form the
electrodes.
The distances between the spirals D' and the core E are such that the electric
current entering the apparatus at E spreads out from the core E to the spirals D¹
as shown by the arrows and leaves the apparatus at D.
The electro-magnet El acts upon the electric effluvia, entering the apparatus
at E, causing the same to assume a rotatory movement insuring a complete
connexion of the said electric effluvia with the gases, entering the bell or vessel A
through the tube B and leaving the same through the tube C.
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 :-
An improved electric apparatus for causing the electric effluvia to act upon a
certain volume of air, gas or vapour for certain chemical purposes, characterized by
the combination of a vessel A, having an inlet-tube B and an outlet-tube C for
the air, gas, or vapour to be treated, with a metallic spiral D' forming one of the
electrodes of an electric circuit, and with an electro-magnet E E, the core E of
which forms the other electrode of the said electric circuit, and the coil E¹ of
which is branched on the said circuit.
