Containing Alcohol.
A communication from G. R. BESSER, of 47, Georgenstrasse, Berlin, in the Empire
of Germany, Manufacturer.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:
-
This invention relates to improvements in that class of apparatus for use in
treating fluids containing alcohol in which a cooling coil and electrodes are
employed, such for instance as that described in the prior Patent No. 7813 of 1895.
Practical experiments show that if the quantity of oxygen and the molecular
vibrations be correctly selected and proportioned, it is possible by means of an
alternating current and according to the process described in the patent referred
to to remove the slightest traces of fusel oil so that not only the alcohol fluid
treated has a different taste but it becomes absolutely free from fusel oil. The
correct selection of the quantity of oxygen to be supplied presents no difficulties as
the process can be conducted as is well known so that the liquid is at first
saturated with oxygen and then the process conducted as described in the patent
referred to.
By the action of electricity the impregnated oxygen is caused to combine with
the alcohol the oxygen therefore disappearing so to say gradually and if a sample
taken shows that there are still traces of fusel oil or that the liquid is capable of
further improvement, then the process of impregnating and electrifying is continued
or repeated. But it is more difficult to determine the proper amount of the elec-
trical treatment as the cooling of the fluid has to be increased with the increased
electrical action.
The cooling coil shown in the drawing accompanying the Specification of Patent
No. 7813 of 1895 has for its chief function to maintain the alcohol or other liquid
to be treated at a uniformly low temperature while the electricity supplied serves
to produce molecular vibrations; but unfortunately the electricity at the same time
generates heat therefore the cooling actions must be increased or the cooling
surface in the iron cylinder must be increased the greater the quantity of elec-
tricity supplied that is to say the greater the surface of the electrodes. As the
increase of the surface of the electrodes thus necessitates a greater cooling surface
it was found to be difficult to arrange in the receptacle a cooling coil and the elec-
trodes of proper relative dimensions and at the same time not to render the
receptacle too unwieldy.
This drawback is avoided in the present invention by utilising the cooling coil
tself as one electrode the other one being constituted by the receptacle itself.
l'hus a proportional increase of the surface of the electrodes with the increase of
he cooling coil is automatically obtained and the possibility of the one part inter-
ering with the other is avoided.

page_text: The new apparatus differs from that of the prior patent referred to chiefly by
the electrodes being omitted while the cooling coil is of correspondingly larger
diameter and active surface. One pole of the source of alternating current of
electricity is suitably attached to the wall of the receptacle by screwing soldering
or otherwise the other wire being directly connected to the cooling coil. A further
difference is that the cooling coil is introduced into the receptacle through a guide
sleeve or socket by which the coil is electrically insulated from the receptacle.
The cooling coil as well as the inner cylinder are preferably coated with a layer
or plating of suitable metal which would not affect the tasto of the liquid to be
treated. Generally tin is sufficient, but for finer products such as cognac etc., a
coating of silver is preferable,

Improvements in Apparatus for Treating or Maturing Fluids
Containing Alcohol.
A communication from G. R. BESSER, of 47, Georgenstrasse, Berlin, in the Empire
of Germany, Manufacturer.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention relates to improvements in that class of apparatus for use in
treating fluids containing alcohol in which a cooling coil and electrodes are
employed euch for instance as that described in the prior Patent No. 7813, of 1895.
Practical experiments show that, if the quantity of oxygen and the molecular
vibrations be correctly selected and proportioned, it is possible by means of
alternating current and according to the process described in the patent referred
to, to remove the slightest traces of fusel oil so that not only the alcoholic fluid
treated has a different taste, but it becomes absolutely free from fusel oil. The
correct selection of the quantity of oxygen to be supplied presents no difficulties, as
the process can be conducted, as is well known, so that the liquid is at first
saturated with oxygen and then the process conducted as described in the patent
referred to.
By the action of electricity the impregnated oxygen is caused to combine with
the alcohol, the oxygen therefore disappearing, so to say, gradually and if a sample
taken shows that there are still traces of fusel oil or that the liquid is capable of
further improvement, then the process of impregnating and submitting to electric
treatment is continued or repeated. But it is more difficult to determine the
proper amount of the electrical treatment, as the cooling of the fluid has to be
increased with the increased electrical action.
The cooling coil, shown in the drawing accompanying the Specification of Patent
No. 7813 of 1895 has for its chief function to maintain the alcohol or other liquid
to be treated at a uniformly low temperature while the electricity supplied serves
to produce molecular vibrations; but unfortunately the electricity at the same time
produces heat, therefore the cooling action must be increased or the cooling surface
in the cylinder C must be increased, the greater the quantity of electricity supplied,
that is to say the greater the surface of the electrodes. As the increase of the sur-

page_text: face of the electricity thus necessitates a greater cooling surface it was found to be
difficult to arrange in the receptacle a cooling coil and the electrodes of proper
relative dimensions and at the same time not to render the receptacle too unwieldy.
This drawback is avoided in the present invention by utilising the cooling coil
itself as one electrode, the other electrode being constituted by the receptacle C
itself. Thus a proportional increase of the surface of the electrodes with the
increase of the cooling coil is automatically obtained and the possibility of the one
part interfering with the other is avoided.
An apparatus for the application of this process is illustrated in the accompanying
drawing.
The new apparatus differs from that of the prior patent referred to chiefly by the
special electrodes being omitted, while the cooling coil b is of correspondingly
larger diameter and active surface. One pole e¹ of the source of alternating current
of electricity is suitably attached to the wall of tho receptacle C by screwing,
soldering, or otherwise, the other wire being connected to the cooling coil b. A
further difference is that the cooling coil b enters the receptacle C through a guide-
sleeve or socket by means of which the coil is electrically insulated from the
receptacle.
The cooling coil as well as the inner cylinder C are preferably coated with a layer
or plating of suitable metal which would not affect the taste of the liquid to be
treated. Generally tin is sufficient; but for finer products such as cognac etc. a
coating of silver is preferable.
Having now particularly described and ascertained the nature of this said
invention as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is :-
-
In apparatus for treating alcoholic fluids of the character described in the
Specification of British Patent No. 7813 of 1895 the employment of the cooling coil
as one electrode and the receptacle C insulated from said coil as the other electrode
of the alternating current of electricity substantially as and for the purpose
described.
