PROVISIONAL SPECIFICATION left by Francois Brignoles at the Office
of the Commissioners of Patents, with his Petition, on the 30th August
1858. A communication.
I, FRANCOIS BRIGNOLES, of 58, Torrington Square, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR THE DISINFECTION AND RECTIFICATION OF BAD-TASTED
ALCOHOLS, BY THE SEPARATION OF THE ESSENTIAL OILS FROM THE ALCOHOLIC
EXHALATIONS," (a communication.) to be as follows:-
This operation is accomplished by condensing the alcoholic exhalations at
different degrees of temperature, and in separate tubes surrounded by water,
the temperature of each being marked by degrees. For this purpose I
establish in like ordinary way a sheet-iron boiler C, which receives the mass
of the liquid. At the bottom of this boiler is placed a pipe D, which receives
the vapour pressed down by the tube B, and which comes direct from
the generator A. The boiler C is surmounted by a column composed of
12 movable pieces, and enclosing 24 pans V. On the cone-shaped top of
the column is a stopper; through this opening water is introduced for
cleansing the apparatus. The alcohol vapours pass through the 24 pans and
through the tube F into the coiled pipe No. 1. A cold water reservoir W

municate directly with the generating boiler A, by means of the tube S and
the taps X, X, X, X, also by the plunging pipes, which allow the introduction
of the vapours or exhalations into the water which surrounds the coiled pipes.
By these means the temperature of the vat No. 1 may be maintained at a
certain degree; No. 2 at 10 degrees less; No. 3, lower still; No. 4, as cold
as possible. The alcoholic vapours entering the vat No. 1 are very partially
condensed, that is to say, the essential oils only which they contain, and which
pass through the tube B into the bottom of the pan 8. By this operation the
oils are in a great measure sent back into the boiler C, by the descending
tube y, or they may be accumulated in the syphons Z, and taken out at the
taps a, a, a. The alcoholic vapours which issue from the bottom of the
coiled pipe into the tube B, reascend by the pipe T into the second coiled
pipe, where the same operation is repeated, and thus also in the third, only
the temperature of the vat No. 2 is maintained at a certain degree, that of
the third at another temperature. On arriving at the bottom of the third
coiled pipe, the essential oil is completely exhausted, and the exhalations of
pure alcohol ascend by the tube O, to be condensed in cold water, passing
from thence by the tube Q into the cask. Care must be taken to place in
the boiler C a given quantity of quicklime with the quantity of alcohol about
to be rectified and disinfected. The apparatus can very well work with
3 coiled pipes; the 4th has been added by reason of the great quantity of
dregs met with in alcohols extracted from madder, and to avoid having to
pass through the operation a second time, the coiled pipe No. 4 has been
added, and is found to economise much time, fuel, and work.
