I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool & 6, Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows :-
―
This invention has for object to enable, by the employment of the electric current
in the distillery, substances and materials to be used in the manufacture of German
yeast, which substances, owing both to their colour as well as to their odour or other
properties, have not hitherto been suitable for the production of German yeast,
besides which they only yielded a spirit of low value.
The employment of electricity for the purposes of the present invention is founded
on the development of ozone, under suitable circumstances, and on the strong
oxidising properties of the same, by means of which it can, on the one hand, be
used for bleaching certain organic substances, and for rendering them colourless or
odourless, and, on the other hand, can also serve for removing, from any liquids
bleached with sulphurous acid, the excess of this substance which is deleterious to
the fermentation, and to the development of yeast through its conversion into
sulphuric acid.
In this manner, by means of ozone, mashes, worts, extracts of nitrogenous sub-
stances, such as bran, malt, germs, vetches, lupines, ground-nuts, linseed (and other
feeding) cakes, animal refuse, as albumen, meat, flour and fish guanos, which, by
heating under strong pressure, have changed their colours, may be employed for the
production of German yeast.
Such materials as molasses and beet-root juices which, owing to their dark colour
and the strong odour which they develop on fermentation, were hitherto quite
unsuitable for producing yeast, may also be utilised in this manner, either alone or
in combination with mashes, worts and the above named extracts.
At the same
time, through the devolopment of ozone, the quality of the spirit is considerably
improved.
In order to produce a sufficient quantity of ozone for this purpose, it is preferable
to proceed in such a way as to ozonise air or oxygen by means of an ozonising
apparatus, for instance, that constructed by Siemens, and to blow this ozonised air
into the liquid which is to be bleached, and this is best performed at the temperature
of from 60 to 80 degrees centigrade, although the bleaching will take place also at
a lower temperature.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool & 6 Bank Street, Man-
chester both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer, 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 :-
This invention has for its object to enable, by the employment of the electric
current in the distillery, substances and materials to be used in the manufacture of
German yeast, which substances, owing both to their colour as well as to their
odour or other properties, have not hitherto been suitable for the production of
German yeast, besides which they only yielded a spirit of low value.
The employment of electricity for the purposes of the present invention is founded
on the development of ozone, under suitable circumstances, and on the strong
oxidising properties of the same, by means of which it can, on the one hand, be
used for bleaching certain organic substances, and for rendering them colourless or
odourless, and, on the other hand, can also serve for removing, from any liquids
bleached with sulphurous acid, the excess of this substance which is deleterious to
the fermentation, and to the development of yeast through its conversion into
sulphuric acid.
In this manner, by means of ozone, mashes, worts, extracts of nitrogenous sub-
stances, such as bran, malt-combs, vetches, lupines, ground-nuts, linseed (and other
feeding) cakes, animal refuse, as albumen, meat, flour and fish guanos, which, by
heating under strong pressure, have changed their colours, may be employed for the
production of German yeast.
Such materials, as molasses and beet-root juices which, owing to their dark colour
and the strong odour which they develop on fermentation, were hitherto quite
unsuitable for producing yeast, may also be utilised in this manner, either alone or
in combination with mashes, worts and the above named extracts. At the same
time, through the development of ozone, the quality of the spirit is considerably

into the liquid which is to be bleached, and this is best performed at the temperature
of from 60 to 80 degrees centigrade, although the bleaching will take place also at
a lower temperature.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is-
The improved process for the production of yeast and spirit by the employment
of ozonised air or oxygen consisting in the bleaching and rendering odourless,
mashes or worts, extracts or saccharine solutions in yeast and spirit manufacturing
by treating them by means of ozone or air charged with ozone.
