Kopenhagen, Denmark, Engineer.]
A Method and Apparatus for Subjecting Liquids having Substances
Suspended in them to Centrifugal Action, whereby they are
brought into Contact only with Sterilized or with other Air,
with which they are to be Saturated.
I. OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Fellow of the Institute of Patent Agents, do hereby declare
the nature of this invention to be as follows:-
In my Specification No. 86 of 1889 is described centrifugal apparatus applicable
mainly for treating worts and beer, and a method of conducting the brewing process,
so that the worts and beer are brought into contact with sterilised air only. Since
the filing of the said Specification it has been found, that this method is of great
importance in the treatment by centrifugal action and aëration of various other
fluids or semifluids, water, blood, milk, oil, yeast, wine and spirits, avoiding the
contact of atmospheric air which contains ferments or germs so that it is advisable
to treat these substances in completely closed vessels supplied exclusively with
sterilised air.
Wine and spirits should first be heated to render them capable of taking up
more air.
Any gaseous fluid which mixes readily with the liquids treated and saturates
them can be used instead of sterilised air; and the centrifugal apparatus described
in the Specification above referred to can be arranged for use in producing liquids
so saturated with air or gas as for instance, liquids containing carbonic acid gas,
such as soda water, lemonade &c.
It is often of importance to saturate water thoroughly with sterilised air in
order to effect oxidation and precipitation of the particles of iron contained therein;
also to supply the cells of an aquarium.
In separating albumen from the corpuscles in blood by means of centrifugal
action, it is also of great importance that the albunen should come in contact only
with sterilised air, when it has to be preserved for some time.
Instead of employing the centrifugal apparatus described in the Specification
above referred to a centrifugal apparatus of ordinary construction can be used for
the same purpose, but this being so arranged that the liquids to be treated are
completely cut off from contact with the atmospheric air and can absorb only
sterilised air or other gas with which they are to be saturated.
The accompanying drawing is a vertical section of a centrifugal machine arranged
according to my invention.
On the shaft B is fixed the rotating drum A, which is enclosed within the air
tight casing C.
The sterilised air or other gas is admitted through the tube D, and the liquid to
be treated is admitted through E. The liquid after being operated on is discharged
through the pipe F, which is bent outside the vessel C so as to form a liquid seal, so
that it is impossible for the atmospheric air, to come in contact with the fluid in the
centrifugal apparatus.

.
I, OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Fellow of the Institute of Patent Agents, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:—
In my Specification No. 86 of 1889 is described centrifugal apparatus applicable
mainly for treating worts and beer, and a method of conducting the brewing
process. so that the worts and beer are brought into contact with sterilised air
only. Since the filing of the said Specification it has been found, that this method
is of great importance in the treatment by centrifugal action and aëration of various
other fluids or semifluids, water, blood, milk, oil, yeast, wine and spirits, avoiding
the contact of atmospheric air which contains ferments or germs so that it is
advisable to treat these substances in completely closed vessels supplied exclusively
with sterilised air.
Wine and spirits should first be heated to render them capable of taking up
more air.
Any gaseous fluid which mixes readily with the liquids treated and saturates
them can be used instead of sterilised air; and the centrifugal apparatus described
in the Specification above referred to is arranged for use in producing liquids so
saturated with air or gas as for instance, liquids containing carbonic acid gas, such
as soda water, lemonade &c.
It is often of importance to saturate water thoroughly with sterilised air in
order to effect oxidation and precipitation of the particles of iron contained therein;
also to supply the cells of an aquarium.
In separating albumen from the corpuscles in blood by means of centrifugal
action, it is also of great importance that the albumen should come in contact only
with sterilised air, when it has to be preserved for some time.
Instead of employing the centrifugal apparatus described in the Specification
above referred to a centrifugal apparatus of ordinary construction can be used for
the same purpose, but this being so arranged that the liquids to be treated are
completely cut off from contact with the atmospheric air and can absorb only
sterilised air or other gas with which they are to be saturated.
The drawing accompanying my Provisional Specification is a vertical section of
a centrifugal machine arranged according to my present invention.
On the shaft B is fixed the rotating drum A, which is enclosed within the air tight
casing C.
The sterilised air or other gas is admitted through the tube D, and the liquid to
be treated is admitted through E. The liquid after being operated on is discharged
through the pipe F, which is bent outside the vessel C so as to form a liquid seal,
so that it is impossible for the atmospheric air, to come in contact with the fluid in
the centrifugal apparatus.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
1. Subjecting liquids, such for instance as blood, milk, water, oils, yeast, wines
and spirits, to centrifugal action and aëration with sterilised air and without contact
with atmospheric air, in apparatus such as is described in the Specification No. 86
of 1889.

page_text: 2. Saturating liquids with gases by treating them in centrifugal apparatus from
which atmospheric air is completely excluded.
3. The centrifugal machine with its air tight casing its supply pipes and its
discharge pipe with scal, substantially as described with reference to the accom-
panying drawing.
