COMPLETE SPECIFICATION.
Process and Apparatus for Automatically Mixing Liquids with
Carbonic Acid.
We OSCAR BRÜNLER of Tempelhof near Berlin in the German Empire, Merchant
and CARL GUSTAV ROMMENHÖLLER of Rotterdam in the Kingdom of Holland
Merchant do hereby declare the nature of said invention for
"PROCESS AND
APPARATUS FOR AUTOMATICALLY MIXING LIQUIDS WITH CARBONIC ACID" 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 obiect to render superfluous the special driving engines,
transmission of power or other arrangements of the like nature for mixing liquids
with gases such as obtains in the mineral water manufacture. The said object is
attained by the utilisation of the work which is stored up in the compressed and
mostly fluid carbonic acid.
The process which is the chief part of the present invention consists in that the
impregnation of liquid with carbonic acid is effected automatically in the measure and
according as the liquid impregnated is withdrawn, for which purpose use is made of
a jet throwing apparatus, or of an ejector by which a stream or jet of carbonic acid in
the compressed state is utilised for carrying along with it the liquid to be impreg-
nated, as well also at the same time the difference of pressure which occurs upon the
withdrawal of the impregnated liquid for mixing the gas with the liquid.
Referring to the accompanying drawing :-
Fig. 1 shews an apparatus such as is used for carrying into effect this invention.
Fig. 2 is a modification of a part of the apparatus and Fig. 3 is a detailed view.
A is a container supplied with compressed carbonic acid; B a vessel supplied with
the liquid to be impregnated; J, a jet throwing apparatus, ejector or the like which
drives the liquid to be impregnated from the vessel B through pipe c to the mixing
machine MR whence the liquid in the impregnated state passes into the vessel C to
be finally withdrawn from the apparatus through valve or cock z.
The vessel B is by means of the pipe connection 6 placed under the pressure of the
compressed carbonic acid in A, in consequence of which upon a withdrawal of
impregnated liquid at the valve gas and unimpregnated liquid will stream to the jet
apparatus J. The resulting stream caused by the lessening of the pressure in C is

page_text: hereupon utilised for the automatic thorough mixture of liquid and gas, the jet
apparatus having previously only effected an imperfect mixture, as represented in
Fig. 3 where it is shewn how the liquid and gas after both have passed from the
ejector are in an imperfectly mixed state, and how the gas bubbles are cut up or
divided by being caused to impinge against bars or resisting parts o, thus bringing
about a more intimate contact of the gas with the liquid. The thorough mixing
operation is effected in the passage of the imperfect mixture driven by the same
agency through the mixing machine. It may take place either by the imperfect
mixture being driven against bars or other resisting parts or by the rods or resisting
parts being moved in the liquid, both automatically feasible by the force of the stream
upon the withdrawal of the impregnated liquid from the apparatus.
The mixing machine shewn in Fig. 1 consists of the vessel M, turbine wheel R. and
shafts carrying several arms or bars. The turbine wheel R is fixed on the shafts and
when the imperfect mixture coming from the jet apparatus meets the wheel this latter
is, with the shafts and arms on the same, moved round and a thoroughly intimate
mixing of the liquid with the gas, effected. Arms s¹ arranged around the interior of
the vessel M may if required be employed for increasing the resistance. The mixing
machine may be modified as shewn in Fig. 2 in the sense that instead of moving
mixing arms it is fitted with fixed resisting parts such as bars or sieves past and
against which the mixture is automatically driven by the force of the stream acting
upon the withdrawal of the impregnated liquid.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim, is:
1. The process of automatically mixing liquids with carbonic acid, consisting in
drawing the liquid to be impregnated from a closed vessel under pressure by means
of compressed carbonic acid through the agency of a jet apparatus or ejector, and in
passing the same through a mixing machine in the same measure as the impregnated
liquid is withdrawn from the apparatus substantially as described and shewn.
2. The combination of the closed vessel B for the reception of the liquid to be
impregnated with jet apparatus or ejector J substantially as described and shewn.
3. The combination of the vessel B with the jet apparatus or ejector J and mixing
machine R M s, or the combination of the vessel B with the jet apparatus or ejector .
and the mixing machine indicated in Fig. 2.
