Process and Apparatus for the Automatic Mixing of Liquids
with Carbonic Acid.
We, OSCAR BRÜNLER of Tempelhof near Berlin Merchant and CARL GUSTAV
ROMMENHÖLLER of Rotterdam, Merchant do hereby declare the nature of said invention
for "PROCESS AND APPARATUS FOR THE AUTOMATIC MIXING OF 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 object to render superfluous the use of special driving
engines, transmissions of power or other arrangements of the like nature for mixing
or impregnating liquids with gases such as obtains in the mineral water manufacture,
and it consists of a process for the automatic impregnation of liquids with carbonic
acid and in arrangements or apparatus by means of which the process is performed.
For this purpose the liquid to be impregnated is exposed to the action of the gas
over as large as practicable a surface in the manner that the liquid is caused to fall or
pass down an inclined plane in the form of a shallow stream within a vessel charged
with compressed carbonic acid, whereupon the descent of the liquid to be impregnated
is regulated in the same measure as the liquid impregnated is withdrawn from the
apparatus.
Referring to the accompanying drawing which represents apparatus such as we use
for carrying out our invention —
Fig. 1. consists substantially of a vessel A for the liquid to be impregnated, & a
vessel B in which the mixing of the liquid with carbonic acid is effected. These two
vessels A and B are placed in communication with each other by the pipe d, so that
the compressed carbonic acid supplied through pipe a to the vessel A may pass to the
vessel B. An aperture at the bottom of the vessel A is fitted with a valve v by which it
may be opened or closed, the former only taking place when the impregnated liquid is
drawn off from the apparatus out of the bowls through pipe and valve or
cock z¹. The bowls upon its being emptied is driven upwards by the liquid collected
at the bottom, when the valve v is opened and liquid to be impregnated flows so long
over the shoot w on to the worm like or winding surface b and downwards into the
bowls until this latter is charged and by reason of its weight sinks down and closes
the valve v. Whilst the liquid passes over b it offers to the compressed gas above it

page_text: an extremely advantageous contact surface, the surface b being so designed that the
liquid upon reaching the bowls is suitably impregnated with the gas.
Fig. 2 shews a modification of the apparatus; in this case, the liquid instead of
flowing over a winding wormlike surface, flows over surfaces like b, c and further,
instead of the bowl s as shewn in Fig.1 a float s' is employed which raised by the
impregnated liquid collecting at the bottom of the vessel B closes the valve v.
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 for the automatic mixing of liquids with carbonic acid consisting in
bringing the liquid to be impregnated into contact with the gas over an extremely
large surface between the liquid and gas in the manner that the liquid in its down-
ward flow within a closed vessel charged with compressed carbonic acid is caused to
flow or fall downwards in a shallow stream, and where the liquid to be impregnated is
collected in a closed vessel in communication with and under the same pressure as the
aforesaid vessel, substantially as described and shown.
2. An apparatus for carrying out the process hereinbefore described consisting
mainly of a vessel A for receiving the liquid to be impregnated, a vessel B provided
with the surface or surfaces band with the automatic arrangement v, s. or v, s for
the delivery of the liquid to be impregnated on to the surface or surfaces b
substantially as described and shewn.
