1, HERMANN HÜBENER, Doctor of Medicine, of Berlin S.W:, 18-19 Alte Jacob
Strasse, in the Empire of Germany, do hereby declare the nature of my, invention
THE MANUFACTURE OF ARTIFICIAL
for AN IMPROVED PROCESS FOR
MINERAL WATERS to be as follows:-
The object of the present invention is to produce artificial. mineral waters which
shall have all the advantages of the natural mineral waters at the same time
obviating their disadvantages as also those of the artificial waters prepared up
till now.
The natural mineral waters, of which a great quantity and variety are at present
on the market, can hardly be considered harmless beverages. Seltzer water, for
instance, one of the most popular beverages, certainly does not influence the
digestive organs.beneficially on account.of.the large amount of soda.it.contains.. But
on the other hand this water contains so much common salt that any desired degree
of thirst may be produced by taking it. This, beverage must be considered
decidedly injurious for persons suffering from fever where the amount of gastric
juice is already lessened and as proved by scientific examinations. contains a
relatively small quantity of hydrochloric acid..
Artificial mineral waters are imitations of the natural waters and besides having
their own peculiar disadvantages, hereinafter described, possess all those of the
-latter. In addition to this as the method of manufacturing such waters is imperfect
they may be undoubtedly characterised as inferior.
•
The superior kinds of artificial waters manufactured under the direction of men
of science in this branch of the industry do not differ much from the natural
waters in their chemical constituency, but rather in that the presence of atmo-
spheric air therein prevents the thorough intermixture of the carbonic acid gas-with
the water.
During the whole course of the manufacture of artificial mineral waters, the
carbonic acid gas has only been pumped into the water and then the superfluous
quantity of mixed air and gas blown off. By this means it was generally believed
that the air would be blown off with the gas. Supposing however that by
continually repeating this process the air is blown out it still. remains an uncertain
and tedious process. Since by Dalton's law it may be assumed that the carbonic
acid gas, on the water being impregnated therewith, will combine with the air
present in the water, at the end of the blowing off process the gas remaining in the
water will still be mixed with some air. For this reason an artificial water entirely
equivalent to the natural water has not yet been produced.
By the process hereinafter described, I have succeeded in obviating these dis-
advantages and producing a beverage equal to any natural mineral water and
having a better, more refreshing and more pleasant taste.
I preferably employ a mixture of phosphate of soda, sulphate of soda and.
carbonate of lime.
The lime is added to correct or improve the taste. The amount of-soda liberated
by the lime added causing the sulphate of soda to decompose, is so small that it need
not be taken into account. The sulphate of lime formed is held in solution by the
presence of the carbonic acid.
The phosphate and sulphate of soda exercise a thoroughly beneficial influence on-
the body, both having a sedative effect on the circulation, cooling and regulating
the flow of the blood.

page_text: In preparing this mineral water the solution employed and subsequently to be
impregnated with carbonic acid, should be absolutely free from air otherwise
the carbonic acid gas will combine with the air of the water, and instead of combining
with the water will simply be mechanically pressed into the same, thus escaping as
soon as the bottle is uncorked.

As distilled water regains considerable air in condensing, I preferably boil the

air. Or I can also free the solution from air by employing a vacuum.
solution is then led off through an outlet near the bottom of the boiler into an air
tight reservoir containing carbonic acid gas. The mixture is then led to the
machine where it is impregnated with carbonic acid gas at a pressure of two and a
half atmospheres, and bottled in the usual manner. Great care must be taken to
prevent the access of even the least quantity of air, during the whole process.

An Improved Process for the Manufacture of Artificial Mineral
Waters.
I, HERMANN HÜBENER, Doctor of Medicine, of 18-19 Alte Jacob Strasse,
Berlin, S.W., in the German Empire, 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 :-
The object of the present invention is to produce artificial mineral waters
which shall have all the advantages of the natural mineral waters at the same
time obviating the disadvantages of the same as also of those artificial waters
prepared up till now.
The natural mineral waters of which a great quantity and variety are at present
on the market, can hardly be considered harmless beverages. Seltzer water, for
instance, one of the most popular beverages, certainly does not influence the
digestive organs beneficially on account of the large amount of soda it contains,
but on the other hand this water contains so much common salt that any desired
degree of thirst may be produced by taking it. This beverage must be considered
decidedly injurious for persons suffering from fever, where the amount of gastric
juice is already lessened and as proved by scientific examination, contains a
relatively small quantity of hydrochloric acid.
Artificial mineral waters are imitations of the natural waters and besides having
their own peculiar disadvantages hereinafter described possess all those of the
latter. In addition to this as the method of manufacturing such waters is
imperfect they may be undoubtedly characterized as inferior.
The superior kinds of artificial waters, manufactured under the direction of men
of science in this branch of the industry, do not differ much from the natural
waters in their chemical constituency but rather in that the presence of atmo-
spheric air therein prevents the thorough intermixture of the carbonic acid gas
with the water.
During the whole course of the manufacture of artificial mineral waters, the
carbonic acid gas has only been pumped into the water and then the superfluous
quantity of mixed air and gas blown off. By this means it was generally believed
that the air would be blown off with the gas. Supposing, however, that by con-
tinually repeating this process the air is blown out, it still remains a very uncertain
and tedious method. Since by Dalton's law it may be assumed that the carbonic
acid gas, on the water being impregnated therewith, will combine with the air present
in the water, at the end of the blowing off process the gas remaining in the water

equivalent to the natural water has not yet been produced.
By the process hereinafter described I have succeeded in obviating these dis-
advantages and produced a beverage equal to any natural mineral water and having
a better, more refreshing and pleasant taste.

To 1000 grammes of water entirely freed from air
Phosphate of soda free from air

and a suitable small quantity of citrate of soda according to taste.
The lime is added to correct or improve the taste.

The amount of soda liberated
by the line added causing the sulphate of soda to decompose, is so small that it need
not be taken into account. The sulphate of lime formed is held in solution by the
presence of the carbonic acid.
The phosphate and sulphate of soda exercise a thoroughly beneficial influence on
the body both having a sedative effect on the circulation cooling and regulating the
flow of the blood.
In preparing the mineral water, the solution employed and to be impregnated
with carbonic acid should be absolutely free from air otherwise the carbonic acid gas
will combine with the air of the water and instead of combining with the water
will simply be mechanically pressed in the same thus escaping as soon as the bottle
is uncorked.
Since distilled water regains considerable air in condensing I preferably boil the
solution of the salts mentioned above in a boiler for some time in order to drive out
the air or can draw out the air by evacuation. Boiling the solution, besides
driving out the air has the very advantageous effect of thoroughly sterilising the
same, as it is well known that bacteria and micro-organisms contained in the solution
will be destroyed by the high temperature. The solution is then led off through an
outlet near the bottom of the boiler, into an air tight reservoir containing carbonic
acid gas. The mixture is then led to the machine where it is impregnated with
carbonic acid gas at a pressure of 24 atmospheres and bottled in the usual manner,
great care must be taken to prevent the access of even the least quantity of air,
during the whole process.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed I declare that what I
claim is:
1. The process of producing healthy and refreshing artificial mineral waters
better capable of retaining their carbonic acid when not under pressure consisting
in sterilising and expelling the air from a solution of phosphate of soda, sulphate
of soda, citrate of soda and carbonate of lime advantageously in distilled water, by
heating this said solution previous to charging the same with carbonic acid gas
substantially as described.
2. The process for manufacturing my improved artificial mineral water substan-
tially as herein before described.
