page_text: We, RICHARD KLEBS, Ph.D. and ISIDOR ROSENTHAL M.D. both of Königsberg,
in the Kingdom of Prussia, 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 :-
Our invention relates to improvements in artificial carbonated mineral waters.
The object of our invention is the production of an artificial carbonated mineral
water containing creosote or any of the component parts of the latter hereinafter
mentioned the said water being intended for use in treating cases of phthisis in
accordance with the successful experiments lately made by Professor Fraentzel, of
Berlin, and Professor Sommerbrodt, of Breslau, the favorable results of the said
experiments being due to the antiseptic action, upon the pathogeneous bacterii, of the
creosote or its component parts. Considerable difficulties have however been
experienced in administering the creosote or its component parts in a therapeutic
manner by reason of their bad taste and their corrosive action upon the stomach
and its membranes. To avoid said difficulties we have, after may tests, and
experiments, succeeded in transforming the creosote or its component parts so
that they are, in their new form easily digestible, of an acute action, and relatively
tasteless.
The component parts of
" creosote are, chiefly Guajacol" (C, H, O₂),
"Creosol" (C, H₁, O₂), "phenol" (that is "carbolic acid" C, H, O) "phlorol'
and "creosol."
"
We have attained these new results by producing from the creosote or its com-
ponent parts, and under addition of other substances hereinafter referred to, a
carbonated mineral water.
In carrying our said invention into practice, we proceed as follows, that is to
say, We first produce a solution of creosote in water preferably adding thereto an
alkaline earth, such as burned magnesia. The proportion of creosote contained in the
solution thus obtained, is then exactly ascertained. The said proportion of creosote
in the solution is then fixed, by adding to the solution in order to flavour the same,
ethereal oils having no medicinal properties, extracts from suitable plants, and also a
stimulant such as brandy, and a proper quantity of water.

page_text: Of the solution thus obtained having a fixed proportion of creosote, or of any of its
component parts, a proper quantity, which depends on the nature of the cases for
which the medicine is intended, is poured into a bottle of a standard size and then
transformed into an artificial carbonated mineral water by completely filling the said
bottle with pure carbonic water, the proportion of ethereal oil, creosote and brandy
being such that even after many years of rest the creosote does not part from the
carbonated water which remains unchanged and is ready for use at any time.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:-
First. The method, substantially as herein described, of producing an artificial
carbonated mineral water, said method consisting in first preparing an aqueous
solution of creosote or any of its component parts, preferably in presence of an
alkaline earth, and stating or ascertaining the proportion of creosote contained in
the said solution, then adding flavouring and stimulating ingredients and water to the
solution and thereby fixing the proportion of creosote in the solution, and finally
adding pure carbonic water to the latter so that the same is transformed into an
artificial carbonated mineral water, substantially as and for the purposes specified.
Second. An artificial carbonated mineral water containing creosote, or any of its
component parts, for the purpose specified.
