PROVISIONAL SPECIFICATION.
Improvements in the Application of an Electric Current in the
Boiling or Evaporating of Solutions or Liquids.
I, EMILE LOUIS CONSTANT SCHIFF of Delft in the Kingdom of Holland,
Engineer do hereby declare the nature of this invention to be as follows:-
The present invention refers to improvements in the boiling or evaporating of
solutions or liquids by the application of an electric current and more especially to
the manufacture of carbonic acid gas of the character such as that referred to in
the Specifications of Letters Patent granted to E. Luhmann, respectively dated
1st June 1891 No. 9171, the 6th June 1891 No. 9646, the 15th June 1891 No. 10158,
where potash ley is used, and has for its object to accelerate and further the boiling
of such potash ley.
In order to obtain this object, I make use of an electric current, of suitable
capacity, and energy, but which should be of comparatively low tension, as other-
wise the water of the solution would become decomposed, hydrogen and oxygen
accumulating on the anode and cathode.
This electric current I apply in a similar way to that used in electro depositing
of metals, and I apply same in the copper in which it is intended to boil the potash
ley; the result being that such ley is raised to boiling point much more rapidly,
and that throughout the process of boiling, a great economy of time and fuel is
realised.
I do not limit myself to employing the means above referred to for reducing the
boiling point by means of an electric current to potash ley, but can apply the
process to similar brines, solutions, etcetera: which may require evaporating or
concentrating, such as, for instance :-concentrating brine in manufacture of
salt, concentrating sulphuric acid, concentrating sugar by introduction in the
vacuuni pan.

I EMILE LOUIS CONSTANT SCHIFF of Delft in the Kingdom of Holland,
Engineer 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 present invention refers to improvements in the boiling or evaporating of
solutions or liquids by the application of an electric current and more especially to
the manufacture of carbonic acid gas of the character such as that referred to in
the Specifications of Letters Patent granted to E. Luhmann respectively dated

of such potash ley.

capacity, and energy, but which should be of comparatively low tension, as other-
wise the water of the solution would become decomposed, hydrogen and oxygen

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The application of an electric current in aid of the boiling, or evaporation of
solutions, or liquids, in the manufacture of carbonic acid gas, where potash is used;
and also for aiding other similar boiling or evaporating operations substantially as
and for the purposes set forth.
