PROVISIONAL SPECIFICATION.
Improvements in Tanks for Containing Hydrochloric Acid.
I, THOMAS DAVID OWEN of The Poplars, Seabank Road, New Brighton, in the
County of Chester, Chemist do hereby declare the nature of this invention to be as
follows:-
The object is to provide tanks for containing hydrochloric acid for storage and
transit which shall be durable and impervious to the acid.
For the above purpose I construct tanks of an outer and inner shell of wood or
other suitable material the space between the two shells being filled with a new
composition of matter consisting of sulphur ground pyrites and sand or like
material. The composition is run into the space between the shells in a molten
condition.
Under a modification the acid resisting composition is combined with a
strengthening backing of timber or suitable material.
Dated this Twenty-second day of November 1892.

COMPLETE SPECIFICATION.
Improvements in Tanks for Containing Hydrochloric Acid.
I THOMAS DAVID OWEN of The Poplars, Seabank Road, New Brighton, in the
County of Chester, Chemist 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 main object is to provide for containing hydrochloric acid for manufacture,
storage, or transit, tanks, chambers, cells, towers, or the like which shall be durable
and impervious; such tanks, chambers, cells, towers, or the like being also
applicable for use in electrolytic deposition or decomposition, or for containing
acids, liquids, or gases incapable of acting on or injuring the said tanks or
the like.
For the above purpose I construct the tanks or the like of an inner and outer
shell of wood or other suitable material, the space between the two shells being
filled with a new composition of matter consisting of about equal parts by weight of
a mixture of sulphur (sometimes called brimstone) ground pyrites and sand or like
material. The said composition or mixture is heated and run in a molten condition
into the space between the shells.
Under a modification the acid resisting or inert composition is combined with a
strengthening backing of timber or suitable material such as say slate vulcanite or
metal.
In order that my invention may be readily understood and carried into practice
I have appended a sheet of explanatory drawings where Fig. 1 is a section of a
tank or the like in which a a' represents the sheets of wood or other-material with
the impervious and inert filling 6 between, so as to prevent leakage or flow of
currents; whilst Fig. 2 shows a similar tank or the like in which the backing a is
faced with the impervious and inert composition b.

page_text: 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 :-
First. The combination of sulphur, pyrites and sand or like material in about
equal parts for the manufacture of tanks for the purpose set forth.
Second. The combination of a facing and backing with a composition filling,
substantially as and for the purpose set forth.
Third. The combination of a backing with a composition facing, substantially as
and for the purpose set forth.
