Improvements in the Treatment of certain Corrosive or Poisonous
Liquids to Render them Capable of being Transported, Stored, or
used with Less Danger than hitherto.
We ISAAC SHIMWELL MCDOUGALL and JAMES THOMAS MCDOUGALL®
both of 10 Mark Lane in the City of London Manufacturing Chemists do
hereby declare the nature of this invention to be as follows:-
Our invention relates to the treatment of corrosive or poisonous liquids solutions
or extracts viz.:-sulphuric acid, hydrochloric acid, solutions of metallic salts (such
as those of zinc, copper, lead or iron) and tobacco extract whereby they are
rendered into a solid or semi-solid or friable condition.
This is effected according to our invention by means of an infusorial earth (such
as kieselguhr) which possesses great power of absorption. We mix the liquid
solution or extract with the infusorial earth in such quantities or proportions that
the infusorial earth absorbs the said liquid, solution or extract and a product is
obtained capable of being transported stored or used with less danger than
hitherto.

We ISAAC SHIMWELL MCDOUGALL and JAMES THOMAS MCDOUGALL
both of 10 Mark Lane in the City of London Manufacturing Chemists 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 the treatment of corrosive or poisonous liquids, solutions
or extracts riz.-sulphuric acid hydrochloric acid, solutions of metallic salts (such
as those of zinc, copper, lead or iron) and tobacco extract, whereby they are
rendered into a solid or semi-solid or friable condition.
This is effected according to our invention by means of an infusorial earth (such
as keiselguhr) which possesses great power of absorption. We mix the liquid
solution or extract with the infusorial earth in such quantities or proportions that
the infusorial earth absorbs the said liquid, solution, or extract and a product is
obtained capable of being transported stored or used with less danger than
hitherto.
In carrying out our invention we find the following proportions are suitable
although they may be varied considerably.
Of any of the above named acids or solutions of metallic salts
which may be of any strength or of mixtures of them
Of infusorial earth
-
Of tobacco extract which may be of any strength
Of infusorial earth
-
-
75 parts by weight.
25 parts by weight.
70 parts by weight.
30 parts by weight.

page_text: These ingredients are thoroughly incorporated together by any well known
means. The product is of a semi-solid nature.
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-
The combination of poisonous or corrosive liquids with infusorial earth substan-
tially as and for the purposes bereinbefore described.
