New or Improved Compounds to be used for Disinfecting,
Deodorising, Germicide, Sanitary,

and

Purposes.
I, THOMAS MCMURRAY, of 9 Morrison Street, Glasgow Lanarkshire,
Manufacturing Chemist, do hereby declare the nature of my invention to be
as follows:-
My invention comprises the preparation of new and improved compounds and
their uses for disinfecting, deodorising, germicide and manuring purposes; and
which will be specially valuable as a base or retainer of products for the pre-
vention of disease among potatoes stored in bulk, or for the same purpose in the
plants while growing.
According to my invention I take furnace slag or lime or a compound mixture.
of slag and lime and mix it with carbon or charcoal and chemical re-agents to
form a new compound.
In carrying my said invention into practice I run the slag hot from the blast
furnace into water, which has the effect of separating the slag into a powdered or
granulated state thus saving the necessity for grinding or reducing the mixture..
Or the hot slag may be run into a vessel containing lime or limestone to calcine
and mix the two together.
I take vegetable carbon or charcoal of wood, peat, coal, or shale from the retort
and place it in an air-tight vessel until it cools.
I then take these mixtures preferably in the proportion of one part of the carbon
or charcoal to each three or four parts of the powdered or granulated slag prepared
with about the same quantity in weight of acid as the charcoal or as much of an
acidified solution of sulphuric, boracic, or other acids as it will carry, and
thoroughly mix them together, preferably in a pan, pug, or other mill, which
would cause the carbon to absorb the acidified solution, and reduce the mixture to
a granular or semi-dry state.
The carbon and the slag may each be treated separately with the acid solutions
before being mixed together to form the combined compound as above stated.
This new and improved compound would be used as a disinfectant, deodoriser,
and germicide, for distributing in a powdered state, over the floors of byres, stables,
poultry yards, dog kennels, and wherever animals are kept; and dung heaps,
privies, urinals, dry-closets, and other places, for the free acid in the compound to
absorb and fix the ammonia in the excreta, and thus add to the value of the
manure. In camp and barrack latrines, cattle ships and the like, it would
destroy all noxious gases emanating from decayed or decaying animal or vegetable
matter. In dairy-byres it destroys the germs of the diseases to which cattle are
subject, and it prevents in dairies germs contaminating the milk. In some cases I
may not use the carbon but mix the slag or lime or both with the acids to form a
disinfecting white wash for the walls of byres, stables and other places.

New or Improved Compounds to be used for Disinfecting,
Deodorising, Germicide, Sanitary, Manuring, and like
Purposes.
I, THOMAS MCMURRAY of 9 Morrison Street, Glasgow, Lanarkshire,
Manufacturing 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 :-
This invention comprises the preparation of new or improved compounds for
disinfecting, deodorizing, germicide, and for manuring purposes; and which will
be specially valuable as a base or retainer of products for the prevention of disease
among potatoes stored in bulk, or for the same purpose in the plants while
growing.
According to the invention I take furnace slag or lime, or a compound of slag
and lime and mix it with carbon or charcoal and chemical re-agents to form a new
compound.
In carrying the invention into practice I run the slag hot from the blast furnace
into water which has the effect of disintegrating the slag into a powdered or
granulated state thus saving the necessity for grinding or reducing the mixture,
or the slag may be run into a vessel containing lime or limestone to calcine and
mix the two together.
I take vegetable carbon or charcoal of wood, peat, coal or shale from the retort
and place it in an air-tight vessel until it cools. I then take a proportion of the
carbon or charcoal preferably one part to three or four parts of the powdered or
granulated slag the latter being first prepared with about the same quantity in
weight of sulphuric, boracic or other acid as there is of charcoal, or with as much
sulphuric, boracic or other acid in solution as the slag will carry, and thoroughly
mix them together, preferably in a pan, pug or other mill, whereby the carbon is
caused to absorb the acidified solution, and the mixture is reduced to a granular or
semi-dry state, or the carbon and the slag may each be treated separately with the
acid solutions before being mixed together to form the combined compound as
above stated.
This new and improved compound is suitable to be used as a disinfectant,
deodorizer and germicide by distributing it in a powdered state over the floors of
byres, stables, poultry-yards, dog-kennels, and wherever animals are kept; and
over dung-heaps, privies, urinals, dry-closets, and other places, and the free acid
in the compound absorbing and fixing the ammonia in the excreta, materially adds
to the value of the manure. In camps and barrack latrines, cattle-ships and the
like the use of the compound has the effect of destroying all noxious gases
emanating from decayed or decaying animal or vegetable matter, and in byręs its
use destroys the germs of the diseases to which cattle are subject, and it prevents
in dairies germs contaminating the milk. In some cases I may not use the carbon,
but mix the slag or lime or both with the acids to form a disinfecting white-wash
for the walls of byres, stables and other places.
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 :-
:-
1. The new or improved compound for disinfecting, deodorising, germicide and
for sanitary, manuring and like purposes consisting of disintegrated furnace slag or
lime or of a compound of slag and lime treated with acid or an acidified solution
and mixed with carbon or charcoal substantially as set forth.
2. The new or improved disinfecting white wash consisting of disintegrated

acidified solution substantially as described.
