Complete Specification Left, 11th Feb., 1890-Accepted, 16th May, 1890
PROVISIONAL SPECIFICATION.
Manufacture of Bleaching and Disinfecting Liquor.
We, EUGENE HERMITE, EDWARD JAMES PATERSON, and CHARLES FRIEND
COOPER all of Pownall Road Dalston in the County of Middlesex, Electrical
Engineers do hereby declare the nature of this invention to be as follows:-
-
Our invention relates to the manufacture of bleaching and disinfecting liquor by
treatment of the known mineral carnallite in the following nauner.
We mechanically separate blocks of crude carnallite into three paris, one of which
is a double salt of magnesium chloride and potassium chloride. Through a solution
of this salt we pass a current of electricity so as to effect certain decomposition which
renders the resulting liquor particularly available for bleaching and disinfecting.
The presence of the potassium chloride, which becomes partly decomposed, has au
action on the magnesium chloride such that a certain amount of magnesia is set free
in the liquor rendering it alkaline, which is found to be advantageous. The electro-
lysing may be applied to the solution by itself, producing the bleaching or disinfecting
liquor which may be stored or the electrolysing may be applied to the liquor while
it is circulating in presence of the material to be bleached or disinfected.
Dated this 16th day of May 1889.

COMPLETE SPECIFICATION.
Manufacture of Bleaching and Disinfecting Liquor.
We, EUGENE HERMITE, EDWARD JAMES PATERSON and CHARLES FRIEND
COOPER all of Pownall Road, Dalston in the County of Middlesex, Electrical
Engineers, 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 manufacture of bleaching and disinfecting liquor by
treatment of the known mineral carnallite in the following manner. Blocks of crude
carnallite usually consist of parts or layers, one of which is a double salt of magnesium
chloride and potassium chloride. We separate this part mechanically from the others,
through a solution of it we pass a current of electricity as. described in our prior
Specifications Nos. 146738, 19937 and 539387 so as to effect certain decomposition
which renders the resulting liquor particularly available for bleaching and disinfecting.
The presence of the potassium chloride which becomes partly decomposed has an
action on the magnesium chloride such that a certain amount of magnesia is set free
in the liquor rendering it alkaline which is found to be advantageous. The electro-
lysing may be applied to the liquor while it is circulating in presence of the material
to be bleached or disinfected.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is.
The manufacture of bleaching and disinfecting liquor by electrolysing a solution
of the double salt of magnesium chloride and potassium chloride found in carnallite.
