Manufacture of Acetates for Warming and Heating Purposes.
GRAINGER HESLOP of Deptford Hall, Sunderland in the County of Durham
Coal Viewer and Chemical Works Manager do hereby declare the nature of this
invention to be as follows :-
:-
This invention consists in using mother liquors (a bye product or residuum)
resulting from the manufacture of acetates of soda, potash or other bases, but
preferably from the soda base after it has been so exhausted that it no longer yields
crystals, for use in foot warmers or other heating appliances, and which liquors
have (to the best of my knowledge and belief) never been heretofore used for these
purposes.

COMPLETE SPECIFICATION.
An Invention for the Application of a Bye Product of the
Manufacture of Acetates for Warming and Heating Purposes.
GRAINGER HESLOP of Deptford Hall Sunderland in the County of Durham,
Coal Viewer and Chemical Works Manager, 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 consists in using mother liquor (a bye product or residuum)
resulting from the manufacture of acetates of soda, potash, or other bases but
preferably from the soda base after it has been so exhausted that it no longer
yields crystals for use in foot warmers or other heating appliances.
The object of my invention is to effect a saving by the utilisation of such
residuum or bye product as is above described and which possesses the property of
retaining its heat so as to continue its emission of warmth to its surroundings for
many times as long as water.
As at all known temperatures in this country the said bye product remains liquid
and does not crystallize, no shaking or other attention is necessary after the
receptacle with the heated liquid has been placed in situ until reheating becomes
necessary again.
The said liquid (bye product) is perfectly safe and in no way injurious to work
amongst, and may be heated by any of the modes in use for hot water foot, or
other, warmers and the tins or other receptacles at present in use whether with
water or other substances are equally suitable for the said liquid, thus obviating
any outlay for special receptacles.
My invention can be applied to a great variety of purposes, amongst which
are foot warmers for railway and other carriages, footstools for houses churches,
offices or other buildings and also for various hospital and sick room uses, hot
houses &c.
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 use or application and employment of mother liquor (a bye product or

page_text: residuum) resulting from the manufacture of acetates, for warming and heating
purposes generally by the heat emitted or thrown off by such liquor after being
heated.
