Improvements in or relating to the Liberation or Recovery of Oils
and the like.
We, THE FISH UTILIZATION SYNDICATE LIMITED, Manufacturers, and
JOHN CHARLES WILLIAM STANLEY, Gentleman, both of 31 Queen Victoria
Street, in the City of London, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the liberation or recovery of oils essences and the
like by the destruction of the cells or substance containing them; the deodorisation
or purification is in some cases also effected.
In dealing with fish livers the invention may be carried into effect by first
extracting the oil that will rise by boiling and removing this by skimming and
then adding silicate of soda or other suitable silicate in suitable proportions and
skimming off the oil as it rises. The oil is then thoroughly washed to remove
any traces of alkali.
When treating animal or vegetable fats for deodorising and purifying, it is
rendered by boiling in water and a suitable proportion of silicate of soda added
and thoroughly mixed by hand or mechanism."

COMPLETE SPECIFICATION.
Improvements in or relating to the Liberation or Recovery of Oils
and the like.
We, THE FISH UTILIZATION SYNDICATE LIMITED, Manufacturers, and
JOHN CHARLES WILLIAM STANLEY Gentleman, both of 31 Queen Victoria
Street, in the City of London, 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 relates to the liberation or recovery of oils essences and the
like by the destruction or disruption of the cells or substances containing them.
In dealing with fish-livers for instance, the invention may be carried into effect
by first boiling them in water the oil that first rises to the surface of the liquid
in which they are boiled being removed by skimming; then silicate of soda or
silicate of potash or other suitable silicate is added in suitable proportions to the
liquid in which they are boiled and the boiling and skimming operations are
resumed. The presence of the silicate has the effect of destroying or breaking
open the oil-containing cells. A suitable proportion of silicate would be by
weight one thirty-second part of that of the livers treated. The oil is then

it owing to the use of an alkaline silicate and to remove other impurities."
When treating animal or vegetable fat for deodorising and purifying it is
rendered-by-boiling-in-water-in the presence of a suitable proportion of silicate
of soda thoroughly mixed by hand or mechanism with the fat; in this instance
the weight of silicate of soda should be say five per cent. by weight of the fat
treated.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is -
1. In the recovery or treatment of oils essences and the like, the employment
of silicate of soda or other silicate for the purpose specified.
2. Deodorising animal or vegetable fats by boiling them in the presence of
silicate of soda.
Dated this Thirtieth day of December 1896.
