TREATING WASTE OILY MATTERS TO OBTAIN A PRODUCT APPLICABLE TO THE MANUFACTURE OF SOAP, AND OTHER USEFUL PURPOSES IN THE ARTS." PROVISIONAL SPECIFICATION left
Year: 1856

page_text: LETTERS PATENT to Adolf Pollak, of the firm of A. M. Pollak, of Vienna,
in the Empire of Austria, for the Invention of "TREATING WASTE OILY
MATTERS TO OBTAIN A PRODUCT APPLICABLE TO THE MANUFACTURE OF SOAP, AND
OTHER USEFUL PURPOSES IN THE ARTS."
PROVISIONAL SPECIFICATION left by. the said Adolf Pollak at the
Office of the Commissioners of Patents, with his Petition, on the 14th.
January 1856.
I; ADOLF POLLAK; of the firm of A. M. Pollak, of Vienna, in the Empire of
Austria, -do hereby declare the nature of the said Invention for TREATING
WASTE OLLY-MATTERS TO OBTAIN A PRODUCT APPLICABLE TO THE MANUFACTURE OF
SOAP, AND OTHER USEFUL PURPOSES IN THE ARTS, to be as follows:-
My Invention consists of treating the residuum or waste matters left after.
the process of refining rape-seed 'oil 'has been completed, in order to obtain
therefrom a product applicable to the manufacture" of soap, and to other useful
purposes in the arts. The refuse left by the refining process is generally black
in colour, owing to the presence of sulphuric acid. In the first place, I purify
this refuse matter, by washing it with water, or by subjecting it to the action of
steam, until no taste of acid is found in it; by the addition of caustic soda and
lime or potash to this product, I'make soft-or hard soap by the hot or cold'
process of soap making, as now practised; and this product of the refuse
matter, treated according to this my Invention, with the necessary alkaline

page_text: matters, may be used alone, or with the addition of other animal or vegetable
matters, for making soap. This product so obtained from the waste left
from refining rape-seed oil is applicable to other useful purposes in the arts.
Instead of depriving the waste or residuum of the acid by the means herein-
before described, I may do so by mechanical means, and the waste left by
refining oils from other seeds thau rape may be treated in the above manner to
yield a useful product.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
-
by the said Adolf Pollak in the Great Seal Patent Office on the
14th July 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLF
POLLAK, of the firm of A. M. Pollak, of Vienna, in the Empire of Austria,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Adolf Pollak, Her special licence that I, the said Adolf Pollak, my
executors, administrators, and assigns, or such others as I, the said Adolf
Pollak, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for TREATING WASTE OILY MATTERS
TO OBTAIN A PRODUCT APPLICABLE TO THE MANUFACTURE OF SOAP, AND OTHER USEFUL
PURPOSES IN THE ARTS, upon the condition (amongst others) that I, the said
Adolf Pollak, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner.
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Adolf Pollak, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-

page_text: The object of this Invention is to utilize the residium or refuse matter
resulting from the process of refining rape-seed and other oils. In the process
of refining, these oils are usually treated with sulphuric acid, which precipitates
a large quantity of feculent oily matter, which product is at tho present time
thrown away as useless.
Now, these improvements consist in rendering such waste oily matters useful
for the manufacture of soap, and applicable also to other purposes in the arts.
The refuse oily matter is usually black in colour, arising from the presence of
sulphuric acid; and the object of the operation, herein-after described, is to
free the refuse matter of acid, which I effect by washing it with hot water in a
vessel suitably arranged for the purpose, and so fitted that the contents may be
agitated or stirred from time to time, as required; or otherwise I subject the
mass to the action of steam; but in either case I continue the operation of
washing or steaming until there is no longer any acidulous taste left in the
refuse matter under operation, or until the oily matter no longer alters the
colours of the test papers usually employed to detect the presence of acids.
After this treatment, the whole is allowed to stand for a time, and the clear
oily matter drawn off, which will be fit to manufacture into soap by the
addition of caustic soda and lime, or potash, and it may be made into either
hard or soft soap by any of the processes now ordinarily employed for the
purpose; but as these operations form no part of my Invention, it is unneccs-
sary for me to enter into a particular description of the same.
In some cases
it may be preferable to use mechanical means to deprive the refuse oily matter
of acid in order to obtain a useful product therefrom.
Having described the nature of my Invention, and the means of carrying
the same into practical effect, I wish it to be understood that what I claim
under the herein-before in part recited Letters Patent is, treating waste
or refuse oily matters in the manner and by the means herein-before described
for the purpose of obtaining a useful product therefrom.
In witness whereof, I, the said Adolp Pollak, have hereunto set my
hand and seal, this Eighth day of July, in the year of our Lord One
thousand eight hundred and fifty-six.
