Year: 1856

page_text: LETTERS PATENT to Germain Barruel, Chemist, of No. 24, Rue Haute-
feuille, in the City of Paris, for the Invention of "IMPROVEMENTS IN
TREATING COTTON SEED."
Sealed the 14th November 1856, and dated the 22nd May 1856.
PROVISIONAL SPECIFICATION left by the said Germain Barruel at the
Office of the Commissioners of Patents, with his Petition, on the
22nd May 1856.
I, GERMAIN BARRUEL, Chemist, of No. 24, Rue Hautefeuille, in the City
of Paris, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN TREATING COTTON SEED," to as follows:-
This Invention consists in obtaining products from cotton seed by distillation.
The products thus obtained are gas suitable for illumination, paraffine, and
also an oil which may be used for lubricating and other purposes, besides
which other products are obtained similar to those ordinarily obtained in the
manufacture of gas. The residue left in the retort may be treated to obtain
potash therefrom.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GERMAIN
BARRUEL, Chemist, of No. 24, Hautefeuille, in the City of Paris, send
greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, 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
Germain Barruel, Her special licence that I, the said Germain Barruel, my
executors, administrators, and assigns, or sucli others as I, the said Germain
Barruel, 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
yend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an. Invention for "IMPROVEMENTS IN TREATING
COTTON SEED," upon the condition (amongst others) that I, the said Germain
Barruel, 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 Germain Barruel, do hereby declare
the nature of the 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 thereof, that is to say:-
This Invention consists in obtaining products from cotton seed by distillation.
The products thus obtained are gas suitable for illumination, paraffine, and also
an oil which may be used for lubricating and' other purposes, besides which
other products are obtained similar to those ordinarily obtained in the manu-
facture of gas. The residue left in the retort may be treated to obtain 'potasli
therefrom..
And in order that my said Invention" may be most fully understood" and
readily carried into effect, I will proceed to describe the means pursued
by me.
The cotton seed, either. whole or in a crushed state, is submitted to the action

page_text: of heat in a close vessel, when the organic matters decompose in the ordinary
manner, and produce gas, pyroligneous acid, a considerable quantity of
ammonia, and a large proportion of fatty matters of great value. The cinders
produced by the carbonization of the grain contain, together with other salts,
an important quantity of potash which may be dissolved out by water. The
apparatus which I employ for conducting the distilling process is arranged so
as to condense the fatty matters and also the aqueous products of the distilla-
tion; and apparatus of the ordinary description is added for purifying the gas
by means of lime, which absorbs the carbonic acid, the ammonia having been
first separated by means of acid or otherwise. The cinders produced by the
carbonization of the grain are treated in the ordinary manner to separate the
potash therefrom. The fatty matters obtained may be re-distilled or otherwise
treated, according to the purpose to which they are to be applied.
In witness whereof, I, the said Germain Barruel, have 'hereunto set
my hand and seal, this Fourteenth day of November, in the year of
our Lord One thousand eight hundred and fifty-six.
Witness,
