Year: 1869

page_text: LETTERS PATENT to Ludwig Mond, of Farnworth-within-Widnes, in
the County of Lancaster, Chemist, for the Invention of "IMPROVE-
MENTS IN UTILIZING PRODUCTS ARISING FROM SODA AND POTASH WASTE,"
Sealed the 2nd October 1869, and dated the 7th April 1869.
PROVISIONAL SPECIFICATION left by the said Ludwig Mond at the
Office of the Commissioners of Patents, with his Petition, on the
7th April 1869.
I, LUDWIG MOND, of Farnworth-within-Widnes, in the County of
Lancaster, Chemist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN UTILIZING PRODUCTS ARISING FROM SODA AND POTASH
WASTE," to be as follows:-
My Invention relates to the utilization of the residue which is
obtained from soda and potash waste after these substances have been
oxidized and lixiviated for the separation of sulphur and sulphur
compounds. For this purpose I propose to use this residue in the
manufacture of soda and potash in the process called balling by,
substituting it for a portion of the limestone or other such substance

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LUDWIG
MOND, of Farnworth-within-Widnes, in the County of Lancaster,
Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Ludwig Mond, Her special license
that I, the said Ludwig Mond, my executors, administrators, and
assigns, or such others as I, the said Ludwig Mond, 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 "IMPROVEMENTS IN
UTILIZING PRODUCTS ARISING FROM SODA AND POTASH WASTE," upon the con-
dition, amongst others, that I, the said Ludwig Mond, by an instrument
in writing under my hand and seal, 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 Ludwig Mond, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
My Invention relates to the utilization of the residue which is
obtained from soda and potash waste after these substances have been
oxidized and lixiviated for the separation of sulphur and sulphur com-

page_text: pounds as now commonly practiced. For this purpose I propose to
use the residue in the manufacture of soda and potash in the process
called balling by substituting it for a portion of the limestone or other
such substance usually employed. The proportion of this residue to the
limestone or other similar material will vary according to its composition
and the quantity of water it contains, and may readily be determined
by analysis or experience. The proportions I have found generally to
answer are fifty pounds of the limestone to one hundred pounds of
the residue in place of one hundred pounds of limestone usually,
employed, and this mixture is used in the balling process precisely in
the same manner as is now adopted.
By the use of the above-mentioned residue I accomplish two objects,
for the more expensive material is economised, and the means of getting
rid of the residue is attained.
Having thus described and ascertained the nature of my said
Invention, and the manner in which the same is to be performed, I
desire it to be understood that I claim as secured to me under the above
in part recited Letters Patent, the use of the above-described residue for
the purposes above set forth, and in place of limestone or other such
substance usually employed.
In witness whereof, I, the said Ludwig Mond, hath hereunto set
my hand and seal, this Second day of October, in the year of our
Lord One thousand eight hundred and sixty-nine.
Witness to the signature of
Ludwig Mond,
