Lancaster. IMPROVEMENTS IN CARBONISING WOOL, WOOL WASTE, RAGS, AND
OTHER SIMILAR ANIMAL FIBRE." [A communication from abroad by Dr. Adolf
Frank, of Charlottenburg, in the German Empire.]
'
According to the present Invention the carbonisation of wool, wool waste, rags,
and other similar animal fibre is effected by means of chloride of magnesium
solution of a strength of about 1:07 to 11 specific gravity, or by means of liquors
-containing chloride of magnesium, such as are produced in various chemical manu-
factures. For this purpose the wool is steeped in the solution or liquor. so as to
become thoroughly saturated thereby; it is then removed and dried either by a
centrifugal machine or in a drying chamber or other suitable known drying
apparatus. The wool is then placed in a carbonising chamber where the carboni
sation is effected under the decomposition of the chloride of magnesium by means
of water into hydrochloric acid and oxide of magnesium. This is effected in from
30 to 90 minutes, according to the quantity and quality of the wool. On removal
from the carbonising chamber the wool is at once washed in clean fresh water, or in

with the chloride of magnesium liquor produced in the manufacture of bromine, the
wool is washed in water acidulated by hydrochloric acid so as to dissolve the oxides
of manganese and of magnesium at the same time.

HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVEMENTS IN CARBONISING WOOL, WOOL WASTE, RAGS, AND
OTHER SIMILAR ANIMAL FIBRE." A communication from abroad by Dr. Adolf
Frank, of Charlottenburg, in the German Empire.
According to the present Invention, the carbonisation of wool, wool waste, rags,
and other similar animal fibre is effected by means of chloride of magnesium
solution of a strength of about 1.07 to 11 specific gravity, or by means of liquors
containing chloride of magnesium, such as are produced in various chemical manu-
factures. For this purpose the wool is steeped in the solution or liquor so as to
become thoroughly saturated thereby; it is then removed and dried either by a
centrifugal machine or in a drying chamber or other suitable known drying
apparatus. The wool is then placed in a carbonising chamber, where the carboni-
sation is effected under the decomposition of the chloride of magnesium by means of
water into hydrochloric acid and oxide of magnesium. This is effected in from 30
to 90 minutes, according to the quantity and quality of the wool. On removal
from the carbonising chamber the wool is at once washed in clean fresh water, or if
the chloride of magnesium solution or liquor contained manganese, as is the case
with the chloride of magnesium liquor produced in the manufacture of bromine, the
wool is washed in water acidulated by hydrochloric acid so as to dissolve the oxides
of manganese and of magnesium at the same time.
Having thus described the nature of the said Invention and in what manner the
same is to be performed, as communicated to me by my foreign correspondent, I
claim,―
First. The use for carbonising wool, wool waste, rags, and other animal fibre, of
chloride of magnesium, or of liquors or lyes containing chloride of magnesium,
such as are produced in various chemical manufactures, substantially as herein.
described.
Second. The method herein described of applying chloride of magnesium, or of
liquors or lyes containing the same, to the carbonisation of wool, wool waste, rags,
and other animal fibre.

:
Third. The process herein described of first steeping the wool or other animal

with acidulated water in order to dissolve the oxides formed.
In witness whereof, I, the said Henry Simon, have hereunto set my hand
and seal, this Ninth day of May, in the year of our Lord One thousand
eight hundred and seventy-eight.
