page_text: LETTERS PATENT to Otto Braun, of Berlin, for the Invention of "A
NEW METHOD AND A NEW MACHINE FOR SEPARATING BODIES OF ANY KIND
FROM GASES OF ANY KIND, BY PREFERENCE APPLICABLE FOR GETTING THE
PROVISIONAL SPECIFICATION left by the said Otto Braun at the
Office of the Commissioners of Patents, with his Petition, on the
8th April 1875
I, OTTO BRAUN, of Berlin, do hereby declare the nature of the said
Invention for "A NEW METHOD AND A NEW MACHINE FOR SEPARATING BODLAS
OF ANY KIND FROM GASES OF ANY KIND, BY PREFERENCE APPLICABLE FOR GETTING
THE USEFUL SUBSTANCES OUT OF THE SMOKE OF PIT COAL," to be as follows:
After having cooled the smoke, if possible by making use of its
warmness, I turn into dust as much water in it as cannot evaporate
(that little water drops are hanging in the smoke), and expose it to the
centrifugal power by forcing it through a rotating vessel. By this
operation the drops of water now saturated with the substances of the
smoke (chiefly with compounds of ammonia) are deposed with tar and
soot, and by this way separated from the gases, which escape clear.

page_text: If it is possible to cool the smoke as much as to condense a part of the
stcam which it always contains, injection of water is not required.
The machine is applicable for providing theatres, worsted spinnings,
and other buildings with purc, cool, humid air, as one part of the injected
water moistens and cools by its evaporation, and the fluid rest sinking
upon the circumference of the rotary vessel takes along with it all
impurities of the air.
To get solid bodies dry out of gases, for instance oxide of zinc out of
air (in preparing zinc white), I vary only somewhat the form of the
vessel and the valves
To get a gas out of gases (for instance muriatic acid gas out of air)
I inject water or another absorbing substance, but it is not possible to
separate mixed gases without condensing or absorbing at least one of them.
The chief part of the machine is a vessel which is divided in two
unequal compartments by a plate and fixed upon a hollow shaft. The
said vessel is not quite cylindrical, but the diameter increases to the

Letters Patent, bearing date the Eighth day of April, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
cighth year of Her reign, did, for Herself, Пer heirs and successors, give
and grant unto me, the said Otto Braun, Icr special license that
I, the said Otto Braun, my exccutors, administrators, and assigns,
or such others as I, the said Otto Braun, 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 " A NEW METHOD AND A NEW MACHINE FOR SEPARATING
BODIES OF ANY KIND FROM GASES OF ANY KIND, BY PREFERENCE APPLICABLE FOR
GETTING THE USEFUL SUBSTANCES OUT OF THE SMOKE OF PIT COAL," upon the
conditions (amongst others) that I, the said Otto Braun, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hands and scals, 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 Otto Braun, 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, reference being had to the accompanying
Drawing forming a part of this Specification:-
After having cooled the smoke, if possible by making use of its
warmness, 1 turn into dust as much water in it as cannot evaporate
(that little water drops are hanging in the smoke), and expose it to the
centrifugal power by forcing it through a rotating vessel. By this
operation the drops of water now saturated with the substances of the
smoke (chiefly with compounds of ammonia) are deposed with tar and
soot, and by this way separated from the gases, which escape clear.
If it is possible to cool the smoke as much as to condense a part of the
steam which it always contains, injection of water is not required.
The machine is applicable for providing theatres, worsted spinnings,
and other buildings with pure, cool, humid air, as one part of the injected

page_text: water moistens and cools by its evaporation, and the fluid rests, sinking
upon the circumference of the rotary vessel, takes along with it all
impurities of the air.
To get solid bodies dry out of gases, for instance, oxyde of zinc out of
air (in preparing zinc white), I vary only somewhat the form of the t
vessel and the valves.
To get a gas out of gases (for instance, muriatic acid gas out of air)
I inject water or any other absorbing substance, but it is not possible to
separate mixed gases without condensing or absorbing at least one of
them.
The chief part of the machine is the vessel K, which is divided in two
unequal compartments P and Q by the plate N, and fixed upon the
hollow shaft A, B. The vessel K is not quite cylindrical, but the diameter
increases in the middle, where in a furrow G are placed the valves II, II,
H, II. These valves can be opened all at once by means of a drag
wheel J, and they are shut all at once (the machine going) by the
centrifugal power of the valve rods when the brake of the wheel J is set
free. The hollow shaft A, B, 1s turned by means of two pulleys C, C,
between six friction wheels O, O, instead of two pillows. Within the
pulleys arc annular concavities to place in the flanches D, D, of the
tubes E and F. On cach side of the plate N within the vessel K are
vanes M, M, fixed like those of a fan. Round about the furrow G is
fixed the furrow L, from the deepest point of which the tube T com-
municates with a tank.
The frame of the machine is not described and not delineated, as it has
not a special form.
The form of the vessel, the direction of the shaft, the number and the
form of the vanes and the valves, the places of the pulleys and of the
water shuts, and any other part of the machine can be varied manifold;
besides, I can arrange the machine that it works as a fan too.
After having put in rotation the vessel K I fill with water the
pulleys C, C. This water arranges itself all round the inner circumference
of the pulleys, and makes an bermetique shut between the fixed tubes E
and F and the rotating shaft A, B, because the borders of the
flanges D, D, plunge in it. Now the smoke over saturated with water
(by having cooled it only, or by having injected water too) is pulled in

page_text: the tube E by a fan or by other means. The smoke passes the vessel K
by the way marked with arrows. In the compartment P its rotary
velocity increases, in the compartment Q it is retarded by the vancs.
The injected or condensed water saturated with ammonia and the
other substances of the smoke is gathered with tar and soot in the
furrow G, and the gases escape clear out of the tube F From time to
time, perhaps every ten minutes, I put the brake to the drag wheel J
during some seconds to open the valves II, II, II, I, for a short time.
The contents of the furrow G spouts out of the valves into the furrow L,
whence it runs by the tube T in a tank.
Having thus fully described my said Invention, and the manner of
performing the same, I wish it understood that I claim,―
First. The described method to expose the centrifugal power in a
rotating vessel the smoke after having saturated it with water by
cooling only or by injection of water too.
Second. This method, turning into dust liquids in gases of all kind,
and expose this mixture in a rotary vessel to the centrifugal power for
separating any body out of any gas.
Third. This method, exposing gases which contain solid bodies in a
rotary vessel to the centrifugal power without cooling or injecting
liquids (spark catcher).
Fourth. The described and delineated arrangements to take the sub-
stances deposed therein out of the rotary vessel without disturbing its
velocity.
In witness whereof, I, the said Otto Braun, have herounto set
my hand and scal, this Twenty-seventh day of September, in
the year of our Lord One thousand eight hundred and seventy-
