page_text: I ARTHUR BRIN, Civil Engineer, 59 Brompton Crescent, Brompton Road London
S.W. do hereby declare the nature of this invention to be as follows:-
All the efforts we have so far made in the construction of apparatus for the
production of oxygen have been directed towards the production of the largest
possible amount of oxygen in the least time, and with the least expenditure of
mechanical work.
In this I believe I have completely succeeded and in the present specification I am
about to describe the different parts of a rotary retort with several compartments,
which I believe will realize completely the double effect of peroxidation and deoxida-
tion of barium, no matter what amount it contains.
The retort which forms the principal subject of the present specification have a
cylindrical shape like a drum; they are formed of solid iron, and there is fixed at each
extremity.
I. A large metallic joint to close hermetically the two ends of the retort. In the
center of these large joints is fixed another much smaller whose diameter may be varied
according to the inlet and outlet of gas, and in accordance with the volume that are
being produced :
II. In the exterior diameter of the two large joints, there is a smoth surface in all
its diameter. This surface is found at the two ends of the retort and rests upon a
serie of rollers arranged in a circular ring, which have for object to permit the retort
to turn upon itself with slight mechanical effect.
III. A transverse interior section of this retort shows a number of compartments,
of which the lower part is pierced by a multitude of holes, in order to allow the air
to enter under pressure, and to provide for the rapid production of vacuum upon cach
particle of barium, that the aforesaid compartments contain.

An Apparatus for the Extraction of Oxygen and Nitrogen from the
Atmospheric Air.
ARTHUR BRIN, Engineer, 59 Brompton Crescent, Brompton Road London S.W.
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by tho
following statement :-
All the efforts we have so far mado in the construction of apparatus for the
production of oxygen have been directed towards the production of the largest
possible amount of oxygen in the least time, and with the least expenditure of
mechanical work.
In this I believe I have completely succeeded and in the present specification I am
about to describe the different parts of a rotary retort with several compartments,
which I believe will realize completely the double effect of peroxidation and deoxidation
of barium, no matter what amount it contains.
The retort which forms the principal subject of the present specification is
illustrated in the accompanying drawings in which figuro 1 shews a transverse
section and figure 2 a longitudinal section of one of the end portions. Figure 3
is a front view. The retort a is of cylindrical shape and formed of strong iron. The
retort is closed hermetically at each end by a head b to which is connected an inlet
or outlet pipe c for the gas.
II. The exterior diameter of the cover and flange of the retort a runs upon
rollers d arranged circularly, which have for object to permit the retort to turn
upon itself with slight mechanical effort.
III. A section of this retort shows a number of compartments, of which the
lower part and upper part of each alternate partition is pierced by a multitude of
holes, in order to allow the air to enter under pressure, and to provide for the rapid
production of vacuum upon each particle of barium, that the aforesaid compartments
contain.
PEROXIDATION AND DEOXIDATION.
In order that the effect of the peroxidation or of the deoxidation may be complete,
one of these partitions will offer its openings to the passage of the air at the
bottom, when the partition that follows it, shall have its corresponding openings at
the top. Then the openings in the partitions will allow the air to traverse all the
compartments during the peroxidation and it will be forced during the peroxidation
and during the time of the rotation of the retort to travel from the top to the bottom
in the compartments, while by the rotary movement imparted to the retort, all the
portions of the barium that the compartments contain, will be presented to the current
of air or to the vacuum, in order that the air or the vacuuin may operate rapidly
upon each particle, whether with a view to deoxidation or peroxidation.

page_text: ORGANISATION OF A COMPLETE FACTORY.
The difference of temperature being given which exists between the peroxidation
and the deoxidation of barium, I recognize that practically the retorts ought to
be arranged in three separate furnaces, divided by walls of some refractory
material.

page_text: When the deoxidation of No. III is effected, the change of taps of tho pipes will
deoxidise No. II, and at the same time the contents of furnace No. I will be
peroxidised by the fan or air pump.
It is thus that the pumps of deoxidation and the pump of peroxidation will be
transferred by the movement of the taps from No. I to No. 11 and from No. II to
No. III, without any stoppage of the production of oxygen or of nitrogen.
I think I have united in this arrangement the principal elements necessary for the
continuous and practical production of oxygen and of nitrogen.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
I. The aforesaid rotary movement applied to the retorts destined to produce the
oxygen and the nitrogen.
II. The interior arrangement of the perforated compartments which in consequence
of the rotary movement imparted to the retort allow every part of the barium
contained in the retort to be simultaneously submitted to the action of the compressed
air, as also to the vacuum produced by the pumps specially constructed for that
purpose.
III. The new arrangement micro-pyrometric acting by the direct agency of the
dilatation of the retort.
IV. The coating of the exterior diameter of the retort, in order to protect it against
the corrosivo action of the flames which heat it.
V. The application of rotary metallic joints enabling the retort to resist the
pressure of the air forced in, and also the vacuum produced by the pumps,
without the least possibility of leakage.
