Improvements in the Manufacture of Metallic Oxides.
We, ARTHUR BRIN, of No. 59 Brompton Crescent, in the County of Middlesex,
Engineer and Chemist, and LÉON QUENTIN BRIN, of 7 Rue Gavarni, Paris, in the
Republic of France, Engineer and Chemist, do hereby declare the nature of this
Invention to be as follows:-
Our Invention has for its object to expedite and cheapen the cost of manufacture
of metallic oxides at the same time producing them in a condition of great purity.
According to our Invention we heat the metal which is to form the base of the
oxide, and whilst the said metal is in a molten condition we pass oxygen thereinto.
The metal is contained in an enclosed vessel or receptacle from which a passage leads
into a chamber in which the oxide, which is formed and passes off from the first vessel
or re eptacle in the condition of vapour, is deposited. This chamber is provided with
means for removing the oxide and for allowing of the passing off of remaining vapour
to a condenser, if so required.

Improvements in the Manufacture of Metallic Oxides.
We ARTHUR BRIN of 59 Brompton Crescent in the County of Middlesex Engineer
and Chemist and LEON QUENTIN BRIN of 7 Rue Gavarni Paris in the Republic of
France Engineer and Chemist 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 the following statement:-
Our Invention has for its object to expedite and cheapen the cost of manufacture
of metallic oxides at the same time producing them in a condition of great purity.
According to our Invention we heat the metal which is to form the base of the
oxide and whilst the said metal is in a molten condition we pass oxygen therethrough
or we pass the oxygen into the vapours or fumes driven off from the metals by the
heating operation. Referring to the accompanying drawing the metal is contained
in an enclosed vessel receptacle or crucible A situated in the furnace B and having an
opening, at a² for charging the retort and removing its spent contents. Into the
receptacle or crucible A. a pipe a leads through which the oxygen is admitted to the
contents of the crucible. From the said vessel A a passage or pipe C leads into a
chamber D in which is deposited the oxide which is formed and passes off from the
first vessel A in the form of vapour. The chamber D is provided with means for
removing the oxide which is shewn as consisting of the outlet d with a cover d2 over
its outer end and a cover also at d³ which covers an opening by which the workman
can gain access to the contents for removing them. The remaining vapour passes off
by the pipe e to a condenser or other place at which it is desired to collect and utilize
them. This preferably consists of a vessel F containing water beneath the surface
of which the end of the pipe e dips, the fumes being thereby condensed and precipitated.
The oxygen may be injected into the apparatus so as to meet the metallic vapours
after they have been driven off by the heating operation. The Invention is applicable
to the production of oxides of the metals generally such as for the production of the
oxides of silver, cobalt, tin, mercury, chrome, cinnabar, vermillion, lead, zinc, copper,
antimony, bismuth, and manganese. We wish it to be understood that we have
illustrated the apparatus merely to assist the explanation of the manufacture and that
we do not limit ourselves to the use of the construction or arrangement of the apparatus
as illustrated.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is.
First. In the manufacture of metallic oxides submitting the metal from which the
oxide is to be produced, to heat and to the action of oxygen substantially as herein-
before described whether the oxygen be applied to the solid contents of the retorts or

page_text: vessels or be caused to meet the fumes or vapours after they arise from the said
contents.
Second. In the manufacture of metallic oxides submitting the metal from which the
oxide is to be produced, to heat and to the action of oxygen and then conducting the
vapours into a depositing chamber in which the oxides are collected, and from which
they can be removed substantially as hereinbefore described.
Third. In the manufacture of metallic oxides submitting the metal from which the
oxide is to be produced, to heat and to the action of oxygen and then conducting the
vapours into a depositing chamber the remaining vapours from which are caused to
pass beneath water or other liquid substantially as and for the purposes hereinbefore
described.
