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 our said Invention to be
as follows:-
Our Invention consists in the application of a constant supply of oxygen for the
continuous production of chlorine.
We place oxide of manganese or bioxide of manganese or other equivalent oxide in
a retort of lead glass or other suitable material and we add thereto hydrochloric acid..
The vessel containing these materials is heated preferably to about 100° Centigrade
which may be effected by means of hot water or by a steam coil.
The generation of chlorine takes place instantaneously and it would cease almost
immediately owing to the double reaction that takes place at the same time but we
admit oxygen gas amongst the materials which reoxidises the manganese or the like
and the generation of chlorine then proceeds continuously and regularly the hydro-
chloric acid being supplied as required.
Directly it is produced the chlorine is or may be subjected to electric action---
which may be effected in an apparatus such as is used in the production of ozone from
oxygen and called an ozono-generator.
When the chlorine so produced is employed in vessels or chambers hermetically
closed it is easy to recover the portion not absorbed and to cause it to pass again
through the generating retort and afterwards to follow the same path as before.
A most remarkable economy is thus effected as well as the utilisation of an acid
which costs little and is usually a refuse material.
Moreover the oxide being continually self reconstituted, its employment is also very
economical.

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 that is to say :-
Our Invention consists in the application of a constant supply of Oxygen for the
continuous production of Chlorine.
We place Oxide of Manganese or Bioxide of Manganese or other equivalent
Oxide in a Retort of glass earthenware or other suitable material and we add thereto
Hydrochloric Acid.
The vessel containing these materials is heated preferably to about 100° Centigrade
which may be effected by means of boiling water or by a steam coil.
The generation of Chlorine takes place instantaneously and it would cease almost
immediately owing to the double reaction that takes place at the same time but we
admit Oxygen gas amongst the materials which reoxidizes the manganese or the like
and the generation of Chlorine then proceeds continuously and regularly the hydro-
chloric acid being supplied as required.
Directly it is produced the Chlorine is or may be subjected to electric action which
may be effected in an apparatus such as is used in the production of Ozone from
Oxygen and called an Ozone generator.
When the Chlorine so produced is employed for treating matters in solution with
water in vessels or chambers hermetically closed it absorbs hydrogen and liberates
oxygen & the Oxygen so liberated can be led back so as to pass through the generating
retort and so act to revivify or assist in revivifying the Oxide in the manner hereinbefore
explained.
A most remarkable economy is thus effected in the production of Chlorine the
Hydrochloric Acid costing little (being often obtained as a refuse material) and to the
Oxide being continually revivified as aforesaid.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is
First. The production of Chlorine in a continuous manner substantially as herein-
before described.
Second. The production of electrified Chlorine in a continuous manner substantially
as herein before described.
