Middlesex, Electrical Engineer, do hereby declare the nature of my invention
for " IMPROVEMENTS IN UTILIZATION AND
GALVANIC BATTERIES," to be as follows:-
REGENERATION OF BYE-PRODUCTS OF
My invention relates to improvements in utilization and regeneration of bye-
products of Galvanic Batteries, and consists in novel and improved means of
treating the residues, or bye-products of Galvanic Batteries, and especially of those
which have an alkaline solution for exciting liquids.
In such batteries the alkaline solution will dissolve the zinc oxide, which is
formed in the battery during action, into, what is called, zincate alkaline. In time
these solutions become saturated with zinc oxide, and ought to be replaced by a
fresh exciting liquid or liquids. To reduce the cost of working such batteries i.e. to
reuder the production of electricity even profitable; I propose to treat the said
zincate alkaline solutions, or residues in the following ways viz:-
1 By the addition of water at a suitable temperature, and under suitable pressure,
with, or without salts or oxides, or acids, or other chemical composition or mixture
of them. By this operation zinc oxide in hydrate, or anhydrate state, will be
thrown as precipitiate, which can be used as a pigment. The remaining solution
will contain more weak solution of alkali, or its salts, or combinations.
By any
suitable means or process, this can be converted into a strong solution of alkali,
which can be used again in batteries, or even the said alkali, or salts, can be
obtained in solid state.
2, By freezing, roasting, drying, or otherwise solidifying and melting (or either
of these processes), in proper manner, by heat, or otherwise, and then by a subse-
quent treatment of the said residues by water, (with or without the addition of
other substances to it), of suitable temperature, and under necessary pressure,
I obtain a solution of caustic alkaline metal, or salts of it, which can be treated
and used afterwards as desired.
3, By sending under suitable conditions and temperature, a current of a gas, or
gases, or vapours of the bodies, such as Iodine, Bromine, Chlorine or Flourine, or
any mixture of them, I shall convert the alkali of said residues, i.e. zincate alkaline,
into valuable salts of the said alkali, such as chlorates, chlorides, hypo or per
CD471

page_text: iodates, and such like. The air steam or other gases or vapours may be added to
the said gases or vapours in any desirable proportions. Instead of using the said
bodies in their gaseous state they may be used separately, or combined, or even
mixed with other substances, in any other form, solid or liquid, or in their chemical
combinations, or salts.
The oxides, or chlorides, Iodides and such like of the metals, or their equiva-
lents can be converted into previous state, by sending a current of air, oxygen,
chlorine or other above mentioned gases, or vapours of the bodies or solution of the
same, or their salts or combination or by additions to these of such like substance
in a solid or liquid state.
Either of these processes separately or together, or in combinations with the
other above mentioned process, can be applied, or used for similar purpose in any
other forms of batteries.

DIEVITICATION,
JOHN RAPIEFF of Hurst Lodge Hadley Wood, Barnet, in the County of
Middlesex, Electrical Engineer, do hereby declare the nature of my invention
for IMPROVEMENTS IN UTILIZATION AND REGENERATION OF BYE-PRODUCTS OF
GALVANIC BATTERIES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to improvements in utilization and regeneration of bye
products of Galvanic Batteries and consists in novel and improved means of
treating the residues or bye products of Galvanic Batteries and especially of those
which have an alkaline solution for exciting liquids.
In such batteries the alkaline solution will dissolve the zinc oxide which is
formed in the Battery during action into what is called zincate alkaline. In time
these solutions become saturated with zinc oxide and ought to be replaced by a
fresh exciting liquid or liquids. To reduce the cost of working such batteries i.e. to
render the production of electricity even profitable, I propose to treat the said
zincate alkaline solution or residues in the following ways viz:-
(1) By the addition of water at a suitable temperature and under suitable pressure
with or without salts or oxides or acids or other chemical composition or mixture
of them. By this operation zinc oxide in hydrate or anhydrate state will be
thrown as precipitiate which can be used as a pigment. The remaining solution
will contain more weak solution or alkali or its salts or combinations. By any
suitable means or process this can be converted into a strong solution of alkali
which can be used again in batteries or even the said alkali or salts can be obtained
in solid state.
(2) By freezing, roasting, drying or otherwise solidifying and melting (or either
of these processes) in proper manner by heat or otherwise and then by a subse-
quent treatment of the said residues by water (with or without the addition of
other substances to it) of suitable temperature and under necessary pressure,
I obtain a solution of caustic alkaline metal or salts of it which can be treated and
used afterwards as desired.
(3) By sending under suitable conditions and temperature, a current of a gas or
gases or vapours of the bodies such as iodine bromine chlorine fluorine or any
mixture of them. I shall convert the alkaline of said residues i e. zincate alkaline
into valuable salts of the said alkali such as chlorates, chlorides bi or per iodates
and such like, the air steam or other gases or vapours may be added to the said
gases or vapours in any desirable proportions, instead of using the said bodies in
their gaseous state they may be used separately or combined or even mixed with
other substances in any other form solid or liquid or in their chemical combinations
or salts. The oxides or chlorides iodides and such like of the metals or their
equivalents can be converted into previous state by sending a current of air oxygen
chlorine, or other above mentioned gases or vapours of the bodies or solution of the
same or their salts or combination or by additions to these or by additions to them
of such like substance in a solid or liquid state (either of these processes separately

page_text: or together or in combination with the above mentioned process can be applied
or used for similar purpose in any other forms of batteries.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Improvements in utilization and regeneration of bye products of Galvanic
Batteries substantially as described herein.
