Process of Treating Earthy Oxides or Earthy Alkalies and Preparing
them for Use in the Manufacture of Mantles for Incandescence
Lighting.
I, VICTOR DAIX, Mining Engineer, of 15, Rue de Richelieu, Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the treatment of ordinary earthy oxides, such as
lime, magnesia, baryta, strontium, and other earthy oxides or earthy alkalies,
with a view to their employment in the incandescent lighting of gas or cam-
bustible vapours.
According to this invention the treatment consist in forming with these
oxides, salts, such as sucrates, saccharates, or other similar combinations, which,
after being baked, leave a carbonaceous residue, that preserves the oxides from
the action of gases and the moisture of the atmosphere. Under the action of
heat, the sugar, glucose and the like entering the salt, loses its moisture becomes
decomposed, and nothing remains but a carbonaceous residue, in the pores of
which the oxide is lodged, whereby it is rendered insensible to the action of the
moisture and atmospheric vapour, produced by the combustion of gas or com
bustible vapours.
After this baking. I obtain from cotton, flax, hemp or other
tissue impregnated with these salts, a frame or skeleton, which supports the
metallic oxide, lime, baryta, and the like and forms a very strong mantle.
To these sucrates ordinary earths may be added, sucrates, glucates, butyrates,
amidonates, etc., oxides of rare earths: Yttrium, thorium, zirconium, etc.
according to the colouring desired for the incandescent body.
In order to further strengthen the incandescent body I cover wires made of
platinum, nickel, aluminium, with these salts, or with asbestos in a naked state
or wrapped in cotton, flax or hemp fibres.

Process of Treating Earthy Oxides or Earthy Alkalies and Preparing
them for Use in the Manufacture of Mantles for Incandescence
Lighting.
I, VICTOR DAIX, Mining Engineer, of 15, Rue de Richelieu, Paris, in the
Republic of France, do hereby declare the nature of this invention and in what
Process of Treating Earthy Oxides or Earthy Alkalies and Prépäring
them for Use in the Manufacture of Mantles for Incandescence
Lighting.
I, VICTOR DAIX, Mining Engineer, of 15, Rue de Richelieu, Paris, in the
Republic of France, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
--
This invention relates to the treatment of ordinary carthy oxides, such as
lime, magnesia, baryta, strontia, and other earthy oxides or earthy alkalies,
with a view to their employment in the incandescent lighting of gas or com-
bustable vapours.
According to this invention the treatment consists in combining the oxides
with sugar, glucose or other combinations containing carbon to form sucrates,
glucates or other similar combinations, which, after being burnt leave a car-
bonaceous residue, that preserves the oxides from the action of gases and the
moisture of the atmosphere. Under the action of heat, the sugar, glucose and
the like entering the salt, loses its moisture, becomes decomposed, and nothing
remains but a carbonaceous residue, in the pores of which the oxide is lodged,
whereby it is rendered insensible to the action of the moisture and atmospheric
vapour produced by the combustion of gas or combustable vapour. I obtain
from cotton, flax, hemp, or other fabric, a hood or mantle which I impregnate
with a solution of these salts. The hood or mantle is then dried and fired in the
usual way and leaves a frame or skeleton, which supports the metallic oxide,
lime, baryta and the like and forms a very strong mantle.
To these sucrates of ordinary earths, may be added oxides of rare earths:
yttrium, thorium, zirconium, etc., according to the colouring desired for the
incandescent body.
In order to further strengthen the incandescent body I cover wires made of
platinum, or aluminium, with these salts, or with asbestos in a naked state
or wrapped.in cotton, flax or hemp fibres.
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:
The process described for enabling ordinary earthy oxides or earthy alkalies
to be employed in connection with incandescent lighting by gas or inflammable
vapours, consisting in forming with the oxides or alkalies organic compounds,
such as sucrates, glucates, butyrates, amidonates and the like, which, after
being burned, leave a porous carbonaceous residue, then impregnating with a
solution of the compounds a frame or skeleton made of some textile material
or of an asbestos tissue, or again, of a metallic tissue enveloped in textile
material and then drying and finally firing it.
Dated this 12th day of February 1900.
