An Improved Fluid, and Process of Manufacturing same, for Impreg-
nating Bodies or Suitable Fabrics, Threads, Fibres, or the like,
for Incandescent Lighting Purposes.
I, BODO PUCHMÜLLER, of 18, Brunhildstrasse, Schoeneberg, near Berlin, in the
Empire of Germany, Merchant, do hereby declare the nature of this invention
to be as follows:
1
This invention relates to an improvement in the fluid described in the Specifica-
tion of my previous Patent No. 3811/97 for impregnating bodies or suitable
fabrics, threads, fibres or the like for incandescent lighting purposes.
The present improvement consists in adding to the oxides or nitrates of strontium
and zirconium and the light giving oxides in the process of preparing the fluid
set forth in the Specification of my aforesaid Patent, the oxides or nitrates of barium
and. aluminium, the process and fluid in other respects remaining the same.
Oxide of barium when used alone only produces an ash which falls to pieces
at the slightest touch, and oxide of aluminium if used alone would melt during
the burning off in a pressure gas flame to the complete destruction of the skeleton.
By the combination of the oxides or nitrates of barium and aluminium with the
other ingredients set forth in my previous Patent, however, a fluid is obtained
by means of which fibres, fabrics or the like impregnated therewith and
burnt off after being dried are converted into an incandescent body skeleton or
mantle of great durability and light giving properties.

1, BODO PUCHMÜLLER, of 18, Brunhildstrasse, Schoeneberg, near Berlin, in the
Empire of Germany, Merchant, 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:-

page_text: tion of my previous Patent No. 3811/97 for impregnating bodies or suitable
fabrics, threads, fibres or the like for incandescent lighting purposes.
The present improvement consists in adding to the oxides or nitrates of strontium
and zirconium and the light giving oxides in the process of preparing the fluid
set forth in the Specification of my aforesaid Patent, the oxides or nitrates of barium
and aluminium, the process and fluid in other respects remaining the same.
Oxide of barium when used alone only produces an ash which falls to pieces
at the slightest touch, and oxide of aluminium if used alone would melt during
the burning off in a pressure gas flame to the complete destruction of the skeleton.
By the combination of the oxides or nitrates of barium and aluminium with the
other ingredients set forth in my previous Patent, however, a fluid is obtained
by means of which fibres, fabrics or the like impregnated therewith and
calcined after being dried are converted into an incandescent body skeleton or
mantle of great durability and light giving properties.
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. In the manufacture of a fluid for impregnating bodies or suitable fibres
or the like, for incandescent lighting purposes, by the process set forth in my
previous Patent No. 3811/97, the addition to the oxides or nitrates of strontium
and zirconium and the light giving oxides in the said process, of the oxides or
nitrates of barium and aluminium, as herein before set forth.
2. An improved fluid for impregnating bodies or suitable fabrics, fibres or the
like for incandescent lighting purposes, consisting of a solution of the oxides or
nitrates of strontium, zirconium, barium and aluminium, with the addition of
light giving oxides, substantially as hereinbefore set forth.
