PROVISIONAL SPECIFICATION.
Manufacture of a New Material, applicable as a Non-conductor of
Heat, for Producing Light Receptacles, and for other purposes.
I, HEINRICH RICHARD KNOCH, Manufacturer, of Alt-Chemnitz, in the Kingdom
of Saxony, do hereby declare the nature of this invention to be as follows:-
My invention has for its object, to produce a light and waterproof material, in
the shape of plates, sheets, tubes or cups, which may be used as a non-conductor of
heat and for other purposes.
For this purpose I take paper stuff as made in paper mills from rags, wood, straw
or other fibrous material, or as obtained as a waste product, and treat it in a
mechanical agitator, so as to obtain a thin pulp; subsequently I add small particles
of cork or of nutshells (preferably of the nut called arachishypogaea), as well as
cellulose, tanner's bark, chaff or other light fibrous material, in the proportion of
about 50 parts of paper stuff to 12 parts of the cork or other vegetable matter, and
treat the whole in a kneading machine, while constantly heating, so as to form a
thick mass. The latter is formed into plates, sheets, tubes or vessels of any desired
shape, and subjected to a temperature of 60 to 100 degrees centigrade.
The product thus obtained, is very light, (spec. gravity from 0-2 to 0-24), tough,
and elastic. It is a bad conductor of heat and cannot be destroyed by water.
In some cases, I add to the paper stuff from 2 to
order to produce greater cohesion.
parts of gum tragacanth, in
By adding from 2 to 5 parts of soda solution or other suitable saline solution, the
material may be rendered incombustible.

I, HEINRICH RICHARD KNOCH, Manufacturer, of Alt-Chemnitz, in the Kingdom
of Saxony, 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 :-
My invention has for its object, to produce a light and waterproof material, in
the shape of plates, sheets, or cups, which may be used as a nonconductor of heat
and for other purposes.
For this purpose, I take paper stuff, as made in paper mills from rags, wood,
straw or other fibrous material, or as obtained as a waste product, and treat it
in a mechanical agitator, so as to obtain a thin and hot pulp; subsequently I
add small particles of cork or of certain nutshells, (the shells of arachishypogaea),
or of cellulose, tanner's bark, chaff or other light fibrous material, in the pro-
portion of about 50 parts of paper stuff to 12 parts of the cork (or other
vegetable matter), and treat the whole in a kueading machine, while constantly
heating, so as to form a thick mass. The latter is formed into plates, sheets,
tubes or vessels of any desired shape, and subjected to a temperature of 60 to
100 degrees centigrade.
The product thus obtained, is very light, (spec. gravity from 0-9 to 0-24), tough,

water.

parts of gum tragacanth, in order
By adding from 2 to 5 parts of soda solution or other suitable saline solution, the
material may be rendered incombustible.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of a new waterproof material in the shape of plates, 1
vessels, tubes or moulded articles from paper stuff and the shells of arachishy-
pogaea (or one of the substitutes hereinbefore mentioned) in the manner substan-
tially as described, with or without the addition of gum tragacanth and of soda
solution.
2. A new material composed or produced in the manner substantially as 1
described.
Dated this 7th day of November 1892.
