vood pulp.
Snow or pulp paper produced as described can be used for a variety of purposes
f which the following are given merely as examples :-
It is specially suitable for filtering purposes, either as it is, or in the form of
astilles or pieces of any other desired shape produced by pressure and agglomeration
the dry state. It may if desired be diluted or moistened in the liquids to be
Itered before these liquids pass into the strainer or filter.
dapted for use in all those industries in which nitro-celluloses are employed,
It is also particularly
specially for the manufacture of collodion, and celluloid, and in the manufacture
f explosives. The nitrification of my product is effected more regularly and more
uickly than that of the materials ordinarily employed such as cigarette-paper
otton-wool or wadding.

A New Product Obtained from Paper or Pulp, applicable for Use as a
Filtering Material, and in the Manufacture of Celluloid, Collodion,
and Explosives, and for other purposes.
I, ALBERTINE GRANDJEAN, of 108 Boulevard Arago, Paris, France, Work-
woman, 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 :-
This invention has reference to the manufacture of

I designate snow paper," or snow pulp,"
," which I produced by disintegrating
paper containing no size, such as filtering paper or cigarette paper, or paper pulp
before the same is rolled and made into sheets. My new product may also be
produced by disintegrating rinsed or washed and dried pulps, such as rag pulp, and
wood pulp, hereinafter included in the expression paper pulp.
Snow paper or snow pulp produced as described, can be used for a variety of
purposes of which the following are given merely as examples. It is specially
suitable for filtering purposes, either as it is, or in the form of pastilles or pieces of
any other desired shape produced by pressure and agglomeration in the dry state.
It may if desired be diluted or moistened in the liquids to be filtered, before these
liquids pass into the strainer or filter. It is also particularly adapted for use in
alf those industries in which nitro-celluloses are employed, especially for the
manufacture of collodion, or celluloid, and in the manufacture of explosives. The
nitrification of my product is effected more regularly and more quickly than that
of the materials ordinarily employed such as cigarette-paper, cotton-wool or
wadding.
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 :-
The new product herein termed snow paper or snow pulp, produced by disinte-
grating paper containing no size, or any kind of paper pulp before the same is
rolled or made into sheets, as herein set forth.
