Civil Engineer and Patent Solicitor. IMPROVEMENTS IN THE MODE OF PRESERVING
FLOUR." A communication from Adolph Schlieper, of Montreux, in the Republic
of Switzerland.
The Invention consists in preserving flour, or a mixture of various flours, for any
length of time by reducing it to a solid condition in the following way-First it
is in thin layers exposed to the influence of the atmosphere, when it absorbs a
small quantity of moisture; then it is put into moulds made of metal or some
other suitable material and exposed to a pressure, which, according to the fineness
of the grain or the substance of the material, varies up to 100 atmospheres. The
shape and size of the pressed pieces are chosen with regard to the use that is to be
made of them. In the majority of cases the shape chosen is that of a slab, cylinder,
or of a sheaf. Flour, or a mixture of different kinds of flour, either raw or pre-
pared as a strengthening nourishment, may be easily conveyed and kept in the form
acquired by pressure. When it is to be used it is sufficient simply to put some
water to it in order to dissolve it into a homogeneous pap.

CARL KESSELER, of 63, Mohrenstrasse, Berlin, W., in the Empire of Germany,
Civil Engineer and Patent Solicitor. "IMPROVEMENTS IN THE MODE OF PRESERVING
FLOUR." A communication from Adolph Schlieper, of Montreux, in the Republic of
Switzerland.
The Invention consists in preserving flour, meals of all kinds, or a mixture of a
various flours or meals, for any length of time, by reducing it to a solid condition
in the following manner :-First it is exposed in thin layers to the influence of the
atmosphere, when it absorbs a small quantity of moisture; it is then put into moulds
made of metal or other suitable material, and exposed to a pressure which varies up
to one hundred atmospheres, according to the fineness of the grain or the substance
of the material. The shape and size of the pressed pieces are chosen with regard
to their intended use. In the majority of cases the shape selected is that of a
circular or square slab, cylinder, or a sheaf. Flour and ineals of all kinds, or
mixtures of different flours or meals, either raw or prepared as a strengthening
nourishment, may be easily transported and preserved in a so pressed form, and
when required for use it is only necessary to add water, milk, or other convenient
liquid to it in order to dissolve it into a homogeneous pap.-CLAIM.-The process
above described and set forth of forming by strong pressure raw or prepared flour,
or meals of any kind, or mixtures thereof, into solid coherent parts in any convenient
shape, in order to better preserve, pack, and transport the same, as also to render
the same more ready and suitable for consumption.
In witness whereof, I, the said Carl Kesseler, have hereunto set my hand and
seal, this Seventh day of June, A.D. 1879.
