I EDOUARD PAUL LOUVOT of 11 Place des Vosges, Paris, Button Manufacturer,
do hereby declare the nature of my said invention for IMPROVED METHOD OF
TREATING DRY ABSORBENT BODIES SUCH AS PAPER, FABRICS, FIBRES AND THE
LIKE FOR THE MANUFACTURE OF MATERIAL SUITABLE FOR VARIOUS USEFUL
PURPOSES," and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The object of my invention is the complete impregnation of the pores of cellulose
with the solid particles of tar in a novel manner and the production of useful
articles therefrom.
For the purpose of my invention I bring into contact with coal, wood or
petroleum tar products composed of cellulose, such as cardboard, paper, rope,
string, thread, stuffs, canvas, dried paper pulp, in a vessel hermetically sealed.
I create a vacuum, the tar settles in the pores of the cellulose from which the air
is removed. I then subject the material to pressure by the aid of steam, com-
pressed air, rolling machines, or hydraulic presses, according to the usage to which
the article is destined.
I then place the material in, say, moulded or stamped sheets in stoves, and by
means of a graduated heat, I extract and collect all the volatile or liquid portions
of the tar, leaving only the solid portions. The material thus treated I call
"Corozine." It is impermeable, uninflammable, acid-proof, imputrefiable, and
capable of numerous applications.
In the form of sheets, as corozined cardboard it forms an impermeable roofing
which besides being light and solid is unaltered by the greatest heat; it is useful
also as partitions for light buildings, and can be used in various ways in building.
It can be stamped into an infinite variety of objects and utensils such as vases,
basons, dishes, and all such articles which are known as boiled leather (cuir bouilli)
or papier-naché products.
It is applicable as barrels for carriage of acids and all other products; pipes for
the conveyance of acids, gas, and of all liquids, by reason of the impermeability of
the material; for panels of carriages, boats, for the different parts of river and

page_text: marine constructions, such are the various applications of Corozine in sheets. In
sheets of paper it may be employed as a covering for protection against damp; for
packing etc.
In the form of a paste compressed by means of the hydraulic press, corozine can
be inade into paving and flagstones for street paving and for flooring factories and
dwelling houses and is particularly valuable in this form for the salubrity of
stables, cattle-sheds, etc.
It can also be used for the manufacture of cart wheels, railroad sleepers, of
bobbins used in spinning, etc, as well as for a great variety of moulded objects used
in different trades and which must possess the qualities of coliesion, impermeability
and the power of resisting heat and acids.
It may be used for moulding paper buttons, mourning jewellery, and similar
articles.
In the treatment of cord, string, and thread, corozine produces sea cables fishing
lines, carriage traces, the various kinds of rope used in building and other trades,
the thread used in harness and boot making, all of which articles are impermeable,
imputrefiable, unimflammable and acid proof.
In the form of cloth, it may be employed for the manufacture of tarpaulins and
waterproof tissues for various usages. In connection with the telegraph trade the
threads and tapes can be used for the casings and braidings of electric cables and
wires.
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
First. A new product formed of cellulose in all its conditions, combined with the
solid portions of tar, which product I call "Corozine."
Secondly. The processes used to obtain it, such as vacuum, pressure, and baking
together with the distillation of the by-products, both volatile and liquid.
Thirdly. The various applications of Corozine in sheets, in paste, in rope, string
and thread, or cloth appropriate to usage in building, in different trades or in the
marine service.
