PROVISIONAL SPECIFICATION.
Improvements in Apparatus used in the Production of Carburetted
Gas.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from La Société Anonyme des Fontaines à Gaz of
Fontaines-sur-Saône, in the Department of Rhône, in the Republic of France)
to be as follows:-
-
"
This invention is applicable to that class of apparatus called " gas fountains
or to analogous apparatus, in which a current of air becomes charged with car-
buretted vapours by passing through a can or receiver containing matters which
have absorbed carburetting liquids. Hitherto these absorbent materials con-
sisted of a special wood cut into blocks of various shapes.
The inventors have discovered that paper pulp (wood, vegetable or rag cellu-
lose) used alone or agglomerated with various agglutinants such as gum, dextrine,
glucose &c. may constitute a kind of absorbent material superior to those already
employed for this purpose. The advantages which it presents over these are
the following:-
1. Price only slightly above that of the raw material.
2. Facility of moulding the pulp into various shapes, (pellets, blocks, prisms
&c.) and of giving it various densities.
3. Considerable absorbent power and absorption infinitely more rapid than
that of wood. One hour suffices to obtain the maximum absorption whilst with
wood 6 or 7 hours are required.
The paper pulp (wood, vegetable or rag cellulose) is soaked in water only
or in water containing agglutinant matters, then moulded into pellets for exam-
ple, of various dimensions.
On account of their spherical form, these latter may be poured into the receiver
without any precaution to assure the circulation of air, the form of the pellets
favoring the passage of air through the can or receiver. The size of the pellets
and their state of compression may vary.
The paper pulp may also be moulded in the form of blocks of prismatic or
even cubic shape, of various dimensions, in which there will be formed in the
moulding on one of the faces only, one or more small projections of slight
elevation, for the purpose of leaving a small space between the blocks when they
are juxtaposed, so that air may be able to circulate freely between them.
In lieu of employing pellets, blocks. prisms, cubes, &c., a single block of
the same dimension as the interior of the receiver can be emploved, in which
a series of longitudinal and transverse channels have been made to facilitate
the circulation of air through this mass.

(a communication to me from La Société Anonyme des Fontaines à Gaz of

and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
"

or to analogous apparatus, in which a current of air becomes charged with car-
buretted vapours by passing through a can or receiver containing matters which
have absorbed carburetting liquids. Hitherto these absorbent materials con-
sisted of a special wood cut into blocks of various shapes.

Jose) used alone or agglomerated with various agglutinants such as gum, dextrine,
glucose &c. may constitute a kind of absorbent material superior to those already
employed for this purpose. The advantages which it presents over these are
the following:
:―
1. Price only slightly above that of the raw material.
2. Facility of moulding the pulp into various shapes, (pellets, blocks, prisms
&c.) and of giving it various densities.
3. Considerable absorbent power and absorption infinitely more rapid than
that of wood. One hour suffices to obtain the maximum absorption whilst with

The paper pulp (wood, vegetable or rag cellulose) is soaked in water only
or in water containing agglutinant matters, then moulded into pellets for exam-

and their state of compression may vary.

In lieu of employing pellets, blocks, prisms, cubes, &c., a single block of
the same dimension as the interior of the receiver can be employed, in which
a series of longitudinal and transverse channels have been made to facilitate
the circulation of air through this mass.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is: :―
1. An absorbent material consisting of paper pulp (wood or rag cellulose) in
any of its forms, to serve as an absorbent material for liquids employed in the
carburation of air in various kinds of carburetting apparatus substantially as
herein set forth.
2. An absorbent material consisting of paper pulp (wood or rag cellulose) in

page_text: any of its forms, moulded into convenient form for use in various kinds of car-
buretting apparatus, substantially as herein set forth.
3. An absorbent material consisting of paper pulp (wood or rag cellulose) in
any of its forms combined with an agglutinant and moulded into convenient
form for use with various kinds of carburetting apparatus, substantially as
herein set forth.
