Process for Enriching Gas of Low Illuminating Power.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Chartered Patent Agent, do hereby
declare the nature of this invention (as communicated to me from abroad by Emil
Pilous, Manager, G. Ottermann & Co., Manufacturers, all of I Schottenbastei 4,
Vienna, and Arthur Michaelis, of IV Theresianumgasse 2A, Vienna, Austria,
Agent,) to be as follows:-
My invention relates to the enrichment or carburetting of gases of low illuminat-
ing power, especially such as are obtained from dry distillation of refuse and waste
or sweepings so as to render them capable of giving flames of great luminosity.
For this purpose I pass the gas to be enriched through a chamber containing
calcium carbide alone or mixed with a hygroscopic salt, preferably an alkaline
carbonate, such as sodium carbonate. The gas passing through the chamber is
by this means enriched by the gases that are only very gradually and uniformly
developed from the calcium carbide, and thus attains an intense illuminating
power.
The gases to be treated may be produced from a single suitable material or from
mixed materials such as coal and refuse or sweepings or they may be produced
separately from different materials and mixed before passing through the calcium
carbide chamber.

Process for Enriching Gas of Low Illuminating Power.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Chartered Patent Agent, do hereby
declare the nature of this invention (as communicated to me from abroad by Emil
Pilous, Manager, G. Ottermann & Co., Manufactures, all of 1 Schottenbastei 4,
Vienna, and Arthur Michaelis, of IV Theresianumgasse 2A, Vienna, Austria,
Agent,) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention relates to the enrichment or carburetting of gases of low illuminat-
ing power, especially such as are obtained from dry distillation of refuse and waste
or sweepings, sewage matter, petroleum, oil and wood residues coal and other

page_text: organic residuous and waste products suitable for gasefaction so as to render them
capable of giving flame of great luminosity.
For this purpose I pass the gas to be enriched through a chamber containing
calcium carbide either alone or mixed with a hygroscopic salt, preferably an alkaline
carbonate such as sodium carbonate.
The proportions of the mixture of calcium carbide with the sodium carbonate are
not definitely fixed; it is of advantage to take 3 parts of calcium carbide to 5 parts
of sodium carbonate or other hygroscopic salt. The size of the carburator and
the quantity of the mixture or of carbide alone employed for the carburation,
depends upon the quantity of the illuminating gas to be produced and upon the
desired degree of illuminating power.
The carburator is provided with hurdles on which the calcium carbide, or the
said mixture is spread so as to afford as large a surface as possible of the carbide
or mixture for the gas to come in contact with.
The gas passing through the chamber is by this means enriched by the gases
that are only very gradually and uniformly developed from the calcium carbide,
and it thus attains an intense illuminating power.
The gases to be carburated are produced by heating the beforementioned sub-
stances in retorts, either separately or mixed, or the gases may be distilled from
each material separately, and be then mixed together before passing through the
carburator.
The gases are made to pass from the retorts through a hydraulic main into a
condenser, and thence into the carburator, or they may first be passed through the
carburator and then through the condenser.
The lime set free by the decomposition of the carbide constitutes a purifying
medium for the gascous mixture formed in the carburator; the gases after
purification and washing are led into a gas holder where they are stored for
consumption..
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is:-
Process for enriching or carburetting gases of low illuminating power, consisting
in passing the gases produced from house, market, or street refuse or sweepings,
sewage matter, petroleum, oil or wood waste, coal and other organic residuous and
waste products suitable for gasefaction, either before or after purification, into a
carburating vessel containing calcium carbide either alone or mixed with
hygroscopic salts such as alkaline carbonates where the said gases are enriched by
taking up the gas generated very slowly and uniformly from the calcium carbide,
substantially as described.
