in the direct process of manufacturing iron and steel.*

Claims.—(1.) In the direct process of manufacturing iron
and steel, keeping the slag in the gas or other reverberatory
furnace in the ferrous condition—that is, in a state in which
it contains a minimum of oxygen and is prevented from
absorbing oxygen from the gases of the furnace, thereby pre-
venting any oxidation of the reduced iron by contact with
the slag. (2.) Keeping the slag in a gas or other reverberatory
furnace in the ferrous condition by the addition thereto, or
in contact therewith, of solid carbon or other suitable deoxi-
dizing material, or an admixture of reduced iron and carbon-
aceous or other suitable deoxidizing material, according as to
whether wrought iron or steel is to be manufactured.

No. 21174.—21st May, 1906.—JOHN BRUCE CARROLL,
of 90 Illinois Street, Chicago, Illinois, United States of
America, Engineer. Process of burning acetylene gas and
burner therefor.

Claims.—(1.) An acetylene-gas burner consisting of a body
of refractory heat-insulating material, provided with a supply-
conduit, a recessed flame-chamber, preferably cylindrical,
of sufficient width to admit air around and to the base of the
flame, and a duct, preferably short and in axial alignment
with the flame-chamber, extending from said conduit to said
chamber. (2.) A duplex acetylene-gas burner, each branch
of which has the construction specified in the preceding
claim, the flame-chambers of the two branches being arranged
in opposition. (3.) The process of burning acetylene gas and
maintaining at the orifice a temperature above that which
permits the accumulation of carbon and solid hydrocarbons,
which consists in causing the gas to burn with the base of the
flame at or near the orifice, and heating the air supplied
to the base of the flame specifically by causing the air to move
towards the base of the flame and sheathing the base to re-
tain the heat.
