Appeal No. 95-1724
Application No. 08/011,604
This is a decision on an appeal from the final rejection
of claims 1 through 16 which are all of the claims remaining
in the application.
The subject matter on appeal relates to an insulated
refractory lined refining chamber for aluminum refining being
adapted for the positioning of a spinning nozzle assembly
therein for the injection of sparging gas into a body of
molten aluminum present in the chamber wherein the improvement
consists essentially of vertical, refractory baffle means
positioned at the floor of and across said refining chamber so
as to be located under a rotor portion of said spinning nozzle
assembly upon placement of said spinning nozzle assembly in
the refining chamber. This appealed subject matter is
adequately illustrated by independent claim 1 which reads as
follows:
1. In an insulated refractory lined refining chamber
for aluminum refining, having side walls and a floor and being
adapted for the positioning of a spinning nozzle assembly
therein for the injection of sparging gas into a body of
molten aluminum present in the chamber during aluminum
refining operations, said insulated refractory lined refining
chamber having no gas inlet means in the side wall thereof,
the improvement consisting essentially of vertical, refractory
baffle means positioned at the floor of and across said
refining chamber, so as to be located under a rotor portion of
said spinning nozzle assembly upon placement of said spinning
