Appeal No. 2003-1549
Application No. 09/356,400
appellants (Brief, pages 6-8), Tenner employs its nozzle
arrangement to produce the following effect (column 7, lines 9-19):
each reducing gas injection means will comprise a
plurality of tubes . . . disposed generally parallel and
in the same plane as each other tube . . . a plurality of
apertures or nozzle type openings to facilitate injection
of the reducing gas . . . these openings will be spaced
such that the spray pattern therefrom will slightly
overlap the spray pattern from adjacent openings thereby
substantially blanketing the entire cross-section of
combustion effluent gas flow area.
To supply such spray patterns at the locations where the baffle
described in Mansour is placed would destroy the invention on which
Tenner is based. Ex parte Hartmann, 186 USPQ 366, 367 (Bd. App.
1974). The examiner has not proffered any evidence that the spray
patterns desired by Tenner can be obtained in the environment
taught by Mansour.
