Appeal 2007-0200
Application 10/445,466
oxygen-containing gas blown therethrough to melt skull from the furnace
walls, we conclude that Appellants have not demonstrated that the main
nozzles 36 and 36' of Watkins do not function and are incapable of
functioning as deskulling nozzles and thus have not established error in the
Examiner's rejections. Moreover, the four pairs of auxiliary nozzles 382 of
Watkins, as illustrated in Fig. 4, for example, respond structurally to the first
and second sets of deskulling nozzles recited in claim 1, with the first nozzle
of each pair belonging to the first set of deskulling nozzles and the second
nozzle of each pair belonging to the second set of deskulling nozzles
disposed at a different orientation in the tip relative to the first set. The
rejection of claim 1, and the rejections of claims 2-20, which Appellants
have not argued separately from the rejection of claim 1, are sustained.
2 Appellants do not dispute that auxiliary nozzles 38 or 38' of Watkins are
deskulling nozzles.
