               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.                                                                          
                                                     8
