          Appeal No. 95-4515                                                          
          Application No. 08/243,000                                                  

          material or vane using a jet of air 79.  In contrast, the                   
          record before us is devoid of any argument by the examiner                  
          addressing this limitation.  The examiner's answer does not                 
          address this limitation.  Furthermore, we find no teaching in               
          either Hopper or Hansen for the claimed process step, or a                  
          mechanism or rationale for providing said procedural step.  In              
          the absence of a teaching thereof, the examiner has failed to               
          establish a prima facie case of obviousness.                                







                                      DECISION                                        
               The rejection of claims 122, 124, 129, 130, 133 - 143,                 
          145, and 146 is reversed.                                                   
                                      REVERSED                                        







          John D. Smith                   )                                           

                                          8
