          Appeal No. 1999-0527                                                        
          Application No. 08/801,837                                                  

                                       OPINION                                        

               In reaching our conclusion on the issues raised in this                
          appeal, this panel of the board has carefully considered                    
          appellants’ specification, drawing, and claim 1, and the                    
          respective viewpoints of appellants and the examiner.  As a                 
          consequence of our review, we make the determinations which                 
          follow.                                                                     

                The rejection under 35 U.S.C. § 112, first paragraph                  

               We affirm this rejection.                                              

               The rejection questions the adequacy of appellants’                    
          disclosure of their invention as it pertains to the question of             
          whether the disclosure would have enabled one skilled in the art            
          of seal arrangements for shaft ends to make and use the                     
          invention.  The test regarding enablement is whether a                      
          disclosure, as filed, is sufficiently complete to enable one of             
          ordinary skill in the art to make and use a claimed invention               
          without undue experimentation.  See In re Wands, 858 F.2d 731,              
          737, 8 USPQ2d 1400, 1404 (Fed. Cir. 1988) and In re Scarbrough,             
                                          3
