          Appeal No. 98-0007                                                          
          Application 08/440,907                                                      



          art attempting to read the claims in light of the specifica-                
          tion could not determine their scope with any reasonable                    
          degree of precision.  Cf. In re Cohn, 438 F.2d 989, 993, 169                
          USPQ 95, 98 (CCPA 1971).                                                    
          (B) Claim 6 is rejected for failure to comply with the                      
          enablement requirement of 35 U.S.C. § 112, first paragraph.                 
                    Claim 6 recites that “said face plate defines a load              
          bearing surface area to engage with such a flange protruding                
          outwardly from the engine block.”  As discussed above in                    
          rejection (A), there is no detailed description in the                      
          specification of the recited “flange,” and thus there is no                 
          disclosure which would enable one of ordinary skill to provide              
          a load bearing surface on the face plate to engage the flange.              
          The only disclosure of any relevance would seem to be on page               
          8, lines 9 to 12, where it is stated that the fan blade                     
          assembly can be removed and the mounting studs of the fan                   
          blade assembly can abut the confronting surface of the face                 
          plate, but there is nothing in this                                         





                                          6
