          Appeal No. 97-3210                                                          
          Application No. 08/386,388                                                  


          claim 1 therefore is not found in Redder, and this rejection                
          of claim 1 and, it follows, of dependent claim 2, cannot be                 
          sustained.                                                                  
               The second Section 102 rejection is based upon Ruhe,                   
          which discloses a sealing member for flanged joints.  The                   
          examiner considers metal collar 2 and outer ring 4 to be the                
          primary sealing members and elastic sealing ring 3 to be the                
          secondary seal.  The examiner admits that collar 2 and ring 4               
          are not explicitly disclosed as being sealing members but                   
          concludes “they will and do perform a sealing action, thereby               
          they are seals” (Answer, page 6).  Here, again, the examiner                
          has resorted to speculation in the making of a rejection.                   
          Neither “centering collar portion 2," which is of aluminum,                 
          nor “outer ring 4," which is provided with a gap in its                     
          periphery, are described as performing a sealing function                   
          (column 2).  The only element so described is sealing ring 3,               
          as to which the patent states “the sealing effect is produced               
          by an elastic or plastic deformation of the seal ring 3"                    
          (column 2, lines 56-58).  From our perspective, therefore,                  
          this reference discloses only one sealing element, and thus                 
          fails to anticipate claim 1.                                                
                                          7
