                     Claims 2 and 4 through 24 stand rejected under 35 U.S.C. § 103 as being

                     In reaching our decision in this appeal we have given careful consideration to the                    
              appellants' specification and claims and to the respective positions articulated by the                      
              appellants and the examiner.  We make reference to the examiner's answer (Paper No.                          
              52, mailed June 11, 1996) for the examiner's reasoning in support of the rejection and to                    
              the appellants' brief (Paper No. 50, filed March 22, 1996) for the appellants' arguments

                     4Ryser was submitted as an attachment to appellants' "SUPPLEMENTAL RESPONSE AFTER                     
              FINAL REJECTION" filed September 9, 1994 (Paper No. 30).                                                     
                     5In the advisory action mailed April 26, 1996 (Paper No. 43), the examiner stated that the            
              amendment filed December 14, 1995 (Paper No. 42) overcame the final rejection of claims 2 and 4-24 under     
              35 U.S.C. § 112, second paragraph, as indefinite.                                                            
                     6Appellants' reply brief filed August 12, 1996 (Paper No. 55) was denied entry by the examiner in a   
              communication mailed September 30, 1996 (Paper No. 56).  Appellants' subsequent petition to enter the        
              reply brief filed December 2, 1996 (Paper No. 59) was denied by the Office of the Director, Group 1800 in a  
              decision on petition mailed October 14, 1997 (Paper No. 61).  Therefore, appellants' reply brief was not     
              considered in rendering our decision.
