              Application No. 08/287,056

                     We REVERSE both rejections.                                                                           
                     In reaching our decision in this appeal we have given careful consideration to the                    
              appellant's specification and claims and to the respective positions articulated by the                      
              appellant and the examiner.  We make reference to the examiner's answer (Paper No. 21,                       
              mailed January 18, 1996) for the examiner's reasoning in support of the rejections and to                    
              the appellant's brief (Paper No. 20, filed November 24, 1995) for the appellant's                            
              arguments thereagainst.                                                                                      





                     2 Recitation of "Claims 1-1 and 7-8 are rejected under 35 U.S.C. § 112, first paragraph, ... " on page
              3 of the examiner's answer appears to be an obvious typographical error, with claims 1-2 and 7-8 intended.   
              Moreover, since the final rejection of claims 3-6 under 35 U.S.C. § 112, second paragraph, is not repeated   
              in the answer, it is presumed to have been withdrawn.  Ex parte Emm, 118 USPQ 180, 181 (Bd. App.             
              1957).
