          Application No. 08/261,523                                                  


               A rejection not referred to in an examiner’s answer is                 
          assumed to have been withdrawn.  Ex parte Emm, 118 USPQ 180,                
          181 (Bd. Pat. App. & Int. 1958) (citing Ex parte Charch, 102                
          USPQ 363, 364 (Bd. Pat. App. & Int. 1954) and Ex parte Hill,                
          93 USPQ 45, 46 (Bd. Pat. App. & Int. 1952)).  In the                        
          subsequent and final examiner’s answer, viz., the Second                    
          Supplemental Examiner’s Answer (Paper No. 19), the examiner                 
          neither repeats nor references the rejection under 35 U.S.C. §              
          112, ¶ 1.  He only discusses the obviousness rejection                      
          therein.  Therefore, we conclude that the rejection under 35                
          U.S.C. § 112, ¶ 1 has been withdrawn.                                       


               Considering the rejection on its merits arguendo,                      
          however, we note that the term “simultaneously” has been                    
          deleted from the claims.  (Paper No. 18 at 2-4.)  Because the               
          rejection was based on the addition of the term to the claims,              
          its deletion renders the rejection moot.  Next, we address the              
          obviousness of the claims.
