          Appeal No. 1999-0865                                                        
          Application No. 08/468,573                                                  

          set forth in the Briefs along with the Examiner’s rationale in              
          support of the rejections and arguments in rebuttal set forth in            
          the Examiner’s Answer.                                                      
               It is our view, after consideration of the record before us,           
          that the Fessenden reference fully meets the limitations of                 
          claims 57, 58, and 60.  We reach the opposite conclusion with               
          respect to claim 59.  We are also of the view that the Examiner             
          has not established a prima facie case of obviousness with                  
          respect to the 35 U.S.C. § 103(a) rejection of claims 61-68 based           
          on the combination of Keeble in view of Fessenden, Barnes, and              
          Müller.  Accordingly, we affirm-in-part.                                    
               We also use our authority under 37 CFR § 1.196(b) to enter a           
          new ground of rejection of claims 59 and 61-68.  The basis for              
          these conclusions will be set forth in detail below.                        
               Appellants’ arguments in response to the Examiner’s                    
          rejections of the appealed claims are organized according to a              
          suggested grouping of claims indicated at page 3 of the Brief.              
          We will address these arguments accordingly, and will consider              
          the appealed claims separately only to the extent that separate             
          arguments are of record in this appeal.  Any dependent claim not            
          argued separately in the Briefs will stand or fall with its base            

                                          4
