          Appeal No. 1998-0023                                                        
          Application 08/470,374                                                      


          unpatentable over Miyata in view of Gillner.  Again,                        
          appellants have not specifically argued the examiner’s                      
          combination of Miyata and Gillner, but have instead pointed                 
          out specific limitations in the claimed subject matter that                 
          they believe are not taught or suggested in the applied                     
          references.  More specifically, in arguing independent claims               
          21 and 23 (brief, page 20), appellants have again urged that                
          Miyata does not disclose a two-stage mixer in which the cross-              
          sectional flow area of the second mixer is greater than that                
          of the first mixer and in which the static mixer elements in                
          the second stage are disposed along the  longitudinal axis of               
          the mixer or arranged longitudinally over a length of the                   
          second mixer.  For the same reasons as set forth above                      
          regarding Miyata as applied against independent claim 17, we                
          find these arguments to be unpersuasive of any error on the                 
          examiner’s part here.  Thus, we will sustain the examiner’s                 
          rejection of claims 21 and 23 under 35 U.S.C. § 103.  As a                  
          result of its grouping with claim 23, we view claim 24 as                   
          falling with the independent claim from which it depends and                
          will therefore also sustain the examiner’s rejection of claim               


                                          11
