          Appeal No. 1997-2036                                                        
          Application No. 08/335,991                                                  


          group and provides arguments as to the separate patentability               
          of each group in accordance with 37 CFR  1.192(c)(7).                      
          Therefore, we will treat the claims as falling into the two                 
          groups proposed by appellant, with claims 1 and 4,                          
          respectively, as representative.                                            
               We have carefully considered the claims, the applied                   
          prior art references, and the respective positions articulated              
          by appellant and the examiner.  As a consequence of our                     
          review, we                                                                  




          will reverse both the anticipation rejection of claim 4 and                 
          also the obviousness rejection of claims 1 through 3.                       
               "It is axiomatic that anticipation of a claim under 102               
          can be found only if the prior art reference discloses every                
          element of the claim,"  In re King, 801 F.2d 1324, 1326, 231                
          USPQ 136, 138 (Fed. Cir. 1986).  See also, Lindemann                        
          Maschinenfabrik v. American Hoist and Derrick, 730 F.2d 1452,               
          1458, 221 USPQ 481, 485 (Fed. Cir. 1984).  In the present                   
          case, claim 4 requires, in pertinent part, a plurality of                   
          buffer chambers with a plurality of connecting channels                     
                                          4
