          Application No. 08/513,036                                                  


               Claim 5 stands rejected under the 35 U.S.C. § 103 as                   
          being                                                                       
          unpatentable over Heyen.                                                    
               Finally, all of the appealed claims also stand rejected                
          under the 35 U.S.C. § 103 as being unpatentable over Van NT                 
          Blik in view of Menigaux and Heyen.                                         
               We refer to the brief and reply brief and to the answer                
          for a complete exposition of the opposing viewpoints expressed              
          by the Appellants and by the Examiner concerning the above                  
          noted rejections.                                                           
                                       OPINION                                        
               We will not sustain any of the rejections advanced by the              
          Examiner in this appeal.                                                    
                              THE SECTION 112 REJECTION                               
               It is the Examiner's basic position that the lower limit               
          of  0.25 for the flow ratio range defined by each of the                    
          appealed claims is not supported by the written description of              
          the Appellants' original disclosure as required by the first                
          paragraph of § 112.                                                         
               The test for determining compliance with the written                   
          description requirement is whether the disclosure of the                    
                                          3
