          Appeal No. 1997-3267                                                        
          Application 08/324,386                                                      



          and 6 stand or fall together, that claims 8 and 10 stand or fall            
          together, that claims 9 and 11 stand or fall together and that              
          claims 5 and 7 each stand or fall alone.                                    


                    We will first address the rejection of claims 4                   
          through 6 under 35 U.S.C. § 112, first paragraph.  The examiner             
          objects to the specification as originally filed for failing to             
          provide a basis for “the mixture of liquid and solid materials              
          [being] added into the filter box at a pressure higher than                 
          atmospheric” (answer, page 3).  As a result of the objection, the           
          examiner rejects claims 4 through 6 under 35 U.S.C. § 112, first            
          paragraph, which claims include the limitation of supplying a               
          mixture of liquid and solid materials at higher than atmospheric            
          pressure into the pressure chamber on an upper side of said                 
          filter belt.  The appellant’s argument, in response, is that                
                    one of ordinary skill in the art would                            
                    understand from the specification that the                        
                    mixture for separation is maintained under                        
                    relatively higher pressure both when supplied                     
                    to the pressure chamber and within the                            
                    pressure chamber itself.  The fact that there                     
                    may be other methods of supplying the mixture
