          Appeal No. 96-1003                                                           
          Application No. 08/115,791                                                   


               According to the examiner, claims 12 and 21 do not find                 
          descriptive support in the original specification since they                 
          encompass a process wherein the carbonaceous material and                    
          inert particles are separately returned to the reactor.  We                  
          will not sustain this rejection because all that is required                 
          by § 112, first paragraph, is that the claimed subject matter                
          be described in the original specification, and appellant's                  
          specification adequately describes the claimed return of the                 
          separated unreacted carbonaceous material and the separated                  
          inert particles.  The claims do not require that the                         
          carbonaceous and inert materials are separately returned.                    
               We will sustain the examiner's rejection of claims 24 and               
          26 under § 112, second paragraph.  We agree with the examiner                
          that claim 24 is indefinite with respect to whether the                      
          carbonaceous material or inert material has the recited flow                 
          rate of 7.8 6g/second.  While appellant states at page 12 of                 
          the principal brief that claim 24 has a typographical error                  
          "in referencing step (c) rather than step (f)," the examiner                 
          correctly points out that claim 21, upon which claim 24                      
          depends, does not include a step (f).                                        



                                         -5-
