          Appeal No. 1996-3162                                                        
          Application 08/227,897                                                      



          filed for:  (a) the recitation in claim 2 that (emphasis                    
          added) "said solid residue is continuously transferred out of               
          said primary oxidation chamber" (only periodic transfer is                  
          disclosed, see specification, page 13, lines 3 and 22), and                 
          (b) the recitation in claim 3 that "said solid residue is                   
          continuously transferred to a device to recover the thermal                 
          energy therein."  This problem appears to have arisen when, in              
          the amendment filed on November 18, 1991, appellants changed                
          the expression "gasified solid organic materials are" in                    
          claims 2 and 3 to --solid residue is--.                                     
          (B) Claim 14 is rejected for failure to comply with 35 U.S.C.               
          § 112, second paragraph.  The scope of this claim is                        
          indefinite, because the recitation therein that the grate is                
          periodically actuated to remove non-combustible solid residue               
          from the primary oxidation chamber is inconsistent with the                 
          recitation in parent claim 2 that the solid residue is                      
          continuously transferred out of the primary oxidation chamber.              




          Conclusion                                                                  

                                          12
