                                  DECISION ON APPEAL                                  
               This is a decision on appeal from the examiner's refusal to            
          allow claims 26-42, which are all of the claims pending in this             
          application.                                                                
                                     BACKGROUND                                       
               Appellant's invention relates to a gas dispersion apparatus.           
          An understanding of the invention can be derived from a reading             
          of exemplary claim 26, which is reproduced below.
