          Application No. 08/815,747                                                  


               We AFFIRM-IN-PART.                                                     
                                     BACKGROUND                                       
               The appellant's invention relates to a wet gas stripper                
          which utilizes a liquid spray for separating entrained                      
          particulate matter from a moving gas stream (specification, p.              
          1).  A copy of claim 1 under appeal appears in the appendix to              
          the appellant's reply brief (Paper No. 16, filed July 20,                   
          1998).  A copy of claims 3 to 10 under appeal is set forth in               
          the appendix to the appellant's brief (Paper No. 14, filed                  
          April 9, 1998).                                                             


               The prior art reference of record relied upon by the                   
          examiner in rejecting the appealed claims is:                               
          Clark                    2,802,543                     Aug. 13,             
          1957                                                                        



               Claims 1 and 3 to 10 stand rejected under 35 U.S.C. §                  
          112, second paragraph, as being indefinite for failing to                   
          particularly point out and distinctly claim the subject matter              
          which the appellant regards as the invention.
