          Appeal No. 2000-1983                                                        
          Application No. 08/990,038                                                  

          wherein said velocity of said main body air vortex is also                  
          selected to enable said main body air vortex to urge said thin              
          liquid film and said film-stripped part of said target material             
          to flow to said liquid outlet means.                                        
               The examiner relies on the following references:                       
          Hibshman       2,847,083                        Aug. 12, 1958               
          Grantham       4,015,957                        Apr. 05, 1977               
               Claims 1, 9, 28 and 31 stand rejected under 35 U.S.C. 103 as           
          unpatentable over Grantham in view of Hibshman.                             
               Reference is made to the briefs and answer for the                     
          respective positions of appellants and the examiner.                        

                                       OPINION                                        

               It is the examiner’s position that Grantham teaches a                  
          particulate extractor for an air stream, including a main,                  
          fiberglass, body 24 with air and liquid inlet and outlet means,             
          with the liquid being recycled.  However, because the reference             
          does not refer to a “thin liquid film,” on the surface that                 
          provides for stripping, the examiner turns to Hibshman for a                
          suggestion, at column 3, lines 5-10, “that a cyclone wall results           
          in liquid forming on the cyclone wall, necessarily leading to               
          stripping” [Final rejection-Paper No. 13-page 2].                           
                                         -3–
