          Appeal No. 1996-3975                                                        
          Application No. 08/328,179                                                  


          diluent.  The tank functions by reducing the pressure, which                
          results in vaporization of monomer and diluent.                             
               The second flash separation means is defined in the                    
          specification at page 6, lines 1-18.  We find the second flash              
          separation means to be a low pressure flash tank 25.  The tank              
          has a conduit means 23 through which it receives a minor                    
          portion of the reaction effluent.  We find that two outlets                 
          are provided from the tank, 27 and 29.  The polymer is removed              
          through conduit 27.  Monomer is removed through conduit 29.                 
          We further find that the means for analyzing, i.e., the                     
          analyzer transducer 33 is connected to an outlet in tank 25                 
          via conduit 29.  The flashing tank 25 typically has a low                   
          capacity of about 2 to about 5 cubic feet.  The tank functions              
          by  vaporization of the monomer and diluent.                                
               Based upon the above interpretations we conclude that                  
          each tank performs a separate and distinct function and                     
          receives                                                                    
          its reaction effluent directly from the reactor.  Accordingly,              
          the claimed subject matter requires the presence of two tanks,              
          a high pressure tank and a low pressure tank arranged in
