          Application No. 09/065,143                                                  


                               APPEALED SUBJECT MATTER                                
               According to appellants (Brief, page 3):                               
               None of the claims will be argued separately.  Claims                  
          8 and 11-13 therefore stand or fall together.                               
          Accordingly, for purposes of this appeal, we select claim 8 from            
          all of the claims on appeal and determine the propriety of the              
          examiner’s rejections based on this claim alone pursuant to                 
          37 CFR § 1.192(c)(7) and (c)(8)(2000).  Claim 8 is provided                 
          below:                                                                      
                    8.   A device for producing foam materials from two-              
               component reactive plastics comprising two reactive                    
               components using carbon dioxide under pressure, comprising a           
               mixing apparatus for mixing the two reactive components,               
               wherein at least one of the two reactive components contains           
               carbon dioxide under pressure, wherein said mixing apparatus           
               comprises an outlet and at the outlet of this mixing                   
               apparatus at least one exit opening extending to less than 1           
               mm in at least one cross-sectional dimension, wherein said             
               device also comprises a sieve to stabilize the flow                    
               immediately downstream of the at least one exit opening                
               extending to less than 1 mm in at least one cross sectional            
               dimension, wherein each said at least one exit opening                 
               comprises a free cross-sectional area, wherein the sieve               
               comprises a free cross-sectional area which is 5 to 100                
               times that of the free cross-sectional area of all of said             
               at least one exit openings.                                            
                                                                                     
                                      PRIOR ART                                       
               The examiner relies on the following sole prior art                    
          reference:
