          Application 08/535,850                                                      


          application.                                                                




               Appellants’ invention pertains to a feed nozzle assembly.              
          A basic understanding of the invention can be derived from a                
          reading of exemplary claim 11, a copy of which appears in the               
          APPENDIX to the amended appeal brief (Paper No. 16).                        


               As evidence of obviousness, the examiner has applied the               
          document specified below:

          1992                                                                        


               The following rejection is before us for review.                       


               Claims 1, 11 through 17, and 19 stand rejected under 35                
          U.S.C. § 103(a) as being unpatentable over Nielsen.                         


               The full text of the examiner's rejection and response to              
          the argument presented by appellants appears in the answer                  
                                          2
