                Before GARRIS, WARREN and TIMM, Administrative Patent Judges.                                                                  

                WARREN, Administrative Patent Judge.                                                                                           
                                                     Decision on Appeal and Opinion                                                            
                         This is an appeal under 35 U.S.C.  134 from the decision of the examiner finally rejecting                           
                claims 1 through 12.1                                                                                                          
                         We have carefully considered the record before us, and based thereon, find that we cannot                             
                sustain any of the grounds of rejection advanced by the examiner in the answer.  With respect to the                           
                ground of rejection of the appealed claims under 35 U.S.C.  112, second paragraph (answer, page 3),                           
                we cannot agree with the examiner’s position that the introductory phrase “[i]n an extruder assembly”                          
                renders the appealed claims indefinite, because we find no basis in the plain language of the appealed                         
                claims, when interpreted in light of appellant’s specification as it would                                                     

                                                                 - 1 -
