                    In reaching our decision in this appeal, we have given                                                                                                
                    careful consideration to appellant's specification and claims, to                                                                                     
                    the applied prior art reference and APA, and to the respective                                                                                        
                    positions articulated by appellant and the examiner.  As a                                                                                            
                    consequence of our review, we have made the determination which                                                                                       
                    follows.                                                                                                                                              


                    In rejecting claims 20 through 22 under 35 U.S.C. § 103(a)                                                                                            
                    on the basis of the collective teachings of the APA and Goetz                                                                                         
                    '379, it is the examiner's position (answer, pages 3-4) that the                                                                                      
                    APA discloses appellant's claimed clamp and conveyor assembly                                                                                         
                    except for the slot having a pair of spaced, central portions                                                                                         
                    having concave walls.  To address this difference the examiner                                                                                        
                    turns to Goetz '379, urging that this patent teaches "clamp                                                                                           
                    sections incorporating first and second side walls with spaced,                                                                                       
                    central portions having concave walls (best illustrated in Figure                                                                                     
                    5)."  From this teaching, the examiner concludes that it would                                                                                        

                                                                                    44
