                Appeal 2007-1266                                                                              
                Application 10/125,204                                                                        

                      For the reasons discussed below, we answer this question in the                         
                affirmative.                                                                                  
                      III.  The Examiner contends that Schwarzkopf anticipates the claims.                    
                Appellants contend that Schwarzkopf fails to disclose a face seal having a                    
                diameter which is greater than that of the molding chamber.  The issue                        
                before us is:  Has the Examiner properly established that Schwarzkopf                         
                discloses the claimed rigid face seal assembly?                                               
                      For the reasons discussed below, we answer this question in the                         
                affirmative.                                                                                  
                                                                                                             
                                       RELEVANT FINDINGS OF FACT                                              
                      1) According to the Specification, “[a] conventional                                    
                         thermosetting or thermoplastic resin into which the metallographic                   
                         sample is encapsulated is melted under an internal mold pressure                     
                         of from about 2000 psi to about 4200 psi at about 300 oF.”                           
                         (Specification [0021]).                                                              
                      2) The Specification provides that “[t]he body of the mold                              
                         cavity and the cap piece forming the face seal can be made of                        
                         metals typically used for sample mounting presses, such as                           
                         stainless steel, aluminum alloys, or the like.”  (Specification                      
                         [0021]).                                                                             
                      3) The Specification further states that “[t]he sealing surfaces                        
                         28 and 31 of the respective members are polished to form a leak-                     
                         free seal when cylinder 25 is actuated by a pressure of about 3000                   
                         psi.”  (Specification [0021]).                                                       


                                                      4
