                 Examiner, reference is made to the brief and answer  for the                                3

                                                                     OPINION                                                                            
                          We will not sustain the rejection of claims 19 through 29

                          The Examiner has failed to set forth a prima facie case.

                 ordinary skill in the art would have been led to the claimed                                                                           
                 invention by the express teachings or suggestions found in the                                                                         
                 prior art, or by implications contained in such teachings or

                 June 26, 1996, which we will refer to simply as the answer.                                                                            
                                                                           5
