          Appeal No. 2001-0382                                                        
          Application No. 08/861,481                                                  


               The Examiner relies on the following prior art:                        
          Friesen                            4,873,393      Oct. 10, 1989             
          Newmoyer (Newmoyer ‘071)           5,493,071      Feb. 20, 1996             
          Newmoyer et al. (Newmoyer ‘173)    5,519,173      May  21, 1996             
          Brorein et al. (Brorein)           5,767,441      Jun. 16, 1998             
                                                  (filed Jan. 04, 1996)               
               Claims 2-5 and 8 stand finally rejected as being indefinite            
          under the second paragraph of 35 U.S.C. § 112.  Claims 1-14 and 24          
          stand finally rejected under 35 U.S.C. § 103(a).  As evidence of            
          obviousness, the Examiner offers Brorein in view of Newmoyer ‘173           
          with respect to claims 1-3, 5-11, and 24.  To this basic                    
          combination, the Examiner separately adds Freisen with respect to           
          claim 4, and Newmoyer ‘071 with respect to claims 12-14.                    
               Rather than reiterate the arguments of Appellants and the              
          Examiner, reference is made to the Briefs1 and Answer for the               
          respective details.                                                         
                                      OPINION                                         
               We have carefully considered the subject matter on appeal, the         
          rejections advanced by the Examiner and the evidence of                     
          obviousness relied upon by the Examiner as support for the prior            
          art rejection.  We have, likewise, reviewed and taken into                  

               1 The Appeal Brief (revised) was filed October 3, 2000 (Paper No. 19). 
          In response to the Examiner’s Answer dated November 20, 2000 (Paper No. 20), a
          Reply Brief was filed February 27, 2001 (Paper No. 21), which was acknowledged
          and entered by the Examiner in the communication dated May 2, 2001 (Paper No.
          23).                                                                        
                                          3
