          Appeal No. 98-1458                                        Page 12           
          Application No. 08/499,211                                                  


          claims 18 and 19 dependent thereon, under 35 U.S.C. § 102(b)                
          is reversed.                                                                


          The obviousness issues                                                      
               We sustain the rejection of claims 6 through 9 and 25                  
          under 35 U.S.C. § 103, but not the rejection of claims 10, 13,              
          15, 16, 20 through 24 and 26.                                               


               The test for obviousness is what the teachings of the                  
          applied prior art would have suggested to one of ordinary                   
          skill in the art.  See In re Young, 927 F.2d 588, 591, 18

          413, 425, 208 USPQ 871, 881 (CCPA 1981).
