         Appeal No. 2005-0242                                                       
         Application No. 09/224,980                                                 

              On page 3 of the brief, appellants state that the claims              
         stand together.  We therefore select claim 15 as representative            
         of the rejected subject matter in this appeal.  See 37 CFR                 
         § 1.192(c)(7)(2003).                                                       
              The examiner relies upon the following references as                  
         evidence of unpatantability:                                               
         Gretzinger et al. (Gretzinger)  4,469,739         Sep. 04, 1984            
         Waldrop et al.  (Waldrop)     5,856,249           Jan. 5, 1999             
         McLarty, III.                5,855,991           Jan. 5, 1999             
         Stumpf et al. (Stumpf)        6,035,901           Mar. 14, 2000            

              Claims 15-21 stand rejected under the judicially created              
         doctrine of obviousness-type double patenting as being                     
         unpatentable over claims 1-3 and 6-8 of Waldrop.                           
              Claims 15-21 stand rejected under the judicially created              
         doctrine of obviousness-type double patenting as being                     
         unpatentable over the claims of McLarty, III. in view of                   
         Gretzinger.1                                                               
              Claims 15-21 stand rejected under 35 U.S.C. § 103 as being            
         obvious over Gretzinger in view of Stumpf.                                 
              Claims 15-21 stand rejected under 35 U.S.C. § 103 as being            
         obvious over Stumpf in view of Gretzinger.                                 
              We have carefully reviewed appellants’ brief, the answer,             
         and the evidence of record.  This review has led us to conclude            
         that the examiner’s rejections are well-founded.                           

                                                                                    
         1 Each of the above-mentioned obviousness-type double patenting            
         rejections is sustained in view of appellants’ indication that a           
         terminal disclaimer will be filed to overcome these rejections.  See       
         page 3 of the Answer.  Upon return of this application to the              
         jurisdiction of the examiner, we call upon the examiner and appellants     
         to handle this issue accordingly.                                          
                                         2
