          Appeal No. 1998-0982                                       Page 5           
          Application No. 08/399,715                                                  


          that the examiner has not cited any authority for extending the             
          Boesch principle concerning changes in a variable to a                      
          situation in which an apparatus has been structurally modified              
          to achieve a certain result.                                                
               The examiner’s decision rejecting appealed claims 1                    
          through 20 is therefore reversed.                                           
               This application is herewith remanded to the examiner to               
          review the claimed subject matter for compliance (a) with the               
          description requirement in the first paragraph of 35 U.S.C. §               
          112 and (b) with the second paragraph of 35 U.S.C. § 112.                   
               With regard to the first paragraph of § 112, certain                   
          limitations in claim 1 appear to lack descriptive support in                
          the original specification, the original claims or the original             
          drawings.  In particular, appellant’s application as filed                  
          lacks descriptive support for the recitation in claim 1 that                
          the axial stops (in the plural) are “frictionally engageable                
          with the driving wheel.”  Of the two axial stops described in               
          the original specification and shown in the original drawings,              
          namely the control shaft flange 11 and the stop ring 12, only
