          Appeal No. 1998-2606                                                        
          Application 08/446,415                                                      

               Likewise, the features of claim 11 are shown in the                    
          combined teachings and showings of the references as just                   
          explained.  While the showing in Figure 1 of Watkins utilizes               
          spokes as                                                                   
          a means of supporting the outer periphery of the drum 3, the                
          figure 9 showing clearly indicates that a planar type of                    
          flange is contemplated as well.  The integral structure                     
          resulting from the combination of teachings of the references               
          is consistent with the single piece shown of appellants'                    
          attachment hub 138 in Figures 13-15.                                        
               We do not sustain the rejection of dependent claim 12                  
          since there is no indication in the combined teachings of the               
          three references relied upon that the drum 3 of Watkins and                 
          the rotatable disc 30 of Fales have a non-circular cross                    
          section aperture or opening and a corresponding shape in the                
          drive shaft engaging portion of the hub 4 of Watkins for                    
          cooperable engagement of the image disc on the axially                      
          extending drive shaft engaging portion as recited in claim 12               
          on appeal.  We note again that the examiner has not rejected                
          the features recited in claim 13 under 35 U.S.C.  103 which                
          in turn is dependent on claim 12.
