          Appeal No. 2000-1492                                                        
          Application No. 09/255,276                                                  


          member.  Each end member includes radially projecting lugs 18,              
          20 that are received in notches 22, 24 in the core member to                
          facilitate the transmission of torque and axial pressure from               
          the end member to the core member (column 3, lines 55-57).  In              
          addition, the inner annular surface of the end member includes              
          notches 26, 28, 30, 32, the purpose of which is to engage a                 
          key on a chuck (column 2, lines 1-16; column 4, lines 60-64).               
          Accordingly, rotational movement of the chuck can be imparted               
          to the end member and thence to the core member.                            
               Bushell relates to a paper tube 3 having plastic end ring              
          supports 7, 9.  As can be seen from a review of the drawing                 
          figures, especially Figure 2, the paper tube and end rings are              
          constructed such that the tube and end ring assembly has a                  
          uniform inside diameter and a uniform outside diameter.  As                 
          explained at column 1, lines 21-27, heavy gauge tubes of this               
          type may be used to wind yarn or cloth, or for holding heavy                
          items such as carpeting.  These heavy gauge tubes “are usually              
          supported on mandrels so that the product can be loaded onto                
          the tube or removed from the tube” (column 1, lines 27-30).                 
               Looking at the examiner’s § 103 rejection from the                     
          perspective of Kewin as the starting point of the rejection,                
                                          3
