              Appeal No. 2006-1653                                                                 Παγε 6                                       
              Application No. 09/840,434                                                                                                        


                     We do not find this argument persuasive because Aydelott does disclose low                                                 
              profile protrusions on the sprocket that are formed by two flat surfaces (see the portion                                         
              of the sprocket above A in Figure 3).                                                                                             
                     In view of the foregoing, we will sustain the examiner’s rejection of claims 7                                             
              and 8.                                                                                                                            
                     In summary:                                                                                                                
                     The examiner’s rejection of claims 1 to 4 is not sustained.  The examiner’s                                                
              rejection of claims 5 through 9 is sustained.
