          Appeal No. 98-0455                                                          
          Application 08/467,247                                                      



          USPQ 561, 563 (CCPA 1982); In re Marzocchi, 439 F.2d 220, 224,              
          169 USPQ 367, 370 (CCPA 1971).  Once this is done, the burden               
          shifts to the appellant to rebut this conclusion by presenting              
          evidence to prove that the disclosure in the specification is               
          enabling.  See In re Doyle, 482 F.2d 1385, 1392, 179 USPQ 227,              
          232 (CCPA 1973), cert. denied, 416 U.S. 935 (1974); In re                   
          Eynde, 480 F.2d 1364, 1370, 178 USPQ 470, 474 (CCPA 1973).                  


                    In the case before us, we believe the examiner has                
          not met his burden of advancing acceptable reasons                          
          inconsistent with enablement.  While we appreciate the                      
          examiner's discomfiture over the somewhat schematic                         
          illustration of the parts loading system in appellants’                     
          drawings, and the paucity of details concerning the mechanism               
          by which the flip doors (92) and frame members (91) are                     
          pivoted in the manner set forth on pages 7 and 8 of the                     
          specification, we nonetheless do not find that this issue is                
          such as to give rise to non-enablement when the disclosure as               
          a whole is viewed from the perspective of one of ordinary                   
          skill in the art.                                                           

                                          6
