          Appeal No. 97-1841                                                          
          Application 08/315,052                                                      


          Furthermore, the appellant states that the optical element in his           
          invention is provided to reflect light in a direction back toward           
          the lamp.  This is precisely the disclosure of Palmquist which              
          provides his optical element to reflect light back to the eyes of           
          the driver of the automobile that is illuminating the sign.                 
               For the foregoing reasons, the rejection of the claim on               
          appeal has been affirmed.                                                   
               No time period for taking any subsequent action in                     
          connection with this appeal may be extended under 37 CFR                    
          § 1.136(a).
