                                  DECISION ON APPEAL                                  
               This is a decision on appeal under 35 U.S.C.  134 from                
          the  rejection of claims 1-9.  We reverse.                                  


                                     BACKGROUND                                       
               The invention at issue in this appeal relates to over-                 
          voltage protection.  Asynchronous inputs and short circuits                 
          generate over-voltage in the windings of generators and                     
          motors.  Over-voltage protection devices use parallel current
