                                 DECISION ON APPEAL                                   
               This is a decision on appeal from the final rejection of               
          claims 1 through 28 and 37 through 44.  Claims 29 through 36                
          have been withdrawn from consideration as being directed to a               
          non elected invention (paper no. 7).                                        
               Appellants' invention relates to a fluorescent lamp in                 
          which mercury is vaporized during lamp operation.  As the                   
          operating temperature increases, the mercury vapor pressure                 
          increases and the efficiency of the lamp is reduced.  There
