          Appeal No. 95-1473                                                          
          Application No. 07/997,279                                                  


          activated phosphor only rather than this phosphor in combination            
          with the manganese-activated halophosphate (which generally                 
          corresponds to the here claimed phosphors).  This disclosure not            
          only would have suggested that phosphor suspensions of the type             
          here claimed and disclosed by the Admitted Prior Art and                    
          Westinghouse are different from those of Ropp but also that the             
          beneficial results taught by Ropp to attend use of ammonia                  
          compounds with his phosphor suspensions would not be expected               
          with respect to the suspensions under consideration.                        
               With further regard to this matter, we are aware of the                
          examiner’s position that “this phosphor [i.e., the phosphor                 
          claimed by the appellants and disclosed by the Admitted Prior Art           
          and Westinghouse] contains Sb and Mn activators that are                    
          susceptible to oxidation during lehring, which oxidation would be           
          minimized by the addition of ammonium chloride” (Answer, page 3).           
          However, we find no evidence of record and the examiner points to           
          none which supports the proposition that “Sb and Mn activators              
          ... are susceptible to oxidation during lehring, which oxidation            
          would be minimized by the addition of ammonium chloride.”  In the           
          absence of such evidence, the examiner’s position cannot be                 
          accepted as well founded.                                                   



                                          4
