          Application No. 08/796,513                                                  




               Jackson discloses a humidifier for a patient needing                   
          breathing support (col. 1, lines 12-15).  The humidifier (50)               
          comprises a bundle (10) of polysulfone fibers in a chamber                  
          (20)                                                                        
          (col. 3, lines 48-50) having an inlet (21) and outlet (23) for              
          water drawn by pump (P) from reservoir (40) through the space               
          between the fibers with the water maintained at 105º F by a                 
          heater (42) in the reservoir (40).  The humidifier (50) has a               
          plenum (30) for air from a respirator (36) and a plenum (32)                
          for air to the patient (col. 4, lines 4-27).                                


               The appellant's only argument with respect to this ground              
          of rejection is found on pages 6 and 7 of the brief wherein it              
          is argued that "element 42 of Jackson... cannot electrically                
          heat the hollow fibers... all actions taken by element 42 in                
          Jackson are performed on water in reservoir 40.  Element 42                 
          therefore does not electrically heat hollow fibers and can not              
          anticipate the electrical heating means of claim 1."  The                   
          examiner recognizes that Jackson teaches the use of heated                  
          water for heating that is in direct contact with the outer
