          Appeal No. 95-3184                                                          
          Application 07/981,910                                                      


               which communicates with the face mask A and the                        
               patient’s airway [column 3, lines 55 through 68].                      
               The examiner’s conclusion that Emerson teaches or would have           
          suggested a ventilating method meeting the limitations in                   
          appealed claim 33 requiring the addition in succession of pulses            
          of small volumes of gas to provide successively greater volumes             
          of gas successively increasing in pulsatile form the pressure of            
          the gas in the patient’s airway wherein the successive increase             
          in pulsatile form of the pressure is caused solely by the                   
          successive addition of the small volumes of gas is not well                 
          taken.  While Emerson’s vibration of the column of gas in the               
          patient’s airway would appear to supply to the airway a plurality           
          of pulses of small volumes of gas, it is not apparent, nor has              
          the examiner explained, how these pulses would be  additive in              
          succession to provide successively greater volumes of gas                   
          successively increasing in pulsatile form the pressure of the gas           
          in the airway.  Indeed, Emerson’s teaching that the vibrations or           
          pulses applied to the column of air cause the air to move first             
          in one direction and then in the opposite direction would seem to           
          belie any such conclusion.                                                  





                                          -7-
