          Appeal No. 96-2551                                                          
          Application 08/037,767                                                      

          magnitude of the secondary pulse of the first polarity and the              
          first magnitude."  This "wherein" clause describes the effect of            
          activating the "first controlled switch [Q3] in response to the             
          development of a secondary pulse of the first [i.e., negative]              
          polarity and the first magnitude."  The examiner contends the               
          passage in question is "not understood" because                             
                    [i]t is not seen possible that either the "first                  
                    capacitor" or the "second capacitor" can discharge.               
                    When either a positive or a negative pulse is provided            
                    from the secondary winding (turning on either Q3 or Q4,           
                    respectively), a positive voltage is provided between             
                    nodes 30 and 32 due to rectifier [diodes] D1-D4 and               
                    diodes D5 and D6.  With a positive voltage being applied          
                    across nodes 30 and 32, and thus across the "first                
                    capacitor" and the "second capacitor," the "first                 
                    capacitor" cannot discharge.  [Answer at 7; emphasis in           
          This analysis ignores the fact that the diodes do not conduct               
          immediately upon receipt of a negative or a positive secondary              
          pulse and turn-on of control transistor Q3 or Q4.  The diodes do            
          not begin to conduct until after some charge has been transferred           
          via Q3 or Q4 between the capacitors and control electrode 24 of             
          transistor Q1.  See the specification at page 3, line 20 to page            
          4, line 7, and page 12, lines 7-8.  The examiner has not                    
          explained, and it is not apparent to us, why appellant's circuit
