 Application No. 09/532,114                                                              



       We reach the same conclusion for the same reasons with respect to independent     

 claims 8 and 14 and dependent claims 10-13, for the independent claims contain the      

 same limitations as were discussed above with regard to claim 6. With regard to claim   

 14, we further point out that the evidence adduced by the examiner does not support     

 the conclusion that the valves and the control mechanism for regulating the flow rate of

 the non-acetylene and acetylene fuels would have been obvious to one of ordinary skill  
          (                                                                              
 in the art for application to the Ikeda system.
