                                  DECISION ON APPEAL                                  
               This is a decision on appeal from the examiner's refusal to            
          allow claims 1, 5-9 and 11.  The appeal as to claim 2 was                   
          withdrawn by appellants (brief, page 2).  No other claims remain            
          pending in this application.                                                
               Appellants’ invention relates to a welding apparatus for               
          joining roofing elements.  The apparatus includes a pressure                
          roller and a blower having a nozzle with a particular tripartite            
          outlet construction.  An understanding of the invention can be              
          derived from a reading of claim 1, the sole independent claim on            
          appeal.  Claim 1 is reproduced below:
