                                    THE REJECTION                                     
               Claims 10-28 stand rejected under 35 U.S.C. § 103 as                   
          being unpatentable over Arkens in view of Welch.                            
                                       OPINION                                        
               We have carefully considered all of the arguments                      
          advanced by appellants and the examiner and agree with                      
          appellants that the aforementioned rejection is not well                    
          founded.  Accordingly, we reverse this rejection.                           
               Arkens discloses a method for making a heat resistant                  
          nonwoven fabric (col. 1, lines 5-7).  The heat resistant                    
          fibers used to make the fabric are “fibers which are                        
          substantially unaffected by exposure to temperatures above                  


          of this invention, but may be used in addition to the fixed                 
          base; they do not contribute to the required degree of                      
          neutralization by a fixed base” (specification, page 12, lines              
          22-26).
