          Appeal No. 1997-0144                                                        
          Application No. 08/424,223                                                  

          absorption, can be laundered at high temperatures conventionally            
          used for industrial fabrics, etc..  Given the nature of the known           
          VECTRAN M fiber vis-a-vis the other normal strength fibers (e.g.,           
          nylon and polyester) for use in the second wrapping (14) of                 
          Bettcher, it is our opinion that it would have been obvious to              
          one of ordinary skill in the art at the time of appellant's                 
          invention to use the normal strength synthetic fiber VECTRAN M as           
          one of the fibers for the second wrapping (14) of Bettcher so as            
          to gain the self-evident benefits thereof relative to the                   
          underlying high strength Kevlar fiber wrapping (12) over which it           
          would be applied.  As for the claims requiring a metal strand in            
          the cut-resistant yarn, we note the disclosure of Bettcher at               
          column 1, lines 46-58, and column 2, lines 51-55.  Bettcher also            
          discloses (e.g., Fig. 2 and col. 4, line 48+) that the composite            
          yarn therein may be formed into protective apparel, such as a               
          cut-resistant protective glove.                                             

          In addition to the foregoing, we REMAND this application to                 
          the examiner to consider whether other rejections of the claims             
          of this application would be appropriate, for example, other                
          prior art rejections on art of record or otherwise, or a                    
          rejection based on 35 U.S.C.  112, first paragraph, that the               
                                         12
