          Appeal No. 96-1883                                                          
          Application 08/078,380                                                      


                       The Rejection Under 35 U.S.C.  102(b)                         
               Anticipation is established only when a single prior art               
          reference discloses, expressly or under the principles of                   
          inherency, each and every element of the claimed invention.  See            
          RCA Corp. v. Applied Digital Data Systems, Inc., 730 F.2d 1440,             
          1444, 221 USPQ 385, 388 (Fed. Cir.), cert. dismissed sub nom.,              
          Hazeltine Corp. v. RCA Corp., 468 U.S. 1228 (1984).  A reference            
          anticipates a claim if it discloses the claimed invention such              
          that a skilled artisan could take its teachings in combination              
          with his own knowledge of the particular art and be in possession           
          of the invention.  In re Graves, 69 F.3d 1147, 1152, 36 USPQ2d              
          1697, 1701 (Fed. Cir. 1995), cert. denied, 116 S.Ct. 1362 (1996),           
          quoting from In re LeGrice, 301 F.2d 929, 936, 133 USPQ 365, 372            
          (CCPA 1962).                                                                
               The appellants have set out two arguments with regard to the           
          rejection of claim 1 as being anticipated by Whelan.  Both of               
          these are based upon the appellants’ belief that the holes (148,            
          150, 152 and 154) which exhaust onto the working surface are                
          simple cylinders, which are not at an angle to the working                  
          surface (Replacement Brief, page 6).  We do not agree.  Not only            
          are these holes illustrated in the drawings as being at an angle            
          (Figure 5), but they are described in Whelan’s claim 1 as being             
                                          6
