          Application 07/953,539                                                      


          (8) Claims 6, 8 and 9 on the basis of Booth in view of Bellis and           
          Smith.                                                                      
               The rejections are explained in the Examiner's Answer.                 
               The opposing viewpoints of the appellant are set forth in              
          the Brief.                                                                  
                                       OPINION                                        
               We shall consider the ten rejections posed by the examiner             
          in the order in which they appear in the Answer.  The first two             
          are on the basis of anticipation, which is established only when            
          a single prior art reference discloses, either expressly or under           
          the principles of inherency, each and every element of the                  
          claimed invention (see In re Paulsen, 30 F.3d 1475, 1480-1481, 31           
          USPQ2d 1671, 1675 (Fed. Cir. 1994) and In re Spada., 911 F.2d               
          705, 708, 15 USPQ2d 1655, 1657 (Fed. Cir. 1990)).  Claims 1, 2, 9           
          and 12 stand rejected as being anticipated by Domnikov.  These              
          claims all are directed to a waveguide seal assembly comprising             
          an inner conductive part, an outer part, and a gas sealing                  
          element located in a gap between the two other elements.  Among             
          the claim requirements is that the outer part be "separable" from           
          the inner part, and the sealing element "removably" fit in the              
          gap.  The waveguide seal disclosed in Domnikov comprises the same           
          three elements arranged in the same fashion, but they are secured           

                                          4
