          Appeal 1997-2575                                                             
          Application 08/524,661                                                       

                              the [water in the] calcium carbonate filler              
                              [3].                                                     

                    4.   According to the specification (page 3,                       
          lines 19-21) (emphasis and matter in brackets added):                        
               The correct amount of [ketoximosilane] crosslinker is                   
               determined by the hydroxyl content present from both the                
               silanol on the base polymer [[1] in claim 1 as reproduced               
               supra] and the water content of the filler [[3] in claim                
               1 as reproduced supra].                                                 

                    5.   Accordingly, the language "silanol equivalent"                
          in the language "1.3 moles ketoximosilane per silanol                        
          equivalent in the diorganosiloxane based polymer [1] and the                 
          calcium carbonate filler [3]" is believed to mean "hydroxyl                  
          equivalent."                                                                 

                                 Examiner's rejection                                  
                    6.   The examiner has rejected claims 1-20 as being                
          unpatentable under 35 U.S.C. § 103(a) over Beers, U.S. Patent                
          4,514,529 (1985).                                                            

                                        Beers                                          


                                        - 4 -
