          Application No. 08/058,453                                                  

               1.  A method for analyzing concrete, comprising:                       
               transmitting a first microwave signal having a first                   
          frequency that is directed to concrete being tested having                  
          unknown water and cement proportions;                                       
               receiving a reflected microwave signal resulting from at               
          least portions of said transmitted microwave signal being                   
          reflected by the concrete;                                                  
               providing a first value related to a reflection                        
          coefficient for a concrete sample having known water and                    
          cement proportions;                                                         
               obtaining a second value related to a reflection                       
          coefficient based upon at least said reflected microwave                    
          signal from the concrete being tested;                                      
               determining a difference magnitude related to a                        
          difference between said first value and said second value;                  
               having analysis information related to correlating said                
          difference magnitude and one of a plurality of strength                     
          related values for the concrete being tested; and                           
               determining a strength related value for the concrete                  
          being tested using said difference magnitude and said analysis              
               The reference relied upon by the examiner as evidence of               
          obviousness is:

          IECI-19, No. 4, pp. 120-125 (November 1972).                                
               Appealed claims 1 and 8 stand rejected under 35 U.S.C.                
          103 as being unpatentable over Rzepecka.
