          Appeal No. 96-0881                                                          
          Application No. 07/795,908                                                  


          page 14, appellants contend that there is nothing in Storey                 
          that teaches the claimed preliminary steps of "actually                     
          measuring concentrations of components to be combined into a                
          dialysate as well as determining the actual(or desired)                     
          conductivity of the dialysate to result from the combination                
          of components[emphasis added]."  With respect to Babb,                      
          appellants argue that Babb simply assumes that the value of                 
          the concentrate components is that which is found on the label              
          of the containers prior to mixing (brief, page 10). These                   
          arguments by appellants’ counsel lead one to believe that the               
          claimed "determining" steps of appellants’ method involve some              
          quantitative measurement of the concentrates to determine the               
          "actual concentrate components" to solve the prior art problem              
          wherein reliance is placed on data on the labels of the                     
          concentrate which may vary as much as plus or minus five                    
          percent from the actual values.  On the other hand,                         
          appellants’ specification does not describe any actual                      
          measurement to determine "the actual concentration of                       
          individual concentrate components", but instead indicates that              
          the "concentrate components are expressed in terms of the                   
          final nominal diluted concentrations" (i.e., the values on the              
                                          6
