          Interference No. 103,036                                                    



          used herein, and as we understand it to be used in § 1.633, means           

          the burden to establish the proposition at issue by a                       

          preponderance of the evidence.")  The basis for the proposed                

          unpatentability is set forth in Addendum B to the brief.                    

                    The Sterling patent teaches at page 1, lines 19 to 30,            

          a simple device for readily giving the user of a dry cell an                

          approximate indication of the electrical condition of the cell at           

          any time, comprising a cell having ("attached to or, or sent                

          along with [line 25]") an indicating means so that the strength             

          of the cell may be readily tested without the necessity of                  

          hunting up an instrument for the purpose.  Sterling teaches two             

          embodiments.  The first embodiment is depicted in Figures 1 and 2           

          as follows:                                                                 













                                           -22-
