          Interference No. 103,141                                                    

                    Sawada also includes examples in the involved                     
          application wherein the oxide powder in the cladding is first               
          sintered and the cross-section reduction occurs during or                   
          after sintering.  See examples 1 and 2 of Sawada’s                          
                    Counts 2 and 3 read as follows:                                   
                    2.  A method of producing an elongate                             
          superconductive body, characterized in that the method                      

                    (a)  forming an intermediate body comprising a                    
          normal metal cladding surrounding a quantity of oxide powder                
          and in contact therewith;                                                   
                    (b)  forming an elongate body from the intermediate               
          body by means of one or more cross-section-reducing                         
                    (c)  forming at least one orifice through said metal              
          cladding; and                                                               
                    (d)  heat treating the elongate body such that                    
          substantial sintering of the oxide powder occurs, with the                  
          oxide powder being in contact with an oxygen containing                     
          atmosphere by passing oxygen through said at least one                      
          orifice; with the oxygen concentration in the atmosphere such               
          that the thus produced body manifests superconductivity, with               
          T  of 41 K or above, T  being either T (R=0) or T (onset),c                c               c          c                             
          wherein at least the portion of the cladding that is                        
          substantially inert with respect to oxygen and with respect to              
          the oxide powder under the treating conditions.
