               Appeal No. 1997-2426                                                                                                
               Application 08/087,849                                                                                              

               35 U.S.C.  103 as being unpatentable over Nakano, Heilmann, and Dowdle, the Appellants argue on                    

               pages 10 and 11 of the brief that there is no proper motivation to combine the teachings of Dowdle with             

               the teachings of Nakano and Heilmann.  We note that the Appellants state that “spring types may not                 

               merely be interchanged without regard to their environment and without regard to the stated problem                 

               that each solves.”  The Appellants point out that the Heilmann helical-type compression springs 24 and              

               25 do not unduly interfere with the loose mounting fit of the synthetic resin holders 20 and 21 and the             

               half cores 18 and 19.  The Appellants additionally note that the two leaf springs 14 and 15 in the                  

               Dowdle device are used to permit the sliding of the core assembly 11, from above, into channel 13 of                

               the frame 10.  The Appellants conclude that it is impermissible to pick and choose various elements and             

               or concepts from several prior art references without regard to the environment of the elements and                 

               without an express or implied suggestion in the prior art.                                                          

                       The Examiner argues on pages 3 and 4 of the answer that Nakano has basically all the structure              

               claimed with the exception of the leaf spring.  Nakano has a notch and positioners 10, 11, 15 and 16;               

               and biasing member 6 or 7 in each case members 2 and 3 holding ferrite member 5. The Examiner                       

               relies on Heilmann to teach separate biasing coil springs 24 and 25 to press the
