Appeal No. 1997-3089 Page 5 Application No. 08/577,839 The “rings” of King and Allegre appear to be part of a squirrel cage structure which structure, as a whole, acts to reduce vibration. Thus, we agree with appellants that there does not appear to be any reason to dissect these rings from the rest of the squirrel cage structures and use only those rings in Persson to achieve the claimed invention. There clearly is no suggestion in any of these references to make such a modification. Moreover, appellants argue that even if such a combination were to be made, the rings of King and Allegre have no time- varying current induced in them by a rotating flux. Appellants submit sketches and an explanation as to why the rings of King and Allegre have no time-varying current induced in them by a rotating flux [principal brief-pages 29-31] and such explanation appears reasonable to us. The examiner’s response [answer-page 9] is to state that it is a “well-known characteristic of electromagnetic fields that when a rotating magnetic flux penetrates a conductive device the flux induces a time varying current in the device.” However, based on appellants’ explanation, it does not appear that the flux lines would pass through ring 21 in King, for example.
