Appeal No. 1997-0854 Application No. 08/292,846 of forced cooling air urged through the plenum by the fan," which plenum is formed by plates which support the air heaters and reciprocatable tools. The examiner's statement that "the use of any suitable cooling means to effectively maintain the staking tool at a temperature cooler than the solidification point of the studs is considered within the purview of one of ordinary skill in the art" (page 2 of Answer) does not establish the obviousness of the particularly claimed method of cooling the reciprocatable tools in the recited method of hot staking workpieces. We cannot countenance the summary rejection of any and all methods of cooling reciprocatable tools of hot staking processes. We now turn to the remaining claims on appeal which fail to recite any cooling of the reciprocatable tools. In essence, we are in full agreement with the examiner that it would have been obvious for one of ordinary skill in the art to automate the hot staking method of wells, as modified by Loren, to facilitate controlling the air flow, the amount of heat delivered to the thermally softenable studs, and the timing of the reciprocatable tools. We simply find no error in the examiner's reasoning that: -7-Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
