Appeal No. 1999-1765 Page 15 Application No. 08/839,193 For the FIG. 5 embodiment, releasable connection of tube 12 to grid 13 is effected by the combination of a threaded sleeve 26 welded to the end of tube 12, a threaded bushing 27, and a nut 28. (Column 3, lines 7- 10; emphasis ours.) And, further states: Installation of the preassembled tube 12, with welded sleeve 26 and shank 21 combination in the FIG. 5 arrangement is accomplished in a similar manner to that described in relation to FIG. 4 insofaras[sic] connection of tube 12 to grid 14 is concerned. The difference between the FIG. 4 and FIG. 5 arrangement lies in the feature that in FIG. 5 there are adjustable connections to both grids 13 and 14. For providing adjustable connection to grid 13, the inside diameter of threaded passage 16A is made somewhat larger than the shoulder 31 outside diameter of sleeve 26. This allows the use of adjustment bushing 27 which serves to set the axial position of tube 12 relative to grid 13. Accordingly, after completing the connection to tube 12 to grid 14, bushing 27 is slipped over sleeve 26 and screwed through passage 16A, and nut 28 is tightened until it bears against the outside end 32 of bushing 27 and draws shoulder 31 to bear against the inside end 33 of bushing 27 to establish the axial location of tube 12 with respect to grid 13. (Column 3, line 41 through column 4, line 5; emphasis ours.) We agree with the examiner in his assessment of Jabsen that sleeve 26, which is welded to tube 12, can be considered part of tube 12. However, it appears that in reading the Jabsen patent the examiner has failed to appreciate thePage: Previous 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 NextLast modified: November 3, 2007
