          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 the
