          Appeal No. 1999-0195                                                        
          Application 08/507,424                                                      


          Cone, claim 1 is anticipated by Cone.                                       
               Claim 16 is rejected 35 U.S.C.  112, second paragraph.                
          In order to satisfy the second paragraph of  112, a claim                  
          must accurately define the claimed subject matter in the                    
          technical sense.  See In re Knowlton, 481 F.2d 1357, 1365, 178              
          USPQ 486, 492 (CCPA 1973).                                                  
               Claim 14, from which claim 16 depends, requires that the               
          wheel block be mounted “for substantially linear movement”                  
          relative to the carriage in a direction substantially                       
          perpendicular to the lengthwise direction of the guide.                     
          Clearly, this claim language is readable on the embodiment of               
          Figure 4, where the wheel block 26 slides linearly in and out               
          of block carrier 36 in a direction substantially perpendicular              
          to the lengthwise direction of guide member 27.  On the other               
          hand, dependent claim 16 requires that the wheel block be                   
          mounted on a carrier that is “pivotally mounted” to said                    
          carriage.  Appellants’ Figure 2 embodiment is illustrative of               
          a device for blocking wheels wherein the wheel block 6 is                   
          pivotally mounted to the carriage 9.  In our opinion, a wheel               
          block like that of appellants’ Figure 2 that is “pivotally                  


                                          8
