           Appeal No. 96-4197                                                                      
           Application No. 08/425,261                                                              

                       a measuring end and a distal end, the insertion rod being                   
                       axially aligned for insertion of the measuring end into the                 
                       pipeline through said extending mounting member, the                        
                       stuffing assembly, and the blocking valve, wherein the                      
                       measuring end is capable of supporting a measuring                          
                       mechanism;                                                                  
                             (c)  a laterally extending yoke connected with the                    
                       distal end of the insertion rod having two opposing ends                    
                       aligned with the opposing ends of said mounting member;                     
                             (d)  a pair of parallel hydraulic cylinders, each                     
                       hydraulic cylinder having an elongate cylinder body                         
                       extending toward the pipeline adjacent to and aligned at the                
                       side of the stuffing assembly and blocking valve, a piston                  
                       movably located in each of said cylinders, and a piston rod                 
                       extending from said piston for connection to relatively move                
                       said yoke with respect to said mounting member wherein the                  
                       pipeline insertion apparatus extends from the pipeline                      
                       parallel to the insertion rod, and wherein the application                  
                       of pressurized fluid to the piston moves the piston rod to                  
                       move said yoke towards or away from the pipeline to insert                  
                       or retract the measuring end of the insertion rod into the                  
                       pipeline wherein the pair of hydraulic cylinders operate                    
                       jointly in response to a common pressurized fluid system to                 
                       provide movement of the rod without bending from said pair                  
                       of cylinders to the side of the stuffing assembly.                          
                 The Examiner relies on the following references:
