the push rod 110 movement by reconfiguration of the stack of washers 88 and or the parts that are unleashed to move with the pressure removal on the 12 th cycle optionally the boost force from the washers 88 can last for the duration of the movement of the push rods 110 note that if there is no tool operating mechanism available to stop the push rods 110 such as when the tool t is bench tested then one travel stop for the push rods 110 can be when the piston coupler 108 hits surface 130 in fig1 alternatively some part of the indexing sleeve 60 can be configured to engage the continuous portion of the shoulder 66 at a rotated location from the discontinuous portion of that shoulder 66 using a surface such as 132 on the indexing sleeve 60 it should be noted that the indexing assembly for this embodiment comprises the moving parts between the indexing spring 28 and the piston coupler 108 and outside the passage 26 whose movement causes the actuating piston 110 to actuate the barrier tool for the subsequent embodiment the indexing assembly comprises the moving parts outside the passage 200 and between and including the indexing spring 210 and the actuating piston coupler 226 whose movement causes actuating pistons 222 to actuate the barrier tool referring to fig1 16 it may be desirable to move the pressure entry point to reach the.
