to the upper annulus 56 by virtue of seal 52 going back to the fig3 position this is accomplished with a j slot mechanism that will be described below in the circulation mode of fig4 the return flow through the screens not shown is shown by arrows 60 the positions in fig3 and 4 can be sequentially obtained with a pickup and set down force using the j slot assembly mentioned before in fig5 the string 12 has been raised until the metering dogs 38 have landed against a shoulder 62 a pull of a predetermined force for a predetermined time will displace fluid through an orifice and ultimately allow the dogs 38 to collapse into or past bore 64 as shown in fig6 also picking up to the fig5 position lets the reciprocating set down device 42 come out of bore 40 so that it can land on shoulder 66 for selective support picking up the reciprocating set down device 42 off shoulder 66 and then setting it down again will allow the reciprocating set down device 42 to re enter bore 40 once the valve assembly 44 is pulled past bore 40 as shown in fig6 and returned back into bore 40 it is armed re entering bore 40 then close the valve assembly 44.
