摘要： New locking connector assemblies and telescoping extension/retraction assemblies are disclosed that operate on the natural spring rate constraints of radial protrusions or radially constrained rings as they interact with engaging members to provide the locking force and permit the connector and extension retraction assemblies to be engage and disengaged or extended and retracted.
摘要翻译：公开了新的锁定连接器组件和伸缩式延伸/缩回组件，其在径向突起或径向受限环的自然弹簧速率约束下工作，因为它们与接合构件相互作用以提供锁定力并允许连接器和延伸件缩回组件接合并且脱离或伸展和缩回。

摘要： An apparatus for telemetering a downhole parameter from a well. The apparatus comprises a housing having a bore. The apparatus further comprises an annular main valve with an enlarged end positioned within the bore, with the main valve having a center of axis. A restrictor is concentrically disposed within the bore, the restrictor configured to define an annular passage with the main valve. The apparatus also includes: a pressure device for supplying hydraulic pressure to the main valve; a control valve, operatively associated with the restrictor member, for controlling pressure to the main valve; and a solenoid control valve assembly for activating the control valve. In one preferred embodiment, the solenoid control valve assembly comprises a controller for emitting an electrical signal, a coil that receives the electrical signal and generates a magnetic field, a solenoid static pole receptive to the generated magnetic field, and a solenoid moving pole responsive to the magnetic field so that the solenoid moving pole moves in a direction towards the solenoid static pole. A method for communicating a downhole parameter is also disclosed.
