    • A chinrest pad system designed to hold a standard chinrest used with a stri ng instrument that minimizes dampening of vibration and prevents damage caused by the metal components touching the edges of the instrument. The system includes pads located under the support surface of the chinrest member and on top of the lower lip plate used on the lower clamping member. The pads are specifically designed to partially engage the instrument's upper and lower edges and match the curvature of instrument surface immediately adjacent to the edge. Each pad also includes a rear extending lip that bends slightly around the upper or lower edge and extends rearward to prevent the metal rods used with the turnbuckles from contacting the rear surface. During assembly, the pads are positioned over t he upper and lower edges so that the compression forces exerted by the support surface an d the lower lip plate are centrally located over the sidewall transverse axis, thereby minimizing dampening of vibration.

    • A lock assembly for a mechanically set packer for deep deployments is described. The lock housing wall has at least one bore for a rod piston that is selectively actuated when wellbore hydrostatic is allowed to reach on side of the piston. Movement of the piston, after breaking a shear pin, allows a c-ring to spring outwardly and out of a locking groove in the mandrel so that the mandrel can be string manipulated with respect to the housing to set the packer. Once unlocked the lock assembly remains defeated. The piston can be optionally exposed to hydrostatic and will unlock at a given depth without manipulation of the wellbore annulus pressure. Other mechanisms to admit wellbore hydrostatic to move the piston or to move the piston in general by other techniques are described.
    • 描述了用于深部署的用于机械设置的封隔器的锁组件。 锁壳体壁具有用于杆活塞的至少一个孔,当井筒静液压允许到达活塞侧时,该活塞被选择性地致动。 活塞在断裂剪切销之后的运动允许c形环向外弹出并离开心轴中的锁定槽,使得心轴可以相对于壳体进行弦线操纵以设置封隔器。 一旦解锁,锁组件仍然失败。 活塞可以任选地暴露于静水压下,并且将在给定的深度解锁,而不用操纵井筒环空压力。 描述通过其它技术来承认井筒静压以移动活塞或一般移动活塞的其他机构。
