    摘要： A pull-ring for an electrical device, such as a high-voltage fuse, which may be placed in a mounting. The pull-ring operates a latch, which is capable of holding the fuse closed in the mounting, only when it is reciprocated. The pull-ring is pivotable independently of its reciprocation without affecting the condition of the latch. Accordingly, when a trunnion on the device is in a hinge of the mounting and a pushing force is applied to the pull-ring with a tool to close the device, the natural decrease in the interior angle between the tool and the device can rotate the pull-ring without preventing the latch from holding the device closed. Further, whether the pushing force or a pulling (opening) force is applied to the pull-ring, the direction of application of the force may be adjusted or may naturally change before, during,or after such force application with affecting the ability of the latch to hold the device closed. The tool may, therefore, be either a non-grasping tool (a "hot stick") or one (a "shotgun stick") capable of grasping the pull-ring. In the latter event, when the tool grasps the pull-ring and the trunnion is out of the hinge, the pull-ring is biased to a pivotal orientation whereat the trunnion is presented for convenient insertion into the hinge upon manipulation of the tool.

    摘要： A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.
