摘要： A cable release apparatus includes a housing and latch mounted at one end of the housing. The latch has a central opening and a plurality of projecting members extending into the housing. A releasable connector is mounted inside the housing. An actuator has one end disposed in the central opening in the latch and another end in contact with the releasable connector. The actuator is movable between a first position prior to activation of the releaseable connector and a second position wherein the releasable connector is activated. Prior to activation of the releasable connector, the latch is held in place by an interference fit between the projecting members and the housing. When the releasable connector is activated, the projecting members are deflected by applying tension to the latch, thereby releasing the latch from the housing.

摘要： A substantially constant force actuator that is applicable to centralizers, anchors and tractors for use in wells and is applicable to lifting devices such as jacks and load supporting devices. One or more sets of linkage arms are angularly movable by the force of one or more force transmitting members from a minimum angle with the force transmitting members at maximum spacing to a maximum angle with the force transmitting members at minimum spacing to impart a substantially constant force to an object or surface, with the direction of the force being substantially perpendicular to the direction of relative linear movement of the force transmitting members. With the linkage arms at their minimum angles, movement control elements on at least one of the force transmitting members react with guide surfaces of the linkage arms to achieve angular linkage movement and to develop a substantially constant force during angular linkage movement.

摘要： A conveyance apparatus for conveying at least one logging tool through an earth formation traversed by a horizontal or highly deviated borehole. The conveyance apparatus comprises a pair of arcuate-shaped cams pivotally mounted to a support member, a spring member for biasing the arcuate surface of each cam into contact with the borehole wall, and actuators operatively connected to each cam. A logging tool is attached to the conveyance apparatus. When either actuator is activated in a first direction, the cam connected to the activated actuator is linearly displaced forward and the arcuate surface of the cam slides along the borehole wall. When either actuator is activated in a second direction, the activated actuator pulls the connected cam backwards and the spring member thereby urges the arcuate surface of the cam to lock against the borehole wall. Once the cam is locked, further movement of the actuator propels both the conveyance apparatus and the logging tool forward along the highly deviated or horizontal borehole.
