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.
摘要翻译：一种运送装置，用于通过由水平或高度偏离的钻孔穿过的地层输送至少一个测井工具。输送装置包括一对可枢转地安装到支撑构件上的弓形凸轮，用于将每个凸轮的弓形表面偏置成与钻孔壁接触的弹簧构件，以及可操作地连接到每个凸轮的致动器。测井工具附着在输送装置上。当任一致动器在第一方向上被激活时，连接到激活的致动器的凸轮向前线性地移动，并且凸轮的弓形表面沿钻孔壁滑动。当任一致动器在第二方向被致动时，被致动的致动器向后拉动所连接的凸轮，并且弹簧构件因此促使凸轮的弧形表面锁定在井眼壁上。一旦凸轮被锁定，致动器的进一步移动就沿着高度偏斜或水平的钻孔向前推进输送装置和测井工具。

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.
摘要翻译：电缆释放装置包括安装在壳体的一端的壳体和闩锁。闩锁具有中心开口和延伸到壳体中的多个突出构件。可释放的连接器安装在壳体内。致动器的一端设置在闩锁中的中心开口中，另一端与可释放连接器接触。致动器可在可释放连接器启动之前的第一位置和可释放连接器被激活的第二位置之间移动。在可释放连接器的激活之前，通过突出构件和壳体之间的过盈配合将闩锁保持就位。当可释放连接器被启动时，突出构件通过向闩锁施加张力而偏转，从而将闩锁从壳体释放。
