摘要： A technique for pumping an output fluid, especially a particle-laden abrasive liquid. This technique utilizes an output pump and a drive pump which are interconnected through a common chamber containing a drive fluid, specifically water. The output pump includes an output piston within its own pumping chamber for pumping the output liquid by causing the output piston to move through a complete forward stroke. The drive pump includes a drive piston within its own chamber and means for causing the output piston to move the drive piston through its own complete forward stroke. This pressurizes the drive fluid within the common chamber in a way which causes the output piston to move in the forward direction of its stroke. The two pumps are configured such that the forward stroke of the drive piston defines a greater swept volume than the forward stroke of the output piston, thereby to ensure that the output piston will always move through its entire forward stroke before the drive piston. At the same time, means are provided for continuously replenishing the drive fluid with discrete amounts of cooler drive fluid in order to ensure that the temperature of the overall drive fluid remains at an acceptable low level.
摘要翻译： 用于泵送输出流体，特别是含有颗粒的研磨液体的技术。 该技术利用输出泵和驱动泵，其通过包含驱动流体（特别是水）的公共室相互连接。 输出泵包括在其自己的泵送室内的输出活塞，用于通过使输出活塞移动通过完全向前冲程来泵送输出液体。 驱动泵包括在其自己的室内的驱动活塞和用于使输出活塞通过其自身的完全向前行程移动驱动活塞的装置。 这样会使得输出活塞在其行程的前进方向上移动的方式对共用室内的驱动流体加压。 两个泵构造成使得驱动活塞的向前冲程比输出活塞的向前冲程形成更大的扫掠体积，从而确保输出活塞总是在驱动活塞之前的整个前进行程中移动。 同时，提供了用于使用离散量的较冷驱动流体连续地补充驱动流体的装置，以便确保整个驱动流体的温度保持在可接受的低水平。

摘要： The technique for replacing an existing underground cable and a specific apparatus for doing so are disclosed herein. The apparatus includes a main body or cable follower which is interconnected with the cable to be replaced for slidable movement along the latter. At the same time, the apparatus provides means for reaming around the cable, preferrably by means of one or more fluid jets. Once the soil surrounding the cable has been loosened using this apparatus, the cable can be easily pulled out of the ground. At the same time, the replacement cable can be attached to the existing cable and pulled into its place.

This apparatus includes a main body or cable follower which is interconnected with the cable to be replaced for slidable movement along the latter. In order to accomplish this, the apparatus includes a specifically designed mechanism for releasably gripping the cable at least at one end preferably two points along the cable in a specifically controlled fashion. At the same time, the apparatus provide means for reaming around the cable, preferably by means of one or more floor jets. Once the soil surrounding the cable has been loosened using this apparatus, the cable can be easily pulled out of the ground. A replacement cable can be attached to the existing cable and therefore pulled into place.

摘要： A dual conduit drill string used in drilling holes for geothermal, oil and gas wells, and the like, comprises a removable inner conduit to permit the use of salvage or repair equipment within the outer conduit. The outer conduit comprises standard API drill pipe sections which are each slightly modified to receive the removable inner conduit sections. Each inner conduit section is provided with flexible hangers for suspending the weight of the inner conduit from a support ledge formed on the interior surface of the drill pipe. The hangers permit upward removal motion and rotation of the inner conduit with respect to the drill pipe, but prevent downward motion. Individual inner conduit sections are joined together at lockable stab joints in which locking is accomplished by the rotatable engagement of a key and locking socket. Preferably, the inner conduit is manufactured in uniform lengths and mounted in drill pipe sections of non-uniform lengths by means of drill pipe adaptor subs. In addition, a removal tool can be used to remove the inner conduit from the drill pipe by engaging the hangers of the lowest inner conduit.

摘要： An underground boring apparatus including a forwardmost boring head is disclosed herein along with a particular technique for guiding the boring head through the earth along both linear and non-linear paths. In a specific embodiment, the apparatus utilizes an elongated shaft arrangement supporting the boring head at its front end and a tubular housing supporting an intermediate segment of said shaft arrangement for pivotal movement about one of a number of different axes whereby to cause the boring head to pivot relative to the housing. An arrangement of piston/cylinder units is disposed within the housing for pivoting the shaft arrangement in a controlled fashion whereby to determine the direction of movement of the boring head through the earth. This arrangement of piston/cylinder units not only serves to maintain the shaft arrangement and boring head in a pivoted position for causing the latter to move in a curved path, but also serves to maintain the shaft arrangement and boring head in coaxial relationship with the tubular housing for causing the boring head to follow a straight line path.
