摘要： A prepacked well screen assembly for preventing sand from being produced with well fluids. The assembly includes a filter medium surrounded by an outer support, with the outer surface of the filter medium being fluted or otherwise shaped to have a larger outer surface area than the surface area of the outer support member surrounding the filter medium.

摘要： The present invention provides a well filter assembly for incorporation in a production system which will initially allow passage of particles which will only minimally damage the interior of the production system. After a period of time, the filter assembly will preclude passage of all damaging particles while allowing passage of those particles which will not deteriorate or obstruct the production system. Additionally, the well screen assembly is designed to mechanically break down the filter cake which was formed during drilling of the well in order to preclude plugging of the filter. Further, the filter of the prepacked well screen assembly is of sufficient strength so as to maintain its filtering capacity even after damage due to deformation. Finally, a method is provided for utilizing the well filter assembly in a production system.
摘要翻译：本发明提供一种用于结合到生产系统中的井过滤器组件，其将最初允许仅最小程度地损坏生产系统内部的颗粒通过。一段时间后，过滤器组件将排除所有有害颗粒的通过，同时允许那些不会劣化或阻碍生产系统的颗粒通过。此外，井筛组件被设计成机械地分解在钻井期间形成的滤饼，以防止过滤器堵塞。此外，预包装的井筛组件的过滤器具有足够的强度，以便即使在由于变形而损坏之后也能保持其过滤能力。最后，提供了一种在生产系统中利用井过滤器组件的方法。

摘要： A double spindle grinding machine has a pair of grinding spindles mounted on feed tables for performing two independent grinding operations. A pair of work spindles for holding workpieces to be ground are rotatably mounted on a supporting frame which undergoes angular displacement in forward and reverse directions through an arc of 180.degree. to alternately position the workpieces held by the two spindles opposite alternate ones of the two grinding spindles. A swing shaft is connected to the supporting frame and is alternately driven in forward and reverse directions to displace the supporting frame to extreme forward and reverse positions so as to alternately position the workpieces in opposed relation to alternate ones of the grinding spindles. A clamping device coacts with the supporting frame to releasably clamp the frame in either extreme position, and the clamping device includes a pair of vertically slidable clamp rods connected through a linkage to a reciprocal fluid motor which effects upward and downward movement of the clamp rods between unclamping and clamping positions. A clamp block is secured to each clamp rod and coacts with a clamp member secured to the supporting frame to releasably clamp the frame in the extreme forward and reverse positions in response to actuation of the fluid motor to drive the clamp rods to the clamping positions.

摘要： Method and apparatus for processing substrates through a number of wet treatments. A substrate is set on a substrate rotating means for rotation in a horizontal face-up position, within a housing which is open on its top side. By a treating liquid feed means having a treating liquid feed nozzle member, at least one kind of treating liquid is supplied onto upper surfaces of the substrate being rotated by the substrate rotating means. The treating liquid feed nozzle member is supported on a movable arm for displacement to and from an operative position vertically confronting the substrate and a receded standby position away from the substrate on the substrate rotating means. Located face to face with lower surfaces of the substrate is a nozzle means which supplies a fluid to the lower side of the substrate.

摘要： A center column type rotary index machine comprises a rotary index table which is intermittently rotated in angular increments to position a jig mounted on the index table at predetermined processing stations. A vertically movable center column undergoes upward and downward movement relative to a fixed frame portion of the machine. In order to ensure precise positioning of the jig at the processing stations, a clamp rod is slidably mounted on the fixed frame portion and is provided at its lower end with a taper portion which coacts with a complementary-shaped taper portion on the index table to position the index table so that the jig is precisely positioned at one of the processing stations. A link lever is pivotally mounted on the frame portion of the machine and has one lever arm pivotally connected to the upper end of the clamp rod and another lever arm pivotally connected to a slidable member which is slidably mounted in a sleeve affixed to the center column so that upward movement of the center column from its lowermost position effects pivotal movement of the link lever to cause downward movement of the clamp rod thereby bringing the clamp rod taper portion into engagement with the index table taper portion. The slidable member is biased in the upper direction by a spring housed within the sleeve so that after initial upward movement of the center column to bring the two taper portions into engagement, further upward movement of the center column effects compression of the spring thereby exerting a downward clamping force on the clamp rod to maintain the two taper portions in snug engagement during the processing of the workpiece held on the jig while the same is in the predetermined processing state.
摘要翻译：中心柱型旋转指数机包括以角度增量间歇地旋转的旋转分度台，以将安装在指定台上的夹具定位在预定处理站。垂直移动的中心柱相对于机器的固定框架部分经历上下移动。为了确保夹具在加工站的精确定位，夹紧杆可滑动地安装在固定框架部分上，并在其下端设有锥形部分，该锥形部分与分度台上的互补形状的锥形部分共同作用，定位索引表，使得夹具精确地定位在处理站之一处。连杆被枢转地安装在机器的框架部分上，并且具有可枢转地连接到夹紧杆的上端的一个杠杆臂和可枢转地连接到可滑动地安装在固定到中心柱的套筒中的可滑动构件的另一杠杆臂使得中心柱从其最下位置的向上运动实现连杆的枢转运动，从而引起夹紧杆的向下运动，从而使夹杆锥形部分与分度台锥形部分接合。可滑动构件通过容纳在套筒内的弹簧沿上方偏压，使得在中心柱的初始向上运动以使两个锥形部分接合之后，中心柱的进一步向上运动会影响弹簧的压缩，从而施加夹持杆上的向下夹持力，以在保持在夹具上的工件的处理期间保持两个锥形部分处于接合状态，同时处于预定的处理状态。
