摘要： A pump rod drive and torque release mechanism for use in association with a downhole pump positioned within a well. The pump rod drive and torque release mechanism comprises a central housing having a generally hollow interior, a drive shaft received within the central housing, a drive rod received within the central housing, and a torque transfer mechanism positioned within the central housing. The drive shaft may be operatively connected to a pump rod rotator to impart rotational movement to the drive shaft. The drive rod may be operatively connected to a downhole pump so as to enable transference of rotational energy from the drive rod to the downhole pump. The torque transfer mechanism has an engaged position wherein it operatively connects the drive shaft to the drive rod such that rotation of the drive shaft causes rotation of the drive rod. The torque transfer mechanism also has a disengaged position wherein it operatively disconnects the drive shaft from the drive rod. When it is in its disengaged position, the torque transfer mechanism permits rotation of the drive rod relative to the drive shaft and a release of torque exerted on the drive rod by fluid present in the well above and bearing against the downhole pump.

摘要： This invention relates to the manufacture of Cadmium Mercury Telluride (CMT) on patterned silicon, especially to growth of CMT on silicon substrates bearing integrated circuitry. The method of the invention involves growing CMT in selected growth windows on the silicon substrate by first growing one or more buffer layers by MBE and then growing the CMT by MOVPE. The growth windows may be defined by masking the area outside of the growth windows. Growth within the growth windows is crystalline whereas any growth outside the growth windows is polycrystalline and can be removed by etching. The invention offers a method of growing CMT structures directly on integrated circuits removing the need for hybridisation.

摘要： A tubing string rotator for rotating a tubing string in a well having a downhole pump. The tubing string rotator includes a housing having a first portion and a second portion. At least the second portion of the housing is adapted to be operatively connected to the end of a length of the tubing string such that rotational torque applied to the tubing string through the operation of the pump is transferred to the second portion of the housing. The rotator further includes means to permit the controlled rotation of the second portion, together with the tubing string connected thereto, relative to the first portion of the housing when the ability of the first portion to rotate is retarded or eliminated, and when rotational torque is supplied to the tubing string through the operation of the pump.

摘要： A CAM and method for operating a CAM are presented. Copies of a CAM database are duplicated and placed in a first set of CAM locations and a second set of CAM locations. An error detector is used to determine false matches in the case of soft errors within the entries producing those false matches. While the entries producing a match should have the same index location, errors might cause those match lines to have an offset. If so, the present CAM, through use of duplicative sets of CAM locations, will detect the offset and thereafter the values in each index location that produces a match, along with the corresponding parity or error detection encoding bit(s). If the parity or error detection encoding bit(s) indicate an error in a particular entry, then that error is located and the corresponding entry at the same index within the other, duplicative set of CAM locations is copied into the that erroneous entry. Since duplicative copies are by design placed into the first and second sets of CAM locations, whatever value exists in the opposing entry can be written into the erroneous entry to correct errors in that search location. The first and second sets of CAM locations are configurable to be duplicative or distinct in content, allowing error detection and correction to be performed at multiple user-specified granularities. The error detection and correction during search is backward compatible to interim parity scrubbing and ECC scan, as well as use of FNH bits set by a user or provider.

摘要翻译： 提出了CAM和CAM的操作方法。 CAM数据库的副本被复制并放置在第一组CAM位置和第二组CAM位置中。 误差检测器用于在产生这些假匹配的条目中的软错误的情况下确定错误匹配。 虽然产生匹配的条目应该具有相同的索引位置，但是错误可能导致这些匹配行具有偏移量。 如果是这样，通过使用CAM位置的重复集合，当前的CAM将检测偏移，然后检测产生匹配的每个索引位置中的值以及相应的奇偶校验或错误检测编码位。 如果奇偶校验或错误检测编码位指示特定条目中的错误，则该错误被定位，并且另一个重复的CAM位置集合中相同索引处的相应条目被复制到该错误条目中。 由于通过设计将重复副本放置在第一和第二组CAM位置中，所以相反条目中存在的任何值都可以被写入错误的条目中以纠正该搜索位置中的错误。 第一和第二组CAM位置可配置为内容重复或不同，允许以多个用户指定的粒度执行错误检测和校正。 搜索期间的错误检测和校正向后兼容到临时奇偶校验和ECC扫描，以及使用由用户或提供者设置的FNH位。

摘要： A pump rod clamp for gripping a pump rod in an oil, gas or water well. The pump rod clamp comprises a central housing having a longitudinal bore for receiving a pump rod, a plurality of clamping members receivable within the central housing, and one or more actuators to cause the clamping members to be moved between an activated position where they grippingly engage the pump rod and a deactivated position where they are released from contact with the pump rod. Each of the clamping members have a leading face that includes one or more gripping inserts releasably secured thereto. The gripping inserts having outer faces generally aligned with the pump rod for grippingly engaging the pump rod when the clamping members are in their activated position such that force exerted by each individual clamping member against the pump rod is concentrated and distributed over the outer faces of the one or more gripping inserts of each clamping member.

摘要： A ball grid array (BGA) package is disclosed. An interconnect structure is formed on a substrate that electrically connects the electrical device to be housed in the BGA package to the solder balls thereon. Contact pads are formed over the top surface of the substrate. These contact pads electrically connect to the interconnect structure. A layer of solder mask is formed over the substrate that includes openings that overlie the contact pads. The BGA is then completed using conventional process steps. Thereby, a BGA package is formed that includes contact pads disposed such that the contact pads are accessible from the top of the BGA package, making these contact pads easily accessible. Thus, when the BGA is attached to a circuit board, connection to circuits of the electrical device is obtainable.
