摘要： An improved downhole tool apparatus including, but not limited to, packers and bridge plugs which more fully utilize highly stressed non-metallic components, including slips, slip wedges, and packer element retaining shoes than prior tools. The non-metallic packer element retaining shoes of the present invention are preferably made of separate shoe segments initially held in place by at least one retaining band. Such non-metallic packer element shoes do away with troublesome prior art metallic shoes and backups which tended to spin upon each other or about the mandrel while milling or drilling the tool out of a wellbore. Therefore, the subject invention increases the ability to drill or mill downhole tools out of a well bore in less time than it would take with using conventional or non-conventional drilling or milling techniques or equipment.

摘要： An apparatus and method of anchoring a work string to a packer set in a wellbore and releasing therefrom. The apparatus includes a stinger, a collet slidably disposed on the stinger and having a plurality of collet fingers adapted for engaging the packer, a shear ring member shearably attached to the stringer and adapted for holding the collet fingers into engagement with the packer. The packer may be normally released by applying torque to the work string such that the collet fingers are unthreaded from the packer. Torque is applied from the stinger to the collet fingers by a load ring attached to the stinger and having splines extending between the collet fingers so that torque may be applied to the collet without applying torque to the shear ring member. In the event that rotation is not possible, tension applied to the work string and the stinger will cause the shear ring member to be shearably released from the stinger so that the collet fingers may be pulled longitudinally and thereby disengaged from the packer. A method of use of the apparatus is also disclosed.
摘要翻译： 将工作串固定在井筒中的封隔器上并将其释放的装置和方法。 该装置包括一个托管架，一个可滑动地设置在托管架上并具有适于接合封隔器的多个夹头的夹头，一个剪切环构件，可剪切地连接到纵梁上，并适于夹紧夹头与封隔器接合。 打包机通常可以通过向工作串施加扭矩来松开，使得夹头从封隔器上脱开。 通过安装在托管架上的负载环将锭子施加到夹头上，并且具有在夹头之间延伸的花键，使得可以在不向剪切环构件施加扭矩的情况下将扭矩施加到夹头。 在无法旋转的情况下，施加到工作线和托管架上的张力将导致剪切环构件从托管架上被可剪切地释放，使得夹头可以被纵向拉伸，从而与封隔器脱离接合。 还公开了该装置的使用方法。

摘要： A new type of overspeed control system for a rotor driven by wind or some other fluid flow. The rotor support is mounted so that it can move back some small distance along the direction of the fluid flow, the rotor axis remaining in substantially the same direction during this movement. This backward movement is in response to the thrust generated by the lift and drag forces on the rotor impellers. At a predetermined thrust force, indicating that the rotor is operating in a fluid velocity high enough to cause overspeeding, the backward movement of the rotor engages a brake to slow the rotor. Essential to the invention is the use of the backward movement of the rotor to brake the rotor.

摘要： A low pressure, high temperature composite bridge plug. The bridge plug comprises a mandrel with a plurality of slips disposed therearound. A wedge is initially attached to said mandrel and in planar contact with the slips for forcing the slips radially outwardly into gripping engagement with a wellbore. An elastomeric sealing element is disposed on the mandrel and compressed between the wedge and a shoulder on the mandrel to expand the packing element radially outward into sealing engagement with the wellbore. A plurality of ratchets retained in a ratchet body grippingly engage the mandrel to prevent the plug from unsetting. The mandrel, slips, wedge and ratchet body are preferably made of non-metallic, composite materials for easy drilling.

摘要： Apparatus for heat transfer labelling of articles using a resilient pad maintained at elevated temperatures. Decorative laminates affixed to a support member such as a web are fed to a heated platen. A resilient pad consisting of a silicone elastomer is pressed against the laminate at the heated platen, whereby the laminate adheres to the pad when it retracts from the platen. The heated pad is then pressed against an article to be labelled, to which the transfer substrate adheres in preference to the pad surface. The resilient pad is typically heated to a temperature above ambient temperature but lower than that of the heated platen. The pad is heated by repetitive contact with the platen, and additionally by an independent heater. The pad may include one or more interior heating elements, or an exterior radiant heater located adjacent the pad during periods between label transfers. This apparatus is well suited to the labelling of articles of a wide variety of sizes, shapes, and materials.

摘要： A decorative laminate and method of transferring designs onto articles. The laminate is formed of a transfer substrate affixed to a support member. The transfer substrate is composed of a protective layer, an ink layer and a resinous coating layer. Optionally, a barrier layer is provided beteen the resinous layer and the ink layer. In many applications the protective coating layer may be omitted. The laminate is applied to an article using a heated silicone rubber transfer pad to which the transfer substrate adheres during the transfer process.
