摘要： A robotic apparatus for positioning a tool or work hand that incorporates a compliant wrist effective to adjust to delicate but misaligned portions of the workpiece, comprising (a) structure for magnetically supporting a positioning member carrying a gripper tool; (b) pneumatic structure for selectively separating and floating the positioning member from said supporting structure to permit lateral adjustment of the positioning member in response to small forces received from the gripper tool as it carries out gripping; and (c) structure for locking the positioning member to the supporting structure upon completion of the desired lateral adjustment. A method of using such compliant wrist concept, comprising (a) magnetically suspending a positioning plate from a magnet, the plate carrying the gripper tool; (b) injecting a film of air between the interface of the magnet and plate to provide floating separation therebetween enabling ease of lateral movement; (c) closing a gripper tool about the part to be gripped causing any offcenter gripping forces to be translated back to the plate resulting in lateral movement in response thereto for seeking a centering position; and (d) upon achieving the desired centering position, deactivating the air injection to permit the magnet to lock the plate in position relative to the magnet for further robotic movement.

摘要： A dual phase riser flotation system contains a number of passive phase buoyancy modules of syntactic foam contained within an outer skin, and a number of active phase buoyancy modules which are similar to air canisters in that they may be inflated or deflated as required to provide levels of buoyancy. The passive phase buoyancy modules may contain tubes filled with air, a compressed gas such as nitrogen, or evacuated to provide additional buoyancy. Charge and discharge valves connect gas flow lines to a manifold system serving the active phase buoyancy modules.

摘要： A new wellhead housing structure which utilizes identical units of a unique wellhead housing of selected internal diameter and pressure rating. Each wellhead housing utilizes a new flexible bowl ("flexbowl") hanger support ring which may be installed and removed as desired during assembly of the wellhead structure during completion of the well. Each wellhead housing forms an internal circumferential groove to receive the flexible bowl hanger support ring in position to receive and support different kinds and sizes of hangers for casing, protective sleeves, and the like. The flexible bowl support ring is drawn into a contracted position. The contracted support ring will pass through the wellhead housing and is seated by a setting tool. Subsequently, a tubing or casing hanger may be landed upon the support ring and supported by the support ring which serves the same functions as the bowl seat in a conventional wellhead housing. The support ring may be removed by a removal tool.
摘要翻译： 一种新的井口外壳结构，其采用相同的单元，其具有选定的内径和压力等级的独特的井口壳体。 每个井口壳体都使用一个新的柔性碗（“弯头”）衣架支撑环，可在井的完井期间组装井口结构期间根据需要安装和拆卸。 每个井口壳体形成内部周向凹槽，以将柔性碗挂架支撑环接纳在适当位置，以容纳和支撑用于套管，保护套等的不同种类和尺寸的衣架。 柔性碗支撑环被拉入收缩位置。 承包的支撑环将穿过井口外壳，并由安装工具安置。 随后，管道或套管悬挂器可以落在支撑环上并由支撑环支撑，支撑环在常规的井口壳体中起到与碗座相同的作用。 支撑环可以通过去除工具去除。

摘要： A fire resistant connection (14) that embodies a sealing means (44) and that is operable for purposes of effectuating the establishment of a fire resistant seal between mating surfaces (52, 54), and in particular mating surfaces (52, 54) of the type that commonly are found to be present in wellhead and valve equipment (10). The subject fire resistant connection (14) includes mating seal surfaces (52, 54) and the aforementioned sealing means (44). The sealing means (44) comprises a seal ring (44), which includes a plurality of seal lips (46, 48) and a dovetail-shaped rib (50), the latter (50) being formed on the seal ring (44) so as to be located in interposed relation between the pair of adjacent seal lips (46, 48). Each of the plurality of seal lips (46, 48) is suitably configured so as to be positionable in sealing engagement with a corresponding one of the mating seal surfaces (52, 54), the latter (52, 54) embodying a configuration that is complementary in nature to that of the seal lip (46, 48) engaged thereby. Likewise, the rib (50) is suitably configured such that when the seal lips (46, 48) are in sealing engagement with the mating seal surfaces (52, 54), the rib (50) is also engaged by the mating seal surfaces (52, 54) and is locked in position thereby.

摘要： A fuel product derived from waste products and processes for using and forming the products are provided. Broadly, the fuel product comprises a self-sustaining body formed from a homogenous mixture including solid components derived from livestock waste (e.g., swine manure) and a second waste product different from the livestock waste (e.g., sawdust or paper). The mixture has a moisture content of from about 10-40% by weight and the formed body has a bulk density of from about 20-40 lbs/ft.sup.3. The mixture or formed body is heated to a temperature of at least about 800.degree. F. in order to produce at least about 5000 BTUs of energy per pound of mixture or body heated.
