摘要： The present invention includes a method of producing a reinforced extrusion product, the product of the method, and the apparatus for making a reinforced extrusion product. The method of producing an extruded composite of the present invention, comprises the general steps of: (a) extruding a longitudinally oriented composite precursor comprising: (1) at least one thermoplastic polymeric material and (2) a core mixture of at least one thermosetting resin and at least one filler material; whereby the thermoplastic polymeric material(s) is/are extruded so as to substantially enclose a space, and whereby the core mixture is disposed in the space; and (b) maintaining the composite precursor under conditions whereby the thermoplastic polymeric material(s) become(s) cooled and the thermosetting resin(s) become(s) cured so as to form the extruded composite of the present invention. The present invention also includes an extruded composite made in accordance with the method of the present invention. The present invention also includes a coextrusion apparatus comprising: (1) an extrusion die adapted to form a hollow profile extrudate; (2) at least one extruder head adapted to extrude a thermoplastic material through the extrusion die so as to form a hollow thermoplastic extrudate; and an insulated injector tube adapted to coextrude a thermosetting material with the thermoplastic material and into the hollow thermoplastic extrudate.

摘要： A method and apparatus for acquisition of downhole well data such as bottomhole pressure, bottomhole temperature, etc. which is utilized in conjunction with other well equipment such as gravel packer tools especially for data acquisition at well depths that are ordinarily rendered inaccessible by tools and other equipment located within the well. An instrument housing is fixed to other well equipment and is provided with equalizing ports which are normally closed by a sealing collet element. As the instrument is run into the well and into the instrument housing its upper end establishes sealing with the instrument housing to isolate the data acquisition chamber thereof from the flow passage from the well servicing tool. As it is run into the housing, a collet actuator mechanism unseats the collet to equalize pressure internally of the instrument housing with the external fluid pressure environment. After the acquisition of well data has been concluded, as the instrument is withdrawn from the instrument housing the collet actuator stem will shift the collet from its unseated position back to its seated and sealed relation thereby preventing further communication of the external fluid environment with the internal chamber of the instrument housing.

摘要： The present invention has several aspects: an extrusion apparatus, a method of making a curved extrusion, and a curved extrusion made by the method. In broadest terms, the apparatus of the present invention comprises: (1) an extruding means, typically an extruder, adapted to produce an extrudate having a cross-section; (2) a plurality of guide members arranged so as to form a curvilinear path through which the extrusion is passed, each of the guide members having an aperture having substantially the same shape as the cross-section of the extrusion, whereby the plurality of guide members are adapted to form the extrusion into a curved shape while maintaining the cross-section of the extrusion; and (3) mechanical means adapted to conduct the extrusion through said plurality of guide members, such as an extrusion puller.
