摘要： A downhole well tool is provided which includes a shifting sleeve for opening a flow communication port. The well tool includes first and second primary seal elements positioned upstream and downstream, respectively, of the port as well as upstream and downstream of the threaded connections between the well tool and sections of tubing forming the well flow conduit. A fluid diffuser element may be included to abate flow damage across the primary seal elements during the shifting of the sleeve. A method of selectively transmitting fluid incorporating said well tool also is disclosed.

摘要： A sealing apparatus is provided for sealing between concentric relatively moveable tubular members. The sealing apparatus is comprised of a plurality of retainer seal rings, made of a high temperature thermoplastic, and between each retainer seal ring is a thermoplastic seal ring constructed of a normal temperature service thermoplastic. The thermoplastic seal rings are alternately spaced with the high temperature thermoplastic retainer seal rings. The retainer seal rings and the thermoplastic seal rings are cylindrical rings having a radial cross-section of a general chevron shape. Energization to press both sets of seals into sealing engagement with the two relatively moveable tubular members is accomplished by the interaction of an axial interference fit between alternating seal rings, a diametrical interference fit between the relatively moveable wellbore surfaces and the seal rings, and wellbore fluid pressure. Wellbore fluid pressure pushes against the female portion of the general chevron shape to flare outward the retainer seal rings into sealing engagement with the relatively moveable tubular members. At higher wellbore temperatures, the retainer seal rings, which are alternated every other one with the thermoplastic seal rings, maintain the shape of the thermoplastic seal rings so that they will sealingly engage the relatively moveable members when the seal assembly is cooled from higher wellbore temperatures to lower wellbore temperatures.

摘要： A lamp reflector assembly includes a fixture having a base and a support member movably attached to the base. Attached to the support member is a pair of spaced-apart arms, each having an electrical receptacle. Connected to the electrical receptacles are electrical contacts of opposing ends of an elongate lamp, with a middle portion that emits radiation. Attached to the base of the fixture is a concave reflector having a pair of clearance holes sized to permit the end portions of the lamp to pass through, to locate the electrical contacts outside the reflector. The resulting combination provides adjustability of the position of the lamp relative the position of the reflector, to focus the radiation reflected generally forwardly from the reflector. The present invention offers important advantages over a prior art adjustable assembly, where the reflector is bonded to a sheet metal bracket.

摘要： A pistol caliber conversion assembly having a slide assembly housing components of lightweight characteristics so as to accept and permit an interchange of a variety of caliber ammunition. The assembly includes a rail and groove arrangement for slidably mounting a slide housing onto the frame and a recoil mechanism for urging a barrel into a reset position after firing. An open lock mechanism selectively engages the slide housing with the frame and sets to an automatic open position upon ejecting of a last round from the ammunition chamber. The critical selection of high strength-to-weight ratio materials permits machining away of excess materials to reduce weight while maintaining sufficient hardness and mass to handle firing loads.
