Abstract: A hanger assembly for supporting a tubular member within an outer well member includes a slip bowl that is moveable between an expanded condition with an enlarged diameter and a contracted condition with a reduced diameter, and has a downward facing slip bowl shoulder on an outer diameter of the slip bowl. Slips with teeth on an inner diameter surface are carried by the slip bowl. The slips are moveable between a retracted position, and an extended position where the teeth protrude radially inward from the inner diameter of the slip bowl. A false bowl has a lower upward facing false bowl shoulder located on an inner diameter and is sized to selectively engage the downward facing slip bowl shoulder. The false bowl also has a downward facing landing shoulder located on an outer diameter that is sized to selectively engage a support shoulder of the outer well member.

Abstract: Systems and methods for positioning tubular members within a subterranean well include inner and outer tubular members extending into the well. An adjustment ring assembly is located between the inner tubular member and the outer tubular member and has an outer ring and an inner ring. The outer ring circumscribes, and is rotatable relative to, the inner ring to adjust the radial offset between a central axis of the wellhead assembly and a central axis of the inner tubular member.

Abstract: A tool for polishing a seal surface of a wellhead assembly includes a cylindrical tool body with an axis. The tool body includes a base member with a first end, and a second end. A tubular skirt member extends from the second end of the base member. The skirt member has a sidewall, a base end connected to the base member, and an open end opposite the base end. A plurality of axial slots extend through the sidewall of the skirt member, the axial slots being spaced circumferentially around the skirt member. A polishing belt is woven through the axial slots of the skirt member.

Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. An isolation sleeve is included with the fracturing system that couples to the fracturing spool and extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A seal is between the isolation sleeve and bore of the wellhead assembly, which is threaded to the isolation sleeve. Manipulating the threaded connection between the isolation sleeve and seal selectively positions the isolation sleeve to designated axial positions within the wellhead assembly.

Abstract: A wellhead assembly includes an outer wellhead member, the outer wellhead member having a locking profile on an inner surface. An inner tubular wellhead member lands within the outer wellhead member, defining a seal pocket between the inner tubular wellhead member and the outer wellhead member. A seal ring is located in the seal pocket. A seal energizing ring urges the seal ring into sealing engagement with the outer wellhead member and the inner tubular wellhead member. An annular lock ring is carried with the seal energizing ring and engages the locking profile. A lock energizing ring retains the annular lock ring in engagement with the locking profile.

Abstract: A tool for retaining an activator ring of a hanger within a wellhead assembly during a fluid pumping process includes an annular fluid pumping sub body having an end selectively coupled with a supply of fluids and a distal end selectively coupled with the hanger. An outer ring assembly circumscribes and rotates relative to the fluid pumping sub body. A retainer ring circumscribes the fluid pumping sub body and selectively abuts the activator ring. A plurality of biasing assemblies that are selectively compressible are located between the outer ring assembly and the retainer ring, so that when the fluid pumping sub body is coupled with the hanger, an axial lockdown force is maintained on the activator ring by the biasing assemblies during the fluid pumping process.

Abstract: The invention discloses an handheld sexual appliance providing improved means for stimulating the Grafenberg area or G-spot of the female genitalia, the appliance comprising an elongate body having a first span, wherein is a handle region, and a second span that is angled upwards from said first span. In the second span, a means for stimulating the Grafenberg area comprises one or more of a mechanical finger that oscillates in a reciprocal motion within a protuberance that protrudes from the dorsal surface of said second span. Thereby, the G-spot stimulating means will directly impinge upon the Grafenberg area when inserted into the vagina, while the precise angle and force of that interaction can also be finely adjusted.

Abstract: A method for making an acoustic wave device (500, 600, 701, 801, 901, 1001), and an acoustic wave device (500, 600, 701, 801, 901, 1001) made by the method. The method comprises steps of providing a substrate (11) capable of supporting acoustic wave propagation and disposing a first transducer (518, 518') thereon. Disposing the first transducer (518, 518') includes disposing first through fourth electrode groups on the substrate. The first group couples to a first electrical interconnection (17+). The second group couples to a second electrical interconnection (17-). The third group couples to a common electrical interconnection and is interleaved with the first group of electrodes. The fourth group couples to the common electrical interconnection and is interleaved with the second group.

Abstract: A method for making an acoustic wave device. The method has steps of providing a substrate suitable for acoustic wave devices and processing the substrate to provide a patterned metallization thereon. The patterned metallization includes an acoustic wave filter pattern. The method also has steps of measuring a sheet resistance associated with the acoustic wave filter pattern, determining a resistance of a test pattern associated with the acoustic wave filter pattern to provide a measured resistance and computing an estimated average linewidth for the acoustic wave filter pattern from the measured resistance and the sheet resistance.

Abstract: A full duplex radio (10) having improved properties is obtained by using asymmetric surface acoustic wave (SAW) filters (70, 92, 100, 100', 112). The filters (70, 92, 100, 100', 112) are composed of series (50.sub.1, 50.sub.1 ') and parallel (50.sub.2, 50.sub.2 ') coupled SAW resonators. Asymmetry is obtained by covering either of the series (50.sub.1, 50.sub.1 ') or parallel (50.sub.2, 50.sub.2 ') resonators of each filter (70, 92, 100, 100', 112) with a dielectric layer (96) to increase the SAW coupling coefficient (Cs, Cp) of the covered resonators (50.sub.1 ', 50.sub.2 ') relative to the uncovered resonators (50.sub.1, 50.sub.2). The filters (70, 92, 100, 100', 112) are desirably in pairs arranged with mirror image frequency asymmetry such that the steeper skirts (87, 79) of the frequency response (91', 91") are adjacent. Greater pass-band bandwidths (77, 77', 77") can be obtained without adverse affect on transmitter and receiver isolation.
