摘要： One or more rigid sealing segments are attached to pipe end sections and the assembly lined to form a fluid-resistant joint. A segment surface forms the primary sealing interface of lined pipe sections without the need for a conventional removable liner edge seal. The lining process and configuration sealably bonds the liner to the fluid-resistant sealing segment and to the non-fluid-resistant pipe. The manner of bonding both avoids (or limits) liner stress and covers the non-fluid-resistant material of the pipe. In an alternative embodiment, the sealing segments are engaged at mating threaded surfaces, the mated threads providing a single primary sealing and engagement interface. Redundant liner end sealing may also be accomplished by a sandwiched deformable material if added reliability of sealing harsh fluids is desired. In another embodiment, portions of the rigid sealing segments are slidably mounted relative to each other and the primary seal interface is temperature actuated.

摘要： A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture is composed of inorganic cement particles, a liquid styrene mixture and a minor amount of one or more poly-olefinically unsaturated co-monomers. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferably selected from a group including trimethylolpropane-trimethacrylate, divinyl benzene, hexadiene, and polyvinylsiloxanes. Mixing the liquid and solid components forms a slurry which is transferred to a pipe interior. Transfer properties can be controlled by particulate gradation, dissolved polymers, and rheology control additives. The pipe is then spun to centrifugally cast the liner. The composition avoids the need for high temperature curing and toxic reactive unsaturates to co-polymerize and cross-link polystyrene. Like the current polymer concrete materials, the materials embodied in the present invention have adequate strength at geothermal operating temperatures and reduced permeability, but they achieve this result without either a significant loss of broad spectrum chemical resistance to harsh geothermal environments or a large increase in cost. Other embodiments also incorporate the use of pozzolanic solids and high alumina cement to further improve chemical resistance characteristics.

摘要： A polymer concrete pipe liner is formed from a fluidized, but substantially waterless cement containing mixture applied to the pipe interior. The mixture contains inorganic cement particles, a liquid styrene mixture and one or more poly-olefinically unsaturated co-monomers in a greater amount than the styrene. The mixture substantially excludes acrylonitrile and acrylamide. The co-monomers are preferably selected from a group including trimethylolpropane-trimethacrylate, trimethylolpropane-methacrylate, divinyl benzene, and hexadiene. Mixing liquid and solid aggregate components forms a slurry which is transferred to a pipe interior and centrifugally cast to form the liner. The composition avoids the need for high temperature curing the toxic reactive unsaturates to co-polymerize and cross-link polystyrene. A preferred embodiment incorporates the use of relatively high concentrations of cement material, usually above about 40 weight percent of the aggregate component of the mixed slurry, to further improve chemical resistance and strength characteristics.

摘要： A concrete pipe liner is formed from a difficult-to-compact hydraulic cement slurry applied to a pipe interior. The slurry contains inorganic non-compactible hydraulic cement particles, a concrete superplasticizer component, water, and optionally and preferably filler particles. The pipe is then spun to centrifugally cast a stronger, denser pipe liner than a comparable liner containing no superplasticizer.

摘要： A differential analysis method can be used to determine the presence or absence of a fluid in contact with a tubing string within a wellbore. The method uses a signal generator and detects tubing-perturbed signals, searches for an initial interfacial indicator within a window, axially aligns indicators within a data series as the detector traverses the tubing, discerns an adjacent interfacial indicator known to be incrementally changed by the presence of the fluid, and compares the adjacent indicators to the known incremental change. Even if the absolute location or condition of the interface is uncertain, the relative change indicates the presence or absence of fluid. A prior condition indicator can also be used to determine a second window for detecting an adjacent surface signal indicators. The arbitrary or prior condition baseline avoids the need to "know" the actual properties of intervening materials currently required for analysis of casing conditions and some of the extrapolation limitations inherent in current analysis methods. The method can also achieve accurate results by iterating on the initial indicator.

摘要： A system for repairing a tear in the meniscus in the knee joint including a suture having a first leg, a second leg spaced from the first leg and a cross member connecting the first and second legs. An instrument for delivering the suture to the meniscus can be inserted through an incision in the knee and into the vicinity of the meniscus. A first end of the instrument enters the meniscus adjacent to a first side of the tear, passes through the meniscus and exits the meniscus on a second side of the tear in the meniscus generally opposite the first side of the tear. The instrument has a channel extending longitudinally of the instrument in which the first leg of the suture can be inserted. A push rod pushes the first leg and cross member generally lengthwise in the channel and into the meniscus where the suture closes the tear.

摘要： The present invention is an interface between a piece of baggage and a preconcentrator. The baggage-preconcentrator interface is able be secured to the opening in the baggage, such as an opening created by a zipper. The baggage-preconcentrator interface provides a convenient entry point from which to extract air from the interior of baggage. The shape of such interface corresponds to that of the preconcentrator, which collects constituents of air. The preconcentrator is inserted into the baggage-preconcentrator interface and an air sample is extracted from the interior of the baggage and through both the interface and the preconcentrator. As the air is extracted, the constituents of air collect in the preconcentrator. After collecting the constituents, the preconcentrator is inserted into a testing unit capable of detecting trace amounts of explosives, such as an ion trap mobility spectrometer. The testing unit analyzes the constituents and determines whether any of them are explosive.

摘要： Single or multi-piece, pipe joint seal elements have at least one slidable interface that contacts a sealing surface of an end ring attached to a cementitious pipe liner. The slidable interface allows for slippage between seal pieces and/or seal piece-end ring surfaces during pipe joint assembly and disassembly. The end rings help distribute and minimize rotational and other stresses exerted upon the liner end surfaces and seal pieces. Such end ring surfaces further provide a quality surface for the seal element to effect a seal. The slidable interface seal is especially useful for joining brittle-lined pipe sections handling harsh fluids such as geothermal brine, etc.
