Abstract: A process for producing a corrosion-resistant coating on magnesium includes subjecting a magnesium article to a bath of a non-aqueous molten salt without the application of a potential. An aluminum counter electrode may be in contact with the molten salt.

Abstract: A process for producing partitioned packages by which a first film is formed into an elongated inner tube and a second film is formed into an elongated outer tube surrounding the inner tube. Reactive components are filled into the inner and outer tubes as the tubes are formed to maintain the reactive components separate from each other. Only the outer tube is actively engaged to advance the tube longitudinally. Frictional forces from the advancing outer tube are applied to the component within the outer tube and, in turn, are applied to the inner tube thereby advancing the inner tube at a rate substantially the same as the outer tube.

Abstract: A composite material is disclosed having a matrix formed of polyethylene terephthalate and cement particles distributed in the matrix. The cement particles may be Portland cement. About 50 wt % or less of the composite material is cement particles. The cement particles have an average particle size of no more than about 100 ?m.

Abstract: A nut having an injection-molded insert or delay stopper is threaded onto an end of an anchor. A capsule containing a resin component and a catalyst component and the other end of the anchor are positioned in a bore hole in a mine roof, mine wall, side of a hill, concrete wall, or concrete floor. The threaded end of the nut contacts the insert and rotation of the nut rotates the anchor, breaking the capsule and mixing the components. After the components set, increased torque is applied to fracture the insert and move the nut up the threaded end of the shaft against roof stabilizing components on the shaft.

Abstract: This invention relates to a process for converting silica to polysilicate gels or hydrogels by combining an aqueous silica source with a CO2 feed stream as the gel initiator, whereby the reaction stream is propelled at high velocity and turbulence maintaining the CO2 uptake rate in the reaction stream. The invention also relates to a process for converting silica to polysilicate by pre-carbonating water at pressures of equal to or greater than 100 psig before initiating the polysilicate reaction.

Abstract: Devices and related methods are provided for irradiating a portion of a body. A device according to one embodiment can include a radiation needle, a fluorescent target, and an x-ray transmitting window. The radiation needle can include a radiation conduit having a first and second end for passing primary x-rays. An x-ray generator can generate the primary x-rays and pass the primary x-rays from the first end to second end. The fluorescent target can connect to the second end for absorbing the primary x-rays and produce by fluorescence secondary x-rays for irradiating a predetermined portion of the body. The fluorescent target having a surface for absorbing the primary x-rays to fluoresce and emit said secondary x-rays. The x-ray transmitting window can be positioned adjacent to the fluorescent target such that the secondary x-rays exit through the x-ray transmitting window. The secondary x-rays can irradiate target tissue within the body.

Abstract: The invention is related to a coating delivery system that includes at least one pressure vessel having an inner surface, a flexible bladder disposed in a first pressure vessel and having an open condition and a closed condition, an internal region disposed between the inner surface and the bladder, and a deliverable substance including a coating component interspersed with at least one of liquefied carbon dioxide and supercritical carbon dioxide. The deliverable substance is disposed in one of the flexible bladder and the internal region, and the pressure-conveying fluid is received in the other to exert pressure on the deliverable substance and thereby permit transport thereof when the flexible bladder is in the open condition.

Abstract: A mine support includes an elongate metal member and a coating comprising post-consumer recycled thermoplastic disposed on the member. The thermoplastic may include post-consumer recycled poly(ethylene terephthalate), and the coating may be an injection molded coating. A first layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 16% and about 30%, and a second layer of the coating may be provided with a thickness at least about 0.1 mm and a crystallinity between about 6% and about 14%. Either the first layer or second layer may contact the elongate metal member.

Abstract: The invention is related to a coating delivery system that includes at least one pressure vessel operable in sealed and unsealed conditions, a deliverable substance including a coating component interspersed with at least one of liquefied carbon dioxide and supercritical carbon dioxide, and a pressurizing fluid. The deliverable substance is disposed in a first pressure vessel of the at least one pressure vessel, and the pressurizing fluid directly exerts a pressure on the deliverable substance to effect transport thereof when the pressure vessel is in the unsealed condition. The deliverable substance may be spray discharged.

Abstract: A surgical instrument comprising a housing with a motor and source of power contained in the housing. A removable sheath is placed over the housing and a cutter assembly is removably mounted to the housing so that the housing is protected from external materials and contamination. The cutter assembly has a body, a tube projecting from the body, a blade positioned in the tube and a drive transfer mechanism mounted in the cutter body, connecting the blade to the motor. The tube defines an aperture and the blade in combination with the walls defining the aperture shears tissue entering the hole. A second passage is formed in the cutter body communicating with the tube to allow pressure differentials to be exerted to the tube.
