Abstract: A fitting for sealingly and fixedly coupling to a component that includes a body having a first insertion end that defines a first end face and a cavity. The cavity has an interior surface. A first seal is adapted to engage a first component when the first component is inserted through the insertion end and into the cavity. The seal extends into the cavity from the interior surface of the cavity. A band of sealant is located about a perimeter of the cavity. The band of sealant is adapted to seal the interior surface and the first component. The body is crimped around the first component to secure the fitting to the first component and seal the interior surface to the first component.

Abstract: A method for providing purified air to an occupant of a seat in a mask lacking corporeal features that is generated by an apparatus. The apparatus includes a contaminant conditioning system that delivers purified air to a first and a second laminar flow generator. Each laminar flow generator produces a respective laminar flow that combines to form and fill a breathing space with purified air that envelopes an inhalation sphere of the occupant and inhibits air other than the purified air from entering the breathing space.

Abstract: An assembly having a fitting body, a structure, an annular cavity within the fitting body, a grip ring, a seal element, and a spacing element. The structure has an end that is received in the fitting body. The annular cavity is disposed within the fitting body between an interior surface of the fitting body and an exterior surface of the structure. The grip ring, seal element, and spacing element are disposed in the annular cavity in a side-by-side relationship. The grip ring includes a plurality of first teeth that engage the exterior surface of the structure. Both the seal element and the spacing element extend radially across a height of the annular cavity such that the seal element and the spacing element each contact and sealingly engage the exterior surface of the structure and the interior surface of the fitting body.

Abstract: A seal member for sealingly securing a first and a second pipe at a crimp connection, the seal member including a ring-shaped body having an outer diameter and an inner diameter. A plurality of protrusions are formed on the ring-shaped body and extend radially outwardly from the outer diameter. The ring-shaped body permits fluid to pass around adjacent protrusions prior to attaining the crimp connection and inhibits fluid from passing therearound subsequent to attaining the crimp connection.

Abstract: An assembly having a fitting body, a structure, a first seal element, and a grip ring. The fitting body has an insertion end that includes a mount and an abutting wall. The structure has an end that is received into the insertion end of the fitting body. The first seal element is received in the mount and sealingly engaged to the structure and the fitting body. The grip ring is received in the mount and includes a ring body and a plurality of first teeth that are resiliently coupled to a ring body. The first teeth are engaged to the end of the structure and the ring body abuts the abutting wall.

Abstract: An apparatus comprises an inlet capable of receiving air around a seat, a contaminant conditioning system, an outlet, and a fan system. The contaminant conditioning system may be capable of removing contaminants from the air to form conditioned air. The outlet may be capable of expelling the conditioned air around the seat. The fan system may be capable of drawing the air from a breathing zone through the inlet, moving the air drawn from the inlet to the contaminant conditioning system to form the conditioned air, and moving the conditioned air out of the outlet.

Abstract: Fusion promoters are described that combine a RNA polymerase III basal promoter and regulatory elements from RNA polymerase II regulatory regions, and which provide specific regulation of expression from the promoter. Such fusion promoters are useful, for example, for expressing RNAi agents in vivo.

Abstract: Hydrogen sulfide is removed from a water-in-oil emulsion by treatment of the emulsion with sulfur dioxide to convert the hydrogen sulfide to elemental sulfur. The elemental sulfur formed is distributed between the oil phase and the aqueous phase of the emulsion.

Abstract: The method of recovering petroleum from a subterranean reservoir preferably comprising the steps of: (1) introducing through an injection well a predetermined amount of a polyalkylene oxide adduct of a fusible, aromatic hydrocarbon soluble synthetic resin which contains between about 4 to about 16 phenolic groups and is a condensate of a substituted phenol and an aldehyde, said condensate resin being further condensed with ethylene oxide and at least one other alkylene oxide containing 3 or 4 carbon atoms and in such amounts that the weight ratio of condensed alkylene oxide moiety to phenolic resin moiety ranges from about 1-to-1 to about 100-to-1 and the weight percentage of ethylene oxide residues to the total of all alkylene oxide residues ranges from about 20% to about 75%; said adduct (a) being soluble in water to the extent of about 1% or more at 25.degree. C. and (b) said 1% solution having a cloud point of less than about 70.degree. C.

Abstract: Processes for plugging oil producing formations, fluid thief formations and the like in oil wells and compositions for the same are disclosed.

Abstract: This invention relates to novel polyurethane prepolymers which consist essentially of the reaction product of a polyoxyalkylene polyol having a critical oxyethylene content and an isocyanate constituent, the reaction product having a defined level of free NCO. Particularly useful prepolymers are produced using a tolylene diisocyanate residue. The prepolymers provided have outstanding utility for rebonding polyurethane foams for applications such as, for example, carpet underlays and allow significant reductions in the adhesive level used in forming such rebonded foams and in the demolding cure times in comparison with presently used prepolymer adhesives. The prepolymers are also useful for applications in which polyurethane prepolymers are used presently such as, for example, in hydrophilic foams.
