Abstract: Mounting rings and methods for mounting structures to shafts are provided. The rings and methods may be used to mount other rings or housings to a shaft. The rings are characterized by having flexible inner diameters that can deflect under a radial load. The radial deflection of the inner diameter permits the rings to deflect and engage an outer diameter of a shaft. The engagement of the rings with a shaft provides at least some resistance to the rotation of the shaft relative to the ring and structure. In one aspect, the ring is substantially rigidly mounted to the shaft. The ring may include a plurality of indentations, such as slots, on the inside diameter of the ring. These indentations may relieve at least some of the circumferential stress created by the radial deflection. Methods for using the rings to mount a structure to a shaft are also disclosed.

Abstract: A metal ring gasket provides a high-pressure temperature tolerant metal-to-metal seal between subcomponents of a threaded union. The metal ring gasket is received in an annular cavity formed between mating surfaces of the subcomponents of the threaded union. The metal ring gasket is capable of maintaining a fluid seal even at very high temperatures resulting from direct exposure to fire. At high fluid pressures the metal ring gasket is energized because hoop stress induced by the fluid pressure forces the metal ring gasket into tighter contact with the subcomponents of the threaded union.

Abstract: Generally speaking, in accordance with the invention, a putty is provided that can include many or all of the handling characteristics of a traditional plumber's putty, but with reduced staining qualities. Such putty can facilitate substantially stain free installations. Putties in accordance with the invention can contain combinations of polymers or oligomers, solvents, fillers and optional rubbery materials. A composition according to the invention is preferably sufficiently stain-free to be used on porous stone, such as marble and granite, without damaging the appearance of the stone. This is achieved by eliminating oil completely, or at least substantially, or restricting their ability to cause stains sufficiently. Because compositions of the invention can be made to be free of oils, they can also have the effect of eliminating the greasy feeling to the hands, which can occur when handling traditional putty.

Abstract: The invention relates to methods of sealing of pipeline joints operating with cryogenic liquids. The method is realized with the use of a tape of a porous structuring material that may be dry or impregnated with a liquid having a freezing point above the temperature of a cryogenic fluid in the pipeline. The material of the tape and the impregnating liquid are inert to the cryogenic fluid and to the environment. The method consists in that prior to filling the pipeline with the cryogenic fluid, the tape is tightly wrapped around the joint or an area that is at risk of a damage or puncture, the wrapping is then wetted by pouring on it the same liquid that was used for impregnation, and then the cryogenic fluid is fed to the pipeline for freezing the liquid that is contained in the tape for forming a tight frozen seal around the joint.

Abstract: An improved exhaust pipe flange ring gasket is principally defined by a pair of mating exhaust pipe flanges. One of the flanges has an annular groove extending in the one of the mating flanges. One or more metal Belleville spring washers or wave spring washers are wrapped within a stainless cover to define a hoop-style spring ring disposed within the groove. The metal washer replaces a traditional spiral wound core or graphite filler that tends to oxidize at high operating temperatures; such oxidation adversely affects sealing performance. Conversely, the washer, which can be either a Belleville or wave spring, is comprised of a hard stainless steel that will not oxidize at high operating temperatures. Gasket sealing performance is vastly improved, even though the Belleville or wave spring washer is relatively inexpensive. The Belleville or wave spring washer provides relatively stiff spring resilience to accommodate deflection along its axial compressive direction.
