Abstract: A process to reduce the hydrogen sulfide content of a hydrogen sulfide-containing subterranean formation and of products recovered from the subterranean formation by injecting sulfur dioxide into the subterranean formation.

Abstract: A method for producing sulfur and energy from an acid gas stream containing hydrogen sulfide by partially combusting the acid gas stream to produce a combustion product gas, mixing a sulfur dioxide stream with the combustion product gas, separating sulfur from the mixture, combusting sulfur to produce sulfur dioxide and heat energy and passing at least a portion of the sulfur dioxide to the combustion product gas.

Abstract: A method and apparatus for managing how threads of a multi-threaded computer program share a resource is provided One thread of the program is given priority over other threads of the program by granting to the thread possession of the lock associated with the resource regardless of whether the thread currently requires use of the resource. The other threads are designed to indicate to the priority thread when they require use of the resource. If the priority thread is done using the resource and detects that another thread is waiting to use the resource, the priority thread releases the resource lock for the resource. After releasing the lock for the resource, the priority thread automatically requests the resource lock. After using the resource, any non-priority thread releases the resource lock to the priority thread if the priority thread has requested the resource, without regard to whether any other threads may be waiting for the resource.

Abstract: An electrodeposition process using an aqueous coating composition comprising a carbamate-functional crosslinking agent and at least one principal resin is described. The carbamate-functional crosslinker is formed by first reacting a polyamine having at least two primary amine groups and at least one secondary amine group with a cyclic carbonate, and then reacting the product of the first reaction with a polyepoxide compound.

Abstract: The present invention relates to an aqueous powder coating dispersion based on epoxy resins and phenolic curing agents or carboxyl-containing polyesters for the coating of packaging containers, which dispersion consists of a solid, pulverulent component I and an aqueous component II, component I being a powder coating which containsA) at least one epoxy resin having an epoxide equivalent weight of from 300 to 5500 andB) at least one curing agent having more than one phenolic hydroxyl group per molecule and a hydroxyl equivalent weight, based on phenolic OH groups, of from 100 to 500, preferably from 200 to 300, orC) at least one polyester having an acid number of from 25 to 120 mg of KOH/g and an OH number >10 mg of KOH/g, andD) at least one epoxy resin having an epoxide equivalent weight of from 400 to 3000, and component II being the aqueous component of the dispersion which contains at least one nonionic or anionic thickener.

Abstract: The invention relates to a novel electrocoating composition for metallic substrates that exhibits "thick-build" protective properties at "medium-build" thicknesses. It is composed of a self-addition epoxy resin-polyamine adduct, a blocked isocyanate cross-linker, a polyglycol-polyamine grind resin, a plasticizer, an anti-cratering agent and pigments.

Abstract: The present invention relates to a thermoset powder coating composition and method of application. The coating includes a copolymer having a reactive functionality selected from the group consisting of epoxy, carboxy, and hydroxy functionalities and mixtures thereof, a suitable crosslinking agent capable of reaction with the reactive functionality on the copolymer, and an aliphatic or aromatic crystalline, hydroxyl containing compound having a melting point of between 30.degree. C. and 150.degree. C. and a flow control agent. The powder coating is a pigmented or clear coat powder composition applied over a primer layer.

Abstract: The viscosity of heavy oil may be incrementally reduced over what can be achieved by steam alone, by introducing an aqueous metal salt solution into a reservoir undergoing steam injection. The metal ion is selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo and Al. In a preferred feature CO is also introduced as a second additive, with a further oil viscosity reduction being observed with certain of the metal ions.

Abstract: A rack for supportively mounting a solar collector to a mounting surface to set the angle of tilt with respect to the sun. One end of the rack is adapted to provide predominant support of the collector, while the other end is height adjustable to provide the proper angle and to accept tension and/or compression due to wind leading.

Abstract: A cup-shaped member having cylindrical sides for coupling adjacent ends of headers of solar collectors of the liquid heat-exchange type, or a header to an associated manifold. The member has a cylindrical body and an orifice in the base through which liquid flows. Several arrangements for using the member to couple the headers together or to a manifold are disclosed.
