Abstract: Precursor materials and methods of making are disclosed. The precursor materials include at least one of a silica source, and a carbon source, with or without liquid and a binder The methods described include pyrolyzing the precursor material to form a carbonaceous mixture and heat treating the mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen react with silica in the mixture to form carbides and/or nitrides. The carbides and nitrides formed from said methods may be used as blowing agents in a glass, ceramic, or metal forming processes or for promoting dispersion of the carbides and nitrides throughout a glass, ceramic, or metal composite.

Abstract: Carbides and nitrides are provided containing a controlled amount of pre-determined diluents and methods for their manufacture and use are disclosed. The pre-determined diluents include at least one of the silica, silicon metal, carbon, alumina, boron oxide, alkaline earth oxides such as calcium oxide, magnesium oxide, alkali oxides such as sodium oxide, potassium oxide, iron oxide, titanium oxide, and other components typically present in glass, ceramics, or metals. The carbides and nitrides with pre-determined diluents are formed by optionally pyrolyzing a precursor material to form a carboneous mixture and heat treating the carboneous mixture for a pre-determined time and at an elevated temperature during which carbon and/or nitrogen reacts with silica in the mixture to form carbides and/or nitrides and controlled amounts of pre-determined diluents.

Abstract: A bottom-up cocurrent combustion furnace for the production of synthetic microspheres by thermal expansion of glass particles is provided having improved characteristics with regard to anti-fouling, process efficiency, and yield. The disclosed furnace uses preheated combustion air to preheat the feed material and to convey the feed material in a dilute phase transport regime to a burner. The combustion air, fuel, and feed material are premixed prior to being injected though the burner. The feed material rapidly expands as it is ejected through the burner and through a flame and then rapidly cools to solidify the microspheres. Additional features are provided to prevent the furnace from fouling by keeping the feed material away from the furnace walls, removing feed material that adheres to the furnace walls, and collecting feed material that agglomerates or does not expand.

Abstract: Lubricating oil compositions providing superior soot dispersing characteristics, which contain a combination of a high molecular weight dispersant and a soot dispersant comprising a linked aromatic oligomer.

Abstract: The polymer matrix material includes a polymerization product of one or more monomers selected from the group of water-soluble, ethylenically-unsaturated acids and acid derivatives, and a crosslinking agent. A quantity of water is used for polymerization, such that the polymer material is swelled to a defined volume upon curing. Optionally, a water-soluble or water-swellable polymer and/or a chemical polymerization initiator.

Abstract: The use, in a minor amount, of a detergent composition comprising one or more metal detergents which comprises metal salts of organic acids, wherein the detergent composition comprises more than 50 mole %, based on the moles of the metal salts of organic acids in the detergent composition, of: (I) a metal salt of an aromatic carboxylic acid, or (II) a metal salt of a phenol, or (III) both a metal salt of an aromatic carboxylic acid and a metal salt of a phenol, in a lubricating oil composition for improving the oxidation resistance of the lubricating oil composition, wherein the amount of phosphorus and sulfur in the oil composition is less than 0.09 mass % and at most 0.5 mass % respectively, based on the mass of the oil composition. It has also been found that a detergent composition comprising more than 50 mole % of a metal salt of an aromatic carboxylic acid improves the reduction in wear in an engine.

Abstract: Low molecular weight Mannich base condensates of hydroxy aromatic compounds, an aldehyde; and an amine, wherein the combined number of substituent carbon atoms does not exceed 80. Such compounds are useful as soot dispersants in lubricating oils when used alone, or in combination with high molecular weight dispersants.
