Abstract: A coal gasification nozzle is disclosed having a barrier, integral with the face of the injector, that fits into a groove of a heat shield attached to the nozzle face. The barrier prevents oxidative corrosion of the shield, and subsequent damage to the underlying face of the feed injector, by preventing diffusion of corrosive species to the threaded ring by which the heat shield is attached to the face of the nozzle. The life of the injector, and thus the length of any single gasification campaign, is thereby extended.
Abstract: A consumer article comprising a hand-held spray container, and a sprayable composition contained within the spray container comprising ethanol or isopropanol and methyl acetate or t-butyl acetate, a hair care composition comprising a fixative, ethanol, and methyl acetate or t-butyl acetate, and a method of fixing hair comprising spraying the compositions of this invention onto hair.

Abstract: A food wrap formed from polyvinyl chloride, at least one stabilizer, and a plasticizer in an amount of 10-60 parts per hundred parts polyvinyl chloride. The plasticizer may be present in an amount of 30-55 parts per hundred parts polyvinyl chloride. The plasticizer includes dioctyl terephthalate. Dioctyl adipate or another plasticizer may be used with dioctyl terephthalate. In this case, the plasticizer may contain 20 to 80 wt. % dioctyl terephthalate, or more specifically 20 to 60 wt. % dioctyl terephthalate. The food wrap may have a thickness of 1 to 80 mils. According to a method of wrapping food, the food wrap is applied to a food article. According to a method of forming the food wrap, polyvinyl chloride is combined with the plasticizer to form a mixture. The mixture is heated and fused. Then, a film is formed from the fused mixture.
