Patent 8,697,220
Tape articles having improved properties are made from ultra-high molecular weight (UHMW) multi-filament yarns. The tape articles can have a ratio of the low temperature area under the curve (120.degree. C. to Tm-onset) to the total area under the curve (120.degree. C. to 165.degree. C.) of less than about 0.15 as calculated from an increasing temperature DSC scan from a temperature of 30.degree. C. to a temperature of 200.degree. C. at a constant rate of 10.degree. C. per minute. Additionally, in some examples the tape articles can also have a tenacity at least about 24 g/d (2.06 GPa) when measured by ASTM D882-09 at a 10 inch (25.4 cm) gauge length and at an extension rate of 100%/min. Further, the tape articles can have no long period of less than 450 Angstroms (.ANG.) when measured by small angle x-ray analysis.

Succinimide lubricity additive for diesel fuel and a method for reducing wear scarring in an engine
Patent 8,690,968
The present disclosure is directed to a hydrocarbyl-substituted succinimide lubricity additive or a hydrocarbyl-substituted succinamide lubricity additive for low sulfur diesel fuel. The additive is derived from an olefin having little to no terminal double bonds and a very high proportion of internal double bonds. The succinimide or succinamide is made by combining the alkylated succinic anhydride with ammonia. Also provided is a method for reducing wear scarring in a compression ignition engine comprising providing to the engine a middle distillate fuel comprising an effective amount of the hydrocarbyl-substituted succinimide and/or hydrocarbyl-substituted succinamide. A method for reducing an average coefficient of friction of a middle distillate fuel in a compression ignition engine comprising providing to the engine the disclosed fuel is also disclosed. Moreover, there is disclosed a method for improving the average film thickness from the combustion of a middle distillate fuel in a compression ignition engine.

Methods and compositions for improving gastrointetinal health
Patent 8,691,792
Methods for maintaining or improving the gastrointestinal health of animals susceptible to or suffering from poor gastrointestinal health by administering to the animal a gastrointestinal health maintaining or improving amount of a food composition comprising from about 1 to about 20% carbohydrate; from about 3 to about 10% total dietary fiber, wherein the total dietary fiber contains from about 10 to about 40% soluble fiber and from about 90 to about 60% insoluble fiber; and from about 0.1 to about 10% omega-3 fatty acids; wherein the composition has a digestibility coefficient of at least 80. Generally, the compositions are administered to the animal to prevent or treat diarrhea or to improve stool quality. Further, the compositions may be administered in conjunction with one or more probiotics, prebiotics, anti-gastritis drugs, anti-enteritis drugs, or anti-diarrhea drugs, microbial exopolysaccharides, or combinations thereof to maintain or improve gastrointestinal health.

Fuel additive for improved performance in fuel injected engines
Patent 8,690,970
A fuel composition for a fuel injected internal combustion engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a fuel-injected internal combustion engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt of a hydrocarbyl amine and a hydrocarbyl-substituted alkyl-hydroxybenzoate. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the fuel injected internal combustion engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt. The hydrocarbyl-substituted alkyl-hydroxybenzoate contains one or more hydrocarbyl substituents providing a total of at least 8 up to about 200 carbon atoms, provided the one or more hydrocarbyl substituents do not contain sulfur, oxygen, or nitrogen atoms.
