Abstract: The present invention is directed to a synthetic fuel made of coal dust, water and an organic chemical reactive with the coal dust to form a chemical bond with the coal dust upon compacting to provide a product very similar to coal. The inventive product surprisingly in some case provides higher BTU value than coal alone (up to 5 to 1000 BTU per ton more than counterpart coal), does not produce the waste ash at the users' facility of inorganic chemicals (and many organic chemicals such as tar) and can solve a moisture problem of coal dust and give even more increased green strength.

Abstract: This invention is of a composition comprised of a smectite clay modified with an organic chemical composition and a polymer. The composition consists of an organic chemical/smectite clay intercalate that has been ion-exchanged and reacted and intercalated with one or more quarternary ammonium compounds and an anionic material and further blended into a polymer resin to make a nanocomposite composition. This material can be blended into a wide variety of polymers. This kind of system gives improved dispersion over conventional organoclays, intercalates or hybrid clays described in the literature, especially in non-polar resins. The defined organoclay has been found to be highly dispersible in a variety of polymers, whether polar or non-polar.

Abstract: A clay slurry is described using smectite clay, water, and a defined phosphonate additive that is hydrolytically stable over time. The viscosity of the clay slurry remains pourable and relatively unchanged over time compared to prior art slurries. The slurry is useful to provide rheological control to paints and coatings and is particularly useful as an anti-bleed additive for concrete.

Abstract: Conventional organophilic clays, when used as rheological additives in oil based invert muds, display marked viscosity loses in the mud when these muds are heated much above 350° F., whereas muds prepared according to the present invention are dramatically more viscosity stable at temperatures through 500° F. The present invention relates to the discovery of oil based invert emulsion drilling fluids that provides more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional fluids containing organoclays. As a result, the inventive fluids of this invention are ideal candidates for high temperature applications. This invention in another aspect of this invention is a process for improving the rheological properties of oil well drilling fluids particularly useful for oil-based invert emulsion types of drilling fluids.

Abstract: An improved thickening composition for organic systems, including paints and coatings, is described. The additive provides paints and coatings more than adequate viscosity improvement without affecting intercoat adhesion characteristics.

Abstract: An anti-abrasion additive for ink formulations includes sintered polytetrafluoroethylene in a reduced amount; a petrolatum; and a high melting point microcrystalline wax. The additive, when dispersed in an ink, provides the ink with good slip, abrasion resistance, low misting, and mar resistance.

Abstract: This invention is of a drilling fluid composition containing a liquid thixotrope, which thixotrope is free of solvents or any other diluent, and is in easily usable, liquid form, pourable at ambient temperatures, and which provides effective and efficient rheological properties when used at low levels in such compositions. In a specific aspect, the invention provides an oil or oil invert emulsion drilling fluid composition containing one or more organoclays, and in addition contains a additive which comprises the reaction product of an alkoxylated nitrogen containing compound or a diamine, and one or more polycarboxylic acids in a specified equivalent ratio.

Abstract: The compositions described include micronized zinc oxide UV blocking agents with at least one organic UV protective compound. Premix compositions are provided for imparting improved UV resistance to paints, coatings, finishes and plastic articles comprising both micronized inorganic zinc oxide and organic UV protective compounds suitable for easy later inclusion into paint, coating, finish and plastic articles formulations.

Abstract: This invention is of a resin composition including an additive of one or more organic peroxide thermal imitators to cationic photoinitiators, that are sensitized with alpha-hydroxy-ketones, which composition provides a self-propagating thermal curing reaction first activated by a short duration of surface ultraviolet radiation. The thermal reaction is non-directional, thus eliminating the line of sight limitation of current radiation curing processes. Complete curing can be achieved of the composition in a very short time; often after only a few minutes or less. The activation period can be provided by only a few seconds of ultraviolet light using a wide variety of commercial ultraviolet light sources.

Abstract: A flexible capsule formed from a modified starch free of animal based gelatin. The invention provides a novel capsule defining a closed interior chamber, the capsule being formulated from a composition which is free of animal based gelatin comprising at least one plant based starch having been modified to have gelatin like properties; and a paint ball formulation, drug, vitamin, perfume or bath product contained within the capsule.
