Abstract: The invention relates to a process of coating inorganic particles with organic compositions, and agglomerating, compacting and heating of the coated particles into granules. Coating and compacting the agglomeration may be conducted continuously, and may be used to form granules having sizes ranging from about 1 to about 200 mesh. In one embodiment, these particles can be used to purify drinking water by removing heavy metals such as arsenic, lead and mercury and to remove or kill microorganisms in the drinking water, air and gas.

Abstract: The invention relates to methods and compositions for removing contaminants from edible cooking oils. Reduction in the accumulation of contaminants such as polar materials, free fatty acids, metals, color bodies, and soaps is achieved by treating the oil with a composition containing effective amounts of silica, acidic alumina, clay and citric acid. Removal of contaminants from oil according to the methods and compositions of the invention improves the quality of the oil and reduces costs as well as various health and safety concerns associated with the production of fried foods.

Abstract: A composition of matter useful particularly as a desoldering flux is disclosed. In some embodiments the invention combines a "low solids" flux normally provided for automatic wave and other soldering equipment with additional naturally-occurring rosin to create a composition capable of use with copper desoldering braid and manual desoldering operations.

Abstract: A pharmaceutical tablet is provided herein having an effective dissolution rate. The tablet contains a pharmaceutically-active ingredient and a substantially linear, i.e. non-crosslinked K-30 to K-120 PVP as a binding agent. The PVP used herein is made by an initiated polymerization process in which vinyl pyrrolidone monomer is polymerized in the presence of an initiator which produces a linear PVP polymerization, i.e. is a poor hydrogen abstractor of PVP polymer backbones, which would produce a disadvantageous crosslinked PVP product. Suitable initiators include low energy peroxyester free radical initiators, such as t-amylperoxy pivalate, an azo initiator, or a redox initiator which can perform at low temperatures.Preferably the residual initiator level in the PVP is reduced to less than 500 ppm, thereby further precluding the possibility of crosslinking of the PVP polymer during the shelf-life of the tablet.
