Abstract: The present invention is directed to film coating systems for use on oral dosage forms such as compressed tablets and orally-ingestible substrates which have improved pearlescent qualities. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat.

Abstract: A nonionic water-soluble cellulose ether is characterized in that when 3 pbw of the nonionic water-soluble cellulose ether is added to a mixture of 90 pbw of cordierite, 10 pbw of ordinary Portland cement, and 33 pbw of water, immediately followed by kneading at 20° C. and 20 rpm, a maximum torque for kneading is reached within 180 seconds from the addition. It is suitable as an admixture for extrudable hydraulic compositions. The hydraulic composition to which the inventive admixture is added can be kneaded within a brief time into a uniform mass which is smoothly extrudable.

Abstract: The invention relates to fiber compositions that can be pumped and metered in the fashion of fluid chemical admixtures into a concrete mix, thereby enabling the fibers to be dispensed by concrete ready-mix plant operators who can provide verification of fiber administration and dosage. The fibers, particularly plastic shrinkage control fibers having large cumulative surface area, are suspended in an aqueous medium such that their surface area is already wetted out, thereby virtually assuring that substantial uniform fiber dispersion can be achieved without clumping and the delay that is usually required by fiber intermixing.

Abstract: A composition and method for cleaning and conditioning a non-conductive surface defined by a through hole in a printed circuit board (PCB) is disclosed. The through hole surface is contacted with the composition of the invention to provide a cleaned and conditioned surface. The clean and conditioned surface is coated with conductive carbon particles (usually graphite) to provide a carbon-coated surface. The carbon-coated surface is electro plated and then soldered using hot solder. Those surfaces that have been soldered and also treated with the composition of the invention exhibit fewer blow hole problems. The composition of the invention comprises a cationic conditioning agent and one of a binder or an anionic dispersant that improve the adhesion and coverage of a coating containing graphite to a surface defined by a through hole bore or other substrate. (“Through holes” as used herein refers both to through holes and to vias.

The solution is wet milled to form an extremely fine particle size distribution of the gum. The composition is rapidly hydratable and useful as a stabilizing additive in many cement and drilling fluid applications.
