Abstract: A method of removing organic carbon and other contaminants from a water stream. The method comprises screening large solids from the stream. Pre-oxidation chemicals may then be added. A coagulant is fed into the stream. An activated carbon, preferably formed from lignite, is added by pumping a highly concentrated activated carbon slurry into the stream. The stream, including the activated carbon and coagulant, next flows into a clarifier, where the coagulant will flocculate and enmesh the activated carbon. The activated carbon adsorbs organic carbon and other contaminants, including bacteria, pharmacological agents, and hydrocarbons, as the stream flows through the clarifier. Eventually, the flocculate will agglomerate and settle out in the clarifier, where it, the enmeshed carbon, and the contaminants they contain may be removed. The stream's organic carbon content exiting the clarifier will be much reduced. Accordingly, less primary oxidizing agent will be needed to treat any remaining organic carbon.

Abstract: A polyvinyl halide compound has thermal conductivity and includes polyvinyl halide resin, natural or synthetic graphite of flake or spheroid form, and at least 0.5 weight percent of epoxidized vegetable oil. Selection of types and amounts of graphite and epoxidized vegetable oil provide thermal conductivity while other desirable properties of the compound are suitably maintained. The compound can be used for making any end use article that needs flame retardance and good thermal management and is especially useful as a thermally conductive material to replace die cast or extruded aluminum heat sinks in industrial applications, such as LED lighting fixtures.

Abstract: A flame retardant, flexible polyvinyl chloride mixture includes a trio of plasticizers and molybdate-based smoke suppressant for use in wire and cable articles.

Abstract: A polyvinyl halide compound, alone or alloyed with thermoplastic polyurethane, is used as a flexible layer for over-molding a rigid polymer substrate. Selection of types and amounts of calcium carbonate for the overmolding layer improves peel strength to achieve cohesive failure of the flexible overmolding layer rather than adhesive failure of the interface between the flexible overmolding layer and the rigid polymer substrate.

Abstract: Methods and systems for rapid and efficient development of content-rich customized e-learning programs. In some embodiments, the subject matter expert is presented with a variety of predetermined page types for potential use in teaching a topic. Based upon the page type selected, a storyboard template is provided defining points of a multimedia presentation, the template having guidance for the subject matter expert to fill in information related to the page type. The information can comprise text indicating what is to be displayed, what is to be spoken in a voiceover, and/or what action is to take place on screen. Based upon the content filled into the storyboard by the expert, multimedia animation templates that mirror the storyboard are then filled in and generated for use in an electronic learning format. The templates can be flash movies and can include graphics, animation, voiceovers, videos, interactive mouseover effects, and other rich content.

Abstract: The present invention generally relates to a method of thermally reactivating activated carbon via a two-step process: steam followed by pyrolysis; whereby the steam is preferably deoxygenated. Activated carbons reactivated by this method resemble their virgin counterpart's physical characteristics (e.g., BET surface area) and often perform better in water treatment. The present invention also includes a method of reactivating activated carbon via conventional processes (i.e. pyrolysis followed by steam) at low dissolved oxygen (DO) concentrations. The third aspect of the present invention is the activation of carbonaceous material comprising of steam treating the carbonaceous material followed by pyrolysis.
