Abstract: This invention relates to an improved process for casting a metal by pouring molten metal into and around a casting assembly, where a riser containing a sleeve is a component of the casting assembly. The process comprises (a) inserting a riser insert into the cavity of the riser containing the sleeve, and (b) then allowing molten metal to flow into the cavity of the riser containing the riser insert. The density of the riser insert is such that the riser insert floats on the surface of the molten metal when the molten metal enters the cavity of the riser and provides a thermal barrier to reduce heat loss from the riser. The sleeve is shaped such that the riser insert will not be forced out or float off of the riser cavity when the metal is poured.

Abstract: UV curable, liquid, oligomeric compositions are prepared from the reaction product of a Michael addition oligomer and an isocyanate capped polybutadiene.

Abstract: The invention relates to a method for producing anionic water-in-water polymer dispersions containing at least one finely dispersed, water-soluble and/or water-swellable polymer A and a continuous aqueous phase. This phase has a partial quantity of at least one polymeric dispersing agent B in which monomers dispersed in this aqueous phase are subjected to a radical polymerization, and after the polymerization is completed, the reaction mixture is subsequently diluted with the remaining amount of dispersing agent B.

Abstract: This invention relates to an automated process for efficiently treating an aqueous system with chlorine dioxide. The process results in high efficiency yields of chlorine dioxide on a continuous basis by minimizing the waste of precursor chemicals. Additionally, the process creates less environmental stress because the formation of unwanted by-products is minimized. The level of chlorine dioxide in the aqueous system treated and other parameters of the process are monitored and adjusted automatically to maintain them within acceptable levels.

The invention further relates to a resin emulsion and a mother paint comprising an aqueous emulsion of the polyester resin, a two-component water-based paint system, comprising the resin emulsion or the mother paint and an isocyanate component as well as a method for the preparation of the water-based paint system.

Abstract: A method for reducing the consequences and risks of failure in a hydrocarbon pipeline system includes identifying specific segments of pipelines the leakage of which could have an adverse impact on environment or safety, particularly in areas of high consequence, developing a baseline assessment plan for such segments by analyzing information including age, corrosion, and types of seams and joints and then establishing preventive and migitative measures including, where necessary, positioning emergency flow restricting devices in one or more pipeline segments.

Abstract: The invention detailed herein comprises a family of multifunctional acrylate oligomers which are useful as pigment grinding vehicles for use in radiation-curable coating formulations. The multifunctional acrylate resins are formed by the reaction of acrylate monomers and oligomers with ?-keto esters (e.g., acetoacetates), ?-diketones (e.g., 2,4-pentanedione), ?-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ?-dicarbonyl compounds or Michael “donors” that can participate in the Michael addition reaction. These resin vehicles have a built-in chromophore that enables ink formulations made from their dispersions to cure under standard UV-cure conditions with significantly less photoinitiator than commercial formulations. The resins also exhibit excellent pigment wetting characteristics and can be designed to function as a single dispersion vehicle for different pigments and different ink applications such as screen, flexographic, and lithographic printing.
