Abstract: The process of the present invention is directed to a method for making zinc or zinc-aluminum alloy additions to galvanizing baths. The process involves addition of a wire of zinc or zinc-aluminum alloy introduced directly into a molten galvanizing bath to more rapidly achieve a desired zinc or zinc-aluminum chemistry thereby reducing the time required to make the bath addition.

Abstract: Novel polymers are provided having phosphonated and sulphonated substituent groups such that the polymer is multifunctional in its use. Optional amide substituents are used to reduce electrostatic charge density or for hydrogen bonding. An advantage of the polymer is the flexibility of using it for multiple purposes. A particular application is for bonding paper fillers and paper fiber together.

Abstract: A method of improving the brightness of calcium carbonate filled paper. The filled paper is dried and then bleached with an aqueous solution of a bleaching agent. The process may be used on all grades of paper that contain filler and is particularly useful in the bleaching of low brightness grade papers that are produced from mechanical pulp that contain calcium carbonate.

Abstract: The present invention relates to a product, a process for its preparation and the use of such in plastic film production. More specifically, the present invention relates to an antiblock talc, a process for the preparation of such and its use as an additive in the production of polyolefin film. Polyolefin films produced according to the process of the present invention are useful in a broad range of packaging and film covering applications.

Abstract: A process is disclosed in which coarse silica, calcium oxides and magnesium oxides are treated in a ball mill together with grinding aids and cold-strength binders. This material is then agglomerated with water to produce a product that reacts at elevated temperatures, e.g. in a fluidized bed reactor, to produce synthetic silicates.

Abstract: A metal alloy, such as steel, is manufactured in an electric arc furnace system equipped with at least one sensor, at least one a controller including a logic program and a variable valve in fluid communication with the furnace and a material source. The nature and quality of the slag formed over a molten metal during manufacture of steel is dynamically controlled by continuously adjusting the addition of one or more material to the arc furnace through the variable valve.

Abstract: A method is provided for producing a glass batch. The method involves use of a calcium magnesium silicate as a batch component substitution for a lithium melting aid. The amount used is effective to produce a beneficial viscosity character and reduced batch free time.

Abstract: A cored wire consisting of an inner calcium wire surrounded by an aluminum sheath forming a composite core which in turn is encased in a steel jacket. The cored wire is formed continuously by covering an extruded calcium wire with aluminum then inserting the aluminum covered calcium wire into a steel jacket in a roll forming process. Also disclosed is a method of reducing splashing when introducing calcium metal into a molten ferrous metal bath.

Abstract: Method and apparatus for concentrating slurries by removing liquid in a single effect unit maintained under vacuum to effect low temperature flashing of the liquid. The single effect unit is a single flash column with separate recirculation loops, one to preheat incoming slurry for concentration and a separate loop for withdrawal of concentrated slurry Vapor from the flash column can be treated to separate liquid from other components in the vapor.

Abstract: A method and apparatus for improving contact between a liquid and a reactant gas by moving the liquid in a serpentine path that moves horizontally and vertically through individual chambers or stations in an elongated tank or reactor and introducing a reactant gas into the liquid in one or more of the stations or chambers as the liquid moves through the tank or reactor.

Abstract: A synthetic silicate pellet is provided having component of calcium and magnesium, either together or in the alternative. Such pellet is further provided with either an aluminate silicate binder and/or an ion flow catalyst. The synthetic silicate pellet has use as a glass batch component.

Abstract: A product and a process for the preparation of discrete calcium carbonate particles that result from preparing an aqueous calcium carbonate slurry containing carbohydrates, carbonating the aqueous calcium carbonate slurry while maintaining the selected starting carbonation temperature. The product of the present invention is discrete particles of calcium carbonate which are especially useful in paints, plastics, paper coating, paper filling, and because of the purity level of the calcium carbonate particle may be used in cosmetics, pharmaceuticals and food applications.

Abstract: A method is disclosed of producing a synthetic silicate. The method is advantageous in providing material useful in glass making. Such method involves the reaction of calcium oxides and magnesium oxides, water and sodium silicates. The glass formation is performed at a lower temperature than usual and performed with a lower amount of volatile gas release. Less cristobalite formation in the glass occurs. The synthetic silicate produced can be a cylindrical pellet.

Abstract: A cored wire continuously formed by continuously inserting an extruded core inside a continuously roll formed sheath, the peripheral edges of the roll formed sheath joined by a continuous lock seam. Inspection of the partially formed lock seam at a designated process step serves to warn the user of malformed or defective lock seam portions in the finished cored wire.

Abstract: The present invention relates to an acid-stabilized calcium carbonate slurry having a pH of less than 7, preferably between about 6 and about 7, containing water, calcium carbonate, preferably precipitated calcium carbonate, and an acid-stabilizer of a water soluble calcium salt, a weak acid, a chelating agent, a weak acid capable of chelating calcium ion, or a mixture thereof. The acid-stabilizer is present in an amount sufficient to provide an aqueous calcium carbonate slurry having an increased calcium ion concentration and an acidic pH. In a typical acid-stabilized calcium carbonate slurry of the invention, the acid-stabilizer is present in an amount sufficient to provide a calcium ion concentration of about 1 millimolar to about 5 molar, preferably from about 1 to about 120 millimolar.
