Abstract: A method for obtaining particulate calcium carbonate exhibiting improved brightness and color and having uniformity of size such that when the particles are formed in the causticization process in a kraft pulp mill, the time required to separate the particles from liquors in which they are suspended is minimized and the amount of liquor recovered is maximized, with minimal dilution by water used for washing. The method includes the steps of a) slaking calcium oxide in water or an alkaline liquor containing as dissolved species predominantly sodium hydroxide; b) mixing the slaked lime with green liquor from a kraft pulping process to complete a causticization reaction that produces white liquor and lime mud; c) separating the lime mud from the white liquor; and d) milling a portion of the lime mud for use as a white mineral pigment in applications where such pigments are typically used.

Abstract: A method and system for dispensing an additive wire involves use of a lance for delivering the additive wire and determination of location data with respect to a surface of a metallurgical melt into which the lance is placed.

Abstract: The amount of elongation of a workpiece during forging can be determined by image processing to calculate the total amount of horizontal movement of marked patterns such as forging scale on the ends of the workpiece which move away from a forging bite during the forging blow. Images of marked patterns before and after a forging blow on both sides of the bite of a forging die are compared to determine the movement of the marked patterns and thus the movement of the ends of the workpiece. A method and system of determining the elongation and vertical displacement of a workpiece during forging is disclosed.

Abstract: A dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine and then surface treating the ground calcium carbonate with a dispersant and the method of making the same is disclosed. Dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine such as triethanolamine and then surface treating the ground calcium carbonate with a dispersant such as sodium polyacrylate when added to a polyester polymer composition yields a lower viscosity of the polymer system than without the addition of triethanolamine followed by surface treating the ground calcium carbonate with a dispersant.

Abstract: A lance for feeding an additive wire into a quantity of molten metal below the surface of the molten metal. The lance has an inlet end which receives additive wire and an outlet end which dispenses the additive wire. The lance has an exterior sleeve of cardboard which has an inner surface. A portion of the inner surface of the exterior sleeve contacts an interior sleeve made of a refractory material. At the inlet end of the lance is a cardboard inlet outer sleeve and a cardboard inlet inner sleeve inside of the outer sleeve. The lance can have a coupling for fitting to a wire feeding apparatus.

Abstract: An apparatus for the applying of refractory material in 360 degrees while the apparatus is raised or lowered vertically or inserted and retracted horizontally can apply a layer of material continuously on the interior surface of a hot vessel. Wet mixed refractory material is supplied to an applicator and pressurized air is supplied to the applicator so as to rotate a spinner head on the applicator. The apparatus includes a shroud around the housing of the applicator which conveys the pressurized air around the housing to cool the housing below the temperature of the vessel. Also described is a method of applying refractory material by a spinner head on the applicator in the form of a spray to hot metallurgical vessels such as the snorkel tubes of vacuum degassers and ladles.

Abstract: The composition applied to the refractory structure has a magnesia-based refractory material, calcia source and a binder. After application of the refractory material to a refractory structure and upon application of heat to the applied refractory material a matrix is formed which protects against penetration of the slag into the refractory material. The resulting refractory material has improved hot strength, slag resistance and durability.

Abstract: A method of blending a fine precipitated calcium carbonate (PCC) filler with larger PCC, the resulting blend to be used alone or in conjunction with a ground carbonate, clay or other filler, resulting in improved porosity by the lowering of the porosity of supercalendered paper, thereby imparting improved and offset printability. The fine PCC can be ultrafine PCC filler which then is blended with other fillers including but not limited to pigments. These fillers which are blended with the fine PCC include commercial and experimental PCC and commercial clays. Ultrafine PCC has agglomerates of small, discrete particles. Ultrafine PCC for use in the invention has a specific surface area of about 20 m2/g as measured by BET gas adsorption. As measured by a sedigraph, the average size of these agglomerates is from 0.4 to 1.1 microns.

Abstract: A method and system for measuring wear in the lining of a vessel in which undirected radiation signals are transmitted by at least two transmitters at known positions to a receiver at the device for measuring wear. The distances between the transmitters and receiver are determined based on the time of flight of the radiation between the transmitters and receiver. The location of the receiver at the measuring device is determined to be at a point on an arc of points at the distance calculated based on the time of flight of the signal from each of the transmitters to the receiver. The receiver is determined to be at the intersection of the two arcs of points at the distance calculated based on the time of flight of the signal from the each of the transmitters.
