20140322442 | CALCIUM ENRICHED REFRACTORY MATERIAL BY THE ADDITION OF CALCIUM CARBONATE - 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. | 10-30-2014 |
20140140176 | LOCAL POSITIONING SYSTEM FOR REFRACTORY LINING MEASURING - 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. Also, the orientation of the measuring device relative to the known positions of the transmitters can be determined if a second receiver is present at or near the measuring device and receives signals from the transmitters based on the positions of the receivers relative to each other at the measuring device. | 05-22-2014 |

20130251239 | SYSTEM AND METHOD FOR WORKPIECE MEASUREMENT DURING FORGING BY IMAGE PROCESSING - 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. | 09-26-2013 |
20130129601 | LIME CAUSTICIZATION PRODUCT BRIGHTNESS IMPROVEMENT VIA PRE-SLAKING - 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. | 05-23-2013 |
20130116372 | METHOD FOR PRODUCING DRY GROUND CALCIUM CARBONATE FOR USE IN THERMOSET POLYESTER RESIN SYSTEMS - 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. | 05-09-2013 |

More particularly, the invention is directed to a setting agent accelerator for use with an ultra-low cement , low cement and regular castable refractory material for preserving or maintaining the safety lining and the working lining of refractory structures or linings from mechanical erosion and/or attack by corrosive materials such as those produced during manufacture of cement, lime, metals or metal alloys including acid and basic slags. The setting agent accelerator has a set accelerating amount of sodium nitrate, sodium nitrite or mixtures thereof, calcium hydroxide and water. | 10-04-2012 |
20110235052 | SYSTEM FOR MEASURING THE INNER SPACE OF A CONTAINER AND METHOD OF PERFORMING THE SAME - A system and method for measuring the inner space of a container provides for the measurement of the wear of the lining of a container such as a torpedo ladle optionally while the ladle is still hot. The interior lining of the container is scanned by a scanner head from a first position in the container which is at an angle relative to the vertical axis of the container. The scanner head is placed in a second position in the container at an angle relative to the vertical axis of the container and from the second position the scanner head scans the portions of the interior lining of the container which were not scanned during the first position scan. By comparing the scanning measurements of the lining from the first position scan and the second position scan after the container has been loaded and unloaded with an initial reference measurement of the lining the wear of the lining can be measured. | 09-29-2011 |
20100315783 | HEAT SPREADER AND METHOD OF MAKING THE SAME - A heat spreader having at least two adjoining strips of pyrolytic graphite material is made by cutting a strip from a sheet of pyrolytic graphite in the z direction. Thermal conductivity in the xy plane of the graphite sheet is greater than in the z direction. The z direction cut provides strips which are then each individually oriented 90 degrees such that the thickness direction of the original pyrolytic graphite sheet becomes the width or length of the cut strip. A face on the side of a first strip adjoins a face on the side of a second strip. Due to the greater thermal conductivity in the xy plane of the strips as compared to in the z direction heat transfers more rapidly in the length and thickness direction of the strips than across adjoining sides of the oriented strips. | 12-16-2010 |

20100120945 | METHOD OF PRODUCING PIGMENT SUSPENSIONS - A method of producing a stable aqueous dispersion of a latex, solid particles and a dispersing agent, comprising contacting the latex with an anionic dispersing agent to form a modified latex, feeding the modified latex and the solid particles to a zone of high shear forces, and simultaneously subjecting essentially all of the modified latex and the solid particles fed to said zone to high shear forces to form a latex-particle slurry. By means of the invention, over 60 wt-% of the latex can be adsorbed on the solids. Latex immobilization increases the surface strength of final coating layer and allows for a decrease of latex consumption in paper and cardboard and paint applications. | 05-13-2010 |
