20100276528 | APPARATUS FOR RECLAMATION OF MOLDING SAND - The object of the invention is to provide an apparatus for reclamation of molding sand by which the quality of the reclaimed molding sand is enhanced. The apparatus for reclamation of molding sand comprises a part for feeding the molding sand | 11-04-2010 |
20100307707 | CASTING METHOD TO PRODUCE A CASTING AND PRESS USED FOR THE CASTING METHOD - This invention provides a casting method for a casting of high quality and a press for casting such a casting by controlling the speed of the press that presses a mold in the pressing process, after a upper mold overlaps a lower mold. The invention provides a casting method for a casting and the press for that casting method. They use the lower mold having a concave portion that has a shape of a casting, and the upper mold having a convex portion that has a shape of the casting, which convex portion forms a cavity to produce the casting by overlapping the lower mold. A casting method to produce a casting and a press used for the casting method, using a mold which forms a cavity in a shape of a casting, so as to produce a casting by overlapping a lower mold with an upper mold, which molds are molded by a molding method, said casting method comprises steps of: pouring into the lower mold a quantity of molten metal required to produce a casting; lowering the upper mold at a predetermined first speed until the upper mold reaches a predetermined position just before the upper mold starts contacting a surface of the molten metal; lowering the upper mold at a predetermined second speed after the upper mold is further lowered beyond the predetermined position; detecting and obtaining information on the status of the upper mold which overlaps the lower mold; and, stopping the lowering of the upper mold when detecting the information on the status of the upper mold that shows that the predetermined conditions are met. | 12-09-2010 |

20100018664 | CASTING PROCESS, UPPER MOLD ASSEMBLY AND METHOD OF SECURING CORE TO UPPER MOLD - Disclosed is a casting process with use of a lower mold | 01-28-2010 |
20130186970 | SHEARING DISPERSER, CIRCULATION-TYPE DISPERSING SYSTEM, AND CIRCULATION-TYPE DISPERSING METHOD - The present invention provides a disperser that gives a local dispersing effect and a homogenous dispersing effect and that achieves a more efficient dispersion. The shearing disperser comprising a rotor and an opposing member that is opposite the rotor, wherein the disperser disperses a slurry or liquid mixture by allowing the mixture to pass through the disperser and outwardly between the rotor and the opposing member by centrifugal force, and wherein the disperser further comprises a plurality of gaps that are provided between the rotor and the opposing member and lead the mixture outwardly; and a buffering space that is provided to connect an outermost gap to a gap located in a position inward from the outermost gap and that retains the mixture. | 07-25-2013 |
20130194888 | SYSTEM AND A METHOD FOR DISPERSING BY CIRCULATION - A system and a method for dispersing by circulating a mixture that simplifies the structure of the part for sealing a shaft of a dispersing device and lengthens the life of the device are provided. The system for dispersing by circulating a slurry or liquid mixture to disperse substances in the mixture comprises a rotating and continuously dispersing device that disperses the mixture, a tank that is connected to an outlet of the dispersing device, a circulating pump that circulates the mixture, and a piping that in series connects the dispersing device, the tank, and the circulating pump. In the dispersing device the outflow of the mixture is greater than the inflow so that an amount of the mixture in the dispersing device is maintained at a level where a part for sealing a shaft that is provided inside the dispersing device is not immersed. | 08-01-2013 |
20130315030 | TANK APPARATUS, A SYSTEM FOR DISPERSING BY CIRCULATING A MIXTURE, AND A METHOD FOR DISPERSING BY CIRCULATING A MIXTURE - A tank apparatus and a system for dispersing by circulating a mixture that prevents powdery additives from adhering to an inner face of a tank from scattering in the tank, from drifting on the surface of a liquid, and from agglutinating, are presented. The tank apparatus that stores a raw material that is slurry or liquid and supplies powdery additives to the raw material to mix them with the raw material comprises a tank for storing the raw material and a screw-type device for supplying powdery additives that is integral with the tank and supplies the powdery additives to the raw material in the tank, wherein a tip of a part for supplying powdery additives of the screw-type device for supplying powdery additives is inserted into the mixture in the tank. | 11-28-2013 |

20090321612 | MOLD - This invention provides a mold that can prevent molten metal from leaking out of it as well as from leaking onto a parting plane. The mold according to this invention comprises: a lower mold comprising a concave portion, having the shape of a product, into which the amount of molten metal required to produce a casting is poured; and an upper mold comprising a convex portion having the shape of a casting, and forming a cavity that molds a casting, when the upper mold overlaps the lower mold; and wherein a structure is formed so as to have certain clearances between the lower mold and the upper mold such that the molten metal is prevented from leaking onto the parting plane that is formed where the upper mold and the lower mold overlap, when the casting is produced. | 12-31-2009 |
