| Number | Title | Issue Date |
| 7449045 | Method of handling liquid non-ferrous metals with refractory material A method of handling liquid non-ferrous metals after smelting. The liquid metal is in contact with a solid refractory material, and in the absence of electrical currents passing through the liquid-metal-contacting surfaces. The solid material is Ti3SiC | 11/11/2008 |
| 6926066 | Magnesium die casting system An improved magnesium die casting system incorporates filling of the shot sleeve from the underside and/or in-line re-melting of scrap magnesium using a re-melt furnace. A pump is used to transfer molten magnesium from a casting furnace to the shot sleeve through an... | 08/09/2005 |
| 5914440 | Method and apparatus removal of solid particles from magnesium chloride electrolyte and molten magnesium by filtration The present invention is concerned with a system for the filtration of molten material. The system is particularly useful for removing MgO impurities present in molten magnesium chloride electrolyte. The invention also comprises a method for removing soli... | 06/22/1999 |
| 5169542 | Filters for light metals Filters for filtering molten light metals comprise a reticular foam having a composition comprising graphite, wollastonite, silica and an alkali phosphate glass. The filters have a low hardness and can readily be machined accurately from large pieces of t... | 12/08/1992 |
| 4572818 | Process for purifying metal compositions Purified metal compositions and metal compositions free of secondary phase material are produced by heating a metal alloy from the nonequilibrium solidus temperature while subjecting the liquid-solid mixture to high pressure and forcing the liquid through... | 02/25/1986 |
| 4457496 | Filtration block for liquid metals and alloys, with a mechanical and physical-chemical effect The invention concerns a filtration block for liquid alloys and metals, with a mechanical and physical-chemical effect. Agglomerating, for example by sintering, elements of an active mineral compound based on fluorides, results in a porous structure with a hig... | 07/03/1984 |
| 4379718 | Process for separating solid particulates from a melt A process for treating a metal recovery byproduct which contains solid ash constituents entrained in a melt comprising a major amount of a molten salt and a minor amount of molten metal in which the melt is filtered through a high-temperature filter appar... | 04/12/1983 |
