20090159231 | Molten Metal Pressure Pour Furnace - An apparatus and process are provided for discharging a dose of a molten metal from a pressure pour furnace. A heating chamber of the furnace is used to keep the molten metal at a selected temperature. A sealing port between the heating chamber and a pressure chamber allows selectively filling of the pressure chamber with molten metal from the heating chamber by inserting or removing a sealing means from the sealing port. The sealing means inserted in the sealing port also provides a means for preventing back flow of the molten metal to the heating chamber when the pressure chamber is pressurized. Differential pressure sensing of the pressure of the molten metal in the pressure chamber and the pressure of the pressurizing gas in the pressure chamber can optionally be used to achieve an accurate measured discharge from the pressure chamber as the level of molten metal decreases from repeated discharges of doses from the furnace. The sealing plate in which the sealing port is disposed and the sealing means selectively inserted or removed from the sealing port can be used as a metering valve between two molten metal containing components such as a launder and a pressure chamber of a pressure pour furnace. | 06-25-2009 |

20130306262 | Blow Molding of Bulk Metallic Glass - A very low pressure gas or blow forming process for shaping a bulk metallic glass (BMG) in its supercooled liquid state that avoids the frictional stick forces experienced by conventional shaping techniques by engineering the expansion of a pre-shape or parison of BMG material such that substantially all of the lateral strain required to form the final article is accomplished prior to the outer surface of the parison contacting the surface of the shaping apparatus is provided. The capability offered by the inventive shaping process to avoid the frictional forces exerted by the shaping apparatus surface allows for the formation of precision net-shape complex multi-scale parts and components using processing conditions inaccessible by conventional processes. | 11-21-2013 |
