Assignee:

Alcoa Inc. - Pittsburgh PA

International Classification:

B22D 1704

US Classification:

164312, 164337, 164134

Abstract:

The filtering molten metal injector system includes a holder furnace, a casting mold supported above the holder furnace, and at least one molten metal injector supported from a bottom side of the casting mold. The holder furnace contains a supply of molten metal. The mold defines a mold cavity for receiving the molten metal from the holder furnace. The molten metal injector projects into the holder furnace. The molten metal injector includes a cylinder defining a piston cavity housing a reciprocating piston for pumping the molten metal upward from the holder furnace to the mold cavity. The cylinder and piston are at least partially submerged in the molten metal when the holder furnace contains the molten metal. The cylinder or the piston includes a molten metal intake for receiving the molten metal into the piston cavity when the holder furnace contains molten metal. A conduit connects the piston cavity to the mold cavity.

International Classification:

B22D017/04

US Classification:

164/316000

Abstract:

The injector includes a cylinder defining a piston cavity housing a reciprocating piston for pumping molten metal from a holder furnace and injecting the molten metal into the mold cavity of a casting mold. The piston defines a molten metal intake for receiving molten metal into the piston cavity. A check valve is positioned in the molten metal intake defmed by the piston. The check valve is preferably a ball check valve. The cylinder further defines a fill conduit in fluid communication with the piston cavity. The fill conduit extends through a top wall of the cylinder and extends along an axis substantially parallel to the piston.

Inventors:

Thomas Meyer - Cleveland OH, US

International Classification:

F03D 9/00

US Classification:

290 55

Abstract:

A wind turbine having two blades is rotated by omnidirectional gas motion. A generator is connected by a shaft to the wind turbine for generating electrical power by the rotation of the wind turbine. A method of extracting energy from moving gas comprises rotating a wind turbine having two blades by omnidirectional gas motion. The method includes connecting a generator by a shaft to the wind turbine and generating electrical power by the rotation of the wind turbine.

International Classification:

US Classification:

75 10R

Abstract:

An apparatus and process for the reduction in a plasma stream of a feed material including a comminuted metal oxide, a slag former and a reductant utilizing an enclosed horizontal reactor having a reduction chamber and a filter chamber therein separated by an either common partition having a plurality of holes therethrough or a refractory lined passageway. Coke filter media in the filter chamber act to filter out entrained molten metal contained in the plasma stream with the partition or passageway preventing entry of the coke from the filter chamber into the metal bath contained in the reduction chamber thereby limiting the amount of carbon entering the metal produced. Unreduced metal oxide is provided in the slag layer of the metal bath to maintain the stoichiometric ratio between the metal and reductant in the reduction chamber. In alternate embodiments of the invention, the reactor is provided with a sloped floor or with a rocker mechanism to control the residence time of the metal with the coke thus limiting the amount of carbon entering the metal product. The exhausted plasma stream can be recycled for preheating and prereducing the incoming feed material.
