A first faceted sidewall having a plurality of facets formed therein, generally extends upwardly from and encompasses the planar surface to define an interior space. The interior space has an upper opening for receiving the downward flow of liquid metal. A second wall extends inwardly and upwardly from the first faceted wall toward the upper opening. A plurality of buttresses are spaced along the first faceted wall. Each of the buttresses extends between the impact surface and the second faceted wall. The buttresses form a plurality of discrete pockets including at least one facet. The pockets are defined by the buttresses, the impact surface, the first faceted wall and the second wall. The buttresses laterally deflect and divide the radial outward flow into a plurality of discrete flow patterns associated with the plurality of pockets. ## Claims ### Claim 1 A chamber for receiving a flow of liquid metal comprising; a base having a generally planar impact surface; a first wall coupled to a periphery of the planar surface and defining an interior space having an opening for receiving the flow of liquid metal; a second wall extending inwardly and upwardly from the first wall, the base, first wall and second wall defining a liquid metal stream reduction region; and a plurality of buttresses positioned within the liquid metal stream reduction region, each of the buttresses extending between the first wall, the impact surface and the second wall, the buttresses defining a plurality of discrete pockets within said liquid metal stream reduction region. ### Claim 2 (depends on 1) The chamber of claim 1, whereby the chamber is constructed and arranged so that when the flow of liquid metal impacts the impact surface, the flow is spread radially outwardly toward the buttresses, which laterally deflect and divide the radial outward flow into a plurality of discrete flow patterns associated with the plurality of pockets. ### Claim 3 (depends on 1) The chamber of claim 1, wherein the first wall has a plurality of facets. ### Claim 4 (depends on 2) The chamber of claim 2, wherein the discrete flow patterns are directed out of the interior space in an upwardly and outwardly direction away from the downward flow of liquid metal. ### Claim 5 (depends on 1) The chamber of claim 1, including a third wall defining the upper opening of the interior space, the third wall extending generally upwardly from the second wall. ### Claim 6 (depends on 1) The chamber of claim 1, wherein the first wall is outwardly and upwardly angled at an angle greater than about 90.degree. from the planar impact surface. ### Claim 7 (depends on 6) The chamber of claim 6, wherein the first wall is angled at an angle between about 90 and 120.degree. from the planar impact surface. ### Claim 8 (depends on 1) The chamber of claim 1, wherein the second wall extends from the first wall at an angle of about 45 to 135.degree.. ### Claim 9 (depends on 8) The chamber of claim 8, wherein the second wall extends from the first wall at an angle of about 90.degree.. ### Claim 10 (depends on 5) The chamber of claim 5, wherein the third wall extends from the second wall at an angle of about 45 to 150.degree.. ### Claim 11 (depends on 10) The chamber of claim 10, wherein the third wall extends from the second wall at an angle of about 125.degree.. ### Claim 12 (depends on 3) The chamber of claim 3, wherein the first wall includes 4-10 facets. ### Claim 13 (depends on 12) The chamber of claim 12, wherein the first wall includes eight facets. ### Claim 14 (depends on 1) The chamber of claim 1, wherein the interior space includes 4-10 pockets. ### Claim 15 (depends on 14) The chamber of claim 14, wherein the interior space includes eight pockets. ### Claim 16 (depends on 1) The chamber of claim 1, wherein the first wall includes 4-10 buttresses. ### Claim 17 (depends on 16) The chamber of claim 16, wherein the first wall includes eight buttresses. ### Claim 18 (depends on 13) The chamber of claim 13, wherein the first faceted wall includes about eight buttresses forming about eight discrete pockets, each of the pockets including at least one facet. ### Claim 19 A method for receiving, laterally dividing and redirecting a flow of liquid metal comprising; receiving a flow of liquid metal in a chamber having a base including a generally planar impact surface, and a first faceted wall coupled to a periphery of the planar impact surface to define an interior space having an opening; radially spreading the flow outwardly towards the first wall; laterally deflecting and dividing the radial outward flow into a plurality of discrete flow patterns; and directing the flow patterns towards the apices of the facets. ### Claim 20 (depends on 19) The method of claim 19, further comprising the step of redirecting the flow patterns out of the opening in a direction away from the incoming flow of liquid metal.
