  • Patent number: 6156260
    Abstract: A chamber for receiving a downward flow of liquid metal includes a generally horizontal base having a generally planar impact surface. 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.

  • Patent number: 5683748
    Abstract: A process for inhibiting acidic corrosion in the crown of a concrete sewer pipeline of the type created by the generation of sulfuric acid within the pipeline and a lowering of the pH at the surface of the concrete. The process comprises the forming of a slurry of magnesium hydroxide, preferably precipitated from seawater, and water wherein the magnesium hydroxide comprises at least about 25-50% of the slurry by weight, and spraying the slurry onto and along the crown of the concrete pipeline to provide a slurry coating on the crown of the pipeline of about 0.2 inches in thickness so as to provide a relatively long lasting barrier of high pH and thereby prevent acidic corrosion of the pipeline.
