    Abstract: An alloy part is cast in a mold (280) having a part forming cavity (292, 294, 296). The method comprises pouring a first alloy into the mold. The pouring causes: a surface (550) of the first alloy in the part forming cavity to raise relative to the part forming cavity; a branch flow of the poured first alloy to pass upwardly through a first portion (304) of a passageway; and the branch flow to pass downwardly through a second portion (310), of the passageway; solidifying some of the first alloy in the passageway to block the passageway while at least some of the first alloy in the part forming cavity remains molten. A second alloy is poured into the mold atop the first alloy and solidified.

    Abstract translation: 合金部件铸造在具有部分形成腔体（292,294,296）的模具（280）中。 该方法包括将第一合金倒入模具中。 浇注原因：部件形成腔中的第一合金的表面（550）相对于部件形成腔体升高; 倾倒的第一合金的分支流向上通过通道的第一部分（304）; 并且所述分支流向下通过所述通道的第二部分（310）; 固化通道中的一些第一合金以阻挡通道，同时部件形成空腔中的至少一些第一合金保持熔融。 将第二合金倒入第一合金顶部的模具中并固化。

    Abstract: An alloy part is cast in a mold (280) having a part-forming cavity (292, 294, 296). The method comprises pouring a first alloy into the mold. The pouring causes: a surface (550) of the first alloy in the part-forming cavity to raise relative to the part-forming cavity; a branch flow of the poured first alloy to pass upwardly through a first portion (304) of a passageway; and the branch flow to pass downwardly through a second portion (310), of the passageway; solidifying some of the first alloy in the passageway to block the passageway while at least some of the first alloy in the part-forming cavity remains molten. A second alloy is poured into the mold atop the first alloy and solidified.

    Abstract: A pattern with internal cores for creating a hollow component is composed of a first pattern half having one or more first self- locating features; a second pattern half having one or more second self-locating features; and one or more cores disposed in contact with the one or more first self- locating features and the one or more second self-locating features. The method for its manufacture includes the steps of creating a first pattern half having one or more first self-locating features; creating a second pattern half having one or more second self- locating features; providing one or more cores; and assembling the pattern by engaging the one or more first self-locating features and the one or more second self- locating features about the one or more cores.
