    摘要： A gated mold for casting concrete pipe requires no wedges or bolts for securement. A core mold may be contracted by lifting at an actuation point, and expanded by resting on a base ring. An external mold may be expanded by lifting at an actuation point, and contracted by resting on a base ring. The mold gates are opened and closed with sets of collapsing links pivotably attached to a longitudinally extending actuation column. Longitudinal motion of the actuation column forces the links to collapse or extend, thereby expanding or contracting the mold. Appropriately positioned actuation and lifting points are provided such that the mold can be lifted vertically along the longitudinal axis containing the mold center of gravity.

    摘要翻译： 用于铸造混凝土管的浇注模具不需要用于固定的楔形或螺栓。 芯模可以通过在致动点处提升而收缩，并且通过搁置在基环上而膨胀。 外部模具可以通过在致动点处提升而膨胀，并且通过搁置在基座上而收缩。 模具门被打开和关闭，具有可枢转地附接到纵向延伸的致动柱的塌缩连接件。 致动柱的纵向运动迫使连杆塌缩或延伸，从而使模具膨胀或收缩。 提供适当定位的致动和提升点，使得模具可以沿着包含模具重心的纵向轴线垂直地提升。

    摘要： Airfoils having a leading edge, a trailing edge, a first end, and a second end with a leading edge hybrid skin core cavity formed within the airfoil extending from the first end to the second end proximate the leading edge, the cavity having a hot wall and a cold wall. The cavity has a variable height-to-width ratio in a direction from the first end to the second end, with a first aspect ratio proximate the first end and a second aspect ratio proximate the second end with the height defined as a maximum distance between the hot wall and the cold wall and the width is defined as an arc length of the cold wall.

    摘要： Airfoil bodies having a first core cavity and a second core cavity located within the airfoil body and adjacent the first core cavity, wherein the second core cavity is defined by a first cavity wall, a second cavity wall, a first exterior wall, and a second exterior wall, wherein the first cavity wall is located between the first and second core cavities. The first cavity wall includes a first surface angled toward the first exterior wall and a second surface angled toward the second exterior wall. At least one first cavity impingement hole is formed within the first surface. At least one circuit exit is located in the first exterior wall, the at least one circuit exit arranged to expel air from the second core cavity through the first exterior wall.

    摘要： Centrifugal casting apparatus for casting cylinder liners and other tubular articles, characterized by recovery of at least a major portion of the particulate refractory material used to line the mold, with the recovered refractory material being suitable for re-use. The apparatus provides a chamber having aligned openings through which the cast article moves as the article is withdrawn from the mold by a puller. Particulate refractory material from within the mold and from the surface of the cast article is collected in the chamber and conveyed from the chamber to separator means for removal of debris.
