    • A continuous, non-metallic conduit for conductors, such as electrical wiring and/or fiber optic cable. The continuous conduit being formed from at least one pair of first and second conduits having enlarged ends coupled together. The enlarged ends are belled or otherwise have a diameter greater than that of the straight run (non-belled) portions of the conduit. The enlarged ends of the conduit being coupled together by fusion or welding, and an internal bead or ridge being formed by the coupling process. The enlarged ends are dimensioned such that the internal bead or ridge formed at the junction between the two enlarged ends does not project radially inward to a position equal to or less than the diameter of the straight run portion of the conduits. The continuous conduit is configured to allow the conductor to be passed therethrough such that the conductor does not contact the internal bead or ridge.
    • 用于导体的连续的非金属导管,例如电线和/或光纤电缆。 连续管道由至少一对第一和第二管道形成,第一和第二管道具有扩大的端部联接在一起。 扩大的端部被鼓起或者具有比导管的直线(非鼓形)部分的直径大的直径。 通过熔接或焊接将导管的扩大端连接在一起,以及通过耦合过程形成的内部珠或脊。 扩大的端部的尺寸使得形成在两个扩大端部之间的接合部处的内部胎圈或脊部不径向向内突出到等于或小于导管的直线部分的直径的位置。 连续管道被配置为允许导体通过,使得导体不接触内部珠缘或脊。

    • A nozzle (410) for guiding molten metal comprises an inlet (106) at an upstream first end and at least one outlet (210) towards a downstream second end. An inner surface (117) is provided between the inlet (106) and the at least one outlet (210) to define a bore (118) through the nozzle (410). The bore (118) has a throat region (200) adjacent the inlet (106). An annular channel (420) is provided in the inner surface of the nozzle (410). A fluid supply means (900) is arranged to introduce fluid into the bore (118) via the annular channel (420) or downstream thereof. The throat region (200) has a convexly curved surface and the annular channel (420) is located within or adjacent the throat region (200). The invention also provides for a method of controlling the flow of molten metal through a nozzle (410), as described above, and a system for controlling the flow of molten metal. The system comprises a nozzle (410), as described above, and a stopper rod (100) configured to be received in the throat region (200) of the nozzle (410) to control the flow of molten metal through the nozzle (410).
