    摘要： A gasket for preventing separation of interconnected pipes without damaging the pipes. The gasket includes a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes a row of exposed teeth configured for engaging a spigot end of a pipe and a trough configured for pivotably engaging a bead on a bell. The trough is further configured for shearing or deforming the bead and inhibiting over-pivoting of the segment about the bead when the pipes are partially withdrawn away from one another, for example, during over-pressurization of the pipes.

    摘要： A metal utility pole including a hollow, centrifugally cast, ductile iron utility pole member having a tapered exterior and variable wall thickness for providing a shortened press-fit, slip joint between interconnected pole members. The shortened joint length requires less metal than conventional press-fit, slip joints while maintaining or improving the overall strength of the joint. This is accomplished by increasing the wall thickness of one or both interconnected pole members along the joint relative to the wall thickness of the body or mid-section of the pole members.

    摘要翻译： 一种金属电线杆，包括具有锥形外部和可变壁厚的中空的离心铸造的球墨铸铁电线杆部件，用于在互连的极部件之间提供缩短的压配合滑动接头。 缩短的接头长度比常规压配，滑动接头的金属要少，同时保持或提高接头的整体强度。 这是通过相对于杆件的主体或中间部分的壁厚增加沿着接头的一个或两个互连的极构件的壁厚来实现的。

    摘要： A utility pole mold including an elongated, hollow mold body having an internally tapered end and a reservoir extending radially out therefrom. A reusable barrier member is detachably secured to the at least one wall opposite the tapered end for containing a molten metal within the reservoir. In use, a lance is inserted into the mold body and a pouring end of the lance is positioned about the reservoir. The mold body and reservoir are then rotated, and the molten metal is poured from the pouring end at a constant rate. As the lance travels along the length of the mold body at an accelerating rate, a continuous layer of the molten material is deposited within the mold body and the reservoir. Following casting, the barrier is removed from the reservoir, and the newly formed utility pole is removed from mold. That portion of the pole that was formed within the reservoir portion is then removed to provide a pole having a bottom end with a desired wall thickness and interior taper.
