    Abstract: A method for joining nonmetallic pipes underground, with the pipes having mating pairs of bells and spigots, by fitting between mating spigots and bells dry bands of an open celled material (preferably reticulated polyurethane foam) having a dry hydratable cement (preferably portland cement) impregnated therein and engaging each of the bands between one of the bells and its mating spigot. On wetting of the bands, the cement hydrates thereby hardening.

    Abstract: Pipes having dense, watertight concrete walls are produced by vibrating a rotating mould suspended on a roller shaft as the mold is being filled, and continuing its rotation without vibration for a short time after the mold is filled. Vibration is attained by ridges or fingers which can be made effective, or not, to vibrate the mold as it is rotating. In one form, fingers on a roller shaft are slidable between ineffective positions and positions where they serially engage a smooth running surface on the mold. In other forms, a mold is movable from a position where it is supported by engagement of a ridged running surface on either the roller shaft or the mold with a cylindrical surface on the other to a position where the cylindrical surface on the mold runs on the roller shaft or on an auxiliary sleeve without vibration.

    Abstract translation: 具有密实的水密混凝土墙壁的管道是通过在模具被填充时振动悬挂在辊轴上的旋转模具而产生的，并且在模具填充之后短时间内继续旋转而不振动。 振动是通过脊或手指获得的，这些脊或手指可以有效地使模具在旋转时振动。 在一种形式中，辊轴上的指状物可在无效位置和与模具上的平滑运行表面串联接合的位置之间滑动。 在其它形式中，模具可以从其被支撑的位置移动，该位置通过辊轴或模具上的脊状运行表面与圆柱形表面之间的接合而被移动到模具上的圆柱形表面在其上运行的位置 滚轴或辅助套筒无振动。

    Abstract: A method for replacing an existing utility pole comprising a proximal section having a bottom end attached to the earth and a distal section having hardware mounted thereon. A principal object is to replace the existing utility pole without disturbing the hardware. A new pole section is attached to the earth. The distal section with the hardware intact thereon is severed from the proximal section. The distal section is then connected to project from the new pole section. The new pole section can have a length different from the proximal section, so that net distance of the hardware from the earth is changed. Preferably the new pole section is made of prestressed concrete and is hollow to accommodate a line therein between the distal section and the earth to provide positive grounding to the earth.

    Abstract: A method of protecting pipes with bell and spigot joints (having metal parts) from corrosion by fitting between the spigot and bell at least one dry band of open celled material (preferably reticulated polyurethane foam) having a particulate alkaline material (preferably Portland cement) impregnated therein and engaging the band between the bell and the spigot. On wetting of the band, the alkaline material is hydrated to protect the metal.
