    • Apparatus for reducing the diameter, rounding or straightening of pipe or tubing by rolling comprising a plurality of cylindrical rollers arranged in a parallel-cylindrical array through which the pipe or tubing is passed, the rollers being skewed to displace their central contact zones radially inwards bringing them into forceful contact with the external surface of the pipe or tubing, and being rotated to cause the central contact zones to describe helical paths along the external surface of the pipe or tubing. Thereby to progressively apply locally to the whole of the external surface of the pipe or tubing a compressive force in excess of the yield strength of its material, causing the pipe or tubing to adopt a set at a smaller diameter.
    • 用于通过轧制减小管或管的直径,圆整或矫直的装置,包括以平行圆柱形阵列布置的多个圆柱形辊,管或管通过该圆柱形阵列,辊被歪斜以使其中心接触区径向向内移动,带来 它们与管或管的外表面有力地接触,并且被旋转以使得中心接触区描述沿管或管的外表面的螺旋路径。 从而逐渐地将管道或管道的整个外表面逐渐施加超过其材料的屈服强度的压缩力,导致管道或管道采用较小直径的组合。

    • A method of joining individual rigid members in railings, fencing, balustrading or the like in which the ends of secondary members of smaller diameter are inserted through suitable apertures provided in the walls of primary members of larger diameter into the interiors of the primary members, the interiors then being filled with a suitable foaming polymer material in pressurized liquid form, the foaming polymer material expanding to fill the interiors around the ends of the secondary members and catalyzing to form a solid and more or less rigid foam material with a strong and permanent adhesive attachment to all surfaces.
    • 将单个刚性构件连接在栏杆,围栏,栏杆等中的方法,其中较小直径的次要构件的端部通过设置在较大直径的主构件的壁中的合适的孔插入主构件的内部, 然后内部填充有加压液体形式的合适的发泡聚合物材料,发泡聚合物材料膨胀以填充第二构件的端部周围的内部并催化以形成具有坚固和永久粘合剂的固体和或多或少刚性的泡沫材料 附着于所有表面。
