    摘要： A hydraulic rod and tube extrusion press having a main extrusion ram and a piercer connected to a piston which works in a cylinder within the extrusion ram. In order to extrude tube around the piercer with the tip of the piercer stationary in the mouth of the die means are provided for supplying fluid to the return stroke chamber of the piercer piston cylinder so that the piercer is retracted at an appropriate rate relatively to the extrusion ram as the extrusion ram advances.

    摘要： A machine for bending concrete-reinforcing bars and the like is provided with automatic electric sequence control means for performing a desired sequence of bending operations of selected predetermined bending angles. The machine has slip rings of angular extents corresponding to the selectable angles and a contact drum cooperating with these. On the drum are a series of sets of pairs of selectable contacts; each set corresponds to one bending operation and the selected contact pair in the set cooperates with a corresponding slip ring to determine the bending angle for that operation. The drum is stepwise rotated to effect the sequence of operations. To compensate for elastic relaxation of the bar after bending, the bending may be continued beyond the predetermined angle by a further angle determined by measurement of energy absorption, or current consumption, or a time interval, for bending in the elastic range of the bar material. Means for effecting such compensation automatically are described.

    摘要翻译： 用于弯曲混凝土钢筋等的机器设置有用于执行所选择的预定弯曲角度的期望顺序的弯曲操作的自动电动顺序控制装置。 机器具有对应于可选角度的角度范围的滑环和与这些角度协作的接触鼓。 在鼓上是一系列可选择的接触对; 每个组对应于一个弯曲操作，并且该组中所选择的接触对与相应的滑环协作以确定该操作的弯曲角度。 滚筒逐步旋转以实现操作顺序。 为了补偿弯曲之后的棒的弹性松弛，弯曲可以通过测量能量吸收或电流消耗或时间间隔确定的另一角度继续超过预定角度，用于在棒材的弹性范围内弯曲 。 自动进行这种补偿的手段被描述。

    摘要： A high-speed hammer wherein the working tools secured, respectively, on the anvil block and crosshead of a frame perform a working stroke being acted upon by a power unit mounted on the frame, and are returned to the initial position by compressed gas contained in a space in the anvil block. Said space accommodates a piston whose rod is adjustably connected with a bed for adjusting the position of the frame relative to said bed.
