    • A gas-operated integrated punching device with plate presser, including: a tubular containment body closed hermetically by a bottom and by a head that is perforated for the passage of a piston-operated plate presser moving within the tubular body; the plate presser being crossed coaxially by a punch connected to the tubular body; a compression and expansion chamber for loading pressurized gas being formed between the plate presser and the bottom such that the pressurized gas pushes the plate presser between a first fully extracted configuration with the outer end of the plate presser not in contact with a metal plate to be woked and protruding from the head by such a length as to affect the tip of the punch, and a second configuration at least partly retracted into the tubular body with the outer end of the plate presser in contact with a metal plate being worked.
    • 一种带压板机的气动一体式冲压装置,包括:一个由底部气密封闭的管状容纳体,以及一个穿孔的头部,用于通过在管状体内移动的活塞式压板; 压板机通过连接到管状体的冲头同轴地交叉; 用于加载加压气体的压缩和膨胀室,其形成在压板机和底部之间,使得加压气体在第一完全抽出构型之间推动压板机与压板机的外端不与金属板接触, 从头部起动和突出一定长度以影响冲头的尖端,并且第二构造至少部分地缩回到管状体中,压板的外端与正在加工的金属板接触。

    • A method for secure identification of stations connected over data communications networks during a transaction, comprising transmitting, on the part of a first station to a second station, an identification index of a reference cell in a sequence of codes known to both stations and a first code in the sequence and chosen according to a first criterion known to both stations; identifying, by the second station, a cell in the sequence through the received index; verifying the first code by the second station; transmitting, by the second station toward the first station, a second code, in the series of codes calculated according to a second criterion known to both stations; verifying by the first station, the correctness of the second code; marking, by the first station and preferably also by the second station, the indices related to the codes that have been used as unusable for subsequent transactions.
    • 一种用于安全识别在事务期间通过数据通信网络连接的站的方法,包括在第一站的一部分向第二站发送以两个站已知的代码序列的参考小区的标识索引,以及第一 代码,并根据两个站点已知的第一个标准进行选择; 由所述第二站识别通过所述接收到的索引的所述序列中的小区; 验证第二站的第一个代码; 由所述第二站朝向所述第一站发送根据两个站已知的第二标准计算的一系列代码中的第二代码; 由第一站验证第二代码的正确性; 由第一站并且优选地由第二站标记与已被用于后续交易的代码相关的指数。
