    • A weld monitor system measures and records physical conditions under which welds are made between parts weld fused by an automated welding machine. Analog data of pressure in hydraulic circuits of hydraulically driven operations of an automatic welding machine, and analog data of weld current amperages applied to welding electrodes of the welding machine is acquired and stored by the weld monitor system to provide an archival record of the physical conditions of the formation of all welds made by the automatic welding machine. The weld monitor system compares the data to a predetermined range of values and sends a control signal to a welding machine controller indicative of the results of the data comparisons. An automatic part identification unit of the weld monitor system sequentially applies permanent unique indicia to parts weld assembled so that weld assembly data for uniquely identified parts can be readily retrieved from the stored data. Welding condition data acquired by the weld monitor system provides a broad range source of production process data on which to perform statistical process control analysis.
    • 焊接监控系统测量和记录在自动焊接机熔接的焊接部分之间进行焊接的物理条件。 自动焊接机的液压驱动操作的液压回路中的压力模拟数据以及焊接机焊接电极的焊接电流安培数的模拟数据由焊接监控系统获取并存储,以提供物理条件的档案记录 形成由自动焊接机制造的所有焊缝。 焊接监视器系统将数据与预定值的范围进行比较,并将控制信号发送给指示数据比较结果的焊接机控制器。 焊接监视器系统的自动部件识别单元对组装的部件焊接顺序地施加永久性唯一标记,使得可以容易地从存储的数据中检索唯一识别部件的焊接组装数据。 由焊接监测系统获得的焊接条件数据提供了广泛的生产过程数据源,用于执行统计过程控制分析。

    • A plug-type alarm switch for supervision of handwheel water valves and the like has an enclosure having a key-locked cover and containing, wired in series, a two-connector female receptacle and a normally closed enclosure cover tamper switch. The receptacle, otherwise movable within the enclosure, is held in place on being mated through a passage in the enclosure wall to a two-prong male plug, which is shorted by an insulated loop of wire passed through the handwheel. If the handwheel is turned, pulling the loop, the plug and receptacle are unmated, opening the switch circuit and signalling an alarm. The unmated receptacle will not remain aligned with the passage for reinsertion of the plug prongs; to restore the circuit the cover must be unlocked and removed and the receptacle must be physically held in proper alignment as the plug is reinserted.BACKGROUND OF THE INVENTION
    • 用于监控手轮水阀等的插头式报警开关具有一个具有钥匙锁盖的外壳,并且包含串联的两个连接器的母插座和一个常闭的外壳盖篡改开关。 另外,可以在外壳内移动的插座通过外壳壁中的通道配合而保持在适当的位置,并通过一根通过手轮的绝缘线路短路的双头插头。 如果手轮转动,拉动回路,插头和插座不配合,打开开关电路并发出报警。 未配合的容器不会保持与通道对齐以重新插入插头插头; 为了恢复电路,必须将盖子解锁和拆卸,并且当插头重新插入时,插座必须物理上保持正确对齐。
