    • A personal welding enclosure has a rigid support frame and a tent-like enclosure defining an inner work chamber. The enclosure, which is supported by the rigid frame, is beneficially formed from impermeable, flame-proof and/or flame-resistant fabric having desired strength, durability and thermal insulation characteristics. A pneumatic automatic shut off control system monitors variables in and around the enclosure, alerts personnel to the existence of potentially unsafe conditions within the enclosure and automatically terminates welding and/or other hot-work when an unsafe condition is detected.
    • 个人焊接外壳具有刚性支撑框架和限定内部工作室的帐篷状外壳。 由刚性框架支撑的外壳有利地由具有期望的强度,耐久性和绝热特性的不可渗透的防火和/或阻燃织物形成。 气动自动关闭控制系统监控机箱内部和周围的变化,警告人员在机箱内存在潜在的不安全状态,并在检测到不安全状态时自动终止焊接和/或其他热作业。

    • Apparatus for protecting a device from transients. The apparatus includes a switching network and a transmission line electrically connecting an input to an output. The switching network includes a stub connected near the input with a detector at the other end, a switch, and a communication path therebetween. The detector detects a transient and communicates with the switch. The switch then actuates to place a low impendence across the output of the transmission line, thereby attenuating the transient. The switching network has a switching time that equals the sum of the times to detect the transient at the input, transmit a signal corresponding to the detection to the switch, and actuate the switch. The input signal travels from the input to the output along the transmission line, which has a propagation delay. The propagation delay is greater than the stub propagation time plus the switching time of the switch network.
    • 用于保护设备免于瞬变的设备。 该装置包括交换网络和将输入电连接到输出端的传输线。 交换网络包括在输入端附近连接有在另一端具有检测器的短截线,开关以及它们之间的通信路径。 检测器检测到瞬态并与开关通信。 然后开关致动以在传输线的输出端施加低阻抗,从而衰减瞬变。 开关网络具有等于检测输入端的瞬态的时间之和的开关时间,将与检测相对应的信号发送到开关,并且启动开关。 输入信号沿着传输线从输入传输到输出,传输线具有传播延迟。 传播延迟大于存根传播时间加开关网络的切换时间。
