    • A pipe coupling flange (16) comprising a central bore and having first and second ports for receiving valves and a plurality of channels, wherein a take-off channel links the first port with the central bore, a feed channel links the first port directly or indirectly with the second port; and wherein the second port links directly or indirectly with the exterior of the flange. Across two pipe flanges (16), and fixed directly to the periphery of each flange there may be a Bridge (30). The bridge (30) may be capable of having process media (24) monitoring devices fixed directly to it.
    • 一种管接头法兰(16),其包括中心孔并具有用于接收阀和多个通道的第一和第二端口,其中,引出通道将第一端口与中心孔连接,进料通道将第一端口直接或 间接与第二个港口; 并且其中所述第二端口直接或间接地连接到所述凸缘的外部。 横跨两个管道法兰(16),并直接固定在每个法兰的周边,可能有一个桥(30)。 桥(30)可能能够具有处理介质(24)直接固定在其上的监控装置。

    • A light emitting diode (LED) circuit having a plurality of LEDs electrically connected in series with a zener diode electrically connected to each LED in parallel. If an LED were to fail, the current can be routed around the failed LED, through the zener diode, and continue through the rest of the LEDs in the series connection. Thus, a failure in one LED does not cause the entire series string to lose their illumination. Some embodiments may place several LED strings in parallel with one another. Exemplary embodiments may mount the LCDs on a metal core printed circuit board (PCB). Further embodiments may place a thin metallic sheet or metallic surface on the rear surface of the PCB and in thermal communication with the PCB and/or LEDs.
    • 一种发光二极管(LED)电路,其具有与并联电连接到每个LED的齐纳二极管串联电连接的多个LED。 如果LED发生故障,则可以通过齐纳二极管将电流绕过故障LED,并通过串联连接中的其余LED继续。 因此,一个LED的故障不会导致整个串联串失去照明。 一些实施例可以将多个LED串彼此平行放置。 示例性实施例可将LCD安装在金属芯印刷电路板(PCB)上。 另外的实施例可以将薄金属片或金属表面放置在PCB的后表面上并与PCB和/或LED热连通。
