    • A ceramic arc tube assembly for an arc discharge lamp includes an arc tube having openings for electrode feedthroughs at opposite ends. The feedthroughs each comprise a niobium tube having a tungsten electrode welded to it. A connection wire is welded to the feedthrough at or near the end of the niobium tube, and the feedthrough is subsequently sealed into the arc tube with the connection wire abutting the arc tube. Since the connection wire is prewelded to the feedthrough, the feedthrough can be made as short as practicable without risk of damaging the seal during welding. As a result, feedthrough material cost is substantially reduced. Preferably, the connection wire is used for locating the feedthrough in the arc tube during seal formation.
    • 一种用于电弧放电灯的陶瓷电弧管组件包括在相对端具有用于电极馈通的开口的电弧管。 馈通每个包括具有焊接到其上的钨电极的铌管。 连接线焊接到铌管端部或其附近的馈通端,随后连接线与电弧管邻接,随后将馈通密封到电弧管中。 由于连接线预焊接到馈通,所以馈通可以尽可能短地实现,而不会在焊接期间损坏密封的风险。 因此,馈通材料成本显着降低。 优选地,连接线用于在密封形成期间将馈通定位在电弧管中。

    • In certain embodiments, a system includes a milking parlor entrance lane with an entrance positioned adjacent to a cattle holding pen and an exit positioned adjacent to one or more stalls of a rotary milking platform. The system also includes an exit lane positioned on a side of the entrance lane opposite a forward direction of rotation of the rotary milking platform, the milking parlor exit lane positioned adjacent to one or more stalls of a rotary milking platform such that dairy cows may enter the exit lane from the one or more stalls of the rotary milking platform after being milked. The system also includes a pressure sensor positioned adjacent to the exit lane, the pressure sensor operable to generate a trigger in response to detecting a triggering pressure on the pressure sensor. The pressure sensor is additionally operable to communicate the generated trigger to initiate the stopping of the rotary milking platform.
    • 在某些实施例中,系统包括挤奶厅入口通道,其中定位在牛保持笔附近的入口以及邻近旋转挤奶平台的一个或多个档位定位的出口。 该系统还包括位于入口车道侧面的出口车道,该出口车道与旋转挤奶平台的向前旋转方向相反,挤奶室出口车道邻近旋转挤奶平台的一个或多个档位定位,使得奶牛可以进入 在挤奶后来自旋转挤奶平台的一个或多个档位的出口车道。 该系统还包括邻近出口通道定位的压力传感器,压力传感器可操作以响应于检测压力传感器上的触发压力而产生触发器。 压力传感器另外可操作地通信所产生的触发器以启动旋转挤奶平台的停止。
