    • A wave threaded fastener and system. A wave thread extends from the outer surface of the body and is made up of a profile wave and a lateral wave. The profile wave includes a plurality of profile crests and profile roots defining a plurality of profile thread widths. The lateral wave includes at least one lateral crest and at least one lateral root defining at least one wave period. Each wave period forms a period arc having a period arc angle and the sum of all period arc angles about the lateral wave equals three hundred and sixty degrees. Each of the profile crests and roots are aligned with corresponding lateral crests and roots and the wave thread travels one profile thread width per each period arc traveled.
    • 波纹螺纹紧固件和系统。 波纹从主体的外表面延伸并且由轮廓波和横波构成。 轮廓波包括多个轮廓峰和限定多个轮廓螺纹宽度的轮廓根。 横波包括至少一个横向波峰和限定至少一个波周期的至少一个侧根。 每个波周期形成具有周期弧角的周期弧,并且围绕横波的所有周期弧角的和等于三百六十度。 每个轮廓峰和根与对应的横向顶部和根部对准,并且波纹沿每个周期的弧线行进一个轮廓螺纹宽度。

    • A system for detecting and locating a leak through a membrane that includes a detector array and computer. The detector array includes a boundary wire loop, sensors, and leads. The boundary wire loop surrounds the area to be tested and generates electrical tension on the surface of the membrane. The sensors are laid out in a sensor array and are placed on top of a membrane and within the boundary wire loop. The sensors are encased in a plastic covered cable or individual wires which have open ends for their terminations forming a cable so that the sensors made by the open terminations form a chain. Each sensor communicates individually with the computer and the signals from the sensors are used by the computer to perform vector mapping that detects and locates leaks through the membrane.
    • 一种用于检测和定位通过包括检测器阵列和计算机的膜的泄漏的系统。 检测器阵列包括边界线环,传感器和引线。 边界线环绕着要测试的区域,并在膜的表面产生电张力。 传感器布置在传感器阵列中,并放置在膜的顶部和边界线环内。 传感器被封装在塑料覆盖的电缆或单独的电线中,其具有形成电缆的端接的开口端,使得由开放式终端制成的传感器形成链条。 每个传感器与计算机单独通信,计算机使用来自传感器的信号执行矢量映射,以检测和定位通过膜的泄漏。
