摘要： A pipe punch apparatus which generally comprises a punch housing, a punch means situated within the punch housing, and a collar. The punch housing is connected to a bi-directional hydraulic fluid pump means. Depending on which direction the pump is set, the pump releases fluid into the punch housing which causes the punch means to either extend from the punch housing or retract into the punch housing. The collar is connected to the punch housing by a connecting means so that a notch within the collar receives the punch means when the punch means is in the extended position. The parts are also relatively situated so that positioning the punch housing within a pipe will cause the collar to be located exterior to the pipe. Thus, as the punch means moves from its initial retracted position to its extended position, it will also punch a hole through the pipe. Because the build up of hydraulic pressure which causes the punch means to move is gradual, no friction or heat, or only a negligible amount, is generated by the punching action. Functionally applying the pipe punch apparatus discloses a method for punching holes in pipes.

摘要翻译： 管冲头装置，其通常包括冲头外壳，位于冲头外壳内的冲头装置和套环。 冲压外壳连接到双向液压泵装置。 根据泵的设置方向，泵将流体释放到冲头外壳中，这导致冲头装置从冲头外壳延伸或缩回冲头外壳。 套环通过连接装置连接到冲头壳体，使得当冲头装置处于伸出位置时，套环内的凹口接收冲头装置。 这些部件也相对位置，使得将冲头外壳定位在管内将使套环位于管的外部。 因此，当冲头装置从其初始缩回位置移动到其伸出位置时，其也将穿过管穿孔。 因为引起冲压机构移动的液压的累积是逐渐的，所以通过冲压动作产生不产生摩擦力或热量，或仅可忽略的量。 功能性地施加管道冲压装置公开了一种在管道中冲孔的方法。

摘要： A level sensor offset mounting mechanism that mounts in the tank fill pipe of an underground fuel tank and provides an offset for the lower level sensor portion from the drop tube. The level sensor offset mounting mechanism connects to an inner wall of the tank fill pipe by a connector. A conduit extends vertically downward from the connector to a position below the top of the tank. At the lower end of the conduit, a selectively rotatable offset device provides a horizontal offset away from the drop tube. The offset device may be rotated to an insertion position, wherein no offset is provided, to facilitate insertion, or extraction, of the level sensor into the tank. Connected to the offset device at an end distal the connection to the upper portion, the lower portion of the level sensor measures the fuel and water levels within the tank. This lower portion generally includes an instrumentation housing, a lower conduit, a fuel level float, a water level float, and a magnetostrictive device for determining the positions of the floats. The level sensor offset device is designed such that electrical wiring may be passed therethrough without allowing fuel vapors to escape the tank.
