摘要： An apparatus for cutting a pipe includes a housing with a central aperture for holding the pipe in a fixed position. A rotatable collar is mounted on the outer surface of the fixed housing, with a cutting head attached to the collar. The cutting head is configured to translate forward and backward such that the combination of the rotational movement of the collar and the translational movement of the cutting head is capable of performing complex cuts without ever moving the pipe. A number of different cutting tools (laser, plasma, etc.) may be attached to the cutting head, and a variety of different tasks may be performed including cutting completely through the entire pipe, inscribing on the pipe surface, forming through-holes along the pipe, and the like.

摘要： A clamping device is configured to ensure that a workpiece fixed between the jaws of the clamp is self centered by coupling the jaws to a pair of linkages that rotate through the same angle as the application of a first causes the jaws to translate in linear fashion across the surface of the device. In particular, the clamping device utilizes coupled linkage (e.g., a 180° bell crank), in combination with slots for retaining opposing jaws and maintaining only linear movement of the jaws, thus providing a fast and accurate self-centering arrangement. The clamping device may also be located within a hollow workpiece and controlled to move the jaws outward and engage the inner surface of the hollow workpiece in a self-aligned configuration.

摘要： A method of performing instantaneous protection in a trip unit is presented. The electronic trip unit includes a microcontroller and associated ROM having trip unit application code, e.g., main functionality firmware, including initializing parameters, and boot code, stored therein and EEPROM having operational parameter code stored therein. An instantaneous protection algorithm (program) stored in the memory of the trip unit has a `WAIT` state and a `RUN` state. In the RUN state samples of the sensed current that classify as points that are accumulated in a point register. Accumulation of a determined number of points qualifies as a peak. These peaks are accumulated in a peak register. If a point is not detected within a determined time period, then the count of peaks accumulated in the peak register is decremented, thereby provided a cooling function. When the count in the peak register exceeds the sensor limit a signal is generated by the microcontroller to initiate the trip.
摘要翻译：提出了一种在跳闸单元中执行瞬时保护的方法。电子跳闸单元包括微控制器和相关联的ROM，其具有跳闸单元应用代码，例如主存功能固件，包括其中存储的初始化参数和引导代码以及存储有操作参数代码的EEPROM。存储在跳闸单元的存储器中的瞬时保护算法（程序）具有“等待”状态和“运行”状态。在RUN状态下，感应电流的样本被分类为积分在点寄存器中的点。确定数量积分的积分符合高峰。这些峰值累积在峰值寄存器中。如果在确定的时间段内没有检测到点，则峰值寄存器中累积的峰值的计数减少，从而提供冷却功能。当峰值寄存器中的计数超过传感器限制时，微控制器产生信号以启动跳闸。
