  • Patent number: 11940067
    Abstract: A system for remotely opening and closing a process equipment bolt flange joint may include a hydraulic cylinder actuator assembly for attaching to the flanges of a bolt flange joint to open and close the joint by operation of a remote hydraulic pump. More than one actuator assembly may be evenly spaced around the flange joint, to ensure even distribution of force around the joint. The system may have an accumulator for receiving hydraulic fluid expelled from the hydraulic cylinder during extension and to force hydraulic fluid back into the cylinder to close the flange joint upon pressure release at the pump. A drop trigger may be used to release hydraulic pressure at the pump for emergencies. The system may include a video camera for viewing the joint on a display. The components may be stored and transported on a mobile cart. A method of use is also disclosed.

  • Patent number: 5759007
    Abstract: The invention provides a manually operated machine for radially aligning one or more semiconductor wafers. The machine includes an elongated first "notch" roller for rotatably engaging the edge of the wafers, a gear train, and a hand crank for manually rotating the first roller in cooperation with the gear train. The wafers are aligned according to the notches as the wafers are engaged and rotated by the notch roller until the notch in each wafer falls over and is disengaged by that roller. The manual notch finder may also include an elongated second "position" roller for rotatably engaging the edge of the wafers. The position roller is disposed laterally near the notch roller and sized and shaped to engage the edge of the wafers fully along the periphery of each wafer so that the aligned wafers can be positioned to any degree of radial orientation. The invention also provides a combination notch or flat finder machine integrated with a wafer transfer machine.
