Abstract
A pressure lock system passes a wire along a wire path from a wire source at a high pressure first region to a destination at a low pressure second region. The pressure lock system includes a pressure lock chamber. A first conduit has an interior positioned to pass the wire along the path and is mounted for rotation. A second conduit has an interior positioned to pass the wire from the pressure lock chamber and is also mounted for rotation. A motor may drive rotation of the first conduit and the second conduit. Pumps may maintain a pressure of the pressure lock chamber lower than a pressure of the first region.
