Abstract: An apparatus for supplying water or other fluids from a stationary pipe to a moving pipe. The stationary supply conduit has a seam which can be opened and closed somewhat in the fashion of a zipper. An extractor is located inside the supply conduit and has a riser portion which protrudes through an opening in the seam. The extractor is moveable along the length of the supply conduit. Seam opening means create an aperture as the riser approaches while closing means are provided to refasten the seam after the riser has passed. Fluid seals isolate the seam opening from the fluid being carried. The extractor rides on spherical rollers and can include an evacuator tube which removes any water seeping through the seals.

Abstract: An overhead irrigation system and a method of controlling it whereby a main irrigation pipe, supported on towers, is moved laterally across a field. The towers at the extremities of the pipe are independently driven while the remaining towers move in response to misalignment between pipe segments caused by the motion of the outside towers. Proper overall direction of the system is maintained by a path sensor which detects deviation from the designated path and corrects it by slowing down the tower at the end toward which the correction is required, thereby causing the entire unit to pivot about a point on or beyond and in line with the end of the unit. Two-way misalignment sensors are capable of propagating a path correction signal along the entire length of the unit and in either direction. An engine, generator and pump are mounted in a sling support hung from the pipe.
