摘要: The invention provides media for absorption of phosphate and metal contaminants from a hydrocarbon stream and a method of making such media. The media comprise alumina with relatively minor amounts of calcia and magnesia and are made by a process in which the minor components or precursors of such components are dispersed in a gelled sol of a hydrated alumina such as boehmite.

摘要: A center pivot sprinkler system includes a sprinkler arm to be mounted at a pivot point at a first end of the sprinkler arm, the sprinkler arm defining a water conduit. A motive source can move the sprinkler arm in a circular motion about the pivot point. An end nozzle is supported at a second end of the sprinkler arm, and in fluid communication with the water conduit. A control valve is positioned between the water conduit and the end nozzle, and a control valve positioner can position the control valve. A position determining device determines the position of the end nozzle in a circular arc about the pivot point. A processor polls the position determining device to determine a then-current position of the end nozzle and determines a flow of water to be issued from the end nozzle as a function of the then-current position of the end nozzle.

摘要: A sprinkler which is controllable to provide water to an area to be sprinkled includes a sprinkler head to move between a first position and a second position. The sprinkler further includes a sprinkler head positioner to move the sprinkler head between the first and second positions, a sprinkler head position determiner to determine a current sprinkler head position between the first and second positions, a flow control valve to control flow of water from a water supply to the sprinkler head, a flow control valve positioner to establish a current control valve position for the flow control valve between an essentially fully closed control valve position and an essentially fully open control valve position, and a controller to receive a sprinkler head position signal from the sprinkler head position determiner and send a control valve control signal to the flow control valve positioner in response thereto.
