Abstract: A low capital investment system for irrigating a relatively large area field, comprising a mobile base, and a sprinkler mounted on the base and adapted to accumulate water from a water supply and to intermittently discharge accumulated water in an irrigating stream over the field. Apparatus is provided for propelling the base in a back and forth movement traversing a field, and for generally reversing the water discharge direction each time the direction of travel is reversed.The sprinkler includes a novel, resiliently expandable reservoir construction for accumulating relatively large volume, intermittent bursts, and a drive system which also provides relatively short range, continual irrigation. Separate sprinkler units can be used on a field concurrently, or a single unit can be moved over successive areas of a field until the whole field has been covered. The system may also be combined with a center pivot device to irrigate land that would otherwise be unused.

Abstract: An accumulator-distributor for gathering a quantity of water under pressure and rapidly discharging the quantity of water in bursts whereby large agricultural areas can be watered from a low volume source of irrigation water is shown. An expandible chamber is provided having a flexible diaphragm as one wall thereof. Bias means carried by the flexible diaphragm are adapted to exert a pressure upon the valve member closing the outlet opening from the chamber an amount insufficient to retract the valve member against the differential pressure of the accumulated water acting on the valve member. A second member is adapted to contact and lift the valve member from the valve seat at the point of maximum expansion of the chamber whereby the differential pressure is removed from the valve member and the bias means is able to rapidly withdraw the valve member completely from the outlet opening from the chamber to allow the rapid and complete expulsion of the accumulated water therein in an optimal manner.

Abstract: A method and apparatus for operating a center pivot irrigation system including a plurality of span units, each having a drive carriage having a hydraulically driven motor means for operating associated carriage wheels in response to hydraulic fluid supplied thereto under pressure through hydraulic fluid lines from a source thereof, is operated by supplying hydraulic fluid at a selectable value of constant volume fluid flow to the system to drive the system at a selectable average speed about its center pivot, the flow rate of fluid to individual motor means of individual span units which are ahead or behind of a predetermined relative alignment with the other span units being varied in response to changes in angularity sensed between adjacent span units in both forward and backward directions relative to the direction of travel of the system about its center pivot while the constant volume fluid flow through the system is being maintained at a selectable constant flow rate. An improved hydraulic adjustable rate flow valve accommodates fluid flow in reversible directions while maintaining close control or metering capabilities over the fluid flow through the valve in either flow direction.

Abstract: A water operated control apparatus and method for operating a controlled device is associated with moisture sensing apparatus for sensing the level of moisture available at a location and operating the controlled device in response thereto. Moisture sensing means is disposed at the location and is adapted to selectively pass air therethrough when the level of moisture at the location falls to a predetermined level, or prevent the passage of air therethrough when the level of moisture rises to a predetermined level. A housing is operatively connected to the sensing means and to a supply of water. A diaphragm is disposed in the housing in a manner forming a chamber therein, the interior of the chamber being in fluid communication with air passing through the sensing means. In one embodiment of the apparatus, a drain line of relatively small internal diameter is also in communication with the chamber and drains water from said supply in a hanging column of water such that the weight of the column of water pulls a partial vacuum in the chamber under the diaphragm when air is not being passed therein by the sensing means, as when the moisture level is above the predetermined level. Air from the sensing means relieves the negative pressure generated by the hanging column of water when the moisture level falls below the predetermined level. In another embodiment of the apparatus, the weight of water in a drain line is used to produce a positive pressure over the diaphragm when air is not passed by the sensing means. Air passing out through the sensor when the moisture level falls below a predetermined level relieves the pressure on the diaphragm. Movement of the diaphragm in response to the changing air pressure in the chamber may be used to operate a valve controlling flow of water through the chamber, or electrical contacts or a mechanical connection associated with the diaphragm which may in turn be connected to a controlled device or devices.The water operated control method includes the steps of connecting a moisture responsive air valve in air flow communication with a chamber, establishing a vertical column of water in a conduit in fluid flow communication with the chamber, placing the chamber in air pressure sensing relation with an air actuated device and operating the device in response to variations in air pressure acting upon the device when air is not passed by the air valve compared to when air is passed by the air valve.
