Abstract: A rotating sprinkler for intermittently emitting a liquid supplied by a pulsating device that forms pulses that have a beginning and an end. The sprinkler has a rotating portion that can rotate about an axis while emitting the liquid pulses to the outside environment. The sprinkler provides for rotation of the rotating portion during a portion of each pulse and for stopping rotation of the rotating portion during another portion of the pulse.

Abstract: A pulsating device has a chamber for receiving liquid entering the device and gas that occupies an initial volume in the chamber. The liquid entering the chamber compresses the gas and decreases the volume occupied by the gas, thereby increasing the pressure in the chamber. A valve is provided to open above a first threshold pressure to begin a pulse of liquid. The valve closes below a second threshold pressure to end the pulse. The pulsating device has an outlet gate that permits liquid in the chamber to exit the chamber when the pressure in the chamber is greater than the pressure outside the chamber.

Abstract: A drip irrigation pipe includes a drip emitter and a flap that is formed in the pipe wall by first and second grooves. The first groove is longer than the second groove and the flap remains connected to the pipe wall at two bridges. A pivot region of the flap extends between the two bridges and the flap is adapted to twist about the pivot region as liquid exits the pipe at the flap.

Abstract: A sprinkler irrigation stand for use with an irrigation pipe has a base placed below the pipe for being stabilized by the pipe. The pipe freely rests upon the base so that it may be lifted freely off the base or may inflate freely upwards in the case the pipe is a collapsible pipe. A riser of the stand for supporting a sprinkler may be attached to the pipe and slide up in relation to the stand when attached to a collapsible pipe that is inflated.

Abstract: A fluid flow regulator (20) comprising: a fluid inlet port (34) and a fluid outlet port (54); at least one open-faced flow control channel (60) defined by a planar bottom (62) and two sidewalls (64) that communicates with the outlet port (54) at a junction (66) and has a cross-section that decreases with distance from the junction; an elastic diaphragm (40); a support shelf (58) on which the diaphragm (40) seats and which supports the diaphragm (40) along a planar contour parallel to the bottom of each of the at least one channel (60); wherein to regulate fluid flow, with increasing inlet fluid pressure the diaphragm (40) covers portions of the open face that are farther from the junction (66) in a region where the cross-section decreases with distance from the junction (66).

Abstract: A filtration tank (10) with a central vertical axis x comprises: a first chamber (54), a second chamber (56) and at least one filter element (66). The first chamber has a first inlet (20) through which fluid to be filtered enters the tank and is designed so as to provide a swirling flow of the fluid to the second chamber. The second chamber (56) has a second inlet (60), in fluid communication with the first chamber (54), and an outlet (20) through which filtered fluid exits the tank, the outlet (2.0) being preferably disposed lower than the second inlet (60). The filter element {66) may be disposed in the second chamber and may have a portion capable of free undulation due to movement of the fluid in which it is disposed caused at least in part by the swirling of fluid entering the second chamber. The swirling may be obtained by centrifugal forces induced within the tank at least in a portion of a fluid flow path preceding the second inlet. The tank may be used in a filtration system including a fixed head pressure column and a pipe system for providing fluid to the tank and the column. The fixed head pressure column has a top portion open to the atmosphere, and is mounted on and in fluid communication with the pipe system, for eliminating the suction of dirt into the pipe system.
