Abstract: A filter arrangement includes a cleaning mechanism for cleaning at least one screen filter of the filter arrangement. The cleaning mechanism has a flush chamber, a central hollow core that extends through the flush chamber, and suction nozzles fitted to the core. The core extends between opposing axial ends that are located outside of the flush chamber in exposure to substantially similar pressures at least during a cleaning operation of the cleaning mechanism.

Abstract: A flow regulator for regulating a flow rate of water within at least a section of a water system, such as an irrigation system, includes a base member and piston member. The piston member is movable relative to the base member and includes at least one notch through which water can flow when passing through the flow regulator. Movement of the piston member towards and away from the base member, respectively, decreases and increases an area of the notch through which water can flow. An orifice member detachably coupled to the piston member and having an orifice member aperture through which all water flowing through the flow regulator must pass limits the cross-sectional area of an interior water passage within the piston member.

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: An irrigation pipe coupler can engage an open end of an irrigation pipe with its forward end. The coupler has a nipple and an outer collar. The nipple has an outwardly projecting barb and the collar surrounds the nipple and has an inwardly projecting bulge. The collar is slidably moved along the nipple between forward and rear terminal positions while being kept spaced radially outwardly from the nipple via a peripheral gap that is re-defined for each new position of the collar along the nipple. At each such new position, the gap has a narrow region measured in the radial direction where the collar is closest to the nipple and the narrow region gets smaller at least during at least part of the forward movement of the collar along the nipple. A window formed in the collar allows an operator to see an irrigation hose inserted into the gap.

Abstract: A drip irrigation emitter has first and second inlets through which liquid enters the emitter from an irrigation pipe, an outlet through which liquid exits the emitter, and a first flexible diaphragm portion seated on the second inlet and serving as a valve. Liquid at a pressure in the pipe that is below a predetermined level enters the emitter via the first inlet and travels along a first flow restricting path before exiting via the outlet and liquid at a pressure in the pipe that is above the predetermined level biases the first flexible diaphragm portion so that liquid can enter the emitter via the second inlet and travels along a second flow restricting path before exiting via the outlet.

Abstract: An aeration system for a bed of ore that is laid upon a basal layer has a gas source located upstream for supplying gas and aeration pipes that distribute the gas downstream to the bed. Each aeration pipe has spaced-apart gas emitters that distribute gas to the bed and the aeration pipes extend through the bed towards the basal layer.
