Abstract: A sprinkler including a first portion, a second portion arranged to rotate in reciprocating motion in a plane about a generally vertical axis relative to the first portion, responsive to impingement of a water stream on the second portion, at least a first magnet associated with the first portion and at least a second magnet associated with the second portion, the first and second magnets being magnetized to repel each other when in at least predetermined propinquity during relative rotation thereof in the plane.

Abstract: A delayed degradability drip irrigation pipe including a water conduit at a water conduit pressure and a plurality of drip irrigation outlets, each communicating with the water conduit and providing a water output at a pressure below the water conduit pressure, at least the water conduit being formed at least partially of a degradable material and also including a degradability delayer which provides a desired delay prior to failure of the water conduit but permits eventual degradation of the degradable material under predetermined conditions.

Abstract: Provided is a sprinkler configured for irrigation of a predetermined area, the sprinkler including a sprinkler body having a central axis. The body is formed with an irrigation inlet configured for receiving irrigation fluid, and a nozzle configured for discharging therethrough a directional jet of the irrigation fluid. The sprinkler further includes a reciprocal element configured for performing a reciprocal rotary motion about the central axis, and a deflecting member including an attachment mechanism for fixed attachment thereof to the reciprocal element. The deflecting member is formed with at least a first deflective surface, and is configured for performing a reciprocal rotary motion about the central axis together with the reciprocal element.

Abstract: A sprinkler including a first portion arranged to lie along a generally vertical axis, a second portion arranged to rotate about the generally vertical axis relative to the first portion and to be displaced along the generally vertical axis responsive to impingement of a water stream thereon, at least a first magnet associated with the first portion and at least a second magnet associated with the second portion, the first and second magnets being magnetized to repel each other at least generally along the generally vertical axis.

Abstract: A delayed degradability drip irrigation pipe including a water conduit at a water conduit pressure and a plurality of drip irrigation outlets, each communicating with the water conduit and providing a water output at a pressure below the water conduit pressure, at least the water conduit being formed at least partially of a degradable material and also including a degradability delayer which provides a desired delay prior to failure of the water conduit but permits eventual degradation of the degradable material under predetermined conditions.

Abstract: A sprinkler support including a base member configured to define an upward facing base surface, a recess extending across the base surface for receiving a water supply conduit, at least one resilient water supply conduit retaining finger located alongside one side of the recess for retaining the water supply conduit with respect to the base surface, at least one first resilient water supply conduit retaining finger receiving aperture formed in the base member for receiving the at least one retaining finger of another base member when stacked therewith in mutually 180 degree rotated, overall registration therewith, at least one second resilient water supply conduit retaining finger receiving aperture formed in the base member for receiving the at least one retaining finger of another base member when stacked therewith in mutually offset relationship therewith and a sprinkler support rod support portion, configured to receive and support an elongated sprinkler support rod.

Abstract: Provided is a rotary sprinkler that includes a housing, a rotatable irrigation head associated with a first magnet assembly, and a second magnet assembly associated with the housing and fitted with a rotary dampening mechanism. The first magnet assembly and the second magnet assembly are arranged with like poles facing each other so as to generate a repulsion force therebetween.
