  • Patent number: 10420294
    Abstract: A valve assembly includes an inlet and an outlet, and has a first state where liquid is stopped from flowing from the inlet towards the outlet, a second state where liquid is released to flow from the inlet towards and out of the outlet, and a terminal state where after flowing out of the outlet, the liquid is stopped form flowing out of the outlet. An incoming command triggers the valve assembly from the first state towards the second state and, at or after reaching the terminal state, the valve assembly transmits an outgoing command.

  • Patent number: 10182524
    Abstract: Disclosed are a method and apparatus for blending wastewater with fresh water for fertigation of a crop. In one embodiment, the wastewater and the fresh water are blended at a predetermined flow ratio through a blending valve to obtain a blended stream. A logic based controller controls the blending valve to set a predetermined flow ratio according to the electricity conductivity (EC) of the blended water stream. The blending, measuring and adjusting steps form a feedback loop so as to maintain the blended stream at a target EC value.

  • Patent number: 10172302
    Abstract: A drip irrigation emitter includes first and second members and a deformable membrane. The membrane is located between the members, and pins that are located on the first member are received within holes formed in the second member. End portions of the pins that project out of the holes are deformed and by that press the first and second members together and compress the membrane.

  • Patent number: 9968949
    Abstract: A pulsating irrigation device is provided that transforms a fluid flow entering the device to an intermittent pulsating fluid flow that is ejected from the device. The device has a chamber and at least one compressible member in pressure contact with the chamber. The compressible member compresses to assist the formation of the pulses ejected from the device and the fluid within the chamber is substantially sealed from contact with the interior of the compressible member.

  • Patent number: 9772057
    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.

  • Patent number: RE47697
    Abstract: An irrigation pipe formed from a sheet that is rolled into a tube about a longitudinal axis of the sheet. The pipe has a watertight layer and a fabric layer. The fabric layer comprises a first fiber arrangement including first main fibers having a first orientation and a second fiber arrangement including second main fibers having a second orientation. The first and second orientations are transverse relative to each other and to the longitudinal axis when viewed in the sheet before it is rolled.
