    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: An irrigation pipe (10) with a plurality of connector elements (14) adapted for attachment of lateral branches thereto, where the connector elements (14) are integrally fitted to the pipe's wall during the manufacture. Connector elements (14) may be fitted open and be adapted for closing after manufacture if not intended for use, or may be fitted closed and be adapted for opening after manufacture to enable the attachment.
    A method of production of such irrigation pipe (10) from a strip of flexible weldable or bondable material includes fitting integrally the connector elements (14) to predetermined locations on the strip, with or without punching the strip; bending or twisting the strip so as to juxtapose or overlap lateral edges thereof; and welding or bonding integrally the edges so as to obtain a closed pipe section.
