Patent number: 11857899Abstract: A filtering apparatus (100) having a filtering mode and a self-cleaning mode, the apparatus provided for filtering an upstream flowing fluid with filtering elements (20) in the form of a plurality of stackable discs during filtering mode utilizing a first flow direction, apparatus (100) also configured to self-clean the filtering elements (20) the apparatus (100) including an internal fluid diverter (110,210, 310) that is internal to the filter housing. The position of the internal fluid diverter determines the direction of fluid flow through the filter housing and the filter phase. The position of the internal fluid diverter is controlled with a controller disposed external to the filter housing that may be manipulated either manually or by automated means.Type: GrantFiled: May 8, 2019Date of Patent: January 2, 2024Assignee: Plas-Fit Ltd.Inventors: Uri Alkalay, Gilad Nahmias

Patent number: 11504725Abstract: A rotary sprinkler comprises a rotatable irrigation head with one or more nozzles, associated with liquid feed lines, which extend thereto from a sprinkler base housing, and further comprises a static biasing control base located below the irrigation head, e.g. between the sprinkler base housing and the irrigation head. The sprinkler can comprise a flow regulator arm, whose movement, at least indirectly, results in reducing the cross-sectional area of liquid flow towards at least one of the nozzles, and a flow deflector arm configured to interfere with a liquid jet discharged from at least one of the nozzles in order to affect the angle and range of the liquid jet. The static biasing control base can comprise an array of biasing elements, which can bias a cam follower configured to rotate together with the irrigation head and transfer its rotational displacement to the flow regulator arm and flow deflector arm, e.g. through respective gear elements.Type: GrantFiled: March 1, 2018Date of Patent: November 22, 2022Assignee: CLEVER WATER SPRINKLER TECHNOLOGIES LTD.Inventors: Uri Alkalay, Avihai Simner

Patent number: 9827514Abstract: A fluid flow accessory is provided for coupling to an opening formed in a wall portion. The fluid flow accessory includes a cup having an edge configured to engage a first surface of the wall portion; and a coupling member including coupling arrangement configured for coupling to the cup and a first flange configured to be inserted through the opening in a first orientation thereof with respect to the opening, and for abutting against a second surface of the wall portion in a second orientation thereof with respect to the opening, and a fastening member protruding towards the first flange and being disposed such that in the second orientation it engages a segment of the wall portion thereby limiting the displacement of the coupling member into the first orientation.Type: GrantFiled: February 24, 2015Date of Patent: November 28, 2017Assignee: YAMIT FILTRATION & WATER TREATMENT LTD.Inventor: Uri Alkalay

Patent number: 5695081Abstract: A modular shelving system which can be easily assembled and disassembled is disclosed. The system comprises: (1) vertical posts; (2) horizontal beams; (3) side horizontal braces; (4) connectors capable of being mounted on the vertical posts and having 1-4 identical ears protruding from the sides of the connector capable of being coupled to the horizontal beams and braces; and (5) shelf pieces which are positioned on the horizontal beams. The width of the side horizontal braces is substantially similar to the width of the connectors, thus forming one continuous surface.Type: GrantFiled: December 6, 1995Date of Patent: December 9, 1997Assignee: Julius Engineering Ltd.Inventor: Uri Alkalay
