Patent number: 10433501Abstract: A hybrid emitter of low discharge for water or solutions is inserted and welded into a pipe during the production phase. The hybrid emitter bears at its convex and cylindrical surface local protrusions that are covered completely from the pipe which is swelled locally. The water exits preferably from two nozzles that are created within the protrusions by the cutting-off of the tips, which protrusions protrude and after cutting-off, said nozzles eject the water almost cross-wise to two opposite directions and at short discrete distances left and right of the pipe. A method for welding of emitters and accessories into a pipe where the emitter or the hybrid one with or without protrusions on the outer surface, are inserted into the pipe during its production phase.Type: GrantFiled: April 13, 2017Date of Patent: October 8, 2019Inventors: Emmanuil Dermitzakis, Aristeidis Dermitzakis

Patent number: 9433157Abstract: The irrigation matter (1) of the present invention is inserted and welded in the interior of a drip irrigation pipe (2) during production thereof. It has a number of protrusions (8) arranged in a row emerging from a solid flat part/base (6) of the outer convex surface (7) of the emitter (1). The pipe (2) is locally swollen, covers and is welded both on the protrusions (8) and on their base (6), so that a unified welded assembly is formed between protrusions (8) and the pipe. The water outlets (10) are typically and preferably formed between the prismatic protrusions (8) by cutting off the tips of the protrusions (8) during passage of the drip irrigation pipe in a continuously rotating concave fraise (35) located at the end of the production line. Cutting takes place after the pipe has passed through a system of successive pairs of concave and convex rollers which squeeze it, stretch it and make it rigid, maintaining it in a flattened convex and bent form.Type: GrantFiled: September 20, 2011Date of Patent: September 6, 2016Inventors: Emmanuil Dermitzakis, Aristeidis Dermitzakis

Publication number: 20110089100Abstract: Self-cleaning filter for liquids with a basic element consisting of one cyclic elastic membrane 17 which covers completely the rims of a stable cavity 16. The rims of the cavity bear engraved shallow channels 25, while its concave part and bottom, bears great openings (26, 28). During the operation phase, the water passes under the membrane 17 and the shallow channels 25 of the cavity 16, leaves at the periphery of the rims or inside the channels the derbies 27 and through the openings 26 and 28 of the concave part and the bottom, comes out clean to the network 15 of the cleaned water. The water passing through the shallow channels 25, is subjected to a pressure loss with the result the membrane 17 to be significant bent, due to the pressure differences, and to be inserted sliding in to the cavity 16. By each interruption of the filter's operation, the membrane 17 returns in to its plan position scrapping and rejecting the derbies 27.Type: ApplicationFiled: June 24, 2009Publication date: April 21, 2011Inventors: Emmanuil Dermitzakis, Aristeidis Dermitzakis

Publication number: 20100155503Abstract: The emitter with potential of self cleaning of the water inlet filter, has incorporated filter in the inlet of water that consists of openings (2) with potential of bending of elements (1, Ia, 9) that create them if particular pressure is exercised from the one side of their surface. In case of complete blocking of the openings (2) of elements (1, Ia, 9) from foreign bodies that are transferred by water, a difference of pressure is developed between the two surfaces of these elements. This difference of pressure exercises forces and moments that bend or twist specific points of elements (1, Ia, 9) and as a consequence the continuity in the layer of foreign bodies that covers the filter is disturbed and interrupted. These forces are exercised constantly until the above mentioned difference of pressure is eliminated. In most systems, the deflection sag is controlled and limited by terminal limits (11).Type: ApplicationFiled: May 28, 2008Publication date: June 24, 2010Inventors: Emmanuil Dermitzakis, Aristeidis Dermitzakis
