Patent number: 11505354Abstract: A packaging/inspection system is provided for a nozzle pivot package including a collection of nozzles in various nozzle sizes. The packaging/inspection system includes a shelf assembly with a plurality of compartments, an operator load track, a verification section downstream of the operator load track, a marking section downstream of the verification section, and an operator unload track downstream of the marking section. Each compartment may store nozzles of a specific nozzle size. Features of the shelf assembly alert the operator as to which compartment should be accessed and how many nozzles from the compartment are required.Type: GrantFiled: February 8, 2021Date of Patent: November 22, 2022Assignee: NELSON IRRIGATION COPORATIONInventors: Theodore J. Bren, Craig B. Nelson, Paul D. Davisson

Patent number: 7032836Abstract: A sprinkler head includes a base; an elongated stem having an inlet supported within the base; a nozzle and a stream deflector supported within the stem, the nozzle and stream deflector cooperating to define an arcuate orifice; a water distribution plate supported on one end of a shaft extending upwardly from the base, the water distribution plate located in axially spaced relationship to the nozzle and adapted to be impinged by a stream emitted from the nozzle. An externally threaded sleeve is fixed to an opposite end of the shaft; and an elastomeric throttle control member constructed with a smooth through-bore is engaged over the externally threaded sleeve to self-tap along the previously smooth bore. The throttle member is prevented from rotating such that rotation of the shaft causes the throttle control member to move axially relative to a flow restriction portion in the inlet, to thereby adjust flow rate through the stem and the nozzle.Type: GrantFiled: August 6, 2003Date of Patent: April 25, 2006Assignee: Nelson Irrigation CorporationInventors: George Sesser, Lee A. Perkins, Theodore J. Bren

Patent number: 6920907Abstract: A process for forming irrigation drip tape includes, broadly, the steps of a) supplying a longitudinally continuous strip of flexible plastic material in a first direction; b) heating a narrow band of the strip along a longitudinal axis thereof; c) depositing a continuous bead of material on an upper surface of the strip, along the narrow band, while the strip moves in the one direction; d) cooling the strip and the bead; e) folding the strip longitudinally so that the longitudinal edges overlap; and f) sealing said longitudinal edges to form a tubular drip tape with a longitudinal, overlapped seam, with the bead extending parallel to the seam and in opposed, facing relationship thereto.Type: GrantFiled: December 13, 2002Date of Patent: July 26, 2005Assignee: Nelson Irrigation CorporationInventors: Charles R. Harrold, Theodore J. Bren, Jr.

Patent number: 6620278Abstract: A method of forming tubular irrigation drip tape includes the steps of a) extruding a web of material having a pair of longitudinally extending, substantially parallel marginal edges; b) heating a center area of the web between and substantially parallel to the marginal edges utilizing a first focused infrared heating device; c) applying one or more secondary flow path components to the center area; d) heating the marginal edges, utilizing a second and third focused infrared heating device; e) folding the web such that the marginal edges overlap to form a seam; and f) applying pressure to the seam.Type: GrantFiled: November 9, 2000Date of Patent: September 16, 2003Assignee: Nelson Irrigation CorporationInventors: Charles R.
