Patent number: 7757966Abstract: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. In one embodiment, the control flow is applied at the desired circumferential location by the action of a rotting disk with a flow passage of a size that spreads the jet the desired amount. The size of this flow passage may be controlled by using two overlapping disks with large holes in each. By rotating one disk relative to the other, the size of the resultant passage can be modified.Type: GrantFiled: December 11, 2006Date of Patent: July 20, 2010Assignee: Utah State UniversityInventor: Barton L.

Patent number: 4784329Abstract: A portable lawn sprinkler comprising a housing assembly having means defining a fixed horizontally extending water inlet having a female hose fitting on the exterior end thereof and a spaced fixed annular wall providing an interior periphery defining an annular vertically opening water outlet. A speed reducing unit is mounted within the housing assembly. An impeller is drivingly associated with the input shaft of the speed reducing unit in a position to be rotated by water under pressure flowing from the inlet to the outlet. A rotary water distributor is fixed to the output shaft of the speed reducing unit disposed in water communicating relation with the outlet. An annular member is mounted for axial movement within the annular water outlet and in surrounding relation with the output shaft and has an exterior periphery disposed within the interior periphery of said fixed annular wall.Type: GrantFiled: June 17, 1986Date of Patent: November 15, 1988Assignee: L. R. Nelson CorporationInventor: Lawrence P. Heren

Patent number: 4702417Abstract: A water sprinkler which includes a casing and an oscillatory sprinkler head mounted on the casing. The casing includes a water inlet and two water outlet paths. Within the casing there is a structure which cyclically connects the water inlet first to one outlet path and then to the other. The oscillatory sprinkler head includes two spray nozzles which direct water generally tangentially. The nozzles are arranged so that the reaction force when water flows from one nozzle rotates the sprinkler head in one direction and when water flows from the other nozzle the sprinkler head is rotated in the other direction. Each nozzle is in communication with a respective one of the outlet paths. The angle through which the sprinkler head moves can be adjusted.Type: GrantFiled: January 21, 1986Date of Patent: October 27, 1987Assignee: Quentin John Seaton HartleyInventors: Quentin J. S. Hartley, Daniel G. Christen

Patent number: 4674521Abstract: Rinsing methods and apparatus employ a rotatable work support to spray rinsing liquid against a surrounding wall of a processing station. The rinsing liquid washes residual processing liquid from the surrounding wall of the processing station, whereby the work support performs a cleaning function in addition to its conventional processing function.Type: GrantFiled: May 20, 1985Date of Patent: June 23, 1987Assignee: Machine Technology, Inc.Inventor: Bernard Paulfus

Patent number: 4353506Abstract: A pop-up sprinkler assembly of the type including an internally driven rotary sprinkler head having a multiplicity of annularly spaced flow passages through which the flow of water is controlled by a fixed pattern plate. The assembly is provided with a manually operable pattern plate mounting member for adjusting the fixed cooperating relationship of the pattern plate with the rotary sprinkler head so that the orientation of the ground pattern area within which the water streams fall can be easily determined.Type: GrantFiled: September 15, 1980Date of Patent: October 12, 1982Assignee: L. R. Nelson CorporationInventor: Jerry R. Hayes

Patent number: 4219155Abstract: A high-pressure water cleaning device has an enclosure with an open bottom for movement over a floor surface and floor gratings. The cleaning device may be stationary, with objects to be cleaned moved past the enclosure. A rotating seal includes an upright spindle within the enclosure and secured thereto having an axial bore with a high-pressure water inlet and a series of radial discharge ports. A rotatable tubular body is journalled upon the spindle and has an internal annular high-pressure chamber communicating with the discharge ports and a series of radial outlets communicating with the chamber. Tubular arms mounting nozzles are laterally projected into the outlets for rotation with the body, the nozzles being adjusted for delivering streams of high pressure water within the enclosure at high pressure onto floor surfaces and gratings. The tubular body is power rotated.Type: GrantFiled: August 21, 1978Date of Patent: August 26, 1980Assignee: NLB CorporationInventor: William G. Goerss

Patent number: 4078727Abstract: A rotatable nozzle construction comprises a fixed hollow shaft which has a passage extending therethrough for the flow of the fluid. The distributor head is rotatably mounted on the shaft and it has at least one radially extending distributor head flow passage with an inner end which communicates with a radially extending portion of the shaft flow passage and an outer end which communicates with an annular passage defined around the periphery of a nozzle holder which is rotatably mounted at the periphery of the distributor head. The nozzle holder includes a generally radially extending distributor flow passage which terminates in a nozzle discharge which is at right angles to the axis of the shaft. The nozzle holder may be rotated on the distributor head so as to position the nozzle at any desired angle and the nozzle holder may be locked in the selected position.Type: GrantFiled: August 2, 1976Date of Patent: March 14, 1978Assignee: Woma-Apparatebau W. Maasberg & Co. GmbHInventor: Horst Lingnau
