Patent number: 8789768Abstract: A variable arc sprinkler may be set to numerous positions along a continuum to adjust the arcuate span of the sprinkler. The sprinkler includes a nozzle body and a valve sleeve that helically engage each other to define an arcuate slot that may be adjusted at the top of the sprinkler to a desired arcuate span. The sprinkler may include a flow rate adjustment device that may be adjusted by actuation or rotation of an outer wall portion of the sprinkler. Rotation of the outer wall portion may cause a throttle control member to move axially to or away from an inlet, or may cause one or more restrictor elements to open or close, to control the flow rate of the sprinkler.Type: GrantFiled: November 21, 2011Date of Patent: July 29, 2014Assignee: Rain Bird CorporationInventors: Steven Brian Hunnicutt, Samuel C.

Patent number: 7802701Abstract: Current designs of dispensers often do not allow for proper ventilation. Additionally, current designs often do not permit proper liquid sealing during shipment. The disclosed apparatus can overcome these shortcomings. This foam dispenser comprises a container, a cylinder device, a collar connected to the cylinder device, the collar operably connecting the container with the cylinder device, and a seal located on the collar, wherein the seal expands under compression to a locked position to create an airtight and liquid tight seal substantially preventing air and liquid from entering or exiting the cylinder device.Type: GrantFiled: January 13, 2006Date of Patent: September 28, 2010Assignee: Rieke CorporationInventors: Rowshan Jahan, David VanZuilen

Patent number: 7575123Abstract: A container and closure combination according to one embodiment of the present invention includes, as part of the closure, a tamper-evident band. The container includes a neck portion defining a dispensing opening and including an A diameter stop. The tamper-evident closure includes a closure body and the tamper-evident band is connected to the closure body by a plurality of frangible elements. A plurality of locking tabs are included as part of the tamper-evident band and are constructed and arranged to abut up against the A diameter stop upon retrograde rotation of the closure body from the container neck. The tamper-evident band further includes a radially inwardly extending ridge that is constructed and arranged to prevent repositioning of a plurality of the locking tabs to an orientation wherein the plurality of locking tabs would avoid abutment with the A diameter stop.Type: GrantFiled: January 19, 2005Date of Patent: August 18, 2009Assignee: Rieke CorporationInventors: Richard A.

Publication number: 20090188988Abstract: A spray nozzle and method are provided in which fluid flow through the nozzle is inverted and in which a portion of a nozzle body may be rotatable adjusted to distribute water in a desired arc of coverage. Water first flows upwardly through the nozzle body, into an adjustable arcuate chamber defined by a helical interface in the nozzle body, is inverted, and is redirected downwardly through the nozzle body. Water may flow upwardly through a first set of flow passages and downwardly through a second set of flow passages. Water is directed downwardly against a distribution surface having an uneven surface profile for improved water distribution to terrain near to and distant from the nozzle. The water is directed downwardly against the distribution surface in the nozzle body and outwardly to surrounding terrain. The flow passages may be adapted to provide a matched precipitation rate for nozzles with different throw radiuses.Type: ApplicationFiled: April 3, 2009Publication date: July 30, 2009Applicant: Rain Bird CorporationInventors: Samuel C.
