A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate three different substantially rectangular irrigation areas. The nozzle is adjustable to function as a left strip nozzle, right strip nozzle, and side strip nozzle. The strip irrigation setting may be selected by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a flow reduction valve to set the size of the rectangular irrigation areas and may be adjusted by actuation of an outer wall of the nozzle. Other specialty nozzles are provided having a fixed pattern template to irrigate a rectangular area, such as left strip, right strip, or side strip.

A multi-cone, multi-stage spray nozzle includes a nozzle body, a valve stem with a first valve head, and a second valve head attached to the first valve head. The first valve stem is biased into a closed position against a valve seat of the nozzle body by a bias device. The second valve head is continuously open. Upon the application of a first fluid pressure, which is less than a threshold fluid pressure, the bias device maintains the valve stem in the closed position while the second valve head is continuously open. And upon the application of a second fluid pressure, which is at least as great as the threshold fluid pressure, the valve stem moves to an open position while the second valve head remains continuously open.

A cleaning receptacle for cleaning a fueling nozzle used to transfer cryogenic fluid is disclosed. An example cleaning receptacle includes an outer body. The outer body includes an outer wall that extends circumferentially around a center axis of the cleaning receptacle. The outer wall has a first inner surface. The outer body includes a plurality of locating members extending inwardly from the first inner surface toward the center axis. The example cleaning receptacle includes a flow body. The flow body includes a second inner surface that defines a cavity and a lip at an outer end of the flow body. The example cleaning receptacle includes a spray body disposed at an inner end of the flow body. The spray body includes a spray head that defines a plurality of spray holes configured to spray air through the cavity of the flow body and onto surfaces of the fueling nozzle.

A pressure regulator for use in a sprinkler assembly including a riser and a sprinkler basket includes an outer sleeve mounted in the riser at an inlet thereof and a pressure responsive member, movably mounted in the outer sleeve and movable from an open position allowing flow of water between the top surface of the filter basket and the bottom edge of the pressure responsive member and up the riser and a closed position where the bottom edge of the pressure responsive member contacts the top surface of the filter basket to prevent water from flowing. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.

Nozzle assemblies (10) for spray guns are disclosed. The nozzle assemblies (10) generally include a fluid outlet (100) extending along a fluid axis (102), the fluid outlet (100) including a fluid aperture (104) and a fluid side wall (164) defining the fluid aperture (104), an atomizing aperture (108) adjacent the fluid side wall (164) and at least partially surrounding the fluid axis (102), an atomizing inlet (110) configured to receive a pressurized gas, and an adjustment member (150) located on the nozzle assembly (10) and movable to: (i) an atomizing position such that the atomizing inlet (110) is in communication with the atomizing aperture (108), and (ii) a non-atomizing position such that the atomizing inlet (110) is not in communication with the atomizing aperture (108). The foregoing nozzle assemblies (810) allow dispensing of fluid coating media in both spray and bead patterns with improved ease of cleaning, superior spray performance, and adaptability with existing spray gun platforms.

Rotary nozzles are provided that produce multiple discrete water streams for the irrigation of a substantially rectangular irrigation area. The nozzles may be designed to function as one of a left corner strip nozzle, right corner strip nozzle, and side strip nozzle. Each nozzle includes a particular type of nozzle housing with multiple flow channels oriented to irrigate a rectangular area in a certain position relative to the nozzle. The side strip nozzle includes one or more groups of two flow channels that are asymmetric with respect to one another. Further, each nozzle includes a deflector that rotates in either a clockwise or counterclockwise direction, depending on the position of the rectangular irrigation area relative to the nozzle. By matching deflector rotation with the position of the rectangular irrigation area, the uniformity of irrigation within the rectangular irrigation area can be increased.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

The invention relates to a device for injecting a fluid, in particular a cryogenic fluid, the device comprising a fluid feed head and a fluid dispenser body, detachably mounted on said feed head, said feed head comprising a groove for circulating the fluid fed to said body, said groove being closed when the body is mounted on the feed head and said groove being open when the feed head and the body are detached from one another.

Embodiments of the present disclosure relate to water fountain structures, and more specifically relate to modular fountain structures that include an adjustment bezel for changing a flow of water via an adjustable valve housed within them fountain structure. Adjustments to the valve to adjust the flow of water are effected by accessing the valve at the site of the fountain structure. The adjustment bezel or other manipulable device is incorporated with each fountain structure to provide control for flow of water emitted from the fountain, as the adjustment bezel is accessible without removal and/or disassembly of the fountain structure.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.
