Disclosed herein are methods and systems for improving performance of sprinkler control systems using aggregations of flow controllers. As an example, to facilitate control of multiple controllers, a system may generate a virtual flow controller by aggregating the two or more flow controllers. A schedule for the virtual controller is set or received and then translated into schedules for the aggregated controllers. In another example, schedules may be set for individual watering zones, which are then translated into watering schedules for flow controllers corresponding to the zones. The system then transmits these schedules to a respective flow controller, which then carries out an irrigation routine according to the schedule.

A retractable center feed injection device can be employed to feed residual oil into a coke drum as part of a delayed coking process. The retractable center feed injection device can include a housing within which the injection nozzle slides between an extended and a retracted position. A feed inlet is positioned on an opposite side of the coke drum from the retractable center feed injection device. When in the extended position, the injection nozzle can couple with the feed inlet and thereby form an extension of the feed inlet into the center of the coke drum. In this way, the residual oil never flows through the housing.

A method and alignment system for minimizing errors in the deposition of films of tailored thickness. A first position on a stage is identified for optimal placement of a downward looking microscope (DLM) and an upward looking microscope (ULM) when alignment marks on the DLM and ULM are aligned, where the DLM is attached to a bridge and the ULM is attached to the stage. A second position on the stage is identified when the ULM on the stage is aligned with the alignment marks on a metrology tool. A surface of a chucked substrate affixed to the stage is then measured. A map between a substrate coordinate system and a metrology coordinate system may then be obtained using the measured surface of the chucked substrate with the first and second positions.

The invention relates to a component of a gaseous fire suppression system. A concealed extendable nozzle for gaseous fire suppression systems is mounted on a distribution pipe of a gaseous fire suppression system. The nozzle consists of a body with discharge openings and a cap. A rod of a nipple is mounted inside the body of the nozzle. The nipple rod has a variable outside diameter: at one end, the rod narrows and ends in a connecting thread, whereas at the other end, the rod widens. Meanwhile, the body has an opening of variable diameter, which permits movement of the nipple rod inside the body; the body of the nozzle has a widening on the outside. A cap is fastened to the body of the nozzle, and this connection is tightly sealed by a washer. The technical result is the even dispersal of a gaseous fire extinguishant inside a room.

In accordance with one aspect, a faucet-supplied irrigation system is provided having a container, coiled tubing in the container, a plurality of pop-up sprinklers in the container, and a plurality of connectors in the container for attachment to the tubing and sprinklers. The irrigation system includes an irrigation controller in the container and a pressure regulator in the container to regulate water pressure of the supply of water to the sprinklers from the faucet. The container is configured to maintain a plurality of the coiled tubing, pop-up sprinklers, connectors, controller and regulator in a predetermined arrangement within the container.

A device for use in OVJP and similar arrangements includes a print head movable in more than one degree of freedom with sufficient thermal insulation that there is little to no movement in the Z direction. One or more sensors may be used to monitor and adjust the distance between the substrate and the print head.

A sprinkler head of visual identification is disclosed. A housing includes a circumference wall, a cap enclosing the circumference wall, and an aperture member alternatively formed on the cap and the circumference wall for dispensing water. A first visual portion is arranged on the circumference wall of the housing and corresponds with the aperture member. A second visual portion, which is visually different from the first visual portion, is arranged on the circumference wall and adjoins the first visual portion. The first and second visual portions constitute the circumference wall of the housing together, a visual differentiation of the first recognition portion and the second one is offered in accordance with the arrangement of dissimilar art elements.

A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (“PR”) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (“SC”) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

A multi-purpose system is disclosed which utilizes a lawn sprinkler in the shape of a fire hydrant to provide a stimulus to a dog. A remotely programmable portable water sprinkler is provided, which can be programmed to run for a period of time for normal watering of a lawn, and it can be programmed to trigger and spray when a series of dog barks are detected. This spraying of water is intended to be a stimulus to the dog.

A housing selectively encloses a nozzle. The housing has a body that partially defines an interior space in which the nozzle is configured to be disposed. The housing also includes a cover assembly that selectively blocks a first aperture of the body and further defines the interior space. Additionally, the housing has a piston that is disposed in the interior space and secured to the nozzle. The piston defines a gas inlet, a liquid inlet, and an outlet fluidly connected to both the gas inlet and the liquid inlet. The housing further includes a biasing member attached to the piston. The biasing member is configured to exert a biasing force that biases the nozzle to a retracted position. The biasing member is further configured such that when pressurized gas flows through the body, the biasing force is overcome such that the nozzle is disposed in an extended position.
