Of Discharge Modification Of Flow Varying Patents (Class 239/11)
  • Patent number: 10693296
    Abstract: A computer-implemented method, according to one embodiment, includes: setting a target power demand corresponding to a consumer, and performing a process. The process includes: determining an actual power demand presented to the utility by the consumer based on a reward table, determining a current error, determining whether the actual power demand is adjustable in a direction that reduces the current error, reducing the current error by adjusting the actual power demand in response to determining that the actual power demand is adjustable in the direction that reduces the current error, and modifying the target power demand in response to determining that the actual power demand is not adjustable in the direction that reduces the current error. Determining the actual power demand includes measuring the power demand over a period of time in accordance with a process for measuring stability of power demand received from the utility.

  • Patent number: 10485190
    Abstract: A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver differing or variable depths of irrigation to two or more user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure the variable application depth, the speed may be changed during valve duty cycles. A farmer may define an irrigation plan that defines the variable rate irrigation (VRI) zones and also defines exclusion or no spray zones in which no irrigation should occur.

The base includes a conduit that extends through a central axis from a top surface to a bottom surface of the base. The base also includes a pedestal that defines a protrusion from the top surface, the pedestal having a planar top region substantially parallel to the planar bottom region of the base. The orifice member sits on the planar top region of the pedestal. The orifice member defines an intermediate conduit therethrough, the intermediate conduit in fluid communication with the base conduit. The orifice cap defines an upper conduit therethrough, the upper conduit in fluid communication with the intermediate conduit of the orifice member. The orifice cap is configured to secure the orifice member to the pedestal.

  • Patent number: 9265204
    Abstract: An irrigation system continuously monitors status of lawns or plants under its care and directs water to where it is needed when it is needed to maintain lawn or plant health. The system can significantly reduce water usage, unnecessary seepage, and runoff. A water nozzle with a pan and tilt capability can direct water where it is needed. An image sensor can continually take and analyze images of the lawns or plants to determine watering needs. The image sensor can also monitor where the water is landing while the irrigation system is delivering water to the lawns or plants. This information can be used to adjust the water delivery aim to ensure that the intended spots are accurately irrigated. A laminar flow nozzle with minimal flow dispersion can improve water deliver accuracy and detection of where the water lands.

  • Patent number: 9095867
    Abstract: A system for coating a target surface employs a bottle for containing the texture material and a spray pump assembly. A resilient member is supported by a pump housing to define an outlet opening. A collar member is supported by the pump housing. The resilient member is normally in an undeformed configuration in which the outlet opening defines a first cross-sectional area. Moving the collar member relative to the pump housing causes the collar member to act on the resilient member to deform the resilient member from the undeformed configuration to a deformed configuration in which the outlet opening defines a second cross-sectional area, where the second cross-sectional area is greater than the first cross-sectional area.

In one embodiment, the contoured surface of the tip includes at least one longitudinally oriented flat surface segment defined in the surface of the tip. In another embodiment, the contoured surface of the tip includes at least one longitudinally oriented concave surface segment defined into the conical surface of the tip of the adjustable needle valve.

  • Patent number: 8985483
    Abstract: Disclosed is a method and device to control a spray pattern produced from a spraying device consisting of a plurality of individual jets that form the resulting spray pattern. The trajectory of each individual jet is controlled by orienting the nozzle-like feature that produces each individual jet, thereby producing a variety of spray patterns. This is accomplished utilizing the flexible properties of elastomeric or rubber-like materials. In addition to allowing for deformation or movement to remove possible obstructions to the fluid flow, this flexibility property also permits for specific, controlled movements, whereby it is possible to control the trajectory of the fluid issuing from the device. These rubber-like materials can include specific features that allow the material to be deformed in a controlled fashion so as to predictably control the trajectory of the streams issuing from the individual nozzles.
