In one embodiment, a pipeline interchange is described where a first product flows through a first pipeline and a second product flows through a second pipeline. In this embodiment, a first product automated analyzer is situated near the first pipeline to physical and/or chemically analyze the first product and generate first product data. Additionally, in this embodiment, a second product automated analyzer is situated near the second pipeline to physical and/or chemically analyze the second product and generate second product data. A pipeline interchange is connected downstream to both the first pipeline and the second pipeline, wherein the pipeline interchange blends the first product flowing through the first pipeline with the second product flowing through the second pipeline. A third pipeline is connected downstream to the pipeline interchange, wherein the third pipeline flows a blended product created from the blending of the first product and the second product in the pipeline interchange. A data analyzer is also positioned to interpret the first product data and the second product data and communicate adjustments to the flow of both the first product and the second product to achieve desired physical and/or chemical characteristics in the blended product.

In one embodiment, a process is taught where the process begins by flowing a first product through a first pipeline and flowing a second product through a second pipeline. In this embodiment, the first product in the first pipeline is analyzed with a first product automated analyzer that is capable of physical and/or chemically analyzing the first product in the first pipeline and generating a first product data. Additionally, in this embodiment, the second product in the second pipeline is analyzed with a second product automated analyzer that is capable of physical and/or chemically analyzing the second product in the second pipeline and generating a second product data. The process then produces a blended product by mixing both the first product and the second product within a pipeline interchange which is connected downstream to both the first pipeline and the second pipeline. The blended product then flows from the pipeline interchange to a third pipeline that is connected downstream of pipeline interchange. The first product data and the second product data is then interpreted in a data analyzer by comparing the physical and/or chemical characteristics of the physical and/or chemical characteristics of the first data to an optimal first data and the physical and/or chemical characteristics of the second data to an optimal second data. The data analyzer then determines the adjustments in the flow of the first product and the flow of the second product to achieve optimal blended data from the blended product. The adjustments are then communicated to adjust the flow of the first product in the first pipeline and the flow of the second product in the second pipeline.

Adjustable venturi assemblies and methods of using adjustable venturi assemblies are disclosed. In one aspect, a venturi assembly for injecting a secondary fluid into a primary fluid flow path is provided. The venturi assembly comprises a nozzle, a constricted section in fluid communication with the nozzle, a secondary fluid conduit in fluid communication with the nozzle, and a flow adjusting device. The nozzle and constricted section together define the primary fluid flow path along a first axis. The secondary fluid conduit is for transporting secondary fluid from the secondary fluid reservoir to the constricted section along a second axis.

A system for mixing fire-suppressant gel with water on board an aircraft includes a gel reservoir mounted in the aircraft, a pump for injecting gel into a flow of water into an aircraft-mounted payload tank, and a control system for controlling gel-water mix ratios. The control system monitors water volume flowing into the water tank, and regulates the gel pump to inject gel in appropriate amounts to produce gel-water emulsions having precise gel-water ratios. Settings for the control system are set by the pilot before water flow water is initiated. Once the aircraft is in flight, the gel-water mixing process is automatically controlled through a trigger on the pilot's control stick. The aircraft may be a helicopter or fixed-wing aircraft adapted to load water from a lake or other source while in flight, or a fixed-wing aircraft adapted to load water on land from a pressurized water source.

A system and method for dividing a single mass flow into secondary flows of a desired ratio. The system and method include paths for the secondary flows that include a laminar flow element and two pressure sensors. The nonlinear relationship between flow and pressure upstream and downstream of the laminar flow elements can be transformed into a function comprised of the upstream and downstream pressure that has a linear relationship with the flow. This transformation allows for flow ratio control applications using signals from pressure sensors even if there is no information the fluid species and the flow rate into the flow ratio controller.
