Abstract: A method and system for formulating and dispensing a chemical product to a dispense location is disclosed. The chemical product is formulated using one or more chemical concentrates. The chemical concentrates may be stored in concentrate containers and provided to a formulator by associated concentrate pumps. The concentrates are pulled from the containers through a manifold and to the formulator. The formulator discharges the chemical concentrates through a dispense hose having an outlet valve to the dispense location. The dispense location may be a jug or a drum. A flow meter connected between the formulator and the dispense hose. The flow meter monitors the component chemical concentrates flowing through the dispense hose and measures volumetric information associated with each component chemical concentrate. A flow controller analyzes the volumetric information generated by the flow meter and controls the volume of each component chemical concentrate dispensed to the dispense location.

Abstract: A turbine assembly includes a plurality of rotor blades comprising a root portion, an airfoil having a pressure sidewall and a suction sidewall, and a top portion having a cap. An outer shroud is concentrically disposed about said rotor blades, said shroud in combination with said tip portions defining a clearance gap. At least one circumferential shroud leakage discourager is disposed within the shroud. The leakage discourager(s) increase the flow resistance and thus reduce the flow of hot gas flow leakage for a given pressure differential across the clearance gap to improve overall turbine efficiency.

Abstract: A method is described for improving the cooling effectiveness of a fluid which flows through a row of passage holes in a substrate (e.g., a turbine component), out to a high-temperature surface of the substrate. The method involves forming a slot over the holes, within the high temperature surface of the substrate. The slot can be formed within protective coatings applied over the substrate. Alternatively, it can be formed partially within the substrate, and partially within the protective coatings. Movement of a film coolant through the substrate and into the slot results in greater cooling effectiveness. Related articles are also described.

Abstract: An apparatus and method for programming a controller to vary the concentration set-point of an additive as a function of time. The present invention insures that the additive is injected to the machine at proper times to allow for optimum efficiency and lowest cost. To vary the set-point according to the input parameters, the invention combines the features of a data entry device, a microprocessor, a clock, a controller, and sensors into one unit. The user may enter a time setting and set point into the controller, along with control parameters which allow the machine to control the additive injection based on different user-defined scenarios. The microprocessor then reads the settings and outputs an appropriate set-point value from the microprocessor to the controller. Thus, the user can manually or automatically change the response function if and when conditions change.
