Abstract: The invention relates to a blow mold (100) comprising a mold base (101) having a cavity (102) as the mold cavity, the cavity (102) having a bottom region (1), a center region (2) and a top region (3). When the blow mold (100) is closed, the center region (2) can be moved relative to the top region (1) and/or relative to the bottom region (3).

Abstract: A control system for a gas turbine includes a controller. The controller includes a processor configured to receive a plurality of signals from sensors disposed in the gas turbine engine system, wherein the gas turbine system engine comprises a compressor section fluidly coupled to a gas turbine section. The processor is additionally configured to derive a vanadium content in a gas turbine engine fuel based on at least one of the plurality of signals. The processor is also configured to determine if a control curve should be adjusted based on the vanadium content in the gas turbine engine fuel, and if it is determined that the control curve should be adjusted, then deriving an adjustment to the control curve based on the vanadium content, and applying the adjustment to the control curve to derive an adjusted control curve.

Abstract: A method of operating of a gas turbine engine to inhibit vanadic corrosion of the gas turbine engine is provided. The gas turbine engine burns a vanadium-contaminated fuel and includes a component configured to be in contact with combustion gases. The method includes introducing into a combustion system of the gas turbine engine a first oxide and at least one second oxide. The first oxide includes magnesium oxide, and the at least one second oxide includes at least one of aluminum oxide, iron (III) oxide, titanium dioxide, and silicon dioxide. The method further includes cleaning at least a portion of the component using a cleaning agent containing a liquid vector and at least one descaling material that is suspended in the liquid vector. The at least one descaling material is an inorganic material.

Abstract: An article comprises a first outer layer; a second intermediate layer; and a substrate; wherein the second intermediate layer contacts the first outer layer at a first interface and the substrate at a second interface. The first outer layer comprises Al2O3—TiO2 and the second intermediate layer comprises a functionally graded material. The functionally graded material comprises a composition proximate the first interface being substantially free of Al2O3—TiO2 and at the second interface having Al2O3—TiO2 in amounts substantially equal to the first outer layer.

Abstract: The IIT of the present invention consists of the following parts arranged in series along the optical axis of the IIT in the direction from the target being observed to the viewer's eye: a fiber-glass plate having a flat side facing the object and a concave side facing the viewer, a thin-film coating applied onto the concave surface of the fiber-glass plate which functions as a photo-cathode, an anode made in the form of a truncated cone with the narrow side facing the photo-cathode, and a flat luminescent screen made of glass with a luminescent coating. Unique parts of the IIT of the invention are a specially profiled and dimensioned anode and shutter electrode. The anode and the shutter electrode have specific relationships between the diameters and lengths of the portions from which this parts are composed.
