Abstract: This invention relates to coatings for a metal or non-metal substrate comprising (a) a thermal sprayed bondcoat layer applied to the substrate, and (b) a thermal sprayed ceramic layer applied to said bondcoat layer; wherein said coating has a helium leak rate of less than 6×10?6 standard cubic centimeters per second. The thermal sprayed bondcoat layer comprises (i) a thermal sprayed inner layer alloy, and (ii) a thermal sprayed outer layer alloy. The inner layer alloy is thermally sprayed from a powder having a mean particle size of 50 percentile point in distribution of from about 5 microns to about 50 microns. The outer layer alloy is thermally sprayed from a powder having a mean particle size of 50 percentile point in distribution of from about 30 microns to about 100 microns. The coatings are useful for extending the service life under severe conditions, such as those associated with metallurgical vessels' lances, nozzles and tuyeres.

Abstract: A method of generating electricity in synthesis gas in which a fuel is combusted in a gas turbine to generate the electricity that at least about 60 percent by volume is derived from a source independent of the synthesis gas. The synthesis gas is produced by reacting a hydrocarbon stream, by for example, partial oxidation, autothermal reforming or steam methane reforming. After the synthesis gas stream is cooled, heat is transferred from the heated synthesis gas stream to the fuel prior to combustion in the gas turbine. All or at least a portion of the heat is transferred at a temperature no greater than about 500° F. and at a flow ratio of the fuel to the gas turbine to the synthesis gas stream from at least about 1.5. The heating of the fuel to the gas turbine lowers fuel consumption and thereby the total expenses involved in generating electricity and syngas.

Abstract: A gaseous process stream that can be directed into a workspace or toward a workpiece is formed by feeding fuel, oxidant and process material into a thermal nozzle. The fuel combusts in the thermal nozzle with the oxidant and with combustible components, if any, of the process material, to form the gaseous process stream which is emitted from the thermal nozzle at high and controllable velocity and momentum.

Abstract: A switching apparatus and electro-mechanical latching system includes an elastomeric button with independently movable electrically conducting spring plates mounted to the button. The button includes a plurality of elastomeric posts extending from an inboard surface thereof for retaining the spring plate to the button. A leadframe is disposed in the base and includes electrical tracks for communicating with a vehicle computer. Each spring plate includes a plurality of cantilever springs. When the button is depressed, the cantilever springs of the spring plates come in contact with electrical tracks to complete a circuit. The completion of the circuit causes a signal to be sent to a vehicle computer, which signals a motor to release the automotive vehicle door latch.

Abstract: A switching apparatus and electromechanical latching system includes an elastomeric button with independently movable electrically conducting spring plates mounted to the button. The button includes a button cap including a relatively high durometer material and button walls including a relatively low durometer button material, such that the button walls collapse and the button cap generally maintains its shape when pressure is applied to the button cap.
