Abstract: The claimed invention relates to a method for determining the extent of an oxidation reaction of a coated metallic turbine component within a turbine, comprising determining a plurality of reference oxidation rates for a plurality of locations on the turbine component for a plurality of different turbine operating conditions. The invention also relates to selecting an appropriate oxidation rate from a family of reference oxidation rate data and estimating the oxidation of the coated turbine blade or vane.

Abstract: A method of depositing a catalytically reactive coating to a substrate including selecting a target light off temperature for a predetermined catalytic combustion environment, selecting a thermal barrier coating composition, selecting a catalytic material and codepositing the thermal barrier coating composition and the catalytic material onto the substrate in proportions selected to produce the target light off temperature when exposed to the combustion environment. The method may include controlling the codepositing step to cause the thermal barrier coating composition to interact with the catalytic material to produce a phase having a light off temperature different from the respective light off temperatures of the thermal barrier coating composition and the catalytic material. A catalyst element may include a substrate and a first layer comprising a thermal barrier coating composition and a catalytic material throughout its depth disposed over a first portion of the substrate.

Abstract: A process for the production of a mono-olefin from a feedstock comprising a paraffinic hydrocabon which process comprises a) partially combusting at a pressure of at least (15) barg a mixture of the hydrocarbon feed and a molecular oxygen-containing gas in contact with a catalyst capable of supporting combustion beyond the normal fuel rich limit of flammability where they are reacted to form a product comprising one or more mono-olefin(s), carbon monoxide and hydrogen and b) recovering the one or more olefin(s).

Abstract: A nozzle assembly for enlarging an inground passageway produced by, for example, a boring device is disclosed herein. The nozzle assembly is comprised of a longitudinally extending nozzle body defining an interior cavity adapted to receive fluid under pressure from an external source and at least one arrangement of outwardly facing adjacent stepped surfaces which provide longitudinally spaced cutting jets directed normal to the movement of the boring device and nozzle assembly as the latter moves through a previously provided passageway in order to progressively enlarge the passageway.

Abstract: Method and apparatus are disclosed for concurrently thermocompression bonding a plurality of lead frames to a plurality of planar articles. In operation, a plurality of lead frames are referenced to a plurality of unheated bonding tips and to the associated metallized bonding sites on a first side of a plurality of planar articles. The bonding tips are then simultaneously activated to independently move the referenced lead frames and articles in a first direction to engage the second side of each article with a heated thermode, and apply a sufficient compressive force to bond the leads of each lead frame to the associated bonding sites on the referenced article. The bonding tips are then returned to their initial or starting position.
