Abstract: A gas turbine engine article includes a silicon-containing ceramic wall that has an external combustion gaspath side and an internal side that borders a cooling air cavity. The external combustion gaspath side has an associated combustion gas flow direction there along. An array of cooling holes extends through the silicon-containing ceramic wall and connects the internal side with the external combustion gaspath side. The cooling holes are oriented to discharge cooling air to the external gaspath side in a direction counter to the combustion gas flow direction.

Abstract: A particle beam detector is disclosed. The particle beam detector can include a particle beam receiving portion configured to convert particle beam energy to heat, and a plurality of temperature measuring devices disposed about the particle beam receiving portion. A location of a particle beam on the particle beam receiving portion can be determined by a temperature difference between at least two of the plurality of temperature measuring devices.

Abstract: A multi-step process of converting hydrocarbon fuel to a substantially pure hydrogen gas feed includes a plurality of modules stacked end-to-end along a common axis. Each module includes a shell having an interior space defining a passageway for the flow of gas from a first end of the shell to a second end of the shell opposite the first end, and a processing core being contained within the interior space for effecting a chemical, thermal, or physical change to a gas stream passing axially through the module. The multi-step process includes: providing a fuel processor having a plurality of modules stacked end-to-end along a common axis; and feeding the hydrocarbon fuel successively through each of the modules in an axial direction through the tubular reactor to produce the hydrogen rich gas.

Abstract: The present invention is a method and apparatus for measuring coupled flow, transport and reaction processes under liquid unsaturated flow conditions. The method and apparatus of the present invention permit distinguishing individual precipitation events and their effect on dissolution behavior isolated to the specific event. The present invention is especially useful for dynamically measuring hydraulic parameters when a chemical reaction occurs between a particulate material and either liquid or gas (e.g. air) or both, causing precipitation that changes the pore structure of the test material.

Abstract: A modified flapper valve for use in a toilet tank having a flexible extension structure attached at a first end to the valve and including a second end having at least one primary attachment point and a plurality of secondary attachment points, and a float element removably attachable to the extension structure and including a plurality of grooves for receiving the primary attachment point and the secondary attachment points of the extension structure, wherein the number of secondary attachment points of the extension structure engaging the grooves of the float element determines the distance of the float element from the valve. The extension structure can include a weight, either removable from or integral with, the extension structure. The valve can be mounted within the tank by conventional arms or by closing-moment exerting arms.

Abstract: A support assembly for a drag bucket includes lift lines and pull lines, each secured to a respective link plate pivotably secured to opposite sides of the bucket. Stops on the bucket side walls limit pivoting of the plates, whereby the bucket can selectively be maintained upright or in a dumping position by control of the lines.

Abstract: A multi-modal incubator of a non-circulatory type which isolates a controlled leakage incubator space from any fan to minimize noise within the space. The incubator has a bacterial filter and humidifier that can be readily maintained without it being necessary to disturb the enclosed space. For the purpose of isolating the fan the filter is always positioned in the ducting from the fan to the incubator space.

Abstract: A thermally-stable polyurethane encapsulating resin system which comprises a polyurethane prepolymer made by reacting a polyisocyanate with a polyol to form an isocyanate-terminated prepolymer. A second component of the system is a curing polyol for reacting with the prepolymer to form a polyurethane polymer having pendant vinyl groups provided by the use in said system of a hydroxy-terminated diene polymer. The system also contains a drying oil having an iodine number of up to about 200 in an amount sufficient to reduce the viscosity of the composition and improve filler loading. The system also contains a peroxide catalyst in an amount sufficient to promote cross-linking of the pendant vinyl groups of the intermediate polyurethane polymer to provide a thermally-stable polyurethane resin product, and promote the reaction of the drying oil into the product during curing.

Abstract: A process is described for the preparation of urethane prepolymers from hydroxy-terminated diene polymers and normally liquid, relatively non-volatile, aromatic polyisocyanates. The prepolymers are made at a temperature above about 150.degree. C. to provide urethane prepolymer products that resist the tendency to form multiple phases or layers upon storage at room temperature.

Abstract: An incubator which includes an opening which includes inwardly directed canopy like flanges or the equivalent so that upon the opening of the opening preferably using a slide door, air or oxygen from the controlled environment of the incubator can exit without a tendency for cold air to roll in over the bottom edge of the opening. To enhance this effect the incubator is of a type that allows a certain amount of leakage of the life support fluid even when the opening is ostensibly closed.
