Abstract: High activity sulfur tolerant steam reforming catalysts are described comprising iridium, palladium or platinum supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina. The catalysts have improved activity over conventionally used catalysts in the presence of sulfur containing hydrocarbon fuels, particularly in a steam reforming environment. The catalysts have utility in autothermal, tubular, cyclic and adiabatic steam reforming processes.

Abstract: A workholder (6) has a contoured bonding surface (7), which essentially matches a contoured surface (4) of an airfoil (1). A plurality of studs (8) are disposed within a plurality of tapped holes (9) located about the workholder bonding surface. In operation, the studs are extended outwardly from the surface, and both the studs and bonding surface are contacted with a release agent (10). A curable resinous material (11) is applied to the bonding surface and studs, and an airfoil positioned next to the bonding surface, sandwiching the resinous material therebetween. After curing, a plurality of tapped holes (13) are formed in resin layer (11), with the extended studs fixedly positioning the airfoil relative to the workholder. Removing the studs provides heatless release of the airfoil from the workholder.

Abstract: A cable jacket slitting apparatus automatically pierces a cable jacket to a controlled depth at a tangent between two adjacent wires and automatically follows the tangent path as the jacket is slit. Two semicylindrical cam halves, (1, 23) disposed in aligned opposition within a housing (30), include longitudinal recesses (2, 24) having grooved sidewalls (4, 26) which conform to the helical contour of an electric cable jacket (5). The two cam halves are driven into mutual contact by a contoured surface (37) on the housing sidewall (31), the two cam half recesses forming a passage (48) which loosely grips the cable within the grooves in the sidewall. One of the cam halves carries a cutting rod (7) with a knife end (8) which pierces the cable jacket between a pair of adjacent wires. As the cable is drawn through the passage, the cam halves rotate about the longitudinal axis of the cable, helically slitting the jacket in a continuous helical direction around a longitudinal axis between a pair of adjacent wires.

Abstract: A method for testing electronic assemblies for resistivity to fluorocarbon solvent permeation. After attaching electronic components on host boards, sample assemblies are selected for testing. Fluorocarbon solvent is added to a container suitably sized to allow complete immersion of the samples. Fluorescent dye is added to the solvent and the solvent dye solution heated to the boiling point. Samples are immersed in the solution and initial time noted. The samples are withdrawn after a predetermined time interval, dried and wiped clean to remove excess solvent/dye from the outside of the components. The electronic assemblies are disassembled and illuminated by ultraviolet light. If dye is observed in an area thought to have been sealed, fluorocarbon solvent permeation is proven.
