摘要： A protected article includes a nickel-base superalloy substrate, an interlayer overlying the substrate, and a protective layer overlying the interlayer. The protective layer has a composition comprising at least one of rhodium, platinum, palladium, and ruthenium. In one composition, palladium is present in an amount of from about 1 to about 41 atomic percent; platinum is present in an amount of about (40+atomic percent palladium) atomic percent for palladium ranging from about 1 atomic percent to about 14 atomic percent and up to about 54 atomic percent for palladium ranging from about 15 atomic percent up to about 41 atomic percent; rhodium is present in an amount of at least about 24 atomic percent; zirconium, hafnium, titanium, and mixtures thereof are present in an amount of from zero up to about 5 atomic percent; and ruthenium is present in an amount of from zero up to about 5 atomic percent, balance impurities. The interlayer has a coefficient of thermal expansion intermediate between that of the substrate and that of the protective layer. The protected article is fabricated by furnishing the substrate, applying the interlayer over the substrate, and applying the protective layer over the interlayer. The application of the protective layer may be, for example, by welding or attachment of a solid piece.

摘要： A foldable box sealing machine includes an upright main frame unit, an upper taping unit mounted on the main frame unit, a platform unit having a base panel mounted rotatably on the main frame unit below the upper taping unit, a lower taping unit disposed below the upper taping unit. The base panel is rotatable between a first position where the base panel is substantially horizontal, and a second position where the base panel is substantially vertical.

摘要： A class AB amplifier includes: a voltage amplifier stage operating off a first source voltage, and amplifying a differential input voltage to produce a first amplified voltage; a level shift stage coupled to the voltage amplifier stage and adjusting a direct current level of the first amplified voltage to produce a first shift voltage; and a power amplifier stage coupled to the level shift stage, operating off a second source voltage, and converting the first shift voltage to produce a first output current. The second source voltage is larger than the first source voltage.

摘要： An apparatus for growing and harvesting a tangled mass composed of sprouted seed grain includes a plurality of overlying immobile, substantially planar surfaces having a length. Each surface is configured to receive a layer of seed grain that is permitted to grow for a predetermined period of time on each surface, the layer of seed grain becoming a continuous tangled mass of sprouted seed grain. An extraction device removes the mass from each surface. A cleaning device removes debris from each surface prior to each surface receiving a subsequent layer of seed grain.

摘要： A bond coat process for thermal barrier coatings. The method includes, after cleaning and masking the external surface of the substrate, first applying a layer of NiCrZr alloy to the external surface of the substrate using a sputter coat or other suitable process. Aluminum is then applied to the substrate, using either a vapor phase aluminization (VPA) or chemical vapor deposition (CVD) process, wherein aluminum diffuses into the NiCrZr alloy layer wherein a diffusion layer is formed by the aluminum with the substrate material on the internal surface of the substrate. The coated substrate may then be subjected to a heat treatment in a protective atmosphere to further allow diffusion of the aluminide into the NiAlCrZr diffusion layer. The substantially Al outer layers of the NiAlCrZr diffusion layer, and the diffusion aluminide layer, will provide an aluminum source for the surface, which will oxidize to form a tightly adherent aluminum scale. The diffusion aluminide layer and the high Al portion of the NiAlCrZr diffusion layer will also function as a source of aluminum which will provide a reservoir to heal the alumina scale during operation.
