Abstract: A connection assembly permits a make first and break last connection for primary power. The assembly includes a first pair of connectors, a second pair of connectors, and a compliance element associated with one of the first pair of connectors. The compliance element enables the first pair of connectors to mate prior to the mating of the second pair of connectors and to enable the first pair of connectors to disengage after the disengagement of the second pair of connectors.

Abstract: Castable and weldable nickel-base alloys that exhibit a desirable balance of strength and resistance to corrosion and oxidation suitable for gas turbine engine applications. The alloy contains, by weight, about 10% to about 25% cobalt, about 20% to about 28% chromium, about 1% to about 3% tungsten, about 1.6% to about 3.8% aluminum, about 0.4% to about 1.5% titanium, where the sum of aluminum and titanium is about 1.8% to about 5.0%, about 0.5% to about 1.5% columbium, 0.5% to about 1.5% tantalum, about 0.001% to about 0.025% boron, about 0.05% maximum zirconium, about 0.02% to about 0.15% carbon, with the balance essentially nickel and incidental impurities. The alloy may more preferably contain about 2.8% to about 3.8% aluminum where the sum of aluminum and titanium is about 3.0% to about 5.0%, or about 1.6% to about 2.8% aluminum, where the sum of aluminum and titanium is about 1.8% to about 4.3%.

Abstract: The present invention provides an improved method and system for real-time monitoring, validation, optimization and predictive fault analysis in a process control system. The invention monitors process operations by continuously analyzing sensor measurements and providing predictive alarms using models of normal process operation and statistical parameters corresponding to normal process data, and generating secondary residual process models. The invention allows for the creation of a fault analyzer directly from linearly independent models of normal process operation, and provides for automatic generation from such process models of linearly dependent process models. Fuzzy logic is used in various fault situations to compute certainty factors to identify faults and/or validate underlying assumptions.

Abstract: A fiber optic connector system in which two fiber optic connectors (44, 46) mate within a cabinet (12) and each one can be withdrawn for cleaning. Each connector is part of a connector assembly (40, 42) that includes a mounting bracket (54, 56) fixed to a corresponding daughterboard (20, 22). A motherboard structure (14) is mounted in the cabinet and has holes. Each daughterboard is slid into an opposite end of the cabinet until its connector passes partially through a motherboard hole and mates to the other connector. A pair of standoffs (101, 102) coupled to each connector limits inward movement of each connector to a position at which the tips of mating termini each lies halfway through an alignment sleeve.

Abstract: An aluminiding process that enables the cooling holes of an air-cooled component, such as a hot gas path component of a gas turbine engine, to be machined and then aluminized after all external surface coatings have been deposited. The aluminide coating is deposited using a slurry process capable of forming the aluminide coating on the component without damaging an existing ceramic coating on the component. The process involves applying an activator-free slurry containing aluminum particles that, when the component is sufficiently heated, melt and diffuse into the component surface to form the diffusion aluminide coating.

Abstract: An optic fiber connection system in which a first connector (12) on a daughter board (32) can slide towards a second connector (14) on a mother board (20) until the daughter board is latched and the connectors are fully mated, which assures proper mating despite overtravel or undertravel of the daughter board. The first connector has a frame (30) fixed to the daughter board and a first connector body (34) that is slideable within the frame (30), against the biasing of body springs (112), so the body does not have to move further forward while the frame and daughter board continue to move forward to a fully installed daughter board position.

Abstract: A shower curtain has thermochromatic-inked images thereon. Once the ambient temperature reaches near the thermochromatic ink's activation temperature, the thermochromatic-inked images appear, disappear or change color. Alternatively, the curtain may also contain inked images which are not affected by changes in ambient temperature and upon a sufficient change in the ambient temperature, the thermochromatic-inked images may appear as an accessory to the inked images or the thermochromatic-inked images may reveal or cover all or part of the inked images.

Abstract: The present invention relates to novel ultraviolet light absorbers of the benzoxazinone, oxanilide, benzylidene malonate, quinazoline and benzotriazole classes. The invention also relates to polymer and photographic compositions stabilized against the deleterious effects of light induced degradation which comprise the novel ultraviolet light absorbers.

Abstract: An optical fiber connector system includes first and second mateable connectors (12, 14) with fiber blocks (32,72) that hold optical fiber termini (50), wherein forward (F) movement of the second connector housing (70) toward the first housing (30) results in automatic latching together of the fiber blocks with the latches taking the forces of termini springs that have been partially compressed. The second fiber block (72) can slide within the second housing (70) between front and rear positions, and is held in the front position by a cam (90) that engages a free end (104) of a cam follower arm (103) of the second housing. As the connectors mate, a rigid second fiber block latch (100) deflects a resilient first housing latch end (62) and rides forward of it until faces of the blocks are close together.
