  • Patent number: 6314343
    Abstract: An aircraft flight mode selector assembly utilizes computer-generated menus and soft wired bezel keys to enable the use of a greater number of flight modes to be accessed in a smaller space than is presently possible with a flight mode selector consisting solely of conventional dedicated switches, switch indicator lights, and hard wired selector panel assemblies. Serial bus connections between the flight mode selector assembly and the flight control computer in the aircraft reduce the amount of wiring needed for the flight mode selector assembly, as compared to present protocol which utilizes dedicated wiring for each dedicated switch in the aircraft flight mode selector. The use of computer-generated displays and menus permits easy expansion of the flight mode selector assembly without the need to add additional switches and switch indicator lights.

  • Patent number: 6306354
    Abstract: A fuel cell power plant, generally, has a fuel cell stack for electrochemically converting a hydrocarbon fuel into electricity. In order for the hydrocarbon fuel to be used by the fuel cell stack, it must be steam reformed into a hydrogen-rich process gas. This process gas has a carbon monoxide level that would be detrimental to the fuel cell stack, so the process gas is passed through a shift converter to decrease the carbon monoxide level therein prior to feeding the process gas to the fuel cell stack. In order to decrease the level of carbon monoxide without the need to increase the size of the shift converter catalyst bed, or lower the temperature of the process gas as it enters the shift converter to an undesirably low temperature, the shift converter design that utilizes an upstream adiabatic zone and a downstream actively cooled zone. The actively cooled zone is cooled by a pressurized water coolant which boils as it cools the process gas stream.

  • Patent number: 6287870
    Abstract: Formed constituents in an aqueous based fluid biologic material sample are separated from the aqueous constituent of the sample, and are concentrated in an examining instrument's focal plane where they can be examined under magnification. Examples of fluids that can be analyzed in this fashion include urine; cerebrospinal fluid; pleural fluid; ascites; fluids aspirated from cysts such as thyroid and breast cysts; cytologic specimens which have been placed in an aqueous fluid; platelet-rich plasma; and the like. The sample is placed in a chamber having a layer of a hydrophilic hydrogel covering a surface of the chamber. An opposite surface of the chamber is transparent, and may be formed by a microscope slide cover slip, or the like. The volume of hydrogel in the chamber is sufficient so that, when the hydrogel absorbs essentially all of the aqueous fraction of the sample, the hydrogel will expand and fill the chamber.

  • Patent number: 6262799
    Abstract: Centrifuged material layer volumes are measured and quantified during centrifugation of the material layers. The material layers are differentially highlighted by means of one or more supravital fluorescent dyes or stains which are admixed with the sample being analyzed. This kinetic quantification procedure is particularly useful in performing differential blood cell and platelet counts. The blood sample is centrifuged while being subjected to an intense filtered strobed light source at two different wavelengths. At least one photometric cell layer compaction measurement is made in conjunction with the light flashes so as to record a degree of cell layer compaction as the sample is being centrifuged. In certain cases, after several successive cell layer compaction readings are derived, a compaction curve is identified and the ultimate degree of cell layer compaction is calculated from the derived compaction curve prior to the achievement of the ultimate degree of cell layer compaction.

  • Patent number: 6258476
    Abstract: Solid polymer membrane fuel cell water which collects on the oxidant side of the membrane is removed from the active area of the cells in a fuel cell power plant by being absorbed into porous carbon bodies, one of which contacts the membrane. Some of the treated carbon bodies can also be used to supply water to the anode side of the membrane in order to minimize anode side membrane drying. The pores in the carbon body are partially filled, or coated, with precursors of metal oxyhydroxide compounds, which, when converted, will impart increased wettability and water absorption capacity to the carbon body. Hydroxides of the filler compounds are applied to the carbon body and are heated to convert them into oxyhydroxides. As used in this document, the term “oxyhydroxide” includes oxyhydroxides, oxyhydroxide hydrates, and oxide hydrates. Processing temperatures are low enough so as to not subject the bodies being impregnated to destabilization.

  • Patent number: 6258330
    Abstract: A fuel gas reformer assembly for use in a fuel cell power plant includes fuel gas passages, some of which contain a particulate alumina packing in which a vaporized steam-hydrocarbon fuel stream mixture is heated. The walls of the fuel gas passages are provided with an alumina coating which protects the walls of the passages from corrosion. The alumina coating of the walls, and alumina packing are both overlain by an alkaline earth metal oxide layer, such as a calcium oxide layer, that acts to limit carbon build-up on the surfaces of the coated passage walls. Limiting of carbon build-up in the reformer passages prevents premature clogging of the passages. The carbon build-up-limiting layer is formed on components of the reformer passages by applying a water-based slurry of alkaline earth metal compounds to the reformer passage surfaces, and then drying the slurry so as to solidify it.

  • Patent number: 6235536
    Abstract: Formed constituents of a quiescent anticoagulated whole blood sample are optically or visually analyzed in a sample chamber which has a varying through plane thickness due to convergent opposing sample chamber walls. At least one of the convergent walls of the chamber is transparent so that the blood sample constituents can be observed. The chamber's varying thickness produces a first lesser thickness region in the chamber wherein a quiescent monolayer of red blood cells in the sample will reside after the sample is introduced into and fills the chamber. Larger formed constituents such as white blood cells in the sample are unable to enter the aforesaid lesser thickness region of the chamber. The red cells which reside in the greater thickness regions will agglomerate to form rouleaux and lacunea. The exact thickness of the chamber at any particular location in the chamber can be predetermined, or can be determined in situ as the sample is being analyzed.

  • Patent number: 6197146
    Abstract: An assemblage for bonding the skin of an airfoil to the core of the airfoil includes a hybrid caul plate assembly for covering the surface of the airfoil assembly which is exposed to bonding pressure. The hybrid caul plate includes a central elastomeric component and peripheral semi-rigid metal components. The semi-rigid metal components are formed from a steel sinusoidal mesh and are axially elongated. The mesh is flexible in the direction of elongation, but are rigid in the transverse direction. The peripheral semi-rigid caul componnents will thus closely conform to the contours of the core in the axial direction, and will, at the same time, provide support for the edges of the core so that the core edges will not be crushed or deformed by bonding pressure applied to the assemblage during the skin-to-core bonding process. The result of using the hybrid caul plate assembly is an improved skin-to-core bond wherein bridging or voids in the bond line at the periphery of the airfoil are avoided.

  • Patent number: 6197523
    Abstract: A method for analyzing blood enables one to isolate, detect, enumerate and confirm under magnification the presence or absence of target cancer cells and/or hematologic progenitor cells which are known to circulate in blood. The analysis is performed in a sample of centrifuged anticoagulated whole blood. The analysis involves both morphometric and epitopic examination of the blood sample while the blood sample is disposed in a centrifuged blood sampling tube. The epitopic analysis of the presence or absence of cancer cells relies on the detection of epitopes which are known to present only on cancer cells; and the epitopic analysis of the presence or absence of hematologic progenitor cells relies on the detection of epitopes which are known to present only on hematologic progenitor cells.
