Abstract:
A sulfur scrubbing method and structure is operable to remove substantially all of the sulfur present in an undiluted oxygenated hydrocarbon fuel stock supply which can be used to power an internal combustion engine or a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The fuel stock can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, thiophenes, and the like. The undiluted hydrocarbon fuel supply is passed through a desulfurizer bed which is provided with a high surface area nickel reactant, and wherein essentially all of the nickel reactant in the scrubber bed reacts with sulfur in the fuel stream, so as to remove sulfur from the fuel stream by converting it to nickel sulfide on the scrubber bed. The desulfurized organic remnants of the fuel stream continue through the remainder of the fuel processing system in the fuel cell power plant, or through the internal combustion engine. The desulfurizer bed is preferably formed from a high surface area ceramic foam monolith, the pores of which are coated with the high surface area nickel reactant. The use of the foam monolith combined with the high surface area of the reactant, enables essentially 100% of the nickel reactant to come into contact with the fuel stream being desulfurized. The scrubber bed can also be formed from high surface area nickel coated alumina pellets, from a high surface area nickel coated ceramic extrusion, from high surface area nickel pellets, and from high surface area nickel extrudates.

Abstract:
A fuel system for a propulsion system includes a fuel deoxygenating device and a catalytic module containing catalytic materials. The fuel deoxygenating device removes dissolved oxygen from the fuel to prevent formation of insoluble materials that can potentially foul the catalyst and block desirable catalytic reactions that increase the usable cooling capacity of an endothermic fuel.
Abstract:
A cooling system for a gas turbine engine includes a fuel deoxygenator for increasing the cooling capacity of the fuel. The fuel deoxygenator removes dissolved gases from the fuel to prevent the formation of insoluble deposits. The prevention of insoluble deposits increases the usable cooling capacity of the fuel. The increased cooling capacity of the deoxygenated fuel provides a greater heat sink for cooling air used to protect engine components. The improved cooling capacity of the cooling air provides for increased engine operating temperatures that improves overall engine efficiency.
Abstract:
A device and method for performing a rapid immunoassay for a biological analyte containing a positive control analyte which is concurrently tested using the same device and immunochemical reaction as the biological analyte. The positive control analyte is non-crossreactive with the biological analyte to be detected and may be an immunogen or a hapten. The device and method permit operators of the test device, particularly non-laboratory professionals, to determine that an assay is performed correctly and that the device is functioning properly, thereby allowing the operator to have confidence in the accuracy of either a positive or negative result. This is particularly important when a positive result is indicated by the absence of color at a test site, which is counterintuitive with many operators and which frequently occurs with a competitive immunoassay.
Abstract:
A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted oxygenated hydrocarbon fuel stock supply which contains an oxygenate and which is used to power an internal combustion engine in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The fuel stock can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the desulfurized organic remnants continue through the remainder of the fuel processing system. The method can be used to desulfurize either a liquid or a gaseous fuel stream, which contains an oxygenate such as MTBE, ethanol, methanol, or the like. The inclusion of the oxygenate serves to extend the useful life of the desulfurization apparatus and method.

Abstract:
An improved magnetic read/write head actuator assembly for use within a storage disk system that provides reduced average access time. The actuator assembly includes an actuator arm mounted on a pivotal E-block structure. A read/write head is supported at a distal end of the actuator arm such that the head is positioned in close proximity to a rotating magnetic storage disk. An actuator motor cooperates with the E-block structure to provide pivotal motion to the actuator arm about a central pivot axis. The actuator motor includes a pair of rotor windings connected to the E-block structure at an end opposite the actuator arm and stator magnet structure that is statically mounted in close proximity to the rotor windings. The actuator motor further includes a flux conductive member for forming a closed magnetic flux path through the windings and the stator magnets. The pair of rotor winding are oriented in a plane normal to the plane defined by the pivotal angular motion of the actuator assembly. The geometry of the actuator motor windings together with their orientation generates an increased magnetic torque vector force. This increased torque vector force generated by the windings is transposed to the E-block structure for increasing the pivotal speed of the actuator arm about the central pivot axis with no increase in power consumption.
