A diagnosis and repair recommendation system for a railroad locomotive is disclosed. The system uses generalized repair recommendations and instantiates them to a specific repair process for a unique road number locomotive. In addition to repair steps to be executed by the technician, the method and system remotely provides supporting documentation specifically tailored for each step in the repair process. As the repair is being conducted, feedback information is entered by the technician. The repair recommendations and the supporting documents are available to the technician via a remote unit, thereby allowing the technician to access the repair steps and supporting documentation while the repair is in progress.

A system and process are disclosed for the controlled combustion of a wide variety of hydrocarbon feedstocks to produce thermal energy, liquid fuels, and other valuable products with little or no emissions. The hydrocarbon feeds, such as coal and biomass, are first gasified and then oxidized in a two-chamber system / process using pure oxygen rather than ambient air. A portion of the intermediate gases generated in the system / process are sent to a Fischer-Tropsch synthesis process for conversion into diesel fuel and other desired liquid hydrocarbons. The remaining intermediate gases are circulated and recycled through each of the gasification / oxidation chambers in order to maximize energy production. The energy produced through the system / process is used to generate steam and produce power through conventional steam turbine technology. In addition to the release of heat energy, the hydrocarbon fuels are oxidized to the pure product compounds of water and carbon dioxide, which are subsequently purified and marketed. The system / process minimizes environmental emissions.

A process for the manufacture of carbon disulfide comprising the following steps: (a) reacting carbon monoxide with hydrogen sulfide to form carbonyl sulfide and hydrogen; (b) contacting the carbonyl sulfide formed in step (a) with a catalyst effective for disproportionating carbonyl sulfide into carbon disulfide and carbon dioxide.

The synthesis of arrays of DNA probes sequences, polypeptides, and the like is carried out using a patterning process on an active surface of a substrate. An image is projected onto the active surface of the substrate utilizing reflective projection optics. The projection optics project a light image onto the active surface of the substrate to deprotect linker molecules thereon. A first level of bases may then be applied to the substrate, followed by development steps, and subsequent exposure of the substrate utilizing a different light image, with further repeats until the elements of a two dimensional array on the substrate surface have an appropriate base bound thereto.

A secondary button cell battery that is particularly suited for use in hearing aid appliances, and an associated charging station. Recharging is accomplished without direct conductive connection between the source of the energy and either the battery or its appliance. Radio frequency energy is harvested in an enclosed chamber in a charging station and applied to the recharging of the button cell. Such energy is harvested by the use of one or more energy harvesting diodes connected in parallel with the battery. Multiple diodes connected in parallel or serial may be used to adjust charging current or voltage or both. Charge control is provided by directly or indirectly detecting the level of charge on the cell. Where the associated appliance is a hearing aid, the charge level detection may be accomplished acoustically by determining the characteristics of the sound emitted by the hearing aid, and charging is accomplished with the cell within the hearing aid appliance.

An arrangement for detachably fixing a guide blade segment that forms part of a transition channel of an aircraft gas turbine comprises high-pressure and low-pressure turbines. The arrangement has a groove-hook-type connection in the front area of the outer platform of the guide blade segment for its radial fixation and at least one pin that penetrates the hook-groove-type connection for securing it against rotation of the guide blade segment.
