Abstract: The process for stator bar rewinds includes disassembly of the stator bars at the generator site, measurement of the stator bars, forwarding digital representations of the measurements to a manufacturing center and forming 3-Dimensional models of the stator bars requiring replacement and the stator. The stator bar 3D model is placed in the stator 3D model to insure accuracy of fit. Tooling and stator bar drawings are generated and sample stator bars are manufactured. 3D modeling of the manufactured sample stator bars are compared to the nominal 3D models to insure accuracy. The replacement stator bars are manufactured and forwarded in batches for assembly into the extant generator.

Abstract: Novel one part, heat cured pressure-sensitive adhesives capable of bonding metallic and non-metallic materials at ambient temperatures and curing at elevated temperatures to form a bond with very high adhesive bond strengths at temperatures up to at least 160° C. The invention is particularly well suited for use with insulated copper coils in electrical generators and includes both the adhesive compositions per se and adhesive transfer tapes capable of bonding to the copper coils at ambient temperatures upon contact due to the pressure sensitive tack of the adhesive. The transfer tapes can subsequently be cured to a hard, thermoset adhesive with high adhesive bond strength. In applications on insulated copper coils, exemplary one part, heat cured pressure-sensitive adhesives can be used either alone or in combination with a substrate to form single or double-sided adhesive tape capable of securing the generator rotor turn insulation.

Abstract: The present invention comprises a method for anaerobic remediation of contaminated soil and groundwater comprising (a) preparing an aqueous mixture of a sparingly soluble digestible fat or oil, (b) heating and homogenizing such mixture until a stable emulsion having a particle size below 1 micron is obtained, and (c) injecting such under anaerobic conditions into the contaminated soil. The heating is preferably conducted at pasteurization temperatures and the homogenization is preferably conducted in a food homogenizer. This invention also relates to the fine emulsions formed in the homogenization and pasteurization process and to the soil that has been treated by the inventive remediation method. The emulsion is preferably combined with a water soluble, rapidly biodegradable microbial food compound and can also be combined with microbes useful in the remediation process.

Abstract: The invention provides methods of using dihydroxy unsaturated fatty acids as markers for identifying patients with a disorder associated with abnormal regulation of the cytochrome P450 metabolism or oxidation of unsaturated fatty acids. In preferred embodiments, linoleic acid diols, including, but not limited to, leukotoxindiol, are used as a diagnostic tool for identifying patients with pre-eclampsia, eclampsia, and pregnancy-induced hypertension.

Abstract: The present invention provides a system and method of bioremediation by mixing a gas and in particular a high oxygen content low pressure gaseous stream with water at a higher pressure, dissolving the gas in the water at elevated pressures by subdividing the water into fine droplets and thereafter injecting such water into soil containing contaminated groundwater.

Abstract: An airblast fuel injector assembly for use in conjunction with a gas turbine is disclosed which includes an elongated tubular body having first and second concentric tubes separated from one another by a helical spacer wire so as to define a fuel passage therebetween. The injector assembly is situated such that fuel flow exiting the fuel passage is intersected by an air flow at a predetermined angle of incidence so as to atomize the fuel flow.

Abstract: A method and apparatus for applying morphological image criteria that identify image units in an undecoded document image having significant information content, and for retrieving related data that supplements the document either from elsewhere within the document or a source external to the document. The retrieved data can result from character code recognition or template matching of the identified significant image units, or the retrieved data can result directly from an analysis of the morphological image characteristics of the identified significant image units. A reading machine can allow a user to browse and select documents or segments thereof, and to obtain interactive retrieval of documents and supplemental data.

Abstract: Organic contaminants are removed from water by microbial biodegradation in a stirred tank system having a powdered or granular media for biofilm support. A stirring impeller maintains the media suspension, provides a shear force to remove excess biomass from media particles and is adjustable to provide an optimal biofilm thickness.

Abstract: The present invention provides for an angle iron cover to be removably secured to an angle iron. This angle iron cover includes a first wall, a second wall and a securing mechanism for securing the cover to the angle iron. This design and configuration of the angle iron cover will provide for an aesthetically pleasing view in areas where openings are located in brick buildings and will also shield any rusting that can occur with the angle iron from the view of sight.

The received power voltage is boosted to a level no lower than a preselected level above battery voltage and regulated so that a constant charging current is supplied to a battery under charge in each of several charging modes. The charger has controls which are responsive to various battery parameters and circuitry to initiate various safety signals. The constant charging current is supplied by a buck regulator which has MOSFET transistors connected to form a current regulating loop.

Abstract: A battery charger receives electrical power from an external source of direct current electrical power. The power is received through a first inductor which supplies it to a second node. First switching means receives the power from the second node and supplies it to a third node. A second inductor receives the power from the third node and supplies it to the battery to be charged through output connector means. Second switching means are connected to the second node and to a capacitor which is connected to the third node so that the second switching means can switch the capacitor between series circuit and parallel circuit configurations with respect to the first and second inductors. A safety circuit is connected to temperature sensing means positioned to sense the temperature of the battery to be charged, to the first node and to the first switching means. The safety circuit causes the first switching means to become nonconductive upon detection of unsafe conditions which may occur when charging.
