Liquid fuel from the pyrolysis reactor is provided to the combustion turbine. Liquid and gaseous fuels are provided to the boiler. Compressed oxygen from the electrolysis unit is provided to the combustion turbine. Electric power from the combustion turbine and steam turbine are provided to the electrolysis unit. The gasifier includes a preheat region, a gasification region, and a cooling region. CO2 and O2 are injected into the gasifier at multiple injection levels to create an isothermal gasification region to produce CO.

Abstract: A control system and method utilizing one or more processors that are configured to determine contaminant loading of blades of a turbomachinery compressor based on one or more environmental conditions to which the turbomachinery compressor is exposed and one or more atmospheric air inlet conditions of the turbomachinery compressor. The one or more processors then determine a corrosion contaminant concentration on the blades of the turbomachinery compressor based on the contaminant loading that is determined and determine an upper limit on or a distribution of potential corrosion of the blades of the turbomachinery based on the corrosion contaminant concentration, at least one of the environmental conditions to which the turbomachinery compressor is exposed, and the corrosion contaminant concentration that is determined.

Abstract: A system for monitoring the material changes in a structure is disclosed through the use monitoring instruments embedded within the structure. The instruments have at least one sensor with electrodes in contact with the surrounding material and electronics that are contained within the instrument. The sensor signals are converted to digital and transmitted to an external data logger or computer for display of the digitized signals. The connection between the microcontroller and the data logger can be either through hardwire or RF. Power is provided to the electronic sensors through either external or local methods. A power management system can be used to place the electronics into a sleep mode when not in use. The electronics are encapsulated within potting material within an instrument case that is manufactured from a material having a flexural modulus equal to, or greater than, the surrounding material to prevent mechanical failure of the device before failure of the surrounding material.

Abstract: Coated abrasive material having blends of abrasive grains of sol gel process alumina and alumina-zirconia in a volume ratio of at least 15% sol gel abrasive grain provide improved performance in certain grinding applications and a more universal coated abrasive product for a wider range of grinding applications than such products of either abrasive grain alone.

Abstract: This invention provides a machine for efficiently laying out biased arrays of yarns. The machine combines on a single supporting machine frame (1) two mechanically driven continuous yarn carrier strips, each provided on its edge facing the other carrier strip with a plurality of spaced yarn restrainers, and (2) a reciprocating conveyor capable of conveying a small array of spaced parallel yarns, oriented at an angle to the motion of the carrier strips between 10.degree.-80.degree., back and forth between the two carrier strips in such a manner that the yarns will be held on the restrainers at each pass of the conveyor. Continuous yarns are supplied by conventional means under constant low tension to the input of the conveyor. The relative motions of the carrier strips and the reciprocating conveyor are controlled so that the web of yarns produced is regularly patterned.

Abstract: Apparatus for the continuous sulphur drossing of lead to reduce its copper content including a plurality of reaction vessels arranged in series, each reaction vessel having a curved bottom and a stirrer for creating a vortex of the contents. Bullion and sulphur are fed into the series through a vortex at controlled rates and through the series at controlled temperatures and a controlled total reaction time, optimally between 8 and 15 minutes. The bullion, dross and unreacted sulphur, if any, are overflowed from vessel to vessel and into an unagitated vessel for separation of the dross and bullion. The bullion feed device splits the undrossed bullion into a metered stream and an unmetered stream, the unmetered stream being utilized to carry away the separated dross for further processing.
