20080271048 | Transaction Execution System Interface and Enterprise System Architecture Thereof - A system for interfacing at least one user interactive device with a trade execution system to execute trading transactions requested by users over a network includes an application in communication with the network for interfacing between the at least one user interactive device and the trade execution system and coordinating interaction of the at least one user interactive device with the trade execution system. The application contains first and second APIs. The first API is structured to deliver a trading transaction request received from the at least one user interactive device to the trade execution system. The second API is structured to deliver real-time information relating to the trading transaction request received from the trade execution system to the at least one user interactive device. The first API includes at least one stub that is called by the application at a predefined step during processing of the trading transaction request. The at least one stub includes code to interface the application with the trade execution system. | 10-30-2008 |

20150107790 | METHOD OF SEPARATION OF HEMICELLULOSE AND CELLULOSE FROM POLYSACCHARIDE SOURCES - A method of separating hemicellulose and cellulose by dissolution of hemicellulose from a hemicellulose-rich source, such as a pulp of any origin or from holocellulose. In the method, hemicellulose is dissolved in a solvent system comprising a cellulose solvent, which is either a ionic liquid or another direct cellulose solvent, and a molecular solvent (co-solvent), wherein said co-solvent does not dissolve cellulose, and wherein the solvent basicity and acidity of said ionic liquid or other direct cellulose solvent are adequately adjusted by the co-solvent. The present invention enables quantitative separation of cellulose and hemicellulose without any depolymerization and yield losses as occurring during conventional dissolving pulp manufacturing processes. | 04-23-2015 |

20160130369 | FRACTIONATION PROCESSES FOR HIGH-ASH LIGNOCELLULOSIC BIOMASS FEEDSTOCKS - A process for fractionating high-ash lignocellulosic biomass is provided, comprising: (a) providing a biomass feedstock comprising lignocellulosic material and ash, some of which may be removed before digestion; (b) contacting the feedstock with a digestor solution comprising a first organic solvent, an acid catalyst, and water, under effective digestor conditions and controlled acidity to produce intermediate solids and a first liquid phase comprising hemicelluloses and lignin; (c) separating the first liquid phase from the intermediate solids; (d) washing the intermediate solids with a wash solution comprising a second organic solvent and water, under effective washing conditions to produce cellulose-rich solids and a second liquid phase comprising hemicelluloses and lignin; and (e) separating the cellulose-rich solids from the second liquid phase. The solvent type is optimized to control acidity in the digestor. Controlling the acidity may also include adjusting digestor pH to a value between about 0.5 and about 2.0. | 05-12-2016 |

20130028279 | VERTICAL CAVITY SURFACE EMITTING LASER CAVITY WITH LOW THERMAL IMPEDANCE - The present invention concerns new designs of VCLs with high contrast gratings (HCG) combined with diamond layer as a bottom mirror. They can be realized either with a classical V-shaped pumping scenario, or through the introduction of the pumping beam from the bottom direction, through the HCG that can be designed to be transparent at the wavelength of the pumping light. They can also be completed by a HCG combined with diamond layer as top mirror, reflecting the pump diode laser and transparent to the VCL emission in the case the pumped and emitted beams are collinear. | 01-31-2013 |
