| 20090252637 | JOINING OF DIFFICULT-TO-WELD MATERIALS AND SINTERING OF POWDERS USING A LOW-TEMPERATURE VAPORIZATION MATERIAL - The present invention discloses a process for sintering particles using a sintering aid. The sintering aid can be brought into contact with a plurality of particles to be sintered such that a mixture of the particles and the sintering aid is provided. The mixture of particles and the sintering aid is heated and at least part of the sintering aid is vaporized. Sintering of the particles to form a sintered component followed by cooling of the sintered component can complete the process, or in the alternative, a subsequent heating step or steps can be included whereby additional vaporization of the sintering aid can occur. | 10-08-2009 |
| 20100038325 | METHOD AND APPARATUS FOR IMPROVING WATER QUALITY BY MEANS OF GASIFICATION - A method and apparatus are provided for improving water quality using a gasification system. Whereas water is normally a deterrent to the combustion process, water is beneficial to the gasification of carbonaceous materials. The method and apparatus uses this, and other aspects, to utilize several processes to improve water quality by means of gasification in new and beneficial ways. | 02-18-2010 |
| 20100312028 | MULTIPRODUCT BIOREFINERY FOR SYNTHESIS OF FUEL COMPONENTS AND CHEMICALS FROM LIGNOCELLULOSICS VIA LEVULINATE CONDENSATIONS - An integrated method for production of liquid transportation fuels, fuel additives, or chemicals in a biorefinery by the conversion of cellulosic materials is disclosed herein. The method is based on converting a source of C6 sugar such as cellulosic materials and sugars into a mixture of hydrotreated compounds. The biorefinery operates in a unique parallel-processing mode, wherein the initial biomass feedstocks are disassembled to provide substrates for parallel branches whose products may be reassembled in either a condensation step or a mixed hydrotreating step or a final fuel-blending step. The cellulosic materials can be converted to levulinate intermediates that condense with intermediates derived from other processes to produce fuels with the appropriate range of sizes in the target molecular composition, thus generating desirable combustion and physical properties. This method also makes use of methyltetrahydrofuran and other low carbon by-products that are separated for use as amphiphilic solvents. In an embodiment, the method produces cyclic ethers via mild hydrotreating of the condensation products, or long-chain keto ester, useful for plasticizers, by condensing a portion of the levulinate with a reagent containing an unsaturated group. In another embodiment, the method produces a ketal by converting a portion of the condensation product in an acid-catalyzed reaction with a diol. | 12-09-2010 |
| 20110061290 | AVIATION-GRADE KEROSENE FROM INDEPENDENTLY PRODUCED BLENDSTOCKS - Aviation-grade kerosene comprising a first blendstock derived from non-petroleum feedstock and comprising primarily hydrocarbons selected from the group consisting of isoparaffins and normal paraffins, and a second blendstock comprising primarily hydrocarbons selected from the group consisting of cycloalkanes and aromatics. | 03-17-2011 |

| 20110071026 | LOW VISCOSITY, AQUEOUS GLYPHOSATE SALT CONCENTRATES - The present invention provides a low viscosity, aqueous concentrate comprising a primary amine salt of glyphosate and surfactant. The aqueous concentrate can be formed from a highly concentrated glyphosate composition that has very low levels of glyphosate in non-salt form. Exemplary aqueous concentrates include a primary amine salt of glyphosate in the range of 45 percent weight to 68 percent weight, and a surfactant at a concentration in the range of 3 percent weight to 27 percent weight, with the concentrate having a viscosity in the range of 40 to 450 centistokes. | 03-24-2011 |
| 20110071027 | HIGH STRENGTH AQUEOUS GLYPHOSATE SALT CONCENTRATES AND METHODS - The present invention provides a high-strength glyphosate salt aqueous concentrate and a method for forming the concentrate. The method uses high purity and low water content glyphosate acid and primary amine preparations. The glyphosate acid and primary amine are reacted in the presence of a nominal amount of water. The method provides a concentrate with a very high concentration of biologically effective glyphosate salt, and a minimal amount of biologically ineffective glyphosate acid particulates. The minimal amount of particulates improves the viscosity of the concentrate to commercially acceptable levels, and the beneficial properties associated with the concentrate can be carried over into excipient-containing concentrates and application compositions that are formed from the high-strength glyphosate salt aqueous concentrate. | 03-24-2011 |
| 20110219686 | PLANT GROWTH REGULATOR COMPOSITIONS AND METHODS - Described are compositions and methods for regulating plant growth that use a complex of an imidazolinone ion and a metal counterion; the compositions and methods include methods of regulation plant growth, optionally in combination with herbicidal, fungicidal, and fertilizer compositions and effects. | 09-15-2011 |
