20150191612 | ANTI-CRACKING AGENT FOR WATER-BORNE ACRYLIC PAINT AND COATING COMPOSITIONS - This invention relates to water-borne acrylic paints and coatings, especially to agents that can be used to reduce the amount of VOCs to yield satisfactory paints or coatings. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to accomplish a reduction in VOCs and at the same time increase hardness and lower cracking of the dried acrylic paints and coatings. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. | 07-09-2015 |
20150203737 | PLANT DERIVED CELLULOSE COMPOSITIONS FOR USE AS DRILLING MUDS - This invention relates to water-based well drilling fluids. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to produce suspensions having viscosity and rheological properties particularly suitable for use as a drilling fluid. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. Breaking plant-based pulp down into this kind of cellulose based particles involves fewer and gentler processes than to break the pulp down further into cellulose nanofibrils, and therefore the present cellulose based particles can be produced much faster and at lower cost than completely unraveled cellulose nanofibrils. The well drilling fluids based on the cellulose material of this invention are stable over a wide range of operating temperatures. | 07-23-2015 |
20150210967 | STRUCTURING AGENT FOR LIQUID DETERGENT AND PERSONAL CARE PRODUCTS - This invention relates to an external structuring agent for application in liquid detergent and personal care products. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can advantageously be used to structure liquid detergent and personal care products, providing certain benefits that are much sought after in the design of such products. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. The process of making the structuring agent involves processing under relatively mild conditions, of a biological material that is currently considered a by-product. | 07-30-2015 |

20110126546 | METHOD FOR SWITCHING OVER A GAS TURBINE PLANT FROM GASEOUS FUEL TO LIQUID FUEL AND VICE-VERSA - In a method for switching over a gas turbine plant from gaseous fuel ( | 06-02-2011 |
20120247116 | METHOD FOR SWITCHING OVER A GAS TURBINE BURNER OPERATION FROM LIQUID TO GAS FUEL AND VICE-VERSA - A method is provided for switching over a gas turbine burner operation from liquid fuel to gas fuel and vice-versa, with the burner comprising nozzles for feeding a premixed gas fuel, nozzles for injecting a pilot gas fuel and nozzles for injecting a liquid fuel. According to the method, while the liquid fuel and the premix gas fuel are regulated to switch over from liquid fuel to gas fuel operation or vice-versa, the pilot gas fuel is controlled at a substantially constant flow rate. | 10-04-2012 |
20120260665 | REHEAT COMBUSTOR FOR A GAS TURBINE ENGINE - A reheat combustor for a gas turbine engine includes a fuel/gas mixer for mixing fuel, air and combustion gases produced by a primary combustor and expanded through a high pressure turbine. Fuel injectors inject fuel into the mixer together with spent cooling air previously used for convectively cooling the reheat combustor. The fuel mixture is burnt in an annular reheat combustion chamber prior to expansion through low pressure turbine inlet guide vanes. The fuel/gas mixer and optionally the combustion chamber define cooling paths through which cooling air flows to convectively cool their walls. The fuel injectors are also convectively cooled by the cooling air after it has passed through the fuel/gas mixer cooling paths. The low pressure turbine inlet guide vanes may also define convective cooling paths in series with the combustion chamber cooling paths. | 10-18-2012 |

20150040573 | GAS TURBINE WITH IMPROVED PART LOAD EMISSIONS BEHAVIOR - In a method for the low-CO emissions part load operation of a gas turbine with sequential combustion, the opening of the row of variable compressor inlet guide vanes is controlled depending on the temperatures of the operative burners of the second combustor and simultaneously the number of operative burners is kept at a minimum. This leads to low CO emissions at partial load of the gas turbine. | 02-12-2015 |
20150052904 | METHOD FOR CONTROLLING A GAS TURBINE GROUP - The invention relates to a method for controlling a gas turbine group including, a first combustion chamber, a first turbine connected, a second combustion chamber, a second turbine, and a load. The method includes: measuring a temperature TAT1 at an outlet of the first turbine; determining a ratio S1R of a fuel mass flow feeding a pilot flame of the first combustion chamber to a total fuel mass flow feeding the first combustion chamber based upon the measured temperature TAT1 in accordance with a predetermined mapping table between ratio S1R and temperature TAT1; adopting the larger one between the determined ratio S1R and a predetermined booster ratio S1R to be used in the controlling fuel flow feeding the first combustion chamber of the gas turbine group. Pulsation behavior of the gas turbine group may be improved. High pulsation during fast de-loading of the gas turbine group is substantially is decreased, avoiding potential damage to the parts of the gas turbine group. | 02-26-2015 |
