20110065846 | Olefin polymerisation process - A process for producing an olefin polymer in a slurry polymerisation process is disclosed, in which the process is operating at a temperature of 90° C. to 107° C. and utilising a chromium catalyst having an activity of at least 1,000 g polymer/g catalyst/hour on a support having a pore volume of at least 1.3 cm | 03-17-2011 |
20120094049 | TALC AS A FIRE PERFORMANCE MODIFIER IN POLYMER COMPOSITIONS - The use of talc as a fire performance modifier in polymer compositions is disclosed, in which the talc is present in an amount less than 30 percent by weight of the total weight of the polymer composition, and also in amounts ranging from 5 to 30 percent by weight of the polymer composition. In such polymer compositions, the impact performance of the composition is not compromised, the composition, for example, being useful in manufacture of plastic and polymer based pallets for storage and for warehouse use. Talc is disclosed to act as a fire performance modifier and char agent at concentrations as low as 5 weight percent in polymer compositions by modifying the Heat Release Rate shown by, first, lowering the Peak Heat Release, and second, by shortening the time period to reach the Peak Heat Release compared to the virgin polymer resin. | 04-19-2012 |

20120179439 | System and Method of Hydrocarbon Formation Modeling - Hydrocarbon formation modeling. At least some of the illustrative embodiments are methods including simulating reaction of the formation to hydrocarbon extraction over a plurality of time steps. With each time step, the illustrative method makes a first approximation of migration of saturations for at least one grid block of the plurality of grid blocks (wherein migration of the saturation within at least one time step spans more than one grid block), and then correct the first approximation of migration of saturations for an effect not considered in the first approximation. | 07-12-2012 |

20140032193 | VARIABLE FIDELITY SIMULATION OF FLOW IN POROUS MEDIA - A fine computer model covering an area includes a fine grid. A fault follows a fine-grid-path. The fault divides the area into a first fine side and a second fine. A model of a source of fluid flow is on the first fine side of the area. A model of a sink of fluid flow is on the second fine side of the area. The computer coarsens the model. The fault follows a coarse-grid-path in the coarsened model. The coarse-grid-path divides the area into a first coarse side and a second coarse side. The model of the source and the model of the sink are on the first coarse side of the area. One of the source or the sink is moved to the second coarse side of the area. | 01-30-2014 |
20140350906 | System and Method for Simulation of Gas Desorption in a Reservoir Using a Multi-Porosity Approach - A hydrocarbon shale reservoir simulation system and method represented by a model having at least four different types of porosity nodes is described. The method includes the computer-implemented steps of characterizing porosity nodes within the model as one of natural fracture pore systems, matrix pore systems, induced fracture pore systems or vug pore systems. Following characterization, transfer terms between nodes are identified. Transfer terms may include transfer terms between vug nodes, matrix nodes, natural fracture nodes and induced fracture nodes. Once transfer terms have been assigned, the linear system for the model can be solved utilizing a linear solver. The method further includes the steps of utilizing the characterized pore nodes to define one or more subgrids that represent a zone within the reservoir, wherein the zone includes at least one node of each porosity type; and wherein the linear solver is applied by subgrid or associated sub-grids. | 11-27-2014 |

20090015549 | Accepting User Input - The invention is directed to an improvement in mechanisms and techniques for accepting user input. An apparatus for accepting a user input is described comprising a display, and a plate and a control knob positioned over the display. A portion of the display is visible through the plate, and a portion of the control knob is optically transparent such that information displayed by the display is visible through the control knob. In some examples, the control knob functions as both a rotary input and as a push button input. The control knob may function as a push button input through a transfer of force through the plate to a pressure sensing switch associated with the plate. The control knob may function as a rotary control through drive gears, belts, or interaction with a light emitter and detector. | 01-15-2009 |
20100109687 | Impedance Measurement System and Method - The impedance of ionic solutions may be determined using a bridge circuit where the ionic solution comprises a leg of the bridge circuit and a reference impedance characterized by a reference time constant comprises a second leg of the bridge circuit. The bridge is driven by a switched DC voltage waveform. Measurement of the ionic solution is delayed after switching to allow the reference impedance to reach its asymptotic value. The reference impedance may be varied to reduce the reference time constant. | 05-06-2010 |
