20130292299 | INTEGRATED EBULLATED-BED PROCESS FOR WHOLE CRUDE OIL UPGRADING - A system and process for upgrading a whole crude oil feed in an integrated ebullated-bed and hydrotreater is provided in which the whole crude oil is flashed into a flashed straight run distillates fraction and an atmospheric residue fraction. The atmospheric residue fraction is hydroprocessed in an ebullated-bed reaction zone, while the flashed straight run distillates fraction and the products fraction produced from the ebullated-bed reaction zone are hydrotreated in a fixed-bed reaction zone. Distillates from the hydrotreater and the unconverted residue fraction from the ebullated-bed reaction zone can be combined to produce an upgraded synthetic crude oil. | 11-07-2013 |

20120173133 | METHOD FOR ESTIMATING THE HEIGHT OF THE GRAVITY CENTER OF A VEHICLE - A method is provided for estimating the height of the gravity center of a vehicle having at least a front axle and a rear axle each carrying at least two wheels. The method includes determining a first braking period and a second braking period occurring along road portions having substantially the same slope, but where the first and second braking periods result in different vehicle decelerations, and during both braking periods, estimating at least the following variables: vehicle acceleration; the wheel slippage rate for the front and rear axles; the braking forces or braking torque at each of the front and rear axles, or a ratio thereof; and the slope of the corresponding road portion. The method also includes estimating, using only the foregoing estimations made during both periods, the vehicle center of gravity height. | 07-05-2012 |

20130025244 | SELECTIVE GAS FILTER - A filter including multiple tanks connected in series by connecting ducts. In the filter a flow of gaseous flows encounters multiple obstacles in it, an effect of which is efficiently to block constituents with heaviest molecular weight, without substantially hindering diffusion of lighter constituents. This may be obtained by internal baffles, or by a bank of finer ducts, for example at an inlet of the filter. Such a filter may find application to separation of hydrogen and radon produced by nuclear waste. | 01-31-2013 |
