  • Potential-based asset comparison
    Patent number: 8306891
    Abstract: Measurements for comparing one financial asset to another are provided. For example, in one aspect a comparison measurement is generated between a model estimate and an observed market value for an asset and then such comparison measurements are compared for two different assets. In another aspect, tracking error and performance differences between two assets are measured simultaneously, thereby providing better isolation of important information.

    Publication number: 20120211580
    Abstract: A pipe inspection system may include a cable storage drum and a length of resilient flexible push-cable. An asymmetric bearing device supports the cable storage drum for rotation about the rotational axis in a pay-out direction and an opposite pay-in direction. In one embodiment, the asymmetric bearing device automatically decreases, without the for manual adjustment, an amount of friction exerted against rotation of the cable storage drum upon reversal of the direction of rotation of the cable storage drum from the pay-out direction to the pay-in direction.

  • Stable sub-micron titania sols
    Patent number: 8247343
    Abstract: The present invention is directed to compositions and processes for the production of stable, alkaline, high solids, low viscosity, low surface tension, low flammability, sub-micron titania sols that have minimal offensive odor and methods of their use. Compositions of the present invention include, for example, mixtures of strong and weak organic bases used as dispersants to stabilize the titania sols. The dispersant mixtures have been found to result in relatively high titania solids content, low surface tension, low viscosity suspensions that are low in flammability. Sols produced according to the present invention can be used, for example, in catalytic applications such as catalyst supports for diesel emission control, or in pollutant photocatalyst applications in which it is desirable to have the titania in sol form.

  • Sensitivity/elasticity-based asset evaluation and screening
    Patent number: 8249970
    Abstract: Provided is a technique for evaluating an asset, such as a share of stock in a corporation, by processing historical data for value of an asset and historical data values for various exogenous variables to obtain a formula for calculating a measure of a tendency of the value of the asset to change as a result of changes in the data values for the exogenous variables, the formula being a function of the exogenous variables. Projected data values are then obtained for the exogenous variables, and a measure of the tendency of the value of the asset to change based on a change in at least one of the exogenous variables is estimated using the formula and the input projected data values.

  • SILICA-STABILIZED ULTRAFINE ANATASE TITANIA, VANADIA CATALYSTS, AND METHODS OF PRODUCTION THEREOF
    Publication number: 20110027154
    Abstract: The invention is directed to compositions and processes for the production of silica-stabilized ultrafine anatase titanias and which may further comprise tungsten and vanadia. The surface stabilization may be by treatment of the TiO2 particles with a low molecular weight and/or small nanoparticle form of silica such as, in preferred embodiments, a tetra(alkyl)ammonium silicate or silicic acid, which serves to efficiently maintain the anatase phase and prevent crystal growth under severe thermal and hydrothermal conditions, even in the presence of vanadia. The vanadia catalysts produced from the novel titanias have equal or improved catalytic activity for selective catalytic reduction of NOx compared to conventional vanadia supported silica-titania based catalysts. The invention is further directed to diesel emission catalytic devices comprising the novel titania-based catalyst compositions.
