  • Publication number: 20130331259
    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.

    Abstract: A pipe guide includes a pair of cylindrical shells each having a plurality of radially extending circumferentially spaced vanes and structure for holding the shells together when the shells are axially mated end-to-end. A pair of curved tab arms extend circumferentially about corresponding ones of the cylindrical shells.

  • Patent number: 8521663
    Abstract: The value of a target variable is predicted by obtaining historical values for the target variable at each of several time points and obtaining previously predicted values and currently predicted values for each of several predictor variables, the predictor variables being different from the target variable. Values are assigned to parameters of a forecasting model to obtain the best fit of the previously predicted values for the predictor variables to the historical values for the target variable. Finally, a value of the target variable is predicted from the currently predicted values for at least a subset of the predictor variables using the forecasting model and the values assigned to the parameters of the forecasting model.

  • Publication number: 20130206124
    Abstract: An apparatus includes an internal combustion engine with an engine block and a cylinder liner housing a piston. The engine block includes at least one cylinder cavity and at least one replaceable cylinder liner positioned within the cylinder cavity. At least two press fit areas create an interference fit between the engine block and the replaceable cylinder liner. One press fit area is located proximate to the top surface of the engine block and the other press fit area is located in the engine block at the opposite end of the cylinder liner. A storage volume is formed between the press fit areas by the outer surface of the cylinder liner and the surface of the engine block defining the cylinder cavity.

  • Patent number: 8507405
    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.

  • Patent number: 8496204
    Abstract: The actuator locking mechanism is a bi-directional secondary load path lock that operates under both compression and tension loads via a radial locking wedge and axial slide lock system. This locking mechanism is designed to effectively protect against structural disconnect after a primary load path failure occurs and to minimize the axial play in the engaged secondary load path. To avoid the dormancy of such a failure, the activated mechanism jams/stalls the actuator drive thereby alerting the aircrew and the maintenance crew of the fault condition and allowing safe continued flight and landing. This locking mechanism is impervious to relative deflection between the primary and secondary load path such that under a non-failed condition, the mechanism will not jam. A jam only occurs when axial displacement (tension or compression direction) is greater than a predetermined relative deflection. This axial displacement is eliminated by the slide locking system minimizing the axial play.

  • Patent number: 8494940
    Abstract: New metrics are provided for evaluating a portfolio of financial assets and/or for determining whether or not the portfolio is properly tracking the performance of a desired index. The technique involves calculating a correlative value for the portfolio relative to each of a number of different factors having data values that are likely to be correlated with an aggregate market value for the portfolio, where the correlative value for an item relative to a given factor is a measure of a tendency of the aggregate market value of the item to change based on a change in the data value for such factor (e.g., in the nature of a sensitivity or elasticity). Such metrics often can be used, according to the present invention, in conjunction with other information to facilitate the adjustment of the portfolio to more closely track the performance of the desired index.

  • Patent number: 8481453
    Abstract: An apparatus and method for treating diesel exhaust gases are described. The system consists of two functionalities, the first being a selective catalytic reduction (SCR) catalyst system and the second being a capture material for capturing catalyst components such as vanadia that have appreciable volatility under extreme exposure conditions. The SCR catalyst component is typically based on a majority phase of titania, with added minority-phase catalyst components comprising of one or more of the oxides of vanadium, silicon, tungsten, molybdenum, iron, cerium, phosphorous, copper and/or manganese vanadia. The capture material typically comprises a majority phase of high surface area oxides such as silica-stabilized titania, alumina, or stabilized alumina, for example.

  • Patent number: 8333162
    Abstract: A marine deck structure for rope contact having an impermeable cover for the purpose of preventing chaffing and wear of ropes is disclosed. Provided is a marine deck structure, such as a bullnose, or H-Bit covered with a durable impermeable cover that protects the structure from the harsh elements and provides a smooth low abrading surface. In another embodiment, rope chaffing surfaces on a marine vessel or dock are covered with an impermeable cover to reduce rope wear. The impermeable cover in one embodiment comprises ultra high molecular weight polyethylene (UHMWPE).

  • 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.
