  • Patent number: 8962294
    Abstract: An acetyl xylan esterase variant having perhydrolytic activity is provided for producing peroxycarboxylic acids from carboxylic acid esters and a source of peroxygen. More specifically, a Thermotoga maritima acetyl xylan esterase gene was modified using error-prone PCR and site-directed mutagenesis to create an enzyme catalyst characterized by an increase in specific activity. The variant acetyl xylan esterase may be used to produce peroxycarboxylic acids suitable for use in a variety of applications such as cleaning, disinfecting, sanitizing, bleaching, wood pulp processing, and paper pulp processing applications.

  • Patent number: 8965549
    Abstract: A method for continuous production planning includes identifying a forbidden transition associated with production of first and second end products. The forbidden transition indicates that a manufacturer should not produce the first and second end products consecutively. The method also includes identifying a bridge product associated with the forbidden transition. The bridge product represents a product that the manufacturer could produce between production of the first and second end products. The method further includes determining a quantity of the bridge product that could be produced by the manufacturer. In addition, the method includes scheduling production of the first and second end products and the bridge product.

  • Patent number: 8959903
    Abstract: A reductant delivery system is provided for delivery of reductant to an engine exhaust aftertreatment system that is heated during cold temperature conditions. A heat exchange fluid flows through a heat exchange circuit that provides a flow path from the heat source to the doser, from the doser to the reductant storage tank, and from the reductant storage tank to the heat source. A control valve controls the flow of the heat exchange fluid in the heat exchange circuit so that at least one heat exchange cycle includes a circulation period that increases the temperature of the reductant in the doser and storage tank and a termination period where circulation is stopped until reductant temperature in the doser reaches a lower limit.

  • Patent number: 8961348
    Abstract: A drive axle housing system may minimize churning of splash and spray oil within a drive axle housing. The drive axle housing system includes apparatus for incorporation into the axle, the apparatus including an oil churning reduction member that may be affixed to the interior walls of the axle housing. The oil churning reduction member includes interior surfaces adapted to closely align with interior moving gear components of the axle to minimize efficiency losses due to oil movement. The system may also incorporate an annular element, affixed to the axle housing and closely aligned with the backside of a ring gear component of the differential axle. The combined use of the member and the element may substantially reduce torque losses attributable to excessive churning of oil.

  • Patent number: 8961771
    Abstract: Processes and systems for electrolytically processing a microfeature workpiece with a first processing fluid and an anode are described. Microfeature workpieces are electrolytically processed using a first processing fluid, an anode, a second processing fluid, and a cation permeable barrier layer. The cation permeable barrier layer separates the first processing fluid from the second processing fluid while allowing certain cationic species to transfer between the two fluids. The described processes produce deposits over repeated plating cycles that exhibit deposit properties (e.g., resistivity) within desired ranges.

  • Patent number: 8960843
    Abstract: What is disclosed is a multi-function inkjet print system which prints with inks having thermo-reactive properties and which can further process media printed with thermo-reactive inks such that the various properties of the inks can be activated. One embodiment of the present print device comprises at least one thermo-changing element which resides in proximity to a transport path along which the media travels. The thermo-changing element effectively changing a temperature T of the media to: T?TL or T?TH, as desired. In various embodiments, a sensor is used for sensing a temperature of the media. A temp-normalizing element is positioned along the transport path and downstream of the thermo-changing element for changing a temperature of the media such that the media's temperature T can be normalized back to a range of TL<<T<<TH prior to the media being deposited into an output tray. Various embodiments of a user interface are disclosed.
