  • Publication number: 20150125378
    Abstract: A method for synthesizing catalyst beads of bulk transmission metal carbides, nitrides and phosphides is provided. The method includes providing an aqueous suspension of transition metal oxide particles in a gel forming base, dropping the suspension into an aqueous solution to form a gel bead matrix, heating the bead to remove the binder, and carburizing, nitriding or phosphiding the bead to form a transition metal carbide, nitride, or phosphide catalyst bead. The method can be tuned for control of porosity, mechanical strength, and dopant content of the beads. The produced catalyst beads are catalytically active, mechanically robust, and suitable for packed-bed reactor applications. The produced catalyst beads are suitable for biomass conversion, petrochemistry, petroleum refining, electrocatalysis, and other applications.

  • Patent number: 8849548
    Abstract: An engine system includes an exhaust system fluidly connected to an electronically controlled engine. Exhaust from the engine may travel a first pathway through a turbine of a turbocharger, or a second pathway that bypasses the turbine. An electronically controlled wastegate vale is biased to close the second pathway. An electronic controller is in communication with the electronically controlled engine and the electronically controlled wastegate valve. The electronic controller is configured to execute a wastegate diagnostic algorithm to detect a stuck closed default condition of the electronically controlled wastegate valve, and derate the engine in response to detection of a stuck closed fault condition.

  • Publication number: 20130295508
    Abstract: The present invention provides a method and apparatus for forming a printing form from a photosensitive element to form a relief pattern. The method and apparatus thermally develop the photosensitive element by heating a composition layer of the element to cause a portion of the layer to liquefy and providing a development medium to the element to remove the liquefied composition. A conformable layer is disposed between the photosensitive element and a base support, which improves the compressibility and the contact between the photosensitive element and the development medium. The method and apparatus improve the efficiency of the removal of liquefied portions from the photosensitive element and the uniformity of the relief pattern formed.

  • Patent number: 8234977
    Abstract: A materials handling apparatus for aiding in loading and transporting various materials has three major components, a wheeled cart, a truncated conical cylinder which is carried by the cart and a compaction lid which provide the apparatus with the capability of being operated in three different modes. In the first mode, a conventional trash bag is placed inside the cylinder and the lid can be placed atop the cylinder. In this mode, the apparatus operates as a conventional trash can. In a second mode, the cylinder in placed within a trash bag to protect it from being damaged by materials such as tree and shrub clippings or other materials which could tear the bag. In the third mode no trash bag is used, the materials are loaded into the cylinder, and when loading is complete, the cylinder is lifted off of the materials for direct deposit into a disposal site.
