  • Patent number: 7638057
    Abstract: A process for treating water containing dissolved organics, for example, oil sands process-affected water, using petroleum coke is provided, comprising: removing petroleum coke from a coking operation; forming a petroleum coke/water slurry by adding the water to be treated to the petroleum coke; and mixing the slurry for a sufficient time in a carbon adsorption reactor to allow the petroleum coke to adsorb a substantial portion of the dissolved organics from the water.

  • Publication number: 20090270128
    Abstract: A communication apparatus is provided. A first subscriber identity card camps on a first cell belonging to a first wireless network via a radio transceiver module and stores first contact entries each having a destination address. A second subscriber identity card camps on a second cell belonging to a second wireless network via the radio transceiver module and stores second contact entries each having a destination address. A processor receives an apparatus originated communication request with a destination address, determines whether the received destination address is currently stored in one of the first contact entries of the first subscriber identity card or one of the second contact entries of the second subscriber identity card, and transmits the apparatus originated communication request to the cell that the determined subscriber identity card camps on to establish a wireless communication with a peer device associated with the received destination address.

  • Publication number: 20090259974
    Abstract: A display method for displaying content menus for use in a mobile device is disclosed. The method comprises the following steps. First, a user request is received. Second, display brief of actual data is acquired from an entry of an index file of a non-volatile storage medium according to the user request. Thereafter, a content menu comprising a menu item with the display brief is generated. Then, the generated content menu is displayed, wherein the entry further comprises information pointing to a location which the actual data stores in the non-volatile storage medium, the display brief is a reduced form of the actual data, and the actual data is displayed when the menu item is selected.

  • Publication number: 20090239582
    Abstract: A communication apparatus is provided. The communication apparatus includes at least one radio transceiver module, a first subscriber identity card, a second subscriber identity card and a processor. The first subscriber identity card camps on a first cell belonging to a first wireless network via the same or different radio transceiver modules. The second subscriber identity card camps on a second cell belonging to a second wireless network via the same or different radio transceiver modules. The processor, coupled to the first subscriber identity card, the second subscriber identity card and the radio transceiver module(s), receives an apparatus originated communication request with a destination address, compares a signal strength of a first signal received from the first cell with a signal strength of a second signal received from the second cell and establishes a wireless communication with a peer device having the destination address through the cell with better signal strength.

  • Publication number: 20090239584
    Abstract: A method for transmitting mobile originated requests by a mobile station with a first subscriber identity card and a second subscriber identity card, executed by a processor, is provided. It is determined whether a preference setting has been enabled. A preferred subscriber identity card is obtained from the first subscriber identity card and the second subscriber identity card when the preference setting has been enabled. The mobile originated request is issued to a called party via the preferred subscriber identity card when the preference setting has been enabled.

  • Publication number: 20090152237
    Abstract: A ceramic-copper foil bonding method includes wet-oxidizing a copper foil such that a surface of the copper foil is oxidized to a copper oxide layer, contacting the copper oxide layer with a surface of a ceramic substrate, and bonding the copper oxide layer of the copper foil to the surface of the ceramic substrate by heat treatment. Preferably, a protective layer is provided on an opposite surface of the copper foil so that the opposite surface is not oxidized during wet-oxidizing the copper foil.

  • Publication number: 20080261617
    Abstract: A mobile wireless apparatus includes a network interface, a storage and a processing device. The network interface provides a wireless protocol of a personal area network. The storage stores access codes and location indicators. Instead of scanning coverable external apparatuses every time when the mobile wireless apparatus moves from one location to another, the processing device connects to the external apparatuses by reference to the access codes and the location indicators.

  • Publication number: 20070007168
    Abstract: The present invention is a separation method and system in which granulation of coupled post-extraction asphalt residue is used to achieve deep separation of heavy oil. A dispersion solvent is introduced into the asphalt phase after separation by solvent extraction and the asphalt phase undergoes rapid phase change in a gas-solid separator and is dispersed into solid particles while the solvent vaporizes, resulting in low temperature separation of asphalt and solvent with adjustable size of the asphalt particles. The separation method of this invention also includes a three-stage separation of heavy oil feedstock, in which the deasphalted oil phase separated from heavy oil is treated with supercritical solvent and results in the further separation of the resin portion of the deasphalted oil, maximizing the yield and quality of the deasphalted oil.
