  • Publication number: 20150312453
    Abstract: Techniques for switchable camera mirror apparatus are described. In one or more embodiments, a computing device (e.g., a tablet device, a smartphone, and so on) includes a camera functionality that is configured to capture images from a variety of different device perspectives. The camera functionality, for instance, can enable images to be captured from a front-facing device perspective, a rear-facing device perspective, and so on. Included as part of the camera functionality is a switchable mirror apparatus that is switchable to alternately reflect light from different device perspectives, such as to enable images to be captured from at least some of the different device perspectives using a single image sensor.

  • Patent number: 8852541
    Abstract: Systems and methods for removing impurities from a feed fluid in a single vessel. A method generally includes, in single vessel, contacting a feed fluid passing through the vessel with a copper-based material for removing oxygen from the feed fluid; and contacting the feed fluid passing through the vessel with an adsorbent for removing at least one of water, carbon dioxide, and oxygenated hydrocarbons from the feed fluid.

  • Patent number: 8129483
    Abstract: A continuous gas phase circulating bed reactor, including: a riser for contacting a catalyst and a first gas composition comprising an olefin to form a polyolefin under fast-fluidization regime or a dilute-phase pneumatic conveying regime conditions; a downer for contacting the catalyst and a second gas composition comprising an olefin to form additional polyolefin under fast fluidization regime or a dilute-phase pneumatic conveying regime conditions; and a transport section for conveying at least a portion of the catalyst, polyolefin, and additional polyolefin from the downer to the riser. Also disclosed is a polymerization process using such a circulating bed reactor.

  • Patent number: 7878431
    Abstract: A rotary feeder for feeding a particulate material including: a cylindrical housing comprising a feeder inlet, a first feeder outlet, and a second feeder outlet; a rotor mounted in the cylindrical housing including a plurality of substantially impeller blades defining a plurality of circumferentially spaced pockets alignable with the feeder inlet, first feeder outlet, and second feeder outlet, and adapted to sweep a wall of the cylindrical housing as the rotor rotates in the cylindrical housing; a device for rotating the rotor; and a separating screen in the first feeder outlet to substantially prevent oversize material from exiting through the first feeder outlet, wherein each of the plurality of circumferentially spaced pockets will align with the feeder inlet to receive therein a particulate material and an oversize material through the feeder inlet, rotate in the cylindrical housing to align with the first feeder outlet and discharge the particulate material therefrom, and rotate in the cylindrical housin

  • Patent number: 4981929
    Abstract: Highly stereospecific olefin polymers are obtained in enhanced yield in a continuous gas-phase fluid bed process for polymerizing alpha monoolefins employing a catalyst system comprising (a) a solid titanium-containing procatalyst, (b) an organoaluminum activator compound, and (c) a selectivity control agent, by continuously adding dialkylaluminum halide to the reactor during polymerization and conducting polymerization at a temperature of 0.1.degree. to 5.0.degree. C. above the dew point temperature of the cycle gas in the reactor.
