  • Publication number: 20160273076
    Abstract: The invention provides a method of refining aluminum alloy, which is characterized in that aluminum-based nanometer quasicrystal alloy is used as an aluminum alloy refiner to refine the aluminum alloy; the aluminum-based nanometer quasicrystal alloy does not comprise Si, Fe or Cr; the aluminum-based nanometer quasicrystal alloy consists of (1) Al; (2) Mn and (3) La and/or Ce. The refiner selected in the invention is rare earth-containing alloy which has a strong refinement ability on the aluminum alloy, and is nanometer quasicrystal; after adding the rare earth-containing alloy to melt, the element distribution of the rare earth-containing alloy is more uniform than that of traditional alloy; and nanometer quasicrystal particles substantially increase the number of heterogeneous nucleation particles and improve the grain refinement effect of the aluminum alloy.

  • Publication number: 20120311328
    Abstract: Computing devices can autoconnect to access points even if they have not previously received authentication information for those access points. A computing device broadcasts a probe request, comprising a request for authentication information. An access point receiving such a probe request generates a probe response that provides authentication information that the computing device can then utilize to establish a useful communication connection to the access point. The provided authentication information can be either encrypted or unencrypted, and can be encrypted for specific users or specific computing devices. Dedicated application programs can decrypt encrypted authentication information, thereby enabling autoconnecting, while also delivering targeted information to users of the autoconnecting computing devices from a retailer hosting the access point. Authentication information for a “landing page” can be provided to a web browser to enable autoconnection.
