  • Patent number: 11634335
    Abstract: The present invention provides an iron-loaded aluminosilicate zeolite having a maximum pore opening defined by eight tetrahedral atoms and having the framework type CHA, AEI, AFX, ERI or LTA, wherein the iron (Fe) is present in a range of from about 0.5 to about 5.0 wt. % based on the total weight of the iron-loaded aluminosilicate zeolite, wherein an ultraviolet-visible absorbance spectrum of the iron-loaded synthetic aluminosilicate zeolite comprises a band at approximately 280 nm, wherein a ratio of an integral, peak-fitted ultraviolet-visible absorbance signal measured in arbitrary units (a.u.) for the band at approximately 280 nm to an integral peak-fitted ultraviolet-visible absorbance signal measured in arbitrary units (a.u.) for a band at approximately 340 nm is >about 2.

  • Patent number: 10038594
    Abstract: Systems and methods are provided for centralized access, control, and management of APs. According to one embodiment, multiple APs of a private IP network are decoupled from potentially transient IP addresses by assigning a unique identifier to each of the multiple APs by an AC. An AC GUI is presented by the AC to an administrator through which (i) commands are provided by the administrator and (ii) the administrator is provided with access to a first AP of the multiple APs responsive to a command received from the administrator though the AC GUI and based upon the first AP's assigned unique identifier. The first AP is accessed, controlled or debugged by the AC based on the command. The access to the first AP enables a first AP GUI of the first AP through which the network administrator is provided with an ability to issue multiple commands to the first AP.

  • Patent number: 9331900
    Abstract: Systems and methods are provided for centralized access, control, and management of access points (AP) in a network architecture to facilitate easy and efficient maintenance and monitoring of access points, for example. Systems and methods are also provided for assigning unique identifiers to one or more access points, and use the identifiers through an interface, such as a command line interface (CLI) of an access controller (AC), to manage and monitor the one or more access points through their respective interfaces. System of the present disclosure further enables transitioning from CLI of a first access point to CLI of a second access point without going through AC.

  • Patent number: 8053032
    Abstract: The invention relates to a method for production of a zeolite layer on a substrate containing metal, comprising the following method steps: production of an aqueous suspension, comprising several components, one component comprises at least one cross-linking element from the third, fourth or fifth main group of the periodic table, the substrate containing metal comprises at least one of the cross-linking elements, introduction of the substrate containing metal to the aqueous suspension, heating the aqueous suspension and the substrate containing the metal present therein for the in-situ crystallisation of a zeolite layer on the substrate containing metal, whereby the cross-linking elements in the substrate containing metal are extracted and included in the zeolite layer, a cross-linking element present in the suspension for formation of the zeolite layer is present at a concentration so low that a crystallisation in the suspension is largely or completely avoided and said element is principally provided by th
