  • Silicon-and germanium-based SCM-25 molecular sieve, preparation process and use thereof
    Patent number: 11952283
    Abstract: A silicon-and germanium-based molecular sieve has a framework chemical composition as represented by the formula “SiO2.1/nGeO2”. The silicon/germanium molar ratio is 0.1n30. The molecular sieve has a unique X-ray diffraction pattern. It can be used in adsorptive separation, ion exchange, and catalytic conversion of organic compounds.

  • System, method and apparatus for dynamic path protection in networks
    Publication number: 20050237950
    Abstract: The present invention provides a system, method and apparatus for dynamic path protection in networks by finding two paths between a source node and a destination node in a network having multiple nodes and multiple links. A first path is found between the source node and the destination node using a routing algorithm and a model of the network. Each link has a cost and at least one risk identifier. The cost of the links having one or more risk identifiers that occur more than once in the network model are increased. The model is modified by removing all links in the first path and all links having one or more risk identifiers in common with any of the risk identifiers of the links in the first path. The second path is found between the source node and the destination node using the routing algorithm and the modified model.
