  • Patent number: 9255162
    Abstract: Process for the polymerization of olefins in a gas phase fluidized bed reactor, by i) passing a fluidizing gas to the reactor to fluidize a bed of polymer particles therein, ii) withdrawing the fluidizing gas from the reactor, iii) cooling all or a portion of the fluidizing gas withdrawn from the reactor to a temperature at which a portion of the components of the fluidizing gas condense to form condensed liquid, and iv) passing condensed liquid and non-condensed components of the fluidizing gas back to the reactor. A reservoir of condensed liquid downstream of the cooling step is provided, and variations in the inventory of the condensed liquid are made in order to control the temperature in the reactor.

  • Patent number: 9094434
    Abstract: A prevention-based network auditing system includes a central compliance server providing a user interface allowing a user to schedule and configure a network audit. The configured audit is stored in an audit repository until its scheduled time. At such a time, the compliance server automatically invokes one or more audit servers to gather information about the network. The compliance server receives the gathered information and electronically applies a network policy to the information for determining compliance with the policy. A remediation task may be generated if the policy has been violated, and the task monitored until its completion.

  • Patent number: 8793763
    Abstract: A prevention-based network auditing system includes a plurality of heterogeneous information sources gathering information about the network. An audit server invokes the heterogeneous information sources via a uniform communications interface to gather information about the network, and converts the information gathered by the information sources into a normalized data format such as, for example, into XML (Extensible Markup Language). The converted information is then stored in an audit repository for security and regulatory policy assessment, network vulnerability analysis, report generation, and security improvement recommendations.
