  • Patent number: 8834819
    Abstract: A powder lime calcining process comprises: transporting fine granules of limestones having a water content less than 4%, and a granule size less than 15 mm, from a raw material storing bin to a small material bin, transporting the materials from the small material bin into an airflow pipe by a belt conveyer, heating and drying the materials, sieving the materials by a sieving device, transporting granules into a cyclone cylinder deduster and a clothbag deduster in turn by airflow pipes, the fine powders of limestones after dedusted are transported into an intermediate bin; the materials within the intermediate bin are transported to four preheating cyclone cylinders by a pneumatic lift pump and airflow pipes, and are preheated and separated; the materials after separated are transported into three cooling cyclone cylinders for cooling and separating the materials, finally transported into a finished product bin by a finished product transporting system.

  • Patent number: 8392889
    Abstract: A network based algorithmic Service Objective (SO) is evaluated by defining an SO script comprising a plurality of Service Indicators (SIs), each of the SIs comprising an equation including a plurality of operands and at least one operator, instantiating the SO script into an object-oriented representation of the SO, obtaining values for each of the plurality of operands, and computing each of the SI equations using the obtained values.

  • Publication number: 20020039352
    Abstract: Embodiments of methods, systems, and computer program products are provided for managing a service. For example, service quality and/or performance requirements may be obtained from a client and quality and/or performance data may be collected from the network. The collected quality and/or performance data may then be compared with the service quality and/or performance requirements to determine if the network quality and/or performance requirements are satisfied. Thus, a service may be comprehensively managed by using collected quality and/or performance data from the network to verify that the network is providing a level of service expected by a client.
