  • Patent number: 11920089
    Abstract: Pyrolysis processes comprise contacting a waste polyolefin with a solid catalyst at a pyrolysis temperature to form a pyrolysis product containing C1-C10 hydrocarbons. In some instances, the solid catalyst can be a silica-coated alumina, a fluorided silica-coated alumina, or a sulfated alumina, while in other instances, the solid catalyst can be any suitable solid oxide or chemically-treated solid oxide that is characterized by a d50 average particle size from 5 to 12 ?m and a particle size span from 0.7 to 1.7. Hydrocarbon compositions are formed from the pyrolysis of waste polyolefins with specific amounts of methane and higher carbon number hydrocarbons.

  • Patent number: 7114005
    Abstract: A communication system includes translation modules that provide address hopping to secure packet-based communications. A transmitting translation module modifies source and/or destination addresses of communicated packets and a receiving translation module resolves each modified source and/or destination address into the original source and destination addresses for the packets.

  • Patent number: 6510214
    Abstract: A service control point (24) includes an overload control system (50) that determines an overload rating (70) for an intelligent processing unit (82). The overload control system (50) includes a latency estimator (52) that requests and receives a latency (66) for a service logic interpreter (62). A queue depth store (54) receives a queue depth (68) from the service logic interpreter (62). A common memory (56) stores the latency (66) and the queue depth (68) in memory mapped files. A load estimator (58) determines the overload rating (70) in response to the latency (66) and the queue depth (68). The load estimator (58) compares the overload rating (70) to a previous overload rating and issues an internal problem report if a difference is detected. A TCAP interface (60) and a service logic program (64) assess the overload rating (70) to determine if incoming service requests should be passed on to the service logic interpreter (62), rerouted, or discarded.

  • Patent number: 6269396
    Abstract: A method of providing a software interface between application programs performing telecommunications functions and an operating system running on at least one node at a site supporting the application programs, and further forming an interface between the application programs and a telecommunications network is provided. The method includes providing a network platform manager operable to remove nodes from service, restore nodes to service, remove applications from service, and restore applications to service, providing a network system integrity manager operable to monitor the nodes and to enable failed nodes to recover, providing a configuration manager operable to interface with a host coupled to the telecom platform, providing a node platform manager operable to provide management functions for a node, providing a service manager operable to start and stop processes at the direction of the node platform manager, and providing a node system integrity manager operable to monitor inter-node links.

  • Patent number: 5644575
    Abstract: A telecommunications network (10) includes a plurality of transport node controllers (18) that interface with a plurality of local communication processors (16) for the transfer of telecommunications information between subscribers (14) associated with the local communication processors (16) and also for subscribers remote from the transport node controller (18). The transport node controller (18) includes a buffer memory (24) with a pool of buffers (26). A local processor controller (22), in conjunction with a remote processor (20), allocate the buffers (26) within the buffer memory (24) among the plurality of local communication processors (16) and remote communication processors communicating to the transport node controller (18) through a message transporting network (12). The local processor controller (22) assigns a buffer (26) to each of the plurality of local communication processors (16).
