Abstract: A synthesis process of trans-1,4-polyisoprene, using bulk precipitation polymerization of isoprene catalyzed by supported titanium catalyst TiCl4/MgCl2. The process includes prepolymerizing carried out in a prepolymerization reactor with an anchor agitator; polymerizing carried out in a polymerization reactor with a helical ribbon agitator; and devolatilizing and drying carried out in a vacuum rake dryer. Not only does the process require lower energy consumption and thus a lower production cost, but it also eliminates the emission of three wastes.

Abstract: A self-assignment method for assigning detector and working devices among a plurality of access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more other transmitting access devices. The method records radio frequency (RF) data associated with beacons received during the wireless data collection, and thereafter automatically designates at least one of the access devices as a detector device, based upon the recorded RF data.

Abstract: A method comprising providing a halogen stream; providing a first alkane stream; reacting at least a portion of the halogen stream with at least a portion of the first alkane stream to form a halogenated stream, wherein the halogenated stream comprises alkyl monohalides, alkyl polyhalides, and a hydrogen halide; providing a second alkane stream; and reacting at least a portion of the second alkane stream with at least a portion of the alkyl polyhalides to create at least some additional alkyl monohalides.

Abstract: A self-configuration method for access devices in a wireless network begins by performing wireless data collection with the access devices during an automated calibration period. During this time, each access device receives beacons from one or more transmitting access devices, the beacons being transmitted and received using a plurality of different channels available to the wireless network. The method records radio frequency (RF) data associated with the received beacons, and processes the RF data to select, from the plurality of different channels, a respective channel for each of the access devices. In addition, the RF data is processed to adjust transmit power levels for the access devices. The selected channels and adjusted transmit power levels are then used as configuration settings for the access devices.

Abstract: A system, apparatus and techniques for detecting and self-healing coverage hole conditions in a wireless network are disclosed. The apparatus includes a monitor module that is configured in a data forwarding plane of a network switch and a regulatory module configured in a control plane of the switch. The monitor module is configured to detect a coverage hole condition affecting a mobile device associated with an access port and the regulatory module is configured to adjust transmission power to the access port based on the condition.

Abstract: Hybrid articles comprising a molded mixture of a light metal alloy and a polymer are formed by processing (including co-molding and co-extruding) the metal in a semi-solid state at a high shear rate and the polymer in a melt processable state. For example, magnesium alloy particles in a thixotropic condition are mixed with particles or globules of the polymer and molded into a hybrid metal-containing and polymer-containing body. The proportions of magnesium and polymer may be varied substantially depending on the desired properties of the hybrid article. In another embodiment the light metal and polymer may be co-extruded as two or more distinct layers into a solid or hollow hybrid body.

Abstract: A method for attaching an aluminum panel to a magnesium panel via a self-piercing rivet. The method includes positioning the aluminum panel and the magnesium panel together with the magnesium panel supported on an anvil having a cavity therein. The magnesium panel is spot heated at the locale of the anvil, and then the self-piercing steel rivet is punched through the steel panel and only partway into the magnesium panel, to displace the magnesium panel into the cavity. The heating of the magnesium improves the ductility so that the self-piercing rivet is accepted without undue strain on the magnesium material. The interface between the steel rivet and the magnesium panel is concealed between the aluminum panel and the magnesium panel to thereby protect the interface between the steel material of the rivet and the magnesium panel from exposure to the environment.
