  • Patent number: 11084890
    Abstract: A magnesium alkoxide catalyst support and the preparation method and use thereof are provided. The method for preparing the magnesium alkoxide catalyst support comprises the following steps: mixing a metallic magnesium, a monohydric alcohol, a halogenating agent and a surfactant at 0° C. to 90° C. under an inert gas atmosphere, and then washing the resultant with an inert solvent to obtain the magnesium alkoxide catalyst support. A magnesium alkoxide catalyst support obtained by the above method is also provided, which can be used to catalyze olefin polymerization. The magnesium alkoxide catalyst support obtained by the above method according to the invention has excellent particle morphology and controllable size, and is suitable for preparing a catalyst for olefin polymerization.

  • Patent number: 10185606
    Abstract: Methods and apparatus for inter-process communication are provided. A circuit may have a plurality of clusters, and at least one cluster may have a computation element (CE), a memory operatively coupled with the CE, and an autonomic transport system (ATS) block operatively coupled with the CE and the memory. The ATS block may be configured to perform inter-process communication (IPC) for the at least one cluster. In one embodiment, the ATS block may transfer a message to a different cluster based on a request from the CE. In another embodiment, the ATS block may receive a message by allocating a buffer in the memory and write the message into the buffer. The ATS block may also be configured to manage synchronization and schedule tasks for the CE.
