Publication number: 20240092948Abstract: The present invention relates to a process for continuously producing an ultra-high molecular weight polyethylene by the ethylene slurry polymerization, wherein raw materials containing ethylene and optionally at least one comonomer are subjected to a continuous slurry polymerization in a hydrogen free atmosphere in the ethylene slurry polymerization condition by using 2-6 ethylene slurry polymerization reaction tanks connected in series, and the deviations of the polymerization temperatures, the polymerization pressures, and the gas phase compositions between the tanks each other are controlled to certain ranges. The ultra-high molecular weight polyethylene having the viscosity-average molecular weight of 150-800×104 g/mol can be continuously produced. This process has flexible polymerization manner, large room for adjusting and controlling, and stable polymer performance.Type: ApplicationFiled: January 26, 2022Publication date: March 21, 2024Inventors: Chuanfeng LI, Wenrui WANG, Kun JING, Minghua CHEN, Yuejun XING, Huimin XIA, Feng GUO, Zhonglin YOU, Shaohui CHEN, Jianhong ZHAI, Liu YANG, Songtao TU

Publication number: 20190306951Abstract: A portable electrical device, such as an electrical lighting device, comprises a charging channel configured for directing electrical power from the electrical device to a separate electrical device connected via the charging channel (e.g., a charging port). While the charging port is unused, the electrical device generates outputs (e.g., lighting outputs) at a first output power level (e.g., a first brightness). The electrical device also comprises an onboard controller configured to monitor the charging channel, and upon detecting an electrical device connected via the charging channel, the onboard controller decreases the output power to a second output power level (e.g., a second brightness) to conserve power.Type: ApplicationFiled: April 2, 2018Publication date: October 3, 2019Inventors: Michael J. Brandon, II, Stephen E. Osmialowski, Liu Jing

Patent number: 8473499Abstract: Techniques for unsupervised management of a question and answer (QA) forum include labeling of answers for quality purposes, and identification of experts. In a QA thread, a ranking of answers may include an initial labeling of the longest answer in each thread as the best answer. Such a labeling provides an initial point of reference. Then, in an iterative manner answerers are ranked using the labeling. The ranking of answerers allows selection of experts and poor or inexpert answerers. A label update is performed using the experts (and perhaps inexpert answerers) as input. The label update may be used to train a model, which may describe quality of answers in one or more QA threads and an indication of expert and inexpert answerers. The iterative process may be ended upon convergence or upon a maximum number of iterations.Type: GrantFiled: October 17, 2011Date of Patent: June 25, 2013Assignee: Microsoft CorporationInventors: Young-In Song, Liu Jing, Chin-Yew Lin, Tetsuya Sakai
