Patent number: 10651646Abstract: A fault current limiter, including: two inductors, a direct current circuit breaker, a shunt resistor, a first fixed resistor, and metal oxide arresters. The two inductors include wound superconducting wires. The inductors have identical number of windings and identical structure. Magnetic fluxes of the inductors are forward coupled, and the inductors are connected in parallel to form a superconducting inductor structure. The direct current circuit breaker and the superconducting inductor structure are connected in series to form a series branch. The shunt resistor is connected in parallel to the series branch. The first fixed resistor is connected in parallel to the direct current circuit breaker. The metal oxide arresters are two in number, and are connected to two ends of the inductors in parallel.Type: GrantFiled: June 13, 2017Date of Patent: May 12, 2020Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Li Ren, Siyuan Liang, Yuejin Tang, Ying Xu, Zhong Xia, Zuoshuai Wang, Jing Shi, Jingdong Li, Lihui Zhang, Sinian Yan, Zhangwei Yang, Yi Zhang

Patent number: 9062155Abstract: The present invention relates to a method for producing an organometallic catalyst and an organometallic catalyst when produced by the method. The method comprises the steps of combining a polycarboxylic acid or anhydride and a metal-oxide, metal-hydroxide or metal-salt with a solvent at a temperature and pressure at which the solvent exists as a supercritical or near-critical fluid. The polycarboxylic acid or anhydride is reacted with the metal-oxide, metal-hydroxide or metal-salt for sufficient time and under sufficient temperature and pressure to produce the organometallic catalyst. The present invention also relates to a process for making a poly(alkylene carbonate) in the presence of a catalytic amount of the organometallic catalyst produced by the method.Type: GrantFiled: July 18, 2013Date of Patent: June 23, 2015Assignee: University of SydneyInventors: Fariba Dehghani, Zhong Xia
