Publication number: 20210228766Abstract: A microsphere includes a cross-linked hydrophilic substrate, a lipophilic substrate, and a surfactant. The cross-linked hydrophilic substrate includes cross-linked sodium alginate and gelatin. The lipophilic substrate includes iodized oil, C16-C18 alkyl alcohol, and polycaprolactone. The surfactant includes polyoxyethylene stearate. The microsphere is dry or substantially solid. Prior to being used for embolization, the microsphere can be immersed in a drug containing mixture to allow the microsphere to absorb the mixture and expand, thereby loaded with the drug. A method for preparing the microsphere and a method for embolizing tumor in a subject by using the microsphere are also provided.Type: ApplicationFiled: May 31, 2018Publication date: July 29, 2021Applicants: T-ACE Medical Co., Ltd., T-ACE Medical Co., Ltd.Inventors: CHIH HONG CHEN, CHAU NAN HONG, CYUN JHE YAN, CHUEH KUAN WANG, CHEN HSI CHOU, YI SHENG LIU, HONG MING TSAI, CHI MING HO, CHUAN SHENG LIN, XI ZHANG LIN

Patent number: 8677761Abstract: Systems and methods for controlling compressor extraction air flows from a compressor of a turbine system during engine turn down are provided. In one embodiment, a method for controlling compressor extraction air flows from a compressor of a turbine system during turn down includes a control unit monitoring one or more operating parameters of a turbine system associated with an exit temperature of a combustor of the turbine system. The method further includes the control unit detecting one or more operating parameters meeting or exceeding a threshold associated with a decrease in the exit temperature of the combustor. In response to detecting one or more operating parameter meeting or exceeding the threshold, a control signal is transmitted to at least one variable orifice located in the turbine system causing at least one variable orifice to alter at least one extraction air flow from the compressor.Type: GrantFiled: February 25, 2009Date of Patent: March 25, 2014Assignee: General Electric CompanyInventors: David Leach, Jason Nathaniel Cook, Chi Ming Ho

Supported ruthenium nanoparticle catalyst for cis -dihydroxylation and oxidative cleavage of alkenes
Patent number: 7393985Abstract: The present invention relates to the use of nanosized metal particles (e.g., ruthenium) grafted on inert solid support for oxidation of alkenes. The supported metal catalyst can effect cis-dihydroxylation and oxidative cleavage of alkenes to give the respective cis-diols and carbonyl products.Type: GrantFiled: April 19, 2005Date of Patent: July 1, 2008Assignee: The University of Hong KongInventors: Chi-Ming Che, Wing-Yiu Yu, Chi-Ming Ho -
Patent number: 7324203Abstract: A method for in-situ monitoring of an emission product includes transmitting a light, tuning the light to a first wavelength, receiving the light at a second location, varying the light from the first wavelength to a second wavelength during a first period, measuring a first absorption line and a first non-absorbing baseline signal during the first period, switching the light to a third wavelength, varying the light from the third wavelength to a fourth wavelength over a second period, and measuring a second absorption line and a second non-absorbing baseline signal during the second period. The light is transmitted from a first location by a tunable light source and received at a second location. The light passes along an optical path through the emission product between the first and second locations. The first wavelength corresponds to the first absorption line of the emission product. The third wavelength is different from the first and second wavelengths.Type: GrantFiled: February 8, 2005Date of Patent: January 29, 2008Assignee: General Electric CompanyInventor: Chi Ming Ho

Patent number: 6684878Abstract: An outdoor condensing furnace is provided with a condensate drain line which passes through the heat exchange compartment and to a location within the building where it can be discharged at temperatures above freezing. During heating operation, the drain line is maintained at temperatures above freezing such that the condensate will not freeze, and if condensate is trapped in the drain line and freezes during periods of nonheating operation, then it will be quickly thawed when heating operation is resumed. In an alternate embodiment, a drain pan is placed in direct contact with the primary heat exchanger and the condensate is routed to drain pan to be vaporized. Another embodiment provides for routing of the condensate from the condensing heat exchanger, through a flue pipe, and to a drain site which is at above freezing ambient conditions.Type: GrantFiled: October 11, 2001Date of Patent: February 3, 2004Assignee: Carrier CorporationInventors: Chi Ming Ho, Alan Dale Abbott
