Patent number: 8552363Abstract: An optical chromatography system employs fluid filled hollow core fibers, such as photonic crystal fibers (PCFs), which confine an incident optical beam from a laser, for example, in the core and cause separation of particles in the fluid along the length of the PCF. The incident optical beam is confined in the fluid filled core of the PCF by a periodic lattice of air capillaries surrounding the core. The lattice either creates a lower refractive index in the cladding than in the fluid filled core or creates a 1D photonic bandgap structure where the guiding is accomplished by surrounding the fluid filled core with a periodically changing array of dielectric constant which prohibits radial dilution of the optical energy over a range of wavelengths through photonic bandgap effects.Type: GrantFiled: June 23, 2008Date of Patent: October 8, 2013Assignee: Cornell UniversityInventors: David Erickson, Sudeep Mandal

Publication number: 20130248460Abstract: A system and method for wastewater treatment using ultraviolet (UV) irradiation of wastewater flowing in a treatment chamber. Wastewater to be treated flows into the first UV exposure chamber where it is exposed to UV illumination. Wastewater exposure time is lengthened by channeling the wastewater to first flow down a first UV exposure chamber and then back up through a second UV exposure chamber both of which are in a single structure. The first and second UV exposure chambers are separated by the UV illumination source so that wastewater on the two sides of the UV illumination source (i.e. both UV exposure chambers) cannot mix, and so that UV illumination time is dictated by the flow rate of the wastewater and the length of the UV illumination source. Thus the UV illumination path is roughly twice the length of the UV illumination source.Type: ApplicationFiled: March 23, 2012Publication date: September 26, 2013Inventors: TRENT LYDIC, Thomas Wilkinson, JR., Ronald Swinko

An ultraviolet lamp (8) is disposed so as to reach up to a bottom part of the bent part (6b) by way of the opening part (2c) from inside of the cold water tank (2), so that ultraviolet rays emitted from the ultraviolet lamp (8) may be emitted uniformly both in the cold water tank (2) and in the duct of the cold water pour tube (6). As a valve body of a cold water pour valve (7), a diaphragm (71) for clogging the leading end of the cold water pour tube (6) is used, and dead angle of ultraviolet rays is eliminated.Type: GrantFiled: September 26, 2008Date of Patent: December 18, 2012Assignee: Noritz CorporationInventors: Masaaki Matsuda, Hidehiro Takano, Takao Morigaki

Patent number: 8324595Abstract: Bacteria in water 9 exposed outdoors are effectively killed with ultraviolet (UV) light by suppressing post-treatment increase in the bacteria population due to photoreactivation. The apparatus shines UV light on the water 9 to kill bacteria and has UV light emitting diodes (LEDs) 1 that emit UVA light with a primary emission peak of 320 nm-400 nm. The antibacterial action of the UVA light emitted by the UV LEDs 1 prevents proliferation of bacteria in the disinfected water 9 due to photoreactivation.Type: GrantFiled: November 21, 2009Date of Patent: December 4, 2012Assignee: The University of TokushimaInventors: Akira Takahashi, Yohsuke Kinouchi, Masatake Akutagawa

Patent number: 8282880Abstract: A bottle, a system and a method sterilize a liquid. The bottle has an interior to hold the liquid and an ultraviolet light emitting lamp that extends into the interior. A cord may be attached to the bottle so that pulling the cord may power the ultraviolet light emitting lamp and/or charge a battery used to power the ultraviolet light emitting lamp. The bottle may have a status light that indicates that the ultraviolet light emitting lamp may have an amount of power equal to or greater than a threshold value, such as, for example, an amount of power necessary for the ultraviolet light emitting lamp to operate for ninety seconds. The bottle may have a removable lid located opposite to the ultraviolet light emitting lamp.Type: GrantFiled: August 12, 2009Date of Patent: October 9, 2012Assignee: Neverest Travel SolutionsInventor: Eric James

Publication number: 20120248330Abstract: Disclosed herein is an ultraviolet sterilizer having a watertight function. The ultraviolet sterilizer includes a housing and an ultraviolet sterilization unit. The housing has an inlet through which ballast water is drawn into the housing, and an outlet through which the ballast water is discharged from the housing after the ballast water has been sterilized. The ultraviolet sterilization unit is provided in the housing and includes an ultraviolet lamp applying ultraviolet rays to the ballast water to sterilize the ballast water. The ultraviolet sterilizer further includes a cap which supports each of the opposite ends of the ultraviolet sterilization unit and is watertightly coupled to the housing. Thus, even if the ultraviolet sterilization unit is damaged, ballast water is prevented from being drawn into a reception space which contains external devices, and explosive gas which may cause the ultraviolet sterilizer to explode is also prevented from entering the cap.Type: ApplicationFiled: June 18, 2010Publication date: October 4, 2012Applicant: Panasia Co.LtdInventors: Soo-Tae Lee, Tae-Sung Pyo, Su-Kyu Lee

Patent number: 8278627Abstract: A sample feeding device for a trace detector is disclosed. The sample feeding device comprises: a sample feeding chamber disposed in the sample feeding device to desorb a sample from a sample feeding member; and a valve assembly configured to fluidly communicate the sample feeding chamber with a drift tube of the trace detector during feeding sample. With the above configuration of the present invention, for example, the sensitivity of the detector can be increased by improving the permeation ratio of the sample. In addition, interior environment of the drift tube is isolated from exterior environment to avoid a drift region of the drift tube from being polluted. The important parameters, such as sensitivity, a position of a peak of a substance, a resolution, of the detector can be kept constant. As a result, operation reliability and consistency of the detector can be achieved.Type: GrantFiled: May 16, 2011Date of Patent: October 2, 2012Assignees: Nuctech Company Limited, Tsinghua UniversityInventors: Yuanjing Li, Zhiqiang Chen, Qingjun Zhang, Shaoji Mao, Ziran Zhao, Yinong Liu, Shiping Cao, Yan Zheng, Jianping Chang, Xiang Zou
