Flow-enclosed Radiation Source Patents (Class 250/436)
  • Patent number: 8497491
    Abstract: An air disinfection device aimed at improving the efficiency and quality of air disinfection or sterilization may be achieved through an air disinfection device comprising a body housing a power supply and control unit, which, in turn, comprises an energy storage capacitor, a high-voltage constant current source, an ignition pulse generator, a ferrite-core pulse transformer, and a program control unit. The air disinfection device may also comprise an ultra-violet radiation source in the form of a pulsed gas-discharge lamp mounted on the body and enclosed in a tubular quartz casing. Given that the energy storage capacitor and the pulsed gas-discharge lamp may form a discharge circuit connected to the ignition pulse generator through the ferrite-core pulse transformer, the pulsed gas-discharge lamp may be placed in a bactericidal radiation translucent casing, resulting in convection air-cooling due to a natural draft inside the casing that disinfects and sterilizes surrounding air.

  • Patent number: 8071959
    Abstract: An 82Sr/82Rb generator column is made using a fluid impervious cylindrical container having a cover for closing the container in a fluid tight seal, and further having an inlet for connection of a conduit for delivering a fluid into the container and an outlet for connection of a conduit for conducting the fluid from the container. An ion exchange material fills the container, the ion exchange material being compacted within the container to a density that permits the ion exchange material to be eluted at a rate of at least 5 ml/min at a fluid pressure of 1.5 pounds per square inch (10 kPa). The generator column can be repeatedly recharged with 82Sr. The generator column is compatible with either three-dimensional or two-dimensional positron emission tomography systems.

  • Publication number: 20110272155
    Abstract: A method of treating a wellbore servicing fluid includes disposing an ultraviolet treatment chamber in fluid communication with an inlet of a pump, operating the pump, and drawing a wellbore servicing fluid through the ultraviolet treatment chamber in response to operating the pump. A wellbore servicing fluid treatment system has a first ultraviolet treatment chamber and a first pump in selective fluid communication with the first ultraviolet treatment chamber. The pump is downstream relative to the first ultraviolet treatment chamber and the pump is configured to selectively draw a wellbore servicing fluid through the first ultraviolet treatment chamber. A method of servicing a wellbore includes connecting an ultraviolet fluid treatment system to a blender, operating a pump of the blender, drawing a wellbore servicing fluid through the ultraviolet treatment system in response to operating the pump of the blender, and delivering the wellbore servicing fluid into the wellbore.

  • Publication number: 20110253904
    Abstract: The output wavelengths of an electrodeless lamp are controlled by passing a fluid over the surface of the lamp to control its temperature. The stabilized temperature prevents thermal runaway of the lamp and stabilizes the output wavelengths of the lamp. When the fluid passing over the lamp is water, the lamp can be used for sanitary treatment of the water. Lamp radiation can be enhanced by shaping the electrodeless lamp to provide maximally effective photonic output.

  • Publication number: 20110240880
    Abstract: There is described a fluid treatment system which may which may be used with radiation sources that do not require a protective sleeve—e.g., excimer radiation sources. An advantage of the present fluid system treatment is that the radiation sources may be removed from the fluid treatment zone without necessarily having to shut down the fluid treatment system, remove the fluid, break the seals which retain fluid tightness, replace/service radiation source and than reverse the steps. Instead, the present fluid treatment system allows for service/replacement of the radiation sources in the fluid treatment zone during operation of the fluid treatment system.

  • Publication number: 20110215055
    Abstract: A method and an apparatus are described for use in the irradiation of fluids. The apparatus has an elongate conduit (312) having a central axis (334) and two or more elongate ultraviolet radiation sources (114) extending along the interior of the conduit for irradiation of the fluid within the conduit. An array of static mixer elements (300) is located within the conduit, and the two or more elongate ultraviolet radiation sources (114) are arranged to extend through apertures in deflection surfaces of the static mixer elements making up the array (300). The apparatus and method allows for reliable and uniform ultraviolet irradiation of fluids of low UV transmissivity, such as turbid fluids, particularly for ultraviolet disinfection of such fluids. Wipers may be fitted to the static mixer elements to enable relative movement between the static mixer elements and the surfaces of the elongate ultraviolet radiation sources to clean the surfaces of the sources without need to dismantle the apparatus.
