Each housing includes quartz tubes (16, 80) fixedly supported at an upper plate (12, 106) while being movably supported at a lower plate (14, 104). Each tube has a UV light emitter that can eradicate microorganisms in a liquid. The tube support arrangement includes a plurality of tube retainer assemblies. Each retainer assembly includes a tube holding cup (30, 90) surrounded by a coil spring (24, 94). Each cup includes an upper lip (34), a lower lip (36), and a foot (42). The lips retain the cup in a lower plate aperture (20,116) while the foot engages the tube's domed end. A cup can hold a tube in the lower plate while constraining lateral movement of the tube, providing spring-biased axial support to the tube, and allowing axially-extending thermal expansion of the tube.

  • Publication number: 20140360947
    Abstract: A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row.

    Abstract: An apparatus and method is provided for treating fluid provided to a patient support. An apparatus comprises a housing defining an interior space, an inlet in flow communication with a source of untreated fluid and the interior space, an outlet in flow communication with the patient support and the interior space, and a light source directed into the interior space such that light emitted by the light source bombards fluid flowing through the interior space with light within a wavelength range that destroys organisms within the fluid to thereby provide treated fluid to the patient support.

  • Publication number: 20140238234
    Abstract: An aircraft has a ventilation system that employs a plurality of nozzles positioned in a cavity between a sidewall of the aircraft cabin and a section of the aircraft fuselage. The nozzles receive a supply of ventilation air and direct jets of air from the nozzles, through the cavity and into the aircraft cabin. The jets of air produced by the nozzles create low-pressure areas in the cavity. At least one return air opening in the cabin sidewall communicates the low-pressure areas with the cabin interior, whereby the low pressure areas draw air from the cabin interior into the cavity where the drawn air is entrained with the jets of air produced by the nozzles. Devices inside the cavity remove suspended impurities from the air drawn into the cavity. In this manner, the ventilation system filters or sanitizes the air drawn through the system.

  • Patent number: 8816301
    Abstract: Germicidal lamp apparatuses are provided with lamps disposed between upper and lower bases of a support structure. In some embodiments, a longitudinal axis of a lamp is at an acute angle greater than 0° relative to a region of the lower base between the lamp and another lamp. In addition, the longitudinal axis of the other lamp is at either a right angle or an obtuse angle relative to said region. Other embodiments of apparatuses include a reflector system disposed between the upper and lower bases which is common to the lamps and which includes a reflector with slanted peripheral edge. Other germicidal lamp apparatuses are provided which include a reflector with multiple sections each contoured to manipulate directionality of light emitted from a subset of lamps. In such cases, the apparatuses are configured to move the reflector and/or collectively move the lamps during illumination of the lamps.

  • Patent number: 8779384
    Abstract: A clean water dispensing device is disclosed. The device includes a pure water tank (10), a sterilization tube (20), a sterilization lamp (30) and a transit tube (32). The pure water tank is fitted into a cold water tank (5) in such a way that a closed space is defined between the cold water tank and the pure water tank. Drinking water is drawn into an inlet port of the sterilization tube and passes through the transit tube before being stored in the cold water tank through an outlet port of the sterilization tube. The closed space is prevented from making contact with outside air, and only drinking water that has been sterilized by the sterilization tube is supplied into the closed space. Therefore, even if cold water is stored in the closed space for a long period of time, there is little possibility of the propagation of bacteria.
