  • Patent number: 11219255
    Abstract: The present invention relates to a protective face mask and filtration article, a method for using a protective face mask and filtration article, and a design for manufacturing. In particular, the invention relates to a self-contained, mobile, battery-powered bioactive and filtering breathing appliance that provides broad spectrum antimicrobial and allergic protection via an atomized biocidal agent steam/vapor and a torturous hydrophilic filtration article that sterilizes incoming air and captures debris. To this end, antimicrobial activity and filtration functions leverage a redundancy of means/methods comprised of antimicrobial hydrogen peroxide liquid/vapor/steam and an iodized salt containing hydrophilic filtration article. The present invention is a wearable apparatus that sterilizes incoming air by capturing, neutralizing and destroying airborne pathogens and other particulate matter and pumps sterilized oxygen/air for natural, unlabored breathing by the wearer.

  • Patent number: 8435387
    Abstract: The present invention generally relates to the small-scale separation of a mixture of two or more components with different boiling points into enriched fractions. In some embodiments, a first and second fluid (e.g., a liquid and a gas, a liquid and a liquid, etc.) are passed through a channel. The first fluid may include at least two components, each with a unique boiling point. Upon contacting the first and second fluids within the channel, at least a portion of the most volatile of the components in the first fluid (i.e., the component with the lowest boiling point) may be transferred from the first fluid to the second fluid. In some instances, the transfer of the volatile component(s) from the first fluid to the second fluid may be expedited by heating, in some cases above the boiling point(s) of the component(s) to be transferred from the first fluid to the second fluid. Contact between the first and second fluids may be maintained, for example, via segmented flow, bubbling flow, etc.

  • Publication number: 20120298587
    Abstract: A fluid treatment device and method is proposed for the treatment of a fluid that has components to be separated, such as tailings. The fluid treatment device in one embodiment comprises a motive pump connected to drive fluid to be treated along a conduit through a restriction forming a nozzle into a mixing chamber and thence to a discharge. A port, which may be controlled by a valve, admits gas into an initial portion of the mixing chamber. The motive pump, nozzle, gas port and mixing chamber together form a phase separator. Multiple phase separators may be connected together in series. The mixing chamber may have constant diameter and a length to diameter ratio of 20:1 or 60:1 or more. The conduit terminates in a discharge. The discharge may supply the treated fluid to a secondary separation device such as a flotation cell. Solids and liquids may be taken off the flotation cell for disposal, further processing or delivery into a sales line.

  • Publication number: 20090241579
    Abstract: In a liquid treatment apparatus, a discharge electrode (31) and an ejector (32) are arranged face to face with each other. An electric power supply (33) establishes an electric potential difference between the discharge electrode (31) and the ejector (32). As a result, a streamer discharge occurs from the discharge electrode (31) towards liquid droplets (32a) emitted from the ejector (32). Active species produced in association with the generation of the streamer discharge are absorbed in the liquid droplets (32a), whereby the treatment target water (32a) is sterilized and purified.

  • Patent number: 5156747
    Abstract: Small quantities of one or more liquids having a high boiling point dispersed with a large quantity of one or more immiscible liquids having a lower boiling point are separated in a rapid and efficient manner. A non-reactive compressed gas is heated by recycled energy and make-up energy to a temperature above the boiling point of at least one liquid but below that of at least one other liquid. The heated gas is combined with the unheated liquid mixture to be separated, and the liquid-gas blend is mixed, heated and distributed by an improved nebulizer, forming a mist inside a vessel containing a pool liquid of at least one liquid having a boiling point higher than that of at least one other liquid, which pool liquid has been heated to a temperature above the boiling point of at least one liquid but below its own boiling point. The liquid having high-boiling-point in the mist settles by gravity and merges with the pool liquid.

  • Patent number: 4515754
    Abstract: A scrubber is provided with a grate in its sump through which oxygen is introduced to separate the oxidation zone above this grate from a reaction zone below the grate, a calcium containing additive being introduced into this reaction zone. Flue gas to be desulfurized is passed through a washing zone above the sump and there contacted with normally circulating scrubbing liquid containing the additive to absorb sulfur dioxide and sulfur trioxide. The sulfur dioxide is oxidized to sulfur trioxide and the additive induces precipitation of calcium sulfate in the sump. After a prolonged standstill, settled solids in the sump are induced into movement by drawing a portion of the sump liquid from an upper part thereof and injecting it into a lower part of the sump.
