  • Patent number: 11369712
    Abstract: One or more air baffles are provided for an apparatus that sterilizes air in a room using UVC radiation. At least one baffle within an air sterilization enclosure is arranged so the baffle is proximal to the at least one UVC light source. The baffle is designed and positioned to create air turbulence within the enclosure to increase the dwell time of a given volume of the air in the enclosure, and to reduce the effective distance of a given volume of air to the UVC light sources. Thus, airflow is hindered by the baffle in its passage through the enclosure in order to increase the UVC exposure to that volume of air.

  • Patent number: 10449264
    Abstract: A device in which exhaust fluid from a facility or equipment for treating biologically active material is heated to a temperature of at least 400° C. to kill or denature hazardous agents, and conveyed through a metal filter with no more than 0.1 ?m pore size, which is heated, preferably by the fluid, to essentially the same temperature. The relevant temperature is maintained during operation in both the fluid and the filter. Since the filter is dimensioned to trap microbial agents like bacteria and viruses and the temperature of the filter surfaces is sufficient for sterilization, microbial agents are bound to come into contact with said surfaces and a very high degree of sterilization certainty is reached. The filter is welded to the device body to provide a seamless structure. Heating and filtration are both alone sufficient for removing biohazardous agents, so the device provides double security.

  • Patent number: 9526807
    Abstract: The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

  • Patent number: 9452379
    Abstract: An apparatus and method for abating ozone and reducing sulfuric acid from an exhaust stream. In a semiconductor manufacturing plant the processing of wafers involves the cleaning and etching of wafers, the resultant processing may produce gasses which must be abated. The apparatus and method utilizes UV light in high doses to convert ozone (O3) to oxygen (O2). By ensuring laminar flow through the UV light chambers, the efficiency of the system is sufficient to allow for the remaining impurities in the exhaust air to be removed through the use of an RTO.

  • Patent number: 9370592
    Abstract: The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.

  • Patent number: 9371588
    Abstract: The present invention relates to the application of polymeric resins and TiO2 doped with polymeric resins as coatings for external metal surfaces for industrial use, by selecting the following metals: stainless steel, carbon steel and copper. Focuses specifically on the synthesis of a polymeric resin waterborne corrosion consisting of nano-structured polymer particles formed with two or more acrylic monomers, vinyl or styrenic a functionalizing agent and a crosslinking agent from 1.0 to 20% w each. Doping addition is made of the same polymeric resins, which are incorporated in nanotubes of titanium dioxide in concentrations ranging from 50 to 10,000 ppm. The polymeric resin is water based corrosion synthesized by emulsion polymerization techniques and is during the synthesis process is introduced nanotube loading of titanium dioxide, which allowing the dispersion in the polymer matrix. Polymer dispersions obtained in this way are used as anti-corrosion coatings 100% water based.

  • Patent number: 9339577
    Abstract: An emanator device for emanating an air treatment agent into the surrounding air comprises a housing (102) which contains a solid or liquid source of the air treatment agent, wherein the housing comprises a blister or capsule containing an air treatment agent (108) and a plurality of openings which are sufficiently small that they can be closed by a film or plug of water. For example the openings may be provided by a gauze or mesh (114). The openings do not inhibit the emanation of air treatment agent released from the blister, but when the emanator device is subject to wet conditions, as may happen in a dishwashing machine, the openings are blocked by a film or plug of water. The air treatment agent does not therefore enter the water, where it may have caused adverse effects, or simply have been wasted. Under dry conditions, however, emanation occurs normally.
