  • Patent number: 7824556
    Abstract: Chlorous acid is generated from a chlorite salt precursor, a chlorate salt precursor, or a combination of both by ion exchange. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing unwanted cations from solution and adding hydrogen ion to solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequent to the generation of chlorous acid or simultaneously with the generation of chlorous acid. For catalysis of chlorous acid to chlorine dioxide, the chlorous acid may be generated by ion exchange or in a conventional manner. Ion exchange materials are also used to purify the chlorous acid and chlorine dioxide solutions, without causing degradation of said solutions, to exchange undesirable ions in the chlorous acid and chlorine dioxide solutions with desirable ions, such as stabilizing ions, and to adjust the pH of chlorous acid and chlorine dioxide solutions.

In order to be sterilized effectively by EtO gas, the devices are constructed such that surfaces not readily infused with EtO gas are made to be gas permeable, and will not retain the gas after the sterilization process. Performance qualification of the sterilization process is performed through physical and microbiological studies, and set of established physical process parameters. Maintaining the physical process parameters in subsequent sterilization cycles will consistently yield the desired sterility assurance level without having to test the devices for sterility.

  • Patent number: 7524434
    Abstract: Methods of treating aqueous coolants in open circulating water cooling tower systems are provided. The methods including placing a controlled release additive composition in contact with an open circulating aqueous coolant in an open circulating water cooling tower system. The controlled release additive composition includes a core having at least one additive selected from corrosion inhibitors and scale inhibitors; and a coating, for example, a polymeric coating, substantially surrounding the core. The coating is substantially insoluble in the aqueous coolant, and is effective to slow the release of the at least one additive into the aqueous coolant.

  • Patent number: 7445759
    Abstract: A system and method for extracting active elemental iodine from the contact of water with stored crystal iodine and for introducing the extracted elemental iodine into a water supply line and/or otherwise making the extracted elemental iodine available for an intended use. The system operates by allowing a portion of the water entering from a water supply line to be redirected to a first housing where it makes contact with stored crystal iodine causing to extract active elemental iodine. The iodinized water leaves the first housing and enters a second housing where it makes contact additional stored crystal iodine to help stabilize the elemental iodine concentration. The system can be designed to provide the elemental iodine in more than one potency concentration through the use of a metering valve and different travel routes for the elemental iodine out of the second housing.

  • Patent number: 7435378
    Abstract: The present invention is directed to a method and apparatus for treating goods, such as, for example, fumigating and re-cooling perishable goods, such as fruit, using a tarp and floor seal. The apparatus encloses goods on a surface and includes a canopy that is substantially impermeable to flowable materials, such as gas, liquid, or a combination thereof; an upper perimeter for supporting an upper portion of the canopy; a lower perimeter for supporting a lower portion of the canopy, the lower perimeter to be placed in proximity to the surface; a support structure for supporting the upper perimeter and lower perimeters; and a gasket in communication with the lower perimeter, wherein the gasket is deformable to substantially seal the chamber by compressing the gasket against the surface. The apparatus may also include an intermediate support structure for providing support to the canopy and a conduit in communication with the chamber to supply cool air to the chamber.

  • Patent number: 7431900
    Abstract: A hydrogen peroxide vapor generation unit (10) receives hydrogen peroxide and water solution at an interface (20) and interconnects with an air dryer (14) by way of nipples (72, 92). In one embodiment, the dryer includes a clamping assembly (42) which is latched (74, 94) with the nipples and which receives a disposable desiccant cartridge (40). In an alternate embodiment, a reusable desiccant cartridge (40?) is connected directly to the nipples (72, 92). When the desiccant cartridge (40?) is saturated, it is removed and placed in a regenerator unit (120). A regenerated cartridge is installed in its place.

    Abstract: Disclosed is a composition of matter comprising a defined dispersion of lactoferria immobilized on a naturally occuring substrate via the N-terminus region of the lactoferrin. Compositions comprising immobilized lactoferrin (Im-LF) are used in a method for reducing the microbial contamination of a composition subject to microbial contamination, which is also disclosed, and which encompasses a method for reducing the microbial contamination of a foodstuff, such as a meat product. Foodstuffs treated by the method are disclosed, including meat products. A method of inhibiting the growth and/or adhesion of a microbial species on a food-contacting surface f a material for food packaging or food handling with Im-LF is also disclosed. Food containers and food-handling implements so treated are also disclosed, as are antimicrobial cleansers, polishes, paints, sprays, soaps, or detergents containing Im-LF for applying to an inanimate surface.

    Abstract: A vehicle HVAC system includes a HVAC components such as a duct, vent, manually adjustable airflow control head, toggle or housing manufactured from a molded plastic material having an antimicrobial additive. The antimicrobial additive is preferably introduced as an additive during molding of the HVAC components that are typically injection or blow molded parts. Usage of a plastic having an antimicrobial additive continuously fights the growth of microbes such as most common bacteria, yeasts, molds and fungi that cause stains, odors and product degradation that can cause stains, odors and product degradation. The antimicrobial additive becomes an integral part of the HVAC components and therefore is maintenance free.

  • Patent number: 7354551
    Abstract: A system for microbially and/or chemically decontaminating a room such as a hotel room includes a vapor generator which supplies a decontaminant vapor, such as hydrogen peroxide vapor to the room. The room is then aerated to a level at which it is safe for normal occupants to enter. By using a two step aeration, with a second step at lower humidity than the first, the concentration of residual hydrogen peroxide is reduced rapidly to safe levels of 1 ppm or less, typically about 0.5 ppm, in under four hours. The room is rendered substantially free of contaminants, such as those responsible for Severe Acute Respiratory Syndrome (SARS), Norwalk virus, and unpleasant odors.

  • Patent number: 7351373
    Abstract: The invention relates to the oxidative treatment of bulk material in a vessel. The bulk material to be treated is placed in the vessel, and is humidified therein with water or an aqueous solution to such an extent that it can be treated with an O2/O3 gas mixture in such a way that the desired end product has a determined pH value or a determined solubility or a determined polarity or a determined solubility behaviour and/or particle size distribution. The inventive method enables bulk material to be very effectively oxidised by means of minimal amounts of ozone in an O2/O3 gas mixture, in such a way that between 70 and 100% of the ozone parts enter into a reaction.
