    Abstract: An assembly and method for treating or otherwise improving an atmosphere contained within an enclosed space. The enclosed space can be a container such as a bag or other housing for equipment, food and/or suitable material, or a room, another similar space and/or environment within a residential building space, a commercial building space, an industrial building space and/or a space of any other similar building structure. Ozone is generated within an atmosphere that is exposed to the material. The generated ozone is mixed with the atmosphere in the presence of UV light. The ozone reacts with contaminants in the presence of UV light and removes or inactivates those contaminants from the atmosphere. The UV light and ozone inactivate microbes and alter the proteins on allergens. At least a portion of the generated ozone is then removed from the mixed atmosphere.

    Abstract: An air decontamination device comprises an air stream generator (20), a nonthermal plasma filter (22), an ultraviolet radiation emitting device (24), an ozone catalysing device (26), and a hydrocarbon emitter (28). The air stream generator (20) generates and directs an air stream through or across the non-thermal plasma filter (22), the UV radiation emitting device (24), the ozone catalysing device (26), and the hydrocarbon emitter (28). The plasma filter (22) produces free radicals by which contaminants in the air stream are neutralised. The UV radiation emitting device (24) beaks down ozone in the air stream, catalysed by the ozone catalysing device (26). The hydrocarbon emitter (28) discharges an aromatic hydrocarbon into the air stream to preferentially react with residual ozone so that the air stream becomes suitable for human exposure.

    Abstract: The Diffusive Plasma is for effective treatment of contaminated air and material processing. Air is purified and disinfected by passing through the diffusive plasma device which includes a reactor or a plurality of reactors arranged in parallel or series and is energized by a high voltage alternating current power supply. The diffuser, being electrically isolated, provides extra nucleation sites to initiate discharges. It serves to improve the generation of uniform and consistent plasma and to reduce the variation of discharge properties among the reactors. The addition of a diffuser, thereby, enhances the overall effectiveness of decomposing chemicals and destroying microbes to achieve high air treatment and material processing performance. The diffuser can be made of suitable filtering materials to additionally serve as a filter.

  • Patent number: 6451270
    Abstract: The present invention is a brine-maker of a two-tank arrangement specifically designed for efficient removal of salt sludge. The first tank is a salt-hopper into which water flows from the bottom and up through salt to form brine and leaves mineral impurities called sludge on the bottom of the hopper. The brine then overflows through strainers into a brine containment tank. The outside of the salt hopper has bracketing means attached. When the sludge needs to be removed, a lifting device is attached to the bracketing means and the hopper is disconnected from the water supply by a quick-fit coupler and removed to a dumping site where it is turned on its side and the sludge is poured out. The salt hopper is then returned to its position and coupled to the water supply. The salinity level of the brine in the containment tank can be adjusted either by adding fresh water or by running the brine back through the salt in the salt hopper. The brine is stored in the brine containment tank until discharged for use.

  • Patent number: 6406665
    Abstract: An apparatus is described for disinfecting and testing the electrical safety of a transesophageal echo—TEE-probe. The apparatus comprises a receptacle adapted to receive the TEE-probe, apparatus for supplying the receptacle with a disinfection fluid and with a rinsing fluid, apparatus for removing any fluid from the receptacle, and an insulation tester having a first contact within the receptacle and a second contact connectable with the TEE-probe. The disinfecting and testing of the electrical safety is executed by supplying the receptacle with a disinfection fluid, disinfecting the TEE-probe, and removing the disinfection fluid. The receptacle is then supplied with a rinsing fluid and the TEE-probe is rinsed from remaining disinfection fluid. When the TEE-probe has been rinsed and before removing the rinsing fluid from the receptacle, an electrical safety test is executed with the TEE-probe by using the rinsing fluid.

  • Patent number: 6387332
    Abstract: A safety system for a gas process or facility for measuring the concentration of a specified gas in an area or chamber and determining whether it is safe to allow access to such area or chamber. In particular, the safety system is adapted for use in a gas sterilization facility having one or more sterilization chambers, wherein the safety system measures the concentration of the sterilizing gas and unlocks the door of the sterilization chamber if the level of the sterilizing gas in the sterilization chamber is below a predetermined limit. The safety system further limits access to the sterilization chamber after a predetermined period of time if the door of the sterilization chamber is not opened due to the possible continued desorption of the sterilizing gas from the articles into the sterilization chamber.

  • Patent number: 6290906
    Abstract: A method of removing sterilization gas from a load disposed in a chamber. In accordance with the method, the chamber is evacuated to a subatmospheric pressure. A diffusion gas comprising helium is provided. An amount of the diffusion gas is introduced into the chamber effective to create a superatmospheric diffusion pressure in the chamber. The diffusion gas is allowed to diffuse throughout the chamber to displace sterilization gas from the load. The chamber is evacuated to remove portions of the diffusion gas and the sterilization gas from the chamber.

  • Patent number: 6136267
    Abstract: A fuel ignition arrester system that has a feedback control to maintain the fuel/air mixture in the ullage of a fuel tank above the flammability range. The system uses a photoelectric detector to signal when the fuel/air mixture concentration falls or rises to a predetermined concentration value. The predetermined value is selected to be higher than the upper limit of the flammability range so that the fuel/air mixture is maintained above the range and, thus, incombustible. A fuel pump and piping system with nozzles is arranged to inject fuel into the ullage when the concentration falls to the predetermined value and to stop injecting fuel when the concentration rises to the predetermined value. A flammability detection system includes the detector and a controller that produces an annunciating signal when the fuel/air mixture concentration is equal to or between the upper and lower limits of the flammability range.

  • Patent number: 6019940
    Abstract: An improved method for processing an industrial sterilization agent utilized to sterilize medical instruments includes the use of a regenerative thermal oxidizer. The sterilization agent is removed from the sterilization chamber and directed into the combustion chamber with little chance for the sterilization agent to mix with air or any other source of oxygen. In this way, the present invention reduces the possibility of explosion of the sterilization agent prior to its being directed into the combustion chamber.

  • Patent number: 5891390
    Abstract: A novel apparatus and method for sterilizing microbially contaminated materials, e.g., hospital linens, packaged goods, etc., by contact with a flammable chemical sterilant gas such as ethylene oxide, employs a bulk supply vessel for the sterilant gas and a small unit dosage vessel which receives a unit dosage of sterilant gas from the bulk supply vessel. The unit dosage vessel delivers a charge of sterilant gas to a separately enclosed sterilizing chamber in which the materials to be sterilized are placed. Water flooding means in a supply cabinet in which the bulk supply vessel is positioned, protects against possible deflagration of the sterilizing gas in the event of leakage or rupture of the gas supply means.

  • Patent number: 5837192
    Abstract: When reactors charged with nitrogen as inert-blanketing gas are opened, high losses of inert-blanketing gas occur which previously have only been able to be compensated for by increased feed of inert-blanketing gas. To minimize the consumption of inert-blanketing gas during temporary opening of reactors (1), a further inert-blanketing gas is admixed to the nitrogen. The inert-blanketing gas mixture in the process has a density which is slightly greater than the density of the surrounding air.
