422002000 | Step of warning or decreasing hazard of process | 7 |
20080213125 | Apparatus and Method for Using Ozone as a Disinfectant - A method of sterilizing a closed environment is provided in which an ozone generator is placed into the closed environment; it then generates ozone to a predetermined ozone concentration and increases the humidity of the closed environment. The ozone concentration is maintained at the predetermined ozone concentration for a predetermined period of time, and after the period of time has expired, the ozone is depleted. When the ozone concentration is reduced to a predetermined safe level, the ozone generator signals. | 09-04-2008 |
20080310992 | APPARATUS AND METHOD FOR USING OZONE AS A DISINFECTANT - A method of sterilizing a closed environment is provided in which a disinfection apparatus is placed into the closed environment; it then generates ozone to a predetermined ozone concentration, following which the humidity of the closed environment is rapidly increased. A catalytic converter then reduces the ozone concentration to safe levels. When the ozone concentration is reduced to a predetermined safe level, the disinfection apparatus signals. | 12-18-2008 |
20090004046 | Ceiling lighting fixture with UV-C air sterilization - An UV-C air sterilizer with an optional visible light provides effective air sterilization through the use of a relatively low intensity UV-C radiation field external of the fixture and the continuous circulation of a mixture of treated and untreated air. Methods are also disclosed. | 01-01-2009 |
20090208365 | APPARATUS AND METHOD FOR MAKING A PEROXYCARBOXYLIC ACID - The present invention relates to apparatus and methods for making a peroxycarboxylic acid. The apparatus includes a reaction catalyst and a guard column for pretreating one or more reagents, which can increase the life, activity, and/or safety of the reaction catalyst. The peroxycarboxylic acid compositions made by the method and apparatus can include one or more peroxycarboxylic acids. | 08-20-2009 |
20120020830 | Apparatus And Method For Using Ozone As A Disinfectant - A method of sterilizing a closed environment is provided in which an ozone generator is placed into the closed environment; it then generates ozone to a predetermined ozone concentration and increases the humidity of the closed environment. The ozone concentration is maintained at the predetermined ozone concentration for a predetermined period of time, and after the period of time has expired, the ozone is depleted. When the ozone concentration is reduced to a predetermined safe level, the ozone generator signals | 01-26-2012 |
20130287626 | APPARATUS AND METHOD FOR TREATING IMPURITIES IN AIR AND MATERIALS - 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. The assembly and method can be used to treat the air in a room, or to treat contaminated sports equipment and the like, as well as to treat food storage atmospheres, such as those exposed to fresh fruits and vegetables. | 10-31-2013 |
20150297765 | APPARATUS AND METHOD FOR STERILIZING CONTAINERS WITH X-RAY RADIATION MONITORING - An apparatus for sterilizing containers includes a transport device which transports the containers along a predefined transport path (P), a radiation device which applies radiation (S) to at least some sections of the containers and/or components of the apparatus for sterilization purposes, and a sensor device which detects radiation occurring as a result of the radiation (S) emitted by the radiation device. The apparatus has a shielding element which attenuates the radiation reaching the sensor device in a working mode of the apparatus, and a movement device for moving said shielding element relative to the sensor device. | 10-22-2015 |
