Patent number: 7550122Abstract: A decontamination system for decontaminating an enclosure defining a chamber or region. The decontamination system includes an air bypass for introducing atmospheric air into the decontamination system and bypassing air to the atmosphere in response to system operating conditions. The air bypass allows increased airflow through the decontamination system during certain operating modes of the decontamination system (i.e., dehumidification and aeration phases), thereby reducing the amount of time needed to dehumidify and aerate the enclosure. The air bypass also facilitates the use of a high capacity dryer in the decontamination system.Type: GrantFiled: May 31, 2006Date of Patent: June 23, 2009Assignee: American Sterilizer CompanyInventors: Peter J.

Patent number: 7361317Abstract: Disclosed herein is a single step sterilization wrapping material suitable for use, as an example, in wrapping surgical instruments and supplies for sterilization, transportation and storage. The material includes separate inner and outer wraps which, unlike previous wraps, are joined to one another. Common wrapping techniques involve wrapping items to be sterilized with two separate sheets of wrap. The present invention provides separate wraps which can be specially engineered to deliver specific properties for each sheet and then joined to one another so as to permit wrapping and opening in a neat single step process which increases efficiency and saves time and money. In special situations the outer wrap can be engineered with increased strength, the inner wrap with increased barrier properties and the inner and outer wraps can be made visually distinct from one another so that improper wrapping or opening is not a problem.Type: GrantFiled: April 19, 2002Date of Patent: April 22, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sonya Nicholson Bourne, Nelson McRay, Lavada Campbell Boggs, William Ralph Neff, Charles John Morell, Marsha Lottie Vaughn

Patent number: 7311883Abstract: The system is based on a change in the intensity of evaporation caused by a chimney effect, modifying the flow of air that circulates through the environment apparatus in the surrounding area of the wick. It consists of using a casing (1) with slots (6) for the passage of air in its upper part. This is done in such a manner that said casing (1) can be used in isolation, thus attaining an apparatus that does not regulate the evaporation intensity, but that has a complementary part (7) joined to the upper part of said casing (1). This assembly, enabling free turning, has complementary slots (9), that determine a greater or lesser flow of air and the consequent regulation of the intensity of the evaporation, depending on the greater or lesser degree of opposition they have to the slots (6).Type: GrantFiled: January 29, 2001Date of Patent: December 25, 2007Assignee: DBK Espana, S. A.Inventor: Jordi Basagañas Millan

Patent number: 7300625Abstract: A chlorine gas generating candle in a vented container which serves as a portable means to generate heated chlorine gas for killing insects, bacteria, viruses and other dangerous biological agents. The device has application in sanitizing dwellings, swimming pools and the like, and is effective in case of accidental release and/or biological attack. The chlorine gas generating candle disinfects an enclosed space with a quantity of heated chlorine gas. The chlorine gas generator is a self contained unit including an igniter which can be activated to initiate a self propagating burn of the entire candle and a resultant distribution of toxic chlorine gas. The use of one or a plurality of chlorine generators described in this application can provide any desired concentration of the killing gas. The chlorine gas generating candle can be safely and easily transported and does not require a source of power to operate.Type: GrantFiled: March 18, 2004Date of Patent: November 27, 2007Assignee: The United States of America as represented by the Secretary of the NavyInventors: Vladimir Hlavacek, Carl Gotzmer

Patent number: 7294305Abstract: A method and an apparatus for sterilizing a lumen device. A lumen and a container having an interface on a wall of the container are enclosed in a chamber. The lumen is placed across the interface so that one end of the lumen is in the container and the other end is in the chamber. Germicide is introduced into the chamber, and a pressure difference is created between the two ends of the lumen, so that the germicide flows through the lumen. The lumen may alternatively be placed across an interface which separates the chamber into two areas. Germicide is introduced into the chamber, and a pressure difference is created between the two areas of the chamber, causing the germicide to flow through the lumen.Type: GrantFiled: April 29, 2005Date of Patent: November 13, 2007Assignee: Ethicon, Inc.Inventors: Szu-Min Lin, Paul Taylor Jacobs

Patent number: 7291314Abstract: An apparatus subjects water to waves from an RF plasma. This allows continuous production of “activated water” characterized by cluster sizes below about 4 molecules per cluster, water having pH below 4 or above 10, or water having ORP of less than ?350 mV or more than +800 mV. The basic frequency of the plasma is preferably between 0.44 MHz and 40.68 MHz, and the plasma is preferably modulated at a frequency between 10 kHz and 34 kHz. Flow rates typically range from 20 l/hr to about 2000 l/hr. Activated water can be used for many purposes, including antimicrobial cleaning of worktable, floor, wall, knife, transport and other surfaces, for example, in meat processing facilities and hospitals.Type: GrantFiled: December 20, 2001Date of Patent: November 6, 2007Assignee: Hydro Enterprises, Inc.Inventors: George Paskalov, Mark Gorodkin, Viktor Sokolov
