Publication number: 20060216496Abstract: Abstract of the Disclosure ABSTRACT OF THE DISCLOSURE Gas generating and releasing articles consisting essentially of a polymer and a gas generating solid dispersed therein are described. The article generates and releases a gas in response to moisture and in the absence of an acid, a polymer that degrades to produce an acid, a compound that generates an acid in response to humidity, a hygroscopic compound, and an oxidant. The article may also generate and release a gas in response to energy.Type: ApplicationFiled: November 13, 2003Publication date: September 28, 2006Applicant: Bernard Technologies, Inc.Inventors: Peter Gray, Michael Lelah, Peter Kwong

Publication number: 20060127273Abstract: A chlorine dioxide gas producing apparatus has a first reaction component contained therein and a second reaction component contained therein. The first and second reaction components are separated within the apparatus by at least one rupturable membrane. To activate the apparatus, the at least one rupturable membrane is ruptured to permit contact between the first and second reaction components to facilitate a chemical reaction therebetween which produces chlorine dioxide gas. The apparatus is adapted for releasing chlorine dioxide gas produced therein. The apparatus may be placed into an enclosure containing articles to be treated and the enclosure then closed to permit a concentration of chloride dioxide gas produced by the apparatus sufficient to treat the at least one article to fill the enclosure.Type: ApplicationFiled: February 3, 2006Publication date: June 15, 2006Applicant: Bernard Technologies, Inc.Inventor: Joel Kampa

Publication number: 20040241065Abstract: A chlorine dioxide gas generating kit includes a gas generating apparatus having a first reaction component contained therein and a second reaction component contained therein. The first and second reaction components are separated within the apparatus by at least one rupturable membrane. To activate the apparatus, the at least one rupturable membrane is ruptured to permit contact between the first and second reaction components to facilitate a chemical reaction therebetween which produces chlorine dioxide gas. The apparatus is adapted for releasing chlorine dioxide gas produced therein. To inhibit the unintended rupturing of the membrane, the kit also includes a substantially rigid receptacle defining an internal cavity sized and shaped for receiving at least a portion of the apparatus to inhibit flexing and bending of the apparatus. Before activating the apparatus, the apparatus is removed from the receptacle.Type: ApplicationFiled: March 31, 2004Publication date: December 2, 2004Applicant: BERNARD TECHNOLOGIES, INC.Inventors: Joel J. Kampa, Sumner A. Barenberg, Peter N. Gray

Patent number: 6767509Abstract: A sterilization system and process is provided which is useful in the chemical sterilization of medical supplies and equipment. The system includes a container having an internal generator of a sterilant such as chlorine dioxide. An internal container activator, such as high humidity or manual manipulation, is provided and stimulates the formation and release of the sterilant. The package includes a first indicator responsive to the release of sterilant and a second indicator which records the passage of a predetermined time interval. The combination of the sterilant indicator and the time interval indicator signals that proper sterilization conditions have been met and that the objects have been suitably sterilized.Type: GrantFiled: June 12, 2000Date of Patent: July 27, 2004Assignees: Kimberly-Clark Worldwide, Inc., Bernard Technologies, Inc.Inventors: Henry L. Griesbach, Peter N. Gray
