Publication number: 20090123332Abstract: A sterilizable pouch having both internal and external sterilization record indicators to indicate whether attempted steam sterilization of the pouch and contents was successful or unsuccessful. The pouch preferably has one indicium in each indicator responsive to multi-parameter sterilization by steam, and another indicium in each indicator responsive to gas sterilization, such as using ethylene oxide.Type: ApplicationFiled: January 9, 2009Publication date: May 14, 2009Applicant: Crosstex International, Inc.Inventors: Andrew G. WHITEHEAD, Mitchell V. Steinberg, Charles A. Hughes

Patent number: 7514262Abstract: A device and method for monitoring the expiration of goods includes a substrate, a coating of polydiacetylene, said coating having properties of (1) changing from a first color irreversibly to a second color immediately upon being subjected to a specified temperature and (2), upon activation upon contact by an activating agent, changing from said first color to said second color at a temperature lower than said specified temperature after a time delay of at least one hour and an activating agent on a portion but not all of said coating.Type: GrantFiled: September 2, 2004Date of Patent: April 7, 2009Assignee: CMC Daymark CorporationInventor: Hans O. Ribi

Publication number: 20090028753Abstract: A sterilization challenge specimen holder is used with a test indicator to challenge sterilization on a consistent basis. The holder includes a body having an internal chamber region. A cap is sealable on the holder. An opening is defined in the body or cap that forms a single tortuous ingress and egress path communicating the interior chamber with the environs. An insulating layer is disposed over the body and cap to fully insulate the body and cap other than over the opening so as to not interfere with the ingress and egress path. The insulating layer reduces the heat transference from the environs to the interior chamber region.Type: ApplicationFiled: October 17, 2007Publication date: January 29, 2009Applicant: DANA PRODUCTS, INC.Inventor: Harry Bala

Patent number: 7481975Abstract: The present invention provides a hydrogen peroxide indicator that includes a substrate on which is disposed an indicator composition that includes at least one of a select group of colorants. As a result of contact with hydrogen peroxide, the colorants change color, and even become colorless, thereby providing an indication of the presence of hydrogen peroxide.Type: GrantFiled: July 14, 2004Date of Patent: January 27, 2009Assignee: 3M Innovative Properties CompanyInventor: David M.

Patent number: 7442552Abstract: A test environment and an associated method of testing and analyzing a semiconductor package material containing a molding compound, for stability in a sustained oxygen environment. Test samples are exposed to a pressurized gas containing oxygen, under elevated temperature below the glass transition temperature of the molding compound. Control samples are exposed to a pressurized inert gas under similar or more severe conditions of gas pressure, temperature, and humidity. At least one characteristic common to the test samples and the control samples is measured. A determination is made as to whether there exists at least one significant difference between the at least one measured characteristic of the test samples and the control samples.Type: GrantFiled: September 26, 2007Date of Patent: October 28, 2008Assignee: International Business Machines CorporationInventors: Joseph K. V. Comeau, Adele M. Mahoney, Jason P. Ritter, Gerald J. Scilla, Charles H. Wilson

Patent number: 7435981Abstract: A plurality of vessel holder means 14 are mounted around a revolving body 12 at an equal circumferential spacing. Each vessel holder means 14 includes two holders 26, 26 for carrying two vessels 4, 4 in vertical alignment. A path along which the revolving body 12 revolves contains an inversion interval C-D and an upright transfer interval D-B and A-C. Inversion means 16 which inverts the vessel holder means 14 about a tangential axis O1 is located within the inversion interval C-D while an electron beam irradiator 24 is located within the upright transfer interval A-C. Vessels which are fed at a vessel feed position A and carried by the holders 26 are subject to the irradiation of the electron beam at an electron beam irradiation position E, then inverted, and when it reaches the electron beam irradiation position E again, the opposite surface is subject to the irradiation of the electron beam. Vessels 4 are inverted again and then discharged at a vessel discharge position B.Type: GrantFiled: June 9, 2006Date of Patent: October 14, 2008Assignee: Shibuya Kogyo Co., Ltd.Inventors: Toshiaki Naka, Yukinobu Nishino
