Abstract: The present invention provides a hydrogen peroxide indicator and a peracetic acid indicator that include a substrate on which is disposed an indicator composition that includes at least one of a select group of colorants and a transition metal salt. As a result of exposure to hydrogen peroxide and/or peracetic acid, the colorants change color, and even become colorless, thereby providing an indication of the presence of hydrogen peroxide and/or peracetic acid.

Abstract: A publication can be received in electronic form and then selected portions clipped with a software editing tool for pasting into a customer's web box. The customer may then view the clipped portion at their leisure. The electronic form of the publication may be created by scanning in the publication. Selected portion can be advertisements and thus provide to the customer as tear sheets. Selected portions can also be searched for using a query to provide an ability to quickly find news clippings desired by the customer.

Abstract: A steam sterilization indicator composition comprising a bismuth compound, a sulfur source, and a compound capable of generating alkaline conditions when exposed to steam; wherein when exposed to steam the composition noticeably changes color and when exposed to dry heat either does not change color or changes color to one that is markedly different from the color formed when the same composition is exposed to steam.

Abstract: Indicators for the steam-formaldehyde sterilization process are provided which undergo a color change when placed in a steam-formaldehyde environment.
