Patent number: 5964181Abstract: A critical temperature indicating device is provided. It includes a microporous membrane, an indicating composition containing less than about 10 wt-% water, and means for containing the microporous membrane and the indicating composition. The indicating composition includes: a primary organic component comprising at least one compound that has a freezing point above the critical temperature and does not spontaneously wet out the microporous membrane at a temperature at least about 30.degree. C. above the critical temperature; a modifying component comprising at least one compound that has a freezing point below the critical temperature; and a wetting component comprising at least one compound that has a freezing point below the critical temperature and is capable of spontaneously wetting out the microporous membrane at about the critical temperature.Type: GrantFiled: November 16, 1995Date of Patent: October 12, 1999Assignee: 3M Innovative Properties CompanyInventors: Rodger J.

Patent number: 5667303Abstract: A selectively activated time-temperature integrating device for providing a visually observable indication of cumulative thermal exposure, in which a viscoelastic material migrates into a diffusely light-reflective porous matrix at a rate which varies with temperature to progressively change the light transmissivity of the porous matrix and thereby provide the visually observable indication. The viscoelastic material can comprise a pressure sensitive adhesive. The visually observable indication can comprise latent indicia which initially are not visible and become visible, obscurable indicia which initially are visible and become obscured, or a combination of both. Various actuating means for selectively switching the indicator from an unactivated state to an activated state are described.Type: GrantFiled: March 10, 1995Date of Patent: September 16, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert P. Arens, Russell D. Birkholz, Dee Lynn Johnson, Theodore P. Labuza, Curtis L. Larson, David J. Yarusso
