  • Indicating devices based on lateral diffusion of a mobile phase through a non-porous stationary phase
    Patent number: 10451595
    Abstract: This invention relates to indicating devices, such as time-temperature indicators based on lateral diffusion of a vapor of a solid and/or liquid mobile phase (e.g., a sublimeable dye or an activator) through a non-porous stationary phase, such as a thin layer of a polymeric material. The lateral diffusion of the mobile phase creates a noticeable boundary in the stationary phase whose movement depends upon processes, such as time and temperature.
    Type: Grant

    Date of Patent: October 22, 2019
    Assignee: JP LABORATORIES, INC

  • TIME INDICATING DEVICES BASED ON COUNTERBALANCING REACTIONS
    Publication number: 20160161919
    Abstract: Indicating devices based on the counter balancing effect of one parameter with that of others are disclosed. Color changing and self-reading indicating devices, such as a time indicator having essentially no effect of temperature are developed by this method. In diffusion based time-temperature indicating devices, the effect of temperature is lowered by crosslinking the medium of the device. The devices have net activation energy near zero kcal/mole.
