    • A temperature indicator having a tubular structure; a float or floating particles releasably held in place in the tubular structure by a temperature dependent material that is activated at or about a critical temperature, the float or floating particles having a first density; and a fluid within the tubular structure, the fluid having a second density that is less than the first density. When the temperature indicator is heated to the critical temperature, the temperature dependent material activates and releases the float or the floating particles, which rise in the fluid so as to be visible as in indicator that the critical temperature has been reached.
    • 具有管状结构的温度指示器; 漂浮或浮动颗粒通过温度依赖性材料可释放地保持在管状结构中,温度依赖性材料在临界温度或临界温度附近被激活,浮子或浮动颗粒具有第一密度; 以及所述管状结构内的流体,所述流体具有小于所述第一密度的第二密度。 当温度指示器被加热到​​临界温度时,依赖温度的材料激活并释放浮子或浮动颗粒,浮动颗粒在流体中升高,以便在达到临界温度的指示器中可见。

    • A transparent vacuum formed vessel 1 is filled with a liquid 3 at room temperature that will become a solid at freezing temperature and a low density float material 4. After freezing, the vessel is turned upside down so that upon thawing, the vivid colored float will move to the top of the vessel showing a thaw. The devise can be reused.The same concept can be used as a cooking aid by using a transparent sealed tubular 1 assembly inserted in the food with a solid cylinder 3 that will melt at some critical temperature allowing the low density float to rise to the top of the indicator visibly protruding from the food. More than one meltable cylinder, 3 & 8 and float, 4 & 5 may be used as a warning and ready indicator.Combinations of solid dense particulates and low density materials may also be used for color changing indicators. A permanent magnet attached to a float can be used to trigger an audible alarm, which can be incorporated in various cooking utensils to show cooking temperatures and times.
    • 透明真空成型容器1在室温下填充液体3,在冷冻温度下将成为固体,而低密度浮质材料4。 冷冻后,将容器倒置,以便在解冻时,生动的彩色浮子将移动到容器顶部,显示出融化作用。 设计可以重复使用。 通过使用插入在食物中的透明的密封管状组件1可以将相同的概念用作烹饪辅助装置,其中固体圆筒3将在某些临界温度下熔化,从而允许低密度浮子上升到指示器的顶部, 食物。 可以使用多个可熔缸,3&8和浮子,4和5可以作为警告和就绪指示器。 固体致密颗粒和低密度材料的组合也可用于变色指示剂。 附着在浮子上的永久磁铁可以用于触发一个可听见的报警器,可以将其并入各种烹饪用具中,以显示烹饪温度和时间。

    • A simple recording device using a stable electric resistance heater in thermal contact with an irreversible color changing time temperature material relatively insensitive to room temperatures to show and record the cumulative time an electrical appliance, battery, tool, instrument has been used.The device may use a plurality of thick film carbon printed resistive heater with a thermal gradient in contact with the time temperature material or a simple adhesive calibrated time temperature film on a surface mounted stable resistor. The indicator is in parallel or series with the power switch.The time temperature material is in thermal contact with a constant temperature heater when used in fluctuating ambient temperature conditions.
