  • Patent number: 8439563
    Abstract: The gas-actuated thermometer is formed as a unitary, monolithic glass structure with a gas bulb at one end and an indicator tube extending therefrom. The bulb and tube are permanently and hermetically sealed to contain the actuating gas therein. A closed cell foam indicator resides in the indicator tube. The indicator travels along the tube in accordance with the expansion and contraction of the gas within the bulb and adjacent portion of the tube. A second gas or mechanical spring is provided in the opposite end of the tube to balance the pressure of the indicator gas. The indicator tube, and preferably also the bulb, are flattened to an elliptical or similar cross-sectional shape. This facilitates the fit of the device for use as an oral medical thermometer, and the wider cross section enables both Celsius and Fahrenheit temperature scales to be marked along the indicator tube.

  • Patent number: 7097353
    Abstract: Disclosed is a temperature indicating method and device. The device embodies a sealed tube containing a liquid and a float. The tube has markings on the exterior indicating temperature zones or, in the alternative, temperature gradients. The method disclosed includes inverting the tube such that the indicator drops to the bottom of the tube and freezing the device at the appropriate temperature level. In use, the device is placed right side up in a container along with other items for which the highest temperature level arrived at is desired to be known. Upon warming, the liquid in the tube melts and the float drops through the liquid to the freezing level of the liquid. By removing the device from the container and comparing the float level in the tube to the markings on the exterior of the tube, the highest temperature or temperature zone that the contents of the container were subjected can be determined.
