  • Clinical thermometer opening apparatus and method
    Patent number: 3977856
    Abstract: A method and apparatus for making a controlled opening or bubble in the bore of a glass clinical thermometer comprises directing a narrow light beam at the heated glass while introducing pressurized fluid into the bore. The light beam is chosen to form a diffraction pattern including a shaprly imaged area whose width corresponds to the bore diameter. The diffraction image area width is used to obtain the desired bubble dimensions.

  • Automatic thermometer calibration system
    Patent number: RE28954
    Abstract: A system for automatically calibrating and classifying measuring instruments such as mercury clinical thermometers, by accurately determining the distance between two reference points established by two known reference parameters. The detection of the reference points is made by scanning a laser beam over the mercury column and detecting the change in the reflection characteristic of the beam at the upper level of the column.
