  • Thermal sensor for detection of potential mechanical failures and transmission of temperature warning signals
    Patent number: 5438322
    Abstract: A frequency generating circuit and a cap-freeing mechanism in a bolt are responsive to a longitudinal movement of a piston in response to overheating of an associated bearing. The cap-freeing mechanism transfers a force from the piston to a cap, thereby freeing the cap from a head portion of the bolt and allowing an antenna to extend to the outside of the bolt. The frequency generating circuit is activated by a connection made between a switch and a battery of the circuit by the piston. Upon becoming activated, the frequency generating circuit sends a predetermined frequency or frequency pattern through the antenna.
