  • Crucible with differentially expanding release mechanism
    Patent number: 6176923
    Abstract: A crucible is held in a closed position when the crucible is at a certain temperature. A temperature sensitive member expands differently in response to heat than other portions of the crucible. When the temperature of the temperature sensitive member is increased, the temperature sensitive member expands an amount different than do other portions of the crucible and thereby causes the crucible to open.
