  • Patent number: 4229973
    Abstract: A device for braking the motion of the float of a float type liquid-level gauge used with a liquid container, comprising a casing, a vane member disposed in the casing in such a manner as to produce a motion relative to the casing, a fluid placed to fill the inner space of the casing now containing the vane member and retaining an extra space for permitting the relative motion of the vane member, and a path formed in the casing to permit flow of the fluid inside the inner space of the casing during the aforementioned relative motion of the vane member inside the casing. In actual use, the casing is fixed in position and the vane member is connected with a member adapted to move in conjunction with the float of the float type liquid-level gauge. When a sudden, momentary displacement occurs in the liquid level in the liquid container with which the liquid-level gauge is used, the float kept on the liquid surface by buoyant force tends to follow the displacement.

  • Patent number: 4210893
    Abstract: A thermal cut-off fuse comprises a housing, a pair of terminals opposed to each other within the housing, a sliding means constantly urged by a spring, a thermal pellet adapted to melt at a fixed elevated temperature and remain in a solid state at normal room temperature and, by virtue of the solid state, restrain the sliding means from the forward motion imparted thereto by the spring and consequently serve to form a continuous space between the pair of terminals, and a conductive material disposed within the space to establish electric continuity between the terminals. When the ambient temperature is elevated to reach the fixed level, the thermal pellet melts, to release the sliding means and allow it to move under the force of the spring into a position where it severs the continuous space and consequently breaks the electric continuity between the two terminals.

  • Patent number: 4208647
    Abstract: A thermal switch for automatically opening a circuit when the ambient temperature exceeds a predetermined level is disclosed which utilizes a sensing pellet formed of an organic-glass bead mixture. The organic-glass bead pellet retains a pair of leads in contact with each other when the ambient temperature is below the melting temperature of the organic material. The addition of the glass beads to the temperature sensing pellet allows the compressive strength that is needed to hold the leads together to be more reliably controlled. In the process of combining the organic material and the glass beads, to form the pellet, the organic material is first melted so as to flow around the beads. Manufacture of the thermal-sensing pellet in this manner eliminates the voids which occur in the pressed organic pellets that are conventionally used in thermal sensing devices.
