  2. Aircraft tire - Wikipedia

    en.wikipedia.org/wiki/Aircraft_tire

    Aircraft tire tread patterns are designed to facilitate stability in high crosswind conditions, to channel water away to prevent hydroplaning, and for braking effect. Aircraft tires also include fusible plugs (which are assembled on the inside of the wheels), designed to melt at a certain temperature.

  4. Fusible plug - Wikipedia

    en.wikipedia.org/wiki/Fusible_plug

    A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel. In steam boilers the fusible plug is screwed into the crown sheet (the top plate) of the firebox, typically extending about 1 in (25 mm) into the water space above it. Its purpose is to act as a last-resort ...

    A set of pole-top fusible cutouts with one fuse blown, protecting a transformer - the white tube on the left is hanging down Fuses are used on power systems up to 115,000 volts AC. High-voltage fuses are used to protect instrument transformers used for electricity metering, or for small power transformers where the expense of a circuit breaker ...

  6. Fusible link - Wikipedia

    en.wikipedia.org/wiki/Fusible_link

    An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect AWG 12 wiring.

  7. Core (manufacturing) - Wikipedia

    en.wikipedia.org/wiki/Core_(manufacturing)

    Cores are used for complex injection moldings in the fusible core injection molding process. First, a core is made from a fusible alloy or low melting temperature polymer. It is then placed inside the injection mold's dies and the plastic is shot into the mold. The molding is then removed from the mold with the core still in it.

  8. Fusible core injection molding - Wikipedia

    en.wikipedia.org/wiki/Fusible_core_injection_molding

    The fusible core process finds application, for example, for injection molded passenger car engine intake manifolds. By modifying the equipment, small molded parts like valves or pump housings can be manufactured, as the manufacture of the fusible cores and the injected parts can be carried out on an injection molding machine.
