2. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   The first two or three digits of the number specify the tensile strength of the weld metal, in thousand pounds per square inch (ksi). The penultimate digit generally identifies the welding positions permissible with the electrode, typically using the values 1 (normally fast-freeze electrodes, implying all position welding) and 2 (normally fast ...

3. Fusible link - Wikipedia

   en.wikipedia.org/wiki/Fusible_link

   A mechanical fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is designed to melt at a specific temperature, thus allowing the two pieces to separate. Mechanical fusible links are utilized as the triggering device in fire sprinkler systems and mechanical automatic door release mechanisms ...

4. Stabilator - Wikipedia

   en.wikipedia.org/wiki/Stabilator

   Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).

5. Fuse cutout - Wikipedia

   en.wikipedia.org/wiki/Fuse_cutout

   The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes but a solid door will allow the full 300 ampere capacity of the cutout to be utilized.

6. 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 ...

7. Fusibility - Wikipedia

   en.wikipedia.org/wiki/Fusibility

   The most common test used to determine fusibility is to join two pieces with a variable heat source, increasing the temperature or power used in steps, and testing bond strength for each step. If there is no step with good bond strength after joining, then fusibility is said to be low.

8. Emulsion stabilization using polyelectrolytes - Wikipedia

   en.wikipedia.org/wiki/Emulsion_stabilization...

   The two main types of emulsions are oil-in-water (nonpolar in polar) and water-in-oil (polar in nonpolar). The difference depends upon the nature of the surfactant or polyelectrolyte in question. The hydrophilic pieces will attract the polar solvent, creating a water-in-oil emulsion and the hydrophobic pieces will attract the nonpolar solvent ...

9. Fuse (electrical) - Wikipedia

   en.wikipedia.org/wiki/Fuse_(electrical)

   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 ...
