  3. Induction sealing - Wikipedia

    en.wikipedia.org/wiki/Induction_sealing

    Induction sealing also offers advantages when sealing to glass: Using a conduction sealer to seal a simple foil structure to glass gives no tolerance or compressibility to allow for any irregularity in the glass surface finish. With an induction sealer, the contact face can be of a compressible material, ensuring a perfect bond each time.

    External vacuum sealers involve a bag being attached to the vacuum-sealing machine externally. The machine will remove the air and seal the bag, which is all done outside the machine. A heat sealer is often used to seal the pack. Typically these units use a dry piston vacuum pump which is often considered a "maintenance-free" pump.

    The IFEX handheld impulse gun. The Impulse Fire Extinguishing System (abbreviated IFFS) is a series of firefighting equipment that uses small amounts of water fired in high-velocity bursts to put out fires. Water droplets are shot in vaporous bursts that can travel up to 120 metres per second (390 ft/s) and provide a large surface area for cooling.

  9. Dielectric withstand test - Wikipedia

    en.wikipedia.org/wiki/Dielectric_withstand_test

    An insulation test set; in this pattern, a hand-cranked generator provides the high voltage and the scale is directly calibrated in megohms. Voltage withstand testing is done with a high-voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test.
