  2. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    Electromagnetic shielding is the process of lowering the electromagnetic field in an area by barricading it with conductive or magnetic material. Copper is used for radio frequency (RF) shielding because it absorbs radio and other electromagnetic waves. Properly designed and constructed RF shielding enclosures satisfy most RF shielding needs ...

  5. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    Cathodic protection ( CP; / kæˈθɒdɪk / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead ...

    Ivory, exotic woods and metal were used as inlay or even as the entire foot on the best constructions, bringing artistic design to a commonplace object. [citation needed] In hot climates, ventilation through the woven bed base helps keep the sleeper cool, and the bed base is sufficiently flexible not to need padding. [5]

  7. Fuze - Wikipedia

    en.wikipedia.org/wiki/Fuze

    Rifled guns introduced a tight fit between shell and barrel and hence could no longer rely on the flame from the propellant to initiate the timer. The new metal fuzes typically use the shock of firing ("setback") and/or the projectiles's rotation to "arm" the fuze and initiate the timer : hence introducing a safety factor previously absent.
