  2. Fernico - Wikipedia

    en.wikipedia.org/wiki/Fernico

    FerNiCo I has the same linear coefficient of expansion as certain types of borosilicate ("hard" glass), (c6.5 × 10 −6 K −1, thus serving as an ideal material for the lead-out wires or other seal structures in light bulbs and thermionic valves. Dumet is also used for this purpose, but for passing through softer soda-lime and lead-alkali ...

    en.wikipedia.org/wiki/Glass-to-metal_seal

    Dumet-wire is a copper clad wire (25% of copper by weight) with a core of nickel-iron alloy 42 (42% of nickel by weight). [10] The core having low CTE makes it possible to produce a wire with a radial CTE lower than a linear CTE of the glass, so that the glass-to-metal interface is under a low compression stress.

    A number of units were used to measure length. One pied (1 fuss) was equal to 0.30 m, according to the fixed value defined during the transition to the metric system. [1] [4] Some other units and their fixed values are given below: 1 ligne = 1/144 pied 1 linie = 1/144 pied 1 pouce = 1/12 pied 1 zoll = 1/12 pied 1 aune = 2 pied (or 4 pied [3])
