Abstract: In an apparatus for evaporation and vacuum deposition of metal on an article to be coated therewith, spaced-apart electrical binding posts are located within a vacuum chamber. The ends of an electrical self-resistance-heated evaporation boat are clamped to the binding posts. The end portions of the boat have a lower electrical resistivity than the center portion in order to minimize contact resistance and to reduce power dissipation at the ends of the boats.

Abstract: A tungsten wire, previously drawn to a predetermined diameter, is stretched at a stress between its elastic limit and about 95 percent of its ultimate tensile strength, thereby imparting a permanent elongation to the wire. The stressed wire is then coiled into filaments which, on recrystallization, have improved nonsag properties.
Abstract translation: 预先拉制成预定直径的钨丝在其弹性极限和其极限拉伸强度的约95％之间的应力下被拉伸，由此赋予线永久伸长。 然后将应力线卷成长丝，其在重结晶时具有改善的不合格特性。
