    摘要： An illuminator for use in a refractometer having a body housing, a sample cover assembly, a prism assembly and measuring assembly for measuring the composition and density of a substance. The illuminator includes a light source, a power source for operating the light source and an operating means for selectively activating the light source. The illuminator is located in the refractometer housing such that the light source is in a position on or about the prism assembly to illuminate a fluid substance to be measured. Light from the light source is introduced at a grazing incidence to a measuring surface of the prism. Phosphorescent material in the sample cover provides reticle illumination.

    摘要： A metal such as aluminum is produced by electrolysis of a compound of the metal in a solvent such as a molten salt. Electrolysis is carried out by passing a current from an anode to a cathode between which the solvent bath is situated. The cathode or cathode member is composed of a graphite substrate coated with a refractory hard metal such as titanium diboride. The coating adhesion of the TiB.sub.2 is improved through control of the manufacture and structure of the graphite substrate to favor a higher coefficient of thermal expansion and to have the density of the graphite fall within a range of 1.6 to 1.85 grams per cubic centimeter. The steps in producing the graphite may include working it so as to provide a grain direction. One embodiment includes aligning the refractory hard metal coated graphite in the electrolytic cell with the graphite grain direction parallel to the direction of current flow from anode to cathode. The refractory hard metal coating can be imparted by chemical vapor deposition and should exhibit a dense columnar structure which reduces penetration of the coating by molten aluminum.

    摘要翻译： 通过在诸如熔融盐的溶剂中电解金属化合物来制造铝等金属。 电解是通过将电流从阳极传递到溶剂浴所在的阴极之间进行的。 阴极或阴极构件由涂覆有难熔硬质金属如二硼化钛的石墨基材组成。 通过控制石墨基材的制造和结构来改善TiB 2的涂层粘附性，以有利于较高的热膨胀系数，并使石墨的密度落在1.6至1.85克/立方厘米的范围内。 制造石墨的步骤可以包括加工以提供晶粒方向。 一个实施例包括将电解槽中的难熔硬金属涂覆的石墨与平行于从阳极到阴极的电流方向的石墨晶粒方向对准。 耐火硬金属涂层可以通过化学气相沉积赋予，并且应该呈现致密的柱状结构，其减少熔融铝渗透涂层。
