    Abstract: Improved seal structure, particularly useful in the fabrication of electric lamps and the like includes a crystalline alumina member and a thin molybdenum member sealed to one another by a substantial mass of interposed sealing glass having a softening point of approximately 1,400* C. to 1,600* C., and forming a concave surface between the sealed members which intersects the respective members at a small angle having a radius of curvature which is large as compared with the thickness dimension of the molybdenum member.

    Abstract translation: 特别可用于电灯等的制造中的改进的密封结构包括结晶的氧化铝构件和薄的钼构件,该组合物通过大体积的约为1400℃至1600℃的软化点的密封玻璃而彼此密封。 并且以与钼构件的厚度尺寸相比大的曲率半径的小角度在与各构件相交的密封构件之间形成凹面。
