Abstract
791,614. Arc-rupturing in switches. I-T-E CIRCUIT BREAKER CO. Feb. 3, 1955 [June 24, 1954], No. 3232/55. Class 38 (5). In arc - extinguishing assemblies as disclosed in Specification 791,613, wherein the ceramic plates have flanges or ribs extending along the full length of the plates so that the plates are of I- or U-shape in cross-section, the flanges of each plate are connected integrally with, or bonded rigidly to, an adjacent plate to provide a ducted unitary body. In Fig. 3, adjacent plates 30, 31 are bonded by applying to their flanges 32, 33 a cement comprising a slurry of the ceramic of which the plates are formed, along with a mineralizer, and pressing the plates together to produce a homogeneous whole. Alternatively, the plates may be bonded together by a glaze that matures at the same temperature as the basic ceramic. The assembly may alternatively be formed by casting or extrusion.
