Abstract: An alkali metal corrosion resistant vacuum tight metal-toceramic seal is formed between a high alumina ceramic body and a refractory alkali metal resistant metal member, such as Cb-1Zr, by interposing a powdered brazing mixture comprising by weight a majority of elemental columbium powder and a second metal powder selected from the class consisting of iron and nickel, and firing the assembly in vacuum at a temperature between 1,500*C and 1,675*C to partially melt a portion of the powder to form a melted bonding phase component interstitially of the undissolved columbium particles for bonding the ceramic to the metal part.

Abstract: A mounting ring and method is described for referencing the cathode to the reflector in a short arc lamp, and the cathode/reflector to the anode and the lamp exterior. A reference plane is formed on the mounting ring. One or more planes parallel to this reference plane are formed in a brazing fixture and spaced so that the tip of the cathode is at a controlled distance from the reference plane. The same reference plane or one parallel to it is used to control positioning of the anode and lamp exterior. Axial concentric surfaces are formed on the ring and on at least one cylinder in the brazing fixture to control concentricity of the ring, cathode and reflector, and of the ring, anode and lamp exterior. When two or more cylinders are used, surfaces on a first cylinder can be made to expand at the same rate as the ring, with one surface constrained at brazing temperature by a concentric surface on a second cylinder which expands at substantially the same rate as the electrode.
