Abstract

784,742. Brazing. EITEL-McCULLOUGH, Inc. Aug. 9, 1954, No. 23084/54. Drawings to Specification. Class 83 (4). [Also in Group XL (a)] A ceramic cylinder preferably of alumina or zircon is sealed to a metal disc by metallizing the ends of the cylinder by the molybdenum powder sintering process and brazing the metallized ends to the flanges with silver solder. Specification 784,743, [Group XL (a)], and U.S.A. Specification 2,619,611 are referred to.
