Abstract

592,637. Leading-in wires. SYLVANIA ELECTRIC PRODUCTS, Inc. May 16, 1945, No. 12308. Convention date, March 4, 1944. [Class 39 (ii)] [Also in Group XXXVI] Lead-in conductors for sealing to vitreous parts of lamps, mercury rectifiers, radio-tubes and similar discharge devices comprise a core of 38 per cent to 44 per cent nickel, 3 per cent to 8 per cent chromium, and the balance substantially of iron, with a tenaciously-bonded coating of copper or other metal of high electrical conductivity. The core alloy may contain from 0.1 per cent to 0.4 per cent of one of the metals in the group aluminium, zirconium, calcium, boron, beryllium, carbon, strontium, thorium. The conductor may be produced by covering a core of about 1 inch diameter with a copper sheath of cross-sectional area approximately 5 per cent to 25 per cent that of the core, a thin layer of brass or a 70- 30 silver-copper alloy being fitted between the core and sheath. Union is effected by brazing in dry hydrogen, the finished rod being then swaged and cold drawn or rolled to the desired wire diameter or ribbon thickness.
