Abstract

1300520 Joint-making packing GENERAL MOTORS CORP 28 Oct 1971 [12 Nov 1970] 50185/71 Heading F2B [Also in Division F1] A sparking plug ceramic-to-metal sealing gasket 9 comprises an annular sintered compact which has a density of 6À95 to 7À05 gm./c.c. and is formed from powdered iron of a purity of at least 99À4%. In the manufacture of the sparking plug, the ceramic insulator together with the gasket 9 and, if required, a further gasket 10 are first inserted into a steel shell 2. Axial pressure is applied to the shell to compress the gasket or gaskets, the material of the shell being softened at a thin section by passing an electrical current through the shell to cause resistance heating.
