Abstract

472,110. Sparking-plugs. GENERAL MOTORS CORPORATION. Dec. 13, 1935, No. 34601. Convention date, Jan. 25. Drawings to Specification. [Class 7 (iv)] [Also in Group V] A sparking-plug insulator has an alumina tip and a mullite or glass butt, in order that the tip may have high hot dielectric strength and good thermal conductivity while the butt, made of material of poor thermal conductivity, is kept at a lower temperature.
