Abstract

314,552. Soc. Franþaise des Bougies Pognon M. Pognon et Cie. June 29, 1928, [Convention date]. Sparking-plugs. - A sheath 7 of pulverulent material such as talc, quartz, graphite, or metal is placed between the insulator and central conductor. The central electrode is made in three aligned and interengaging portions. The middle portion 6 may be of soft metal and has its upper end 6a spread into close contact with the insulator 3a. Within the inner end of the casing a copper bush 17 has its upper edge spread against the casing while an enlargement 3b of the insulator is pressed against its surface. Specification 297,633 is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a) further powdered material 12 of an insulating character may fill the space between the insulator and casing. This subject-matter does not appear in the Specification as accepted.
