Abstract

Magnesium alloys contain, respectively, 3 per cent aluminium and 1 per cent zinc, and 10 per cent aluminium. The Specification as open to inspection under Sect. 91 describes also a magnesium alloy containing 1.5 per cent manganese. This subject-matter does not appear in the Specification as accepted.
