Amendments introducing new features including the expressions
"much nearer" which are based exclusively on the original
drawings and which are isolated from other features derivable
from said drawings extend the subject-matter beyond the content
of the application as filed if, without said other features, the
defined subject-matter is ambiguous and thus its features do not
provide greater precision (c.f. T 0169/93, OJ EPO 1985, 193).
