Special information is written in bold and/or with a grey background.
This is an example of special information!
All illustrations (Fig.) are numbered consecutively for each chapter. This means that a
reference to "Fig. 2-1" is equivalent to the 1. Illustration in Chapter 2.
Illustrations are often reduced to show the essentials, and can therefore differ from the
original. The only reason that covers or protective devices are not shown in illustrations
is to promote better understanding.
To address a broad range of variants, it is possible that example or principle figures
can strongly differ from the original or not apply at all.
Illustrations are sometimes confined to the depiction of a single version (e.g. only RH
or only LH...), especially when the information content can be appropriately applied to
other versions.
