I found a way to make the article name appear in the site's header <title></title>
You must be using SE friendly urls, so that the article name appears in the link instead of action=viewarticle&articleID=71
in articles.php
find
$_page['header'] = _t( "_ARTICLES_H", $site['title'] );
and replace with
$_page['header'] = _t( "_ARTICLES_H", $site['title'], $_REQUEST['articleUri'] );
in inc/languages.inc.php
find
$str = str_replace('{0}', $arg0, $str);
$str = str_replace('{1}', $arg1, $str);
$str = str_replace('{2}', $arg2, $str);
after those lines add,
$str = str_replace('-', ' ', $str);
now in your site admin panel
under Settings > Language Settings
search for _ARTICLES_H, the current string is probably
{0}: Articles
click Edit and change the string to
{0}: Articles > {1}
after the language has recompiled, the article name will now appear in the title
