Ouchterlony in Russian sounds like Okhterlon (Okhterlone), there is even page in wiki about one of them on Russian (http://ru.wikipedia.org/wiki/%D0%9E%D1%85%D1%82%D0%B5%D1%80%D0%BB%D0%BE%D0%BD%D0%B5,_%D0%90%D0%BB%D0%B5%D0%BA%D1%81%D0%B0%D0%BD%D0%B4%D1%80_%D0%90%D0%BB%D0%B5%D0%BA%D1%81%D0%B0%D0%BD%D0%B4%D1%80%D0%BE%D0%B2%D0%B8%D1%87)
