The practice: 1. only (central) governmental bodies, or 2. private bodies having officially received royal sanction. Although 1. has largely fell out of practice, this is why KTH has its name. 2 corresponds to the Royal Academies. Thus the frequent use of the arachaic-sounding misspelling "Konglig" in student circles, to circumvene this. But all this should not affect the translation of THS into English.
