Contents of the online supply

The institute does not take over any guarantee for the topicality, the correctness, completeness or quality of the supplied information. Liability claims against the authors, referring to idealistic and financial damage, which was caused by the use or non-use of the offered information or by the use of incorrect and incomplete information, are basically impossible, unless the authors are proved having acted deliberate or gross negligent. All supplies are not-binding and noncommittal. The authors reserve themselves the right to change sections of the pages or the entire supply without separate announcement and to complete or to delete the publication from time to time or finally to stop it.

References and links

In case of direct or indirect references to other Internet pages (" links"), which are outside the responsibility of the authors, a liability would only enter into force, in which the institute has knowledge of the contents and can technically prevent the use in case of illegal contents.

The authors therefore explain expressly that at the point in time of the link setting the directly linked pages were free from illegal contents. The authors do not have any influence on the current and future organization and on contents linked of the pages. Therefore they dissociate themselves hereby expressly from all contents of all linked pages, which were changed after the link setting.

This statement applies to all linked pages within the own Internet supply as well as to foreign entries in from the authors created guest books, panels and mailing lists.

For illegal, incorrect or incomplete contents and for damage, which develops from the use or non-use of such offered information, only the provider of the linked page is responsible, and not that one which refers via links to the respective publication only possible and reasonable for them to prevent the use in the case of illegal contents.


The authors are endeavoured to consider in all publications copyrights of the used diagrams, tone documents, video sequences and texts and to use own created diagrams, tone documents, video sequences and texts or to use license-free diagrams, tone documents, video sequences and texts.

All protected labels and trade marks within the Internet supply specified (also by third party) are subject without reservation to the regulations of the copyrights and the possession rights of the respective entered owners.

However only the naming of such labels and trade marks does not mean that brand names are not protected by rights third! The copyright for published, of the authors themselves created, objects remains alone with the authors of the pages. A duplication or a use of such diagrams, tone documents, video sequences and texts in other electronic or printed publications is not permitted without agreement of the authors.


If within the Internet supply exists the possibility for the input of personal or business data (email addresses, name, addresses), submission of these data take place on expressly voluntary base. The use and payment of all offered services - so far technically possible and reasonable - is permitted also without specification of such data resp. under specification of anonymizated data or an alias.

Legal force of this non-liability

This non-liability is to be regarded as part of the Internet supply, referred by this page. If sections or individual formulations of this text and of the valid legal situation should not correspond, to no more or not completely, the remaining sections of the document remain unaffected in their contents and their validity.
