This string of bar codes is actually patent priority data.
Generally, the priority data is marked with INID code "(30) Priority Data in Accordance with the Paris Convention" in patent documents, including four items: (3 1) Priority application number, (32) Priority application date, (33) Code of the country or organization applying for priority, and (34) Code of the country in the priority application submitted according to regional or international agreements, and at least one regional or international application has been submitted.
Your string contains two priorities. The country code is NO, which should be Norway. In other words, this patent has the priority of two Norwegian applications. The first application date was 1994.3.28, and the application number was 94 1 144 (none). The second application date is 1994.7.27, and the application number is 942790 (none).
I hope the answer will help you.
