I am looking at the original patents from Josef Rosenthal (1860-1934)
The Josef Rosenthal metalware factory in Vienna was a manufacturer of spirit and petrol cookers as well as high-intensity lamps :

The petrol cooker Phoebus was one of the products of Josef Rosenthal's company, which produced petrol cookers, paraffin lamps and soldering torches for many years and only stopped selling the last pieces and spare parts in the 1990s. Die motorang-Seiten über Benzinkocher
Is there a website where I can find more information about those patents (and more about Joseph/Josef Rosenthal as well)
Thanks so much to all (I am new to this forum, not sure I am posting at the right place)
Any help is welcome
