German Patent Office website

LOTS of cool stuff here!

Here is a link to the German Patent Office's web-server. There is an English page, and several search engines. Lots of cool stuff from Stirling to generators to anything you can think of. Not just German patents, either, but patents from many countries, US CA FR JP, etc.
Below is a link to a Canadian patent for an Improved Permanent Magnet Generator. Don't know if the link will work as is but the website has lots of stuff.

Here is the link for the main website. If you do a Dogpile or Google search for German Patent Office, you will be able to find it.

Lots of the patents are in .pdf format. At first I thought that only the first page of the patent was available, but finally I noticed the page forward buttons on the Adobe Acrobat reader, and I was able to look at each page.

If you go to their search engine and paste in this document ID number you can find the patent that I mentioned specifically:

CA0002368426A1-24862821926

Interesting patent for a Hallback array dynamo. I think someone mentioned that as an idea in here before.

Go to main website and use the search engine to find this document ID:

Whoa! Here's another neat one. Supposedly this design is good for small generators running at variable speeds, with lots of features that have been kicked around here:
