Thanks for sharing.
I made a personal guide with patents in chronological order.
Where there was an absence of patents with the dates, I inserted the newspaper ads or magazines with the dates, pages and names of the older newspaper or magazine, where, for example, there was an announcement of the market launch of the equipment.
Too bad the file got too big (110 pages) and I had to split it into 5 parts. grrrrr
So I posted the images on my blog so I could always have the basic information available where I was.
Here the Part II with with patents in chronological order.

Good stuff. It's a shame they are all images, so Google Translate won't work.
