I tried to copy/paste it into Google Translate, but I was only able highlight and copy about 2/3 of the text... so pasting it into a translator just ends up giving sentence fragments.

Doing a search for "color picture tube" on the site comes up with an article comparing tests of their tubes versus the RCA version. Its interesting to see that they were trying to move ahead and innovate at such as early stage.
