As mentioned in the Kodachrome thread, I've attached a PDF of the original Richard Bent / Rowland Mowrey patent which I sourced as a PDF off espacenet. You can get to this service via your local european patent office (I went via British Patent office )
This version is in English, Espacenet will also allow you to download versions in different languages.

Thanks, that's easier then the version I was looking at, you can tell how old it is, it was filed on paper, and scanned at some point, by someone who was not that good at scanning, some of the pages are crooked.
