    And Gavrisheff's patent is here! ;
    http://www.google.co.uk/patents?id=PG9qAAAAEBAJ&pg=PA7&dq=Blish+prism&hl=en&sa=X&ei=BOhzT6CrIbCQiAfs5LjkDw&ved=0CEEQ6AEwBA#v=onepage&q=Blish%20prism&f=false

    There is just enough informationto allow an artisan to construct the device, which is what patent specifications required
