Thanks for that, Bob - interesting stuff. I was about to get onto the patents office there!
I guess, like rediffusion TV and radio, it was 'of its time' and has been superseded by a flat-screen telly in even the cheapest hotel room.
I have stayed in several hotels recently that have PA speakers in the ceiling: never heard anything from them, though.
