I have an old Silex (before Proctor) coffee pot that works on a similar principal. While I prefer to use my Capresso Team maker, the old Silex does make a very fine pot of coffee.
You put the grounds in the upper bowl, along with a funky glass filter. The upper bowl has a tube that reaches to the bottom of the lower bowl. When the heat is put to it, the water is forced up through the tube into the grounds, when all of the water is in the top you remove the heat (mine is not automatic), and the water is then sucked forcefully back into the lower bowl, the funky glass filter keeps (most) of the grounds in the top.
I usually only bring it out for "show" on special occasions. Older people recognize it, people my age (41) usually have never encountered a coffee maker like it and are fascinated.
It is a pain to keep clean though, hence the preference for the modern maker, that and the automatic timer! Nothing like fresh ground fresh made coffee waiting when you wake up
This isn't mine (I stole the image from eBay), but is very similar.
