When I first saw it, I immediately assumed the worst - that our German friends are inhaling teutonic sewer gas to get off.
A quick trip to babelfish's translation page was little help. But it did turn up such linguistic nuggets as this:
In the offer inventions are like the Klo Atmer, the wiedergeburt, or the fish head roof impact device.
Finally, a translated paragraph shed light on the mystery: in the event that you cant escape from a smoke filled building, you stick a tube into the toilet and inhale the rancid (but smoke free) sewer gas. Or as babelfish put it:
The fresh air equipment of the Kaliforniers William of cross-beam is to save with fire in smoked dwellings the life to humans. According to cross-beam must they in addition only a hose into a toilet insert and the "fresh air" deeply existing in the tubing system inhale.
Great idea, now that I understand it. Sewer air is better than no air at all. I will add a rubber tube to my stale cache of duct tape and plastic sheeting.
