This idea for a system that would "sanitize" theater patrons as they entered a theater
lobby was proposed & published in 1945. Who knows, with all the current Corona-Virus
concerns, perhaps this system isn't as far-fetched as it seems! The parts were described
as follows: 1) Air vents in foyer ceiling through which air and immunizing chemicals descend
on patrons; 2) Tanks containing the chemicals; 3) Pressure pump which operates system;
4) Vacuum pump that sucks dirty air off patrons. Also sucks up shoe dirt & water that
may be tracked in by patrons; 5) Dirt & moisture trap; 6) Floor vents; 7) Ultraviolet
lights in air ducts to further sanitize the air. (The the actual type of "sanitizing chemical"
that was going to be sprayed over arriving guests was never specified)
