Sign of the Times: baseball cap gas mask
On July 19, 2004, the New York Times highlighted U.S. Patent No. 6,752,146 to Boris Altshuler and James F. Reynolds, directed to a baseball cap/gas mask to protect the average American citizen against a biological or chemical attack.
The Altshuler-Reynolds mask is an embodiment of what is known as a "supplied-air respirator." The user breathes purified air that has been propelled by a small fan through a filter into the mask.
The air is to be purified by activated carbon, material which CR Clean Air typically uses on an industrial scale to scrub the air of coal-burning power stations.
The trick here is that activated carbon does not remain active indefinitely, and separately does not interact with all molecules.
The assignee, CR Clean Air Technologies of Westfield, New Jersey, is not planning to manufacture the mask, however, because it is not related to the company's core business of producing technology that reduces industrial air-pollution emissions.
