From the time of their earliest use in hospital operating rooms, the handling of most inhalation agents has been fraught with danger of fire or explosion from static sparks. With the introduction of cyclopropane and other newer type gases, further attention was focused on the elimination of this hazard. How could the potentials of the anesthetists, the patient and the apparatus be equalized to eliminate the possibility of spark? The answer was found in fastening the group together by means of silver chains and other conductive materials. Connected into the circuit, a device consisting of high resistances prevents the formation of static charges of any important degree of intensity.
Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
