June 27, 1943
A new chemical development that enables American bombing planes to fly higher into the sub-stratosphere and stay there longer was disclosed today by the Westinghouse Research Laboratories.
The process, which increases by 50 times the high altitude life of carbon brushes for airplane generators, is the work of Research Chemist Howard M. Elsey. Heretofore, such brushes wore out in a few hours or a few minutes at altitudes above 25,000 feet, threatening to silence the radio and put the radio compass, landing gear, gun turrets and other auxiliaries out of order.
Here Dr. Elsey [inventor] adjusts a test device which showed the new process increased brush life to 100 hours or more at high altitudes.
