Ultraviolet lamp fights bacteria across many industries
A new mechanically produced ultraviolet lamp kills air borne bacteria and mold on surfaces while remaining safe for humans. It concentrates 80 percent of its radiation in the bactericidal range and is used in coolers, displays, bakeries, and hospitals to prevent spoilage and cross infection, with a notable role in meat aging and tenderness.
Milestones of Science and Engineering Innovations
The article notes 10,000-watt mobile steam electric power plants on railway cars being built for the U S Navy Bureau of Yards and Docks to supply emergency power on coasts. It also reports a six-foot-per-day gain in the Estes Park Continental Divide tunnel with a ventilating system powered by 2,200-volt motors. It highlights electron microscope discoveries in entomology revealing mosquito windpipes as tree-trunk sized, and a Rochester company patents a coaxial frequency modulation loudspeaker reproducing 50 to 15,000 cycles.
