Executives and machines were to work side by side, their noises deadened by sound-absorbing ceilings; machines were to be bright orange against black floors to prevent accidents by making everything conspicuous; walls and ceilings, part blue to reflect ultraviolet rays, part green to energize workmen, part white for light and cleanliness.

...Dellinger now believes that high-frequency daytime reception improves with sunspot activity, possibly because increased ultraviolet radiation from the sun at such times makes more ions in the ionosphere. The magnetic shifts resulting from the ultraviolet bombardment, however, may cause delayed interferences with low-frequency reception and night reception in general...
Odors of roast beef, warm rubber and ozone pervaded the 22nd floor of the Kansas City (Mo.) Hotel Kansas Citian last week.

Cause: ultraviolet light which reaches the food through the transparent wrapper. Cure: tinting cellulose wrapping paper with a faint yellow dye which obstructs ultraviolet light...
