“…Morgan (21), who had been investigating photoelectric cells for the control of roentgenographic exposures, was the first to discover the usefulness of the multiplier phototube in the detection of x-rays. Independently and somewhat later, Smith (26) and Moriarty (22) made the same discovery in successfully completing a war assignment not fundamentally different from many problems in chemical control.…”

“…Fuse Testing. This assignment was the devising of an infallible, nondestructive, rapid method of inspecting hand-grenade fuses (22,26). If a fuse contains too little powder, the hand grenade explodes prematurely.…”

“…The appearance in the literature of the ultraviolet absorption spectra of many compounds is obviously very valuable. As an example, one recent paper (22) presents the spectra of about a dozen anthracene derivatives. The catalog of ultraviolet spectra issued by American Petroleum Institute Research Project 44 at the Xational Bureau of Standards ( 14) is particularly useful for hydrocarbon analysis, although the spectra of some nonhydrocarbons are also included.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
