...trouble with this system is that the plate and the photoemissive surface have to be kept close together in a vacuum (electrons do not pass through glass), and gases from the plate quickly spoil the sensitive, metallic surface...
Pipe Dream. VacCo Pump Co., Inc. of Indianapolis brought out a new type of pump for unclogging household drains. Working on the principle of the old-fashioned plunger, the Pull-It Pump can build up a vacuum of 15 inches with the help of a vacuum valve inside the rubber force cup. Price...
...named because France's famed Architect Le Corbusier once said: "The house is a machine for living") tries to be functional, but only succeeds in destroying privacy. "The 'living area' becomes an echoing cavern reverberating with every sound from children's yelling to the vacuum cleaner's whine.

In 1913 he worked out the regenerative circuit, which outmoded crystal receiving sets with a sensitive vacuum tube system; his superheterodyne circuit, developed in 1918 while serving in France, is still the basic circuit of AM radio. In 1939, he perfected a method for eliminating static (now known as FM). A professor of electrical engineering at Columbia University for the last 20 years, the earnest, driving inventor...
