...directly to the invention of the gas-filled incandecent lamp which saves U. S. users of electricity, according to estimates. $1.000,000 a night. The same concept led to his creating almost complete vacuums in thermionic tubes. To do this he was obliged to design a new powerful mercury pump. Result is cheap, highly efficient vacuum tubes for radio, and long distance telephony. Another result was Dr. Coolidge's perfection of dependable x-ray tubes and his design of tandem x-ray', tubes whose radiation is almost as powerful as radium's gamma rays. (Manhattan...

Aeronautical engineers have long experimented with the two-cycle engine for airplanes. In such an engine the four strokes of the pistons-1) intake, 2) compression, 3) explosion, 4) exhaust- are reduced to 1) compression 2) explosion. Fuel is forced into and out of the cylinders by a pump. Complex lubrication is dispensed with by mixing oil with the gasoline. That advantage largely accounted for the failure of most experiments to date: the burned oil left heavy carbon deposits. Last week a new, light two-cycle engine was described by Dick Roberts, plump aviation editor of the Toledo Blade...

How the snake got in its predicament neither Foreman Davis nor anyone else knew. Next day Foreman Davis looked to see if the snake was still there. It was. With threshing tail it had ripped the web to shreds, but several strands still held its head fast. The spider, warily keeping to the upper part of the web, was busily spinning fresh strands to strengthen...
