Mechanical pumps have a certain limit beyond which they cannot decrease the vacuum chamber pressure any further. So Dr. Hickman has designed a sort of chemical pump which goes to work after the mechanical pump has done its best. A spray of oil vapor is shot in one side of the chamber, out the other. Some of the gas molecules roaming inside are struck by the oil particles, adhere to them, are thus escorted outside through the oil vapor exit...
...Bordeaux mixture is so named because the French vine-growers of the Bordeaux region used to spray their plants with copper sulphate and lime-not as a plant medicine but as a deterrent to thieves. An alert viticulturist named Millardet discovered that vines so sprayed were not attacked by downy mildew.

One afternoon last week, with 35,000 miles in her wake and her bows scoured with the spray of more than seven seas.

...ultrashort waves pass through the atmosphere beyond the horizon, they encounter a constantly varying complex of atmospheric conditions. They are bent, reflected, shifted with every change in the constantly shifting atmosphere, like spray from a hose in the hands of a drunken gardener. Such waves hit a receiving antenna beyond the horizon only sporadically and by accident. The Zworykin invention, using two receiving antennae hooked up to a single receiving station, and an automatic device to match the wave length at the transmitter and receiver to the atmospheric conditions of the moment, is designed to assure unbroken, even, ultra-high...
