...mountain stream. It has two mouths. Instead of scales it has what seem to be plates of silver. When the currents (which at times go 50 m. p. h.) are too fast for the ganoid, it creates a vacuum in its lower jowls, hangs on a rock by the suction and brakes itself with the plates of its silver armor...
...Slack's Westinghouse task was to make more permeable windows. A film of glass would serve, were it stout enough to withstand the suction of the Lenard vacuum tubes. Dr. Slack rounds the end of his vacuum tube until it resembles the butt of a test tube. Then he blows the glass to gossamer thinness. A last step is to exhaust the tube. This creates a knob at the tube's end, a knob so frail that when shattered its glassy film floats in air. so stout that it is as strong as steel. Result is that a pressure...
Pierce Arrow has redesigned its bodies, introduced "free wheeling" in all its models, improved the 132-h. p. motor in its Salon and "Group A" lines by a new nine-bearing crankshaft, improved carburetion by adding a combination "suction silencer and cold-air intake with seasonal adjustment," discarded rod brake-controls for cable controls.

...Birkenhead, England; the Liberty Tubes, 5,800 ft. long, mountain tunnels, sole route from the South to Pittsburgh. Ancient sub-river vehicular tunnels without protection from motorgas exist at Glasgow and under the Elbe at Hamburg. Two old tunnels under the Thames at London have been equipped with suction-&-exhaust fans. First tunnel to require a new type of ventilation was the 8,463-ft. commuter-used Holland.† For years Engineer Ole Singstad, assisted by the U. S. Bureau of Mines and Illinois and Yale universities, studied to perfect a suitable system. Now air is pumped into a channel...
...seep. Before entering the pool it will be impregnated with chlorine gas, which lends a greenish color. The results are tested twice daily by comparing a test-tube full of water with a graded color chart. In addition the floor of the tank will be periodically subjected to the suction of a large curry comb, connected by a hose to the vacuum end of the pumps...
