...section of the Los Angeles sewer system which no live eye has seen since the city's discharge started flowing through it, 220,000,000 gal. per hr. at the rate of 3 ft. per sec., is the 6-mi. tunnel under the Del Rey Hills to the ocean. Last week Reuben Brown prepared to travel those six subterranean miles in a non-sinkable 9-ft. punt...
...Constitution provides that states may make compacts or agreements with one another provided Congress ratifies them. Best example is the compact setting up the Port of New York Authority which links New York and New Jersey together with four bridges and the Holland Tunnel. As a State Senator, Mr. Toll served in the negotiations for the Colorado River Compact which was to divide water power and water rights from Boulder Dam among seven Western states. He soon learned that states seldom agree, because they have no machinery for negotiation. The Colorado River Com pact was ten years in the making...
...McCrea was succeeded by Samuel Rea, who had been the active supervisor on the tunnel job. His administration extended through the completion of the Hell Gate project, the building of Manhattan's Pennsylvania Hotel, the War years, and the beginning of the 1920's. These were prosperous years for the Pennsylvania, which ran its gross income from...
Presenting motion pictures taken in the NACA's new "superspeed" wind tunnel at Langley Field, Va., where airflow up to 750 m.p.h.* is possible, Dr. Lewis proved that at 575 m.p.h. the smooth flow of air over the wing top suddenly breaks away in a feathery "shock wave" which completely nullifies lifting power. Cause is an area of excessively compressed air, built up by the airfoil's passage. Same phenomenon occurs at the tips of propellers. Only chance for speed greater than 575 m.p.h. is a mechanism for changing wing and propeller shape when the plane reaches...
...that engineers may also pass, a small cart has been placed in the tunnel. Thus, lying prone on the cart, with the trolleys a few inches above the nape of his neck and the subway just below him, the engineer grasps a cable and draws himself and cart through the tunnel...
