SMITH Tilting and Non-tilting Mixers, Pavers, Weigh-Mix. PARSONS Trench Excavators, Backfillers. C. H. & E. Portable Saw Rigs. Pumps, Hoists, Material Elevators. KWIK-MIX Mixers Concrete, Plaster and Mortar. At Los Angeles, the coliseum in Exposition Park is being enlarged to a seating capacity of 105,000. When completed in 1931 for the Olympic Games, this giant stadium will be one of the largest in the world. Three N. E. C. products were selected in providing efficient plants for handling excavation and concrete requirements. A Koehring Heavy Duty Shovel speeded progress on the earth work. Two Smith 14-S Tilting Mixers were installed for mixing concrete, one on each side of the stadium. National Equipment Corporation, the greater name in construction equipment, aids man in carrying out his engineering achievements. "Concrete Its Manufacture and Use," a complete treatise and handbook on present methods of preparing and handling portland cement concrete, will be gladly sent on request to engineering students, faculty members and others interested.

4 THE OHIO STATE ENGINEER 1 CINCINNATI Welcome to Our Plant I T IS our pleasure to greet you all... some for the first time, others we have met before... back again to take up the careful preparation for a constructive and definite career in some phase of Engineering. You will find here an organization and plant; an organization able to study the market for Cincinnati Milling Machines, anticipate the requirements of users, design and build machines of an advanced design and do all these things economically; a plant equipped to produce machines of an accuracy and quality which modern manufacturing plants all over the world demand and have the right to expect. We want you to come to our plant and see personally the men, the methods and machines that make for a modern and progressive organization, devoted for over 46 years to the solving of industry's milling problems.

5 2 THE OHIO STATE ENGINEER DYNAMITE clears the way for modern engineering wonders! The HUDSON RIVER BRIDGE How DYNAMITE was used to blast tunnels for anchoring gigantic cables IN after five years of stupendous labor.... the Hudson River Bridge, connecting the states of New York and New Jersey, will be completed. It is a single-span bridge feet long. At either end, a gigantic tower, 650 feet high, rises to the sky. The Hudson River Bridge as it appears under construction. The construction of this mighty bridge is proof enough that, to the modern engineer, nothing is impossible! In this undertaking, as in countless others, dynamite played a huge part. Du Pont dynamite was used for blasting approaches to the Hudson River Bridge... and for blasting the anchorage tunnels for the cables. About 3,000,000 pounds of dynamite were required! The engineer of today... and tomorrow... needs to know all there is to know about dynamite... the tool that helps to build skyscrapers, dams, subways, tunnels, roads and railroads. How can you know more... now... while you're still in college? Write the du Pont Company for a copy of the "Blasters' Handbook." This booklet contains a wealth of information about explosives... information gathered in 128 years' experience in making and improving explosives. It is compact... handy. It is used in the classrooms of leading technical institutions. Your free copy is waiting for you. R ES. U.S. PAT.OFF. EXPLOSIVES E. I. DU PONT DE NEMOURS & CO., Inc. EXPLOSIVES DEPT.

7 4 THE OHIO STATE ENGINEER U+4- I N GUARD! S. F. HENDERSON Armour Institute of Technology, 1926 Contract Administration Out in mid-rink, flying skates cut the glassy surface of the ice into powder amid the clatter of sticks and the hoarse, inarticulate cries of human beings in combat.back and forth goes the puck, now dexterously propelled down the side-lines by a fleet forward, now shuttled rapidly to and fro amid a tangled mass of sticks and legs. )[et fast as it moves, it never eludes the watchful eyes of the two heavily-armored huskies who tend the goals. On guard, ready to thwart disaster with stick, skates, or any part of his body, the good "goalie's" work is ever vital, and often spectacular. In a large organization like Westinghouse, there is need for a number of such expert "goal tenders." Occupying positions in the Accounting, Legal and Contract Departments, they carry on quietly their important work of guarding the resources, patent situations, and contractual relationships of the company. And among them may be found many younger college men, like those whose pictures appear on this page, who have found in this work an opportunity to secure recognition and worthwhile reward. G. C. SALTZMAN Carnegie Institute of Technology, 1923 Patent Department E. H. HORNBARGBR Virginia Polytechnic Institute, 1921 Contract Administration Among the important pieces of electrical work bandied by Westinghouse in recent years may be mentioned the following: Cascade Tunnel Electrification, Great Northern Railway; Network Protector Installation, Chrysler Bldg., New York; Hydro-Electric Generating Equipment, Coolidge Dam, Arizona.
