This photograph shows how the two halves of a trailer house, delivered individually, are assembled by simply rolling them together on previously prepared foundations which consist of a few posts driven into the ground connected by planks upon which the house halves roll by means of small wooden wheels. Each half is light enough to be towed behind a 3/4 ton truck or passenger car. They come fully equipped with all essential furniture and equipment, either built-in or stored inside during transport. They are connected to each other by a few bolts, while the roof sections meet in ridges over which a common cap is laid. The whole operation may take between one and three hours, including connection to previously prepared utilities. The section or halves measure 26' x 7'9," thus permitting highway transportation without special permits. Any number of sections can be combined. Two- and three-bedroom houses. Recreation buildings, bath houses, and even very large barracks, have been constructed by TVA (Tennessee Valley Authority) on the same general plans but using more sections

Production. Aircraft engines. A skilled mechanic and determined war worker, Zed W. Robinson, proves that skin pigment bears no relation to efficiency of work. He's one of many Negroes employed in a large Midwest aircraft plant in skilled and semi-skilled capacity. Tightening bolts of a cylinder barrel during the final build-up of an airplane engine is one of the jobs which, until fairly recently, was closed to members of his race. But this war demands that no American because of race, creed or color shall be barred from work. Melrose Park, Buick plant

Dr. Miklos Hatenyi, Hungarian-born research engineer at the Westinghouse electric and manufacturing company. He made various types of nuts and bolts, attached weights to the bottom of each model and heated them to "freeze" the stress lines, then cut slices from the center of each model and photographed the thin plastic sections to show which nut or bolt divided the "pull" among threads

Pittsburgh, Pennsylvania. By using a polarized light apparatus to take pictures of plastic models of turbine nuts and bolts, Dr. Hetenyi, Hungarian-born research engineer at the Westinghouse Electric and Manufacturing Company, has discovered how to make this fastening device up to forty per cent stronger. He found that nuts and bolts with broad shoulders and tapered bodies distribute stress on threads more evenly than do ordinary nuts and bolts
