Substitute materials. Timber connectors. Use of wood in the construction of Army chapels is shown here, one of 570 similar structures erected since last fall. All of them were built with wood trusses like these or with glued laminated wood arches, saving many tons of structural steel for more strategic purposes. New methods for timber joints have made it possible to reduce the amount of material needed for trusses and other load-bearing members

The new 'flying tube' airship. Washington, D.C., Mar. 14. Immediate commercial development of a new lighter-than-air airship of novel design, which its engineering sponsors believe will revolutionize air transportation, bringing safety, speed, load capacity, and easy maneuverability to airship performance, was announced today. Air sucked through the tube will create a vacuum in front and give a propulsive kick at the outlet. Universal joints will be located at the entrance and exit of the tube, moving in any direction of the air intake and outlet, thus steering the flying tube. The ship will be entirely metal clad and the lifting power will be helium gas in aluminum partitions. Garret W. Peck, designer and vice pres. in charge of construction, left; and Clifford C. Jones, specialist with the Inter-Ocean Dirigible Corp., right, with the working model of the ship

Shipbuilding (Norfolk Navy Yard). This welder is torch flaming a part for a new destroyer on the ways at the Norfolk Navy Yard. Riveted joints have been cut down by as much as two-thirds in the last few years, as welding has been developed to a point where it provides equal strength. Welding means less weight and a saving in steel

Experts at Bureau of Standards study effect of corrosive soils on specimens of pipe. Washington, D.C., Aug. 8. Of interest to home builders the country over is the study being made by experts at the National Bureau of Standards of the effect of corrosive soils on pipes and protective materials. Samples of pipe which have been buried for four years in fifteen soils differing widely in their characteristics, are being tested. Included are several varieties of ferrous materials as well as copper, brass, and bronze. Soldered and brazed joints, protective materials, and pipe made of a composition of cement and asbestos are also represented. Walter Johnson, of the Bureau, is pictured removing graphitic corrosion from cast iron with an air-driven tool. The corrosion products are too hard to be removed with a brush or by chemical treatment, 8/8/38
