Defense housing, Erie, Pennsylvania. Pre-fabricated sheets of asbestos reinforced with gypsum serve as an economical base for plaster walls and ceilings. These sheets, nailed directly to studs, also afford protection against heat and cold. A crew of fourteen men (ten lathers and four laborers) can lathe a four-unit building in a few hours. A crew of plasters moves in as the crew of lathers moves out. Although defense homes are speedily built, they are soundly constructed. Government inspectors keep a rigid check to see that all construction materials live up to government standards

Nyssa, Oregon. (vicinity). Japanese-American family was evacuated from a coastal area to a reception center. Subsequently they volunteered for farm work and moved to the FSA (Farm Security Administration) mobile camp. From there they were hired as a group by a local white farmer. They will be allowed to remain on this farm for the duration of the war. When such an arrangement is made the U.S. Employment Service must inspect and approve housing facilities and wage standards

New machine to test brake linings designed by Bureau of Standards. Washington, D.C., March 16. A new machine, both in design and operations, has been installed at the National Bureau of Standards for the testing of brake linings. The machine permits the study of brake linings under conditions closely approaching those of actual sevice and yet which can be accurately controlled. It will make less difficult the complex job of revising the Federal Government's specification for auto brake linings. Wil. Holt of the Bureau is shown in the photograph, 3/16/38

Flame propogation in gas engines photographed. Washington, D.C., Aug. 26. A study of the mechanism of the flame propogation in the cylinder of a internal combustion engine is being made at the U.S. Bureau of Standards for the National Advisory Committee for Aeronautics. A secial bomb made of steel, shown in the foreground, and designed to withstand pressures up to 500 lbs. to the square inch is used to show the progress of the flame and the rise in pressure which may be recorded photographically during the gas explosions under carefully controlled conditions. The camera, where the recordings are made, is in front of Dr. Ernest F. Flock of the Bureau of Standards, carries its film on a drum which may be revolved up to 4,000 revolutions per minute, this camera also records a neon light flashing at a thousandth of a second. The independent effects of pressure, temperature and charge composition upon flame speed and explosion ratio may be made with this equipment, 82637

Fruit farmer clearing out irrigation ditch. Placer County, California. Irrigated farming is a new thing to this man who migrated from Oklahoma and has now bought a farm through the Federal Land Bank. Fruit farmers in this section are fast losing their farms due to long indebtedness to Federal Land Bank and many farms are being bought by Okies and Japanese who, because of lower living standards and willingness to grow gardens, cows and pigs instead of specializing exclusively in fruit, have a chance to make a go of the farms.

Government discovers method to preserve film.

This may cause some distortion of the image, and therefore is of particular importance where the image must be true to scale, such as in aerial photography. C.O. Pope is shown with a type of expansiveity tester used and which was designed by the Bureau of Standards.

Bureau of Standards designs mechanical batter to determine liveliness of baseballs. Washington, D.C., Feb. 21. Using a newly designed apparatus, the U.S. Bureau of Standards today began experiments to determine the relative home-run qualities of American, National and International baseballs. In conducting the tests a scientist pulls the trigger of an air gun loaded with a wooden projectile representing the slugger's bat. The projectile strikes a baseball causing it to fly toward a ballistic pendulum. After each of such hits the scientist takes a reading on the pendulum. It tells him how hard the ball hit the pendulum, or whether it was a homerun, a double, [...]st a pop fly. Dr. H.L.

By means of this new apparatus just designed by the metallurgical divisions of the National Bureau of Standards, it is now possible to make 700 micrographs per working day of the structural effect of corrosion on cross sections of metallic specimans. This new machine uses roll film of 900 negatives at one loading, thus dispensing with the repeated loading and unloading of individual film holders by which method the Bureau was only formerly able to make 12 micrographs per working day.

Measuring relative humidity by radio. Washington, D.C. June 9. The hair element for measuring relative humidity in radio weather sounding balloons has proved innacurate because of very slow response at the cold temperatures encountered in the upper atmosphere. F.W. Dunmore, Radio Engineer of National Bureau of Standards, has just developed a new device for the U.S.Navy which will overcome this effect and at the same time will not be affected in response by temperature. He is shown in the photograph observing a graph on the recorder being produced by radio signals from an ascending balloon carrying the new device. This is the first record obtained with this new developement and shows a repidity of response much greater than the hair hygrometers Hitherto used. 6/9/37
