Interferometer tests standard gages for automobile manufacturers. Washington, D.C. May 28. I.J. Fullmer of the Bureau of Standards is shown with an interferometer by means of which differences in length are measured in terms of wave-lengths of light to the millionth of an inch. A four-inch square precision gage is being compared for length with the Bureau's standard 4 inch, which is rectangular in shape. These gages are tested against the master gages which the different auto manufacturers check their measuring devices so that the parts of the cars separately made can be, when assembled, fitted perfectly. The standard gage and the master gage are shwon being compared in the interferometer, 52837

And fall. Washington, D.C., April 9. Weather Bureau observers stationed along the principal rivers of the United States soon will be able to follow the rise and fall of nearby river merely by picking up a telephone and dialing a given number. Preliminary trials for the last few months here show that a new automatic sound river gauge effectively and economically supplies the facts weathermen need in forecasting floods and supplying other information on river conditions for many interests. More weather bureau stations will install the new gages as fast as possible. (1)A river gauge on the Potomac River in the Capitol, where formerly a U.S. Weather Bureau Scientist had to go to this gauge box to take a reading on the river's height, all he has to do now is to pick up his telephone, dial the number of Potomac River, listen for a gong, then a buzz and at last another buzz, and then he will know whether the river is rising or falling, 4/9/38

CAPE CANAVERAL, Fla. - Inside the Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, the Orion crew module is positioned on a special portable test chamber and prepared for a multi-point random vibration test. Accelerometers and strain gages have been attached to Orion in various locations. During a series of tests, each lasting only 30 seconds, Orion will be subjected to gradually increasing levels of vibrations that represent levels the vehicle would experience during launch, orbit and descent. The data is reviewed in order to assess the health of the crew module. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch later this year atop a Delta IV rocket and in 2017 on NASA’s Space Launch System rocket.
