Uncle Sam test brass alloys. Washington D.C. To determine the correct amount of alloys necessary for desired results in the making of castings and other uses, the U.S. Bureau of Standards is conducting daily tests. 600 different portions of the alloy are used at the present time. The tests are made with brass bars which are melted in a high frequency induction furnace and the temperatures are recorded before and during the pouring into the molds. In the photograph, left to right: H.V. Gardner, Lemuel D. Jones, and C.N. Saeger, Chief of the Experimental Foundry at the Bureau

Studying why fruits taste that way. E.K. Nelson of the Department of Agriculture is shown making tests with an apparatus which the Department imported from Germany for the purpose of studying the essential oils or "flavor-giving" content of fruits and vegetables. At present chemists are acquainted with the essential oils of only a few fruits, such as some of the citrus group. The apparatus is a vacuum distill which permits the distillation of liquids at temperatures much lower than usual by reducing the pressure, 1/10/31

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. 6937

Hams now aged in 6 to 10 weeks. College Park, Md. Oct. 27. No longer is it necessary to age ham a year or so to obtain that sharp, pungent, cheesy flavor in the lean meat, so characteristic of southern style ham. Speeding up nature, the Maryland Experiment Station, University of Maryland, in cooperation with the U.S. Department of Agriculture, has developed a process by which it is possible to produce some of these characterisitc flavors in hams in relatively short time--6 to 10 weeks--by holding them at temperatures from 107 F to 125 F in specially constructed incubator. 1. The first step in the process is the thorough curing of the hams, three days being allowed for each pound of ham being cured. Mr. F.D. Carroll, of the Maryland Experiment Station, is shown with a few of the hams after they have been cured

Fuel conservation. Home insulation conserves fuel. Every homeowner can get behind his government's efforts to conserve fuel whether he heats his home with oil or coal, and both are strategically important. Fuel savings can be effected by keeping temperatures at reasonable levels, closing off unused rooms, and insulating in various ways. Windows can be weather stripped. Conservation of fuel will help release railroad and other transportation facilities for the movement of fighting materials

CAPE CANAVERAL, Fla. - A colony of brown pelicans takes advantage of a respite from winter temperatures to sun themselves along the edges of the Turn Basin in Launch Complex 39 at NASA's Kennedy Space Center in Florida. The brown pelican is found along the coast in California and from North Carolina to Texas, Mexico, the West Indies and many Caribbean Islands, as well as Guyana and Venezuela in South America. It is listed as endangered only in Louisiana, Mississippi, and in the Caribbean. The species is considered to be long-lived. One pelican captured in Edgewater, Fla., in November 1964, was found to have been banded in September 1933, over 31 years previously. Individuals can weigh up to eight pounds, with larger pelicans having wing spreads of over seven feet. Their nests are usually built in mangrove trees, but ground nesting may also occur. Nesting takes place mostly in early spring or summer with the male carrying nesting materials to the female. Although the female builds the nest, both share in incubation and rearing duties. The Merritt Island National Wildlife Refuge coexists with Kennedy Space Center and provides a habitat for 330 species of birds including brown pelicans. Photo credit: NASA/Jack Pfaller KSC-2010-1348

The bright cirrus-like clouds of Neptune change rapidly, often forming and dissipation over periods of several to tens of hours. In this sequence spanning two rotations of Neptune (about 36 hours) Voyager 2 observed cloud evolution in the region around the Great Dark Spot (GDS) at an effective resolution of about 100 km (62 miles) per pixel. The surprisingly rapid changes which occur over the 18 hours separating each panel shows that in this region Neptune's weather is perhaps as dynamic and variable as that of the Earth. However, the scale is immense by our standards--the Earth and the GDS are of similar size -- and in Neptune's frigid atmosphere, where temperatures are as low as 55 degree Kelvin (-360F), the cirrus clouds are composed of frozen methane rather than Earth's crystalse of water ice.

P-34718 Range: 210,000 kilometers (128,000 miles) This natural color image of the limb of Triton shows the largest surface features at about 3 miles across. The picture is a composite of images taken through the violet, green and clear filters and shows a geologic boundary between a rough, pitted surface to the right and a smoother surface to the left. The change between surface types is gradual. The image also shows a color boundary between pinkish material in the upper part of the image and whiter material in the lower part. The geologic and color boundaries are not the same. That implies that whatever supplies the color is a very thin coating over a different underlying material in which the geologic boundary occurs. The colored coating may be a seasonal frost composed of compounds volatile enough to be sublimated at the very low temperatures (40 K to 50 K or -387.4 F to -369.4 F) prevailing near Triton's surface. Possible compositions of the frost layer include methane (which turns red when irradiated), carbon monoxide or nitrogen. The color in this image is somewhat exaggerated: Triton is primarily a white object with a pinkish cast in some areas. ARC-1989-AC89-7052
