Boxes placed in Smithsonian in 1881 by telephone inventor opened for first time. Washington, D.C., Oct. Three boxes which Alexander Graham Bell, inventor of the telephone, and two associates placed in the secret archives of the Smithsonian Institution in 1881 and which have remained [un][?]opened since, were formally opened today in the presence of Bell's two daughters and a group of scientists. The boxes contained among other things the original working model of the first machine ever to record on wax and reproduce the Human voice. In the photograph, left to right: Mrs. David Fairchild, daughter of the inventor; Mrs. Gilbert Grosvenor, another daughter; Alexander Graham Bell, great-grandson of Bell; T.H.

Production of butylene glycol. Butylene glycol is recovered from corn fermentation liquors in an experimental still in the pilot plant of the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is one step in the Department's research that led to the development of a fermentation method for converting corn into butylene glycol, a chemical that can be used in making anti-freeze for automobiles and in the production of commercial solvents for various manufacturing purposes. Research now is directed toward the development of a practical way to turn the butylene glycol into butadiene, from which synthetic rubber can be made. The work has already been done on a laboratory scale

Production of butylene glycol. Dr. Lynferd J. Wickerham selects the bacteria that will convert corn into butylene glycol at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is one step in the research that led to the development of a fermentation process for converting corn into butylene glycol, which has proved successful on a semi-commercial scale. Butylene glycol, hitherto a relatively rare chemical, can be used in making anti-freeze for automobiles and in the production of commercial solvents for various purposes. In the laboratory, the scientists have succeeded in turning butylene glycol into butadiene, from which synthetic rubber can be made. The next step is to find a way to carry out this process on a larger scale

Science and research. Studies of non-coking coals. V.F. Parry, supervising engineer of the Golden, Colorado field station of the U.S. Bureau of Mines is "sighting a coke bubble." This procedure is used to determine if a given coke has changed its properties or it is similar to another coke. One gram of powdered coal is heated at 820 degrees centigrade for two and a half minutes. The resulting "bubble" is then compared with a standard chart to determine its characteristics, as revealed by the shape it has assumed. This research is part of a project to find ways of improving the quality of coke from western coal

Science and research. Mineral prospecting. Speed in metallurgical analysis, to match the rapidity with which the nation arms itself, is possible through use of the spectrograph, a marvelous new machine used for study of materials through measurements of the arc of light they emit when heated. The aluminum and magnesium industries, steel companies and foundries use it for quick study of metals. Mines use it for exploration. The spectrograph will yield an analysis of seven elements in fifteen minutes determination, which would require up to four hours by old chemical methods. Three students in defense training courses at a famous mining-engineering school listen as an instructor shows them how the machine operates. Golden, Colorado

Science and research. Mineral prospecting. Electrical prospecting for metallic minerals may be carried on by using the dual coil radiometer to measure the electro-magnetic field of the earth, as it may be influenced by the presence of an ore body. Students training for war jobs in the minerals industry, or for service with the armed forces, are shown hunting for ore. A student at the left operates the field generator. The coils about the middles of the two others are made up of many strands of copper wire which act as transformers. The student second from right watches the level on his stationary coil to measure the electro-magnetic field. After completion of training, many students will be given commissions in naval ordnance, where they will use electronics for airplane detection. Colorado School of Mines, Golden, Colorado

Science and research. Mineral prospecting. Chemical prospecting for oil becomes more and more important as the war goes on the demand for oil increases. Petroleum engineers call chemical prospecting the first scientific approach to the detection of oil in the earth. The big glass condensers, with which these engineering students are working with a professor of geophysics are used in a soil analysis test. The percentage of wax left as residue at the end of the experiment indicates the nearness of petroleum to the site from which the soil sample was taken. Colorado School of Mines, Golden, Colorado

Albany, California. At the Department of Agriculture regional research laboratory a worker is taking a sample of chopped blanched cabbage. Before dehydration, vegetables are processed various ways, a quick steam bath is one of these ways. By laboratory tests it is determined which processing method retains the greatest percentage of vitamin content and produces the most attractive product

Production of butylene glycol. Dr. George E. Ward turns a valve in one of the experimental fermentation vats in which corn is being converted into butylene glycol at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This is part of the laboratory work that led to the development of a fermentation process for converting corn and other grains into butylene glycol on a semi-commercial scale. Butylene glycol can be used in making anti-freeze for automobiles and in the production of commercial solvents for various manufacturing purposes. Department scientists have succeeded on a laboratory scale in turning butylene glycol into butadiene, from which synthetic rubber can be made. Now they are trying to do it on a semi-commercial scale

Science and research. Mineral prospecting. Micro-fossils can play an important role in locating the proper spot to drill an oil well. A magnificent history of the flow of ancient seas, of climate, of the rise and fall of empires of primitive forms of life is preserved in stone. Students in defense training courses at a famous mining-engineering school learn to decipher and piece together for an engineering conclusion the facts contained in micro-fossils found in crushed rock. Here they are at work in the micropalenontological laboratory with binocular microscope using special lamps for horizontal illumination. A professor of the geophysics department stands at the far end of the table. Colorado School of Mines, Golden, Colorado

Science and research. Studies of non-coking coals. William S. Landers, assistant chemical engineer at the Golden, Colorado field station of the U.S. Bureau of Mines, uses precision gas analysis apparatus which measures the properties of gas made in a coke oven. This is important, since gas is a usable by-product of coke. These studies are designed to make western coal more adaptable for coke uses

Production of butylene glycol. Dr. George E. Ward inspects two types of pure butylene glycol made from corn at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. Dr. Ward and his associates developed a fermentation process for converting corn and other grains into butylene glycol that has given good results on a semi-commercial scale. This chemical can be used in making anti-freeze for automobiles and in the production of solvents for various manufacturing processes. Department scientists have succeeded on a laboratory scale in turning butylene glycol into butadiene, which can be used in making synthetic rubber. Now they are trying to do it on a semi-commercial scale

Production of butylene glycol. A department scientist checks the results of experimental fermentations of corn to produce butylene glycol at the Northern Regional Research Laboratory of the U.S. Department of Agriculture at Peoria, Illinois. This research led to the development of a semi-commercial scale of a fermentation process for converting corn into butylene glycol, a chemical that can be used in making anti-freeze for automobiles and in the production of commercial solvents for various purposes. Studies are now underway to devise a practical method for turning butylene glycol into butadiene, from which synthetic rubber can be made. The work has already been done on a laboratory scale
