it l Scientific progresson more than 150 widely varied research projects is described in anannual- report issued by Dr. l-Ialdou A. Leedy, director of Ahnour Institute of Technology. The fiscal year 1949—l950 was the most'successful in'th‘e 14-year. histol‘y of. the Foundation, Dr. Lecdy stated in the 56~page report. Armour’s staff of almost 700' persons undertook-a total of 337 projects; he rcpdrtéd; This repre- sented an investment oi $4,614,958, an increase of 12.1 per cent over the previous year. ‘ “Foundation scientists and engi— neers specialize in the applied sciences, including physics. met~ allurgy. ceramics, mechanics, chemistry. and electrical engi- neering. They form research teams to solve many problems. A physicist, chemist, and metal- lurgist might pool their talents on one project, for example. Such varied subjects as palm oil, scouring cleanser, human muscles, music, and aircraft Windshields re— ceived the professional attention of researchers at Armour during the year. The Foundation’s work is sup- ported by industrial concerns and government agencies who sponsor individual projects. It is a not-for- profit,’ non—endowed scientific re- search organization, and any ex— ecss of income over expenses is used to finance fundamental re— search and defray cost of public service activities. Here are a few representative achievements: Physicists predicted, the acous— tics of a music pavilion before it was built, through ultrasonic stud- ies on a scale model of the struc— ture. Chemists developed a photo- graphic film that will operate at temperatures ranging from 65 de- grees below to 140 degrees above zero Fahrenheit. Engineers studied the design of aircraft Windshields which incorporate transparent, electric» ally conductive films for anti; icing. Ceramists invented a way to measure the cleaning efficiency of a scouring cleanser. Electrical engineers construct— cd instruments that record elec- trical, signals obtained from elec- trodes inserted into muscles. Metallurgists found a substitute for palm oil in hot dip tinning which is especially promising in regard to domestic supply, quality, and economics. Of direct aid to the nation’s de- fense effort were projects on rock- ets, cosmic rays, recoilless rifles, jet engines, low temperature lu- bricating oils, a flight simulator, and aviation fuel. “An increasing number of projects directly concerned with national security can be expect- ed,” Dr. Leedy predicted. “Ar- mour Research Foundation is prepared to carry out its share of this research mission.” The International Division of the Foundation surveyed technological conditions for the Republic of El Salvador and Cuba during the year. A new industrial research institute was established in Mexi» co City by the Bank of Mexico, and an Armour staff member acts as director of laboratories there. The Foundation introduced a radically improved form of mag- netic recording shortly before World War 11. Today a Magnetic Recorder Division serves 46 com~ panics licensed under Armour's patents. Physicists have taken more than 50,000 measurements of city noise in a methodical survey of urban clamor. The new informa- tion will be helpful to law- makers and city planners.

Other projects included the investigation of a steel building panel, a study of sound transmis- sion through windows, "and the development of light~weight ag- gregates for concrete. , The physics and electrical eng- ineering departments moved into a. newly remodelled Physics Research building recently. The metals department acquired two new laboratories, and other de- partments added to their re- search facilities. 01’ the 337 projects active dur- ing the year, 182 were sponsored by industrial concerns, 94 by gov— ernment‘ agencies, and 61 by the Foundation itself. cousin of paraffin. o and metallurgists. anodized Gold-Tone Won't Rust or Tammi iiiinois, Tech bookstore , @fimgfiw tfifi lists it‘ll}? canister this is The annual charity drive held [during the registration period this semester netted a total of $930 for day school students; “ ‘ ' This semester’s total may be compared with that of last sen master’s $1,094.

This concerted effort pro» duced a greatly expanded range of ”lashing First Steps The first step of Du Pont chemists and engineers was to produce poly— thene in the laboratory to confirm earlier findings. Then the product wastumecl over to chemical engi- neers for pilot-plant work. Finally, a plant for full-scale commercial pro— duction was designed by chemical, mechanical and electrical engineers Many of the most promising uses Blow-molded "Attrition" bottle, with molded closure. It emits a fine spray when squeezed. for "Aiathon” could not be realized until technical difficulties were over— come. For example, the chemical in» crtness, which is one of the outstand- ing properties of the material infilm form, also made the casting of flint from solution impractical becaueeit could not be dissolved in suitable solvents. In devising a special extru~~ sion technique to solve this problem, Du, Pont engineers opened up a whole new field of possibilities. Muillwnll bone for chemicals and foods are made of limit paper coated with “Aim/um." illicictnlleiynga hugger In film form, "Alathon” lends its strength, chemical inertness and re- sistance to grease and moisture to packages for chemicals, foods, metal parts and moisture-sensitive pow» tiers. In still another form in which these properties are employed, paper coated with “Alathon” is used as mapping for bakery products and moistureproof containers for chem- icals that would attack uncoated paper. (Experimentally, “Alathon” coated paper has been exposed to com centrated sulfuric acid for days with out harm; the same paper, uncoated, was ruined within a few minutes.) The protection of “Alathon” was extended to metal tanks and drums when Du Pont engineers developed a spray~flaming coating technique. In the field of electricity, too, “Nathan” is proving of great value. its outstanding electrical properties “liomo of you may Had it difficult, at first, to odimt yourselves to this early morning; class period." nice-{cube trays, refrigerator iii/’6; .., «a z‘ racy o .

In addition to bottles, these include tumblers, dishes, jar caps and. ice~ cube trays. Extruded as a film, it: germs for garment covers, tablecloths and rainwear. The future looks bright for “"Ala- than.” New applications such as ex- truded pipe for mines and separators for storage batteries seem about to be realized. Other uses yet undreamed of will no doubt emerge from the close, continuous teamwork of tech- nical men that typifies Du Pout research. “nun. u. o.
