Page 8 University Daily Kansan Thursdav, April 16. 1953 150 Persons Injured In Buenos Aires Riot Buenos Aires—(U.P.)—Angry mobs surged through Buenos Aires today in a wave of death, burning, and rioting touched off by two bomb explosions at a giant political rally. Officials said at least six persons were killed. Unofficial reports said 150 persons were injured in stampedes when the blasts rocked the big plaza Del Mayo where President Juan D. Peron was addressing 100,000 supporters late yesterday. Fires set in retaliation by pro-Peron rioters last night and early today burned three headquarters buildings of opposition political parties and the swank Buenos Aires Full House Attends Showing of Film Students were turned away at both showings of Steinbeck's "Grapes of Wrath" yesterday in Fraser theater and 426 Lindley. Audiences were responsive at this first of a series of movies planned for an American Civilization Film series to be shown this spring. Prof. Edward F. Grier, chairman of the committee on American civilization, said no arrangements had been made to show the films in a larger auditorium because of the film's location but that the meter film used in these documentaries would appear only as a blur if used in Hoch auditorium. This film series serves as an introduction to a two year major to be offered by the college next year. The purpose of the course, according to Prof. Grier is "to give students a fuller understanding of American life than could be offered in a single department." The next section of the film series will be shown Wednesday evening in 426 Lindley. It will be three shorts: "The River," "The City," and "Architecture West." 3 Give Recitals in Topeka Miss Marian Jersild, instructor in piano, and Miss Elizabeth Townsley, instructor in voice, will present a recital today for the Topeka Music Study club at the Central Congregational church in Topeka. John Pozdro, instructor in theory, also will present three piano numbers.

Pannunjom, Korea—(U.P.)-Red trucks and ambulances today delivered the first of 605 Allied sick and wounded war prisoners to Kaesong—last stop before freedom—and the United Nations command indicated it now may be willing to resume full-scale truce negotiations. Allied POW's in Kaesong The UN notified the Reds it wants a meeting of liaison officers today to deliver a letter from Lt. Gen. William K. Harrison, head of the United Nations truce delegation. The Reds have been grumbling at delays in delivery of the UN answer. The United Nations command said Gen. Harrison's letter will be presented to the Reds at 8:30 a.m. (5:30 p.m., Thursday CST). The letter, addressed to North Korean Gen. Nam I, presumably is the UN reply to repeated Communist demands for a special conference to arrange resumption of the long-stalemated armistice talks. Gen. Mark Clark, supreme UN commander, and other allied officials have indicated they would be willing to consider resumption of the truce negotiations only after twenty-four dust-covered trucks bearing the Allied sick and wounded met Monday's prisoner exchange jolted into the Red truce camp at Kaesong last night. the Reds had made good on their promise to return sick and wounded Allied war prisoners.

A GROWING FIELD— Instrumentation Modern manufacturing trends at Du Pont bring ever-increasing opportunities for technical men Do you think of instrumentation as applying only to work in electricity and electronics? Or would you also include problems in chemical processing, materials of construction and materials handling, as well as application of equipment — both mechanical and hydraulic—for measurement and control systems? At Du Pont, instrumentation is applied to widely diverse areas of manufacturing operations. It calls for many different technical backgrounds. In a typical instrument group there may be men whose formal training has been in mechanical, chemical, electrical or metallurgical engineering, or in physics, etc. Instrumentation is becoming more and more important in the chemical industry. In fact, many of today's processes and products would not be possible without modern measurement and control systems. The trend toward continuous processes means challenging and constantly increasing opportunities for instrumentation men. Du Pont's instrument program includes research, development, design and supervising installation of process control equipment. Some of the work is done in the central Engineering Department at Wilmington. However, most of the major plants across the country now have their own organized instrument groups. Frad R. Struder, B. Metal W., Rensselaer P.I. 50, examines a pressure strain recorder with Allen R. Burke, E.E., Princeton '39, Richard G. Jackson, B.S. in Ch.E., Columbia '42, and Gregory L. Laserson, Ph.D. in M.E., Columbia '49, test an infrared gas analyzer. Paul D. Kohl (left), B.S. in M.E., Purdue 'A6, checks the assembly of an experimental control instrument. So you may visualize the scope and diversity of the work, here are examples of instrumentation recently developed and designed by Du Pont technical men: 1. A device to measure flow of approximately 30,000 lbs, per hour of gas at more than 10,000 p.s.i. To give $1.2\%$ accuracy and be responsive to flow-changes of five cycles per second. 2. A device to monitor continuously 1200 similar temperatures. Equipment to record temperature and sound alarm at a deviation of $1^{\circ}\mathrm{C}$. from desired point. 3. An automatic control system to maintain a predetermined pressure-temperature relation in a large-batch autoclave during spontaneous reaction between two chemicals. Thus it can be seen that Du Pont instrumentation is limited to no single avenue of engineering. Men with an aptitude for the work get experience in many phases of the Company's technical activities—and an excellent background for positions in management and administration.
