These industrial life-lines were explained by Rob- ert Zane, former Armour student, who is now an engineer for the Okanite cable company. After spending his freshman year at Armour, Zane went to Illinois, from which University he gradu- ated in 1933. After reminiscing briefly on his Armour days, Mr. Zane briefly described his company’s products. Extra high voltages, the under. graduate electron engineers were told, must be conveyed in paper- wrappecl cables. A myriad of other lnsulations for lesser pressures was also enumerated and de- scribed. On the 66,000 volt transt‘nission cables employed by the Edison company, mechanical pressures of up to 115 pounds per square inch were produced between cables by the heavy currents passing through the cables, according to Mr. Zane. Other engineering prob lems were also discussed. After the speech, a sound film produced by the Okanite company and narrated by the famous to well Thomas was shown in room UZW, Student Union meeting; room.

Ar AME Meeting Of the fifty-six papers being presented at the three hundred and seventy-eighth meeting of the American Mathematical Society, ten are products of either present or former members of the faculty of lllinois Institute of Technology. The meeting will he held at the University of Chicago on April 1] and 12. Four of the papers are being de- veloped by two present members of the faculty: Professor L. R. Wil- cox in the field of algebra and Dr. John De Cicco in the field of get» metry and topology. The topic of Dr. Wilcox’s talk will be “Exten- sions of Semibodular Lattices”. This subject is the result of re. cent study by the speaker, and it represents very modern mathe matical concepts. Three papers will be presented by Dr. De Cicco. Their titles are: “The Ditlerential Geometr v of the baguette Group B6,” Infinite Groups Generated by Equilong in- volutions and Symmetries,” and “Lineal Element. ’l‘ranslorrnations which Preserve Dual-isothermal Families.” Dr. De Clcco studied under Professor Kasncr at Colum- bia University, obtaining his (loo toralc in 1938. The other men who were for mer members oi" the faculty and are also presenting papers are: Dr. G. E. Hay, Dr. A. 'l‘. Lonseth, Dr. l. M. Niven, Dr. W. T. Scott, and Dr. Sam Perils.

Dr. B. B. Freud will par ticipate in the council which is the governing body of the organ ization. Five other men shall pre» sent, to the meeting papers on re search. These men are Dr. V. l. Komarewsky, Dr. Bruce Longtin. Dr. Hugh J. McDonald, Dr. 8. Win stein, and Dr. M. J. Murray. “Effect of silver ion coordination upon the Rama spectra ol‘ some unsaturated compound” is the title of the paper to be presented by Dr. Murray. The project is the work being done towards a mas ter’s degree by Mr. H. .l. Taufen and is being directed by Dr. M. .l. Murray. Dr. F“. F. Cleveland of the physics department has assist- ed in the preparation of the paper. The problem concerns the state of the unsaturated hydrocarbons dissolved in silver nitrate and Water. Upon investigation of the spectra a considerable difference has been found between the solu- tion of pure unsaturated hydro- carbons and the solution of the same, dissolved in silver nitrate and water. This fact supports the idea ol‘ Dr. S. Winstein and Dr. Lucas (of California Institute of Technology) the idea being that the silver ion attaches itself at the double bond by coordination. Dr. Winsteln will present a paper entitled “The effect of neighboring groups and the na— ture of the reaction medium on the steric results of some replace- ment reactions.” Dr. Winstein be- gan work upon the project at Harvard University and now at Armour has been assisted by Mr. R. E. Buckles who is working to- ward a doctor’s degree and Mr. H. V. Hess who is working for a master‘s degree. The paper per- tains to the steric aspects or organ— wmmmm if.“ replacmnent reactions. Ordhieri if" in El replacement reaction the product is a more image of what one might expect. in other words, a carbon atom turns inside out in the course of being substituted. The work being reported demon» stratus that certain groups near by the carbon atom being substi tilted. may intervene during the replacement process to give un~ looked for intermediates. The not sterile result of replacement re- action with such neighboring growls present in the molecule, turns out to be the retention of configuration. in illustration, the carbon atom concerned has been turned inside out or inverted twice during: the replacement process. Practical result of the finding is that it becomes possible by con- ”filling the reaction condition to obtain either reversion or reten- tions~ as a steric result, thus where the product of one steric result is the useful one and the other one is not. it becomes possible to ob- tain the desired product. “The liquid vapor composition of the ethyl alcohol — glycerol benzine system." is the paper be‘ ing presented by Dr. McDonald. Dr. McDonald has been assisted in research by Mr. Ralph Petri who graduated in chemical eng- ineering in 1940. “Catalytic dehydration and (le- hydrogenation of butyl and amyi alcohol” is the subject matter of Dr. Komarewsky’s paper. As a re— sult of such findings Dr. Komr arewsky has been able to produce butadiene which is used in make— ing synthetic rubber. Also he has been able to produce isoprene which is the basic matter of na- tural rubber.
