Musical and iiive incoming Toriermdnce Large CroWd Attends Goodman Concert Morethan mappreciative friends ’ of Armour Tech heard the inspiring program rendered by the musical clubs at their second annual Goodman Theater Concert last Thursday night}; This large audience received more do— light in the way of musical entertain— ment in the three hours’ duration of the concert than hadlvbeen es' atbd or expected beforehand by a All critics and reviewers 59 agreed that this performance sur‘» passes by far that of last year, and that allv credit for the splendid mus- ical performance goes to the Musical Clubs’ most able director and guide, Mr. 0. Gordon Erickson. New Soloistu Heard Both the Orchestra and Glee Club have improved greatly since last year, having added a great many favorite selections to their rcpertoires. The incoming talent is also increasing rapidly. Among the new soloists who performed at the concert are the fol- lowing: W. Mashinter brought from his violin the glorious tones of "Meditation" from Thais; M. Nys— trom, tenor, sang “Trees” with or- chestral accompaniment, followed by an encore, “One Alone"; P. Woods, oboe, played the introduction to “Katinka” by Friml; A. Allegretti, violinist, surprised the audience by rising to sing the mournful interlude of the “Song of the Bayou." . Lighting Effects Prominent Soloists of last year who have re— turned to give their well-liked selec~ tions are B. Heine, accordionist, and F. Hrachovsky, Czechoslovakian ten- or, who sang several native folk songs. Negro spirituals by the Glee Club included the snappy “Ezekiel Sow dc Wheel" and the softer, more gentle “Goin’ Home.” During the latter (Continued on page four) Math Models Brow Praise Prof. Spengl'A-Plans To Display Models at Columbia As a result of the recent showing of his models at the Palmer House as a part of the mathematics exhibit of the National Council of Mathe— matics Teachers, Professor W. A. Spencer was invited to display them at a mathematics exhibition which is to be held at Columbia. University soon. Professor Spencer’s models have been the subject of much favorable comment in the past, the latest of which has arisen from his exhibition of some sixty charts and fifteen solid analytic geometry models. Praised by Mathematicians The charts showed a large number of geometrical constructions as well as the graphical representation of many curves and equations. The solid analytic models, familiar to most Ar- mour students, consisted mostly of hyperboloids, ellipsoids, paraboloids, many surfaces of revolution, and various self-explanatory string and sphere constructions.

Freshmen To Choose Orchestra This Week Ba] Tnbarin of the Sherman Hotel will he the scene of the first social attempt of the class of ’40. This ballroom is considered a fitting set- ting for any dance, and social chairv man Eugene Worcester announces that the music of an orchestra a]- will be featured. Under consideration are several orchestras that have played for past Armour dances, Corey Lynn, Lou Diamond, Emil Flindt, and Merrie Sherman. A definite decision‘ will be made this week, and bids priced at $51.50 will soon be placed on sale. The freshmen are looking forward to the same cesoperntion in putting this dance over that they have given :for the upper class afl'airs.

Oriental Room of Knickerbocker Discuss Production l Savings at A.S.M.E.' At the last meeting of the Armour Branch of the A.S.M.E., Paul Reh, M.E. ‘37 and special student working under Prof. H. P. Dutton, head of the social science department, spoke on “Time and Motion Study”. Describes Motion Study Describing time and motion study as a means of increasing production without raising production cost, he pointed out that problems in that field can be approached in several ways. The first, and almost obsolete method, is to check the motions of the best operators with a stop watch, noting.r the positions of the hands, ctc., and, the time necessary to carry out a specific operation. Using this data, a system eliminating the unnecessary motions is worked out. A more mod~ urn way, which is being introduced, is to take motion pictures of the more efficient operators at their work; by studying the finished picture, frame by frame, the analyst is enabled to study split second movements. Two Methods Used Itch used a problem solved by both methods to illu‘ rate his point. The problem consisted 01' assembling a common wall plug and a length of wire. Motion pictures of the origin- al motions ol‘ assembling previous to study, and the drawingr of the jig which speedcd up the assembly were shown. At the next meeting V. J. Jandasek, ME. ’37 and A. M. Meyer, M.E. ’37, will speak on “Hydraulic Drives” and “Railroad Signals”, respectively. Inspection trips for the A. S. M. E. Conference to be held April 19-20, will include the Crane Co. April 19, and the Western Electric Co., Mon- day, April 20. Dr. Oldenburg’ar to Show Curve Analyzer Dr. Rufus Oldenburgcr will con~ duct a demonstration of the har— monic analyzer at the University of Chicago Thursday evening, March 4, at 7 o’clock for the benefit of his evening school class in mathematical analysis and interested students. The harmonic analyzer is an in- strument which finds an equation for a given drawn curve when the curve is traced by the instrument. Specifi~ cally the harmonic analyzer gives the coefficients of a Fourier series. If the given curve represents a sound wave, the terms in the Fourier series correspond to harmonics so that the sound wave can be broken up into components. When musical instru— ments reproduce these components simultaneously, the sound represent- ed by the given curve is reproduced. Armour students not in Dr, Olden- burger's class, who are interested to see the analyzer are invited to join the class for Thursday night. The class will meet in room 401, Social Science Research Building, Univer‘ sity of Chicago, where Dr. Olden- burger will demonstrate the lnstru» inept. Site of Sophomore lnformal next Friday night. Car—ops Meet, Discuss Position as or Class Questions pertaining to their stand- ing in school were discussed by sec- tion ”A" of the co-ops at their meet- ing in the Mission building on last Friday. The questions which gained the most prominence were those rela— tive to the standing 01' the third semester comps with respect to the other classes of the school, class jack- ets, fratcrn fies, and membership in the professional societies. As the present, third semester men in the co—operative course comprise the first group of their kind, their ' a position has as yet not been ascertained. This group of third se— mester co~ops is scheduled to gradu- ate with the class of ’40 yet they en- tered with the class of ’39. In an of- l‘ort to coordinate the two divisions of the co—op department, the officers of group “I3” were invited to the meet— ing. According to the co—ops, if it is impossible for them to make up their minds to which class they wish to be— long, they can at least organize among themselves. Seniors interviewed for Job Placement Realizing that the best engineer- ing graduates must be spoken for first, many large concerns are already interviewing members of the class of ‘37 in co-operation with Armour‘s personnel director. Mr. W. N. Set- terberg. Three General Electric Company representatives interviewed all of the electricals and mechanicals of the senior class on one day and selected five men to Whom they offered posi- tions. If these men accept they will be able to take advantage of a train- ing schedule which places the men in each department of the entire shops for a short time. Placement Files Inspected The Container Corporation repre— sentative inspected the placement files of the class and selected twelve men for interviews at a. later date. The Prestolite Company man inter— viewed fourtecn seniors, and the Westinghouse Elevator Company in- teivicwed all the electrical and mech- anical engineering senior students. Armour and Company requested ap— plications from several senior chem- irals while the Texas Company asked for seven applications. The Goodyear Company interview— ed twenty-five men, and two l‘epre» sentativ s of United States Steel sub- sidiaries interviewed about seventy students. Other Companies to interview Several other companies, among them the Commonwealth Edison Com- pany, have stated their intention of sending representatives soon, and about a half dozen more large com— panies have been invited to send rep- resentatives. Class of ’39 Invites All Professors As Guests When the firs strains of music sound the opening of the Sophomore Informal in the beautiful Oriental Room of the Knickerbocker Hotel next Friday night, one of the largest crowds to attend an Armour dance is expected to fall into step. Unique to this dance is the open invitation to the faculty members and administra— tion officers to attend the affair as guests of the class of ’39. Feature Hollywood Singer Adding to the cnamourmcnt of the melodies of Tweet Hogan’s music, on- tertainment will be provided by Dorothy Skelly, as featured singer. Miss Skelly recently arrived in Chi- cago from Hollywood. She was em- ployed by M—G-M and same: in several shorts. Although it isn’t definite, so— cial chairman B. G. Anderson, says that perhaps Tweet Hogan will sing some of his song novelties. the comfort and relaxation of the dancers. The balcony which circles the dance floor has been provided with chairs, and the cocktail bar at the end of the balcony will be open, providing refreshments. Unique Lighting Effect The Oriental Room is decorated in cream color and has a glass dance floor under which colored lights play. The effect of the floor lights when the top lights are dimmed is beauti— ful. Bids for the dance may be obtained from B. G. Anderson and the mem- bers of his committee: W. A. Stuhr, I. M. Footlik, E. C. Mitchell, R. R. Tullgren, R. I. Jaifee, W. E. Kruse, and H. S. Anthon. Faculty Attends Cornell flanquet Dean llcald in company with eight members of the Armour faculty paid respect to Dr. Frederick Gardner Cottrcll by attending a banquet held in his honor last Tuesday at the- I)rake hotel. The annual Washington Award was presented to Dr. Cottrell by J. R. Van Pact, president of the Western Society of Engineers, in ap— preciation of Dr. Cottrell’s work and “social vision in dedicating to the perpetuation of research the rewards of his achievements in science and engineering." Famed by War Research Dr. Cottrell will long be remem- bered as an American chemist, met— allurg‘ist, inventor, founder and head of Research Associates, Inc. During the war he was one. of the principal directors of the research which re- sulted in perfecting a process to re- cover helium from oil well gases at a cost of about ten cents per cubic foot. Previous to that time, helium had been a laboratory curiosity cost- in;r $1,700 a cubic foot. He is best known as the inventor of the Cottrell precipitator, which, by electrostatic attraction, cleans gases of fine particles of dust and dirt, saving millions of dollars on» nually for chemical and metalluign-al industries. He has also been one of the chief figures behind the com- mercial productions of fixed nitrogen from the air. Armour Well Represented Had Dr. (‘ottrell chosen to com~ moi-claize his patents, the precipi— lator alone would have made him lwealthy, lustcid he dedicated his work to the benefit of mankind by or- ganizing: Research Associates to ac— quire and administer the profits of his patents to further scientific re‘ Search. Armour was represented 51: the banquet by Dean Heald, a Dean C. A. Tibbals, and From» Finnegan. Oldenbui‘g‘er. Penn. Poul— tcr, Snow. ngtborg, and Zigler. Arrangements have been made for
