Moreton, professor of direct and alternating current machinery, a motor-generator set has recently been received by the electrical de- partment. The set, which has been in— stalled in the dynamo laboratory. consists of a 110 volt direct current interpole motor and two three phase alternating current genera- tors. The speed of the motor may be varied from 750 to 180 revolu— tions per minute. One of the gen- erators is a four pole outfit; the frequency of its output may be varied from 25 to 60 cycles. The other generator is a 12 pole ma- chine of the stationary armature type; it generates currents whose frequencies may vary from '15 to 180 cycles. The terminal voltage of these machines may be varied by making use of a field rheostat. Study Made Easier An interesting fact concerning these machines is that they pro- duce an electromotive force which, closely approximates a sine wave, Due to construction features a thorough verification of the funda- mental laws of alternating current work is made possible. A study of this kind was not possible before, because no source of available a1— ternating current approximated a sine wave upon which the funda- mental laws are based. In addition, it.uiil...be..p9§sib1e to prom study the fun _ harmonic currents, electromotive forces having frequencies varying from 25 to 60 cycles per second and combinations of the fundamental and third harmonics. Variable Phase The wave form of the resultant electromotive force produced by a fundamental and third harmonic may be changed by changing the phase relation; in this machine this is accomplished by rotating the stationary armature through a small are. A means of measuring or determining the variation of iron losses in alternating current apparatus with the .wave-lorm, a condition which should be studied throughly, is thus provided. Professor Moreton states that a number of new experiments involv- ing the use of the new equipment are being prepared to be given in the second semester of the Junior Laboratory Course. Professor Research at Petroleum Meeting The Anti«Knock Session of the American Petroleum Institute was held at the Stevens Hotel on No- vember 12. Professor Daniel Roesch, or the department of Automotive Engineering at Armour, presented a demonstration of an Acousti- meter. This instrument, for meas— uring engine knock intensities, pro- duced microammeter indications which were projected on an en- larged screen. Demonstrations were made showing variations of knock intensities with mixture ratio, variable throttle ratio, vari- able spark advance, and with fuels of various knock intensities. Professor Roesch also made a re— port on the measurement of ex— haust noises of about forty out— board equipped motor boats at Lake Geneva some eighteen months ago. In this work a range in noise intensity of from one to five huh- dred ergs per square centimeter per second was found in unmufitled racing quad engines. At a recent meeting of the Ar- mour Branch of the A.S.M.E., Prov lessor Roesch gave a demonstra- tion of his apparatus to the students. Armour Institute of Technology.

With this assurance they will then definitely plan the dance, it not, the men who have paid, having received receipt for their money will get their money back upon presenting the receipt. CYCLE SEEKS RECORDS All seniors are urged to fill out and hand their biographies in to the Cycle staff on or before Wednesday, November 26. Detailed information from each graduate is desired concerning place of birth, department, high school, honorary groups, social fra- ternities, clubs, organizations, ath— letics, publications and other ac- tivities that have to do with campus life. This information is vital for the early completion of the senior section. Blanks may be obtained from Stanley Livingston in the book store and after com— pletion can be given to any mem— ber of the staff or placed in the Cycle box located on the first floor of the main building on the ele— vator shaft. veniber 26. The jackets, which are now on display, are to cost $7.50, according to Bob Wilson, chairman of the auxiliary committee. Pay- ment will be required at the time of measurement, to prevent any jackets being left on the hands of the committee. The jackets will be furnished by Rexiord and Keller, according to the samples furnished the class. Delivery will be in two weeks after the measurement. Assembly Learns oi World Wide Dutiools At an assembly held Thursday, November 20, a discussion of the state and progress of countries of the world was given by Dr. John H.

M. Smith, assistant chief engineer of the Illinois Division of Waterways. Mr. Smith’s address was given with the aid of colored slides of various waterway projects. A large part of the time was devoted to a description and explanation of the waterway along the upper Illinois river. Mr, Smith's talk started with the early forms of canal and river transportation and went through the various steps of development to the modern methods of today. lie pointed out that, although to the novice it would appear that there is less river traffic now than in former times, in reality there is probably more because of the in» creased carrying capacity of barges over motor driven boats. Mr. Smith described the con- struction and maintenance of the large modern canal locks, using as examples those recently installed near Chicago. Mr. Smith is well known in en- gineering circles and was a member of the advisory board on the design and construction of the Panama Canal.

Tau biota Pi to Set Up Marker Plans are being made by Tau Beta Pi, honorary engineering fra- ternity, for the erection of a mark- er upon the Armour campus to commemorate the twenty—fifth an“ niversary of the chapter. This marker will be placed upon the plot of ground directly north of the Faculty Club entrance, and will be, according to the tentative plans, a rock-finished concrete base with a large bronze Bent upon the top. The work is being done by the present pledge group under the di— rcction of the active members. The Bent has been cast and the base will be erected in the near future. Professor Huntly is acting as a supervisor, and is arranging for the materials. It is hoped by the chapter that this marker will be an inspiration and a constant rem minder to the lower classman that Tau Beta Pi is a goal for all men to work toward. Plans for the dedication of the marker are not yet fully decided upon. Eta Kappa Nays Hold? Eonuention Eta Kappa Nu, national hon— orary electrical engineering fra- ternity, held their 26th annual convention at Ames, Iowa, on Fri- day and Saturday, November 14 and 15. Nu Chapter of Iowa State College was host. Delegates from other schools who passed through Chicago were guests of the Chicago Alumni Chapter at a dinner given at the Hotel La Salle, Thursday evening. Afterward, a meeting was held at the Lighting Institute in the Civic Opera building. A. R. Draus, of Delta Chapter, was the official Armour representative at this meeting. The Armour delegation to the convention at Ames, consisting of W. Drigot, W. E. Penfold, C. Blah— na, and R. Patzelt, made the trip by automobile and arrived with two worn tires and front wheels out of alignment. The business session consisted of registration of delegates, discussion of topics, and the election of offi- cers. G. H. Kelley, formerly a stu— dent at Armour Institute, was elected president of the organiza- tion. The social program included a dinner, a smoker, and ended in the witnessing of the football game between Iowa State College and the Kansas Aggies on Saturday. 0n the trip home our represent- atives were accompanied by the Oklahoma A. and M. delegation and the horneward journey made more interesting by an exchange of experiences and happenings. Dr. G. L. Scherger delivered an address on the subject of “Vienna: Her Culture and Art" at the Bel— don—Stratford Hotel last Thursday. The body assembled there was the Junior Friends of Art of which Miss L. Olga Menu is the head. This or— ganization has a membership com~ prised of many society women of Chicago. Tuesday, November 25, 1930 NWE'W SQEENTES’E lit Williibld‘l‘lld’l‘fi MEQHANWAL MAN Engineer Shows Results of Research at Assembly FEATURES ELECTRON Front seats will be at a premium for the assembly to be held tomor- row morning, for Dr. Phillips Thomas, research engineer of the Westinghouse Electric dz Manufac- turing company, is bringing his electric flea circus to the Institute. He has presented his circus before various groups with such huge suc~ cast that it was necessary to turn people away because of limited facilities for seating. It is feared that a large number of outsiders will be on hand to attend this ex- hibit so the students are warned to get to the assembly on time. There will be no music at this as- sembly. The time for the assembly has been tentatively set at 10:30, but the definite time will be an~ nounced on the bulletin board. Uses Electrons Doctor Thomas uses the electron in much the same way as a show- man uses his trained fleas. He thinks of the electron as a flea on the back of an atom. In numerous spectacular and interesting ways he forces these electrons to do things similar to those that they are made to do when working for an engineer. In addition to the electrons, Doctor Thomas will bring Rastus Robot, his mechanical slave, with him. This robot will perform various duties at the sound of his master's voice with a quiet, aston~ lshing efficiency.....1n addition to seeing this mechanical man work. the students will have the privilege of listening to his voice. for, miabile dict“, he speaks. While watching these marvels of this modern age of machinery, the undergraduate body will have the privilege of hearing Doctor Thomas explain how these things were conceived and developed by him in conjunc- tion with his associates. Campus Club Smoker to Be Held Tonight A smoker and card party is to be given by the Armour Tech Campus Club in its rooms in Chapin Hall this evening. An attendance of about thirty-five is expected, since only active members are to partici— pate. Professor Marigold, faculty advisor of the club, will also be present. There will be plenty of "cats and smokes." An elaborate program is not being‘planned but several skits will be presented by members. There will be enough bridge and pirlochle decks to supply all wants and a prize will be awarded to the best plggie player. A. S. MP. E. Smoker Es Enjoyed by Members The Armour branch of the American Society of Mechanical Engineers held its first smoker of the year at the Theta. Xi house last Friday evening. After a number of rounds of bridge silence was called and the pledges of Pi Tau Sigma put on several stunts. Included in these stunts was one “The Stu— dent’s Idea of an Ideal Class" and another “Broadcasting Station. A. I. T.,” both of which were very good entertainment. After the refreshments were served. all gathered around the piano to sing some “Reducer" songs composed especially for the A. S. M. E. and then continued to Thursday, November 20, Professor Anisbsry delivered his new lecture on “Literature, Its Inspiration and Power” to the students of Northern Teachers College Michigan. \ at Marquette, warble on popular themes Important guests of the evening the A.
