Vol. VII. No. 5 Armour Institute of Technolpgy, Chicago, Illinois Tuesday, March 10, 1931 ANNUAL lNNSl’lNillN SMNNNN SN'l' MN NEXT llllhdl EVE Schommer a n cl Ains- hary Featured on Program Al“ W. S. E. HALL Plans for the freshman smoker which have for several weeks been going through a period of devel— opment are soon to attain realiza— tion. This event is to take place next Friday night at 8:00 at the W. S. E. hall, located on the twelfth floor of the Engineering Building at 205 West Wacker Drive. Since this is their first social event of the year, the fresh are striving hard to make it a big suc— cess. In order to achieve this and make the evening a highly success- ful and enjoyable one various forms of entertainment have been provide e.d Professors Schornrner and Ams- bury, well known members of the faculty, have assured social chair— man L. A. Callen of their presence as speakers on Friday night. Orchestra to Play A fifteen piece orchestra recently formed among freshman students, is to play on the occasion, offering popular song hits of the day. Its members are: T. Cherwin, J. Cramer, B. Peterson, C. Cunning- ham, J. Tamney, N. Krause, N. Colburn, C. Wilson, 0. Johnson, D. Travcr, R. Ekroth, J. Rodigher, T. Reavy, B. Hemmick, and W. Gund- arson. Tickets 0n Sale Chairman Callen urges every freshman who possibly can to at- tend this event Tickets aré now on sale for a quarter, which will be amply repaid in the way of real enjoyment. Refreshments will also be served. a Will Make Attempt To Split Atom Soon Artificial lightning of 15,000,000 volts will be unleashed in the cen- ter of Berlin in March. The artificial bolt will be used in an attempt to split the atom. It is believed to be one of the most dangerous experiments ever under~ taken by man. The voltage has been heretofore unequaled. One grain of water or any other matter contains energy which the experiments have calculated to be Worth $125,000. Dr. Brasch, a member of the In- stitute of Berlin, said radium rays will] be produced at greater strength. This is a disturbing feature for Gamma rays, with the old appara— tus, will kill a man at a distance of 200 meters. Zielinske To Address Engineers Society Mr. W. F'. Zielinske, in his talk to be delivered this Friday, March 13, to the members of the Armour branch of the Fire Protection En~ gineering Society, will speak about spectacular oil fires. In addition, he will also discuss the properties of oil, the distillation process and the precautions against hazards. As a speaker, M12411]. F. Zielinske is considered by the society to be one of the best. He is an engineer for the Marsh 85 McLennan Insur- ance 00., formerly was in the Marines and has taught school in Cuba.

Noniore Try For government lobe Over thirty seniors and one memm ber of the faculty took the Civil Service examinations given by the Federal government on Wednesday and Thursday, February 25th and 26th in the Federal Building downtown. The examinations were conduct— ed in three sections. The first sec— tion was from 9:30 to 1:00 covering optional questions. These ques— tions covered general engineering topics. The second section of the examinations was devoted to op— tional questions on structural en- gineering. Twelve civils and one mechanical tried their hands at this examination. Thursday morn~ ing from 9:30 to 1:00 was devoted to the examination on Aeronautics which was taken by Professor Ja- cobson. There were over a hundred men taking these examinations. or the thirty Armour men taking them there were twenty civils, four elec- tricals, three chemicals, and two mechanicals in addition to Profes— sor Jacobson who represented the faculty. The fact that no questions were asked on theoretical subjects such as Physics, Calculus, and so forth, was a good indication that the government was making the examination easy so as to hire a larger number of men than usual. Except in the case of the Aeronau- tics examination, all of the ques— tions asked seemed comparatively easy. Varied Program At A. I. Ch. E. Meeting A meeting of the Armour Branch of the A. I. Ch. E.,was heldln the Physics Lecture Room last Friday morning. F. B. Atwood, the presi— dent, opened the meeting with an apology for the absence of the speaker, who had been unavoidably detained. Professor McCormaek then filled in the breach by telling of a meeting of the American Safety Council that he attended last Thursday. The experiences that were spoken of during this meeting caused Pro- fessor McCorm'ack to reminisce about some accidents that had happened to some of his own ex- periments. Accidents Liable The laboratories of industrial plants, according to Professor Mc- Cormack, are much more rigid in respect to the wearing of goggles, rubber aprons, and leggings, than the college laboratories. But the industrial laboratories are doing work that is less certain than the schools and is therefore inherently more liable to cause an accident. After a few experiences had been related, the speaker, Dr. Fartin- ger, arrived quite breathless. Of course the lateness of the hour pre- vented the dellverance of the well planned speech that he had pre— pared, but in spite of all difficul- ties the speaker delivered an inter— esting informal talk on oils. At the close of the hour the seniors asked some questions which were cut short by the bell. Eight Men in Elass 0n Airplane Engines Only eight men are enrolled in Professor Perry’s and Roesch’s class in airplane engines. The reason seems to be the extreme difficulty ’if passing the Navy’s physical ex~ amination. A number of men are "low taking this test at the Great Lakes station. The course includes work on Lib— erty, Gnome, Wright-Whirlwind, “ackard and other airplane en— Tines. The hesitation of the men f0 enroll in this class is not due to “he quality of the course, but be— Tause of the serious obstacle pre- sented by the rigid requirements of the government. TALKIES LECTURE DEA W5 CRGWD T0 A. I. E. E. MEEWNG Mr. H. Merrll Smith 01' Electrical Research Products, Inc, the Sound Projection division of the Western Electric Company, gave an address on “Talking Motion Pictures” last Friday at the regular meeting of the A. I. E. E. Mr. Smith first gave a detailed discussion of the method of 1eccrd~ ing the sound on the film. He traced the operations from the stu- dio, through the “mixing panel" to the main amplifier, and through the bridge amplifiers and light valve to the film. Explains Recording Methods The method in which the elec- trical impulses are sent through the light valve and recorded on the two most prevalent types of films, the varying area and varying dens— ity, was explained. The pictures and sound are taken on separate films, and after they have both been developed they are transferred to one film, the sound being on one side, on a strip about a tenth of an inch wide. Projection Described The scene was then changed to the theater, where the reproduction of the sound was discussed. A light, focused to a fine line, is in- terrupted by the markings of the sound track on the film and then falls on the photo-electric cell which changes the light impulses into electric impulses. These audio frequency impulses are then ampli— fied about ninety million times by a series of high-gain amplifiers. Several dynamic speaker units with huge air column horns are used to transform the feeble elece tric impulses into the crashing tor— rents of sound which may be heard perfectly throughout the largest theater. Thespeakefs are elevated to two-thirds of the height of the screen in order that the sound may appear to be coming from the act- or‘s mouths Show Firchriclr Film At A.S.M.E. Meeting An important cog in the machine of iron and steel production and one of the factors which makes the manufacture of modern heat tem— pered alloys possible was seen on a film shown before the A. S. M. E. last Friday morning. This refers, to the modern firebrick, the result of years spent in the mixing and tempering of clays, which make up a firebrick that can resist the elder mous temperatures developed in smelting furnaces and hearths. Shows Detail The process of manufacture was shown in considerable detail and covered the whole business from claypit to storage warehouse through several different types of firebrick, these being made in many shapes and varieties to conform to the contour of the shell in the many styles of furnaces which are used by the industries. Complete views of the kilns were shown in cross section with the circulation of the hot air indicated by arrows which made the function of the whole system very easy to follow. In the first third of the tunnel kiln there is the pro-heating zone in which the brick is gradually brought up to a temperature some- what below that of the next zone, the burning zone. In that zone the temperature is about the same from one end to the other and here the brick undergoes most of the physical and chemical changes which are its character when it leaves the oven. However, that is getting ahead of the story since exposure to the air with a subse— quent sudden cooling would destroy the brick and in order to prevent this, the bricks pass through the last, or cooling kiln in which they drop to practically ambient tem- oerature. The film was shown through the courtesy of the Harblson Walker Company 01' Pennsylvania. Gilee Club [halted 'l'o Tour Europe :John Walker, president of the Glee Club, has received a commu— nication from the University of Michigan Glee Club that should be of much interest to every member of the club. This ambitious glee club, of U. of M, is now at work on a European tour for next sum— mer and invites the ARMOUR Glee Club to come along. Called “Golden Days” “Golden Days” has been chosen as a name for the tour which will sail from New York, July third, aboard the S.S. Republic of the United States Lines. Nearly five weeks will be spent in. Europe vis— itlng places famous in history and literature. London (2 days), Wind— sor, the shakespeare country; The Hague, Amsterdam, The Isle of Marken, Cologne, up the Rhine to Wiesbaden, Heidelberg, The Black. Forest, Lucerne, The Grand Alpine Motor Tour to Interlaken, Mon— treaux and the Castle 01’ Chillon, by the Simplon Tunnel to Milan, Venice, Florence, Rome 12 days), Genoa, along the Riviera to Nice, Monte Carlo, Paris (4 days), Ver— sailles, Ohcrbourg. The tour will end at New York on August 24th. The group plans to rehearse on board ship on the way over. or three thousand dollars are ex— pected as proceeds from European concerts and this is to be divided equally among the members to help ’ defray the cost of the trip which is $585. All those interested should see John Walker of the Glee Club. Fire Protects Inspect 0i! Refining Process Last Thursday the Junior Fire Protects went on an inspection trip to the Refinery of the Standard Oil 06‘ [lady of rnd‘lana at Whiting, 1nd1ana. The plant at Whiting cov- ers over fourteen hundred acres and is evaluated at more than one hundred million dollars. When the group arrived at the plant, they went directly to the main office where they were pro— vided. with a junior Engineer, who acted as a guide. They started the long trip by watching the crude oil coming in from pipe lines that originate in Texas and Oklahoma. From the control room, where crude oil enters the plant, the fire protects started their climb over steps and across fields by going to the room where wax was being re— moved from the crude oil. It was noted that the Fuller’s Earth, that TWO , non Clot» Certain To Win State Meet Almost certain of winning the Illinois state rifle championship the Armour squad is now in the last week of the six weeks of com— petition. At present the squad is 221 points ahead of the second place team, the Shier Legion Post aggregation. The McHenry (111.) club dropped to third place last week after holding second place for four weeks of the meet. In the individual standings S. J. Patla, C. E. ’33, is leading by 25 points. Last week the Tech squad met and defeated a team composed of the best shots of the other nine clubs in the Tribune meet. Morgan Park Military Academy was also a victim of the Armour marksman during the past week, losing to our men by 58 points. Welded.‘ Joints Used in Steel Building “Welding in The Carnegie Steel Building,” was the title of the illus— trated lecture, presented at a meet- ing of the W. S E. by Professor Heald of the Civil Engineering De— partment The lecture, which depicted the construction of the first all .“weld- ed," steel frame building, was de- livered at 10:30 last Friday, in room B, Mission, to an audience of about fifty Civils. ’ The speaker in opening his ad— dress, gave a brief summary of lthe development of electric‘ arc . steel structures. 1 was being used here in a filter: press, could be renewed by heating so as to be used ten or eleven times.

Located in Cleveland al‘hie structure, , .. known . as» the Carnegie Building, was erected at Cleveland, Ohio, by the Carnegie Steel Co. The building is four stories in height and covers a ground space of sixty by one hun— dred and twenty feet. Moving pictures served as posi— tive proof of the Professor’s asser- tion that aside from the greater safety factor to the workers, the main virtue of construction by welding was its lack of noise, for no matter how fiercely the electric arcs glowed, throughout the entire picture not a sound or snap could be heard. Inter-Honorary Men Hon Dance On May I Most of the school intellectuals will be present at the Inter-Honor— ary Dance to be held on May first. Richard Eddy and Fred Attwood, members of the committee say that this date is definite although the place and the entertainment have not been decided on yet.

Need Thirty Signatures to Place Name on Ballot ELElC'l‘lON THlS WEEK The campaign for the election of Junior Marshal started last week with the circulation of petitions for nomination. J. E. Dirkers, F. P. E.; ll. P. Richter, C. E.; R. F. Waindle, M. E., and H. W. Yount, F. P. E., are the men who at press time had almost the required thirty signa— turesfor nomination. There are 168 members in the junior class. Duplicate signatures will be strick- en i’rom all petitions on which they appear. The election for Junior Marshal will probably be held this Thursday, though this‘is not defi- nite. Direct Junior Week The Junior Marshal and the four assistant marshals who are ap- pointed by him have direct control of the Junior Week activities. Plans for the annual Class Rush; setting ‘ of dates for the lnterfraternity track meets and games; and ar- rangements for Open House Night ‘ are seine of the many duties of these men. Junior Week is prob- ably the most important college event of the year and the success depends greatly on the ingenuity of the marshal and his assistants. Setting of the date for Junior Week automatically setsthe date for the Junior Formal as the fol- lowing Friday. ' Overseer Class Rush The freshman— —sophomore class 1:1ish,,:the., annual battle for: class, supremacy which takes place dur— ing this memorable week is over— seered by the marshals in their re— splendent jackets. Reports have it that the competition in the Inter- fraternity Pageant will be unusu— ally stiff this year. Motion Pictures 0n Steam To Be Viewed An opportunity to View several reels of motion pictures, entitled “Steam," will be afiorded members of the A. S. M. E. next Friday, March 13. Animated drawings will be used to explain the passage of water, steam, and gases through many standard types of steam power in~ stallations. These are to be pre— sented first in order that the actual views of the various units, which will follow later, may be better un< derstood. Pictures of modern boilers, the latest superheaters and economiz- ers, and many similar items of equipment will Show these compo— nents both in operation and under construction The Babcock and Wilcox Co. have airanged these films findings Call letters 02?“ Tech Radio .Sfiaf'ion Through the efforts of Professor Wilcox and the officers of the Ar» mour Radio Association, the call letters of the Armour Amateur Sta—- tion were changed from Will“? to WSYW by the Federal Radio Com— mission. The letter Y designates that the station is being operated by a school or college. The 9 indicates that it is located in the Rhith Fed- eral radio district and the W is editoram—chief of the 1931 Cycle, will arrange a schedule for the tak- ing of the outdoor pictures A plat- form will be erected at one end of Ogden Field, and photographs of each class will be taken separately. For this purpose, each class will be divided at random into fora sec‘ em: 11 group. l lions, and pictures will be taken of 1 the international prefix carried by all amateur stations in the United States. The members of the A. R.
