Vol. XXI. No. 3. Prof. Richardson finest Speaker in Radio Series Tulle ‘Electricity and Therapy’ Topic of Epeech By exaggerating the implications of last Saturday’s radio talk over WCFL it would seem that electrocu- tions are merely beneficial doses of electricity applied with the theory that if a little is good, why then, more is better. It is not to be implied, however, that Associate Professor D. E. Rich- ardson of the Electrical Engineering Department, holds this view. As guest scientist of the program, however, he pointed out that electricity has been applied to the human body in many ways with beneficial results, so much so, that the field warrants its own classification of electrotberapy. There are many subdivisions which Profes- sor Richardson mentioned and ex— plained to some extent which give some indication of the degree to which the art has progressed. Has Many Advantages A very interesting explanation of the operation of the radio knife was given by Professor Richardson. In his words: “This device is called a knife but it does not have a sharp edge. For example, one can cut flesh with the broad side of a small needle or with a wire loop. Practically no pres- sure is required, the only necessity beinz,r guidance. The principle of the radio or high frequency knife is com- paratively simple—where the metal contacts the tissue, there is high con- centration of electric current suffi— cient to raise the local temperature of the flesh to the boiling point. The ac- tion brings about an explosion of cells along the fine edge of contact and the consequent rupture of tissue to form the cut.” No Sliarp' Edge Then too Professor Richardson dis- cussed the advantages of such a knife and pointed out its use in lblood- less surgery in which the electric cur- rent coagulates the blood about the cut. Professor Richardson is well known and needs no introduction to sopho— more electrical students of Armour, (Continued on page four) Seniors Hear Miller 0n “Human Relations’ “To be an executive, an engineer must know materials, the funda- mentals of science, and above all he must know men,” according to Mr. John H. Millar, who talked before Armour Tech seniors on “Human Re- lations,” last Tuesday, Feb. 22. The talk came as the first in a series of four or five to be given for the benefit of the seniors by people con- nected with the business world. Discussing engineering as a pro- fession that has changed from an analytic science, in its early days, to a synthetic one in its modern form, he pictured Caesar as one of our best and earliest engineers. He pictured Caesar as having those qualities that make a good executive, placing spe- cial emphasis on his ability to lead and on his remarkable understand- ing of men and how to control them. Carrying the idea of influencing people’s minds to a conclusion, Mr. Millar gave some hints on that most important phase of their career, get- ting the job. He stressed the idea that the job hunter must first thor‘ oughly acquaint himself with the in- dustry in which he expects to be em- ployed, so that when he is interview— ed he can give reasons for his pos- sible employment that will enable him to convince the employer that he is just the man to hire, and that if the employer passes this chance he will always regret it. Sipp, Neuert Present First of Competive Talks to A. S. M. E. At a meeting of the American So- ciety of Mechanical Engineers on Fri- day, the first two of a series of mem- ber-speakers gave their talks, The speakers are competing in the com- petition to decide who should repre- sent the A.S.M.E. at the convention to be held in Milwaukee on the 18th and 19th of April. Edmund Sipp addressed the group on the subject, “Critical Speeds", and he was followed by Paul Neuert, who talked about ”Refrigerated Trucks.” The delegates sent to Milwaukee will compete with other delegates for various prize“. The convention on most other occasions was held here at Armour, but for other reasons it is to be held at Marquette this year. bliss Yvonne Kevanaugh Steals Play from the Two Males in East By Zorn Let an old-timer tell his juniors the secret of that thrilling perform- ance of “Marriage Proposal,” given by the Armour Players last Tuesday. That pulsating young actress, Yvonne (pronounced Yvonne) Kavanaugh, portrayed Natalia in a fashion remi— niscent of Cornelia Otis Skinner, Helen Hayes and even Katherine Cornell. Supporting her in minor bit parts, were, noticed only by the most observant Armour theatre-goers, John Keane and Jorma Leskinen. Keane hit the heights in the opening scene when his rich young baritone sang out that famous Russian classic, “Ah— Yi-Yuch-Yem." It was so realistic and Russianish that one could just vision the borscht bubbling in Keane’s gullet. Leskinen was good, too, only he isn’t quite familiar with his anat- omy. Your side is not Where you sit on. Flows Through Crowd After the play, this reporter el- bowed his way through a group of crowding, amorous stag-door John- nies, notably Jim Sheehan and Ed Berger, to Miss Kavanaugh’s dress- ing room for his interview. There, still in her very becoming costume, he was greeted by his beaming, radi— ant hostess. After slamming and barring the door to keep out the mass of milling humanity, the interview he- gen. Miss Kavanaugh is a graduate of the Wilson School of Music and Drama and is a teacher of dramatic art. “Oh, the audience,” sighed Yvonne during the interview, “it was so kind and friendly. Never have I performed for so gracious an audi- once. Tom and Jorma must be well- known. The oil's and ah’s the audi- ence gave when they saw them. I am so happy that the presence of a female in the cast wasn’t resented by all those dear boys.” After as- suring her that she was not resented by those DEAR BOYS, I proceeded with my questioning. No Chance, Boys! Miss Kavanaugh is a marvelous cook and is equally adept at sewing. She is not engaged but has many boy- friends. “Yes, I have many boy— friends," stated the young actress, “but I plan never to marry. I will devote my entire life to the legitimate stage.” Her favorite role was that of Meg in “Little Women,” given recently at the Woman’s Theatre. Learning that Yvonne came from Homewood, 111., brought to my mind that our own Prof, Goetz resides in that commun- ity. “Goetz, that’s a familiar name," she pouted. “Oh, of course, he's our new neighbor. He’s the one that never shovels his sidewalk.” At this point Miss Kavanaugh remembered a previous appointment and thought it time to stop. “Why not come out to my home tonight and we’ll finish,” she suggested. After deep medita» tion I accepted, but fired one last query at her. "Oh, there’s only one besides me at home. My little broth- er, but he has the chicken pox.” I immediately. left. Meanwhile, outside in the Audi~ torium a frantic group was trying to (Continued on page four) Armour institute of Technology, Chicago, Illinois Musical Clubs ’ Concert Plays to Near Capacity Audience Under the expert guidance of Mr. Gordon Erickson, the musical clubs gave their annual Goodman Theater concert last Thursday night. The house was filled almost to capacity by the families, friends, and profes~ sure of the members of the glee club and orchestra. Color was added to the program by the fine performance of the soloists, R. Vandckieft, A. Rune, H. Doolit- tie, G. Danforth, T. Yeakle, P. Woods and E. Ratzel. A unique feature of the program was a “gay 90’s” quartet composed of R. Winblad, H. Bodnar, R. Van- dekieft, and R. Conger. The quap tot rendered their own version of “The Bulldog on the Bank” and “Sweet Genevieve." Following the concert, pictures of the glee club and orchestra were taken. While waiting for the photo- graphers to get set up, the orchestra indulged in an impromptu swing ses- sion. Berger and Bodnar Discuss ‘Vacuum Distillation’ Jointly Members of the A,I.Ch.E. at their 10:30 meeting last Friday morning in the Physics Lecture Room heard a discussion on “Vacuum Distillation" by H. Bodnar and E. Berger, senior chemical students. Bodnar described the use and operation of vacuum dis- tillation in the laboratory and indus- try, and stressed the need of such methods when high temperatures cause decomposition. By distilling under low pressure the operation may be carried on at a lower temperature. Berger described this process as used in the glycerin industry, where other methods are more expensive or impractical due to the decomposition of glycerin at high temperature. An open discussion among the members followed the lecture. It was brought out that this will be an important operation in the vitamin field. At the beginning of the meeting Prof. McCormack presented a certi‘ ficate award to E. J. Loutzenheiser, Jr., from the A.I.Ch.E. for having the highest average among the sophv omorc chemical students. Soundleos Sound Movies Feature ALLEE. Meeting Imagine, if you will, sound movies without the sound. This was the unique situation met by the A.l.E.E. at their meeting last week when the sound amplifier of their sound pro- jector failed to function. Neverthev less the show went on, for there were gathered some forty impatient eloctricals who just would not be dis— appointed. Lightning flashed unac— companied by the customary crash of thunder, and lips moved, but Spoke not 11 word. Witty remarks were passed which helped to relieve the monotony of the situation. The films were entitled “A Mod- ern Zeus" and “The Volt Comes Into Its Own.” Lightning research was l the theme of the former film. Grand Ballroom of the Palmer House W. Fuller Discusses Commercral Aviation at W. S. E. Meeting “Engineering Problems in Com- mercial Aviation” was the subject of a talk given last Friday in C Mission by Mr. W. E. Fuller, member of the engineering division of the American Airlines, Mr. Fuller elated with the test department of this organization. First, Mr. Fuller expressed the re- lation of engineering in a modern air» way to the other activities such as operation, maintenance, communica- tions, treasury, and sales. He stressed the fact that engineering plans should give consideration to these, as well as to the purely technical matters. Some functions of the aeronautical engi~ neer are determining airplane load- ing and schedule charts, designing in— struments, instructing employees, and doing test work. Mention-was then made of some of the work being done in the test de- partment. Modern airplane engines need gasoline of such high octane value that Anilol is being mixed with the regular gas right at the car- buretor. A “feathering propeller” has been developed that changes its pitch to 89 degrees in case of motor failure thereby stopping the engine, and at the same time reducing “air drag.” Methods of preventing sleet from coating airplane wings, specifi- cations for new aircraft, hangar con— struction, and routine drafting are other matters that keep the engineer busy. “A prospective aeronautical engi» neer need not ‘ have specialized training as much as a good basic foundation,” advised Mr. Fuller. Only one member of his staff had been specifically trained in this type of engineering.

This will be the third annual conclave of the district composed of the colleges listed above. On Saturday afternoon, a series of speeches will be presented by repre- sentatives of the different chapters. This will be followed by a banquet at which Professor S. F. Bibb will preside. Dean C. A. Tibbals and C. Dunbar will give talks at this affair. Sunday’s program will consist of a banquet at l p. m. at which H. Perlet, in charge of arrangements for the conclave, will act as toastmaster. After dinner entertainment will be a talk by A. W. Meisel, of New York, national president of Pi Kappa Phi, greetings from chapter representa— tives, and an address by H. T. Heald, acting president of Armour Tech. Evening Division of Student Association Holds Election Continuing the vigorous activity with which it was begun, the Evening Division of the Student Assocation held their election of officers last Saturday. The meeting was held under the direction of the temporary Executive Committee at 3 p.m, in the Assembly Hall. The meeting was held on Saturday afternoon, because at this time the greatest number could attend. Despite the hardship entailed in coming down just for the election, a large number of students took part in the selections of officers. The positions to | Movies of improved Automatic Equipment Shown to F. P. E. 5i. Judging by those present, the F.P.E.S. meeting held last Friday was one of the most interesting sessions that has been held in many months. Mr. Barry, Mr. Crandall, and Mr. Quandce of the Rockwood Sprinkler Company showed moving pictures of the Rockwood Company’s most in- genius fire protection device. This new equipment, known as the “H.A. D." unit, is almost magical in its abil- ities to do things automatically. It is claimed that any mechanical action which can be started or stopped by human beings can be operated by the H.A.]D. The films showed several interest. ing applications, among which were the closing of fire doors and win— dows, operating of a water curtain for reducing exposure from other buildings, and the operation of sprinkler systems. All of those present were deeply impressed by the elaborate precau~ tions taken to prevent any tamper- ing with the mechanism. If any part of the system is broken an alarm im- mediately indicates the trouble and usually its location as well. The pictures explained very clear- ly just how this simple device works. A small metal cell is filled with air. When heated the air expands against a diaphragm. This dia- phragm is coupled to a tripping de‘ vice which releases a weight. In fall— ing the weight can he made to do a arge variety of mechanical things. By a simple adjustment the unit can be regulated to the conditions pre— vailing in the building where the in— stallation is made be filled were those of the permanent Officers and Standing Committees. In closing the lecture Mr. Crsndall added a few explanatory remarks. Gay lClaridg-e’s Band to Furnish Music “The best at last" is the slogan of the Junior formal dinner dance to be held in the Grand Ballroom of the Palmer House, Saturday, March 5th, at 8:30 p.m. Atmosphere in the sophisticated mode of a formal event, food in the superb manner that the Palmer House prepares, and music in the sweet, swing style of Gay Claridgc and his orchestra are the features which will. the juniors assure, make the event an epic in Armour social affairs. The junior social committee has spent many weeks of hard work in complet— ing to perfection, even the smallest details in the dance arrangements, and now is ready to show the school the results of their work. Malta Early Reservations Reservations should be made for the affair at the earliest possible date in order that tables of favorable loca— tion may be obtained. Tables, seat- ing ten people, will be placed in three rows across the width of the ball- room at each end. The center of the ballroom will supply ample space for dancing which will furnish entertain- ment between courses and later in the evening. There are still a few tables that may be reserved which will afford easy access to the dance floor and a good view of the proceed- ings. The Palmer House will furnish food of unusual quality in an unusual style. Service will be the best ever seen at an Armour function. Each table will have its own waiter, and the dinner will consequently be served with more rapidity. Salads, desserts, and the side dishes will be served as artistic delicacies. The tables will be set and decorated so as to add to the appeal that food will have for the eye and taste. Harmon- izing with the eye and taste appeal of the dishes, will be the music that Gay Claridge will furnish dur~ ing the dinner hour. Special arrange- ments of soft music will add to the effect and furnish the necessary syn- copation for dancing between courses. Bids on Sale in Lobby Bids will be on sale at almost all hours of the day all next week in the main lobby of the school. The price is $5.50 and includes all tips and other charges. As no bids will be sold at the door, reservations MUST be made early in order that table spaces will be properly arranged. Distinguished guests of the evening will be Dean I-Ieald, Dean Tibbals, Professor Schommer, and Treasurer G. A. Allison. The social committee members for the affair, who are in complete charge are: E. G. Anderson, Chairman; D. W. Jacobson; E. C. Mitchell; and I. M. Footlik. “No details have been overlooked in making arrangements for this event,” says B. G. Anderson, “and I hope we have some real support from the other classes.” C. Harris to Present Slide Rule Lectures in response to numerous requests, Professor Hands will deliver the first of a series of lectures on the use of the slide rule next Friday at 10:30 in Science Hall. This is the third time Mr. Harris has been called on to pass on to the students the intricacies of the “slipstick.” The lectures will be given on alter- nate Fridays, progressing in se- quence from the fundamental to the more advanced scales. A large model of a slide rule will be utilized in the demonstrations, thus eliminat- ing the necessity of owning an instru- ment to participate in the meetings. The lectures will be so divided that each will completely cover one or more scales. The material to be dis cussed will be posted on the bul» letin board enabling the more ad~ vanced students to participate in only the phases in which they are inter» ested. All freshmen and sophomores should attend.
