PROBLEMS OF INDUCTION MOTOR ENGINEER ARE GREATLY VARIED
Large Number of Steps Are Necessary in Designing, Constructing Induction Motors Which Are Being Used a Great Deal Now.
(Editor’s Note: The folowing article is written by a graduate of Southern California and was given before the Schenectady Section of the A. I. E. E. at the Sympasium meeting. K. C. Mobarry is now a leading induction motor expert and his article is regarded as a learned discussion oil the subject.)
BY K. C. MOBARRY
A test man entering the induction moter design department promptly becomes known as an “Induction Motor Engineer. He soon discovers th:,t if he would live up tc that name he must waste on time in getting down to work*
A majority of the young engineers in the department are on the department plan. That is, they spend a
period approximating a year studying departmental routine, designing methods and some of the problems encountered in building and operating induction motors. Thus they law a foundation for their future work in the industrial or commercial departments. Occasionally one of these men finds some work in the department which is particularly attractive to him. In addition to these men, there is from 'time to time a young engineer from the advanced course in - engineering who visits the department for about three months to study methods of design and special problems.
An engineer on the departmental plan, whether he moves on to another department or remains permanently in induction motors, has a rather well defined channel of instruction before him. His work progresses through five major steps. It is my purpose to show briefly the kind of work encountered in each of these steps.
DESIGN FORMULAS
The first is an introduction to design formulas. Here it is found necessary to translate the greater part of the school-learned technical knowledge from the sketchy and abstract form of the average class-room to a more physical and concrete form suitable for practical work. ‘In other words, the engineer must learn the language of the machinery which he is to build. With this purpose in mind he is given the formulas used in calculating the design and the characteristics of induction motors, and spends several weeks in finding out where the^e come from, what they mean and how to use them. If he simply commits they to memory, without attempting to see their physical meaning, an induction motor will mean nothing to him but two sheets of formulas. In order to get future problems fully prepared he must master the fundamentals from which these formulas are derived.
After a few weeks of such study our young engineer enters the second period which we may call requisition designing. When a motor, ordered by a customer, is not standard, it is nec-esary to determine how the motor should be built before instructions can be issued to the factory. The requisition designing engineer must decide.:
1.	The size and kind of frame this motor should have.
2.	The size of punchings.
3.	The proper winding required to give the desired values of torue, efficiency and power factor.
The first three items, namely the frame, punching and slots, can usually be determined from past practice. That is, the horse power and speed of the motor determine which one of a large variety of frame sizes to use, while the type of service will point out whether an open, closed, or artificially ventilated type of construction is proper. Similarly, the number of poles and frequency determine the punchings and slots. The chief problem, then, of the young engineer working on requisition designing is to choose the proper winding to give the desired characteristics. In this, too, he is guided to some extent by past experience. He knows that he must keep within certain limits and so, guided by these limitations he chooses

First Big Football Game Will See Band Wear New Outfits.
The Trojan band will blossom forth i in uniforms previously unheard of on the occasion of the first big football game of the season is the announcement of Bill Ward, manager.
“Realizing that the sensations caused by the appearance of the band on previous occasions must be surpassed, we are endeavoring to create something that will be both original and striking,” stated Ward.
Contacts have been made with high school throughout Southern and Central California with the result that from sixty to seventy of the most prominent musical graduates will make Southern California their Alma Mater, and will further augument the ranks of the Trojan band.
According to Ward, the band will make the trip to Stanford and will be present at all Coliseum football games in an execution of many difficult features.
The band will be composed of one hundred and seventy-five musicians, and will be under the direction of Harold Roberts, director of Musical Organizations at Southern California.
FROUC FOR WOMEN DRAWS HUGE CROWD
The Midsummer Frolic sponsored by the Educational Fraternity Pi Lambda Theta, for the women of the Summer School was a success, from the standpoint of numbers at least. Two hundred and forty-seven women and faculty members attended the good time held an the Edgewater Beach Club at Santa Monica. A program of activities had been planned for the afternoon, consisting of a series of special “educational” classes under the direction of the sorority members, a track meet between the faculty and students, a program of dances from students in the Physical Educational department, and oral readings by Miss Clara Sharp. The student body easily defeated the pedagogues in the meet, also winning the “bawl game” which concluded the day’s events. The faculty team consisted of Dr. Lefevre, Dr. Ruediger, Dr. Crawford, Mr. Klopp and others. Dr. Lefevre’s efforts to whistle were much enjoyed. Several guests enjoyed swimming in the pool and surf.
A dinner program served as a commencement exercise for this special summer session. A loving cup was presented to the student team, and ribbons to the meet winners. Diplomas were presented to those completing the stunt course, earlier in the day, and several “honorary degrees” were presetted. Dr. Rogers presented the class and greeted the guests. The commencement addresses were given by Dr. W. C. Ruediger and Dr. Edward ilims. A musical program and community singing under the direction of Miss Winifred South were presented during and fallowing the dinner. Miss Agnes Ring hein was the accompanist and piano
soloist. Mrs. Floy Bower was the so-a winding, and with the aid of the prano soloist and Miss South played

the violin.
During recent years numerous bodies and groups of students and faculty members have done much to bring recognition and fame to Southern California. To the average individual in the everyday walks of life, the athletic success achieved would be symbolic of a university’s gains. The Administration, however, knowing full well that no institution of higher learning can exist and maintain standards for which it was established merely on athletic powers, has encouraged dramatics, debating, band and glee club wrork and sll activities wThich further the social, moral and educational life of the students.

During the past five years which have been the big milestones in Southern California’s advance, debating has been much in the limelight. Trojan debate teams have graced the platforms of leading colleges and universities throughout the nation. These teams have taken trips which have led to Southern states, the Atlantic seaboard, New England. Canada, and practically every State west of the Rockies. During the five year period they have engaged in nearly two hundred contests, winning the major portion. Until a defeat this year, Trojan forensic teams had won nineteen consecutive decision contests.
* * *
Coach Alan Nichols has been handling the Cardinal and Gold teams during this reign of almost unequaled success. He took debating, which amounted to little, which aroused no interest, and built it into an inter-collegiate sport which ranks with the best. Alan Nichols is a lawyer in Los Angeles, but devotes a large part of his time to debating and oratory. For the past two years he has been in charge of the National High School Oratorical Contest, and two years ago was director of a similar contest carried on among colleges.
Using a squad system, Nichols develops a powerful team, which is well fortified with ‘‘second string men”. These debaters learn his system, work on briefs, develop cases, engage in' minor debates, and prepare themselves for future varsity debating contests. The system used by Nichols has enjoyed marked success and is widely being adopted in debating circles. Southern California has jumped into national prominence since Nichols took over the debating duties, and for the last two years leading debates engaged in by Trojan teams have been used in the book of Inter-Collegiate Debating.

DR. R. D. HUNT RETURNS FROM WORLD TOUR
Dr. Hill, Other Member of Party, Will be on S. C. Campus Next Week.
Dr. Rockwell D. Hunt, Dean of the Graduate School of the University of Southern California, returned to the Trojan campus yesterday morning (Monday) after an absence of eight months which were occupied with a trip around the world. Dr. Hunt was accompanied by Dr. John G. Hill, professor of Biblical Literature at S. C., who is now attending a conference on religious education at Lake George. Dr. Hill will return in a week.
“One of the most interesting features of our eight months jaunt around the world,” says Dr. Hunt, “was the numebr of University of Southern California alumni and former Trojans who greeted us at all parts of the world. We were greeted by groups of former Trojans at Hawaii. Japan, China, India, Egypt, and Italy, and saw at least one former Trojan in every country we visited. We were impressed by the splendid loyalty and and courtesy shown us by Southern California alumni in the Orient.” Dr. Hunt stated that in the most part the former Trojans encountered on the trip were natives of the countries visited but in some instances they were Americans.
Both professors were on sabbatical leave from the Trojan institution for the eight months, and while on the trip Dr. Hunt made a careful study of economics and political conditions in the various countries while Dr. Hill made a study of religious and philosophical conditions.
While in London both Dr. Hill and Dr. Hunt served as delegates from the University of Southern California to the Centenary Celebration of University College, London, an impressive affair which was formally opened by the King and Queen of England.

THREE CONDUCTORS BORN IN FOREIGN LANDS TO LEAD
First Week of August To Have Noted .Leaders in Hollywood Bowl.
Three guest conductors — all well-known in the Southland — are listed on the Hollywood Bowl calendar for the first week in
August.
While attendance was greater in July than any month in Bowl history, according to Mrs. Leiland Atherton Irish, general chairman of the concert committees, the second month presages even larger crowds at the “Symphonies Under the Stars.”
The first conductor to wield the baton over the large Hollywood Bowl orchestra on the first Bowl night in August is Modest Altschuler, who will direct on Tuesday, August 2. Altschuler, Russian born, was founder and for twenty years conductor of tbe Russian Symphony orchestra in New York. He is credited by some of the foremost critics with being the man who, almost single-handed, has given to Russian music the popularity it enjoys today. His host of friends in the Southland, where he has resided for several years, eagerly await Altschuler’s “Russian Night” in Hollywood Bowl.
■fhen comes that noted composer and piano virtuoso, Ossip Gabrilow-itsch, to direct just two nights, August 4 and 5. Gabrilowitsch has been conductor of the Detroit Symphony orchestra for the past nine years, has appeared as guest conductor with many of the omportant orchestras, and has concertized widely as a pianist, appearing many times in the Southland. Not for four years, however, has he appeared at the Bowl. His two concerts are the generous' gift of Mr. and Mrs. Edward L. Do-heny to Hollywood Bowl.
Adolf Tandler, a native of Vienna, who has chosen Los Angeles as his home, completes the trinity of conductors for the first week in August. Tandler will direct a program of the light and melodious music of his native land on “Viennese Night,” Saturday,, August 6.
The feminine touch to the Bowl programs this particular week will be given by that charming young lady with the powerful voice, Carmela Ponselle, who will appear as soloist on Friday night, August 5.
Sister of the illustrous Rosa, who received such a grand ovation when she appeared in the Hollywood Bowl several seasons ago, Carmela Pon-sello, an artist who stands suprem1© in her own right, makes her western debut in Hollywood Bowl.
Miss Ponselle's appearances in the east, where, since tbe first of January, she has sung thirty-nine concert engagements, and ten extra with her sister Rosa attest her extreme popularity as a soloist and presage rare entermainment for Bowl devotees on next Friday evening, when she sings arias from Verdi's “Aida,” Puccini’s “Tosoa,” and Bizet’s “Carmen.”
Parking space at the Hollywood Bowl has keen enlarged this year, so there is no more “parking” problem to worry the motorists. Also, the Pacific Electric has increased its car service during the hours before and after the concerts, making it very convenient for everyone to attend the Bowl concerts this year.
The larger audiences this year over previous years attest the fact that the Hollywood Bowl is fulfilling, more than ever before, the desire of its founders “to give great music to great masses at small cost.”
Added to the spiritual enjoyment, the physical pleasure of restful evenings under the stars, and relaxation from daily toil in these balmy California evenings out-of-doors, the Hollywood Bowl Concerts are entertainment supreme.
Programs for the week follow: (Continued on Page Four)
