APRXL 22, 1941 WE lilhdllhé hhlltlh Tfigugl @NA Evflg ”gafilwggfi dill Molded ltlhlmlhlfi At the last meeting of the Fire Protection Engineering Society, Mr. Herbert W. Lange, assistant engineer of the Underwriters’ Lab- oratories, presented a demonstra- tion lecture on extinguishing flame. The meeting was held last Friday at 10 ant Combustion Explained Mr. Lange opened his talk with a discussion of the causes and means of combustion. He pointed out that while lighting a match and blowing it out is a very pro. sale and common occurrence, very few people have ever considered the phenomenon of extinguish merit. The three ways of extinguish ing flamewcooling, smothering and separating flame from the bum- ing matcrial~were outlined and demonstrated. This theory of sop» oration is analogous to an aviat- or‘s diving his plane to keep the fire away from his carburetor and gas tank. This, of course, presu- pososa afire in the plane In his demonstration by cooling, Mr. Lang-go employed a can of par- affin, heated until burning. The can was placed in a pan of cold water. This caused external cool. ing which caused combustion to cease. In another experiment of the some type, alcohol was used instead of parailin. Dry compounds have recently been developed which are most all let-live in extinguishing fires. fin extinguisher is used in which our- bon dioxide ejects a compound in the form of a dust cloud. The dust cloud of this compound in ct“- lectivc in sweeping the flame from the burning surface, and smother. ing the fire. The main col‘nponent of this compound in sodium bicar- honatc. Foam is also a quenching me- dium which provides; a smothering blanket of a certain permanence. If the foam is tough and stable enough, it will provide insulation for the hand against the flame of a blow torch. There is still another means oi putting out lire. That is by means of vibration. A lighted candle placed in front of an auto horn will be extinguisher! when the horn is sounded. However. as the speaker point- ed out, the best way of putting out most tires is still with good (no mo. rlomc hes 'lo present" fluently lzdir, April fill IIT’s Home Economics club will present the Lewis County Fair, something never before, (and never to be) repeated, on Wednes» day, April 30.

Get your entry blank from any Home Ec’cr and get in line for the prize. The department was well repre— sented at the Fashion Seminar held at the Grand Ball Room of the Palmer House. Noted speakers included Joyce Fenley of the Chi- cago Herald American, Nancy Brooks of the Dubary School of Designing in New York, and other notables. The main attraction seemed to be the exhibit by the University of Chicago Home Eco- nomics department with authen- tic representation of historical costumes. Jm W FfillNfll‘il’ Cflljlfifi NEW QBJEE‘ZTWE Another step to provide the en. gineering student of Illinois Tech with the most advanced training that modern industry is constantly calling for is presently being com‘ pleted by the foundry. Less Manual Work The objective of the foundry course is being changed, empha- sizing more the engineering aspect of foundry work and less the man» ual arts connected with it. The course as outlined and conducted comprises the study of the prop» erties of various types of cast metals. their production, use and design. The new equipment of the shop laboratory includes a concentra- tion of physical tests with a mini— mum of actual moulding practice. 'i“estlng of foundry raw and fur ished material, together with the control of molding sands, chemi- cal composition of cast metals, and the most economical and efficient methods in the handling of ma- terial are the operations stressed. Md Equipment Gone A recent clean-up of the labora» tory eliminated much superfluous material. Some equipment was ad tied. Included in the added equip- ment is o tensile strength lest- lng machinea transverse strength testing machine for metals and for sand cores, a gas melting turn. are ioi ferrous metals 3 gas fired oven for cows droid tool crib for the sioilng of patterns and tools. A new moulding bench with hopw porn for moulding sand is con- structed. adding to the general ap- pearance of the laboratory. Prof. Kozaclta, who has direct eul‘lel’vision of the shops. hopes that in the future the foundry wot-it l‘or engineering students will consist of physical and chemical checkup of materials, testing of cost metals, and the best. methods of production. ”MEWS STUllENTS Will"? lil’llflifiillhl Mill last Thursday the physics stu- dents oi Armour had the privilege of viultlng the Ryerson Physics ll emonstration building at the Uni- veilsitg. , oi" Chicago. From early morning till late afternoon the err ginoeera played around with the. early experiments of Newton, Gali— leo and Mlchelnon. The experiments on display were mostly the originals perform~ ed by the early men of Science. Most oi" the fundamental princi~ pics of mechanics, heat, light and electricity were displayed and were of prime importance to the students, since they were able to get a close-up of each experiment in action. Experiments ol‘ interest The demonstrations that attract- ed most attention were those on light. including Michelson's de- termination of the velocity of light, the stroboscopic phenome‘ non and the cathode ray tubes con‘ taining radioactive substances. Many interesting oddities of physical phenomena were on ex- hibition, giving the “brains” a chance to determine an explana. tion. Everyone had a chance to see himself as others see him. This was accomplished by two mirrors placed at ninetydegrees to each other producing an image of an image of the object placed before it. The quizzical engineers kept the instructors busy answering their questions. The responsive reac- tion of the students may result in various other tours of importance pertaining to physics.

The outcome of these two meetings is as yet un~ known, but the representatives of both companies seemed pleased with the boys. Among the more recent firms to visit thee campus were Young Radiator Cu, from Racine. Wis, Presto-Lite Co, and Shell (fill. The latter corporation was so interetlted in two senior chemical engineers that it came back for a second interview The seniors are not the only students who are benefitting from these interviews. Line Material Co. at Milwaukee is interested in obtaining two junior electricals tor summer work. Proctor and Gamble also want a few junior chemical engineers for summer work here in Chicago. One of the graduate students recently se- cured an excellent position with C. Sceinncse Co. of Cumberland, Md. Four men were placed with the Pennsylvania Railroad April 1, ac cording to the Placem .ent Depart— ment. These four men, LeRoy Goetz, Bob Saigh, Eugene Dolley, and Richard Hruda, were in Phil- adelphia Monday, April 1, ready to begin their apprenticeship with the railroad. Their placement was a matter of quicit work, for they weie interviewed by Mr. Grover the previous Wednesday. Mr Grover is; in charge of the main- tcnance department of the Palm nsyivanla Railroad.

Mrs. Car- rol, the Placement Office secretary, feels that her absence is a definite loss; to the oli’ice and to the stu~ dents. Miss Harrls’ work has been excellent. Mrs. Carrol requests that the students please watch the Placement Office bulletin board because she will be very busy now, and unable to contact the students personally. ”lollies filo Investigation hiulllherger ficleocc Dr. Clarence W.

Curtis Hcpperlc and Tom Brown were chosen WEE representatives. Although the term. of the pres» ent board has by no means been completed, it is the custom, of the AIEE to hold an early election so that. the new officers may become more thoroughly acquainted with their new duties. It was announced also that the annual smoker oi" the UT branch of AIEE will be held next 'I‘huro day, April 24 in the Student Un- ion lounge at 8 pm. A. complete and thoroughly interesting pro gram is being arranged for the boys in their yearly gablest. Paul G. Andres, assistant; professor oi’ electrical engineering, will be the featured speaker. Following Mr. Andres address there will be an hour of movies. Refreshments and smokes will then serve to prepare the guests for the Following bull- sessions and battles of pinochlc and contract, for which will be altered prizes. Attention was also called by Treasurer .loo Cor-coral] to the lam ity of many of the members in the payment of dues. A strong plea was insued that the organiza~ tlon be backed more strongly in a financial way by its members, es- pecially in lieu of the heavy ex- penses entailed in providing the exceptional number of outside upcakem in the meetings this year.
