Wednesday, May ll, I933 deals Sciences in @Wm tab Open House wouldn’t be complete without the interesting and instruc- tive exhibits of the Physics Depart- ment. The exhibits will show the simple principals and their applica- tion to modern safety, convenience and sanitation. The experiments will generally be of a more spectacular nature tending to explain simple physical phenomena. The demon- strations will include the following interesting innovations to the subject matter of physics. Liquid Air Demonstrations—Liquid air expands or changes from liquid to the gaseous state when in a hot atmosphere. Gyroscopic Demonstration —— The gyroscope when attached to a rigid body will tend to keep that body in an upright position. Discharge Tube Demonstration—— Electronic tubes display many inter- esting phenomena when in the vari— ous stages of evacuation. Polarized Light Demonstration— Light upon passage through certain substances leaves the surface in only one place. Grating Spectra Demonstration —~ Finely ruled metal or glass has the property of breaking light up into its characteristic spectra. Bernoulli’s Principle — A demon- stration of the principle that allows ballplayers to throw curves. The in- terestim,r phases will be demonstratr ed with a ball on a jet, Flcttner Ro— tor Ship and Venturi Tubes. Photo-Electric Cell—Will include applications such as the Photo-Thy— ratron relay and the PhotovElectric organ. Electromagnetism m Instrumental principal which governs the opera- tion of many modern electrical pieces of apparatus. Brownian Movement—A demon- stration to include visible movements of the action of molecules upon par- ticles in solution. Radium Exhibit —— Demonstrations of the Geiger Counter, Radium Ap- paratus and samples. These are but a few of the entertaining ex- hibits which will greet the visitor to the Physics Department. Display Electrochemistry in Theoretical Chem Lab The physical chemistry laboratory will tonight oil’er Open House Night visitors a cross-section view of the P Chem laboratory course at Armour Tech. Emphasis will he placed upon the electrochemical determinations performed during the second semester of the junior year although some of the first semester projects will be per- formed, and an illustrated student’s lecture presented. Electrochemical determinations to be presented are single electrode po- tentials, hydrogen ion titration, indi~ cator constants, differential electro— metric titration, and conductivity. Electrochemistry of vital importance in the chemical industries and is a major subdivision of physical chem— istry. The experiments performed il— lustrate the fundamentals of the sci— ence. Time reactions, series distillation, surface tension, and the electrolux principal of freezing; by evaporation comprise the second phase of the phy» sical chemistry exhibits. The properties of solids, a part of the physical chemistry laboratory program, will be illustrated by a stu— dent lecturer and demonstration in classroom “A” on the fourth floor.

Metered @ehvers Tails over Wfiiiic we @pen intense A special broadcast relative to the annual Open House at Armour Insti- tute of Technology was presented over station WCFL Saturday, May 7, in place of the regular applied science educational broadcasts spon- sored by Armour at 6:15 P. M. Professor David Penn Moreton, Director of Public Relations, member of the Institute faculty in the elec— trical engineering department, alum- nus ol‘ the Institute in the class of ’06, and with the faculty since his graduation, was guest scientist. His combined experiences with industry in the design, manufacturing and ex- ecutive branches enabled him to dis— cuss thoroughly with Alexander Schrciber the topic for the broadcast, “What Is An Engineer?” To Prof. Moreton, the engineer is a person who works with the forces and products of nature in or— der to serve man and to advance civilization. In order to render this service, the engineer must be versed, not only in the theory of a partic— ular study, but he must also be versed in the methods of practical application of that study so that mankind may profit thereby. Funda- mentally, the training of a. student engineer, is to the end that he may be able to successfully apply theory to practice. "The visitor at Open House,” he said “will see displays calculated to give an insight into the fundamentals of the engineering profession,” what he termed the backbone of modern civilization. The exhibits illustrate step by step, the manner in which this technical knowledge is gained. In the basic sciences, such as mathematics, from elementary alge- bra to integral calculus and differ- ential equations, and physics from Newton’s three laws of motion.” Next Saturday, at 6:15 o’clock, Alexander Schrcibcr will present an- other broadcast, relating to the field of civil engineering. M. B. Wells, Professor of Civil Engineering at the Institute, will be guest scientist. The subject under discussion will he “Lighter Than Air Craft.” lireahman Students' Exhibit Stresses Molecular Theory Students in the freshman labora- tories, under the direction of Dr. Van Atta, will present an interest ex— hibit on the molecular theory-to- night. Experiments on diffusion, effusion, and osmosis will be per- formed to show their significance to the molecular theory. An attempt is being made to demonstrate the Brownian movement of the molecules on a scale which will permit visitors to see this interesting phenomena. Augmenting these experiments will be a novel exhibit comparing»; the alchemist shop and a modern chem- ical laboratory. Equipment used in the alchemist shop will be contrasted to that used in our modern labora— tories. Freshman students will also per- form various experiments from the regular first year chemistry work. A large number of these will be devot- ed to quantitative and qualitative analysis. A large part of the display will be devoted to chemical reagents in co— operation with many chemical sup— ply houses. These reagents will vary from the most common type to some of the rare products. Time Motion Study Exhibit- Ey Social Eider-ice Students Time and motion study will form the basis of the social science ex- hibits in C mission tonight. The fea— ture of the exhibit will be a movie illustrating time study methods but this will be supplanted by charts and diagrams relating to social science and economics. The motion picture of time study was made in part by students tak- ing the course and gives an idea of how a problem in motion study is solved. With the movies will go a running explanation of the work being done. The charts and models that will be exhibited together with the movies will serve to round out the picture of the type work being done in this field of social science, and will also give some idea of the Evening—Junior Dance. Wm work that is being done in account- ing, economics, and in the special .. courses offered in the department. ARMOUR TECH NEWS Radio Club Members Show Student ‘Work tor Visitors Opening their rooms to the public today, the Radio Club will present an extensive display of their equip- ment. The outstanding feature will be the exhibition of their two way radio transmitting system. In this manner they will communicate with the electrical laboratory in the main building throughout the day. The club’s rooms are located on the third floor, second entrance, in the Physics Building. The radio system operates on the five meter amateur band and enables the club to contact points about the country. Because of electrical dis~ turbances about the school, however, the transmission will be confined within the campus. civil Engineers Have Extensive Open biomass The main exhibits of the Civil Doa partmcnt are located in the south end of Chapin Hall. This department has as its branches structural, rail— way and highway, and sanitary on“ ginccring. Each of these branches features displays. Sanitary engineering has the fil- tration laboratory at the extreme south end of Chapin Hall. This lab- oratory occupics three floors and the basement. It is completely equipped to treat every type of raw water on a large scale. The water when com- ing from the source is first treated with chemicals and passed into large tanks in order to give time for the reaction to take place. When the im- purities have coagulated, the water is passed through the sand and gravel filter and kept in the storage tanks in the basement. This plant is capable of handling 10,000 gallons of water a day, which is sufficient to care for a fair sized town. The structural division features a series of models and drawings of va- rious structural members and bridges. The soil mechanics labora- tory which is connected with this div vision is designed to make tests on every type of coil. lUNIQR DANCE-- (Coniimwd from page one) den rapidly springing into bloom and spacious vinevcovercd veranda. With a spring moon in the skies, these should prove excellent hunting grounds for Dan Cupid. Should weather permit the outdoor dance floor adjoining the garden will also be used. ‘ The Olympia Fields Club is lo~ cated on Western avenue near Lin— coln Highway, 3.6 miles south of I—Iomewood. The club may also be reached conveniently by means of the Illinois Central Railroad, the sta~ tion being located some three hun- dred feet from the club entrance. To avoid all confusion the committee has had a map drawn showing the location of the club and the various routes by which it may be reached. Copies may be obtained from the Registrar’s office. SEHGLARSHW EXAMS—— (Continued from page one) Chicago and suburbs, examinations will be given by the high school principal, and interviews by a repre— sentative of Armour, (alumnus) in their vicinity. Approximately 120 students have been interviewed and have presented their applications. Judging from this, there will probably be about 200 competing for the scholarships. Groupie hob Again lies Wind Show The organic chemistry laboratory on the 4th floor, Main building, as in previous years, will present an club- orate demonstration on Open House Night under the supervision of Dre. B. B. Freud and R. Bl. Manley. This exhibit has gained wide prominence in previous years for the manner of presentation is unique in that prepa« rations for its showing are made many months in advance. A central theme is chosen around which the motif of the exhibit is planned. This theme represents a particular por— tion or branch of modern chemistry and its application to industry. A formal organization is formed by the organic chemistry students who perform their duties under the guidance of a student director, J. R. Meyer. Each student has been re- sponsible for the successful comple— tion of one experiment. These fac- tors, coordinated with the central theme, permit a well balanced and interesting presentation. Color in chemistry, which was the theme last year will be augmented this year by a new and modern sub- ject, “Man Made Molecules." Mole— cules not found in nature are “built” to man’s specifications. Color, odor and physical and chemical properties may be imparted to the molecules by the chemist in the laboratory. Electorate tab ides Varied Show At least a million volts of high he quency electrical energy wrll leap across the seven fool, spark gap in Armour Mission tomorrow as visitors look on. The “electrical engineer” type of person will of course never tire of the stream of sparks in Mission at all, but if he does, he can come into the Electric Laboratory on, the second floor and. watch Jacob’s Ladder, a 50,000 volt are between salt water streams, or “red hot" wires sizzling under water and yet continuing; to glow. To the Romeo type: Don’t fail to bring your girl friend. In a quiet ro- mantic corner of the laboratory the Kisstchter will be set up. The “safe cracker" type will be especially interested in modern vault protecting systems. A grid glow tube relay detects the mere presence of a person due to his “body capacity,” and rings a warning bell. For surgeons and medical students the electric knife and the high fre— quency “fever machine" will be dem- onstrated. Lawyers and liars will enjoy the Emotional Stability Detector, a vari— ation of the well known Lie Detector. Marksmcn can test their skill on a rifle that does not shoot bullets. Only a beam of light is used; a photoelec- tric cell concealed in the bulls—eye tells when a hit is made. The television laboratory will fea- ture a pair of television telephones. This is the type that is now being; used in foreign countries and should illustrate the great possibilities open in the television field. Among- the other exhibits of the electrical department are: operation of dial telephones, stroboscopcs, clccn trical cost meters, the electric candle, the photo»chemical switch, magnetic field experiments, etc. The dynamo laboratory on the first floor will be running full blast. Amateur radio station, WQYW, will carry on two way communication with transmit. ters in the electrical laboratory. Moths Exhibit Musicals” Work Prominent among the exhibits in the open house program are the dcm— onstrutions offered by the various laboratories and shops of the Me- chanical Engineering Department. In the Material Testing Laboratory, which is located in the basement of the Main Building, various testing machines will be shown subjecting concrete and steel test pieces to com— pressivo tension, hardness and tor- sional tests. A testing machine of 200,000 pounds capacity will be foa- tured. The hydraulics laboratory will demonstrate hydraulic motors, liquid flow measurements and air circulation equipment. Steam Turbines and Pumps Steam laboratory exhibits will in- clude steam turbines, air compressors, a Corliss engine, injectors, surface condensers, a Marsh type pump and a Wach engine. In the oil testing laboratory frictional and “oilyncss” tests will be made. Problems aria— ing from heat transfers through pipe coverings and insulation materials will be shown in the heat transfer laboratory. These are located in the Research Laboratory Buildings. North of Machinery hall on Fed~ cral Street, the Automotive labora- tory will operate many recent models of famous Diesel motors. A horse- power test will be run using a 1937 Chrysler Royal engine on a Midwest Potential dynamometer. Featured will be an RCA. Cathode compres- sion pressure indicator which will be mounted on a Fairbanks Morse “packaged” power plant. This dc» vice receives the pro ure changes from a variable quartz pressure cry" stal which is then amplified 100,000 times. A cutaway automobile chas— sis, lubricant testing machines, and various orifice tests will be shown. Shops in Operation Machinery Hall will have most of its shops in operation. The machine shop will illustrate the use of the lathe, milling machine, gear cutting, Page Three F. P. if. Students Show New inventions According to chairman Howard Downing, the Open House exhibit sponsored by the Fire Protection En— gineering department will be one of the most interesting that has ever been presented. The apparatus dis— played will cover almost every phase of Fire Protection Engineering from the problems concerning exposure of buildings to putting out fires. The small model village that was set up for Open House last year will be on display again tonight. This toy town has in it all of the things that are taken into account when a building; is given its rating for the insu'ance companies. There are small structures situated on several different streets, all completely equipped with curbstones and fire hydrants. The use of the village is a graphical means of demonstrating the fire hazards that exist from ex- posures, communicating bridges, and types of building construction. This village makes it possible for the un- initiated visitor to understand with ease the rating principles. In addition to the model village there will also be a complete assort- ment of fire extinguishers on exhibi- tion. The standard soda~acid type will be shown in several of the ap- proved sizes and their construction and action will be explained by the men on duty. Along with the soda< acid extinguishers will be the carbon dioxide pressure type, used where gasoline, electrical, or oil fires are a hazard, and the pyrene hand extin— guisher for home use. Finally there will be the foaming type such as is used at the present time in the chem— ical laboratories. Along the line of public protective measures there will be several pieces of equipment that are used by the Chicago fire department. These will include an alarm recording device, one of: the most ingenious inventions of our time, and one of the swinging radiator lights that have been placed on all of the regular fire department vehicles. Finally, there will be the usual siren, one of the big noises of Open House night. The private fire protection devices of automatic sprinklers will be prom— inently displayed. grinding, boring and shaping ma- chines. In thc welding and heat treating- shop, flame hardening of gear teeth and all types of electric arc and gas welding will be shown. Many special welding machines will also be shown. Among these are a pipe cutting and welding machines, radial and straight line cutting ma— chines and a special alloy surface welding device for coating hard wear- ing edges and surfaces with a spe- cial hard rod. Foundry work will include sand testing, mold and core making. Aluminum castings will be poured frequently during the afternoon. Over two thousand pounds of cast iron will be poured during the evening. MAJ. GEORGE GRADUMED FROM TH Sl’lY OF MICHIGAN AT THE AGE OF 93! AT ZI HE WAS WITHIN A FEW WEEK? OF RECEIVING HIS DEGREE.
