Tuesday, November 8, l938 ARMOUR TECH NEWE ,, Page Three By EUGENE WORCESTER “HISTORY REPEATS itself." So goes the saying, and there is consid- erable evidence to support it. glance into the Orient presents a situation remarkably like that in Eastern Europe over a century ago. Napoleon Bonaparte, Europe's Alex- ander, still unsatisfied with posses- sion of the continental capitals, en- viously looked on Russia's broad plains and seemingly endless fore. 5. But his avidness for indisputable supremacy surpassed his means and ability to achich it. His huge army steamrollercd across the White Rus- sian borders in farmer fashion. But progress was slow for lack of roads. His army, miles from a base, had to live on the fat of the land. Summer passed and autumn with it, and still his objective of Moscow was unat- tained. With the arrival of winter Napoleon was left with burned towns, barren fields and the Siberian blasts. Even before the advancing French, the retreating Russians dc— stroyed all that might offer food or supply to the invaders. History rc« cords that the little Corsican found a conflatrrated Moscow, and returned to Paris disconsolate and defeated. THE CHINESE are using: tactics against their Japanese invaders iden- tical with those practiced by their Russian neighbors years ago. Han» how, the latest Nipponcse seizure, was a prosperous city a few short weeks ago. The Chinese in Hankow, realizing: that the city would fall prey to the Empcrows sons, cooperated with the army and destroyed or re- moved everything of value in the metropolis. Factories and industrial plants were dynamitcd. Power sta- tions and oil stores were mined and burned. The Chinese have deter— mined that their invaders “hall not be rewarded. Japanese capital stands small opportunity to yield return from a mass of smoldering ruins and a boycotting populace. JUST WHAT Japan will gain from her exploits is questionable. She has, to date, buried upwards of 30,000 of her sons. She is finding war and the maintenance of an army vcry ex- pensive. Chinese guerrilla warfare tactics are not helpful to healthy military morale in Japanese ranks. She is decidedly unpopular with the people of the world, although her stock is quoted considerably higher with her Fascist colleagues. History has consistently shown that no one has ever conquered China, but that her would»bc conquerors have all been absorbed. Chinese culture, centuries old, and based on princi- ples sound and extremely simple, has in the past resisted and defended it- self against the pressure of an un- happy, aggrcssivc, and profit-mad- dened world. In spite of “the schemes of mice” and a few men in Tokyo, Rome, and Berlin, she will continue in her culture when these mice are dead and forgotten. m . A London experimentalist has ch velopcd, quite recently, a method for photographing: the fragrance of a lily or the intense odor of camphor. it was well he stayed from Jersey City. or his negatives would spoil with the present stench of her municipal gov- ernment. Frank Hague, whose pres~ out turn implies in 1941. has been her honorable mayor since 1917. do has, in the El years of his office, made Jersey City the country's out- standing example of undemocratic government. Opposition has been quellcd (but not eliminated as yet) by refusal for free expression of speech or press. Court procedures are more formalities. Public meet— ings for others than Hague’s party are forbidden on the ground that they disturb the peace. Hague‘s pri- vately financed mobs of ruffians have broken up previous opposition party meeting-s, and brought on the al— leged peace disturbance. Hague pro- claims a doctrine of Jersey City for industry (and, it might be added, for Hague). When a city official re~ ceives a nominal salary of ten thou- sand a year, and then buys an estate, supports a coterie of satcllitic hench- men (or better, a private little army), and permits and causes con- tinued rank denials of the funda- mentals of the Bill of Rights, it would be well that outside pressure were brought to bear on his little fascist empire of Jersey City by lli’lonerorinm Moth Show or interest Sophomores who have trouble solv- ing problems in calculus, and stu- dents who appreciate clever handi- craft will profit by a visit to the Fall Mathematics Exhibit at the Adler Planetarium. Morton Junior college and the Gary Public schools are spot» soring this exhibit. One model made by Morton Junior college, is in the form of a diorama illustrating the speed of separation of a man walking over a bridge and a boat passing beneath. A second set of. models illustrates the meaning of each step in evaluat- ing a triple integral, used to find vol- umes of solids. This set shows un- usually clever workmanship. Another set of models consists oi? solids suspended in midair, while back of them are two dimensional drawings of the solids with a complete algo- braic solution for finding their vol‘ umc. There are models which illustrate the problem of determining the num- ber of stories a skyscraper should contain to yield maximum income. Other models illustrate hyperboloid wears, select the path of a ditch dug for minimum expense through ground of varying degrees of hardness, find the maximum length of a thin rod passing through two corridors at right angles to each other. Announce Complete Cost ior Players in Latest Production Casting has been completed for the first of the present season’s plays, “Journey’s End,” to be produced by the Armour Players.

This year the membership has been opt-nod to all men iI’Icludinp,r the night School students. By this means, a large membership has been obtained as wcil on many experi- enced The members are di» vidcd into groups, by choice, for the handling; of properties, costumes, pub— licity and stage management.

Secretary of Labor, is a red. The Tribune has further scooped the Dies Committee reports that Rouse» vclt, the New Dealers and all labor chiefs are radicals and communists. In reply it might be said that were this true, our United States would be a communistic government. It is not, by a long shot. The harshest critics of the administration, the in- dustrialists, are ungratefully biting the hand that feeds them. When the banks and industrialists were sick in 1933, Roosevelt came to their aid. Largely due to his policy they have regained health and now they turn from him. With due reserve, it can be said the country was very close to revolution in 1932. Twelve mil— lion unemployed people is a danger— ous element in a country rich in re— sources, but handicapped with self- ish vested interests. Roosevelt is trying hard to solder up the leaky pail of American capitalism, but it is a. difficult task when his support looks for ephemeral fame instead of using- foresight for a planned future. Little Wonder the pail is leaking all around him. I ., . ‘ discussion of the Uses of X—Reyg is Topic tor diff. Armour's branch of the A.I.E.E. presented Mr. H. 'l‘. Trenary of Gen— eral Electric on “Industrial Uses of X—Ray Equipment” in the electrical lecture room last Friday morning. Roentgen in 1892 discovered these hitherto unknown x-rays that could penetrate wood and paper. In 1930 xvray testing of boiler was officially required by the navy. Later it was required in the inspection by the American Petroleum Industry of its boilers. At the present time the X-Ray equipment has been developed to pen— ctr to steel plate 1‘ch inches in thick- {I . For thickness greater than five inches, radium is used as the pene- trating medium. The ability of x-rays to penetrate is proportional to the density of the material. Since platinum is most dense, it should be used as protec- tion from x»rays, however, the cost is so tremendous as to make it pro-- hibitive. Schematic diagrams showing: the use of x~ray equipment was shown. Recent developments include immersion of the x-ray tube to pro- tect the operator and eliminate the necessity of correciion for humidity and‘altitudc changes. Any small dif- ference in density is immediately rc— cordcd on a permanent record. This propvrty is valuable in determining correct procedure in metal casting, since if there are no imperfections the pictures will be shown without flaws. The x—my is the only method of determining: quality of production without destroying the pirce.

The psychological examination was chnngcd to adapt it better to machine scoring, and at the same time a, sixth part was added on number Series. The test can now be divided into two parts. One part contains ithmctic, analogies and number s s This part called Q is heavily loaded in quantitative thinking. The second part, containing completion, artificial language and opposites, in heavily loaded in verbal traits such as verbal fluency and verbal deduc— tion. This part is called 1. As soon as the February grades an, n, inves- tigations will be started to see if the new arrangement has better prcdiw tivc value than the old. The fifth test, general science, which was taken by the last two classes was always regarded as an experimental test. It has been re— piaced this year by a series of short tests on visualization. Research work by Professor Thurston of the University of Chicago seems to indi- cate that the ability to see in three dimensional space can be measured by a test in space of two dimensions. It is known that ability to visualize three dimensional objects is one of the essential characterist s ot a de- sign engineer, and probably of other kinds of engineering also. In the original battery of tests it was hoped to get at least one test which correlated very low with the other tes s when taken by engineer inc" students. The science test did not correlate as low as was expected. but word {Zhemlcuis Witness Motion Picture on ”Eagle Whit-e teed” l l , l l Last Friday morning, the members of the A.l.Ch.E. witnessed a motion picture, “The Story of White Lead," describing the manner in which white lead is produced commercially. The movies were shown by Mr. R. Flood of the. Eagle~Pitcher Lead Co. form of galena, a mixture of lead and loud sulphide, were first shown. The ore is then crushed and passed over a series of jigs whose purpose is to remove all stones which are present in the mined ore. The ore is passed to the furnaces, where. the lead is purified and cast in bars for storage and transportation. Before it is nle in the manufac- ture of white. lead, the lead is first cast in the form of thin metal disks, called buckles. The ~ttuul change from lead to white lead takes place in long corroding houses. Tanbark, the bark of oak trees, is spread over the floor, and pots illcd to one third of their capacity with a 3’s? solution of acetic acid, are placed on top ol’ the tanbark. The lead buckles are then inserted into the pots so as to be directly above the Vapor of the solution. A flooring, with openings for ventilation, is placed over the entire layer, and another layer is built up. This is continued until the ontil'c corroding‘ house is filled. The Lanbai'k, which generates heat and carbon dioxide, acts with the aCid to corrode the lcarl and form white lead. This, the Old Dutch process is com- plete in about ninety days when 70% of the load has bet-n corroded. The pots are removed and the white load, formed in the operation, is crushed and screened to remove any unchanged lead. The finely ground whiti- load i.» then suspended in water and drained off into settling tanks. Water is drained off, and the settled load is mixed with pure lin- seed oil and a small amount of tur~ pcntinc. This mixture is further irrouml and then put up into con. tnincrs. The movie was concluded with a short description of the uses and values of the finished product.

Vocational Interest tests are still being taken by Htudcnts and by per- sons outside of the Institute. So many requests came from women that the worn , test is now hemp; gchn. , people have the wrong imAi I sion that those vocational inter—l est tests measure the interest that onc- h in u particular occupationl This is not true. For instance, cn—l ulnecrs possess certain likes and dis-l likts, not connected with engineer-1 ings in quite a different degree than i the public in general do. What that? means is that from the standpoints of those likcs and di “(its all irinecrs look very much alike and not like folks in the world in general. 11. is hard to give a perfect com~ paI'iH n with more familiar objects, but this illustration might do. If one secs a. man dressed in soldici ’ clothes walking down the street, he says “Tin-re goes a soldier.” In general he is right. l4‘uI'tlicrmore the chances are that such a man likes to be a sol~ r and is happy in his work. 00.» casloi‘mily Lhi tatcmcnt is not true. if a person sees an actor dressed as a soldier on the stage, it does not fol— low that the actor likes to be a sol- dier. That is to say it requires more than the possession of characteristic interests to be an engineer. Home of the things that are necessary are aptitude and personality. Strong: however has found that people who do not lave cliurncterJInterests that charactc 'zed profession rarely make a success of that pi‘ofr... on. Which means in terms of the soldier analogy that if one sees a man on the rot not dressed in soldier’s (fliltl’il‘s, the probabilities are that he is not a soldiur and would not care to be one.

(Confirmed on page site) Methods of mining the lead in thol vocational interest " At the regular bi—wcckly meeting of the F.1’.E.S., held in room A, Main last Friday, the fire protects heard Mr. Abel Gout speak on “Town Classification.” The speaker outlined the points which are of prime im- portance in giving towns their fire.- protection grading- and showed how those points are checked over and evaluated. Mr. Gent is a graduate of the fire protection engineering: dc- pai'tmcnt, and is now with the Illi- nois Inspection ’Burcau. Town grading is one of the most important functions of'an inspection bureau, since the state bureaus rate all towns in their state which have loss than 20,000 population. The num- ber of such towns is quite large, and since they are all I'curaded at least every six years them is a large amount of work involved. Town grading: in of great important be“ cause one of the first steps in rat— int; any piece of property, for fire insurance purposes, is to determine the class of the town in which the property is located. Water Supply important The most important consideration in grading- a town is the public water supply. Next in importance are the fire department, and the public fire alarm system. In addition to these three, the public ordinances [or build~ ing construction, storage of materials, and maintenance of electrical equip» ment arc carefully considered. Actual inspection of fire equip- mx-nt is usually carried out to insure that the pumpcrs and engines are capable of throwing an adequate fire stream when needed. The water sup! ply is c'rcfully inspected an to size and condition of the pipes, pressure at hydrants, spacing: of hydrants, and condition of the pumping station equipment. Water throwing- to. s for both 1' equipment and water sup- ply aic run, using pitol. tubes and other calibration devices to measure nozzle stream pressures, engine rev— 5 olutionn, etc. State Bureau Approves Rates When a town has been inspected by the bureau representatives, their findings are compiled in a detailed report and a rating: is given. A lct- tor of recommendation is sent to the -town officials and suggestions are linzuli- for improving the classifica- tion of the town, and thereby rcduc~ in]; fire insurance rates. When a town makes any such improvements the proposed changes are submitted to the state inI-Ipcction bureau for ap— l proval. ‘ Another of the functions which an linspcction bureau has is the testing of new fire fighting; apparatus prior ,to its acceptance by a city or town. Tests are run for a three hour period I l l ‘at pressures up to 250 pounds per square inch. in recent years many states have boon following the pi". tl(',0 of (Iona ducting a state fire college for fire- mi-n ouch your.

MEETING—~— ( Continued from page one) varsity while inventor Land was a i Mident at that institution. Attract- ; od zmd interested by Land’s early ex- periments, Wheelwright suggested the Land~thelwright Laboratories. That partnership with a student who was to be regarded by his contemporaries as a genius within the next three years was the basis of a research on ganization that perfected Polaroid and now employs twenty top—flight scientists. Mr. Wheelwright is currently en- gaged in a national lecture tour ex- plaining Polaroid and its uses to in— stitutions of learning, lighting and optical interests, and the many busi— ness men who visualize its use in their industries. Other lectures may be given in Chicago, Professor Roesch reports, if the auditorium can“ not accommodate those wishing; to attend. At the last meeting of the society, A. J. Smith of the Calumet Refining Company, presented a sound movie showing; the processing of petroleum from the well to the consumer. The film demonstrated the method of refining used by the Calumet Oil Company. This method, patented under the name of Schulze High Vacuum Process, is unique in that it prevents the oil from reaching the cracking temperatre and decompos- ing: Thus, all the lubricating prop- erties of: the oil are retained. Another interesting portion of the film showed the sludge formed when oil is permitted to oxidize and react with the acids formed in the engine. The vacuum process seems to aid in freeing the oil from this sludge with- out using any solvents in the process. Actual tests showed loss of weight in bearing metals when a corrosive oil was used. The meeting adjourned to the physics lecture room where Mr. Smith demonstrated viscosity tests using the Stevens Viscosimcter with various types of motor oil. 2 at Fire Protects I Hear Lecture Methods oi Dealing with Unruly Fresh Invented When Oregon State College freshmen fraternity pledges decided to walk out on their newly—found “brothers,” they failed to reckon with the pun» lshmcnt for their sins.
