Tuesday, March 18, 1930 PHOTOELECTRICAL CELLS DESCRIBED TO A. I. E. ‘E. MEN Mr. A. J. McMaster, research cn~ gineer for the (1—111 Laboratories, was the speaker at a meeting of the Armour Branch of the A. I. E. E. held last Thursday in Science Hall at 1:00 p. m. Mr. McMaster, who is a graduate of the University of Illinois and whose occupation since graduation has been research work in connec- tion with the photoelectric c‘ell spoke on the construction, charac— teristics, theory, and application of the photoelectric cell. Although the phenomenon of photoelectricity has been known since 1887, when Hertz discovered it, the full importance of it has not been appreciated until recently. In fact, Mr. McMaster said, it was not until the movies had learned to talk that a market was created for the cells. Five years ago it was al- most impossible for a layman to buy a photoelectric cell. Today, however, conditions have changed somewhat and these light-sensitive tubes are now being applied com~ mercially for numerous purposes. The photoelectric cell is used in television, talking motion pictures, lamps and stellar photometry, illu— mination contiol burglar and fire alarms, measurement and control of smoke in boiler stacks, optical counters and a host of others. In the cell construction, he told of the slowness of production and of the great part the alkali metal, potassium, played. Ten tubes a day is a large output at the present time. The cell characteristics were illustrated by the drawing of curves. After a few copies of the G.-M. Laboratory b u 1 letin concerning photoelectric cells had been distrib- uted among the members and after President Dollenmaier had com- mented on the smoker of the night before, the meeting was adjourned. Water Color Exhibit The Tenth International Exhi— bition of Water Colors, Drawings, Miniatures, and Pastels will be held at the Art Institute on Thursday, March 20.

ARMOUR TECH NEWS Country-Wide Exhibit of Architects’ Wort: Beginning March 14 and running for about one week, there will be an exhibition of drawings by the Association of Collegiate Schools of Architecture in the Burnham Liv brary of the Art Institute. The im» portant schools of architecture in the country, including Armour are members of this association. The drawings that will be dis— played will consist of student work of all classes, sketch problems, projects, etc., sent by the various schools as examples of the work. This traveling exhibition is a year— ly event, being sent for about a period of one week. to each of the schools represented. Truckmen to Run Twice This Weed: The Tech track team will com— pate in two track meets this week. Both are to be held at Bartlett Gymnasuim, University of Chicago. The first is to be held at 3:00 p. in. this afternoon with Crane Junior College; the other, a triangular meet with Scars-Roebuck Y. M. C. A. and Chicago Normal College will be held at 3:00 p. m. Saturday afternoon. Aimour has a well balanced team this year and has come through the indoor season undefeated thus far. The two meets thls week, how— 1 Syracuse ended recently with 8'? ever, will put the team to some severe tests. Armour defeated Chicago Normal last year in a dual meet by 45 to 32. Crane was met only once last year in the quadrangular meet held at Chicago Normal College. 1,, Malta Last {fall for Eiaeelrall; 'Candldates The last call for infield and out— field prospects for the 1930 baseball team is made today. All who ex- pect to try out for the squad this season must report at once if they expect any consideration later. The team will go into training in the gymnasium at once. This rul— ing is essential because of the in— evitable loss of time that occurs when men report after practice has begun. The four—day practice has been extended to five days in anticipa— tion of the outdoor work which will get under way in the near future. At present the field is not in shape for such work, the backstop net— ting has been broken in several places. The field is in poor condi— tion due to the action of the snow and ice, but will be taken care of by raking and rolling. The men who report for prac— tice should bring a glove, a sweat shirt and tennis shoes. When out- door work begins spike shoes will be required. R. C. Linnell, ‘29, is working as an assistant chemist with the Illinois Paint Works Company. He has been attending Professor Free- man’s evening school class of En- gineering Economics at the W. S.

He spoke of his great genius and of his unfortunate circum< stances at the time of his death. It devolved on his friends and ad— mirers to take care of his last rites. Thus be emphasized his point that sometimes you only break even. He strove to emphasize the points that you only get out of a thing what you put into it, He ad- vocated simplicity; the less compli~ cated the idea was made, the better it would get across. Mr. Rubori quoted personal ex— periences to prove his point that when the students went out into the practical business world they should know the men with whom they are dealing. He drove home the idea that was the basic prin— ciple of Lincolns‘ life. “If you know you’re right; go straight ahead." Mr. Rubori's talk was received with the utmost of appreciation. Dean Palmer followed with a short talk on the value of friendship among men and the important part it played. Dean Penn spoke on the extraordinary comradeship among the architects. He spoke of the feeling of cooperation that was springing up between the architects and engineers. Dodson, Novy and Ransoll gave several vocal selections and then had to give an encore. The prize which Armour won for having the Page Three best architectural exhibit at the re— cent exhibition held by the Archi— tectural Sketch Club of 011 “ago was presented. It was an etching, “A Rainy Night in Chicago," by Pesehereh. It was a representation of the Palmolive Building. The ex— hibition, at which Armour placed first, will next be shown in Fort Wayne, Ind. After the speeches, everyone went up to the drafting room where an orchestra consisting of Walter And-’ arson, Jed Eisner, Charles Som— mers, Ralph Scarfuri, Martin Myer and under the direction of Dave Balkin furnished music. Carl Schurze gave the vocal accompani— ment. Various members of the classes had little skits to put on, and Mr. Rubori furnished another story before he left. The affair was pronounced to be a complete suc‘ cess and one of the best ever given. Eighteen is the ideal age for uni— versity matriculation, according to a survey conducted at the Univer— sity of Syracuse. Students at that institution believe that matricula- tion at the earlier age keeps men from activities and prevents them from enjoying college. lllinois Trunk Co.
