Plans for the meeting have been left to the committees. Junior WS.E. to Hear about Aluminum Uses Dr. Paul V. Faragher of the re- search department of the Aluminum Company of America will give a talk before the downtown Junior W.S.E. next Thursday evening, dealing with the engineering application of alum- inum and its alloys and will discuss the cooperative program of research. The aluminum industry, young by comparison with the industries built around the older base materials, has from its very beginning followed a policy of cooperating with manufac- turers in the development or rede- sign of their products. Continuous research work has pioneered in the field of the aluminum alloys. The talk, which will be illustrated by lan- tern slides, should be of interest to all members engaged in design in every branch of engineering. This evening Professor W. M. Wil- son of the University of Illinois will speak on “The Current Status of Structural Welding” in which he will show that progress in structural welding is proceeding along a num- ber of lines. New methods of weld- ing are being developed, old methods are being perfected, and welding: is being extended into new fields. The development of types of structures which have resulted from additional research is causing the more em tended use of welding as a means of give a green area or fabricating structures in general. left ear with his right foot.

Spears to Show Pictures for Faculty Club Members Prof. S. M. Spears of the civil en— gineering department will show the motion picture which he took at Camp Armour before the Armour Faculty Club next Friday morning at 10:30 o’clock. two reels of pictures taken at the civil summer camp at Trout Lake, Wisconsin in 1936 and 1937. The films consist of Dr. Copeland to Talk on Electron Emission Dr. Paul L. Capeland has been in- vited to speak before the Physics Col— loquium of Northwestern University, on next Thursday. His talk will be “the Secondary Emission of Electrons from Solids.” All solids when bom- ary emissions. In many cases the emissions are six or seven times as great as the electron bombarding; the sample. This secondary emission in the case of common radio tubes is un- desirable. Two types of tubes, how— ever, have been developed that make use of this phenomenon. The dyna— tron tube invented by A. W. Hull is used in radio work. This type of tube is similar to the old type of screen grid radio tube. The other type called “the electron multiplier," in- vented by P. T. Fal‘nsworth, is used for the amplification of currents in barded by electrons give off secondv photoelectric and television work. Dr. J. S. Thompson will give a entation of student papers, speeches.

Guests Received by Faculty Club The guests from the Chicago sec- tion will be received in the Faculty Club. H. J. Bodnar and E. F. Wag- ner, senior chemicals, will be in charge of the reception. From there, they will proceed to the Student Union whore dinner will be served. At the conclusion of the dinner, student talks are to be presented. Six student papers based on studies made in the Armour chemical engi- neering laboratories will be given by both graduate and undergraduate students. First 8. M. Osri, a senior chemi— cal, will talk on “High Frequency Induction Furnace"; N. Gerber, re- search student with Dr. Komarcwsky, will present “Gas Absorption”; T. M.

Pi Tau Sigma Also Leaves First Floor of Flats Research Foundation have required the few remaining organizations in the Research Building to move. Pi will move, according to present plans, to the fourth floor of the first entrance, Chapin Hall. Part of the remodelling necessary to make these rooms presentable will be done by the school and the balance will be done by members of the fraternity. The Social Science office will be moved to the third floor of the same building in which it is now situated. Extensive remodeling will take place before the move. The space occupied by the Social Science office will be taken by Professor D. P. Morcton and his staff for the use of the AR- MOUR ENGINEER AND ALUM- NUS. The rooms to be vacated by Pi Tau Sigma are to be occupied by the Publicity Department which is now situated in Chapin Hall. With this move all of the vacant space in Chopin Hall will be occupied with the exception of a group of flats on the fourth floor, which are being held in reserve as tentative drafting rooms. As yet, no definite plans have been made as to the dates, or the manner of making the proposed changes. fraternity, Potter Lectures on ‘Contact Potentiais’ Professor J. G. Potter spoke last week before the Physics Club of the University of Chicago on the “Con- tact Potential of Tungsten.” He was the first of several members of the Physics Department who will speak before various outside groups, the basis of the talks being the work that they have carried on in their re- searches. The work discussed by Prof. Pot- ter is important in determining the efficiency of tungsten for use in photoelectric or radio tubes. All of the work in this connection must be carried on in a high vacuum. In order to eliminate any external ef- fects, all of the bearing points and systems of levers must be constructed of glass. Besides this all of the metal, both magnetic and non~magnetic ex- cept the tungsten being tested, is cov» ered with glass. Adjustments and measurements are made by means of outside magnets exerting their effect upon the metal parts within the tube. The talk was illustrated with lantern slides.

Professor Button Travels to Management Convention Professor H. P. Dutton, head of the social science department, left yesterday for the annual convention of the Society for the Advancement of Management to he held in New York City during this week. He will preside at a group meeting- on col- lective bargaining. The membership of the society is composed mainly of consulting engineers, teachers, exc- cutivcs of companies, and others in- terested in the development of plant efficiency and in personnel manage ment. Professor Button also will be pres» ent at a meeting of the American Society of Mechanical Engineers. The proceedings of the asses. usually include papers on new are ccssss and on management methods.
