Tuesday, January 20, 1931 Chemicals Hear Tall: on Celoten Products E. C. Lathrop, Research Director of the Celotex Company, addressed the Armour Branch of the A. I. Ch. E. last Tuesday morning at 11:30 in the Physics Lecture Room. He presented a talk that illustrated many of the problems that con— front a chemical engineer in the held today. In order to better il- lustrate his many points he showed a reel of motion pictures. The motion pictures showed the group the various steps in the manufacture of Celotex from the time it is cut on the sugar cane plantations until it is packed into box cars for shipping to the differ- out parts of the civilized world. Dr. Lathrop passed out samples of Celotex that carried a printed slip telling of its insulating properties. The data for these sheets was com- piled by Professor Peebles of the Institute. Professor Peebles has made many determinations of the heat resisting properties of the various types of Celotex. Isadore Abraham, ‘31, is being con— gratulated as the most recent reci- pient of the Schmier-Kemiker tro— phy. The accomplishment bringing him this honor is a reduction expe- riment which gave a beautiful spla‘l;« ter finish to an otherwise mono- tonous wall in the senior chemistry Electricals Maire Trip To woodman Factory (Continued from Page 1) which the commutation surface is turned down. Armature core lam- inations are stamped in one opera- tion by a large machine and then placed on the shaft and fastened. After the windings are put on, the armature is tested for static and dynamic unbalance by a machine which gives the location and the amount of any unbalance in inch pounds. The baking room, kept at a temperature of 200 degrees F. for drying the armatures, proved too hot for a few men who entered. Motors for locomotives which travel through low passageways are made very compact so that the total height of the locomotive is only eighteen inches. The motors used in gaseous mines must be totally enclosed, according to Bu~ reau of Mines specifications, so that any sparking at brushes or controller does not cause an ex— plosion. Since the use of trolleys or third rails is out of the question for a similar reason, a reel, at— tached to the rear of the locomo~ tive and Wound with a feeder five hundred feet in length, pays out the cable as the machine leaves the entrance of the mine. When the trip was finished, at about 3:30, the men left the plant after thanking the guides for the ARMOUR {TECH NEWS Rivetless Ship built '65,:ng @f The Earth” at Charleston, 5. 6. To g e A. C. 5.

The Armour Tech News was put on a compulsory subscription basis on Thursday, December 18, 1930, by unanimous vote of the student body. . . The placing of the Armour Tech News onthis bas1s came as a result of several conferences 'in which various plans were dis- cussed by the managing board of the paper and the officials of the Institute. As a result of these conferences, 1t was decided to put the following motion before the student body: “That one dollar be added to the student activity feeeach semester for the creation of a fund to be used in operating the Armour Tech News.” This was the motion carried by unanimous vote of the assembly. The immediate need for this move was the accumulated debt with which the News was burdened. From figures obtained through a study of the operating expenses in the past and the probable expenses in the future, it was seen that it_ would be impossible for the N cws to continue on its original basis. The first use to which this added income will be put will be the wiping out of this debt of past years. The next act Will be the improvement of the content of the paper in 9.134%” make it com- interesting experience. pare favorably/with student .. , , .. lar size and type to Armour Institute. It is not the intent of the staff to squander the money in putting out a paper which would be beyond the needs of the student body. At the end of the first semester, Spring 1931, it is the intent of ) ‘ the staff carefully to examine the expenditures and income of the paper with the idea in mind of reducing the subscription price to $.75 a semester. This price is a fairer one to the subscriber in comparison with the policies adopted by other institutions. It is believed by the staff that it is possible to operate the paper satis— factorily at this subscription rate ($.75), and quite possible to make a profit. Any profits which accrue from year to year shall be maintained in the Armour Tech News Fund until’of a Size, which in the op1n~ , ‘ ion of the staff and their faculty admsor, is unwieldy and unnec- cessary to maintain. In such an instance, the staff shall confer with the officials of the Institute regarding some plan by which a portion of this amount may be turned over to the A. T. A. A. FRED ATTVVOOD.

Kellogg of the Northern Illi- nois Public Service Co. addressed their meeting last Thursday even— ing at the Engineers’ Building. In presenting his subject, “Power Plant Operation," Engineer Kellogg first stressed a side of his topic the importance of which is often overlooked, that of personnel or- ganization. Then turning to the mechanical side of power plants he outlined various factors indispen— sible to the efficient operation of boilers, turbines, and other equip— ment. His points were well backed up with numerous curves, careful] compiled data, and the necessary statistics. NEW hail/KS NONoTECHNlCAL Talks and Talking Kleiser, Grenville.
