Page Four==: THE BATTALION, College Station (Aggieland), Texas, Tuesday, April 15, 1947 Columbia Chem Prof Addresses Society Speaking on the topic “Mono- dispersed Colloids and Higher Or- K. LaMer of the Columbia Univer sity Department of Chemistry ad dressed the A. & M. Section of the American Chemical Society Sat urday night. Illustrating his talk with dem onstrations, he discussed the Tyn dall effect as a means for rapid determination of particle size in smokes and colloids. Dr. LaMer has been connected with Columbia University since 1919 in the Department of Chem istry and has been a visiting pro fessor at Northwestern University, Stanford University, and Pennsy lvania State Colleg. —WALTON— (Continued from Page 1) called “secret files” (“They are not particularly secret/’ Walton remarked) the former president quoted Dean Potter as recommend ing “Unless you have a million dollars, don’t spend more than $25,000 on a wind-tunnel. All you can build is a toy, and you’ll be wasting the taxpayers money.” Hardeman charged that this rec ommendation was hidden at a time that it should have been brought out; namely, when the legislature was considering the bill by which it appropriated $60,000 of the $100,000 cost. The tunnel has nev er been completed. ★ F. C. Bolton, dean of the college, gave the committee figures show ing that a disproportionate num ber of cadet freshmen had left school last year, and then stated that in 75 cases hazing had been blamed, directly or indirectly. The investigating committee asked for names so that some of the departed fish might be asked to testify. Answering inquiries about the chemical science course and the Veterinary Medicine school, Dean Bolton stated that the chemistry course had been dropped from the approved list because the faculty was not doing enough research to satisfy the one-man inspecting party. No loss of quality in gen eral chemical instruction was indi cated, Bolton said, and there is no reason to believe that A. & M. is greatly different in this respect from many other schools. As for the Veterinary Medicine school, Bolton pointed out that it is still on the approved list. Asked about the faculty panel trial proposed for Clyde Cecil, on grounds of presiding at an unap proved meeting, (the senior class meeting which voted “no confi dence” in Ed Brandt and Jack Nel son) Bolton stated that the case had been dropped and there was no indication of the charge on Cecil’s records. Bolton presented to the commit tee photostatic copies of the schol astic records of all officers of the Veteran Students Association, showing that only Sam S. Wil liams had ever been up for discip linary action (hazing, in 1941). Holzmann’s Figures W. H. Holzmann, comptroller of the college, introduced figures showing that the cost to the tax payers of the Dean of Men’s of fice and commandant’s office com bined was about $35,000 a year, rather than the $100,000 allegedly alleged. That figure would be $23,000 more than for the com mandant alone. Jakkula-Penberthy Petition Read The petition recently circulated on the campus was read into the record from a copy certified to by Pathology Prof To Address Hort Club; Barbecue Planned Dr. A. A. Dunlay, chief of the Department of Pathology, will ad dress the Horticulture Society to night at 7 p.m. in the northeast corner room of the Animal. Hus bandry pavilion. Final plans for the annual bar becue will be made at the meeting. The barbecue will take place at the Hensel Park Saturday after noon, April 19, at 5 p.m. The park is located just north of the landscape nursery past the circle on the road to Bryan. Anyone planning to attend the barbecue who cannot be present at the meeting should contact the sec retary in the Horticulture office by Wednesday in order that an ac curate count can be made. A&M Model Aviation Club to Reorganize Aggie model airplane enthusi asts will re-organize the A. & M. College Model Aviation Club at 7 p.m. Wednesday, April 16, in Room 108, Mechanical Engineering Shops building. Older modelers will remember the pre-war club as primarily a group of free-flight model enthu siasts; however, it is expected that all phases of the hobby will be in corporated in the new organization. Regular “flying sessions” club con tests, and a number of technical! and scientific discussions are sched uled for the spring agenda. Rogers L. Barton, faculty ad visor, has indicated that the spon soring Industrial Education De partment will cooperate to develop this club into the most active or ganization of its type in this area. All model enthusiasts, regardless of whether they have models at the present time, are invited to be pres ent Wednesday evening. Need for Workers With Merit System The need for qualified workers in the state agencies served by the Merit System Council continues to exist. Through the medium of mer it examinations administered by the Merit System, returning vete rans, along with others who may be seeking employment, are offer ed an opportunity to secure em ployment in state service. Dr. A. A. Jakkula and W. L. Pen- berthy, who had certified, under notary seal, that 179 signatures were on the original petition held in Jakkula’s office, from among the 440 members of the faculty. About two dozen signatures were on another petition, from which one paragraph has been removed. Official Notices GRADUATE FELLOWSHIPS Graduate Fellowships, one each in Me chanical Engineering and Civil Engineer ing, will be available under a plan estab lished by the Humble Oil and Refining Company. These fellowships carry a stip end of $1,250 for the school year and need not be in fields related to petroleum al though it is hoped that the work of the candidate will be related to those fields. There is no obligations on the part of the student to accept employment nor is there an obligation on the part of the Humble Company to offer employment to the holder of the fellowship. The Humble Company has offered to assist in providing information which might be needed in preparation of the thesis. The candidate may work toward the Master of Science Degree or the Doc tor’s Degree. Applicants for mechanical engineering should contact Mr. C. W. Crawford and applicants for civil engineering should contact Dr. S. R. Wright at once.

Last month in this space the develop ment of nylon was traced from a funda mental research study on linear polymers to the first synthetic organic fibers, the superpolyamides. This installment deals with the complex manufacturing re search problems that followed. From the start there were obstacles to the production on a commercial scale of the ”66” polymer—so named because the adipic acid aiad hexamethylenedia- mine from which it is made have six carbon atoms each. Although adipic acid was being pro duced in Germany, it was necessary to develop a new process to meet conditions at Du Font’s Belle,W.Va., plant, where, because of the catalytic technique in volved, it was decided to make this intermediate. Hexamethylenediamine was only a laboratory curiosity, and a process for its commercial production had likewise to be worked out. Fortu nately it was found that the diamine could be made from adipic acid by new catalytic processes. The results of these investigations may be summarized as follows: > Carrying out experimental autoclave polymer izations of condensation polymers. J. H.

Nylon poly mer was an entirely new material with properties different from any previous synthetic product. It provided the first example of spinning fiber from a molten polymer (m.p.263°C) and required en tirely different techniques from rayon spinning. Information was acquired only by painstaking experimentation at each step. Manufacturing Process Outlined The process as finally developed for the manufacture of nylon and its fabrica tion into yarn may be briefly outlined as follows: Nylon salt is heated in an autoclave with addition of stabilizers to control More facts about Du Pont—Listen to “Cavalcade of America,” Mondays, 7 P. M. CST, on NBC molecular weight and viscosity. A lonj chain linear polymer is formed with molecular weight of 10,000 or higher. The melt is converted to solid chi; that are later re-melted and extrude through a spinneret to form filamen at a speed of 2,500 feet a minute. T1 filaments are then drawn out to aboi four times their original length in ord< to develop the desired textile qualitk characteristic of nylon. These operations sound simp] enough, but some of the problems ei countered were extraordinarily difficul For example, a specially designed gri for melting the polymer was necessai because of the poor thermal conducts ity of the polymer; pumps had to ope: ate at 285°C with only polymer as lubricant; special abrasion-resistar steels that did not soften or warp g 285°C were necessary; the spinning a < sembling required radically new eng neering developments to produce th necessary fiber qualities. All of these chemical, physical an mechanical engineering problems ha to be solved and dove-tailed into a un fied process before manufacture of nj Ion could be undertaken. In all, abou 230 technical men and eight manufac turing and staff departments share th credit for making nylon the importan part of American life it is today. Questions College Men ask about working with Du Pont WHAT ARE THE OPPORTUNITIES FOR ENGINEERS? Most openings at Dn Pont are for chem ical and mechanical engineers, but op portunities are also available for indus trial, civil, electrical, metallurgical, textile, petroleum and other engineers. Practically all types of engineering are required in the work of the ten manu facturing departments as well as in some of the staff departments.
