UNIVERSITY OF ILLINOIS

and Professor of Music on indefinite tenure, with a suitable adjustment in salary for the year as determined by the President of the University. Professor Branigan has served before as Acting Director of the School.

On motion of Mr. Livingston, these recommendations were approved.

RELEASE OF POTENTIALLY PATENTABLE DISCOVERIES (4) Professor C. S. Marvel of the Department of Chemistry reports some potentially patentable discoveries relating to the reaction between dithiols and unconjugated diolefins which result from research work done by former graduate students working under him and are described in the doctoral theses by P. H . Aldrich (1049) and P . D. Caesar (1950), as follows: (1) the preparation of polyalkylene sulfides from aliphatic dithiols and unconjugated diolefins in various types of emulsions in the presence of free radical initiators; (2) the high molecular weight orientable polyalkylene sulfides thus obtained; (3) the reaction of aromatic dithiols and unconjugated diolefins to give polyarylenealkylene sulfides which can also be achieved in emulsion in the presence of free radical initiators; (4) the use of an unreactive solvent such as benzene or methanol to give better emulsions when an aromatic dithiol is a reaction constituent; and (5) the polyarylene-alkylene sulfides as new products. Professor Marvel states that there is some domination of this field by a patent issued to D. D. Coffman but the improvements described above seem to be fundamental in getting usable polymers in this field. Professor Roger Adams, Head of the Department of Chemistry, has expressed doubts that it will be advisable for the University to take over the possible patentable material in this field in view of the dominating position of Coffman. On the basis of his report, the University Research Board recommends that the discoveries be released to the discoverers. I concur.

On motion of Mr. Livingston, these discoveries were released as recommended.

PATENT APPLICATION O N NEW COMPOSITIONS A N D STRUCTURES OF REFRACTORIES (5) Professor Ralph L. Cook of the Department of Ceramic Engineering reports the development of new compositions and structures of refractories which are particularly suitable for the lining of enamel smelters. T h i s is a result of research work financed by the Chicago Vitreous Enamel Product Company of Cicero, Illinois, the F e r r o Enamel Corporation of Cleveland, Ohio, and Pemco Corporation of Baltimore, Maryland, under a cooperative investigation entitled "the development and investigation of refractories for enamel smelter operation, with particular emphasis on those required for low temperature enamels" by the Engineering Experiment Station. T h e cooperating companies request that the University undertake the patenting of this development, the expenses to be paid by them. This conforms to University policy relating to such matters. T h e University Research Board recommends that a patent be secured in the name of the University. I concur.

On motion of Mr. Livingston, this application was authorized as recommended.

FEES FOR POSTGRADUATE COURSES (6) T h e Dean of the College of Dentistry and the Comptroller recommend, the Provost concurring therein, that the following schedule of fees be established for postgraduate courses in the College of Dentistry and that these fees be uniform for both residents and nonresidents of Illinois: Twelve-week refresher program (three months) .$150 00 One-week units., 25 00 Two-, three-, or four-week units 50 00
