6. Log-periodic series-type folded dipole array — Raj Mittra, Associate Professor of Electrical Engineering, and Marvin L. Wahl, Research Assistant in Electrical Engineering, inventors; developed with the use of funds from the United Air Force, Contract No, A F 33(657)-10474. It has been considered desirable to design a free-space model of a wideband antenna which has an impedance in the neighborhood of 300 ohms, such that it could be matched directly to a standard 300 ohm' line. A possible solution to this problem is the series loading of elements on the transmission line which, in effect, raises the input impedance of the antenna to a value larger than the characteristic impedance of the feed line itself. 7. Letter rack antenna — R a j Mittra, Associate Professor of Electrical Engineering, and Marvin L. Wahl, Research Assistant in Electrical Engineering, inventors; developed with the use of funds from the United States Air Force, Contract No. A F 33 (657)-10474. The antenna is a composite system consisting of a trough structure, which is coupled to another system made up of a series of loops, series loading an unbalanced transmission level. The heart of the present design is the coupling of the two systems, and the resulting antenna is considered to be a new device. Its important features are (a) flush mounting in aircraft bodies or flush with the ground, and (b) very broadband design (log-periodic). That the rights of the University in the following inventions be released to the sponsoring agencies, since the possibility of commercial value is remote: 8. Automatic area compensator of constant stress cycling —- C. E. Feltner, Research Associate in Theoretical and Applied Mechanics, and J. A. Jackobs, Engineering Assistant in Theoretical and Applied Mechanics, inventors; developed under research sponsored by the United States Air Force, Contract No. A F 33(6S7)-8177. This invention is highly specialized and will probably be rarely used except in situations such as were encountered in carrying out the contract research. 9. Electro-optical modulation of radiation pattern, photo-electric devices, and electro-optical method of light modulation — Gabor K. Ujhelyi, Research Assistant in the Digital Computer Laboratory, and Sergio T. Ribeiro, Research Associate in the Digital Computer Laboratory, inventors; developed under research sponsored by the United States Navy, Contract No. Nonr-1834(15). These inventions are in the area of lasers, in which the Government is very interested at the present time. The Navy is eager that applications be filed for patents; however, it is the opinion of the Director of the research and of the Committee that neither the University nor the Foundation should undertake the development of these devices at this time. That the rights of the University in the following inventions be released to the inventor or inventors, since the possibility of commercial value is remote and since the United States government is not involved: 10. Short method for blood glucose determination — Clarence A. Johnson, Sophie J. Presley, Jerome T. Paul, and Eugene J. Ranke, all from the Departments of Medicine and Biological Chemistry of the University at the Medical Center, inventors. The purpose of this study is to present a rapid, simple, and reliable colorimetric method for the determination of blood glucose, that may be used with or without the spectrophotometer; it represents a modification of the fluoran reaction. 11. Improved magnesium aluminate refractory compositions — Tracy A. Willmore, Research Associate Professor of Ceramic Engineering, and Alfred W. Allen, Professor of Ceramic Engineering, inventors; developed under research supported by the Amsted Research Laboratory. This invention relates to the improvement of the high temperature properties (transverse strength, in particular) of refractory materials fabricated from magnesium aluminate. The Head of the Department of Ceramic Engineering states that it appears that only the sponsor could receive the principal commercial benefits, if any arise. I concur.
