all flashes of equal intensity. T h e features of this arrangement are low stray inductance with high light gathering efficiency and operation in an atmosphere of nitrogen. In concurrence with various members of the Department of Physics, the Committee recommends that the rights in this invention be released to the sponsoring agency, the United States Air Force. 2. Contour-tracing pattern recognizer — Paul Weston, Research Assistant in Electrical Engineering, inventor. This device consists of an oscilloscope, a photomultiplier which receives light from the oscilloscope face and a special feedback circuit connecting the photomultiplier to the oscilloscope. It is impossible to exhaustively enumerate the methods which are applicable to this process. In concurrence with the head of the department and the inventor, the Committee recommends that the rights in this invention be released to the sponsoring agency, the United States Navy. 3. Agitator-incubator for aseptic culturing of virus-infected cells and tissue in liquid media — H . H . Thornberry, Professor of Plant Pathology, inventor. The apparatus was constructed to provide the growth of isolated plant tissue cultures under aseptic conditions in a chemically defined liquid medium with controlled temperature and aeration by agitation. In concurrence with the head of the department, the Committee recommends that the rights in the invention be released to the inventor. 4. Automatic recording light-scattering instrument — Hiroshi Mizukami, Graduate Student in Biophysics, inventor. The light-scattering instruments are designed so as to measure the ratio of the intensity of incident light Io and that of scattered light from a sample cell I. In general, the angular dependence of scattered light is measured with rotating either a photomultiplier or a minor system around the cell manually. After study and report by the University of Illinois Foundation, the Committee recommends release of the rights in this invention to the sponsoring agency, the United States Public Health Service. 5. Iron core electromagnet with windings of miobium — G. B. Yntema, Research Associate in Physics (1954), inventor. There are two potentially novel features in this design — the use of superconducting windings and the use of iron to augment the field possible with superconducting windings. After study and report by the University of Illinois Foundation, the Committee recommends the release of the rights of the University in this invention to the inventor. 6. Methods for generating hypersonic waves in liquids — Floyd Dunn, Associate Professor of Electrical Engineering, inventor. T h e novel features of the invention lie in the fact that the quarter wave matching sections of two methods considered enable a sufficiently high electric field gradient to be developed over the thickness of the piezoelectric plate such that the plate vibrates and thereby produces sound waves in the contiguous liquid. After study and report by the University of Illinois Foundation, the Committee recommends release of the rights of the University to the sponsoring agency, the United States Navy. 7. Non-contacting device for accurately locating the spin axis direction of a rotating object — H o w a r d W. Knoebel, Research Associate Professor in the Coordinated Science Laboratory, and A. T. Nordsieck, Research Professor in the Coordinated Science Laboratory, inventors. T h e device employs two diametrically opposite photoelectric, magnetic, or electrostatic transducers which scan the surface of the rotating object and produce electrical signals in accordance with random surface texture or pattern material applied to the surface of the rotating object. After study and report by the University of Illinois Foundation, the Committee recommends that the rights of the University be released to the sponsoring agency, the United States Army Signal Corps. Group B. In the judgment of the Committee, the inventions in this group are potentially patentable and may have some value. The Committee therefor recommends that the University's rights be released to the University of Illinois Foundation for further study, development, and possible patentable application. 1. Transistorized digital-to-analog converter — William J. Kopek, Research Assistant in the Coordinated Science Laboratory, and Jack Stifle, Research Assistant in the Coordinated Science Laboratory, inventors. This device utilizes switching techniques whereby constant voltage or constant current generators are switched into or out of a coupling network, and the sum of the voltages or currents produced by these generators at the output is the analog representation of the input digital level.
