be transferred to the University of Illinois Foundation, subject to the rights of the sponsoring agency, for further development and possible patent application. 5. Use of aldehydes to treat protein of ruminant diets — E. E. Hatfield, P r o fessor of Animal Science; A. P. Peter, Research Assistant in Animal Science; and U. S. Garrigus, Professor of Animal Science, Urbana, inventors; developed under the sponsorship of the Moorman Manufacturing Company. Research has provided evidence that patterns and levels of the essential amino acids infused postruminal affect the performance of experimental ruminants. T h e aldehydes appeared effective in inhibiting ammonia production from soybean meal substrates. The Committee recommends that the rights of the University in this invention be released to the inventors. 6. Pond water sampler — J. Kent Mitchell, Assistant Professor of Agricultural Engineering; and Elbert C. Dickey, Research Assistant in Agricultural Engineering, Urbana, inventors. This device allows one person to obtain a water sample from within a small pond or lagoon, at a desired depth, without the use of a boat by assembling the device on the shore, floating it to the position desired on the pond surface, lowering the sampler to the desired depth, obtaining the sample, and then retrieving the sample by following the previous steps in reverse order. T h e Committee recommends that the rights of the University in this invention be released to the inventors. 7. Process for converting swine excreta to a swine feed source — B . G. H a r mon, Associate Professor of Animal Nutrition in Animal Science and D. L. Day, Associate Professor of Agricultural Engineering, Urbana, inventors. A process has been developed by which the quantity of animal waste for disposal can be reduced while a valuable feed source is obtained. Swine manure is collected and held in liquid form in an aerobically maintained pit. As in the production of activated sludge in municipal plants the excreta is biologically modified to an even higher concentration of microbial life (yeast and bacteria). The microbiota serves as a form of monocellular protein. T h e biological alteration is not unlike the building of yeast (monocellular protein) from hydrocarbon wastes of the petroleum industry. T h e Committee recommends that the rights of the University in this invention be released to the inventors. 8. Spark erosion cutting of germanium — H . K. Birnbaum, Professor of Physical Metallurgy; W . L. Haworth, Research Associate in Metallurgy; and R. P . Walson, Research Assistant in Metallurgy and Mining Engineering, Urbana, inventors; developed under the sponsorship of the United States Office of Naval Research. In the course of studies of dislocation behavior in germanium single crystals, it has been necessary to fabricate specimens having somewhat unusual shapes. The normal cutting techniques, which involve the use of a diamond wheel, abrasive wire saw, or an ultrasonic abrasive cutter, were found either to be unsuitable or to require a large amount of hand lapping subsequent to cutting to eliminate surface damage. It was found that the crystals could be easily and rapidly cut using a spark erosion machine and that under the proper conditions a negligible amount of surface damage resulted. The Committee recommends that the rights of the University in this invention be assigned to the sponsoring agency. 9. Autotutorial carrel for library stacks — Deam H . Ferris, Associate P r o fessor of Veterinary Pathology and Hygiene, Urbana, inventor; developed under the sponsorship of the United States Public Health Service. This particular carrel was designed to be used in the library stacks. It is designed to hold a tape recorder, cartridge type motion picture projector and desk type slide projector. It provides desk space for note-taking and display space for charts, posters and other visuals. The carrel may be closed and locked. T h e Committee recommends that the University not file a patent application because the invention is probably not patentable and that the rights of the University in this invention be assigned to the sponsoring agency. 10. Four-channel compact counterflow heat exchanger — Wendell Potter, Jr., formerly Research Assistant in Physics, Urbana, inventor; developed under the sponsorship of Advanced Research Projects Agency. This invention is a very efficient, compact counterflow heat exchanger in which one gas stream exchanges heat with three other gas streams all flowing in the opposite direction. It is made
