PATENTABLE D I S C O V E R I E S The University Patent Committee submits, with the concurrence of the Chairman of the University Research Board, the following recommendations relating to potentially patentable discoveries. 1. Use of Biuret as a nonprotein source of nitrogen ration in feed for ruminant livestock — Upson S. Garrigus, Associate Professor of Animal Science, E. Everett Hatfield, Instructor in Animal Science, and William Gaither, Assistant in Animal Science, inventors. Biuret is a synthetic product, and its use as a component of livestock ration was developed by the above named University staff members while working on a research project financed by the Grace Chemical Company. The contract covering this investigation includes the standard University provision that if the sponsor assumes all costs of applying for a patent on any discovery resulting from an investigation, the University will grant him a free nonexclusive license. The Grace Chemical Company has exercised its option to pay all costs of securing such a patent and to assign all rights therein to the University. In the patent application, Dr. David M. Clark of the Company's staff has been named as a coinventor, because the original idea regarding the use of Biuret as a ration was suggested by him and he collaborated with the University in the research. The Company will carry on the necessary proceedings, including patent search, filing and prosecuting the patent application. This is being reported as a matter of record and no action is required. 2. Vacuum quenching of porcelain enamel and ceramic coating frits — Dwight G. Bennett, Research Professor of Ceramic Engineering, and W. J. Plankenhorn, formerly Research Associate Professor of Ceramic Engineering, inventors. This is an apparatus and method of heating well-mixed porcelain enamel or ceramic coating frit ingredients, fusing them into a liquid state and quenching them in a vacuum chamber wherein the molten frit is expanded and cooled, instead of quenching in water. The invention was referred to the University of Illinois Foundation (as authorized by the Board of Trustees on April 21, 1954, minutes pages 1304-1305) for investigation and report. As a result of this investigation, the Foundation has filed an application for a patent. Approval of this application and release of the University's interest in the invention to the University of Illinois Foundation for the development of commercial possibilities which any patent issued may have is recommended. 3. Control Systems Laboratory discoveries. The following discoveries and inventions by members of the Control Systems Laboratory staff are reported: An isosceles triangle generator — Paul E. Harris, Research Associate, inventor. Method of employing the doppler B scope as an airborne moving target indicator — Ira Weissman, Research Associate, B. D. Kirkwood, Research Associate, and E. M. Lyman, Professor, inventors. An electronic circuit for developing a voltage function proportional to radial displacement of the beam of a cathode ray tube, storage tube, and/or similar devices — Ira Weissman and E. M. Lyman, inventors. Doppler simulator — Willis O. Unruh, Research Associate, and E. M. Lyman, inventors. Storage tube spectrum analyzer — George S. Newell, Assistant Professor, Willis O. Unruh, and Ira Weissman, inventors. A diode switching circuit for applying the necessary potentials to the back plate of a barrier grid storage tube — Paul E. Harris, inventor. Gated triangle generator — John K. Robe, Research Associate, and Paul E. Harris, inventors. Gated free running automatic shut-off flip-flop circuit — John K. Robe, inventor. A method of producing a range versus velocity display for M T I — John K. Robe, inventor. A stable drive circuit for the constant incremental gain limiter amplifier — B. D. Kirkwood, Research Associate, inventor. Vacuum tube circuit for connection and disconnection of sensitive amplifier from collector-repeller electrode of storage tube — Willis O. Unruh, inventor. A method of operation to reduce erasure time in beam current transmission modulated storage tubes — Willis O. Unruh, inventor.
