946 BOARD OF TRUSTEES [February 21 CHANGE IN SABBATICAL LEAVE OF ABSENCE CASH, JACOB G., Professor of Dairy Science Extension, Urbana — sabbatical leave of absence changed from six months from January 1, 1968, on full pay, to three months from April 1, 1968, on full pay. A copy of the complete report is filed with the Secretary. ANNOUNCEMENTS FROM THE PRESIDENT OF THE BOARD FUTURE BOARD MEETINGS President Swain announced the following schedule for the next three meetings of the Board: annual meeting of the Board, March 20, 1968, Urbana (having been changed by vote of the Board from Tuesday, March 12) ; April 17, 1968, at Chicago Circle; May 15, 1968, in Urbana. RECESS On motion of Mr. Clement, the regular meeting was recessed and the President of the Board stated that following lunch, a meeting of the Committee on Buildings and Grounds had been called and that an executive session had been requested and was being ordered following the Committee meetings to consider recommendations relating to patentable discoveries, property acquisitions and pending litigation. LUNCHEON A film produced at the Medical Center Campus, "Educating the Dedicated," was shown to Trustees and other University personnel following the luncheon. EXECUTIVE SESSION When the Board reconvened, the same members of the Board, officers of the Board and officers of the University as recorded at the beginning of these minutes were present. The Board considered the following recommendations from the President of the University. RECOMMENDATIONS OF THE UNIVERSITY PATENT COMMITTEE (32) T h e University Patent Committee, with the concurrence of the Chairman of the University Research Board, submits the following reports and recommendations relating to patentable inventions by members of the staff. 1. Low pressure absolute manometer — Wilfred C. Schuemann, former Research Associate in the Coordinated Science Laboratory, inventor; developed under the sponsorship of the Joint Services Electronics Program and the National Aeronautics and Space Administration. The basic device consists of a metallic vane mounted on the end of an arm suspended at the center of a torsion fibre. The unknown pressure is on one side and a high vacuum on the other side of the vane. Molecules rebounding from one side of the vane give rise to a torque about the axis of the torsion fibre. A conducting grid is placed in front of the vane and a torque, opposing that caused by the molecules, can be produced by applying a voltage between the grid and the vane. A mirror is placed on the arm at the torsion fibre and optical techniques are used to determine a null position. T h e gas pressure on the back of the vane is made negligible by placing the vane in a wall between two vacuum systems. The first system contains the gas to be measured and the grid to produce the electrostatic force. The second system contains the suspension fibre mounting and a pump which has a pumping speed very much larger than the leakage conductance from system 1 to 2 through the gap around the vane. T h e Committee recommends that the rights of the University in this invention be assigned to the National Aeronautics and Space Administration, if that is the wish of that agency, and that the University not request a waiver from that agency for the use of the invention.
