Title: Process for the preparation of sulphuric acid solutions of nitrosyl sulphuric acid
IPC: C01B21/086
Filed: 1965-11-30
Abstract: A sulphuric acid solution of nitrosyl-sulphuric acid is produced by reacting preferably at -15 DEG  to + 70 DEG  C., in stoichiometric quantities, sulphurous anhydride with nitric acid, the reaction being conducted in a medium of sulphuric acid and in the presence of nitrosyl sulphuric acid and water as initiators, the initial quantity of water being such that the weight of sulphuric acid with respect to the sum of the weights of sulphuric acid and water comprises 70-97 per cent.  The initiator nitrosyl sulphuric acid may be formed in situ by the addition of NO2, a mixture of NO2 and NO or a mixture of NO and molecular oxygen to a mixture of sulphuric and nitric acids. Alternatively the initiator may be formed by the addition to a mixture of sulphuric and nitric acids, mineral salts or organic esters of nitrous acid or sulphurous anhydride in the presence of air.  In place of mixing sulphuric and nitric acids, a mixture containing the reaction components: sulphuric acid, nitric acid, water and nitrosyl sulphuric acid, may be obtained by the action of nitrogen peroxide on excess sulphuric acid.

Abstract: 1,146,438. Electric correspondence control systems. ULTRA ELECTRONICS Ltd. March 9, 1967 [Dec.9, 1965], No.52205/65. Heading G1N. An aircraft engine is controlled manually by means of a lever through a circuit wherein the engine parameters, e.g. speed and temperature, are monitored to determine which is nearer the value demanded by the control lever. This variable then determines the actual thrust of the engine for the given position of the lever. As shown Fig. 5, the control lever 15 is coupled to a potentiometer 16 in the speed monitoring circuit 18 and a potentiometer 17 in the temperature monitoring circuit 19. In the former, a frequency signal representing the engine speed is fed through a transformer 34 to transistors 24, 25 to charge a capacitor 23. Thus the potential at point 36, representing the actual speed, is compared with the potential at 35, representing desired speed, and the difference is fed to a circuit 37. Similarly the difference between actual and demand temperature produces a potential difference between points 38, 39 which is also fed to circuit 37. Whichever is smaller is fed out at 41 to the engine throttle control to vary the engine speed until the smaller signal is zero. The system thus allows continuous variation of speed by the control lever until the lowest maximum permissible value of the measured parameters is reached. The system may include a meter indicating the normalized engine output as a percentage of the maximum permissible output.
