Abstract: 756,334. Fractionation of ethylene oxide condensation products. BRITISH PETROLEUM CO., Ltd., [formerly ANGLO-IRANIAN OIL CO., Ltd.], DESTY, D. H., and HARBOURN, C. L. A. Dec. 3, 1953 [Dec. 31, 1952], No. 33051/52. Class 2 (3). A non-ionic surface active agent comprising a mixture of non-ionic surface active compounds containing, in the molecule, a chain of ethylene oxide groups, is separated into fractions differing in surface active characteristics by adding to a solution of the surface active agent in an organic solvent, a precipitating agent in which the surface active agent is only partially soluble, the precipitating agent being a liquid miscible with the solvent, whereby part of the surface active agent is thrown out of solution to form a precipitated fraction which is recovered. The precipitated fraction contains an increased proportion of compounds having relatively long ethylene oxide chains compared with the compounds remaining in solution. A plurality of precipitated fractions may be obtained by progressive additions of the precipitating liquid or by progressively lowering the temperature. The surface active agents may be prepared by reaction of ethylene oxide with a suitable organic compound containing an -OH or -SH group, for example a fatty acid, resin acid, alcohol, alkylated phenol or mercaptan. The mixture so obtained may be fractionated as described above, and after removal of the precipitated fractions, the solution may be distilled to remove solvent and precipitating agent to give the residue comprising compounds with short ethylene oxide chains which may be recycled to the reaction mixture comprising ethylene oxide and the organic compound. Specified solvents are ethanol, acetone, benzene, toluene, cyclopentane, cyclohexane, carbon tetrachloride and chloroform, cyclohexane being preferred. Specified precipitating agents are iso- or normalpentane or hexane or heptane and iso-octane, iso-hexane being preferred. In examples, a liquid non-ionic surface active agent of formula wherein R is an alkyl group of, on average, 8 carbon atoms, A is a benzene ring and n is approximately 12, is dissolved in cyclohexane and two-thirds thereof is precipitated in two fractions by the progressive addition of isooctane, the remainder being recovered after distillation of the solution. The fractions are reacted with urea as described in Specification 697,315 and the solid products obtained compared with the corresponding product from the unfractionated material.

Abstract: 856,139. Automatic control systems for aircraft. SMITH & SONS (ENGLAND) Ltd., S. Nov. 5, 1957 [Nov. 5, 1956], No. 33702/56. Class 38 (4). In an aircraft automatic piloting system the elevators are deflected at a rate corresponding to the actual rate of pitch about a horizontal axis as computed from the rates of turn about athwartship and vertical axes in the aircraft and the actual roll angle. Elevator control.-As shown, electrical signals from gyros 1 and 2 rigidly mounted on an aircraft and respectively responsive to rates of roll about the athwartship and vertical aircraft axes are applied to the stator of a resolver 3 the rotor of which is positioned in accordance with actual roll angle by a repeater motor 4 controlled by signals from a gyro vertical 5. The output signal from the rotor of resolver 3, which is thus proportional to the rate of pitch about a truly horizontal axis, is applied to a servomotor system 13 which, by virtue of rate feedback, corrects pitch by adjusting the elevators (not shown) at a rate corresponding to the rate of pitch. Signals from any one of three devices 8, 9, 10 respectively responsive to altitude, air speed or radio glide path deviations may also be selected to control servomotor 13 and thus maintain a desired altitude or speed. A computer 7 adds differential and integral components to the altitude or speed control. Aileron control.-To maintain a desired course, signals from a magnetic or radio compass 16 are combined with signals dependent on roll angle, rate of turn, and rate of roll to control a rate servomotor system 21 adjusting the ailerons. Signal limiters 33, 36, signal smoother 34, and a device 35 to set the relative magnitude of the control components, are provided. Rudder control.-Course deviation signals combined with roll angle signals and rate of turn signals are differentiated by a computer 24 and serve to control, in conjunction with signals from a side-slip detector 26, a rate servomotor system 28 adjusting the rudder.
