Title: Improvements in or relating to the separation of alcohols
IPC: C07C29/74
Filed: 1934-04-25
Abstract: Unsaturated alcohols are separated from saturated alcohols containing at least the same number of carbon atoms, preferably not less than ten, by extraction with liquid sulphur dioxide at a temperature below 10 DEG  C. preferably --12 DEG  C.  In examples: (1) the mixed alcohols constituting the unsaponifiable portion of the oil of Ruvettus Pretiosus is extracted with sulphur dioxide in a Soxhlet apparatus, the condenser of which is open at the top for the introduction of solid carbon dioxide; (2) a mixture of oleyl and stearyl alcohols is extracted in the same manner; (3) a mixture of oleyl and stearyl alcohols obtained by hydrogenation of oleic acid is stirred with sulphur dioxide and the layers separated; more alcohol mixture and sulphur dioxide are added to the lower layer and the process repeated several times. Alternatively, the alcohol mixture may be treated with sulphur dioxide at a temperature high enough to cause the whole to dissolve under pressure after which the mixture is cooled and the saturated alcohols separate.  The process may be used for separating unsaturated alcohols such as citronellyl, linolyl, geranyl, linoleyl, eleostearyl, elaidyl, neryl, undecylenyl and heptadienyl alcohols from saturated alcohols such as decyl, cetyl, stearyl and palmityl alcohols and the separation of lower unsaturated alcohols such as allyl and crotyl alcohols from higher saturated alcohols.  Butyl and crotyl alcohols may also be separated in this manner.  Specification 366,025 is referred to.  The Specification as open to inspection under Sect. 91 includes the use of mixtures of sulphur dioxide with methanol, benzene, diethyl ether, ethyl acetate, liquid olefines such as amylene, and other organic solvents of sulphur dioxide, and an immiscible solvent such as chloroform, carbon tetrachloride, ethylene dichloride, or other halogenated hydrocarbon, dichlorodiethyl ether, dichlorodipropyl ether or other halogenated ether, cycloparaffins such as cyclohexane, and petroleum ether may be added to lower the melting point of the alcohol mixture to make it liquid at the temperature of liquid sulphur dioxide.  This subject-matter does not appear in the Specification as accepted.

Abstract: 718,923. Motor vehicles. DAIMLER-BENZ AKT.-GES. May 19, 1952 [May 18, 1951], No. 12659/52. Classes 79(2), 79(3) and 79(5) [Also in Group XXXII] In a motor road vehicle means for counteracting the effect of centrifugal force comprises power-driven apparatus, additional to the propulsion and steering mechanisms, adapted to produce an accelerated stream of a gaseous medium by whose reaction a centrifugal thrust is exerted on the vehicle at a point different from where the propulsion and steering forces are exerted. As shown in Fig. 1 the invention is applied to a vehicle comprising wheels 3 driven from the engine 4 through a change speed gear 5, a cardan shaft 6, a differential gear 7 and axles 8, and wheels 2 steered from a hand wheel 9 through a gear box 10, a drop arm 11 and linkage 12. When the wheels 2 are steerably deflected to positions 2<SP>1</SP>, the drop arm 11 makes a contact 19 thus completing a circuit to an electromagnet 26 which then engages through an arm 27 a clutch 17, the clutch connecting a gear box 15 driven either from the cardan shaft 6 or the differential gear box 7 to a blower 14. The blower causes a stream of air to flow in the direction Z 1 , the reaction thereof tending to counteract the effect of the centrifugal force F acting at the centre of gravity S and caused by the vehicle rounding the curve. A blower 13, an electromagnet 24, a clutch 16 and a contact 18 is arranged to produce a similar effect when the vehicle is steered in the opposite direction. In a modification. Fig 2 (not shown), a single blower is provided and may be driven either from the power transmission or an electric motor, the blades of the blower being adjustable from the driver's seat or independance on the steering. Instead of a blower with adjustable blades, a blower with a reversible drive may be provided. The transverse forces may be caused to act directly on the rear axle or to the rear thereof or else at or in front of the centre of gravity. The apparatus producing the centripetal force may alternatively be controlled by hand. or else the magnets 24, 26 may be replaced by centrifugal weights which are arranged to operate the device either directly or through the medium of a servo mechanism. Specification 713,277 is referred to.
