Title: Improvements in and relating to winches
IPC: B66D1/26
Filed: 1960-04-04
Abstract: 944,427. Winches. A. BRUSSELLE. April 4, 1960 [April 4, 1959], No. 11844/60. Heading B8B. Each drum 3 of a twin drum ships' winding gear has a respective rope guide A, movement of which parallel to the drum axis is derived from gearing 37, 38 (Fig. 1), splined shaft 41 and co-operating worm 43 on the guide A. The worm 43 cuts via worm-wheel 45 to rotate a pinion 47 carried by the guide A and this engages with a rack 48 to provide the movement of the guide. To provide for reversal of movement when the guide reaches either end of its travel (since the drum accommodates a plurality of layers of the rope), the rack 48 is displaced from one side of the pinion 47 (Fig. 10), to the other side (Fig. 10B). This results from the interaction of the boss of the pinion 47 and a member 55 suitably profiled at 56 and rigid with the rack 48. The latter and member 55 at each end are mounted by linkage 58, 59 and on runways 61 to permit the displacement of the rack.

Patent GB-972749-A (GB)
Title: Improvements in or relating to the classification of particulate material
IPC: B03D1/001
Filed: 1963-03-26
Abstract: In a method of separating particles of material in a separating medium which has auxiliary particles distributed in it and has a density lower than the heaviest and higher than the lightest particles of the mixture being separated, friction is reduced in the medium by coating the auxiliary particles with an oily agent which is attached to the auxiliary particles by means of a heteropolaric agent, the molecule of which, on the one hand, has a reactive group which can react with the auxiliary particle to anchor the heteropolaric agent and thus also the oily agent to the auxiliary particle and, on the other hand, an oleophilic non-reactive group which adsorbs the oily agent.  The oily agent is preferably an aliphatic hydrocarbon such as combustible or lubricating oil and can be attached to auxiliary particles of oxidic iron ores (magnetite) by means of fatty acids or related acids, such as palmitic acid, tall fatty acid or salts of any one of these acids; if silica sand or rock is used as the material for the auxiliary particles then the oily agent can be attached to them by means of an alkyl amine such as octyl amine or dodecyl amine.  In an embodiment, the particles to be separated are supplied to a bed of treated auxiliary particles which are conveyed over a shaking table as water is flushed into the bed from below; air or another gas is blown into the bed from below for the purpose of controlling the density of the bed.  The invention is also applicable to the suspension procedure in which the material to be separated is supplied to a water suspension of the auxiliary particles.
