[Also in Division G1] Oscillations of a shaft 3 are damped by a film of fluid in the capillary gap 4 between the shaft and a continuous or discontinuous ring 1 of porous material (e.g. metal or nylon) fixed to a housing 2. The gap is required to be smaller at its centre than at its ends (e.g. stepped, as shown, or biconical). The ring 1 constitutes a fluid reservoir, supplying fluid (e.g. oil or silicone) to the damping film when the temperature increases, and absorbing it when temperature decreases, thus compensating for the change in viscosity with temperature and maintaining constant with temperature the viscous torque exerted on the shaft. Alternatively, the reservoir ring may be fixed to the shaft, and there may be two facing rings.

Weighing apparatus for determining the density of samples which must be remotely handled comprises a balance 5, so mounted above a cylindrical tank 8, which is rotatable about its axis on a non- rotatable supporting tray 17 and which contains a plurality of ducts (12) Fig. 3 (not shown), uniformly arranged and equally spaced from the axis, that baskets 13 for containing the samples and mounted within the ducts are arranged by intermittent rotation of the tank to be successively positioned below a hook 31 operatively attached to the balance and successively lifted in order to be weighed on to the hook 31 by a pneumatically operated jack 27 which is fixed to a platform 6 and which bears on pivoted levers 29 to which the sample baskets 13 are attached. During weighing operations, the balance 5 and the tank 8 are both positioned within a protective casing 9 provided with transparent walls and a hinged door 10 and the intermittent rotation of the tank is effected by a continuous chain (15) Fig.3 (not shown) passing round toothed wheels respectively attached to the tank 8 and a driving motor (16) mounted on and controlled by cam operated switches. The tank is movable, after weighing operations, to a position outside the protective casing 9 by arranging that the tray 17 is supported on rollers (18) within guide rails (19) Fig. 1 (not shown) and that the tray 17 is movable along the rails by a motor 23 which is mounted on the tray 17 and which drives a pinion engaging a fixed rack. Control of the motors (16) and 23 as well as a diaphragm pump which actuates the jack is effected at locations outside the casing 9. The density of the samples may be determined by effecting weighing operations of the samples with air in the tank and then repeating the weighing operations but with the samples immersed in water within the tank.
