Title: Pivoting doors for conveyor system tunnel - uses single direction motor and spring loaded tie rod to pivot doors
IPC: B65G17/30
Filed: 1973-06-29
Abstract: Two doors of a circular arc cross-section are pivoted open in opposite directions by a semi-directional motor and a tie rod pushing the lower door donwards whilst a second transverse tie-rod between the two doors pulls the upper door upwards. A further half turn of the driving wheel closes the doors again. The concave faces of the doors are towards the pivoting axes, so minimizing the necessary vertical height. The main tie-rod comprises two concentric shaft and a compression spring. In the event of anything jamming the doors when being closed, the compression of the spring prevents damage.

Abstract: 1465801 Dispersing gases in liquids; froth flotation apparatus OUTOKUMPU OY 3 June 1974 [5 June 1973] 24480/74 Heading B1C and B2X In a method of dispersing a gas in a liquid or slurry, (e.g. for froth flotation) by means of a rotor within a stator, the increase in hydrostatic pressure with increasing depth is compensated by a hydraulic pressure correspondingly changing with depth in order to keep the total liquid pressure substantially constant over the surface over which the gas is dispersed; this is done by arranging for the ring of liquid between the rotor and stator to increase in thickness with depth so that the centrifugal force acting on the liquid ring produces the compensating dynamic pressure. As shown in Fig. 1 gas is supplied through a hollow shaft and dispersed through passages 5 between which are "grooves" 8 through which the slurry circulates; the envelope of the rotor is cylindrical while the stator is shaped so that the clearance between them increases downwardly. In other embodiments the rotor may narrow downwardly while the inner envelope of the stator is cylindrical, or both may increase in diameter downwardly with increasing clearance (Figs. 4-7, not shown). In Fig. 1 the "grooves" 8 are closed at the bottom, but they may be open at both ends or shrouded at the top (see Figs. 2 and 3, not shown). The gas passages 5 in the rotor may be omitted (Fig. 8, not shown) and the gas introduced above the rotor through a downcover surrounding the rotor shaft (Fig. 12, not shown).

Title: Machine for sorting potatoes from stones and lumps of earth - utilises differences in impact characteristics
IPC: B07C5/34
Filed: 1975-02-12
Abstract: The potatoes and lumps of earth etc. are delivered by a conveyor to a set of rollers which feeds the objects one at a time to the impact diaphragm supported in the frame. An accelerometer is fitted to the underside of the diaphragm and sends a signal to the signal analyser which controls an electric motor which drives the selector mechanism. The selector mechanism raises or lowers the arm and so determines the pile into which the object falls. The signal generated by the accelerometer is determined by the force of the impact of the object on the diaphragm, this force being different for different types of objects.
