IPC: G01K5/70
Filed: 1956-04-27
Abstract: 838,295. Electric measuring systems. RHEOSTATIC CO. Ltd. March 27, 1957 [April 27, 1956], No. 13018/56. Class 40 (1). [Also in Groups XIII and XXXV] A device sensitive to rate of change of temperature comprises two thermally-sensitive elements having similar coefficients of expansion, coupled together to operate a variable resistance in a temperature control system. The tube 2 acts as a heat shield for the rod 1 during the application of heat, so that the rod expands less than the tube and the resulting movement of arm 5 operates the slider 7 on resistance 8. At a steady temperature both elements expand or contract the same amount and the resistance has a value fixed by adjusting knob 9. The change in value of resistance 8 therefore corresponds only with a rate of change of temperature. In the circuit of Fig. 3, resistance 36 is rate-dependent and is arranged in circuit with temperature-varied resistance 32 and feed-back controlled resistance 34 to vary the current through the coils 26, 27 of a balanced relay 28 operating in either direction a servomotor 35. In an alternative embodiment of the device (Fig. 2, not shown) two similar liquidfilled tubes 10, 11 operate through expandable capsules 12, 13 on arms 14, 15 to vary the position of slider 20 on resistance 18. Tube 11 is heat-lagged, 21, and responds more slowly to change of temperature than does tube 10. In Figs. 4 and 5 (not shown), are alternative control circuits for use with the device.

Title: Improvements in or relating to liquid-liquid extraction
Inventor: WATT PETER RIDGWAY
IPC: B01D11/04
Filed: 1963-04-03
Abstract: 998,646. Centrifugal liquid-liquid extraction. VITAMINS Ltd. July 2, 1964 [April 3, 1963], No. 13243/63. Heading B1F. In centrifugal liquid-liquid extraction, the liquids to be contacted are centrifugally distributed in the form of separate layers of annular form, agitated by insertion of an agitator into said layers and allowed to re-form into said layers by removal of the agitator, one of said layers being then separately collected. As shown in the Figures, a plurality of cells separated by annular plates 11 attached to a rotatable drum 10 each comprise one such extraction zone, the drum being rotated by means of a drive connected to one of supporting rollers 12. A tube 14, parallel but not coaxial with drum 10, supports an agitator 17 withdrawal tube 19 and drain tube 18 for each of said cells and is rotated by means of a drive to supporting shaft 35 in the reverse direction to the drum. As the tube 19 rotates, the agitators 17 first enter the layers of liquid formed by rotation of the drum whereby strong ,agitation takes place: further rotation of the tube lifts the agitators clear of the liquids which thus re-form into layers, after which the withdrawal tubes 19 reach the position shown in Fig. 7 and begin to remove the inner layers into separate cells formed in tube 14 by means of discs corresponding in position to the annular plates 11. Continued rotation of the inner tube brings the outlet pipes 18 into a position to discharge the removed liquid, and said pipes are so shaped as to convey said liquid into the next adjacent zone of the outer drum. The lower phase is filled into the apparatus before commencing to run the machine: the upper phase is introduced by means of a scoop 24 which enters a reservoir shown in broken outline at 38. Liquid is removed through line 25. Further modifications show (a) the provision of a second series of withdrawal pipes to remove the outer layers after removal of the inner layers, the arrangement being such that an inner layer from one cell and an outer layer from an adjacent cell are collected into a single cell in the central tube, (b) a withdrawal pipe having chamfered end surfaces to obviate disruption of the layers, and (c) a different arrangement of agitator and tubes on tube 14 whereby the latter may be rotated in the reverse direction. In a further embodiment each cell in tube 14 has a median partition forming two halves into which the inner and outer layers from adjacent cells in the drum are withdrawn, for subsequent discharge into a common cell in said drum. It is also stated that by the use of two withdrawal tubes both layers may be transferred in opposite directions, the liquid to be treated being introduced at the centre of the apparatus whilst effluents of constant composition are withdrawn at the ends.

Abstract: 542,333. Harvesting root crops; conveyers. BOULY, H. G. (Aktiebolaget Overums Bruk). Aug. 23, 1940, No. 13412. [Class 6 (iii)] [Also in Group XXX] A machine for harvesting potatoes or other root crops has a digging share, an endless conveyer arranged longitudinally on the machine for removing the haulms and a transverse endless conveyer for removing the roots. As shown the haulm conveyer is placed behind the share 6 and comprises two endless chains 17, 18 with links each formed of two substantially rectangular plates 23, 24, Fig. 6, rigidly connected by bolts 25, the arrangement being such that where the chains run parallel and close to one another, a plate of one chain projects between plates of the other chain and the haulms are bent zig-zag and gripped by the plates. The haulms are thus carried back and deposited on the ground. The chains may be replaced by rubber belts having projecting ribs. The root conveyer 7 is formed of two endless chains connected by transverse rods and is arranged across the machine passing below and behind the share 6 so as to receive roots and soil therefrom. Some of the transverse rods are provided with upstanding ribs or pins 26a which aid in stripping the roots from the haulms. The ribs or pins may be slightly inclined in the rearward direction and may be higher at one edge of the conveyer than at the other. The roots are delivered by the conveyer 7 on to a bar screen 13 from which they are passed to a scoop elevator 14 for bagging. The conveyers and elevators are driven by gearing from the axle of the rear wheels 3 of the machine. Fig. 9 shows an elternative construction of root conveyer, which is formed of transverse rods 29 having ends bent to form chain links. Some of the bars have pins 30 thereon to serve as stripping members.
