Abstract: 864,677. Liquid-liquid contacting apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 10, 1958 [Dec. 23, 1957], No. 39899/57. Class 81 (1). A liquid-liquid contactor shown schematically in Fig. 1 comprises a number of chambers connected in series by ducts all having a fall in the same direction from a high level in one chamber to a low level in the next. The end chamber upstream (in relation to the flow of the light phase liquid) has a light phase liquid inlet and a heavy phase liquid outlet, and the end chamber downstream has a light phase liquid outlet and a heavy phase liquid inlet and means for producing pulsations in the liquids whereby, in alternation, the light phase is pumped downstream and the heavy phase upstream through the ducts, the heavy phased being dispersed into the light phase in the chamber receiving it. Figs. 2 and 3 illustrate an embodiment of the invention in which the chambers are formed in a borosilicate glass tube 13 by partitions each comprising a pair of plates 14 and 15 having flanges 16 and sealing rings 17, the plates being mounted on a stringer 18 and positioned by spacers 19 and 20. The lower part of plates 14 on the downstream side of the partitions are perforated at 21 and the upper part of plates 15 are similarly perforated so that the space between each pair forms the duct between successive chambers. The light phase enters at 4 and leaves at 7 and the heavy phase enters at 8 and leaves at 5. Pulsating means 6, 23, 24 and 25 act to pump the light phase from chamber to chamber on one stroke, and to pump the heavy phase from chamber to chamber on the return stroke, the heavy phase being discharged through the upper perforations into the light phase. The level of the interfaces 10 between phases is controlled by arranging that the heavy phase supply rate is slightly less than the pumping rate of the pulsator. The interface 11 in the end chamber is separately regulated by valve 12. To prevent the trapping of air in the chambers when the apparatus is started, the upper part of the plates 14 and 15 are notched and the sealing rings are interrupted to leave small passages between the chambers. A number of straight units as in Fig. 2 may be arranged in parallel and connected in series by return bands at the ends of alternate pairs. In such an apparatus having sections in series having different functions, i.e. stripping and extraction. The intermediate feeds usually involved may be introduced at the return bends. Data of runs with a water-toluene system using acetone as solute are given.

Abstract: 1,072,418. Crimping. AMP Inc. Oct. 5, 1965 [Oct. 9, 1964], No. 41362/64. Heading B3Q. A fluid pressure operated crimping tool includes a pair of pivoted crimping jaws 1, 2 operatively connected by a toggle linkage 5 to the piston of a cylinder 4, supply of pressure fluid to the piston being initiated by a foot pedal and being stopped automatically after the jaws have closed a predetermined amount. Operation of the foot pedal (28) (Fig. 3, not shown) first connects points F and G so that fluid from a supply (23) flows along lines (27) and (25) to a supply control valve (21). This shifts a spool in the valve to connect points (B) to (C) and (A) to (D) so that fluid flows along line (22) to a control cylinder (13), forcing a piston (11) downwardly to thus move the spool (9) of a supply valve (8) downwardly. The cylinder (4) is then supplied with fluid and crimping takes place. When the piston of the cylinder (4) has risen a predetermined distance, an adjustable stop (20) contacts a pilot piston (17) of a shut-off valve (15) to shut off the supply to the cylinder (4). The valve (15) connects lines (14) and (16) so that the pressure in line (22) is directed through line (16) to a line (24), thereby shifting the spool of valve (21) to its original position in which points A and E are connected and line (16) vented. The piston (11) rises under its spring-loading to permit spool (9) to rise also, the cylinder (4) being vented and the crimping jaws opening. Operation of the pedal (28) will restart the cycle.
