Patent GB-780406-A (GB)
Title: Improved method and means for continuously extracting an adsorbable solute from a clear solution or from a suspension of finely divided solids in a liquid
IPC: B01J47/10
Filed: 1956-01-03
Abstract: <PICT:0780406/III/1> <PICT:0780406/III/2> Liquid to be contacted is introduced at 13, Fig. 1, to a standpipe 11 and fed to the lower compartment 7 of a column 2 containing a bed 1 of granular adsorbent particles (e.g. ion-exchange resin) retained between screens 3 and 4. The liquid passes up through the bed at such a rate that the bed is lifted against the upper screen 3; the pulsating action of a diaphragm 8 driven by a rotating cam 9 maintains the bed in a semi-fluidized condition. Fresh adsorbent is drawn in from one or more hoppers 5 at every downstroke, and its egress is substantially prevented by the reduction in the fluidity of the bed during the ensuing upstroke. Adsorbent is entrained from the base of the bed by liquid flowing through a pipe 14, its flow rate being controlled by adjusting the height of the discharge, and the mixture is delivered to a de-watering device 15 (e.g. a filter), whence filtrate is pumped back (16) to the standpipe 11 and adsorbent is delivered for ensuing processing.  Treated liquid leaves the column 2 at 6.  In a modification, not shown, the upper screen is dispensed with, and only flow rates below the fluidizing velocity are used.  Also, the lower screen is coarser than the particles of the bed and is separated from the bed by a layer of sand.  The liquid to be treated is pumped into the compartment 7, to which also the filtrate from 15 is separately returned.  The diaphragm is driven in symmetrical strokes by an eccentric.  Fig. 4 is an embodiment designed for pulsations of low frequency and large amplitude. Liquid to be treated is pumped (28) to a head tank 24 connected, past a float valve 32, alternately to vacuum at 30 and air at 31 by a valve 29.  Surges of liquid thus produced in tank 24 bring about corresponding surges in the column 2. A bed of sand 27 on a further perforated plate 26 acts as a flow distributor.  Surges in the adsorbent outlet pipe 47 are reduced by a throttle valve 33 and by a surge tank 34.  The upper screen 3 may be coarser than the adsorbent particles and separated from them by a lower-density bed of coarse particles.  The pulsations may be produced by either a diaphragm or a piston operating in a chamber communicating with a gap in the liquid inlet pipe.  In an example, uranium is removed from a leach pulp containing uranim oxide by an ion-exchange resin and is thereafter eluted; the resin slurry is raised to the dewatering device by air-lift.

Filed: 1962-01-08
Abstract: 964,041. Jointing by stamping. BURNDY CORPORATION. Jan. 8, 1962 [Jan. 10, 1961], No. 625/62. Heading B3Q. [Also in Division B5] A system for compressing an article, such as a terminal on to an energized electrical conductor, comprises an hydraulic power source 401 connected by two independent circuits which are isolated from each other and connected in series to an hydraulically-operated compression tool 101. The tool has jaws 103, 105 and is mounted on one end of a rigid tube 203 of fibre glass, the other end of which is received in a separator 210 having a disc 251 slidable in a housing 205, 207, the disc at one side being exposed to a fluid, such as transformer oil, in the tube 203 and at the other side being exposed to the fluid, such as hydraulic oil, in a flexible tube 107 connected to a pump 401. The disc 215 is formed as a piston having seals 231, 233 and is urged by a spring 221 towards the flexible tube. An electrical control circuit, which can be set to semi-automatic or manual operation, together with a valve arrangement 501 control the system so that on a first operation of a switch controlled by an air bulb 109, the pump is started and fluid at a pressure determined by a low-pressure relief valve 425 is passed from a connection 411 leading from the pump to a connection 415 joined to the flexible tube so that the jaws 103, 105 grip the terminal. Upon a second operation of the switch, a solenoid 520 is operated to retract a rod 419 against a spring 417 so that a ball valve 421 can close and prevent flow to the low-pressure relief valve, the pressure in the tubes then being limited by a maximum pressure relief valve 429. The maximum pressure is sufficient to effect crimping of the terminal on to the conductor and when it is reached, the valve 429 lifts to allow a flow of oil through a passage 435 to operate a switch and stop the pump, the jaws then retracting from the terminal. In an alternative embodiment, a second fibre-glass tube surrounds the first 203 and the space between the tubes is filled with loose fibre glass. Specification 964,042 is referred to.
