Title: Method of electrolytic extraction of metals
IPC: C25C1/00
Filed: 1964-08-04
Abstract: Metals of which the sulphides are soluble in aqueous alkali metal sulphide solutions are extracted electrolytically from aqueous alkali metal sulphide solutions of sulphides of said metals using an anode comprising an alkali metal or alkaline earth metal amalgam.  The metals extracted are typically As, Sb, Sn, Au, Hg, Pt, & W.  The cell employed may be divided into two compartments by a porous diaphragm of ceramic or synthetic material and the anode compartment contains a solution of an alkali metal or alkaline earth metal sulphide, while the cathode compartment contains the sulphide solution of the metal to be extracted, e.g. sodium thioantimonite or thiostannate or Hg S in sodium or potassium sulphide.  If the anolyte is sodium sulphide sodium amalgam is used as anode, while potassium amalgam is used with potassium sulphide.  The level of the anolyte is maintained above that of the catholyte to cause a flow of alkali metal sulphide into the cathode compartment.  The process, which is self exciting when an external electrical connection is made between the electrodes, may be assisted by an externally applied voltage. The cathode may be Pt and the amalgam anode may include a vertical iron disc dipping into an amalgam pool and rotatable on a horizontal axis above the pool.

Title: Improvements relating to ion-exchange processes and plants
IPC: B01J49/00
Filed: 1946-10-29
Abstract: 624,884. Purifying liquids. PERMUTIT CO., Ltd., and SARD, B. A. Oct. 29, 1946, No. 32101. [Class 46] [Also in Group XXXVI] In a cyclic cation-exchange process, effluent is passed during the working stage from the cation exchanger to an auxiliary cation exchanger, the electrical conductivities of the effluents from the main cation exchanger and the auxiliary cation exchanger are compared, and the regeneration stage initiated when the conductivities differ by a predetermined amount. At the start of the working stage in the plant shown, liquid to be treated is supplied by a pipe-line 1 through valve A and connection 4 to a cation-exchanger 3, passing downwards through the material, and out by a connection 5 to the service main through a valve E and a conductivity cell 10, valve B being shut. A portion of the effluent, however., passes through a valve C, an auxiliary cation-exchanger 9, and a conductivity cell 11 to waste. The cells 10 and 11 form opposing arms of a Wheatstone network 12, the difference, if any, between the conductivities being shown on an indicator 13. Whilst the contents of the main exchanger 3 are in working condition, the auxiliary exchanger 9 which is maintained at full capacity will not perform any further ion exchange, and hence will not bring about any change in the conductivity of the main effluents. The conductivities in the cells 10 and 11 will thus be the same and the bridge will be in balance. As the contents of the main exchange become exhausted, however, the conductivity in the cell 10 will change, and the indicator 13 will show when regeneration should be initiated. After backwashing of the main exchanger 3, valves G and D are opened, the remainder being shut, so that acid for the regeneration step may pass from a container 6 through a diffuser 8 and the exchanger 3 to waste via the valve D. The apparatus is then washed with liquid from the pipe 1, which passes through valve A and connection 4 into the main exchanger, and through connection 5 and valve D to waste, the remaining valves being shut. The material in the auxiliary cation-exchanger may be regenerated by wash water which has passed through the main exchanger after regeneration thereof and contains excess acid. The indicator 13 is put out of action from the end of one working stage until a few minutes after the start of the next. Lack of balance in the bridge circuit may be used to operate a relay for setting the valves to initiate the regeneration step, other relays being. operated by time switches for the remaining operations.

Title: An improved process for the recovery of pectic products from vegetable matter
Inventor: WALSH CONRAD LAWRENCE
IPC: C08B37/06
Filed: 1947-12-05
Abstract: Pectic products are obtained from vegetable matter by treating with an alkali metal or ammonium salt having a basic or neutral reaction, and then precipitating a pectic acid gel by the addition of sufficient acid to maintain a pH of 4-2.5.  The vegetable matter, e.g. roots, stems, leaves, flowers, fruits, or seeds, may be first treated for the removal of fibre, wax, chlorophyll, alkaloids, hydroxy acids, glucosides, sugar, saponins, or other constituents, and is then extracted with an aqueous solution of the alkali metal or ammonium salt such as the carbonate, bicarbonate, sulphite, phosphate, or oxalate.  After filtration or screening to remove vegetable matter, the solution is treated with the acid, preferably fairly concentrated hydrochloric or sulphuric acid, the liquid is filtered through a corrosion-resisting metal gauze, and is pressed, after washing, if desired, to remove water. Bleaching may be effected by chlorine, hypochlorites, sulphur dioxide, or sulphites before pressing.  The gel may then be dried or reacted with an oxide, hydroxide, bicarbonate, or carbonate of an alkali metal, ammonium, or alkaline earth metal, the product in each case being comminuted by ball milling or otherwise. Specification 582,147 is referred to.
