Patent GB-968334-A (GB)
Title: Process for the extraction of gallium and indium from anode slime
IPC: C22B58/00
Filed: 1961-03-08
Abstract: Gallium and indium are recovered by working up the anode slime which is formed in an electrolytic process employing aluminium or an aluminium alloy as anode, and an organometallic complex salt melt or solution as electrolyte. Methods of working up which may be used include physical methods of separation, e.g. evaporation, distillation, sublimation, flotation, centrifugal separation and methods which make use of differences in magnetic properties, for example fluidized bed methods of separation, and chemical methods of separation, e.g. selective oxidation, amalgamation, electrochemical methods and methods which make use of differences in the solubility of the various elements in different solvents. A preferred and novel method for separating the gallium, however, comprises drying the anode slime, reacting the dried slime with a halogen or hydrohalide to form a mixture of halides, separating the volatile halides including gallium halide from the non-volatile halides, treating the volatile halides with a non-aromatic hydrocarbon solvent to selectively dissolve the gallium halide, recovering the gallium halide from the resulting solution and working up the gallium halide into gallium, e.g. by electrolysis in an alkaline medium.  In the example the mixture of indium and aluminium chlorides remaining after the removal of gallium trichloride by the above method is separated by making use of the great difference in the rate of solution of the two halides in ethers.

Abstract: 385,577. Galvanic cells ; charging and discharging electrolytes. LAMPENUND METALLWARENFABRIKEN R. DITMAR GEB. BRI1NNER AKT.-GES., Erste Haidequerstrasse, Vienna..-(Assignees of Doman, A. ; Budapest.) March 21, 1931, No. 8773. Convention date, April 9, 1930. Void [Published under Sect. 91 of the Acts]. [Class 53.] In galvanic batteries having a storage chamber for electrolyte connected with the working chamber, the electrolyte is transferred to and fro as required by suitable alteration of the gas pressures acting on the liquid levels in the two chambers. It is preferred to compress the gas in the storage chamber, e.g. by means of an air-pump, a compressible ball or a container of compressed air, so that the electrolyte is pressed into the working chamber after use, the electrolyte is drawn back to the storage chamber by releasing the excess pressure therein. To prevent the compressed air from entering the working chamber, a liquid seal should be arranged between the two chambers. In the battery illustrated in Fig. 1, the working chamber 1 is divided by a partition 12 into two compartments which communicate through apertures 13. The positive electrodes 15 have helical grooves 15a. The rubber discs 17 form a tight seal when compressed by nuts 19. The supply pipe 5 has a non-return valve 5x; and a screw 7 in the branch 6 controls an escape valve 6b. The apertures 9, 10, 11 are adapted to be closed. ;The liquid seal is provided by 'having pipes 4 which' extend almost to the bottom of the storage chamber 2. In a modification, several independent working chambers are arranged above a common storage chamber, and the walls may form the positive electrodes. The height of the battery may be reduced by having the storage chamber on the same level as the working chamber, in which case only one electrode is insulated from the electrolyte. The tubes 4 may be closed by a disc attached to a threaded spindle, and may be sealed by electrolyte-filled depressions 26, Fig. 5. Pans 25 for the reception of sediment may be provided. The distributing chamber may be small compared with the working chamber, electrolyte being transferred from and to a distant container through a pipe connected to this distributing chamber.

Title: Improvements in or relating to lubricating and cooling systems
IPC: F01M5/00
Filed: 1933-03-25
Abstract: 421,561. Lubricating. LUBRICATION CONTROL CORPORATION, 105, South La Salle Street, Chicago, U.S.A. March 25, 1933, No. 9069. Convention date, March 26, 1932. [Class 12 (iii)] [See also Groups XIII and XIX] To obtain constant viscosity of a liquid in a circulating system, liquid from a pipe 18 is passed through a pair of paths 15, 16, under control of a valve 19. Liquid-attemperating means is provided in one of the paths. The liquid from the paths 15, 16, passes through a chamber 21, Fig. 4, wherein the liquid pressure is solely a function of the viscosity, and a connection 25 is led from the chamber 21 to the valve 19. As shown, for the lubricating system of an automobile engine, a pipe 15 is enclosed in a chamber 12 through which the engine cooling water flows, and a pipe 16 surrounds the chamber 12 so as to be air cooled. A spring 26 having an adjusting screw 27 opposes the effect of the pressure lubricant admitted to the other end of the valve through the pipe 25. On starting up the engine the lubricant is cold and a high pressure is soon generated in the pipe 25. The valve 19 moves to the right, Fig. 3, to pass the lubricant through the pipe 15 so that the cooling water in the chamber 12 tends to warm it. The temperature of the lubricant continues to rise until it is above that of the cooling water and then the latter acts to cool the lubricant. If the lubricant becomes too fluid the pressure in the pipe 25 falls and the valve 19 moves to the left so that the lubricant passes through the pipe 16 and is air cooled. The viscosity-responsive device comprises a chamber divided into three compartments by partitions 29, 30. Oil is admitted to the central chamber through a pipe 31 leading from the pipes 15, 16, and the pressure in this chamber is kept constant by a valve 34. A hole 29a in the partition 29 leads to the chamber 21, and a passage 33 interconnects the end chambers. A pipe 24 leads to a pressure gauge and to the pipe 25. The flow through the hole 29<a> is independent of the oil viscosity, whereas the flow through the passage 33 varies as the viscosity, so that the pressure developed in the chamber 21 is a function of the viscosity of the lubricant.
