Title: Improvements in or relating to the extraction of germanium from flue dust
IPC: C22B41/00
Filed: 1954-08-16
Abstract: Germanium is extracted as its tetrachloride from flue dust by treating it with one to two times the theoretical quantity of hydrofluoric acid to convert all the silica present to silicon tetrafluoride, with or without the addition of sulphuric acid or an acid sulphate, heating the mixture to dryness to drive off the resulting silicon tetrafluoride and thereafter treating the residue with hydrochloric acid and distilling off the germanium tetrachloride, preferably in a stream of chlorine.  The hydrofluoric acid may be added to the flue dust and the mixture stirred until the reaction almost ceases before the addition of sulphuric acid or an acid sulphate.  If desired the hydrofluoric acid may be formed in situ by the addition to the flue dust of a fluoride such as sodium fluoride, together with sulphuric acid and if excess of the latter remains after the initial treatment of the flue dust the hydrochloric acid for the subsequent treatment may be formed in stiu by adding a metallic chloride such as sodium chloride.  As a modification, the acid treated flue dust is heated to dryness as before and the residue is leached with water, the germanium taken into solution is precipitated and separated for example by treatment with sodium carbonate, and the germanium containing precipitate is treated with hydrochloric acid and the germanium tetrachloride distilled.  The silicon tetrafluoride evolved in the first stage of the process may be treated with aqueous carbonate of ammonia and the hydrated silica precipitated to leave a solution of ammonium fluoride which may be treated with a soluble sodium salt to precipitate sodium fluoride. The residue remaining after distillation of the germanium tetrachloride contains gallium trichloride which may be extracted by known means.

Abstract: 1432173 Tyre inspection apparatus PICKER CORP 18 May 1973 [19 May 1972] 23817/73 Heading B7C [Also in Divisions H3-H5] A tyre inspection apparatus comprises a source 17, e.g. an X-ray tube, producing a beam of radiation which in operation sweeps the tyre from bead to bead, a receiving unit 16 moveable, in use, about pivot 162 and along track 168 in synchronism with the beam, and a tyre supporting and transporting arrangement 12. The tyre supporting and transporting arrangement comprises two substantially identical assemblies 32, 34. Each assembly has two arms 56, 58 supporting rotatable pins 76, 78, and two rams 86, 88 the piston-rods of which are connected to rotatable pins 80, 82 slidable in slots in the arms, and at least one of the pins is rotated by a drive motor 190. The assemblies are movable along base 30 by a drive arrangement consisting of a motor 66 and a drive chain 64. The assembly 32 is secured to the chain whilst the chain passes around a sprocket 72 fast with the output of a motor 70 mounted on the assembly 34. The source 17 which is rotatable is carried by an arm 122 pivoted at 128 intermediate its ends and slidably supported in a guide 120 carried by an L-shaped member 116 slidable along way 118. A second radiation source 114, mounted on a telescopic arm 110 which is pivoted at 112  on a vertically movable L-shaped arm 108, is provided for "over-the-horizon" inspection. When the source 114 is operative the receiving unit is canted on pivots 176. The images received by the unit 16 are transmitted to a television screen (not shown). Alternatively, the source 17 produces a 360 degree beam and may be provided with a rotatable shield which produces the beam. In operation, the assemblies 32, 34 are positioned so as to receive a tyre feed conveyer 20 (Fig. 6). After a tyre T has been appropriately positioned, the motor 70 is energized to move the assembly 34 towards assembly 32 so that the pins 76, 78, 80, 82 now project axially inwardly of the beads. The conveyer is moved away, and the motor 70 is de-energized and motor 66 is energized to move the assemblies to an inspection station (Fig. 8) in which the source 17 will be within the tyre. The rams 86, 88 are now operated to cause the pins to firmly engage the beads. When the beads are firmly engaged, or simultaneously with operation of the rams 86, 88, the assembly 34 is moved away from the assembly 32 to spread the beads. Bead to bead inspection is now effected whilst the tyre is rotated. The cycle of operations is now reversed and the inspected tyre is removed by the conveyer. For wide tread tyres and green tyres in their cylindrical form the radiation source 17 and receiving unit 16 remain stationary whilst the assemblies 32, 34 are moved to enable inspection of the cylindrical tread region or green tyre respectively. Control may be manual or automatic.
