Title: Process for separating aluminium chloride from other metallic chlorides
IPC: C01F7/62
Filed: 1929-05-17
Abstract: 325,440. Imperial Chemical Industries, Ltd., Bennett, N., and Dodd, H. May 17, 1929. Phosgene.-Aluminium chloride is purified by the formation of a liquid compound with phosgene, separating fom the insoluble impurities, such as metallic chlorides, which are substantially insoluble, and decomposing the liquid compound so formed, for example, by heating to approximately 60‹ C. at ordinary pressures to give phosgene, and to leave a residue of anhydrous aluminium chloride. The purification may be applied to aluminium chloride already formed, by passing phosgene through crude aluminium chloride at ordinary temparature and removing the liquid compound. Alternatively in the manufacture of aluminium chloride from bauxite or the like by means of phosgene, excess phosgene may be used, and the mixed vapours cooled so as to separate the liquid. The phosgene obtained from the decomposition thereof may be re-employed in the process.

In a method of piercing a hole 11 in a workpiece 9 by a high energy beam 21, the surface of the workpiece in the vicinity of the hole is provided with a covering layer 15 which is later removed. This layer prevents damage to the hole near the surface. The layer 15 may be of refractory metal such as tungsten and has a spacer 17 formed around the hole to be pierced. Alternatively a separate spacer ring may be used. An electron beam 13 first pierces a hole in the layer 15 and then the centre part of the beam pierces the hole 11 in the workpiece. The beam may be pulsed. After piercing, the layer is removed and the metal workpiece (51), Fig. 5 (not shown), may be then electroplated with copper (55). In another embodiment, Fig. 1, a workpiece (1) of nickel is provided before piercing with a thin layer of copper (5). Subsequently the layer is removed by grinding or etching. Before grinding the hole may be filled with wax which is later removed by melting or by a solvent. For piercing large numbers of holes, the beam may be controlled by a programmed device. The hole may be of circular or elongated cross-section and may extend only partly through the workpiece. The workpiece may be an electrode for an electron tube, or a diaphragm for a mass spectrograph or an electron microscope. Reference is also made to a LASER beam.
