An electrolytic furnace for the production of aluminium has a continuous self-baking electrode supplied with current by vertical contact rods 15a, 15b inserted into the top 4 of the unbaked carbonaceous anode, the rods being arranged in at least four rows and supported and supplied with current by an assembly of longitudinal supply conductors 9 which all extend between the inner two rows of contact rods so as to give ready access to the rods from the sides of the furnace. The aluminium bus bars 9 are also extending between the inner rows of contact rods and adjustably suspended by spindles 10 with jacks 11 on the furnace frame 7. The contact rods in the row nearest the assembly of supply conductors on each side of it may be directly supported by the assembly, while the outer rows of contact rods are supplied with current and supported by lateral arms projecting transversely from the assembly. The bus bars 9 have bent out parts 12 forming lateral arms with outer tips 13 bent to provide wide contact through brackets 18 with vertical aluminium strips 17 carrying at their lower ends metal cushions 16 bolted or welded to the top ends of the vertical contact rods 15a, 15b. The brackets 18 are also clamped to supporting arms 14 projecting from the iron frame 8, which takes the weight of the electrode. The strips 17 of the inner rows of contact rods are preferably clamped directly to the frame 8. The bus bars 9 are arranged in two groups one above the other within the frame 8 and are spaced by current' supply conductors 19. The bars 9 may be supplied with current at both ends and may be interconnected at intervals by metal spacing blocks assisting even distribution of current. Compensating bus bars may extend continuously over each group of bus bars. Two bent parts 13 from the bus bars may be attached to each contact rod. The permanent iron casing 5 of the electrode is supported by rods 6 from the furnace frame 7. Specification 526,696 is referred to.

Abstract: 860,400. PN junction diodes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 3, 1959 [July 17, 1968], No. 23988/58. Class 37. A PN junction diode is made by alloying donor (acceptor) pellets to opposite sides of a P(N) type semi-conductor (e.g. germanium) body to such a depth as to produce a continuous region of N(P) type material extending between the pellets, and subsequently reducing the area of the PN junction defining the boundary of this region by reducing the thickness of the body at the junctions. In the example (Fig. 3), in which a cylindrical zone 3 is produced by using circular pellets, the junction area is reduced by applying a voltage between the P and N regions and electrolytically etching in a 10% solution of caustic potash. The capacitance of the junction may be continuously measured during etching to allow fine control of the final capacitance.

Abstract: 610,825. Walls. CHEECOL PROCESSES, Ltd., KEEBLE, H., and SNELGROVE, E. C. Sept. 6, 1945, No. 23014. [Class 20(iv)] A wall consists of spaced vertical pillars and panels having vertical edges shaped to engage grooves in the pillars, the panels being clamped in position bv tie-rods or tensioning-means extending from one pillar to the next pillar, the tensioning-means of each pair of pillars being independent of the tensioning-means of the next pair. The tensioning may be effected by turnbuckles, in which case, when a double wall is being erected, it is necessary to leave room for a hand to be inserted under the panel for turning the turnbuckle, and then finally to force the panel downwards into its proper position. A compression spring, protected by a waterproof wrapping, may be interposed between one end of the turnbuckle rod and the pillar to form a resilient anchor. The tie rods may be housed in horizontal grooves in the upper edges of the panels. The tie rods may be hooked on to the reinforcement of the pillars which are suitably cut away to expose the reinforcement, between which and the tie-rods vibration - absorbing sleeves may be used. Alternatively, if hollow pillars are used, the tie rod ends may be embedded in blocks which fit in the pillar cavities. The wall may be stiffened against wind pressures by ties which run vertically from anchoring blocks to the top of the wall, the ties being accommodated in the cavity space, if a double wall is to be stiffened, or through hollow pillars. The vertical tie rods may be braced by diagonal rods. As shown, the wall is built upon a horizontal beam 11 having two ribs 12 which position the correspondingly grooved pillars 1 and the lower panels 3. The ties comprise rods 7 which pass through holes in the pillars 1, plates 10 on the rods which abut against the pillars, and nuts 8.
