Title: Improvements in or relating to anodes for electrolytic cells
IPC: C25B11/04
Filed: 1967-05-04
Abstract: 1,128,136. Oxidizing palladium alloys; coating with palladium alloys; electrolyis of halides. TSURUMI SODA CO. Ltd. March 4, 1967 [May 4, 1966; Sept.22, 1966), No.20706/67. Headings C7A, C7B, C7F and C7U. Anodes intended for the electrolysis of aqueous solutions of halides are made wholly or partially from alloys of palladium with platinum or rhodium, having by weight 3%-80% palladium and 97%-20% rhodium or 5%-80% palladium and 95%-20% platinum, and are given an oxide surface layer by heating at 180‹C.-1, 350‹C. in an oxidizing atmosphere or by electrolytic oxidation in a fused salt bath. Preferably the oxidizing atmosphere is air but oxygen may be used. If the salt bath is used it may be made up of sodium sulphate or sodium nitrate. The rhodium-palladium alloys may be made by sintering mixtures of metal powders and the platinum-palladium alloys by fusing their constituents in a vacuum electric furnace. They may make up the entire body of the anodes, or may be coated on other electro-conductive material, suitably by electrolytic plating or by application of a solution of chlorides of their constituents in reducing organic solvents such as alcohol and lavender oil, followed by heattreatment to form the alloys. The use of alloys of platinum and palladium with Pt:Pd ratios by weight of 6:4, 3:7 and 5:5 and of alloys of rhodium and palladium with Rh:Pd ratios of 7:3 and 5:5 is discussed. Titanium substrates may be plated with a platinum-palladium alloy having a weight ratio of 6:4 by electrolysis in an aqueous bath containing sodium phosphate, ammonia, chlorplatinic acid and dinitro di-ammino palladium or may be coated with a rhodium-palladium alloy having a weight ratio of 7:3 by application of the metal chlorides in alcohol and lavender oil and their reduction, and the alloy coatings so formed oxidized in air.

Title: Improvements in and relating to the production of drop-forgings
IPC: B21J5/00
Filed: 1954-07-16
Abstract: 767,750. Forging; continuous casting. BOHLER & CO., AKT.-GES., GEB. July 16, 1954 [July 24, 1953], No. 20761/54. Classes 83 (1) and 83 (4). In the production of drop forgings, parts of a continuous casting are used as the basic workpieces. The continuous casting, which is preferably of steel and is stated to have a fine grain structure, passes through a succession of cooling zones, which may be controlled individually. The fine grain of the casting may be improved by subjecting it, during solidification, to mechanical, electrical, or magnetic vibrations. The workpieces from the continuous casting are annealed before drop forging; the latter -may be performed using the residual heat of the casting. The forgings may subsequently be tempered.

Abstract: 907,373. Turbines, elastic fluid; axial flow compressors. DAIMLER-BENZ A.G. June 8, 1961 [June 14, 1960], No. 20775/61. Classes 110 (1) and 110 (3). An operating ring driven in a circumferential direction for adjusting pivotably mounted guide vanes in a turbine or compressor is suspended in the machine housing so as to be movable in the plane of the ring by means of a joint quadrangle or kinematically equivalent means with the centre of the ring offset from the centre of the machine. Guide vanes 12 in a gas turbine are adjusted by means of a lever 17 pivoted to a ring 15. The ring is driven circumferentially by a linkage 14 operating a bell-crank 13 with a slot engaging a ball-ended spigot 16. The ring is suspended in the turbine housing A by two links 19, 20 whose projected axes intersect perpendicularly at the centre 21 of the ring. The centre 21 of the ring is offset from the centre 23 of the rotor 18 by an amount 24 along the bisector of the angle 22 towards the links so as to reduce the error due to transverse movement of the ring during adjustment of the guide vanes.

Abstract: 863,645. Billet piercing. BEISNER, K. July 2, 1957, No. 20853/57. Class 83 (4). Ingots and the like are pierced whilst hot by means of an annular punch 1 which removes a core from the ingot and is cooled during piercing. The punch comprises concentric outer and inner walls, 1, 2, spaced apart by radial ribs 4, Fig. 3 (not shown), on the inner tube, which form supply and return ducts for the coolant. The latter which may be water, air or a mixture of water and air, is supplied through an inlet pipe 8 and discharged by an outlet pipe 11. The punch may have a restricted bore 12 to facilitate removal of the punched-out core 13 of the ingot. In this case the coolant may be discharged through openings 16 into the annular space 15 between the core and the punch. The piercing is effected at 800-1100‹C. An external helical rib may be provided near the leading end of the punch for rotating it to facilitate accurate guiding during piercing.

Both filaments are energized to out gas metal parts of the apparatus, but only one is used in operation of the ion source. This source is mounted on a flange ready for attachment to other apparatus, and is thus not enclosed. The source may be used in a mass spectrometer, for ion bombardment, or as an ionization gauge.

The terminal member 16, Fig. 5, has a thin edge portion 36 adapted to enter between the bifurcated flanges on the element 18, and protruding pins 37 which engage in the sockets 23. A projection 38 on the member 16 has a bearing surface 39 which contacts a surface 31 on the element 19, and its upper face is contoured to engage with the lowermost coupling element 13 adjacent the member 17.

The pins 37 are engaged in the sockets 23 and the member 16 pivoted about the pins so that its edge portion 36 passes through the associated side slot of the slider. The slider is then raised to engage the two rows of coupling elements.
