Title: Process for reducing low grade ores
IPC: C22B23/02
Filed: 1953-01-19
Abstract: 758,358. Extracting cobalt and nickel. SOC. D'ELECTRO-CHIMIE D'ELECTRO-METALLURGIE ET DES ACIERIES ELECTRIQUES D'UGINE. June 19, 1953 [June 21, 1952], No. 17080/53. Class 82(1). Low-grade ores containing nickel and/or cobalt are selectively reduced by mixing the molten ore with a molten metallic reducing bath, e.g. of iron, ferro-nickel or ferro-cobaltnickel, in which the quantity of reducing agent e.g. iron, is maintained substantially greater than that necessary to reduce all the nickel and/ or cobalt, effecting continuous contact between ore and metallic bath as in a continuously rotating container and tapping off the metallic bath enriched in nickel and/or cobalt. A strong reducing agent such as aluminium or silicon may be added, for example at intervals in the form of ferro-silicon, thereby helping to maintain the temperature in the container. Fig. 6 shows a rotatable container a suitable for carrying out the process. The ores and molten metal may be continuously introduced through the hopper b, the enriched metal being tapped off at c and the exhausted slag overflowing at o. A screen s acts so as to skim the ore and prevent any reducing agent, which may be added through the tube m, being carried away. Ribs h aid the mixing of the ore; in alternative forms of container the ribs may be omitted and the mixing improved by making the container of non-ciruclar cross-section.

Abstract: 582,309. Gear-cutting. WRIGHT, S. B. Sept. 18, 1944, No. 17773. [Class 83 (iii)] In a machine for rounding the ends of gearwheel teeth, a spindle carrying eccentrically one or more cutters is moved axially to bring the cutters into contact with the work and oscillated to produce the cutting action. The work is carried by a spindle 1 in a headstock 16, angularly adjustable by a base 17 and clamp 18 on the universally-adjustable' table 13 of the machine. The head 23, carrying the cutters 58 is mounted on a spindle 22, Fig. 4, which is oscillated in the machine column' 19 by an arm 37 thereon and a connecting rod 36 attached to an adjustable crank 35. The crank is driven from an electric motor 20 by belt gearing 27, shaft 25 and worm gearing 31. A cam groove 40 on the spindle 22 engages a fixed pin 41 to impart axial movement to the spindle during the first part of its oscillation, the pin being conical so that it may be adjusted relatively to the bevelled sides of the groove. To index the work between successive cutting operations, gearing 30 driven from the shaft 25 drives an extensible universally jointed shaft 21, rotating a worm 42, Fig. 5, driving a cam disc 43 carrying a pin 45 engaging a Geneva disc 46, connected by change gearing 48, 49 to a gear 50 on the worm spindle 1. An indexing pawl 52 engages the gear 50 during cutting and is lifted out of engagement during indexing by means of a rod 54 and a cam 44 on the disc 43. In operation, the spindle 22 is oscillated and moved axially to bring the cutters 58 up to the work, the last portion of the oscillation, which may be accompanied by further axial movement, performing the rounding operation. Reverse oscillation of spindle 22 returns the cutters to starting position, and between cutting operations the work is indexed one or more tooth spaces. Two cutters 58 may operate on opposite ends of .the same tooth or on corresponding edges of two teeth which are diametrically opposed on the work, and the work may consist of a spur, spiral bevel or other bevel gear. A spur gear may have all four corners of each tooth rounded by four cutters mounted on the head at the corners of a rectangle, one pair of cutters operating during the oscillation in one direction and the other pair during the reverse oscillation.
