Filed: 1918-03-12
Abstract: 121,873. Ransome & Co., A., and Lambley, F. A. March 12, 1918. Saws, setting.-In a machine for swaging and side-dressing the teeth of band and other saws, the saw is fed intermittingly by a finger 23 carried by a lever 22 and adapted to engage the teeth of the saw, and while the saw is stationary one tooth is swaged to press the metal out laterally on both sides by a rotary tool 6 coacting with a stationary anvil 4, and a previously swaged tooth is side-dressed between a pair of laterally acting tools 48. The saw is clamped by a jaw 24 actuated by a cam on a shaft 28, and both the jaw 24 and the swaging-tools are mounted on a slide 3 which is moved upwards on inclined guides 2 and against the action of a spring 18 to move the tools out of the path of the saw teeth while the saw is being fed. The dressing- tools 48 are carried by arms 47 adapted to rock laterally on pivots 46 mounted on a block 45 pivoted to the machine frame at 44. Conical rollers 42 are carried by arms 41 projecting from a shaft 40. When this shaft is rocked, the rollers 42 rock the arms 47 first on the pivot 44 until they are arrested by a stop on one of the tools 48 engaging the saw tooth to be dressed, and then on the pivots 46 to cause the tools to operate upon the tooth. When the rollers 42 are raised, the arms 47 are pushed back by a spring 51 and are separated by a wedge 52.

Title: Process of preparing a nickel-aluminium or a cobalt-aluminium alloy from a spent raney-catalyst
IPC: C22B5/06
Filed: 1959-02-11
Abstract: In a process of preparing a nickel-aluminium or cobalt-aluminium from spent Raney catalyst by oxidising the catalyst and reacting it exothermically with aluminium, (see Group II) the spent catalyst is oxidised to nickel or cobalt oxide at least partly with a nitrate e.g. aluminium, cobalt, nickel, sodium, potassium, calcium or, preferably ammonium nitrate.  The oxidation of the catalyst may be wholly by means of the nitrate but is preferably partly by means of an oxygen-containing gas. Thus an aqueous solution of a nitrate and a water suspension of the catalyst is mixed and the mass evaporated to dryness.  The dry mass is then heated in air to 600 DEG C. or heated whilst air is passed through it.  In the latter case the air is controlled so that the temperature does not exceed 900 DEG C.ALSO:In a process of preparing a nickel-aluminium or cobalt-aluminium alloy from spent Raney catalyst by oxidizing the spent catalyst and reacting it exothermically with aluminium, the oxidation is carried out at least partly with a nitrate, e.g. aluminium, cobalt, nickel, sodium, potassium, calcium or, preferably, ammonium nitrate.

Title: Improvements in the recovery of lead and silver from ores and metallurgical products
IPC: C22B1/08
Filed: 1921-02-11
Abstract: Silver and lead are recovered as chlorides from sulphide ores, concentrates, slimes &c., particularly those containing lead, silver and zinc, by treatment with a chloridizing gas at such a temperature that only the lead and silver are attacked.  The operation is conducted in a closed furnace or retort in the absence of air, and intimate contact between the gas and the solid is ensured by rabbling, passing the gas through layers of the ore &c, or by allowing the latter to fall through an atmosphere of the gas.  The treatment is preferably carried out between 450-600 DEG  C. and the chloridizing gas may be generated in situ. In an example a Broken Hill ore containing silver, lead, zinc and copper is treated with gaseous hydrochloric acid at 450 DEG  C.  The silver and lead are leached out from the treated product either separately or together by suitable solvents in the known manner.
