Filed: 1938-08-17
Abstract: 518,366. Motor driving-arrangements. VIDAL C. H., and S. E. M. DEVELOPMENTS, Ltd. Aug. 17, 1938, No. 24278. [Class 35] Epicyclic gear, by which an electric motor is coupled to its load, such as the driving-wheels of a vehicle, is controlled by the motor current, so that when the current reaches a certain limit the transmission ratio is increased. The figure shows a pinion 9 on the motor-shaft 5 meshing with planet-wheels 11 on a carrier 10 secured to the driven shaft 6. The planet wheels 11 also mesh with an internal gear 14 on a member 13. Splined to the member 13, so as to rotate with it, is a member 15. Normally the member 15 under the action of a spring 20 engages a friction face on a member 17 secured to the shaft 6, so that the whole gear rotates as one piece. When the motor-current exceeds a certain limit a magnet 21 disengages the member 15 from the member 17 and causes it to engage the fixed face of the magnet, when the gear operates as a reduction gear. The magnet 21 may be in series with the motor-armature, but is preferably energized through a relay; two circuits for this purpose are'described.

Title: Improvement in process for the production of amines
Filed: 1937-09-06
Abstract: 501,763. Amines. KODAK, Ltd. Sept. 6, 1937, No. 24288. Convention date, Sept. 5, 1936. Drawings to Specification. [Class 2 (iii)] Amines are manufactured from compounds capable of being aminated, i.e. alcohols, secondary amines or, when a hydrogenating catalyst is present, mixtures of aldehydes and hydrogen, and aminating agents, i.e. ammonia or primary amines, by spraying a liquid compound to be aminated into an atmosphere of an aminating agent under pressure. Dehydrating or hydrogenating catalysts, e.g metals of group VIII of the periodic system or various oxides, may be suspended in the compound to be aminated. In an example, butyl alcohol is mixed, in a storage tank fitted with a stirrer, with a catalyst prepared by heating a nickel aluminium alloy with caustic soda. The mixture is pumped through a heat exchanger into a reaction chamber, preferably of elongated. construction, containing an atmosphere of ammonia under relatively high pressure and temperature, e.g. 200-1500 lb. per sq. in. and 135-500‹ C., preferably 800-1000 lb. per sq. in. and 215-225‹ C., the temperature being maintained by circulating steam, either saturated and under pressure or superheated, through a jacket surrounding the reaction chamber. A liquid containing butylamine and dibutylamine collects at the bottom of the chamber and is worked up for the separation of its constituents. The butyl alcohol may be replaced by dibutylamine, or by butyraldehyde, in which case hydrogen is also supplied to the reaction chamber. The process may also be applied to the production of amylamines, e.g. from amyl alcohol or valeraldehyde, or of other amines, e.g. propylamine or ethylamine.

Abstract: 532,746. Electric cut-outs. CREE, J., and WORME, D. A. Aug. 24, 1939, No. 24354. [Class 38 (i)] A magazine fuse plug comprises an externallythreaded hollow body 1, Fig. 2, of insulating material and open at one end, a hollow capsule 12 of insulating material which carries a number of independent fuse elements 14 and is inserted in the open end of the body 1, a metallic shell 21 which screws on to the body 1 to clamp the capsule in place and to make contact with one end of each fuse element, and a device operable by a knob 30 for selectively making contact with the other ends of the fuse elements. Each fuse element consists of a strip 14, Fig. 11, of fuse metal secured to end strips 15 of metal normally infusible under working conditions. The upper end of each element is inserted in a slot formed in a groove 18, Fig. 2, in a disc 16 of insulating material which rests on the upper end of the capsule 12. The selector consists of a spindle 26 which slides in an axial bore in the capsule and the body and has a knob 30, an arm 32, and a collar 31 that is engaged by a leaf spring 33. In use, the lower end of the selector makes contact with the central contact of a socket into which the device is screwed, while the arm 32 rests on the upper end of a fuse element. When a fuse blows, the knob 30 is drawn outwards slightly, and is turned so as to move the arm 32 into another groove 18 where it makes contact with a new fusible strip.

Patent GB-746780-A (GB)
Title: Improvements in or relating to hydrometallurgy of nickel and cobalt
IPC: C01G51/06
Filed: 1953-09-07
Abstract: Substantially cobalt-free nickel-bearing solutions are recovered from liquor containing both metals in the form of sulphates or carbonates by adjusting the metal content of the liquor to up to 100 grams/litre of dissolved cobalt plus nickel for carbonate solutions and up to 135 grams/litre for sulphate solutions, 1-4 mols of amonium carbonate per mol of dissolved cobalt plus nickel salts and sufficient available ammonia to retain cobalt and nickel in solution under atmospheric conditions, heating the solution under pressure to above 140 DEG C. till precipitation substantially ceases and separating the precipitate containing cobalt carbonate from the solution.  Where the nickel : cobalt ratio in the liquor is less than 1 the treatment may take place in two stages, a substantially nickel-free cobalt precipitate being obtained in the first stage, the precipitation in the second stage being continued till the solution is substantially cobalt free.  Heating preferably takes place in an atmosphere of hydrogen.  In carbonate solutions the mol ratio of free ammonia : dissolved nickel and cobalt may be 1.5-2.0 but is preferably higher and up to 4.0, a good range being 2.5-3.5.  To ensure selective precipitation the solution should contain a proportion of ammonium carbonate which varies with the ratio of nickel : cobalt, the mol ratio of ammonium carbonate : nickel + cobalt being, for example 1 : 1 when the nickel:cobalt ratio is 1.5 or lower and 3:1 or 4:1 when the nickel:cobalt ratio is higher.  The proportions given above are varied slightly in sulphate solution.  The cobalt carbonate precipitate and the residual solution may be separately treated to recover the metals in metallic form.  (See Group II.)ALSO:Cobalt carbonate precipitated from a nickel-and cobalt-containing solution (see Group III) is treated to recover cobalt as metal by slurrying the carbonate in water to form a 25-40 per cent slurry and subjected to an elevated temperature of 100 DEG F. to 500 DEG F. or above, preferably 200-450 DEG F., and to a partial pressure of at least 100 lbs./sq. in. gauge of a non-sulphidising reducing gas such as hydrogen.  The resulting slurry of cobalt metal is cooled and the metal powder dried.  The solution resulting from cobalt carbonate precipitation may be treated to recover nickel and any residual cobalt as metals by adjusting the ammonia and carbonate contents and treating the liquor at different but increasing elevated temperatures with a reducing gas to recover a low cobalt-content nickel powder and finally a low nickel-content cobalt powder.
