Title: Improvements in or relating to catalytic conversion of carbon oxides with hydrogen
IPC: C07C1/04
Filed: 1949-01-26
Abstract: <PICT:0658848/III/1> Iron catalysts for use in the catalytic conversion of carbon monoxide and hydrogen are obtained by subjecting iron oxide mixed with a small amount such as 2-8 per cent of carbon, and from 0.5-10 per cent of conventional promoters such as alkali metal compounds or the oxides of chromium, zinc, magnesium, manganese or rare earth metals, to combustion and sintering in an oxidizing atmosphere at 2200 DEG  to 2500 DEG  F., preferably followed by reduction in hydrogen at 600-1100 DEG  F.  The iron oxide may advantageously comprise sintered pyrites ash, from 2-15 per cent by weight of oxides of antimony, vanadium, manganese or copper or 25-50 per cent of aluminium oxide being incorporated prior to sintering with carbon.  In the Figure, pyrites concentrate from bin 1 is roasted at 700-1200 DEG  F. in furnace 5 to reduce the sulphur content and passed via lines 11 and 18 to a moving grate 21 and sintered at 2000-2300 DEG  F. in an oxidizing gas drawn downwardly through the mass by suction pump 29, thus combusting the residual sulphur and sintering the oxide mass.  The latter, collected at 33, passes via 37 to a crusher 39 and hence to a mixer 43 where 5 per cent by weight of coke and 5-10 per cent of water which may contain 0.5-3 per cent of potassium carbonate or fluoride, are added. The mixture is then subjected to combustion of carbon and consequent sintering on the moving grate 49, any portion of the layer being exposed to sintering temperature for about one minute. The oxidizing gas is drawn downwardly through the mass as before. The product is crushed to 30-200 microns size and reduced in conventional manner.

Abstract: 411,218. Focusing and switching electric battery lamps. EVER READY CO. (GREAT BRITAIN), Ltd., and TERRY, M. C., Hercules Place, Holloway, London. Jan. 26, 1933, No. 2589. [Classes 39 (ii) and 75 (iv).] In an electric battery lamp switching and focusing are both effected by turning the end cap relatively to the casing, initial movement of the cap closing the electrical circuit and further movement causing the bulb to move further away from the reflector. In the form shown in Fig. 1, pins 5 carried by resilient arms 7 secured at 8 to the interior of the casing 1 project through holes in the casing and engage with inclined slots 6 in the end cap 4, removal of the cap being permitted by depressing the pins. Alternatively, the pins may be rigidly secured to the casing, the slots terminating in outwardly pressed troughs 30, Fig. 3, which latter Figure shows a slot 6<a> with a sinuous upper edge 29. The cap is formed with a knurled periphery 28 and it may engage the battery 19 directly or through the intermediary of a cup-shaped member 26 having arms 27 to receive a spare bulb. The bulb 9 is screwed into a socket 10 which is slidable within a sleeve 11 carried by a disc 12, the socket containing an insulating member 13 carrying a contact pin 14 adapted to connect the bulb terminal 16 to the battery-terminal 18. The bulb is held in its normal position by means of a coiled spring 20 disposed between the sleeve 11 and an insulating washer 21 on the end of the socket. The terminal 18 is normally held out of engagement with the contact pin 14 by means of an insulating ring 22 slidable within the casing 1 and urged against the upper end of the battery 19 by a coiled spring 24 in engagement with the disc 12, movement of the ring 22 being limited by a flange 25 engaging the washer 21. In modifications the slots may be of zig-zag formation to produce a step-by-step movement of the cap, the pins and slots may be replaced by spring- pressed balls and aligned indentations of partspherical form, the positions of the pins or balls and the slots or indentations may be interchanged, the cap may be screwed on to the casing, and the cap may be moved into and out of engagement with a battery which is in permanent connection with the filament.
