Improved Method of Discharging and Hand- ling of Coal from Carts, Trucks, and Loading Banks. H. Fisher, 12, Doris-street, Kennington-road, London, S.E.— This invention relates to a device for the unloading of coal and the like from railway trucks, or loading banks, for the direct re-loading of the material into carts, ships, or other vehicles of transport, the object aimed at being to accom- plish this work in quicker time, and to make the labour lighter. The bags are filled by means of the shoots, shown in fig. 3, operated by any person, then hooked to the rope hanging between the uprights (fig. 1). The person having filled the bag ascends the steps and transfers his or her weight to the foot rest, when it, with them, descends to the ground, and the bag with its material is hoisted up to the runner, to which is attached a carrier fitted with a transferring hook and tripping lever. The person in the cart cants the transferring hook, which takes the weight of the load as the person below removes their weight from the foot rest. When material is being loaded in bulk, the transferring hook is operated by a line attached to the tripping lever (no man being in the cart), the load being conveyed to the centre of the cart by the aid of gravity, the runner being inclined for this purpose, the basket cap- sized, and brought back on the runner by means of the tripping line, which then constitutes an out-haul.

Taylor, Healey, Ossett, York. — This invention relates to apparatus of xthe type comprising a long inclined trough provided at intervals with baffles or detachable partitions, along which trough a stream of water impels the coke or other material of comparatively light specific gravity, such material passing over the baffles, whilst the clinkers or heavier impurities fall to the bottom of the trough, and are banked or piled up against the baffles. The section of the trough may be rectangular, semi-circular, or of other suitable shape in cross section. In fig. 1, the reference numeral 1 indicates the trough, to which the coke or other material treated is fed from a hopper 2, and water is fed through a flexible or jointed pipe 3 connected to a pulsometer or other pump; the material passes over baffles 4 in the trough, and is dis- charged through the spout or shoot 5. At or near the inlet end of the trough, or in other convenient position thereon, are four or other number of radial hand levers or capstan bars 6. At two points in the length of the trough it is enclosed by and rigidly connected to large wheels or rockers 7 and 8 engaging and supported by rollers 9, 10. The rollers 9 and wheel 7 are carried in a suitable sling or frame 11 attached by a knuckle joint to a vertical screw- Fig.l. Fig.2. 187 10' IO' Fig.5. threaded rod 12 working in a nut formed in a hand wheel 13 resting on a fixed bracket 14 extending from the frame- work of the apparatus, so that by rotating the hand wheel this end of the trough can be raised or lowered. As shown in figs. 2 and 3, the wheel 7 is of channel iron, and the rollers enter therein; but a T iron wheel running between two pairs of rollers would serve the purpose. Flanged plates or U pieces 15 and 16 connect the trough to the wheel; the numeral 17 in fig. 2 indicates a distance piece. The rollers 10 are carried by a fixed part of the framework of the apparatus, and the wheel 8 may be similar to the wheel 7; and may be retained in position by a round metal band 18 (figs. 4 and 5), the ends of which band are flattened out and riveted to the upright posts 19. The edges of the roller 10 are rounded off, and sufficient clearance left between such rollers and the inner sides of the channel of the wheel 8 to allow for the tilting movement of the wheel when the inclination of the trough is altered. When the clinkers or heavier impurities have accumulated to a cer- tain extent in the bottom of the trough against the baffles, the water supply is cut off, and by means of the bars 6 the trough is turned through half a revolution, tipping out the impurities, after which the trough is returned to its operative position.

Deakin, 24, College-street, London, E.C. — In the present specification, under the term heavy petroleum pro- ducts are comprised all hydrocarbons heavier than ben- zine, and under the term lighter petroleum products, benzolene, naphtha, gasolenes, and ethers of petroleum, that is to say, all the light hydrocarbons from benzine upwards inclusive. Kerosene will be usually included in the heavy products, but if the ultimate transformed pro- duct is to contain a proportion of kerosene, this hydro- carbon will be comprised in the lighter products. The process for effecting the required transformation is as follows :—In the still or retort 1 sufficient temperature is maintained to distil the light hydrocarbons in the petro- leum which is injected continuously through the pipe 3. This temperature is about 200 degs. Cent., at which all the lighter hydrocarbons, including benzene, are thrown off. The distilled vapours leave the retort 1 by the pipe 4, are condensed in any convenient way, passed into a suitable tank, and constitute the light petroleum pro- ducts. When the level in retort 1 reaches that of the outlet pipes 5, the petroleum from which the lighter pro- ducts have been removed passes to the retort 6 main- tained at a sufficient temperature to distil the desired pro- portion of kerosenes and oils, for example, up to 60 per cent, in bulk of the petroleum injected into the retort 1. When the level of the liquid in retort 6 reaches that of the outlet pipe 8, the liquid passes into the retort 9, wherein the contents distil off a further small proportion of oil. and where they are exposed to a temperature, about 10 to 20 degs. less than that in the retort 6. The purpose of this slight decrease in temperature is to prevent the boil- ing of the mass of residuals when it passes through pipe 11 to the transforming retort 12, after the retort 9 has been filled to the level of the said pipe. The distilled vapours which leave the retorts 6 and 9 by the pipes 7 and 10 respectively are condensed in the coils 13 and 16, and the resulting hydrocarbons, which correspond to the heavy petroleum products as described above, are collected in the tank 15, which separates the petroleum or products of petroleum from the water, and impurities which may have come over with it and from the uncondensed gases. From the separating tank 15 the hydrocarbons pass through the pipe 18 to the compressor 19, and finally to the sprayer 20, from which they are injected into the transforming retort 12 in the form of a very fine spray, which falls on the heated mass of residuals therein contained, the transfor- mation taking place into lighter products, and the distilled vapours passing through the tube 21 into -the coil 22. The temperature in the condenser should preferably be kept very low, at about 15 degs. Cent, so that any petroleum gases and ether which may be still in the vapours may be condensed. The gases and ether vapours are prevented from entering the tank by the bent up end of the pipe 25, and are set free through the pipe 24. The vapours in the coil 22 being condensed, the resulting liquid product passes into the tank 26, from which it may be extracted in any convenient way. This liquid is the transformed lighter product, as defined above. Kerosene and oils may possibly be sometimes found amongst the hydrocarbons in the tank 26, in which case fractional distillation is carried out by known methods, and the said oils and kerosene are again injected into the transforming retort, by means of the sprayer 20. For this purpose they may be added to the separating tank 15. (Eight claims.) HEW PATEHTS CORRECTED WITH THE COAL ARD IRON TRADES. Applications for Patents.

(106613) French Bauxite.—A correspondent of The Times Trade Supplement, who has just returned from visiting several areas of the bauxite deposits, states that of the available mines which came under notice, the analysis of the bauxite furnished was 63 to 68 per cent, of aluminium, 1 to 3 per cent, of silica. In another district it was 60 to 65 per cent, of aluminium, 8 per cent, of silica, and 10 to 12 per cent, of iron. He says he believes that it will be better to treat the ore on the spot, as in so doing a great economy will be experienced in cartage, the cost of which to-day is more than double the pre-war rate. Sites abound suitable for the erection of works, and there exists in the neigh- bourhood an abundance of water, still unharnessed, capable of providing the necessary power required by the electrolytic plant for refining the ore. Cables are already installed supplying the current for lighting the outlying villages; the same source might probably furnish the cur- rent for refining. The question of labour will be more readily solved here than elsewhere; the main d’oeuvre (chiefly Italian) has never been lacking in these parts, and is not likely to fail even after the war.
