Patent GB-208555-A (GB)
Title: Improvements in the process of producing decolorizing carbon
IPC: C01B32/336
Filed: 1922-11-20
Abstract: 208,555. Algemeene Norit Maatschappij. Nov. 19, 1921, [Convention date]. Charcoal. - Decolorizing carbon is produced from predistilled carbonaceous material of vegetable, animal or mineral origin, such as charcoal or coked peat, by a two-stage continuous process in a vertical or inclined retort comprising a first stage in which the charge, descending by gravity, is scoured by the upward passage through it of the reaction gases from the second stage, and a second stage in which the charge is activated by heat and gases. Suitable activating gases are steam, carbon dioxide or monoxide, retort gases, water-gas coke-oven gas, producer gas, combustible gases, air, hydrogen or chlorine or mixtures of these gases and they may be introduced into the bottom of the retort in a comparatively cool state, so as finally to cool the charge. In addition solid activators, such as calcium or magnesium carbonate or chloride, or slaked or quick lime, may be added to the charge. On entering the first zone, the reaction gases may be mixed with hot substantially inert gases, and the whole, together with any distillation products, is preferably withdrawn at a short distance from the top of the retort to obviate the choking of the conduit. The heating of the retort may be external, such as by means of the retort gases, internal, such as by injection of hot combustion or combustible or burning gases, or both internal and external. Zones of different temperatures may be maintained in the retort and into each zone the gas having the optimum activating effect at that temperature may be injected. An example shows the treatment of wood charcoal using steam as activating gas in a vertical retort having serially connected heating chambers and a sluice discharging the treated material into a detachable water-sealed vessel. Specification 167,195 is referred to. The Specification as open to inspection under Sect. 91 (3) (a), is not limited to gravity-feeding of the charge. Volatile chlorides are also specified as activating gases, and ammonium and sodium chlorides as solid activators. This subject-matter does not appear in the Specification as accepted.

Brussels sprouts are removed from their stalk by passing the plant through inner and outer coaxially rotating cutting means, the outer cutting means cutting sprouts from their butts and the inner cutting means cutting the butts from the stalk. In one embodiment (Figs. 1, 3) a machine includes inner blades 8a and outer blades 8b arranged to rotate about an axis XX along which the sprout plant is passed. The blades 8a, 8b are carried by radial arms 9a, 9b urged inwardly by springs 11 and slidably mounted in blocks 10a, 10b secured to a rotating annular plate 5. The arms 10b carry rollers 12 which engage on the cleared stalks thereby to resiliently position the outer blades 8b in radially spaced relationship from the stalk, the inner blades 8a which lie behind the outer blades 8b resiliently following the contour of the stalk. Driving means are described which rotate the plate 5 and contra-rotate spiked rollers 17, 18 which engage the root end of the stalk to draw it through the machine. Concave guide rollers 34, 35 carried on pivoted arms 36, 37 are urged by a spring 43 and cam 42 means to engage round the plant at the input end. A collecting trough 32 is provided. In another embodiment (Fig. 5), a cutting head 60 is carried by an open ended cylinder 63 which is rotated about an axis XX. The cutting head 60 includes six blade mountings 66 each carrying an inner blade 67 and an outer blade 68 and each mounting 66 is pivoted, as at 69. A collar 73, arranged to move axially of the cylinder 63 by manual operation of a handle 70, is provided with an upper inclined surface which engages with a camming action the blade mountings 66 whereby the mountings may be pivoted 69 to adjust the radial distances of the cutting edges of the blades 67, 68 from the plant feed axis XX. In a further embodiment (Figs. 9, 10) inner blades 113 and outer blades 121 are carried respectively by radial pins 131, 133 slidably mounted in bores 130, 132 in a rotary housing 123. Each pair of pins 131, 133 is urged outwardly by springs 112, 134 to engage a lever arm 129 on a centrifugal weight 107 pivoted at 108 to the housing. On rotation of the housing 123 the centrifugal weights 107 are thrown outwardly to pivot the lever arms 129 and hence urge the inner blades 113 to contact the stalk of a sprout plant being passed centrally through the housing 123, the arrangement being such that pins 131 carrying the inner blades 113 have a smaller radius arm from the pivot 108 and thereby control the radial spacing of the outer blades 121 from the stalk.

Filed: 1938-11-10
Abstract: 509,112. Copper; carbon monoxide. NORDDEUTSCHE AFFINERIE. Nov. 10, 1938, No. 32752. Convention date, Dec. 20, 1937. [Class 82 (i)] [Also in Groups III and IV] In a process for dissolving and re-precipitating copper in metallic form, the copper is dissolved in a solution of cupric sulphate containing free sulphuric acid with the aid of carbon-monoxide passed into the solution under a higher pressure than atmospheric and preferably at elevated temperature, whereby a soluble double compound of cuprous sulphate and carbon monoxide is formed which is decomposed with the precipitation of copper and the re-formation of copper sulphate and carbon monoxide which latter substances may be subsequently re-used. The decomposition of the copper double compound may take place either on raising the temperature or lowering the pressure or both, and the copper is used in such a form as to present as large a surface as possible to the reagents and a constant fresh contact is ensured by movement of the copper on the liquid or both, while it is arranged that the copper is only partly covered by the reagent when at rest. The reaction may take place in a pressure-tight container provided with stirring mechanism, the copper being in the form of granules, in a rotary drum in a closed-circulation system under elevated pressure by alternately supplying and withdrawing heat without the necessity of compressing the carbon-monoxide each time, or in a shaft-shaped chamber, the copper being in the form of shavings of bars irrigated from above with acidulated cupric sulphate solution, while carbon-monoxide enters from above or below. Further, a solution of sulphate saturated with carbon-monoxide may be pumped through the copper. The reaction is assisted by the formation with the impurities present in the copper of local couples or by catalysts such as halogen ions ; in the former case, the impurities are removed by filtering, preferably after cooling. The access of atmospheric oxygen is avoided. Instead of or in addition to cupric sulphate, a copper salt of fluoboric acid, phosphoric acid or an aromatic sulpho acid such as benzene sulphonic or cresulphonic acid may be used, and instead of or in addition to carbon monoxide use is made of unsaturated hydrocarbons such as ethylene, acetylene, butadiene or derivates thereof such as alcohols, aldehydes or carboxylic acids, for example ally] alcohol, acrolein, crotonic aldehyde, acrylic, crotonic, propiolic, maleic and cinnamic acids.
