Title: Improvements in and relating to installations for the storage and subsequent extraction of molding earth, manures and the like
IPC: A01C3/02
Filed: 1954-10-18
Abstract: 762,260. Unloading storage chambers; endless conveyers. GILSON, P. C. J. Oct. 18, 1954, No. 29872/54. Classes 78 (1) and 78 (4). A device at the bottom of a pit for removing material has a movement at right angles to its movement for extracting material so that it sweeps over the whole of the bottom of the pit. In the form illustrated the device comprises the lower run of a scraper chain conveyer C, Fig. 1, carried by sprockets 17, 17a, 25a, 25 mounted on a pair of beams 24, 24a which swing about axis X-X so that the lower run of the chain sweeps the whole of the curved bottom 5 (see also Fig. 3) of the pit. The lower run of the chain passes through arcuate slots 6, 7, Figs. 1 and 3, to deliver material to a conveyor 11. Rollers 29 carried by the beams 24, 24a engage tracks 30, 30a on the walls of the pit. The beams 24, 24a are oscillated by cables 52 passed from the beams around suitable pulleys to a winch 51, Fig. 1, driven from an electric motor 42 whose direction of rotation is reversed when a switch 61 is operated by either of two buttons 62, 63 carried by a further cable 59 which extends between the beams 24, 24a to maintain them in synchronism. The chain C is driven by a motor 19 carried by one of a pair of pivoting stands 16, 16a by which the beams 24, 24a are supported. The scraper chain C comprises scoop-shaped links 35 shown in plan in Fig. 5, the forward walls 36 of which engage the material as the chain moves in a direction of the arrow f<2>. A portion 37 on the walls 36 forms a cutting edge 38 and the links 35 are joined by spacers 39 in pairs which are connected together by flat links 32. Several installations similar to that of Fig. 1 may be disposed to feed materials to be mixed to a common conveyer.

Patent GB-810151-A (GB)
Title: Improvements in or relating to detergent compositions
IPC: C11D3/00
Filed: 1956-10-02
Abstract: A detergent composition which has a pH in aqueous solution at a temperature below 50 DEG  C. of 7.9-9.5, preferably about 8.5, and a pH of 9.4-11, preferably 10-10.5, at a temperature of 80-100 DEG  C. comprises (a) an anionic or non-ionic synthetic detergent, suitably in an amount of 15-50 per cent (dry basis) of the composition; (b) an alkali metal phosphate, which may be a polyphosphate, suitably in an amount of 25-50 per cent; and (c) magnesium oxide, preferably in an amount of 1-10 per cent, the particles of which are "masked" with a coating of a substance melting at 50-60 DEG  C., such as a fatty alcohol like cetyl alcohol, or paraffin wax, so that the magnesium oxide is "unmasked," thereby altering the pH, only when the coating substance melts. The coated oxide preferably comprises 40-60 per cent coating substance and 60-40 per cent oxide.  The detergents to be used include the alkylaryl sulphonates and higher alkyl sulphates and sulphonates, as the alkali metal, ammonium, or organic base salts; higher fatty acid amides; polyglycol ethers of aliphatic alcohols and of alkyl phenols, and polyglycol esters of higher fatty acids and of tall oil acids.  To keep the pH down at lower temperatures, acidic substances such as sodium acid pyrophosphate, or even sulphuric acid, may be included.  Other additives which may be incorporated are silicates, such as waterglass, sodium sulphate, bicarbonate, and perborate, ethylenediamine tetracetic acid, sodium carboxymethyl cellulose, polyvinyl pyrrolidone and such fluorescent dyes as 4 : 41 - bis - (2 : 2 - diaminotriazinylamino) - stilbene - 2 : 21 - disulphonic acid.  It is stated that, because of the rise in pH with temperature, the compositions are suitable for use both with proteinaceous material such as wool at relatively low temperatures and with cellulosic material such as linen and cotton at higher temperatures.

Abstract: 495,997. Drying clothes &c. UNITED STATES HOFFMAN MACHINERY CORPORATION. Nov. 4, 1937, No. 30223. Convention date, Jan. 4. [Class 34 (ii)] Clothes &c. are dried by a current of hot air drawn through a rotary perforate drum 42 mounted in a cylindrical casing 16 having a front wall formed with a flanged charging and discharging aperture closed by a hinged door 31. The aperture flange 26 projects into the front of the drum to form an annular air inlet nozzle 45a, and the drum, which is provided with hollow lifting blades 46, Fig. 3, is mounted on a stub shaft 52 supported in a bracket 53 secured to the casing and rotated through chain-gearing from an electric motor 58 which also drives a fan 67. The fan draws air through the open end of an air-heating compartment 59, mounted on the casing 16 and containing a finned steam-heated tube, and thence through circumferential apertures 28, 29 in the flange 26 and the casing respectively and the nozzle 45a into the drum. The air flows radially through the perforate wall of the drum into the casing and thence through a duct 68 connected to the fan which discharges the air into the atmosphere. The temperature of the air entering the drum may be varied by means of a slide controlling air inlet ports 65 in the top of the compartment 59. A felt &c. packing ring 50 secured to the front of the drum prevents hot air from byepassing the drum.

Title: Chromatographic separation of hydrocarbons
IPC: C10G25/03
Filed: 1963-07-31
Abstract: Straight chain paraffins are separated from a mixture containing e.g. branch chain and/or cyclic or aromatic hydrocarbons, by using a molecular sieve and desorbing said normal paraffins from the sieve to produce a first desorbate comprising 1-90 wt. per cent of the total desorbate and a second desorbate which is withdrawn as product.  The first desorbate may be recycled to feed.  Adsorption may take place at 200 to 900 DEG  F. and 10 to 25 p.s.i.a. in the vapour phase whilst adsorption and desorption rates are also specified. Desorption may be effected using a displacing agent which may be added to the feed mixture containing the n-paraffins, e.g. in amounts 0.1 to 20.0 moles of displacing agent per mole of feed.  The displacing agent may be a non-hydrocarbon, e.g.  NH3, C1-C15 primary, secondary and tertiary amines, SO2, C1 to C5 alcohols, glycols CH3Cl, C2H5Cl, CH3F, CO2 and CH3NO2.  When ammonia is used as a desorbing agent, the outlet from the bed may be shut off, the pressure allowed to rise 10 to 500% greater than the adsorption pressure and then the bed unsealed and depressurized.  Additional ammonia may be added during or after depressurizing.ALSO:Straight chain paraffins are separated from a mixture containing e.g. branched chain and/or cyclic or aromatic hydrocarbons, by using a molecular sieve and desorbing said normal paraffins from the sieve to produce a first desorbate comprising 1-90 weight per cent of the total desorbate and a second desorbate which is withdrawn as product.
