The catalyst may be a soluble halide, sulphate, nitrate, chromate, formate, acetate, oxalate, lactate, tartrate, arylsulphonate, benzoate, salicylate or glycerophosphate of an alkaline earth metal or of a metal of groups IV A , V A , VI A , VII A , VIII, I B , II B , III B , IV B  and V B  of the periodic classification of the elements according to Mendeleev, or an oxide of vanadium, manganese, rhenium, chromium, molybdenum or tungsten, which exhibits Bronsted acidity.
Patent GB-661599-A (GB)
Title: Improvements relating to the cooling of spray dried organic detergents
IPC: C11D13/12
Filed: 1949-04-22
Abstract: <PICT:0661599/III/1> <PICT:0661599/III/2> Hot spray - dried organic detergent particles are introduced into the lower part of a cooling column 17 up which passes cooling air at an average velocity of less than 25 feet per sec. and the cooled particles which have passed up the column are separated from the air leaving the column.  The hot particles are produced from an aqueous solution of detergent which falls from sprays 2 in a tower 1 to be dried by hot gas such as air flowing either up or down the tower.  From the bottom of the tower the particles are conveyed by a stream of gas either through a cyclone separator 9, star valve or air lock 10a and surge hopper 14 to the air inlet duct 16 of the cooling column 17 or they may pass directly to the duct 16 as through an air lock 6b, e.g., a star valve.  The stream of gas for conveying, i.e. atmospheric air from an inlet 8 or hot gas from the drying tower, is induced by a fan 13 to flow through a duct 7, the separator 9, a duct 11 and a filter house 12 from which the trapped fine particles are returned by a conveyer belt 58 for re-processing.  The duct 11 also receives air from the outlets of a further separator 19 and a particle classifier 34 through which, in turn, the particles from the cooling column 17 are passed, being further cooled in the classifier.  An air lock 20a is provided between the two structures.  The classifier 34 consists of an inclined framework 36 vibrated by an eccentric at its upper end and carrying a housing connected at the top by ducts 44 to the exhaust duct 11 and containing an upper coarse screen 40, Fig. 3, and a lower, fine screen 41.  Air is cooled in an intake 47, Fig. 1, and passes to manifolds 52 on each side of the classifier to be introduced between the sieve screens to cool the falling particles including those of the desired size which are caught on the fine screen 41 before discharging to packaging apparatus through an outlet 55, Fig. 1.  Other outlets are provided for the too coarse and too fine particles which are returned for re-processing.  Flexible connections 57 obviate the vibration of the inlets and outlets for air and detergent.  Air in the classifier intake 47 is cooled by evaporators therein which are fed with liquid refrigerant from a compressor 28 and a water-cooled condenser 31 which also supply an evaporator 24 in the cooling air line to the column 17.  This air line comprises also a positive displacement blower 22, compressor, or turbo-compressor, a water cooler 23 and a mist separator 25. Examples are given of working data for the plant concerning quantities of soap, rates of flow, temperatures and humidities.

Abstract: 610,620. Thick aerofoil sections; boundary layer control. GOLDSTEIN, S., and RICHARDS, E. J. April 11, 1946, No. 11195. [Class 4] An aerofoil is provided on one or each of its surfaces with a boundary layer suction slot located nearer the trailing than the leading edge, the aerofoil section being so shaped that, at all incidences within a prescribed range, the calculated potential flow velocity distribution along the or each slot-containing surface is such as not to provoke boundary layer separation, except at a position coinciding with or closely adjacent the slot, at which position an abrupt decrease of velocity in the downstream direction occurs. The invention is intended for application to very thick aerofoil sections giving low drag at low lift coefficients. Fig. 1 shows a symmetrical section, particulars of the co-ordinates of which are given in the Specification, having a thickness/chord ratio of 30 per cent and in which suction slots S1, S2 on the upper and lower surfaces, located at 80 per cent of the chord from the leading edge, are connected to a suction pump P by ducting D. The calculated velocity distribution is shown in Fig. 2, curve 1 applying to both surfaces at zero incidence, curves 2, 3 and 4 to the upper surface at increasing angles of incidence, and curves 5 and 6 to the lower surface, in all cases a discontinuity occurring in the velocity curve at a point 80 per cent of the chord from the leading edge. Fig. 3 shows an unsymmetrical section having a thickness/chord ratio of 31.5 per cent, and in which a suction slot S3 is provided on the upper surface at 69.11 per cent of the chord from the leading edge. The slots may face forwardly or rearwardly. Specification 578,763 is referred to.

Filed: 1916-08-16
Abstract: 108,717. Sykes Interlocking Signal Co., W. R., and Tarrant, R. W. Aug. 16. 1916. Miniature signals or indicators and the like.- A four-position indicator comprises a permanent magnet and an electro-magnet winding producing a resultant magnetic field according as the winding receives a stronger or weaker current impulse in one direction or the other, and two independently pivoted armatures movable in the field of the magnet and operating a tablet so as to cause it to occupy its two limit positions when both armatures are in their limit positions, and its two intermediate positions when one or other armature is displaced from its limit position. The tablet p is carried on a lever o counterweighted so as to tend to remain horizontal. The cranks r carry pins s, s<x> which are engaged by the upper ends of unmagnetized armatures e, f which are independently pivoted on a pin g, and move in a tube d around which the coil a is wound. The permanent magnet h, h<x> carries pairs of adjustable pole pieces k<1>, k<2>, k<1x>, k<2x>, which are unsymmetrically arranged, as shown in Fig. 2, so that the armature e can contact with the pole-piece k<1x> but is stopped by the tube d while clear of the polepiece k<2>. Similarly, the armature f can contact with the pole-piece k<1> but not with the pole-piece k<2x>. A strong impulse causes both armatures to move in one direction and the tablet is moved to a limit position as shown in the Figures. A weak impulse in the reverse direction causes the armature f, which is not in contact with its pole-piece, to move away from its position shown and to engage the pin s and move the tablet until the pin s<x> is stopped by the armature c which is held by its pole-piece. The tablet then occupies the position next to the limit position shown in Fig. 1. The remaining two positions are occupied when the armatures are moved towards the other poles by a reversed strong current and by a weak current in the same direction as the strong current first mentioned above. Thus the inscription p<2>, p<3> on the tablet can only be exhibited following respectively inscriptions p<1>, p<4>. In a modification, each pole-piece of the permanent magnet carries an upright bracket of non-magnetic material serving to support two stops for limiting the movement of the armatures, the stops being respectively of magnetic and non-magnetic material and the magnetic stop on one pole-piece being opposite to the non-magnetic stop on the other polepiece.
