Title: Improvements in or relating to processes for contacting gases or vapours with solid particles
Inventor: CLAYTON CHRISTOPHER GEORGE ALB
IPC: B01J8/18
Filed: 1960-09-30
Abstract: 951,247. Contacting gases with solid particles. GAS COUNCIL. Sept. 21, 1961 [Sept. 30, 1960], No. 33674/60. Heading B1L. In a process comprising passing a gas in counter current through a moving bed of solid particles in a first vessel, passing the particles to a second vessel and recycling the particles, particles of a smaller size are added to said solid particles passing from the first to the second vessel to form a gas seal therebetween. As shown in Fig. 3, adsorbent particles containing a gas adsorbed thereon which leave adsorption vessel 10 enter conduit 30 and finely divided solids from fines trap 15 are mixed therewith to form a moving plug of solids. These solids pass into separator 32 wherein a gas stream passing upwardly through the mixture from conduit 37 carries the fines into flow controller 35. The particles are fluidized therein by a stream of gas supplied through line 103 and returned to fines trap 15 by a second stream of gas from line 105. The granular particles leave vessel 32 and pass into recovery vessel 16 via conduit 36. In an apparatus as shown in Fig. 2, granular adsorbent particles are passed by gravity feed from reservoir 11 through separator 12 into adsorption vessel 10 wherein they contact e.g. benzene and cyclohexane vapours with nitrogen as carrier gas fed in at 20. Nitrogen entering at 21 elutes unadsorbed vapours (cyclohexane) from outlet 22. The particles containing adsorbed benzene pass through separator 14 into heated recovery vessel 16 wherein benzene is recovered in a countercurrent stream of nitrogen entering at 101 and leaving at 102. Particles then pass through separator 17 to recycling device 19 which may be of the type used for recycling the fines, and then to reservoir 11. The solid particles may be quaternary ammonium derivatives of clay as described in Specification 866,383. Specifications 951,245 and 951,246 also are referred to.

Abstract: 958,266. Endless conveyers. POLYMARK Ltd. Sept. 14, 1962 [Sept. 21, 1961], No. 33827/61. Heading B8A.  Laundry articles are fed by a conveyer belt 8 to one of a series of endless belts 10. Each of the latter is adapted to be displaceable downwards under a predetermined weight of clothing against the action of a spring 14 (Fig. 2). This operates a switch 16 to start the conveyer in motion. The conveyers 10 feed respective hoppers 21 which form part of a pneumatic conveyer 19 which may be of the construction described in Specification 933,090. A keyboard 23 controls the movement of the conveyer belts 10 and also determines the destination to which articles are fed by the conveyer 19. A keyboard 4 controls the selection of the particular conveyer belt 10 from the conveyer 8. Pneumatic pressure generated in a fan unit 7 brings about the transference of the articles from the conveyer 8 to the conveyers 10. Specification 850,605 also is referred to.

Abstract: 882,418. Automatic control systems. REGULA-VYUOJ, NARODNI PODNIK. Nov. 30, 1957, No. 34007/57. Class 38 (4). A system for an unspecified purpose, containing "m" exponential lags is regulated in " m+ 1 " steps computed from " m + 1 " input signal, the stepped correction signal exactly compensating for the disturbance that caused the error. A second order system S is shown, consisting of two exponential lags Ra, Ca and Rb, Cb. Two measuring devices b, c are provided, the third signal being obtained by differentiating (at d) the signal from the b device. Alternatively, 3 measuring devices may be used, or the first or second time derivatives of signals may be used. The three signals are switched, during a measuring period, to stores P by a contactor Z controlled by a timer G. The stores P are sampled 3 times by a pair of selector switches K, R also controlled by timer G. A different fraction of each stored signal is picked off potential dividers M at each sampling, and after amplification at Zb, Zb<SP>1</SP> and Zc the fractions are added to form successive steps of the correcting signal. The theory by which the necessary fractions may be calculated is discussed. The correcting signal is connected to the correcting device O by contacts U which operate alternately with contacts Z so that measuring periods and correcting periods follow alternately.

Class 20(2) A telescopic pit prop comprises an oval cylinder 1 in which is located, by means of a pin 4, a cruciform shaft 2 at the outer end of which is a head 12 resting on a shear pin 14. On overload, the pin 14 shears causing a lever 16 pivoted to the head 12 to make an electrical contact at 15 which operates a warning lamp or bell. A hole 12<SP>1</SP> permits removal of the broken pin 14. The shaft 2 has a flange 7 which seats, collapsed, on a shock absorber 6. The head 12 rests on a cube 9 which fits over the shaft 2 and is used to preset the prop by means of a wedge 11. A soft pellet or a hydraulic member (Fig. 5, not shown) may replace the shear pin 14. In a hydraulic pit prop, collapse of the head 48, Fig. 7 actuates the piston 61 of a pressure release valve 55 to collapse the prop and actuate the warning device.

Abstract: 212,658. Cowburn, T. Dec. 16, 1922. Sound-boxes, raising; stopping.-Relates to devices for raising the sound-box off a record at a predetermined position, and at the same time stopping the machine. An arm B is adjustably mounted on a hub M, in which is a split sleeve C which is adapted to engage frictionally : with the turntable pin G. The outer end of the arm is formed as a " shoe " A which lies close to the surface of the record, and has a raised part S preferably cushioned with rubber &c. At a given point, depending on the setting of the arm B. which, in the construction shown, is effected bv sliding the arm through a slot in the hub in which it is held frictionally, the shoe A passes under the needle of the sound-box, raising the latter. The part S acts as a yielding abutment for the needle, and the turntable is therefore stopped gradually, owing to the friction between the parts C, G. The friction may be regulated by screws (not shown) or by other means.

Abstract: 1313736 Continuous casting KLOCKNERWERKE AG 16 July 1970 [9 Sept 1969 28 April 1970] 34578/70 Heading B3F [Also in Division C7] In the continuous casting of steel, the molten metal flows through a supernatant layer of slag, e.g. with a lime-silicate base for the binding of alumina inclusions. The slag is contained in a tubular chamber 2 of circular or rectangular cross-section into which flows the steel 1 from a ladle. The steel 1 then flows out into a tundish trough V, possibly through a bowl 4, around pairs of ribs 5 to cause turbulence to precipitate particles and thence into moulds by way of nozzles 6. The chamber 2 has an overflow 7 for excess slag. The chamber wall 3 and bowl 4 (if used) are of high quality refractory. The wall 3, alternatively, may comprise an inner layer (8) of graphite to resist the contained slag and an outer layer of alumina. The slag could consist of 15% Al and Mg, 18% NaNO 3  and/or Ca(NO 3 ) 2 , 45% alkali silicates and/or calcium silicates and 22% fluorspar. Electric heating or a plasma torch may be used to melt the slag in the chamber 2. A protective gas is maintained in the trough if a torch is used.

In a method of building a prestressed concrete bridge by abutting and connecting prefabricated sections 1, m, n, o &c., end to end, an auxiliary girder 4 is extended from an existing span 3 to the next pier 2, and the sections are successively brought along the girder (e.g. by trolley 5) and suspended in the required positions by individual rods 6 and jacks 8, all the jacks being hydraulically interconnected. The abutting sections are successively glued together and connected by temporary pre-stressing elements 7. The jacks 8 serve effectively to support the sections under all the changing loads as building proceeds. When all the sections have been assembled on the girder 4 the latter may be displaced to bring the new span into engagement with the span 3. The two spans are then interconnected by permanent pre-stressing ropes, Fig. 3 (not shown), before the jacks are released, and the elements 7 may then be removed.
