To all 'whom it may concern: c I

Be it known .that l, Huso lETERsEN, a chemical engineer', and a subject of the German Emperor, and avresident of 181 Kaiser- All'e, in the cityfofWilmersdorf, near Berlin, Kingdom'of Russia, and German Ern-A ire, haveinve'nted a certain new and useful illing for Reaction-Chambers and the Like,- of which the following is a speciiication. This invention has reference to bodies for lling reaction chambers or any other rooms or spaces, in which it is desrred to cause gases land liquids, or various gases to act upon each other or gases tocome in intimate contact with liquids of various kinds, such for instance for the purpose of Vthe bringing about of a reactionor of the absorption of gases or for various other similar and for other purposes, where such 'filling bodies are used. The body forming the subject matter of this invention is distinguished from the filling bodies heretofore in use by the fact, that it is so arranged and constructed, as to -compel the gases and liquids to change their direction of movement various times and on the other hand` by filling the chamber with bodies ,of the kind hereinafter' described, both a very great surface action as well as a great permeating action of the gases and liquids is produced in conse uenceA of the very-fine disintegration of the 'quid and its permeation by the ascending gases, aided by the fact, that the gases by impinging against the opposin lower surfaces are brought into contact wi the inclined surfaces of the lowerlayer of llin bodies not only once as usually, but. severa times. rlhe depositing of flue dust is moreover avoided in the lling bodies forming the subject of this invention in a far better manner than 'in the previous filling bodies.l

0f the accompanying drawings which illustrate a preferred form of construction of my invention:-Figure l is an end view of .the body block or brick. Fig. 2 is a side vieur of the body block or brick. Fig. 3 is a perspective view of a number of the body blocks ,or bricks built up to illustrate, by way of ex ample, the mode of usingthe same for filling a reaction chamber.

In the drawings, the body block or brick is shown as having end faces-a,.inclined side faces a narrow Vupper lane surface t and a broa 4base c. The sai( base is hallowed out as shown at d so that theblock is guttern shapedin cross section.' The sides jf; othe Specicaton of Letters atent. application and June 25, iena. semi No. ascesi.

body block or brick are shown as grooved er fluted as at g.

The filling block or body is made in foam of a prism with side faces f inclined so as to constitute a kind of roof, while the base part cof the body is constructed in such a manner, that thev bodies of this kind may be built up layers constituting gratos, like ordinary bricks. ln its most simple form the said body constitutes a four sided prisir, two sides of which are parallel, and of tl'iese the side b which corresponds to the acute angle formed by the two inclined surfaces, is very narrow, while the opposite Lrface c, which forms acute angles on both sides with the inclined surfaces, is made comparatively broad. inasmuch as thc said body, as distinguished from the filling bodies of polygonal sectional shape and providedv with enlarged heads or with'special supporting studs,

, or the like, is supported directly by one of its lparallel sides, the said parallel surfaces must e made of such shape and of such size, as to allow of the direct su )porting of the said bodies. The liquid, which is caused to run upon filling bodies of this kind is partly made to rebound, provided it is delivered upon the broad inclined surface, being thereby finely disintegrated, or partly the liquid distributed over the surface of the inclined sides, 'which is aided by the diamond shaped series of grooves g on the surface, shown in the form of construction represented as an examle on the drawing. ',lhe gas which ascends om below is reiiected from the broader one of the two parallel surfaces, in case this surface 'forms the base of the filling body, the gas being thereby violently whirled around and being thereby compelled on the one hand, to move through a longer path than usually through the particular reaction space, beingrthereby brought in contact with one and the same contacting surface several times and on the other hand by this means an intimate permeation and mixing with the finely divided sprayof liquid is produced and the rebounding jets are also thrown against the inclined surfaces of thelowerlayer of bodies, where the gas may act upon the liquid, that covers the said inclined surfaces. When, on the other hand, the broader one of the two parallel surfaces is on top, so that the inclination is tapering downwards, the gas impinges against the inclined surfaces, where it is reflected, While the liquid, which runs down from above, drops oil partly at the edge of the broader one ofthe parallel surfaces, another part of the liquid iiowing over the inclined surface in this arrangement also in view of the diamond shaped arrangement of grooves and in consequence of adhesion, so that in this case also the gas acts upon the liquid both by permeation as well as by means of surface action. By the throwing to and fro of the gases and ofthe liquid, wh'ch takes place in these two arrangements of t ie'lling bodies, the path of the movement of the said agents is considerably increased and they vare prevented from passing directly throuvh the said space, so as to effect a convsidera le increase of the reaction. Between .the several bodies a gradually extending space is produced, in which the'gas is free to expand and is able to eilect its cliemical and ot er reactions as completely as possible. In view of the liquid running down the inclined faces under all conditions, the flue dust, in case such deposits should occur, is washed down easily. When the bodies are arranged with the inclined surfaces tapering upwards, the fine dust will moreover be thrown eil.' from the broad base and is rejected downwards and loosened, so that it is prevented from collecting at any places, while when one ofthe parallel surfaces is on top, the flue dust impinges against the inclined surfaces, from which it is reflected, and part of it will slide down on the inclination, without any possibility of remaining deposited in any place.

In the form-of construction, shown by way of example on the drawing, the broad, parallel surface'c is conaved, so as to constitute a longitudinal groeve d, which groove, in the case of the broad base being arranged at the bottom, also contributes greatly to the rcbounding of the gases and of the iiue dust, while when the said broad surface is on top, the said concave part orgroeve acts as an overflow.

The rhomboidal or diamond sha ed fluting of the inclined sides prevents t 1e liquid delivered upon the body from above, and which has not yet been disintegrated, from runnin down at one point or a few )oints only o the inclined faces, when the road base part is at the bottom, and `it also accomplishes the result of s reading the li uid on the entire extent o' the surface. `vlflhenthe broad base is on top, the rhomboidal iluting of the surface prevents` the ripping down of great masses of the liquid at the straight edges, a considerable portion of the li uid being spread on the contrary over the inclined surface.

It is of course permissible to arrange the filling bodies of one 'and the same layer alternately with the broad base on top and at the bottom or the iilling bodies of one layer /Inay be arranged with the broad base downwards, while in the next succeeding layer the base of the bodies is upwards. The incisions also. rfhe particular space may be ii lcd with these -filling bodies in any desired manner, the interstices between the bodies being either large or narrow and small. the filling bodies shouldbreak, the entire filling remains stable nevertheless and there is no fear of obstructions of the iilling by bricks or pieces of the saine drop ing down, as it is the case for instance wit i the polye angular filling bodies, provided with lateral projections, heads or studs. The inclina tion of the inclined surfaces of the filling bodies in relation to each other is preferably arranged in such a manner, that these surfaces will be struck even by gases, passing through the chamber at a comparatively7 ree duced ressure. This inclination has een found )y experiments to correspond substantially to the angle, formed by the outer faces of a jet of gas, issuing under low res- If any of sure from a slot inno the outer atmos` iere.

l do not wish' to claim packing bo ies of trapezoidal cross section broadly, such packiiuting of the sides, the liquid in the former bodies being splashed upon the surface in a thick stream, instead of covering it as a thin and uniform iihn and there was not that possibility of the rebounding and throwing to and fro of the ascending gases which is accomplished by the ineurved base, the shape of which also contributes to the stability of the packing and increases the acting surface, as com )ared with a 'flat base.
