Abstract: To fill up the ring-shaped gaps between the tubes and fins of a tube and fin type heat exchanger with a corrosion protective hardenable filler, a unit made up of two closing pieces with filler material between them is pushed by means of the tube to be inserted in the stacked fins through the space formed by the collars of the openings in the fins which are stacked together for assembly into a heat exchanger. On passing this unit through the stacked fins the ring-shaped gaps are filled up with the filler material. The remaining thin film on the collars is also forced into the ring-shaped gaps when the tubes are subsequently expanded. A device for carrying out the process comprises a sleeve with a mandrel which slides inside the sleeve and forms a seal with the sleeve and a piston which likewise slides in the sleeve and forms a seal therewith and which lies ahead of the mandrel forming a space which can be varied in size and which accommodates the filler material.

Abstract: A mixture which is used for the manufacture of electrodes and comprises dry material and electrode binding agent. The mixture is prepared in a system which is at least in part dust and gastight and such that the mixture is simultaneously stirred up or fluidized, degassed and homogenized, and treated thermally. In the course of such treatment further additions can be made to the mixture. The described procedure takes place mainly in mixers operating continuously or discontinuously, various arrangements and designs of mixer being possible.Fundamental to the thermal treatment is that the mixture can be cooled in a mixer such that the coolant vaporizes completely during the mixing.The thermal treatment is regulated by way of given operational parameters.

Abstract: The mold features on its work face a thermally insulating protective layer of sub-micron metal oxide particles.The coating can be applied by spraying an aqueous sol of a metal oxide onto the mold work face which has been heated to at least 60.degree. C.The use of sub-micron sized metal oxide particles enables the formation of a protective coating of very low density and consequently very low thermal conductivity. The coating can furthermore be deposited very economically, and likewise removed again.

Abstract: A container for transporting goods in the form of packages, bundles or the like having a floor, walls, roof and at least one door which can be locked, is improved such that it can be stored without problem, is spaced-saving when transported empty and light in weight, and allows individual parts to be readily replaced, while at the same time being economical to manufacture.The container has its floor and roof joined at a distance from each other by vertical corner posts to which stable, rigid sidewalls are also attached such that the corner posts are releasably joined to the floor and roof of the container by cube-like corner pieces. Instead of or in addition to the foregoing design, at least one of the walls feature at least one deep-drawn metal sheet or panel in which stiffening areas are provided, delimited by a peripheral region in the sheet and/or ribs extending from the edge regions.

Abstract: A device for supporting a moveable seat, for example a seat in a motor vehicle, by means of sliding rails which can be displaced in their longitudinal direction on roller facilities situated between the sliding rails and stationary alignment rails, the position of the seat being set by a mechanism which arrests the movement of the seat and involves, if desired, notches on at least one alignment rail, made such that it can withstand excessive loading, at the same time being simple and inexpensive to manufacture and install. This is achieved by having both the sliding rail and the related alignment rail feature at least one flange projecting out at the side, such that the flange on the sliding rail lies a short distance below the flange on the alignment rail resulting in flanges coming into contact under overload conditions. The facing flanges feature surface projections which interlock when under load.

Abstract: A lower part of a fused salt reduction cell used in the production of aluminum, comprises an electrolyte tank supported by metal beams. The tank is made up of an outer steel tank, a thermally insulating layer and an inner electrically conductive carbon lining which can withstand molten metal. A frame of steel sections arranged in a grid-like pattern in the longitudinal direction is made up of single, massive side sections and, spaced apart in keeping with strength requirements and cell design, so called cradles which enclose the side sections. The cradles are made up of pairs of solid side posts secured to lower supporting sections and upper bracing sections. The electrolyte tank is situated in the frame and fixed in place against the side sections via counteracting elements which can be deformed plastically or elastically.

Abstract: The anode effect which is necessary in the electrolytic cell can be extinguished after a short time if, immediately after it appears, fine granular salts are introduced together with an injection medium through a suitable channel into the electrolyte and under the anodes. These salts which are not harmful to the electrolytic process cause vigorous production of gases at the operating temperature of the cell. The channel for introducing the salts and the injection medium is usefully situated in the crust breaking chisel or a lance which can be lowered into the bath. The device comprises further a storage vessel for salts which has a closing facility which is activated via a closing piston, below that a combined measuring and injection chamber featuring an injection nozzle and a tube with by-pass connecting up to the injection chisel or lance.

Abstract: A chisel for a crust breaking facility for breaking through the solidified crust of electrolyte on an electrolytic cell, in particular a cell for producing aluminum, is such that at least a part of the edge region on the bottom face of the chisel projects out beyond the other regions and is in the form of cutting edges. The bottom face of the chisel features no faces which are inclined outwards and would create outward directed forces as the chisel is forced through the crust.The chisel of the invention allows energy and investment costs to be reduced.

Abstract: Processes for manufacturing a metal-plastic composite foil having a plastic core covered on both sides with an outer layer of thin metal strip, in particular aluminum thin strip, are already known. However, the use of a so-called triplex composite of the kind just mentioned for relatively large volume containers of full weight up to about 30 kg has been very limited because of the unsatisfactory deep drawing properties of such composites in deep drawing or deep drawing by elongation of the foil (stretching). By means of the invention a process for manufacturing a metal-plastic composite of the so-called triplex composite kind and a metal-plastic composite foil made by this said process have been developed which allow in particular the manufacture of semi-rigid light-weight containers which have a weight of up to about 30 kg when full and this even by cold forming.

Abstract: The invention relates to a process for the continuous manufacture of foamed sheets of thermoplastic material having an extreme width to thickness ratio, small thickness tolerance, a uniform cell structure and, over the whole cross section on both sides of the sheet a thin, non-foamed outer skin. The plastic, which already contains the foaming agent is, on emerging from a wide-slit nozzle, allowed to foam freely without any restriction and cool. The sheet or strip formed in this manner is then heated locally at the surface and calibrated to final dimension.
