Abstract: ABSTRACT OF THE DISCLOSURE      An oxygen conductive solid electrolyte plate has first and second opposite surfaces.  First and second electrodes fixedly extend on the first and second surfaces of the electrolyte plate respectively.  A spacing frame hermetically secured to the first surface of the electrolyte plate surrounds the first electrode.  The spacing frame has an opening.  A sealing plate hermetically secured to the spacing frame defines a chamber in conjunction with the electrolyte plate and the spacing frame.  The chamber accommodates the first electrode and opens into an environment only via a window defined by the opening in the spacing frame.  The window allows oxygen molecules to flow from the environment into the chamber by diffusion.

Abstract: In previous composite building slabs for sectional false floors, which are supported at their four corners and consist of an upwardly open trough produced from tension-proof material and of a filling of compression-proof material, e.g. anhydrite, a greater deflection is produced, under load, at the edge of the slab than in the centre of the slab, which is undesirable. In order substantially to even out the load-bearing capacity and security of composite building slabs of the above type against breaking at the edge of and in the centre of the slab, provision is made on the side walls (6g) of the trough (3g) for a reinforcement which is virtually at the height of the slab and is non-positively connected to the base (5) of the trough. In addition or alternatively to this, it is also possible to increase at least twofold the density and strength of the filling (2) in the edge region of the composite building slab (10g) relative to the remaining region towards the centre of the slab.

Abstract: A method and a plant for recovery of oil floating on water. The plant comprises a closed container (1), either submersible or semi-submersible, floating in the sea with its upper edge (5) at the boundary between oil and water. The mixture of oil and water floating on top of the container flows down through holes (10) in the upper surface or collecting table (4) of the container into the interior of the container. The mixture is then separated by settling and surplus water is discharged. A so called "calm bay" is formed above and in the immediate vicinity of the container by a collar (9) reaching above the surface and attached to the container, in order to gather the oil to a thick layer, so that less water flows down into the container. After settling, the oil is pumped over to a tanker. The container can be equipped with heating coils (13) in order to facilitate settling and enable pumping of the oil. A number of such containers can be combined to form a vessel.
