Abstract: ABSTRACT     In an electrolytic reduction cell for the production of a molten metal by electrolysis of a molten electrolyte, the product metal collects on a cathodic carbon floor having embedded steel current collector bars for leading out the cathodic current.  In order to reduce the wave motion of the metal due to interaction of horizontal currents in the product metal with the magnetic fields due to currents in conductors associated with the cell, electrically non-conductive barrier members are arranged on the floor of the cell transversely of horizontal currents in the product metal.  Such barrier members have at least a surface layer of material resistant to product metal and extend upwardly from the cell floor to a height approximating to the normal maximum operating level of product metal.

Abstract: ABSTRACT OF THE DISCLOSURE           A reclining platform for bathtub units has a rectangular-shaped reclining platform and four hinged plates joined to the side edges of said reclining platform by means of hinges.  The hinges are equipped with springs that press the hinged plates into the same plane as the base plate.  The hinged plates can pivot upwards against the tension of the built-in springs.  The entire reclining platform has a mat 44, which forms wedges at the corner recesses between each pair of hinged plates.  The mat is made of a flexible material. The reclining platform covers the entire length of the bathtub, without folds, when the unit is in raised position.  When the unit is lowered, the hinged plates abut tight-ly against the tub  walls, and the wedges are folded up and close off the rounded corners of the walls.  The unit ensures that handicapped persons cannot get trapped.

Abstract: Abstract:    In the present invention, a steam converter for use in particular in connection with the mechanical preparation of pulp by means of grinders is described, which steam converter comprises two separate water spaces, on which one space includes an electrical boiler and the other space is in connection with a heat transfer face on the other side of which the contaminated steam coming from the pulp preparation process is condensed.  These water spaces are interconnected by a valve, through which water can be moved into the electrical boiler either by the effect of gravitation or by means of a pump.  Out of the electrical boiler, water can be passed into a pressure-free water storage tank by means of a second valve.  These valves are controlled in accordance with varying loads of the grinders so that, by controlling the water level in the electrical boiler, the total evaporation output of the grinders and of the electrodes can be kept at a desired level.
