摘要： An electrolysis cell (10) for producing a molten metal having a density less than a density of a molten electrolyte used for producing the metal in the cell. The cell includes a section (14) for the electrolysis of a salt of the the metal contained in a molten electrolyte to form droplets of the metal in molten form contained in the electroylte; electrodes (18) within the electrolysis section for effecting the electrolysis; a metal recovery section (15) for separation of the metal from the electrolyte to form a molten metal layer, having an upper suface, floating on an upper surface of the molten electrolyte; a tapping device for periodically removing molten metal from the cell; and a reservoir (25) for withdrawal and temporary holding of molten metal separated from the electrolyte in the metal recovery section. The reservoir has a means to remove liquid from the reservoir without permanently removing the liquid from the cell. The reservoir has a top, sides and bottom and has one or more openings in the top or sides of the container communicating with the metal recovery section. At least part of the opening(s) is maintained below the upper surface (71) of the metal layer during at least part of normal cell operations, and all of the opening(s) is kept above the upper surface of the electrolyte in the metal recovery section for at least part of the normal cell operation. The sides and bottom are otherwise closed to prevent metal or electrolyte from freely flowing between the metal recovery section and the reservoir. The cell containing such a reservoir may accommodate high rates of metal production without unduly increasing cell size or requiring high heating requirements.

摘要： A photoacoustic gas analyzer comprising a measuring chamber, a modulated light source, and at least one microphone in connection with the measuring chamber and measuring the changes of pressure caused by the absorption of the light in the chamber. The measuring chamber comprises an inner surface with a reflecting coating. The measuring signal is thereby proportional to the gas concentration and is not provided as the difference between two almost equal values. As a result it is possible to measure small gas concentrations provided the light intensity within the measuring chamber suffices.

摘要： Paramagnetic gas analyzer comprising an electromagnet with an almost closed ferromagnetic circuit and a gap, including a measuring chamber with inlet and outlet lines for the gas to be analyzed as well as a gas of known magnetic susceptibility where devices are provided which measure the differential gas pressures in the respective lines by supplying an AC current to the electromagnetic. According to the present invention it is shown, how the power consumption can be considerably reduced. This object is achieved by superimposing a DC magnetic field generated by means of a permanent magnet onto the AC magnetic field. The amplitude of the measuring result depends on the product of the AC field and the DC field. If the DC field is strong enough, the AC field and thus the supplied power can be reduced accordingly. The latter also facilitates the filtering off of predetermined, undesirable signals.

摘要： The method is provided for operating a pump unit with a centrifugal pump which is driven by an electric motor and which comprises a rotor running in a split tube. The rotor space is separated with respect to the stator in a fluid-tight manner. On running the motor to its operational rotational speed the fluid located in the rotor space due to the increasing rotational speed evaporates and is removed so that the motor finally functions as a dry-runner.
