Abstract: Provided are a method and to a wet scrubber for removing particles from gas. The wet scrubber includes a second vertical cylindrical vessel having a second upper end for receiving an accelerated stream of liquid- and particles-laden gas from a vertically oriented venturi channel and a second lower end for feeding the accelerated stream of liquid- and particles-laden gas to a swirl generator. The second vertical cylindrical vessel and the swirl generator are arranged in a vertical cylindrical separation space of a first vertical cylindrical vessel. The swirl generator is arranged above the liquid tank.

Abstract: An arrangement (1) for the electrical earthing of an electrically conducting cable (2) with an outer insulating protective cover (3). The arrangement comprises a receiver (4) and a drop unit (5). The receiver (4) comprises a bottom element (6), two opposing side elements (7a, 7b), two opposing open sides (8a, 8b). The bottom element (6) and the side elements (7a, 7b) form together a cleft (9), which cleft (9) is the receiver of the said cable (2) for earthing. The drop unit (5) comprises not only a connection to earth (10), but also a penetration means (11), which connection to earth (10) and penetration means (11) are in electrical contact with each other.

Abstract: Device for arranging cables in a junction box extractable from a chassis. Between the junction box (1) and the chassis (2) there is a conduit (5) into which the cables (7) are run from the front viewed from the direction in which the box is extracted from the chassis (2), whereby the length of the cable (7) in the chassis (2) is chosen so that the junction box (1) can be drawn out of the chassis (2) for a distance determined in advance.

Abstract: The invention relates to an insulator for an electrical conductor provided with an outer shield, especially a so-called coaxial cable or shielded twin cable, in order to achieve an insulation at the shield that insulates against DC and low frequency AC signals transforming through the conductor and that includes a first and a second element (3,4) formed from electrically conducting material that by means of a dielectric (5) are electrically insulated and delineated from one another. and that are intended to be connected between an interruption at the shield or between the shield and an external earth connection.

Abstract: The invention relates to an electrowinning cell for extracting metals in powder form from solutions, and simultaneously oxidizing the solution. The cell is characterized by radially extending electrodes comprising mutually alternating anodes and cathodes; by a diaphragm which delimits separate anode and cathode chambers, of which the cathode chamber forms an outer space; and a stirring means arranged in the anode chamber and operative to ensure a large flow of electrolyte across the anode surfaces. The base of the cathode chamber is preferably conical in shape.

Abstract: The invention relates to a method for selectively recovering lead from complex sulphidic non-ferrous metal concentrates in an electrolytic cell incorporating at least one anode and one cathode and an electrolyte containing chlorine ions, at a temperature beneath the boiling point of the concentrate-containing electrolyte and at a pH beneath 7. Sulphur present in the concentrate is converted substantially into elementary form, and at least the major part of the lead content passes into solution and is then precipitated selectively by cathodic processes. The invention is characterized in that the concentrate is slurried in an electrolyte having a chloride-ion strength above about 2 M, preferably in the range 3-5 M, to form a suspension which is caused to flow into contact with or adjacent the surface of anodes located in the cell; and in that the highest possible anodic current density considering required selectivity is maintained during the electro-winning process.
