    Abstract: The invention relates to a method for recovering the metal values from materials containing at least one of zinc and tin, by smelting the starting materials under oxidizing conditions and reducing the resultant molten bath. The starting materials are first smelted in a furnace while adding flux, to form a slag which is sluggish at selected reduction temperatures and has a low lead contents. The reduction process is carried out while charging solid carbonaceous reduction agent and optionally also sulphur- and/or chlorine-donor material to the slag. The reduction agent and optionally supplied donor material is brought into suspension with the slag, and this suspension is sustained at least during the latter phase of the reduction period, at which the lead content of the slag has fallen to beneath about 1-2%, during which phase the reduction of zinc and tin takes place. Zinc is recovered from the furnace in the form of zinc vapor, while tin optionally is removed as volatile tin sulphide, chloride or oxide, and lead and any other metal values present in the starting materials are recovered as a molten lead phase.

    Abstract: A cable termination device of the dry type, including an insulator housing with an upper end and a lower end and having a hollow interior, which lower end has an opening for insertion of the cable. The device further includes a stress controller device located inside the insulator housing and adapted to be mounted on a high voltage cable, and an electrically insulating gel filling at least part of the hollow interior of the insulator housing and surrounding at least part of the stress controller device. Further, the stress controller device extends from the lower end of the insulator housing and into the housing where it has a free end, whereby a space is formed between the stress controller device and an inner wall of the insulator housing.

    Abstract: For trowelling concrete spread over a floor, a trowelling device is used, which includes a carrier having a cantilever arm swingable over the floor. At the distal end of the arm a rotatable trowelling member is carried in a pedestal structure permitting vertical adjustment of the floor contacting parts. A laser sends a horizontal beam at a predetermined level over the floor, and an upwardly directed measuring rod at the housing of the trowelling member is provided with a detector for catching the beam, and for transferring deviations of the beam from a mark thereon into signals for adjusting the position of the trowelling member.
