Abstract: The present invention concerns a beam for scaffolding or the like, which beam consists of a tube 1 with securing arrangements 2, 3 at both ends. The beam is intended to be secured in vertical spars. The tube forming the beam has been shaped at both ends over a tool so as to give a tear-drop cross section. This shaping of the tube ends gives the beam a torque-absorbing stiffening at each securing area, which means that greater loads can be taken up than would be the case if the tube ends were not shaped (Fig. 2). <IMAGE>

Abstract: The gases containing hydrogen chloride and sulphur dioxide are scrubbed in a first stage with an aqueous acidic scrubbing solution to absorb hydrogen chloride and in a second stage with an aqueous alkaline water solution to absorb sulphur dioxide. A part-stream (42) is taken off from the acidic scrubbing solution in a first stage and is regenerated in a secondary circuit (43) by neutralisation (44, 45), separating off heavy metals (46-49) and evaporation (50) to separate off sodium chloride (53). In addition, a part-stream (66) is taken off from the alkaline scrubbing solution in the second stage and regenerated in a secondary circuit (67) by addition of lime (69) for separating off gypsum (71) and addition of soda (73) for separating off excess calcium. The invention is primarily distinguished by the scrubbing solution in the first stage being kept essentially separate from the scrubbing solution in the second stage, the condensate from the evaporation (50) in the secondary circuit (43) of the first stage being returned back to the primary circuit (38) of the first stage and by a so-called indirect lime method being used for the regeneration of the scrubbing solution in the secondary circuit (67) of the second stage. <IMAGE>

Abstract: A floor underlay is completely or partly provided with a fibre material on the surface facing upwards. The fibre material is formed of a needle-loom or another material that contains long fibres that are oriented in different directions alongside the level of the surface of the material. The surface material of the floor is wholly or partly provided with fibre flock on the underside. When these materials are used when floor laying a secure fixation of the surface material to the underlay is achieved due to that the projecting fibres are fixed by the long, mainly alongside the surface running fibres of the underlay. Alternatively, the fibre flock and the underlay material can change places, whereby the same effect is reached. A tool to facilitate the laying includes a handle part, organs to grip the underlay material, organs to bear on to a piece of the floor surface material and with the handle part used as a lever move this part of the floor surface material away from the part of the underlay material that has been gripped.

Abstract: The mechanism holds the sheet material (31) inside a cold forming press during moulding, during which some parts of the material move as it is pressed against a die by hydraulic pressure applied via an elastic membrane (4) on one side of the material. A first device (18) is used to generate a hydraulic pressure for holding the material in place and a cylinder arrangement (15,16,17a) transmits this pressure to a piston (14) and also maintains the pressure. The piston is designed to urge a part of the material against a retainer (13) while the hydraulic pressure is maintained. A valve (20) is also provided which is directly affected by the moulding pressure and reduces the pressure applied to the material to hold it in place once the moulding pressure reaches a pre-determined level.
