Abstract: The invention constitutes a method during underwater explosion welding, on the sea bed for example, for removing the water between the material elements (2, 3) which are undergoing the explosion welding, and represents a considerable simplification compared with known conventional systems. Hereby, the problem with sealants, pumping units and other equipment disappears.Air, or another suitable gas, is conveyed to a column space (5) between the material pieces (2, 3) in a short time frame and immediately before the welding operation for the removal of any water present in the column space.The requisite pressure pulse of air or gas can be conveyed from a pressure tank attached to the column space (5).The pressure pulse can also be maintained in a pyrotechnical way, either by gas development in the seam space itself, or in a container especially attached for this purpose.<IMAGE>

Abstract: The appts. consists of a rod (1) which at one end is provided with two angularly positioned plates (2, 3). A ring (4) is rotatably fixed to a joint (5), and also incorporated are a torsion spring (6), a collecting bag (7), an operating line (8), and a stop component (9). The rod with the sampling appts. is inserted in the fluid with the ring pressed against the one plate (2) with the aid of stop hooks (9), and against the force from springs. When the samping depth is reached, the stop hooks are released with the aid of the operating line (8). At that moment, force from the torsion springs pushes the ring in a circular movement to locate against the other plate (3). In the ring is held open an opening for the collecting bag, and the bag in its starting position is folded together so that it is contained within the ring. When the stop hooks (9) are released and the ring describes its circular movement, the bag unfolds and collects surrounding fluid on its way upwards. When the ring reaches the second of the two plates, the bag is closed, and the whole appts. can be raided with the fluid sample intact.

Abstract: A method and a device for producing hydrochloric acid by contacting a hydrochloric-acid-containing gas with an aqueous washing liquid are disclosed. A chloride-forming substance is added to the washing liquid, so that the hydrochloric acid in the gas not only is bound by the chloride-forming substance as a chloride salt, but also is absorbed by the washing liquid as 'free' hydrochloric acid. Optionally, the washing liquid is then concentrated by stripping of water. Subsequently, sulphuric acid is added to the washing liquid to drive off hydrochloric acid from the chloride salt. Finally, hydrochloric acid is distilled from the washing liquid. The device includes a scrubber (1) having inlets (2, 10, 11, 12) and outlets (5, 13), a distillation unit (25) having inlets (27, 24) and an outlet (29), and optionally an evaporation unit (14) having an inlet (16) communicating with the scrubber outlet (13), and an outlet (24) communicating with the distillation-unit inlet.

Abstract: A method and a device during start and stop or other partial-load operation of a once-through boiler, for example a PFBC boiler, for maximizing the steam production to superheaters (SH1, SH2) and any reheaters (RH) in order thus to ensure optimum cooling of the tube surfaces immersed into the fluidized bed under these conditions. This is achieved by separating the superheaters (SH, RH) from the components located ahead of them in the steam cycle of the plant, such that the pressure in the two steam system circuits thus separated can be reduced according to the internal requirements which apply to the respective steam system circuit. The two steam system circuits are separated with respect to pressure between a first moisture separator (SEP), which is arranged downstream of the steam generator (EVA) of the power plan, and the subsequently located superheater (SH1). The pressure separation is realized by means of a cut-off valve (V4).

Abstract: Instead of blending cement, water, sand and other flow additives at the same time in the usual way, cement, compound and flow additive is thoroughly blended, and not until after that sand and water are blended in. The compound is comprised of silica and/or another material which can prevent the water from reaching the cement until after the casting. The compound is added in such a large amount that it can coat the cement particles and further fill out the voids in the concrete. Thereby the water binding number, vbt, can be reduced to about one half so that the packing is more dense and the structure of the concrete becomes similar to ceramics. The method according to the invention can be practised with mainly the usual machinery in cement factories without any substantial investments or other costs.

Abstract: This invention belong to a mounting technology for aligning parts, a self-aligned elastic positioning. A problem this invention solves is alignment of parts without using mechanical fine pre-alignment. Wherein one part has elastic bumps, another part has V-grooves and the parts fit into each other. The invention is using elastic material for the bumps to fit the V-grooves. Whereas the bumps are made of elastic material and shaped partly to the V-bumps by moulding. The two parts can slide along in the direction perpendicular to the plane of the surface of the part. The movement in the perpendicular direction can be controlled by an external force. This means that the bumps and V-grooves have good alignment in xy-orientation and are also partial aligned in z-orientation. The elasticity of the bumps allows for thermal expansion differences without stresses to the parts while maintaining high precision alignment at a point. By using this type of parts they can be disassembled and be replaced without destroying the alignment features.
