Abstract: A steam separator including a tube which houses a blade arrangement consisting of a set of curved blades serving to rotate a mixture of steam and water in order to cause the water to form a film on the inside of the tube. The tube wall has a plurality of perforations through which the water can escape while the steam leaves through a special outlet tube. The individual blade of the blade arrangement has an axial extension at least twice as large as the largest width of the blade, as well as a curvature at least so pronounced that a trailing edge of an optional blade is angularly offset past an imaginary radial plane in the axial extension of a leading edge of an adjacent blade. The total area of the perforations amounts to 50-65% of the cross-sectional area of the separator tube.

Abstract: Power sources for welding applications and the like are provided in accordance with the teachings of the present invention. An inverter arrangement comprising a plurality of inverters, having inputs connected in series, receive portions of a d.c. load from a plurality of series connected smoothing capacitors. The smoothing capacitors are connected to form a voltage divider and apply the resulting portions of the d.c. load to the plurality of inverters. This enables the plurality of inverters to be dimensioned in a manner so as to withstand the smaller portions of the d.c. load resulting from the voltage division.
