Abstract: The invention concerns a medium frequency transformer with a housing, in which numerous winding chambers, having primary and secondary windings, are disposed, wherein the housing is filled, at least partially, with an insulating liquid. The transformer is distinguished in that numerous winding chambers, filled with the insulating liquid, are disposed in the housing, and at least one winding is disposed in each winding chamber, such that, for the most part, only the windings are surrounded by the insulating medium. Preferably the winding chambers are sealed and separated from one another by means of insulating separating walls, wherein the windings are positioned and fixed in place in the winding chambers, and the winding chambers are filled with the insulating liquid. Between the windings there are thus, according to the invention, at least two insulating barriers, which function simultaneously and consist of solid matter insulation in the form of housing and separating walls, and the insulating liquid.

Abstract: A process for producing cellulosic shaped objects includes extruding and coagulating a solution of chemical wood pulp in a tertiary amine oxide, and possibly a liquid that does not dissolve wood pulp and is miscible with the tertiary amine oxide, the solution capable of being shaped into objects, the process of producing the shapeable solution employing a first wood pulp with a higher degree of polymerization and a second wood pulp with a lower degree of polymerization, and whereby initially a solution of the first wood pulp with a higher degree of polymerization in the tertiary amine oxide and possibly non-dissolving liquid, and a composition containing the second wood pulp with a lower degree of polymerization, tertiary amine oxide, and possibly non-dissolving liquid, are prepared separately, and the solution and composition are subsequently at least mixed to obtain the shapeable solution.

Abstract: The invention is a converter-fed drive system having at least one drive motor fed by a converter unit. The converter unit has a valve assembly containing semiconductor valves, a cooler for cooling the semiconductor valves and a capacitor assembly are mounted directly on the drive motor. There is also an inductor assembly, that is electrically connected to the converter unit, but is installed such that it is spatially separated from the converter unit and the drive motor. The cooler is simultaneously used to cool the drive motor as well as the converter unit.

Abstract: A process for fixing wear-resistant armoring tiles to cement mortar. In accordance with the process, the back sides of the tiles are coated with a mixture of polyester epoxy resin composition including sand and quartz or sand powder, with a curing agent. A material having an affinity for the cement mortar (like quartz sand or lavalite) is dusted and rolled into the coated back side of the tiles, so as to thoroughly be mixed up with the resin mixture coating. After the hardening of the coating including the material having affinity to cement mortar, the tiles are embedded in the cement mortar. Accordingly, this process substantially eliminates the well known poor adhesive properties of such tiles with respect to cement mortar.

Abstract: The present invention concerns a contact arrangement with a first contact and a second contact. The second contact has two contact members between which the first contact is received. A contact support resiliently supports one of the first and second contacts so that the supported contact is resiliently mounted relative to the contact support means and movable relative to the other contact.

Abstract: An apparatus and a method for producing dry, compressed air to be used for electrical switchgear, especially for high-tension switchgear, is disclosed in which humidity is extracted from the air in a subsequently arranged sorption dryer, with one portion of the dried air being used to regenerate a drying agent of the drying apparatus. The drying apparatus includes a cylindrical inner housing which is used for the pre-drying of the air, an outer housing which surrounds the former in jacket form for the final drying and a desorption volume. An electric heating rod protrudes concentrically into the inner housing and is covered by either a baffle device or a pipe so that a ring-gap is created between two components, with the ring-gap divided into two halves. The air is pre-dried in the first drying chamber prior to its entry into the compressor, with the temperature of the air being kept above the dew point during compression and cooling.
