Abstract: ABSTRACT OF THE DISCLOSURE          In a stabilized voltage source having an actual-value voltage gauge which is temperature dependent, the overall temperature stability of the voltage source is improved by providing a reference-value voltage with an adjustable temperature coef-ficient, said temperature coefficient being so adjusted that it substantially compensates for the temperature dependence of the actual-value voltage gauge within the temperature range used.  The reference voltage having an adjustable temperature coefficient is preferably obtained by combining a first voltage which is essentially independent of temperature with a second voltage being strongly dependent on temperature, the degree of mutual influence of said combined voltages being regulated to adjust said temperature coefficient.

Abstract: ABSTRACT OF THE DISCLOSURE          An air-choke coil having at least two concentric wind-ings, or winding parts, in which the windings, or winding parts, are crossed over.  Known similar coils are usually provided with a plurality of parallel, current-carrying wires forming the conductor.  The use of a plurality of conductors substantially reduces unwanted losses and heating produced by eddy currents and the like.  In such air-choke coils uniform distribution of the current to a plurality of parallel conductors is usually achieved by means of the so-called cross-over technique.  The air-choke coil according to the present invention is sub-stantially simpler in construction in that the windings, or winding parts, need not be wound simultaneously, as in the case of known similar constructions.  The coil comprises at least two concentric windings, or winding parts, in which the windings, or winding parts, are crossed.  A separate crossing piece is provided for the purpose of crossing the conductor cables.  In one embodiment the crossing piece is in the form of a flat web with a connecting piece at each end for connect-ing conductor cables thereto.

Abstract: ABSTRACT OF THE DISCLOSURE            A dosed amount of molding material is placed in a vessel arranged at a given distance from a pattern device from which a mold is to be formed, and a pressurized force is applied against the molding sand in the vessel from the side thereof remote from the pattern device in order thereby to impart to the molding sand an acceleration in the direction of the pattern device to compress the sand about the pattern device with the velocity of the accelerated molding sand being braked by impact with the pattern device and also by impact partially with a molding box within which the pattern device is contained.  The vessel containing the molding sand is connected to a pressure source by a valve device which controls the application of pressure to the molding sand. Additionally a vacuum device is utilized to apply suction tending to compact the sand within the vessel to produce a more cohesive mass.  After the vessel and the pattern device are moved into operative position, and the suction has been terminated, the valve may be opened to apply a pressurized force propelling the sand from the vessel against the pattern device.

Abstract: ABSTRACT OF THE DISCLOSURE A grooved roller, as used for the dewatering of paper webs, is fabricated by winding one or more metal strips in a continuous helical path upon an inner support roller.  Adjacent turns of the strips are interconnected as by spot welding, soldering or glueing.  The surface groove can be formed in various  ways as by machining during winding of the strip, or by using two strips of different heights.  Before winding the strip may have a slightly tapered cross-section so that after the winding deformation the sides of the wound strip are precisely parallel.
