Abstract: A device (101) for data-reception using amplitude modulation, comprises a coil (121) having a coil terminal (123) and being adapted to receive an amplitude modulated electromagnetic wave (116), whereupon an amplitude modulated signal (Vb) is induced in the coil (121) and provided at the coil terminal (123), the amplitude modulated signal (Vb) comprising a positive voltage portion (325, 427) and a negative voltage portion (324,428); and an adjustment circuit (125, 300,400) connected via an input terminal (129, 302,403) to the coil terminal (123), wherein the adjustment circuit is adapted: to adjust the amplitude modulated signal such as to reduce the positive voltage portion (325,427) by a constant amount (?) and to provide the adjusted amplitude modulated signal (129, 323,425) at an output terminal (131,317,427) of the adjustment circuit (125, 300,400).

Abstract: An apparatus for coating substrates with a coating material is disclosed. The apparatus includes a frame and a crucible arrangement including a first crucible and a second crucible disposed on the frame. Only one first shaft is associated with the first crucible and only one second shaft is associated with the second crucible, where the only one first and second shafts are disposed in the frame beneath the first and second crucibles, respectively. Only one first lifting device is associated with the only one first shaft and only one second lifting device is associated with the only one second shaft, where the only one first and second lifting devices are disposed in the frame. The only one first and second shafts and the only one first and second lifting devices are laterally displaceable with the frame.

Abstract: The invention relates to an apparatus and a method for heating a workpiece of an inductively heatable material, for example a turbine blade. Such a turbine blade consists of a massive blade base and a low-mass blade leaf. To enable the blade base and blade leaf to be heated in a manner appropriate to each an induction coil is provided, which surrounds the blade base and the blade leaf. By suitable choice of the alternating currents which flow through the induction coil and/or through the interposition of a susceptor between turbine blade and induction coil, the blade base and blade leaf can be heated in an appropriate manner.

Abstract: A furnace roller for transporting of a continuously cast stock of a continuously casting plant through a temperature equalizing and heating furnace and including a rotatable arbor supported outside of the furnace and having cooling medium channels provided in its interior, a plurality of tires supported on the arbor and forming a transporting plane for the transported stock, at least one clamping ring provided between a tire and the arbor and formed of metal or alloy having a maximum possible thermal conductivity and susceptible to both cold and hot deformation, and at least one steel sleeve provided sidewise of the clamping ring.

Abstract: A water-coolable furnace roller for conveying goods to be transported through a roller hearth heating furnace has a shaft supported external to the furnace and driven in rotation. The shaft has an outer contact surface. Support rings having a receiving bore, respectively, are arranged with the receiving bore on the shaft, wherein the support rings form a conveying plane. The receiving bore has an inner contact surface, and at least one of the inner and the outer contact surfaces has a shape of a polygon contour of substantially constant diameter with fitting surfaces defining an orbiform curve.

Abstract: A laser operation such as a laser welding operation or a laser cutting operation is improved in its quality and a consistently high quality is achieved by arranging auxiliary tool units upstream and/or downstream of a main laser tool unit including a primary laser head on a common tool carrier. The secondary tool units upstream of the laser operation are intended for a preliminary surface treatment to present the most appropriate surface conditions for the following laser operation. Similarly, the tool units arranged downstream of the laser operation are intended for subsequent work operations such as an immediate cleaning operation, a coating operation or the like to avoid a reoxidation of the welding seam or of the cut edge of the work piece. The secondary tools make sure that the laser operation is enhanced or improved either by presenting optimal conditions for the laser operation or by improving the work piece subsequent to the laser operation.
