Abstract: A method and device for producing metal foils using the foil-casting principle includes the steps of filling a casting frame with liquid metal, moving a substrate through the bottom of the casting frame, with the substrate belt being at a lower temperature than the melting point of the liquid metal in the bottom of the casting frame, so that a bottom layer of the liquid metal crystallizes on the substrate and a metal foil is formed on the substrate on one side of the casting frame. The method further includes the steps of measuring at least one of a thickness and weight of the metal foil, and adjusting the contact surface area between the liquid metal and the substrate as a function of the measured value for the thickness and/or weight of the foils produced.

Abstract: The invention relates to recovering a carrier for a synchronous demodulator, that receives an input signal. A carrier is reconstructed for the provided input signal, and the input signal (in) and carrier (tr) are mixed to generate a mixed signal to be outputted (i, q), wherein a residual phase error of the mixed signal is corrected by a phase shift to provide a phase corrected output signal.

Abstract: The invention relates to a method as well as a circuit arrangement for suppression of a perturbing quadrature component of a carrier signal of an amplitude-modulated signal during the recovery of the carrier signal in a synchronous demodulator, which outputs a quadrature signal (Q). The perturbing quadrature component of the carrier signal is estimated and the estimated quadrature component is subtracted from the quadrature signal (Q).

Abstract: A method and a device for producing thin layers from liquids to form coatings or foils. A substrate and a liquid application point are moved relative to each other and during the movement the liquid is applied at the application point onto the substrate, while forming a liquid strip, in an amount which is greater than is necessary for the formation of the liquid strip. The excess liquid is guided from the application point to the removal point against the outlet direction and the formed liquid strip is allowed to solidify.
