  • Device and method for printing a wrapper strip
    Patent number: 8953217
    Abstract: An apparatus for printing a banding strip for documents of value, which is preferably moved relative to the apparatus, having a print head by means of which, upon an activation, more than nine dots can be printed, a circuit actuatable by print signals, which, in response to print signals, activates the print head in accordance with the print signals, in order to print patterns specified by the print signals, and a current supply unit for providing current for the circuit and by means thereof for the print head.
    Type: Grant

  • Amplifier comprising ECL logic gate biased by another ECL logic gate
    Patent number: 4533878
    Abstract: A circuit for amplifying electrical signals, particularly for devices for transmitting frequency-modulated emitter coupled logic (ECL) broad-band signals by means of coaxial lines utilizes a plurality of ECL logic elements as amplifier stages. The input of each logic element is connected to a bias voltage and is charged by means of a coupling capacitor with the signal to be amplified. The circuit amplifies electrical signals to ECL level with an improved signal pulse duty factor.
