The present invention relates to a method and an apparatus for imprinting a booklet-like object in a printing station.In order to develop a method and apparatus of the above type while reducing method steps and simplifying a structure of a corresponding apparatus, it is proposed that a booklet-like object (2) is inserted in an opened state into a drawer (3) and fed to a printing mechanism of a standard printer and is covered with a printing mask (6) and pressed into a new defined printing plane, wherein the new printing plane is created using a spacer element (5).

A circuit breaker and/or earthing switch are disclosed wherein a rotatable spindle nut, which is mounted in a spindle housing, displaces a spindle in a translatory manner, thus displacing contact elements of the switching device. The spindle actuates a contact pin that is configured in a contact carrier by a connection yoke that is common to all phases or poles and an isolating bar for each phase or pole.

A gas-insulated switchgear assembly (1) or component of a gas-insulated switchgear assembly is proposed which has an outdoor bushing (6) through which at least one high voltage-carrying conductor (7) is passed. A surge arrester (8) is arranged essentially parallel to the outdoor bushing (6) and is connected to the high voltage-carrying conductor (7) and/or to the top part of the outdoor bushing (6) via a high voltage-side connection piece (9) and to the foot part of the outdoor bushing (6) and/or to the housing of the gas-insulated switchgear assembly or the component of the gas-insulated switchgear assembly via a housing-side connection piece (10).

To minimize the overall circuitry necessary in a multiband-frequency generator, output terminals of a voltage-controlled multiband oscillator (22-1, . . . , 22-N) are coupled to a frequency synthesis unit (10) via a frequency selective coupling unit (24). The frequency synthesis unit (10) derives a phase difference between a frequency control input signal and the output signal of the frequency selective coupling unit (24) to control the voltage-controlled multiband oscillator (22-1, . . . , 22-N).

To avoid any dead time when switching between different frequency bands it is proposed to set a programmable multiband frequency synthesizer unit (12) adapted to generate an output signal in at least two frequency bands into a sleep mode before switching to a new frequency band, then to program the programmable multiband frequency synthesizer unit (12) according to the new frequency band, and finally to activate the programmable multiband frequency synthesizer unit (12) for operation in the new frequency band.
摘要:
The invention relates to a process for treating metal surfaces, preferably of aluminum, aluminum alloys and steel, for the subsequent application of organic coating compositions. The metal surfaces are wetted with an aqueous bath solution containing chromium(III)ions, fluoride ions and an organic film former which is soluble or homogeneously dispersible in water, after which the solution applied is dried and converted by heating into a water-insoluble film.The bath solution preferably contains the following constituents and approximate quantities thereof: 0.5 to 10 g/l of chromium(III)ions, 0.55 to 11 g/l of fluoride ions, 0.6 to 12.5 g/l of phosphate ions, and 0.15 to 5.0 g/l of organic film former. The organic film former preferably used is a polymer containing free carboxyl groups, more preferably a homopolymer and/or copolymer of acrylic and/or methacrylic acid.
