Abstract: A method for safeguarding against the entry of foreign bodies into a nip between two cylinders, which includes applying a deflection movement to one of the cylinders counter to a spring force applied thereto so as to overcome the spring force and, in accordance with a prescribed deflection distance, alternatively keeping the spring force to be overcome constant or reducing the spring force; and a device for performing the method.

Abstract: A web-fed rotary printing press having a main drive includes, in combination, a plurality of consecutively arranged printing units and a printing unit for flying printing-form exchange having an auxiliary drive and a plurality of printing-unit cylinders, at least one of which has a shaft, the plurality of printing-unit cylinders including two printing-form cylinder-transfer cylinder pairs for the printing-form exchange, and a common, rotating impression cylinder driven via the main drive, one of the cylinder pairs being inactivatable and the other being bringable into engagement with the common, rotating impression cylinder so as to be driven by the main drive, two gearwheels positioned on the shaft of the one cylinder of the printing unit for the flying printing-form exchange, including a drive for the respective printing-form cylinder-transfer cylinder pair which is decouplable from the main drive, during an imprinting operation, and connectable via a coupling device with the auxiliary drive, includes an ar

Abstract: Non-linearities in phase detector output signals are digitally corrected as a function not only of the measured phase difference signal itself but also of the input signal amplitude(s) to the phase detector so that a desired degree of precision can be efficiently and conveniently maintained over the entire dynamic measurement range. Pre-stored digitized compensated output signals (or correction coefficients) are selected from a digital memory as a function of both the distorted phase measurement signal itself and the amplitude(s) of the signals being compared.
