Abstract: A method for detecting the state of electrical connection of an energy store, e.g., a battery, to a vehicle's electrical system includes ascertaining operating variables, e.g., battery current IB and generator current IG, essentially in time synchronous fashion. When there is a change in the generator current IG of the generator during a transitional time, the energy store is checked for the value of the battery current IB for the detection of a compensating effect in the form of a current delivery or a current consumption.

Abstract: An apparatus for reducing procession of a gapless tubular printing blanket in an offset printing press caused by at least one fluid wave having a certain pressure trapped at an interface of the printing blanket and a blanket cylinder. The apparatus includes a blanket cylinder which is adapted to receive the printing blanket for mounting on its circumferential surface. The blanket cylinder has at least one path which connects an interface of the blanket cylinder and the printing blanket to a region of pressure lower than the pressure in the fluid wave. The path allows the fluid wave, which is trapped at the interface and advancing in front of a nip between the blanket cylinder and an adjacent cylinder, to escape to the region of low pressure.
