Abstract: An escalator drive assembly (30) includes a sensor that facilitates detecting when the normal drive assembly operation is interrupted, such that a brake should be activated. In one example, a sensor member (40) in the form of a flange (42) is associated with a drive pulley (34) and normally rotates in unison with the drive pulley. When there is a failure in the normal operation of the drive mechanism, however, there is a resulting relative movement between the sensor member (40) and the drive pulley (34). Such relative motion preferably activates a switch (80) that provides a signal that indicates a failure of the normal operation of the drive mechanism (30). Another example sensor includes a sensor member (202, 212) that engages a drive belt (35). If the belt (35) breaks, the sensor member (202, 212) moves to provide an indication of the broken belt condition. Various braking application modes are possible using the invention.

Abstract: A method and device for electrically braking an electric drive in a machine for processing printing material, includes a power electronics connected between the electric drive and a DC voltage intermediate circuit. A further electric braking device is switchable between the electric drive and the power electronics. Upon a failure of a power system, a computer initiates a generator-type braking operation through the power electronics. The further electric braking device is switched on upon the failure of the power electronics.

Abstract: A printing press includes at least one printing unit having a cylinder and a cover covering the cylinder. Actuators are associated with the cylinder for changing a geometry of the cover in axial and/or circumferential direction of the cylinder. Positioning electronics are connected to the actuators and a printing press machine control system is connected to the positioning electronics. An image inspection device is connected to the printing press machine control system at least for geometric measurement of printed printing materials. A printing press computer processes measured results from the image inspection device for carrying out a desired/actual value comparison and for driving the actuators to minimize determined deviations, in the event that deviations are determined.

Abstract: A stepchain for a passenger conveyor includes a plurality of stepchain links (30, 130, 230). There is only one link-to-link interface (31) on each side of the steps (24) such that the number of links (30) on each side of the steps (24) is equal to the number of steps (24). The inventive arrangement reduces rotation or contraction of the stepchain between steps (24). Elongation of the stepchain is also reduced as there is a reduction in the number of interfaces (31). The inventive arrangement also facilitates arcuate movement of the steps (24) along a constant radius through the transition zones between the inclined area (27) and the landing areas (29). Having a truly arcuate movement allows for reducing the gap (33) between the steps (24) at the transition zones. In one example at least one needle bearing (190) is associated with an attachment mechanism (184, 284) at the interface (31) between adjacent links (30) to allow for rotation between the stepchain links (30) and to eliminate the need for lubrication.
