Abstract: A device for producing a spur toothing includes a tool holder arranged for rotational drive about a drive axis and longitudinal displacement along the drive axis, and a tool arranged on the tool holder. The tool includes an end face, a mating toothing disposed on the end face and arranged for forming a spur toothing on a workpiece, and a longitudinal axis arranged at an angle to the drive axis such that the longitudinal axis meets the drive axis at a wobble point. The mating toothing has a tooth base plane and the wobble point is disposed on the drive axis in front of or behind the tooth base plane such that, through rotary drive and longitudinal displacement of the tool holder with the associated wobbling rolling of the tool on the workpiece, the spur toothing formed by the mating toothing has a number of teeth that is unequal to a number of teeth of the mating toothing.

Abstract: If a failure of components of a transport-system sliding contact can be predicted, preventive maintenance that is sometimes unnecessary is eliminated and an alternative run-to-failure approach associated with downtime can be avoided. A system and a method detect wear of a transport system, which system has a sliding contact with a current collector mounted on a vehicle and a current-carrying conductor. The vehicle travels along the current-carrying conductor, the current collector being pressed against the current-carrying conductor. Vibrations produced during the driving motion are registered by a vibration sensor attached to the current collector and wirelessly transmitted to a background system. The background system is configured to subject the transmitted data, in particular the registered vibrations, to an analysis and to signal wear of the transport system, in particular wear of the current collector and/or of the current-carrying conductor, on the basis of the analysis.

Abstract: A holding element for a drape for a surgical microscope is provided. The holding element has a holding ring and a recess located in the holding ring for an interface of the surgical microscope. The holding ring has an asymmetrical contour delimiting the recess such that in a condition in which the holding element is fastened to the surgical microscope there is only one possible fastening position of the holding element on the interface of the surgical microscope that corresponds to the contour of the holding ring, in which position an orientation of the holding element relative to the surgical microscope is defined.

Abstract: A system and a method for condition monitoring during the operation of a conveyor system, in particular an airport baggage conveyor system, includes conveyor units and a background system. A conveyor unit includes an individual conveyor line and/or a group of conveyor lines. It is possible to record an individual current characteristic of an individual conveyor unit. Each individual conveyor unit has a defined current characteristic during fault-free operation and the background system is configured to record the defined current characteristic and the actual current characteristic of the conveyor unit. The background system is configured to analyze the actual current characteristic of the conveyor unit and to signal, on the basis of the analysis, an impending wear and/or a malfunction of the conveyor system, in particular of a conveyor line of the conveyor unit.

Abstract: An apparatus (1) comprising hardware equipment (3) having hardware components (10) enclosed by a chassis (2) having a front side (2A) and a rear side (2B), and auxiliary equipment (5) movable within the chassis (2) along at least one transportation rail (7) with a non-linear trajectory extending in horizontal plane between a first position at the front side (2A) of the chassis (2) and a second position behind the hardware equipment (3) at the rear side (2B) of the chassis (2), wherein a part of the hardware components (10) is at least temporarily removable from the chassis (2) or movable within the chassis (2) to provide space (11) for moving the auxiliary equipment (5) within the chassis (2) along the at least one transportation rail (7) between the first and second position.

Abstract: Airport luggage carousels are usually operated in a run-to-failure approach that necessarily leads to failures. Anomalies are detected during operation of a conveyor system having a revolving drive chain, a drive unit and a conveyor belt. The drive chain serves to transmit force and motion from a drive unit to a conveyor belt, and has chain elements and pins connecting them. At least one of the pins is a force measurement pin that registers the forces acting thereon during movement of the drive chain. The registered forces are transmitted wirelessly to the background system together with a timestamp and/or a location stamp and an identity of the force measurement pin. The transmitted data are analyzed in the background system and, in the event of deviations, identified as an anomaly and signaled by a notification. The measurement results are evaluated to derive maintenance measures in a targeted manner.

Abstract: If a failure of components of a transport-system sliding contact can be predicted, preventive maintenance that is sometimes unnecessary is eliminated and an alternative run-to-failure approach associated with downtime can be avoided. A system and a method detect wear of a transport system, which system has a sliding contact with a current collector and a current-carrying conductor. A current-collector vibration sensor mounted on the current collector is configured to register vibrations produced by driving motion of the vehicle along the current-carrying conductor and to wirelessly transmit the vibrations to a background system. The background system is configured to subject data transmitted to the background system, in particular the registered vibrations, to an analysis and to signal wear of the transport system, in particular wear of the current collector and/or of the current-carrying conductor, on the basis of the analysis.

Abstract: A method for wear detection during the operation of a conveying system having a closed circulating path, a pick-up which is attached to at least one running gear and which makes contact with a surface of a rail in the case of wear of the wheel and/or the rail, includes using a sensor coupled to the pick-up to register vibrations produced by the contact. The vibrations are transmitted wirelessly to a background system and are evaluated. The method and a conveying system allow wear detection, in particular in the case of closed conveying systems, and considerably reduce maintenance complexity.

Abstract: A protection glass adapter for a surgical microscope has a first abutment surface which can be brought into contact with a corresponding second abutment surface of the microscope. The adapter has a guide opening for receiving a main objective. The guide opening is a truncated cone with a central axis. The greater diameter of the truncated cone is formed toward the first abutment surface. A positioning element of the adapter is rigid and arranged on the first abutment surface. The positioning element is received with form-fit engagement in a mating element on the surgical microscope. The adapter has a holding element. A holding force in the form of a magnetic force can be applied by the holding element parallel to the central axis between the adapter and the microscope.
