Abstract: A sensor is provided comprising at least one transmitter for transmitting a transmission signal; at least one receiver for generating a received signal from the transmitted signal reflected back by the objects; a base unit; a scanning unit movable about an axis of rotation with respect to the base unit for a periodic scanning of the monitored zone; and a control and evaluation unit for detecting information on the objects with reference to the received signal, wherein an inductive energy transmission unit is provided between the base unit and the scanning unit that comprises a first guide element of the base unit and a second guide element of the scanning unit for guiding the magnetic field of the inductive energy transmission; and wherein the guide elements have an L-shaped cross-section. In this respect, the guide elements are divided into at least two respective guide segments in the peripheral direction.

Abstract: A binding for bundles of fibers in which fibers originating from at least one of the fiber bundles wind around the rest of the fibers in a manner locked by tension. Fiber bundles which are to be bound are deformed between deformation members and fibers are removed from at least one of the fiber bundles and are wound in a manner locked by tension around the remainder of the remaining pieces of fibers to be bound. Deformation members are positioned very close to each other, each having a profiled surface, and they can be driven in opposite directions with respect to each other. The fiber bundles which are to be bound are deformed in the gap between the deformation members.

Abstract: A method of and apparatus for binding fiber bundles which reduces an abrupt cross-sectional course at each end of the fiber bundle resulting from the loose ends of the bundles having been removed. The loose ends are, during the binding operation, severed in a fraying manner by abrasive edges and the frayed bound ends are worked into the resulting binding.

Abstract: This invention relates to a method and an apparatus for avoiding untwisting during the formation of a binding of two fiber bundles. The rotational direction of deformation members acting on the fiber bundles is selected to be different in different groups of deformation members in order to reproduce or to increase the original twist during the binding operation.
