Abstract: A device for twisting hairpin ends of a coil formed from hairpins for an electric machine includes: a plurality of coaxially arranged twisting rings having: two outer twisting rings and, therebetween, at least at least two inner twisting rings. The twisting rings have, in each instance, at an axial end facing hairpin ends, a plurality of pockets distributed over a circumference for receiving a hairpin end, respectively. The twisting rings are twistable in opposite directions relative to one another, the twisting rings having couplings by which twisting rings with like rotational direction are connectable.

Abstract: A device for creating a temporary protective space for an elevator system is installed in an elevator shaft and includes a fastening element that can be fixed in the elevator shaft and a supporting element connected to the fastening element. In a maintenance position of the device, the supporting element is arranged such that a movement path of a travel body of the elevator system is limited to form the temporary protective space. An impact element is connected to the supporting element and, in the maintenance position of the device, provides direct mechanical contact with the travel body. The impact element is pivotably mounted on the supporting element such that in an operating position of the device the movement path of the travel body is maximized.

Abstract: A car for an elevator in an elevator shaft is suspended substantially in the center of gravity thereof at least in a ratio of 2:1 by a carrying apparatus guided via pulleys and is guided through car guides. The car has a car base, a car roof and car walls that define a passenger space. For using the car in a machine room-free elevator, to provide a shaft cross-section as large as possible and to reduce the required shaft pit depth and/or the required shaft head height, at least a first part of one of the pulleys is located between the car base and the car roof and a second part of the pulley is located in the car base or at the same height as the car base or in the car roof or at the same height as the car roof.

Abstract: A housing arrangement for a radar sensor includes at least one tubular body and a shielding device for radar beams. The at least one tubular body has a distal end which has a lens mounted therein, and a side wall. The shielding device is arranged on the side wall on an outer side of the at least one tubular body. The at least one tubular body is made of a dielectric plastic. The shielding device is made of a metal.

Abstract: A sensor device for determining a position of seeds while sowing. The sensor device includes a radiation assembly which generates an illumination radiation oriented towards a target area, and a detection assembly. The radiation assembly includes a radiation source which provides an emission spectrum of the illumination radiation covering a spectral range. The detection assembly includes a radiation detector which detects an incident radiation, and a filter member with an attenuation band and a pass band. The radiation detector includes a field of view. The pass band has an attenuation which is less than an attenuation of the attenuation band in a wavelength range where the wavelengths are longer than those of the attenuation band. The target area and the field of view intersect. The radiation source and the radiation detector form a triangulation arrangement so that a distance from the target area to the detection assembly can be determined.

Abstract: A control device for controlling a height of a boom of a vehicle. The control device includes a transmission/receiver set, a processor, a control, and a communication interface. The transmission/receiver set transmits an initial measuring signal and receives an initial reflection signal in response thereto, and transmits a second measuring signal and receives a second reflection signal in response thereto. The processor determines a majority of initial reflection components of the initial reflection signal, a majority of second reflection components of the second reflection signal, and compares the initial reflection components with the second reflection components to determine matching reflection components. The matching reflection components indicate a layer of reflection objects. The communication interface links the processor with the control and to determine a control signal for controlling the boom based on the matching reflection components.

Abstract: A wind power rotor with measuring device (3) for measuring rotor deflection. A measuring cavity (20), which has a transmitter/receiver (31/32) at one end and a reflector device (33) at the other end, extends in a longitudinal direction of the rotor. The transmitter/receiver (31/32) is accommodated in a housing (50), which is fastened to an intermediate plate (10) with three-point mounting (12, 13, 14).

Abstract: A device and process for measuring the deformation of a rotor blade under stress is provided. A twisting and, separately therefrom, a lateral displacement of a transmitter/receiver is measured and the error of measurement present otherwise due to the twisting is compensated.

Abstract: A rack and pinion steering gear comprising a thrust element disposed in a housing for pressing a rack and pinion against one another. One side of the thrust element is supported against the rack, and another side is supported against a wedge-like part formed of two semi-circular annular elements, each of which is provided with at least one wedge surface that is disposed at an angle to a central plane of the wedge-like part. A side of the wedge-like part remote from the thrust element is supported against a set screw. The thrust element and/or the set screw is provided with an inclined surface that cooperates with the at least one wedge surface of the annular elements of the wedge-like part.
