Abstract: An NMR rotor comprises a receptacle for inserting a sample container into a homogeneous region of an NMR magnetic field with flux density B, the field vector of which in the homogeneous region extends in the vertical direction along a z-axis. The rotor passes through regions with inhomogeneous magnetic field components and a flux density gradient dB/dz when the sample container is introduced. The rotor includes at least two different materials, one with diamagnetic properties and another with non-diamagnetic properties. The different materials are arranged to be geometrically distributed in the rotor so that the magnetic force on the rotor under the effect of a product t of magnetic flux density B and flux density gradient dB/dz, the magnitude of which exceeds 1400 T2/m, either acts in the same direction as the weight force of the rotor or is smaller in magnitude than the weight force of the rotor.

Accordingly, the supporting unit is arranged at least partially in the intermediate space and thus a reduced installation space relative to the supporting unit is needed.

Abstract: A method for damping a movement of a door system of a vehicle that is equipped with a damping system having an adjustable and controllable damping action. A movement of the door system between a closed position and an open position is damped in a controlled manner. A measurement of the change in speed of the speed of movement of the door system is calculated and if the change in speed exceeds a predefined limit value, a set, gentle damping action is changed over to a greater damping action.

The detection device has a light source (5a), from which light is introduced into a lower end (6?) of a light guide (6). The stator has a first bore (2a), in which a first light guide stump (7a) is positioned such that, in the loading position of the stator, it produces an optical connection between a rotor inserted in the stator and an upper end (6?) of the light guide opposite the lower end.

Abstract: Selective laser solidification apparatus is described that includes a powder bed onto which a powder layer can be deposited and a gas flow unit for passing a flow of gas over the powder bed along a predefined gas flow direction. A laser scanning unit is provided for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form a required pattern. The required pattern is formed from a plurality of stripes or stripe segments that are formed by advancing the laser beam along the stripe or stripe segment in a stripe formation direction. The stripe formation direction is arranged so that it always at least partially opposes the predefined gas flow direction. A corresponding method is also described.

Abstract: A door component has a controllable damper device that contains a magnetorheological fluid as a working fluid. Two connection units of the damper device can be moved relative to each other. One of the two connection units can be connected to a support structure, and the other connection unit can be connected to a pivotal door device in order to damp a movement of the door device between a closed position and an open position in a controlled manner. The magnetorheological damper device has a piston unit and a cylinder unit which surrounds the piston unit. The piston unit divides a cylinder volume into two chambers. The piston unit has a first piston rod, which extends through the first chamber, and a second piston rod, which extends through the second chamber.

Abstract: A shim system for influencing and homogenizing the magnetic field of an NMR system includes a coil former (1), an extension tube (2) and a terminal unit (3), as well as partial coils (4, 4a) that are mounted on the coil former. Terminal lines (6a, 6b) for connecting the partial coils to the terminal unit are initially electrically disconnected from one another between the coil former and the extension tube. A circuit board (5) with connection lines (5a, 5b, 5c, 5d), however, is interposed between the disconnected terminal lines. This makes it possible to redesign the shim system in the mechanical construction thereof using simple technical measures and standard components, and without giving rise to significant additional costs. Therefore, production of the partial windings on the coil former can take place in a simplified, economical and automated manner, without requiring an extension tube to be already fitted.

Abstract: A protective packaging for sharp-edged objects is disclosed. The protective packaging generally has two shell parts connected pivotally on one side in the area of a pivot axis. At least one of the shell parts forms a first receiving space that is configured to receive an object and provide a free space between for the shell parts and the object, and a second receiving area configured to hold the object in a form-fitting manner. A third receiving space adjacent the second receiving area provides sufficient space for connection of a tool carrier to the object. The protective packaging is therefore designed as a mounting and removal tool rotatable around its longitudinal axis, and the object contained in the protective packaging can be mounted on and removed from any tool holder together with the protective packaging without contact with the hand.

Abstract: A fastening system for attaching an NMR probe to an NMR magnet includes a discoid insert and a retention system that is rigidly connected to the magnet and on which the insert can be mounted. A form-fitting, variable-force connection is established between the NMR probe and the retention system using a spring element. The probe attaches to the insert by a plurality of integral, rigid retaining elements that are of an invariable fixed length. The spring element and the retaining elements are designed geometrically such that in a first, opened state the connection between the insert and the retaining elements has a mechanical backlash between 0.5 mm and 5 mm when the spring element is relaxed. In a second, closed state the connection between the insert and the retaining elements has no mechanical backlash when the spring element is under mechanical tension.
