  • Patent number: 9694831
    Abstract: A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.

  • Patent number: 9637145
    Abstract: A rail vehicle includes at least one running gear and at least one anti-roll stabilizer which is connected to two different vehicle parts of the rail vehicle. The anti-roll stabilizer includes a torsion shaft disposed on a vehicle part transversally to the longitudinal direction of the vehicle, levers anti-rotationally disposed on the torsion shaft at both sides of the longitudinal axis of the vehicle and a respective draw/push rod for each lever. Each lever is articulatingly connected to one end of the draw/push rod and the draw/push rod is articulatingly connected at its other end to the other vehicle part. In order to reduce the dynamic forces on the draw/push rods in the oblique configuration thereof, imaginary extensions of the draw/push rods intersect at a point which lies approximately on the axis of rotation of the outward rotational movement of the running gear.

    Abstract: Apparatus, methods, and other embodiments associated with nuclear magnetic resonance (NMR) fingerprinting using echo splitting are described. One example apparatus includes an NMR logic configured to repetitively and variably sample a (k, t, E) space associated with an object to acquire a set of NMR signals. Members of the set of NMR signals are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The varying parameters may include the number of echo splitting pulses, spacings between echo splitting pulses, flip angle of echo splitting pulses, echo time, RF amplitude, and other parameters. The NMR apparatus may also include a signal logic configured to produce an NMR signal evolution from the NMR signals, and a characterization logic configured to characterize a resonant species in the object as a result of comparing acquired signals to reference signals.
