  • Patent number: 11435527
    Abstract: An optical fiber cleaving device (1) has a knife (3) and two clamping arrangements (6a, 7). A first clamping arrangement (6a) includes an element (8a) configured to receive a light-radiation-curing adhesive (11) together with an end portion (5a) of the fiber (5), which is embedded in the adhesive (11). A lamp (15) is configured to apply light on the adhesive (11) to cure it so that the end portion (5a) of the fiber (5) is firmly bound to the element (8a). The end portion (5a) is in this way fixedly held during cleaving of the fiber (5). A method is also provided for cleaving an optical fiber (5), in which the fiber (5) to be cleaved is clamped using light-radiation-curing adhesive (11), as well as use of a fiber cleaving device (1).

  • Patent number: 11041924
    Abstract: A method for determining a spoiler gradient of a magnetic resonance (MR) system is provided. At least one shim parameter that defines a shim magnetic field for compensating for B0 magnetic field inhomogeneities in a measurement volume of the MR system is received. As a function of the at least one shim parameter, at least one spoiler parameter that defines a spoiler gradient for canceling out a transverse magnetization is determined. The spoiler gradient is applied together with the shim magnetic field in a measurement of the MR system.

  • Patent number: 10434675
    Abstract: An apparatus for and method of removing a protecting synthetic coating (1) from an elongated element (2) in the form of an optical fiber (3) surrounded by the coating wherein a cut (8) is created into the coating by knife edges (6). The element is displaced with respect to the knife edges in the longitudinal direction of the element for displacing coating material (17) by the knives. At least one drop of liquid (12) with wetting properties is supplied to the cut for being sucked into a space created between the coating and the optical fiber during the displacement for acting as a lubricant for sliding the coating along the fiber to remove the coating from the fiber.

  • Patent number: 7896208
    Abstract: A method for cleaving thin rods of glass or quartz with a rod cleaving blade (27) and body (28) carrying the blade, is provided. The body (28) is of material varying in length through application of electric and/or magnetic fields. Driving force (31, 33) achieves relatively steady movement of the blade (27) towards a desired cleaving point and relatively steady small-amplitude vibratory component of movement towards and away from the cleaving point superimposed to the relatively steady movement, by influencing the body (28) electrically and/or magnetically. The blade is driven to vibrate with a frequency below 1 kHz during cleaving operation.

  • Patent number: 7382126
    Abstract: In a method and apparatus for detection improvement of a weakly-sensitive atomic nucleus type in MR spectroscopy data acquisition using polarization transfer for a strongly-sensitive atomic nucleus type (A) with involvement of an MR-active, weakly-sensitive atomic nucleus type (X), all RF pulses are radiated sequentially, i.e. with defined time interval relative to one another, such that at no point in time of the sequence are different RF pulses radiated simultaneously or overlapping, and the sequence of the RF pulses causes a polarization transfer of the two involved atomic nucleus types (A), (X).
