20090245929 | CONNECTION ELEMENT - A connection element comprising a first retaining element and a second retaining element adapted to be connected by a rotary bearing such that the retaining elements can be freely rotated relative to each other about 360°, characterized in that a first annular rotary bearing portion has a first outer annular portion and a first inner annular portion concentric to the outer annular portion, the first outer annular portion at the inner circumference having a first locking portion of limited length in circumferential direction, a second annular rotary bearing portion has a second outer annular portion and a second inner annular portion concentric to the outer annular portion, the second inner annular portion being matingly accommodated by the first inner annular portion, an annular circumferentially extending locking portion of the second outer annular portion within the first outer annular portion gripping behind the first locking portion when the rotary bearing portions are plugged together substantially in an approximately parallel position relative to each other. | 10-01-2009 |
20130028681 | DEVICE FOR FASTING A COMPONENT TO A FASTENING STUD - A device for fastening a component to a fastening stud includes a holding member and a holding disk for contacting first and second surfaces of the component, respectively. The holding member and holding disk are preliminarily connected with one another, without the fastening stud, each in the state contacting the component. The holding disk has fastening projections and at least one elastic member which prohibits the fastening projections from contacting the second surface of the component, so that the device is moveable with regard to the component in a direction perpendicular to the moving direction of the fastening stud through a through hole of the holding disk. The elastic member is elastically deformed upon mounting of the fastening stud through the through holes of the holding disk and the component, such that the fastening projections contact the second surface of the component. | 01-31-2013 |

20110286479 | Pulsed light source - It is an object of the present invention to provide a compact and low-cost system for generating ultra short high energy laser light pulses that does not use the known CPA scheme. The proposed approach is based on spectral filtering of laser light pulses of a mode locked laser source. The used mode locked laser source can be of any kind as long as its filtered residual pulse bandwidth supports pulse durations longer than 20 ps and up to 1 ns. After filtering the laser light pulses are directly amplified in an amplification element consisting of one or more amplification stages. At the same time or just after amplification the light pulses are spectrally broadened through a spectral broadening element, for example a fiber of suitably chosen core diameter and length to achieve a spectral bandwidth that is wide enough to support sub 10 ps pulses. Finally, the spectrally broadened laser light pulses are compressed by a compact dispersive element consisting of one or more Bragg gratings or a grating pair. | 11-24-2011 |
20120069428 | SINGLE-MODE PROPAGATION IN MICROSTRUCTURED OPTICAL FIBERS - The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide. | 03-22-2012 |
