  • Polarization control apparatus and method
    Patent number: 8189173
    Abstract: Apparatus and methods are used to control a polarization state of a radiation beam. A polarization control unit is configured to modulate a polarization state of at least a part of a radiation beam. A determination arrangement is configured to subsequently determine the polarization state of the at least a part of the radiation beam. A feedback unit is configured to provide signals to the polarization control arrangement based on at least the determined polarization state in order to correct for deviation in the polarization state of the part of the radiation beam from a desired polarization state. For example, the correction may ensure that the polarization state of the part of the radiation beam is at, or returns to, the desired polarization state.

  • RAIL TRACK HAVING ENHANCED ABSORPTION OF VIBRATION AND SOUND
    Publication number: 20010052550
    Abstract: A rail track comprising at least two parallel rails supported by a non-compressible base body, wherein the base body is provided with a channel-like recess for receiving the rail such that the running surface of the head of the rail lies free, wherein the bottom of the channel-like recess is provided with a first layer of yielding material which extends under the bearing surface of the foot of the rail, and wherein the surface between the running surface and the bearing surface of the rail is covered with a second layer of yielding material, so that an improved vibration damping and sound reduction are obtained.
