A method of image restoration in an image processing system is provided. The locking member is configured to lock the arm in a substantially fixed state to inhibit movement of the arm relative to the housing when the locking member is in an engaged position, and unlock the arm from the substantially fixed state to allow the arm to steer the fin relative to the housing when the locking member moves from the engaged position to a disengaged position. According to the present invention, by using this process and novel purification methods, essentially as described herein, highly pure Imiquimod is obtained. In the method, the composition is applied prior to exposure to the sun; for direct acting MMP inhibitors, application should be just prior to exposure, and if indirect inhibitors such as retinoids are used in addition, then application of the indirect inhibitor should be at least about seven hours prior to exposure. The terminal may send channel quality indication reports for the FL carrier in each group via the RL carrier in that group. The clean out housing is configured with a mechanical cleaning implement supported for movement through a first fluid conduit that passes through a vessel hull for scrapping debris from the side walls of the first fluid conduit when the conduit becomes fowled.
