Abstract: An attachment (1) for attaching to the front of a road-sweeping machine (2) has a frame (3) which is guided by means of supporting rollers (4) over the surface (5) of a road, in particular of a road tunnel which has let into its surface reflectors (8) which have to be cleaned. For this purpose, a cleaning brush (9) with its axis of rotation (10) parallel to the direction of travel is arranged in a downwardly open housing (11) inside of which are arranged water-spraying nozzles for water mixed with washing fluid. The housing (11) for the cleaning brush (9) is suspended by means of guide rollers (14) on rails (13) arranged transversely with respect to the direction of travel to allow the to-and-fro movement of the housing by means of a hydraulic cylinder (11a), so that particularly the reflector surfaces of the reflector (8) which point in the direction of travel are cleaned by the transverse motion and high-speed rotation of the brush. A shower arrangement (15) disposed behind the cleaning brush in the direction of travel comprises, inside a housing, water-spraying nozzles for rinsing away the washing fluid. Located behind the shower arrangement in the direction of travel is a blowing nozzle (17) through which drying air is blown, a fan arranged on the road-sweeping machine (2) supplying the air via a line (19). The apparatus permits a rapid cleaning operation over long tunnel sections by means of only one... Original abstract incomplete. <IMAGE>

Abstract: Magnetic structures of a sample (46) are imaged by measuring Lorentz force-induced deflection of the tip (40) of a scanning tunneling microscope. While scan­ning the sample (46), an a.c. voltage signal at a first predetermined frequency equal to the resonance frequency of the tip (40) is applied to the tip (40) for generating a current between the tip (40) and the surface (44) of the sample (46) for causing the tip (40) to undergo vibratory motion relative to the sample (46). The tip (40) motion, indicative of the presence of a magnetic field, is optically detected. In an alter­native embodiment for providing improved resolution the tip (40) is made to undergo motion at a second predetermined frequency in a direction parallel to the longitudinal axis of the tip (40) and normal to the surface (44) of the sample (46). The tip (40) motion is optically detected at the sum or difference fre­quency of the first and second predetermined fre­quencies for providing improved lateral resolution of the magnetic field measurements using a scanning tunneling microscope. In the alternative embodiment the sum or difference frequency, which ever is de­tected, is made equal to the resonance frequency of the tip (40). The magnetic field measurement and tip (40) position are provided to a computer (68) which, in turn, provides an output signal to a device (72) for providing a graphical representation of the magnetic field at different positions on the surface (44) of the sample (46).
