Abstract: A method and device for optical measuring of small particles for analysis of the quality of the particles. A sample-feeding carrier is adapted to take up particle samples in sample holders and transport the particle samples to a place for optical measurement. A mirror-supporting means follows the movement of the carrier and has mirrors matching the sample holders. A device illuminates a particle sample when positioned for optical measurement and a detector, which is sensitive to electromagnetic radiation, records a result of optical measurement of the illuminated particle sample. A mirror reflects the particle sample, so that a mirror image thereof stands essentially still seen from the detector, when a measurement is being recorded, owing to the fact that the mirror image of the particle sample falls on a center axis of the movement of the mirror-supporting means.

Abstract: A fishing reel of the multiplier type has a frame, a line spool rotatably mounted in the frame, a brake disk coaxial with the line spool and non-rotatably but axially displaceably arranged in the frame, and a brake unit connected to the line spool and adapted, in cooperation with the brake disk, to brake spool rotation. The brake unit has brake arms with a first end and a second end. The brake arms support at their first end a brake element and are at their second end connected to the holder in a manner pivotable about a pivot axis perpendicular to the line spool axis, so as to be pivoted between an off-position and a braking position, in which the brake elements engage the brake disk. The first end of each brake arm is positioned radially inside its second end. Each brake arm extends in a direction which is so offset from a radial direction in respect of the line spool axis that its first end is positioned in the direction of rotation of the line spool seen behind its second end.
