Abstract: Device for transmission of movement and compressive force between a force-generating element in the form of a cylindrical body (1) and attached disc-shaped force-absorbing elements (5a,5b) via thin circular plates (4a,4b) of a material with low losses and low reluctance which are placed between the cylindrical body (1) and the elements (5a,5b). The plates (4a,4b), upon loading, are subjected to a relatively great elastic deformation with an ensuing reduced ability to transmit movement and compressive force. By perforating these plates with a number of evenly distributed holes (7) provided with pellets (8) of a stiff resistant material with an axial length of at least the thickness of the platesl these pellets take over the duty of transmitting movement and compressive force between the cylindrical body (1) the elements (5a,5b) without the plates (4a,4b) being elastically deformed.

Abstract: A laser (1) is applied on the side of a channel which is traversed by a medium. The light beam from the laser (1) passes across the channel. Particles (5) in the medium within the measuring volume are hit by light and deflect this, thus creating forwardly-directed light cones. These light cones are refracted outside the channel by a lens (6) and thereafter hit a detector plate (8). The light which hits the detector plate (8) occurs in the form of light rings which have arisen by light diffraction. On the detector plate (8) at least two detector rings are arranged, consisting of light-sensitive elements adapted to measure the light power in those light rings which fall onto the light-sensitive elements. In an electronic differentiating unit (9) a difference is created between the measured light power values from two of these detector rings. This results in a difference signal which can be related to the size distribution of particles occurring in the flowing medium.
