The invention relates to a ceramic particulate and polymer composite having enhanced viscoelastic and rheological properties. The content of PC in the nonaqueous solvent is at least 10 volume %. A used cylinder liner is removed from the cylinder bore. When a vehicle is driven onto the surface so that the tires of one of its axels are on the tire position areas between the rearward and forward areas, the tires self-center against the scanner windows so that the tire profile may be measured to determine wear and wear characteristics. Furthermore, in the same scroll compressor, chip seals are provided respectively in two grooves, and join paths are provided respectively between a high-pressure compression chamber, which is formed with the bottom faces as one section, and the two grooves; the pressure inside the high-pressure compression chamber is used as a pressing force for the chip seals. The baffles are preferably provided with downcomers which permit downward flow of solids and upward flow of gas through the baffles.
