Abstract: In a method for treating waste products and recycling products of solid organic or inorganic materials or composite materials or mixtures thereof, a breaking-up or separation of the components by means of an impulse is effected in the composite material or the mixture by a device which suddenly interrupts the flow of said composite material or mixture. Process air is fed in a counter-rotating, rising flow path into the spiral-like downward transport path generated in a rotor having a vertical axis and a shockwave is generated between the layers of the composite material against a deflector wall of the rotor. In addition, two radially spaced, coaxially arranged wall faces rotate relatively to one another about their axis and the composite materials or mixtures moved by centrifugal forces are moved and broken up between deflector faces projecting radially from the deflector walls.

Abstract: A glass container inspection machine is disclosed for inspecting glass stippled bottles for defects. Stippled bottles are supported at an inspection station and are illuminated with a light source. The stippled bottle is imaged a pixel matrix with the pixels of the image varying in intensity from bright to gray at the points of stippling. A computer evaluates the pixels of the image including a look up table for values to be assigned to specific light intensities from light to black, the plot of the look up table having a high gain portion from black to gray and a continuous low gain portion from gray to white.
