Abstract: RECOVERY OF ALUMINUM FROM ALUMINUM-GLASS CLOTH RESIDUES            Abstract of the Disclosure A method is described for reclaiming aluminum from aluminum-glass cloth residues in which the glass cloth fibers are coated with aluminum, the glass cloths having been used for the filtering of molten aluminum.  The method comprises the steps of:  breaking down the residue into small pieces by the action of a rotating multi-blade cutter in cooperation with at least one fixed blade and a contoured screen whereby the residue is continuously chopped until pieces thereof are fine enough to pass through the screen.  This chopping action effectively frees the glass fibers from the aluminum and the resulting freed glass fiber is then separated from the remaining aluminum pieces by air separation.  The recovered aluminum pieces can be then reused in various industrial processes.

The pits may represent frequency-modulated information signals, and the lengths of the pits are independent of the fre-quency of the information signals.  A method and apparatus for reproducing information from this record carrier is disclosed, wherein a light beam is used to scan the tracks of the record medium, and the size of the scanning light beam is changed as a function of the radius of the track which then is being scanned so as to increase the size of the beam when a track of larger radius is scanned.  This control over the size of the scanning beam establishes a constant relationship between the size of the beam and the length of the pits despite changes in the pit length due to the different radii of the tracks.                             -i-

By Means of these computer input signals, an image is calculated of the density distribution of an irradiated patient. This image is free from interference patterns caused by the fact that the detectors are not the same, by non-linearity of detectors or by hardening of radiation. A device of this kind is particularly suitable for medical X-ray diag-nosis.
