Abstract: A process and apparatus for separation of solvents from an air stream laden with solvent vapors by adsorption using active carbon followed by regeneration of the carbon by desorption by steam using a plurality of active carbon chambers. The sequence of charging and regeneration of the active carbon is controlled automatically in dependence upon the concentration of solvent vapors in the air stream. During the change over from charging to regeneration the active carbon is first subjected to desorption by steaming with a large volume of steam and then, when steam breaks through on the outlet side of the carbon the volume of steam is reduced for the purpose of drying the carbon. The change over is effected by a measuring device arranged on the outlet side of the carbon chamber responsive to a pre-determined threshold concentration of solvent vapors in the outgoing stream.

Abstract: Optical fibers in long line communication links fail often in tensile strength. Analysis of tensile properties reveals a variation in tensile strength with fiber length, pointing to uncommon structural defects randomly occurring along the fiber length. Failures occur from crack propagation at these defects. The defects can be revealed according to the invention by nondestructive monitoring during production via off-plane light scattering. A narrow light beam incident across the fiber diameter is refracted in a pattern characteristic of the fiber geometry. Variations in that pattern are produced by structural variations in the fiber or by surface contamination. The nature of the pattern change can indicate the type of defect.
