The invention concerns a method for the computerized allocation of resources to vehicles travelling over a predetermined section. A section (TZR) of an amount of permissible resources (ZR), which are stored in the form of a column-generating graph (SGG), is optimized by an optimization process (OV). By combining a column-generating process (SG) for determining new columns (NS) and the introduction...

Molded products made from gelatinized starch can be made water-resistant by coating with biodegradable polyesters such as poly(beta-hydroxybutyrate-co-valerate) (PHBV), poly(lactic acid) (PLA), and poly( epsilon -caprolactone) (PCL). Adherence of the two dissimilar materials is achieved through the use of an intervening layer of a resinous material such as shellac or rosin which possesses a solubi...

A method is disclosed for recycling fused vinyl plastisols. The vinyl plastisols are comminuted and dissolved in a solvent, such as cyclohexanone, dichloromethane, hexane, chloroform, methyl ethyl ketone or ethyl acetate. A plasticizer is added to the solvent mixture after the vinyl plastisol has dissolved, and the solvent is removed from the mixture under vacuum.; L'invention porte sur un procédé...

When drilling a borehole for an oil well it is desirable to know when fluid is passing through the walls of the borehole between the borehole itself and the formation through which the borehole is passing. It has now been discovered that useful information about the influx or efflux of fluid can be gained by observing the pressure within the borehole in the region of the drilling bit, this observa...

An optically anisotropic diffraction grating for an optical read/write head, comprising optically isotropic polymer liquid crystal held between two transparent base plates. Gratings of different refractive indexes are formed by periodically changing the orientation of the polymer liquid crystal of the diffraction grating. This enables a high light-utilization efficiency and a high reliability to b...
