Abstract: PCT No. PCT/EP96/05636 Sec. 371 Date Jun. 16, 1998 Sec. 102(e) Date Jun. 16, 1998 PCT Filed Dec. 16, 1996 PCT Pub. No. WO97/23566 PCT Pub. Date Jul. 3, 1997A thermoplastic molding material based on polyethylene terephthalate contains preferably from 37 to 96% by weight of PET, from 1 to 20% by weight of a polymer material containing preferably polyurethane, and from about 4 to 30% by weight of a pigment-like reinforcing agent comprising metal and/or metal oxide. The molding materials are suitable for processing by injection molding, and the shaped articles produced therefrom have advantageous properties, in particular with regard to a higher density compared with a similar polybutylene terephthalate (PBT) having glass fibers as a filler. The thermoplastic molding material can advantageously be used for small parts and for housing parts for electronic equipment and data devices.

Abstract: PCT No. PCT/EP95/00695 Sec. 371 Date Sep. 9, 1996 Sec. 102(e) Date Sep. 9, 1996 PCT Filed Feb. 25, 1995 PCT Pub. No. WO95/24443 PCT Pub. Date Sep. 14, 1995Magnetic powder and substrate material are separately recovered from finely chopped wastes of magnetic recording media consisting of a polymeric substrate and a magnetic layer present thereon in which finely divided magnetic powder is dispersed in crosslinked or uncrosslinked polymeric binder by treating the finely chopped wastes of magnetic recording media in a solution consisting of the potassium salt of a polyunsaturated fatty acid, or a biodegradable cleaning agent comprising phosphates, surfactants and a complexing agent, and one or more organic solvents or water while being subjected to mechanical action, and separately removing the magnetic powder from the substrate material by washing or sedimentation or in a magnetic separator.
