Title: Polymer moulding prodn. having with vacuum-formed patterned skin - by thermo-forming e.g. PVC and polypropylene@ foam skin, holding it in position on its porous tool and applying e.g. extruded polypropylene@ behind
Inventor: OYAMA KANJI
IPC: B29L31/30
Filed: 1993-04-21
Abstract: A moulding is produced from a resin bonded to a skin which adheres to a body. In the process the skin is made first by vacuum-drawing a resin sheet against a porous embossed surface which resists pressure, and holding the skin in contact with the forming tool used. A suitable fused resin which will adhere to the skin is next poured into a space between the skin in its position and the second mould tools. The two mould tools concerned are clamped together to compress the liq. resin and force it into the space between the two tools and mould the body adhering to the skin. The resin used is pref. an olefin or a twoply combination of PVC film and polypropylene foam. ADVANTAGE - The process vacuum-forms the skin and pressure-moulds the main body in two successive stages but in one common mould. It thus eliminates the existing need to transfer from one tool to another and hence cuts out inter alia (e.g. occlusion of air, loss of time, coarser thickness tolerances, higher tool costs, shrinkage of the skin etc. It produces sharp patterns in the skin.

Title: Process for reducing the formation of coke when used plastics are used in the refinery
Inventor: GEBAUER MANFRED DR
IPC: C10G1/10
Filed: 1993-09-01
Abstract: Thermally pretreated used plastics or mixtures of used plastics can be recycled together with petroleum distillates in refinery plants, such as crackers, visbreakers and hydrogenation plants. A disadvantage is the formation of coke, which occurs even at low temperatures and results in a shortening of the operating times. The process according to the invention is based on thermal degradation of the plastic content in the extruder without addition of the active gases, a progressive temperature profile up to a maximum of 475 DEG C being set in 2/3 of the effective extruder length and a degressive temperature profile up to from 300 to 380 DEG C being set in the final 1/3 of the effective extruder length, and a coke-reducing additive known per se being metered in at the end of the extruder head or before a downstream static mixer in an amount whose concentration after the subsequent mixing-in of the pretreated used plastic content in amounts of up to 20% by weight into the refinery stream is between 10 and 200 ppm in the total feedstock for the petroleum processing step. The pretreatment of the used plastics can be carried out either as an integral step in the refinery plants or externally.

Title: Process for producing a profile-moulding from fibre-reinforced thermoplastic material
Inventor: HOLSTEIN WOLFGANG DR ING
IPC: B29C70/46
Filed: 1993-10-11
Abstract: Process for producing a, in particular bent, profile-moulding (7; 30) from fibre-reinforced thermoplastic material comprising a prepreg (1; 28) by using pressure and elevated temperature and a shaping mould (3, 5; 5'). After the moulding operation, the profile-moulding is cooled, so that its shape consolidates. The prepreg (1; 28) is advanced in a sliding manner into a gap (6) formed between two substantially stationary mould parts (3, 5; 5'), of which at least one (3) has a surface bent in the direction of advancement of the prepreg. The said gap essentially corresponds in its clear dimensions to the profile of the profile-moulding (7; 30) to be formed. The prepreg is advanced in such a way that, under the action of a sliding pressure exerted by one of the mould parts (5; 5'), it substantially assumes the cross-section of the gap (6) and the curvature of the bent mould part (3). <IMAGE>
