Title: Co-extruded decorative plastics trim strip - features a variable thickness of decorative layer, leading to variation of colour intensity
Inventor: CAKMAKCI MEHMET Y
IPC: B29C48/07
Filed: 1990-10-10
Abstract: Appts. for producing a co-extruded plastics decorative strip, suitable for automotive trim, consists of a co-extrusion die in which a decorative layer is extruded on the upper surface of a base strip. The decorative layer is extruded in a thickness which is constant along the extrusion length but which varies across its width, thus producing a decorative variation of colour intensity. The thickness variation is produced by the die profile aided by a flow restrictor dam in the coloured material flow path. - A generally conventional thermoplastics co-extrusion die is fed by a first extruder to produce a base strip (11), typically of PVC or polyolefin, which may opt. be recycled material. The strip proceeds in the soft state to a directly communicating die (31) where a second extruder feeds a coloured like material through a channel (38) to a feed chamber (40), consisting of an upper and lower passage (42, 43), sepd. by a flow restrictor dam (44) whose surface is spaced pref. by 0.4 mm from the die plate thus allowing a small flow of coloured material from the upper to the lower passage. The dam (44) is bypassed by first and second feed channels (48, 49) through which the major flow occurs. In co-operation with a suitably shaped die plate, a layer of coloured plastic of variable thickness is co-extruded on the surface of the still soft base strip (11) and around its edges (15, 16) where it melt bonds. The strip proceeds conventionally to takeoff and cooling. In other embodiments, various surface profiles are envisaged for the strip.
Patent DE-4032457-A1 (DE)
Title: Plastics strip for paper-making rollers -  has holes to take off extracted water formed by heated punches
Inventor: AUFRECHT HARALD
IPC: B26F1/10
Filed: 1990-10-12
Abstract: To form holes or grooves in elastomeric and/or thermoplastic strips, especially for cladding rollers in papermaking to take up extracted water from the fibre pulp, heated punches are pressed into the material. The cross section of the punch matches the contour of the hole to be produced, and the punch temp. is equal to the evaporation temp. of the material. The material is passed by a guide through the processing station, where a carrier fitted with punches extends across the material width and parallel to the material and structured to cover the material length either as a beam or a rotating roller. The free ends of the punches are heated, and drive systems bring the material guide and the heated punches into contact with each other. Where the material passes round a guide rollers, the punch carrier roller and the material surface move at the same speed and in the same direction. When using a punch beam, with at least one extending heated punch, the material and the beam are moved against each other vertically. The punches can be arranged so that the holes formed in the plastic material are at an angle from the material surface. After the holes have been formed, the material is cleaned by brushing to remove any debris from evaporated plastics material or parts of any clinging protective film. ADVANTAGE - Clean and trouble-free holes can be formed in the plastics material, at low cost and in a short time, with virtually no tool wear.

Patent DE-4129533-A1 (DE)
Inventor: REDEMANN NORBERT
IPC: A61K38/45
Filed: 1991-09-05
Abstract: Mutated receptor tyrosine kinases are useful as medicaments. These mutated growth factor receptors are particularly advantageous for treating cancerous diseases, in particular those types of cancer in which the overactivity of growth factor receptors play a role in the formation of the cancer, as well as for treating other diseases caused by receptor overactivity. Mutants of the EGF receptors in which the tyrosine kinase activity of the wild type receptor has been eliminated by punctual mutation or deletion in the tyrosine kinase domain are particularly effective medicaments for treating cancer.
