IPC: B29C41/22
Filed: 1990-09-14
Abstract: In the manufacture of a multi-coloured skin by the powder slush moulding process, one-piece slush skins (24, 26) are respectively formed in successive process steps, the said skins extending over the entire mould (10), which is divided into individual colour zones (14, 16) by means of dividers (18). Once the first slush skin of the first colour has been manufactured, the area assigned to a different colour is separated off and partially demoulded, the other part of the slush skin remaining behind in the mould. After that, a complete second slush skin is formed both in the previously demoulded subarea and in the area of the first slush skin remaining behind, and so on. Viewed from the textured side, a multi-coloured slush skin (32), which is distinguished by an exact and visually clear parting line (34) between the individual colour areas, is then obtained after final demoulding.

Patent DE-4041854-A1 (DE)
Inventor: HOVELING STEFAN DIPL ING
IPC: C22F1/08
Filed: 1990-12-24
Abstract: Under normal atmospheric conditions, a uniform green covering layer, the so-called patina, forms on inclined copper surfaces only after exposure to the weather for many years. There has long been a desire to effect preweathering of the surface of semifinished products consisting of copper in the works on a large industrial scale, closely simulating the natural green patination. The method according to the invention for producing an artificial green protective and covering layer comprises first roughening the surface of degreased strip or sheet in a controlled manner by a mechanical treatment. In a further step of the method, the roughened surface of the strip or sheet is then treated in continuous flow with a suitable chemical reaction solution for green patination. After the chemical treatment, the strip or sheet is stored in its final dimensions for some time in an air-conditioned room.
Patent DE-4108048-A1 (DE)
Inventor: MEICHSNER WALTER DIPL ING
IPC: C21B5/00
Filed: 1991-03-13
Abstract: The invention relates to a method for fluidising and pneumatically conveying a fine-grained solid material from a pressure conveyor receptacle (1), where, of the three gases at different pressures P1, P2 and P3 fed to the solid material, the gas stream at middle pressure P2 is guided into the receptacle above (3) the solid material, the gas stream at higher pressure P1 used to fluidise the solid material is guided into the lower conical area (6) of the receptacle and the gas stream at lower pressure P3 is guided into the conveyor line (11) which is connected thereto, the gas stream at higher pressure P1 used to fluidise the solid material being divided up into a multiplicity of separate gas streams. The invention is characterised in that:   - the separate gas streams are collected in groups to make tubular fluidisation elements (13), - some of the separate gas streams being normal to the wall of the container and - some of the separate gas streams being introduced to the solid material at an angle deviating from the normal to the wall of the container and - the directions of all separate gas streams being made to correspond to one another in such a way that an essentially horizontal rotating current is generated at least in the areas of the fluidised solid material adjacent to the conical wall of the container.   <IMAGE>
