IPC: C01B15/10
Filed: 1991-09-03
Abstract: Process is for melt-appln. of a finely divided solid coating materials, solid at room temp., where the finely divided solid material is injected as a continuous stream into the continuously produced spray mist zone of the molten coating material, for anhydrous encasing of solid Na percarbonate with a hydrophobising jacket of coating material which is solid at room temp. In Na percarbonate with a protective layer of a water-repellent coating material, esp. for use in solid washing and/or cleaning compsns., the protective layer, or at least the innermost layer is applied by this method. The encapsulated Na percarbonate does not agglomerate, is free flowing, and has particle size 0.1-2 mm. Stabilisers for Na percarbonate, esp. complexers for bonding metals, may be in the Na percarbonate core and/or in the encasing material. The residence time of the Na percarbonate in the molten spray zone is pref. less than 1 sec. (less than 0.5 secs.), and the freshly coated Na percarbonate is cooled immediately, pref. in a stream of cooling gas, esp. an air/liq. N2 mixt. in amt. so the freshly applied casing on the cooled material does not adhere. The coating material is organic, pref. paraffinic, with COOH, alcohol, ether and/or ester gp(s). The solidification point of the coating material is 40-150(45-110) deg.C, and mixts. have a narrow range of m.pt., pref. not more than 10 (not more than 5) deg.C. The temp. of the sprayed coating material in the spray mist zone is 10-50 deg.C above the m.pt. of the coating compsn. ADVANTAGE - The Na percarbonate has better storage stability.

Title: Lamination of panels, used for interior car trim - comprises applying 1st surface layer, cutting to shape, applying 2nd surface layer, joining on and cutting off the excess gives clean joint
Inventor: KERN H-JUERGEN DIPL ING
IPC: B60R13/02
Filed: 1992-02-10
Abstract: Lamination comprises applying a 1st surface layer cutting to shape; applying 2nd surface layer; joining on and cutting off the excess. The 1st layer (2) is cut normally and then trimmed by an ultrasonic cutting blade (7). The depth of cut is controlled by one or more depth stops (14,15) which are attached to the non-vibrating part of the blade carrer (6). The 2nd surface layer can be cut and trimmed in a similar way. The blade (7) can be double-edged (8,9) and the depth stops (14,15) can also be guiding elements to lead the blade along the desired contour. The depth stops (14,15) can be built as contact sensors. An automobile door panel (1) has part of its surface covered by a fabric (2) which joins on to another covering of textured synthetic film. The fabric covering (2) is roughly cut to shape and is then trimmed accurately by an ultrasonic cutter (7) attached to a robot arm (12) to give the required profile. The synthetic film covering is similarly cut to accurate shape and the edges joined by high frequency welding. Alternatively, the two layers can be placed on top of each other and the desired shape cut simultaneously in the two layers. USE/ADVANTAGE - The invention produces a clean join without the danger of damaging adjacent surfaces.
Patent DE-4206671-A1 (DE)
Inventor: KOEPPLER HORST
IPC: D01H5/02
Filed: 1992-02-28
Abstract: The invention relates to a gill box in a spinning preparation machine used to even out individual fibres within a fibre web and make them parallel. According to the invention, the slots (6) in the slotted cams (5) for guiding the gills (4) are in an oblique plane which gives the gills (4) an additional sideways movement during the movement of the gills (4) into and out of the fibre web. This has the advantage that fibre bunches in the fibre web can be loosened and run better in the subsequent stretching process, whereby the evening process is facilitated and the quality of the yarn in the subsequent spinning process is substantially improved.

Title: Shock absorber mfr. in two part injection moulding method - giving two areas of different hardness produced using different material
Inventor: WEYERSTALL BERND
IPC: E05B85/04
Filed: 1992-07-22
Abstract: Mfg. of shock absorber brackets (1) for door fasteners in vehicles consists of injection moulding the shock absorber element (4) in two parts. The parts of the element which are to have a lower hardness are moulded while the area of higher hardness are closed off to area of higher hardness are closed off to the injection material. Once the material is sufficiently set, the other areas are opened up and a second harder material is used to mould the harder areas. These areas are automatically moulded onto those areas of lower hardness. The element is then fitted into the hollow area in the metal bracket(s). The harder areas are made of polyacetal plastic and the softer areas of thermoplastic rubber. ADVANTAGE - The materials used have the optimal properties required with the areas (8) subjected to contact with moving objects, being harder and tougher than the remaining areas (4).

Filed: 1992-11-26
Abstract: A process is disclosed for desulphurating an at least H2S-containing crude gas stream (1) in a Claus plant (A), by post-combustion (B) of the Claus waste gas and by scrubbing (C) the waste gas from the post-combustion for SO2 removal, the SO2 (5) recovered by scrubbing being returned to the Claus plant. In the Claus plant, from 60 to 90 %, preferably from 67 to 85 %, in particular 67 to 80  %, of the sulphur contained in the crude gas are directly removed from the crude gas and from 33 to 10 %, preferably from 25 to 10 %, in particular from 20 to 15 %, of the sulphur originally contained in the crude gas are returned as SO2. Gas scrubbing for SO2 removal is advantageously carried out by means of a physical absorption agent. A crude gas partial stream may be directly led to the post-combustion, bypassing the Claus plant. Besides a Claus furnace operated at a temperature between 850 and 1300  DEG C, preferably between 900 and 1100  DEG C, the Claus plant may have one or several catalytic and/or thermal reactors for sulphur generation and sulphur recovery condensers, or it may use only thermal sulphur generation stages or it may consist of a direct oxidation Claus plant.
