Patent DE-19651855-A1 (DE)
Inventor: BACKHUS FRIEDRICH
IPC: C05F17/02
Filed: 1996-12-13
Abstract: The invention relates to a device for processing and/or displacing preferably filling-type accumulations (stacks) of material which can be composted or general dumping material. Said device comprises track clearers protruding form the front of the travel sections when in working position. Said track clearers can pivot around an angle of incidence range to enable adjustment of a diagonally ascending angle of incidence with respect to the horizontal or to the ground from an approximately horizontal position around an incident axis. The invention aims at providing a device of the above-mentioned type, which is more resistant and economical and which can be at least partially assembled, maintained and repaired even in countries that have relatively unsophisticated infrastructure and limited technological development. This is done by providing each track clearer with a guide track which is positioned according to the corresponding incident axis, which predefines the angle of incidence range of the track clearer and guides a guiding element of the track clearer.

Patent DE-19735337-A1 (DE)
Title: Bobbin winding of melt spun filament yarns
Inventor: BUSSE KLAUS DIPL PHYS
IPC: B65H61/00
Filed: 1997-08-14
Abstract: The operation to wind a number of yarns of melt spun filaments, into bobbins, has a number of neighbouring bobbin sleeves which are rotated together. A monitor registers the filaments, and the running time is recorded by programming adjustable target running times for different target bobbin weights. In the event of a break, the fractured filament is diverted and a cutter is activated. On winding, initially the nominal running time is selected for the highest and at least the second lowest target bobbin weight, from a number of target weights and, on a yarn break, the severed yarn is diverted between two target weights. The nominal target weight is automatically programmed to the following and next highest target weight and, on reaching the nominal running time, the cutter is activated. The programming uses at least seven target weights which can be modified. The assembly uses at least four, or six or ten adjacent bobbin sleeves being wound at the same time.
Patent DE-19745642-A1 (DE)
Title: Refurbishment of encrusted pipelines for water supply, e.g. removal of lime scale
Inventor: SCHAAF MICHAEL
IPC: B24C3/32
Filed: 1997-10-15
Abstract: The line is emptied and dried for coarse cleaning. This is effected using jetting medium suspended in fluid. The fluid is acid, acid-air mixture or water-air mixture. Cleaning is completed using an acid. The line is then passivated in two stages. The internal surface is completed by a coating of plastics. Preferred features: A mineral acid is used, at a concentration of 10%-30%. The surface finish resulting from final cleaning has a roughness of 10-30  mu m. The jetting mixture is passed in a circuit through the pipeline, moved back and forth in it, or pulsated during flow. First and second passivation stages are carried out by a 5% alkaline liquor at a pH above 11. The jetting particles are 0.2-0.8 mm in size. A final jetting with medium of 1-2 mm size,  prepares for the surface coating. The jetting velocity is 6-15 m/s. Solids proportion in the medium is 20%-65%. Two-component epoxy coats the surface. Shore hardness of the epoxy is 85-87. Plastics is coated in two stages. Total thickness of both coatings is 700-1000  mu m. When the line supports little or no flow, the work is preceded by a mineral acid soaking at 10%-30% concentration. The temperature of the acid is 60 deg C. In a complex pipeline system, valves and other equipment are removed, and substituted by pipe sections. Coating plastics is filled into the line with the aid of over- or under pressure. Air is displaced by the plastics influx, from gaps in the line left by fittings and equipment. As the plastics reaches the gap, the tubing section is fitted in. On completion of lining, excess plastics is blown out and setting is completed with an air flow, at about 70 deg C. The result is inspected optically, electrically or optoelectrically. Spark breakdown testing is carried out. Coating thickness is examined. The acid contains an inhibitor protecting metal of the pipeline against its effects. The passivating medium contains an inhibitor protecting against suspended rust. The pH value of the acid and/or the first or second passivating medium  is measured. If appropriate correction is made, for example on a departure exceeding 1.5, below the passivation medium normal pH of 11.0.
