Inventor: FISCH HERBERT DR
IPC: C08G18/10
Filed: 1989-02-07
Abstract: Emulsifier-free aqueous polyurethane dispersions are prepared by reacting (a) dihydroxy compounds, (b) diisocyanates and (c) chain extenders to give a prepolymer having terminal isocyanate groups, then reacting the prepolymer with (d) salts of aliphatic aminocarboxylic or -sulfonic acids or amino-containing or hydroxyl-containing tertiary ammonium salts, dispersing the resulting polyurethane in water and, if required, removing the organic solvent by distillation.

Title: Fixing device for a pivotable leaf of a door
Inventor: FEUCHT FRITZ
IPC: E05F3/22
Filed: 1989-02-21

Title: Process for the powder metallurgical production of alloys based on copper containing proportions of chromium
Inventor: KLEES HORST D
IPC: C22C1/04
Filed: 1989-03-07
Abstract: Process for the powder metallurgical production of alloys based on copper containing proportions of chromium which are mixed into the copper powder or a copper powder mixture containing further alloying metals in the form of chromium nitride powder, in which after the mixture is compacted it is sintered at temperatures between 850@C and 1070@C in a reducing or inert atmosphere and the chromium nitride here decomposes with elimination of nitrogen to give finely divided chromium which diffuses readily into the copper matrix and dissolves surprisingly well therein. The process is very suitable for electrolytically produced copper powder which is mixed with hydrides of further metals such as zirconium, titanium or hafnium, with these hydrides likewise decomposing in the specified sintering temperature range with elimination of hydrogen to give finely divided metals. The resulting sintered bodies are free of deleterious coarse chromium inclusions, are readily hardenable and give shaped parts of good strength, high softening temperature and good electrical and thermal conductivity.
Patent DE-3909630-A1 (DE)
Title: Clamping tool for frictional and highly precise clamping of workpieces
Inventor: RENZ RAINER DR ING
IPC: B23B31/30
Filed: 1989-03-23
Abstract: The invention relates to a clamping tool for the frictional and highly precise clamping of workpieces by means of an expanding element held within the clamping tool which in the relieved state fits together with the workpiece with little clearance but in a movable manner and which is acted upon radially with force over a large area. During the action of force, the expanding element widens in a reversible manner and bears frictionally against the workpiece and holds it in position with high accuracy of concentric running and high clamping force. In order to permit a high expanding rate of the expanding element in a closed design of the same, a so-called shape-memory alloy is proposed according to the invention for the expanding element. The shape-memory alloy is operated in the austenitic state with the possibility of reversible, stress-inducible transformation of the structure into the martensitic state. On account of this, the workpieces can also be fitted together with the clamping tools with substantially greater tolerances, which has a favourable effect on the production costs.

Title: Mould for producing (surrounding with foam) a profile of multi-component plastic, in particular polyurethane, at the edge of a glass pane
Inventor: TAUBENMANN PETER
IPC: B29C33/00
Filed: 1989-06-27
Abstract: The mould for surrounding with foam glass panes having a sealing profile comprises a lower part and an upper part. These two parts define a mould cavity 11, which forms the profile and into which the edge of the glass pane 10 to be surrounded with foam protrudes.

Title: Redn. of old vehicles to harmless prods.
Inventor: KISS GUENTER H
IPC: C10J3/08
Filed: 1990-02-23
Abstract: Household and domestic waste of mixed solutions, e.g. old cars, is reduced, if necessary after cutting and crushing, to a fraction of its original bulk, and packed under pressure into one or more containers to undergo low temp./pressure pyrolysis. With no intermediate stops, the waste then undergoes high temp.  pyrolysis.
