Title: Microcrystalline hydrogen storage metal mixt. prodn. - by cold reductive pptn. from aq. salts used in alkaline storage batteries
Inventor: FABER PETER DR
IPC: H01M4/38
Filed: 1991-09-05
Abstract: In the prodn. of microcrystalline hydrogen-storage metal mixts. for electrode materials in alkaline storage batteries, the metals are produced as a mixt. or microcrystalline alloy by cold chemical redn. from their aq. salt solns., pref. by pptn. with alkali metal boranate at room temp. or alkali metal phosphite at 90 deg.C. The surface impurity-free pptd. metals are pref. filtered, dried and heat treated for 1-3 hrs. at 350-500 deg.C in H2 to combine the metals as a hydride. The metal mixt. is pref. based on Ni or Co, together with a second metal selected from gp. Vb and VIb metals (W, Mo, Cr, V, Nb, Ta), Re and U, and opt. a third metal such as Cu. The initial metal salt soln. may have a concn. of 1% to saturation and the reductant is pref. used as an aq. soln. of 1-20% concn. Filtration is pref. carried out under protective gas and drying is pref. carried out under protective gas (e.g. Ar or He) at 120 deg.C under vacuum at 60 deg.C. ADVANTAGE - The process is simpler than conventional high temp. melting processes and requires only a single post-treatment with hydrogen at about 400 deg.C to form the desired metal mixt. or alloy. The process is efficient and environment friendly and can be applied to metals not normally used in hydrogen storage alloys

Title: Process and apparatus for treating process waste waters of an ultrafiltration unit
Inventor: OBERDORFER-BOEGEL RAINER
IPC: B01D17/04
Filed: 1993-04-16
Abstract: The present invention relates to a process and an apparatus by which the process waste waters (effluents) of an ultrafiltration unit can be treated and purified. In order to decrease the special waste disposal of the known ultrafiltration units to a considerably lower proportion, the process waste waters arising at an ultrafiltration plant are fed via a collection line to a waste water purification plant. Precipitation of suspended matter initially takes place there in a storage vessel, before the suspended matter passes into one or more reaction vessels arranged at the outlet of the storage vessel, in which reaction vessel they are charged with a flocculant which chemically separates, breaks and binds the emulsions. The pollutants flocculated out of the process waste waters are then filtered out in dewatering containers (38) and disposed of and the pure water is returned back to the ultrafiltration unit. <IMAGE>

Title: Tube coupling for a spindle of a textile machine
Inventor: STAHLECKER GERD
IPC: D01H7/16
Filed: 1993-05-29
Abstract: A tube coupling for a spindle of a textile machine contains at least one take-up body which is arranged near the tube-receiving part of the spindle and which can be brought to bear against the inner wall of the tube. The take-up body is designed and arranged in such a way that it can be brought against the tube into a bearing position, in which a self-locking clamping connection between the tube-receiving part and the tube is made. This ensures that, even at low rotational speeds of the spindle, the tube is seated in a slip-resistant manner on the tube-receiving part. No high radial forces, which would impede the removal and attachment of the tube during the standstill of the spindle, need to be exerted on the take-off body.
