Inventor: PENTH ELFIE
IPC: B01D17/04
Filed: 1990-02-08
Abstract: Oil-in-water emulsion to be broken down in prepn. for legally acceptable discharge into the drainage system is  electrically coagulated by an electrode operating at 12V D.C.  with the emulsion pumped through. The electrode material has a woven carbon fibre layer acting as cathode, then intermediate non-conductive and final carbon-fibre layers where small oil  droplets coagulate into larger drops detached by the flowing liq.

Title: Vat dyestuff redn. to leuco form - involves using slow then fast reducing agent to prevent local high concn. of leuco form and give more level dyeing
Inventor: MANGOLD JOCHEN
IPC: D06P1/22
Filed: 1990-03-03
Abstract: Controlled prodn. of the leuco form (IA) of vat dyestuffs (I) by redn involves treating (I) first with a slow-acting reducing agent (II) and then with a fast-reacting reducing agent (III) in the presence of the substrate to be dyed. (II) has a potential of max. -800+/- 50 mV at pH 12-14 and pref. is (IIA). (III) has a potential of max. -950 +/- 50 mV at pH 12-14 and pref. is alkali dithionite. Vatting with (II) is carried out at 50-90 deg.C (II) being added gradually over a 15-30 min. period. (III) is added gradually at 50-90 deg.C until the potential is constant at max. 950 +/- 50 mV. USE/ADVANTAGE - Use of the (II)/(III) combination prevents local high concns. of (IA), making dyeing more level than usual. Pollution is reduced since much of the dithionite can be replaced by hydroxyacetone (IIA), which is more environmentally safe. In an example, 700g bleached cotton were heated from 40-60 deg.C in 10 min. at a goods/liquor ratio of 1:12 with 0.8% of the dyestuff C.I. 69525 in the presence of 2g dispersant (Na polyacrylate) and a chelating agent (0.5g EDTA).

Title: Coke dry cooling system with heat recovery - has closed cooling chamber and two steam drums operating at different pressures and giving improved cooling
Inventor: DUNGS HORST
IPC: C10B39/02
Filed: 1990-04-05

Title: Water electrolysis process control - by regulating prod. gas pressures to identical constant values
Inventor: SEEHUBER MICHAEL DIPL ING
IPC: C25B15/02
Filed: 1990-06-29
Abstract: Control of a water electrolysis system is effected by regulating the prod. gas pressure at both prod. sides (H2,O2) to the same constant value by means of measurements of the liq. level and/or pressures in the entrained electrolyte sepn. devices.

Abstract: Described is a torsional-vibration damper for piston engines, in particular for those in motor vehicles, which is mounted on the crank shaft of the engine so that it is torsionally rigid. Fitted to a collar (2) so that it concentrically surrounds the collar (2) is a first inertia ring (3) which is connected to the outer surface of the collar (2) by a rubber shock-absorbing element (5) acting in the peripheral direction. The damper also includes a second inertia ring (4) connected to the collar (2) by a rubber shock-absorbing element (8) also acting in the peripheral direction. In order that a simply designed damper of this kind of inertia ring will damp out all the vibrations produced by the engine, the rubber shock-absorbing element (5) holding the first inertia ring (3) is relatively rigid, while the rubber shock-absorbing element (8) holding the second inertia ring (4), which is located radially outside the first inertia ring (3), is relatively flexible. The outer inertia ring (4), which has a greater moment of inertia than the inner inertia ring (3), can be coupled in parallel to or in series with the inner inertia ring.
