Patent DE-4038174-A1 (DE)
Title: Transfer of negative current to wires during galvanising - by passing wire over contact roller running slightly faster than wire, producing self=cleaning action with reduced wire tension
Inventor: POETTER ROBERT
IPC: C25D7/06
Filed: 1990-11-30
Abstract: In a wire galvanising process, transfer of the negative current onto the wire is achieved by contact rollers over which the wire passes. The contact rollers have the same circumferential speed as the passing wire and are subjected to corrosion, which requires frequent removal. Transfer of current from roller to wire is ensured by a relatively large wrap-round angle which increases wire tension. In the new process the rollers run at slightly higher circumferential speeds, approx 1.01-1.05 times greater than the linear wire speed and produce a self-cleaning action. The wrap-round angle of the wire is correspondinly reduced which lessens the tension in the wire. USE/ADVANTAGE - The process is used to galvanise wire, prevents corrosion of the cathodic roller and reduces frictional forces on the roller.

Patent DE-4042223-A1 (DE)
Inventor: MENGES WILHELM DIPL ING
IPC: C02F3/28
Filed: 1990-12-29
Abstract: In known reactors, for example of the UASB type, solids-containing waste waters, in particular polluted with settling materials, lead to failure of continuous operation. The novel reactor is to permit a novel process for integrated mechanical and anaerobic biological purification. In the reactor according to the invention, a separating device is therefore provided between the feed and overflow, which separating device can be passed by the waste water in both directions, but is essentially impassable to settling material. The process according to the invention comprises inflow of the solids-containing waste water, sedimentation of the settling materials in the reactor, and also the anaerobic biological purification of the waste water, all substances being able to be circulated and being able to be re-used in parent processes.

Title: Support surface for bars of soap - comprises transparent impermeable layer attached to one side of soap, allowing it to dry out quickly after use
Inventor: NOTTER HEINZ JOACHIM DIPL ING
IPC: C11D17/04
Filed: 1991-02-07
Abstract: Bars of soap are provided on one of their sides with a surface layer (A) which is impermeable to water. This layer is attached to the soap directly or by means of a connecting medium. It entirely covers a surface on which the soap can rest and extends upwards to an area of greater curvtaure (E). The edge (C) of the impermeable layer provides a smooth transition to the surface of the soap. USE/ADVANTAGE - Used in the mfr. or use of soap in bar form.

Patent DE-4130868-A1 (DE)
Inventor: BINDER WOLFRAM DR
IPC: A23K1/16
Filed: 1991-09-17
Abstract: 2.1. Fermentative preparation of amino acids for animal feed supplement purposes is a complex process, since the amino acid is present in the fermentation broth at only a few percent. Drying the crude fermentation broth and using it as such generally led to aggregating sticky products or to products having too low a supplementary amino acid content. Using the new animal feed supplement and preparation process, a supplementary amino acid is intended to be made available which is not too expensive, not excessively hygroscopic or sticky, and whose contents can be standardised. 2.2. The animal feed supplement is based on a fermentation broth and contains the majority of its components, if required, with the exception of part of the biomass. Preferably, the biomass is present at no more than 10 % by weight of the dry matter. Proteins are preferably present at up to a maximum of 10 % by weight. For the production, during fermentation, at least towards the end, the sugar content is adjusted to a value of at most 4 g/l and during further processing, if required, at least a part of the biomass is separated off. 2.3. Supplementation or preparation of animal feed agents or premixes, in particular containing lysine.
