Patent DE-4131274-A1 (DE)
Inventor: DUETZMANN TILL DIPL CHEM DR
IPC: G21F1/10
Filed: 1991-09-20
Abstract: The invention relates to a plastic web of high-molecular neutron-moderating polymers with a neutron-absorbing additive containing boron. To obtain a plastic web which is as light as possible and absorbs biologically highly harmful neutrons with an energy in the range from 0.1 to 2 MeV, it is proposed that the plastic web contain first additives with high contents of neutron-scattering heavy metals like manganese, lead, tungsten or iron, and preferably brownstone, and second additives with high contents of wide-band operative neutron absorbers like boron, gadolinium and manganese, and preferably boron carbide, gadolinium oxide and brownstone. The recommended moderating polymer is high-molecular polyisobutylene with a Staudinger index in the range between 415 and 480 cm<3>/g. The neutron-absorbing effect of the plastic web of the invention is based on the combination of moderating, scattering and absorbent materials. The presence of neutron-scattering additives ensures that the trajectory of the scattered neutrons in the plastic web is substantially longer than the geometrical layer thickness so that the likelihood of striking an absorbent atomic nucleus is considerably increased.

Title: Two=part component with good binding and corrosion protection - comprises of coated metal part and 2nd part with resin coating joined under pressure both parts being heated to co:cure coatings
Inventor: MIESSEN HERMANN-JOSEF
IPC: C25D13/22
Filed: 1991-10-24
Abstract: A component comprises two or more parts, one of which is metallic. A corrosion resistant coating is applied to the metallic component and is initially left in an uncured condition. A resin is applied to the 2nd component and both parts are brought together under pressure for a final curing stage which polymerises both the corrosion coating and the resin bond between the components. USE/ADVANTAGE - Used to join two or more parts of a component requiring a good bond and corrosion protection e.g. brake pads to brake shoes, reduces process costs and uses less harmful chemicals. In an example, metallic brake shoe was degreased and treated with Zn phosphate to give a layer pref. less than 5 microns thick. The shoe was then cleaned with desalinated water and dried before an electrical dipping process. The cathodic dip coating was achieved at 26 deg.C. in a bath, for 2 mins. at 300V. The coating was based on an epoxy resin and was 25-80 microns thick. A final wash with desalinated water was concluded with air drying without curing the coating. The brake pad coated with a phenolic resin and both pad and coated metal component brought together under pressure. A combined curing of both the coating on the shoe and also the resin on the pad was realised by passage through an oven. The co-curing produced good corrosion protection of the metal shoe and also a strong bond between shoe and pad.

Title: Process and assembly to clean reverse osmosis membrane block - enhancing cleaning efficiency and reducing time required
Inventor: MAXEIN HANS-GEORG DIPL ING
IPC: B01D65/02
Filed: 1992-03-31
Abstract: A process to clean a membrane block which is part of a reverse osmosis unit separates a pressurised fluid into a concentrate and a permeate. The novelty is that: the concentrate is drained off at the beginning of the cleaning process; during a first phase of the cleaning process, a solvent is led to the membrane block, the permeate drained off and the volume flow of the drained concentrate is alternately reduced and increased; during a second phase, the solvent is led to the membrane block and the permeate is returned into the cleaning process; during a third phase, washing water is fed to the membrane block in place of solvent; and during a third phase, the permeate is returned into the cleaning process. USE/ADVANTAGE - The process facilitates the rinsing and cleaning of a membrane block in a reverse osmosis process. The process enhances the efficiency of the cleaning process and considerably reduces the time required.

Title: Corrosion protection coatings for metal surfaces - with primer layer, adhesion layer and thermoplastic covering layer applied as preheated powder coating to limit heat energy for sintering
Inventor: HUEBNER KNUT DIPL PHYS
IPC: B05D7/00
Filed: 1992-11-19
Abstract: Protective coverings to protect metal surfaces against corrosion, consist of a relatively thick thermoplastic layer, a thin adhesion promoting layer on the metal surface and a thin layer of adhesive between the two, at least the surface layer being applied by sintering, characterised in that in order to control the sintering energy, at least the powder for the surface layer is preheated.

It offers greater flexibility of operation than extrusion application processes together with improved adhesion of the coating which gives better corrosion resistance. Preheating of the coating powder allows the applied layer to be fully sintered without the necessity of heating the substrate to such high temps. that degradation of the coating compsn. would result or that the danger of self-ignition of the coating or of dust explosions would arise.
