摘要:
In order to ensure that upon destruction of a brittle article, in particular such as a ceramics element in the form of a frame receiving an apparatus, if possible no free fragments at all become detached therefrom, according to the invention the frame itself or a plate that is integrally moulded therewith and extends over the frame opening remote from view behind the apparatus is non-positively or positively connected at discrete points or in continuous segments in different regions to a connecting part injection-moulded from tough-elastic material. In turn, the connecting part can simultaneously be configured for detachably fastening the ceramics element to the apparatus or to an alternative construction part.

An adjustment device for a carrier plate which can be pivoted about two mutually orthogonal axes and is configured to receive a motor vehicle mirror, includes one motor per axis for moving a non-rotatably and non-tiltably guided linear drive, which is in engagement via a socket with a joint ball on the carrier plate, and a funnel-shaped hub provided with a hollow shaft. A hollow spherical segment of the funnel-shaped hub engages, by spring tabs, in a depression in the form of a hollow spherical segment in the carrier plate, and a spherical segment of the carrier plate is axially elastically clamped in a hollow spherical segment of a housing for drive trains of the two linear drives, thereby locking the hollow shaft on the housing.

Using integrated multi-component assembly injection molding, a two-part magnetic rotational angle sensor system having high sensing accuracy is very efficiently integrally produced in a tool as a functional unit that can be directly applied, comprising a polymer-bonded permanent magnet as a passive transmitter part in the first section, which can be rotated relative to the material of the active sensor receiver part, which material is sprayed thereon and then shrunk, with the potted receiver. For this purpose, injection molding materials are used that are mutually incompatible for adhesion and lift off from one another over the mutual contact regions due to shrinkage.

The invention relates to water-thinnable baking paints, the use thereof as filler material and intermediate stone chip resistant coat as well as a process for painting motor vehicle bodies.The water-thinnable baking paints comprise as binders a combination of(I) 20 to 70% by weight of a water-thinnable polyurethane resin with an acid value of 15 to 35,(II) 20 to 70% by weight of an epoxy resin-modified water-thinnable polyester which can be prepared by reacting a polyester (A) with a molecular weight (number average) below 2000, an acid value of 35-240 and a hydroxyl value of 56-320, with 0.3 to 1.5 equivalents per polyester molecule of an epoxy resin (B) having an epoxide equivalent weight of 170 to 1000, based on a bisphenol, and/or with a derivative of this epoxy resin (C) containing at least one epoxide group per molecule under reaction conditions where essentially only carboxyl groups react with epoxide groups, and(III) 0 to 20% by weight of a water-thinnable aminoplast resin, the sum of the components (I) to (III) being always 100% by weight.
摘要:
A paint sludge is subjected to aerobic biodegradation with increased dry content of the resulting sludge and the latter is then subjected to anaerobic biological degradation. The effluent from the two biostages are sterilized by ozonization, UV-irradiation or peroxide addition. The sludge from the anaerobic biostage can be dried to an inert granulate and drying vapors are recycled to the aerobic biostage. The sterile liquid is returned to the wash water circulation of the painting plant.
