Abstract: Pseudoplastic curable mixtures comprising (A) at least one reaction product of (a1) at least one reaction product of (a11) at least one olefinically unsaturated carboxylic acid with (a12) at least one glycidyl ester of an unsaturated carboxylic acid (a121) with (a2) at least one polyisocyanate having an epoxide group (calculated as M=42 daltons) content <0.2% by weight and an acid number <10 mg KOH/g and also (B) at least one rheology control additive, process for preparing them, and their use.

Abstract: Electroceramic component having a component body (10), connection metallization coatings (2, 3) and also a protective encapsulation (15 to 18) made of two different materials on in each case two mutually opposite areas of the component body (10) which are free from the connection metallization coatings (2, 3).

Abstract: The invention relates to aqueous electrocoating baths for cathodic paint deposition which contain, as cathodically depositable binders, modified epoxide-amine adducts and are prepared by reacting, in the presence of basic amine catalysts,(1)(A) polyepoxides with(B) compounds which contain, per molecule, one or more, preferably 2, hydroxyl groups bonded to aromatic and/or (cyclo)aliphatic molecular fragments, to form epoxide group-containing intermediates, and(2) by subsequently reacting these intermediates, if appropriate, with further conventional modifiers and finally with(C) primary and/or secondary (poly)amines or their salts and/or salts of tertiary amines, the resultant reaction products being neutralized with acids, if appropriate, dispersed in an aqueous medium and these dispersions further processed by well-known methods to form electrocoating baths.

Abstract: A security bar rack for installation in the inlets or outlets of water-treatment plants or power stations comprises a number of hollow tubes. A conductive indicator element with uninsulated external surfaces is stretched within each tube and extends over its entire length. Each indicator element is provided with a separate monitoring circuit which actuates a signal element in a way that a detectable alarm signal is emitted if any change takes place in the dielectric condition of the indicator element/tube assembly. In addition a second signal element is provided which is controlled by the monitoring circuit so as to produce a detectable signal to indicate that the device is in a state of readiness to produce an alarm signal.

Abstract: Electric resistor, including a PTC body being formed of ceramic material and having opposite poles, two opposite outer side surfaces being parallel to the longitudinal axis of the PTC body and two opposite end faces perpendicular to the outer side surfaces, the PTC body having rows of mutually parallel depressions formed in the end faces defining inner surfaces and leaving partitions therebetween, metal coatings disposed on the inner surfaces at the opposite poles and partitions, metal layers disposed on the outer side surfaces, and metal strips being disposed on the end faces interleaved in comb-fashion and being connected to the metal layers, defining current flow paths from the metal layers and metal strips through the partitions being perpendicular to the longitudinal axes of the depressions and electrically connecting the pole coatings of a respective row of depressions to each other, and a method for the manufacture thereof.
