    • 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. The electrocoating baths according to the invention are distinguished by the fact that the basic amine catalyst which catalyzes the reaction between the components (A) and (B) is neutralized, prior to further reaction of the intermediates formed from the components (A) and (B), with a Bronsted acid having a pK.sub.s value of the first stage of dissociation, measured at 20.degree. C., below 3.7, preferably below 3.5.

    • 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.
