Abstract: Polyamines based on derivatives of 1,3-bissubstituted 2-propanol containing a multiplicity of amino groups, the latter containing at least one primary amino group and additionally further N-basic groupings, prepared by reacting 1,2,3-trisubstituted propane compounds with bis(primary amines or with monoamines and bis(primary amines).The polyamines according to the invention are clear to yellowish or yellow products which, at room temperature, form viscous to highly viscous liquids or may be paste-like or wax-like. They may be used, inter alia, advantageously as starting products for the preparation of thermosetting, in particular water-dispersible and cataphoretically depositable binders based on aminourethanes for coating solid substrates, in particular metals.

Abstract: Curing component (A) based on polyisocyanates for binders (B) which contain groups containing active hydrogen, wherein the curing component (A) is a product of the reaction of (a1) polyisocyanates with (a2) .alpha.-hydroxyalkylpyridines.Mixtures of (A) and (B), and also, if appropriate, diluents (C) and additives (D), are stable on storage and give, even at temperatures of 120.degree.-140.degree. C., curing products which are sufficiently solvent-stable. They are suitable, in particular, for surface-coating preparations.

Abstract: The invention relates to aminourethanes essentially composed of structural units derived from (.alpha.) polyamines of the general formula (I) ##STR1## and of structural units derived from (.beta.) oligomeric or polymeric compounds which contain at least one terminal 2-oxo-1,3-dioxolane group.The invention further relates to a process for preparing these aminourethanes and to their use in particular in paint formulations.The aminourethanes according to the invention are suitable in particular for use as curable water-dispersible binders in particular for cationic electrocoating.

Abstract: Aminourethanes, a process for their preparation and their useThe invention relates to aminourethanes composed essentially of structural units derived from(A) polyamines of the general formula (I) an/or (II ##STR1## (B) if appropriate, further polyamines, (C) compounds containing, on average, at least one terminal 2-oxo-1,3-dioxolane group per molecule and(D) if appropriate, compounds having a monofunctional reaction, as chain stoppers.The invention also relates to a process for the preparation of these aminourethanes and to their use, in particular in paint formulations and especially in electrodeposition paints.

Abstract: A method and device is disclosed for increasing the hit probability of guided missiles exposed to jamming by double or multiple targets. In particular, the missiles are guided by the proportional navigation principle and have a follow-up target-seeking head. With the addition of a plurality of tracking filters, means for performing data analysis and means for performing data control to a conventional missile guidance system, signals from the target-seeking head or the missile may be analyzed to provide recognition of double or multiple target situations. Once recognition of the double or multiple target situation is made, the flow of data for controlling the guidance and target-seeking head follow is corrected to keep the missile permanently on the target.
