Abstract: The present invention relates to novel aspartates, their method of production and the use of these aspartates as reactive components for polyisocyanates in two-component polyurethane coating compositions and for preparing polyurethane prepolymers. The aspartaes are prepared by first reacting a di- or polyamine with an unsaturated ester and then reacting the resultant product with a ketone.

Abstract: An assembly is provided having two opposing parallel guides and a panel having two opposite parallel lateral edges cooperating with said guides for a frictional sliding movement of the panel relative to the guides. The edges of the panel are resiliently curved such that there are defined three contact points between each edge and corresponding guide. In one embodiment, two contact points are near the ends of each edge and there is an intermediate contact point. The assembly may be provided in an open roof assembly for a vehicle.

Abstract: A reactor for use in electrochemical processing of a microelectronic workpiece is set forth and described herein. The apparatus comprises one or more walls defining a processing space therebetween for containing a processing fluid The processing space includes at least a first fluid flow region and a second fluid flow region A first electrode is disposed in the processing fluid of the first fluid flow region while a second electrode, comprising at least a portion of the microelectronic workpiece, is disposed in the processing fluid of the second fluid flow region.

Abstract: A reactor for use in electrochemical processing of a microelectronic workpiece is set forth and described herein. The apparatus comprises one or more walls defining a processing space therebetween for containing a processing fluid. The processing space includes at least a first fluid flow region and a second fluid flow region. A first electrode is disposed in the processing fluid of the first fluid flow region while a second electrode, comprising at least a portion of the microelectronic workpiece, is disposed in the processing fluid of the second fluid flow region. Fluid flow within the first fluid flow region is generally directed toward the first electrode and away from the second electrode while fluid flow within the second fluid flow region is generally directed toward the second electrode and away from the first electrode.

Abstract: The present invention relates to ethylenically unsaturated polyurethanes whichi) are substantially free from isocyanate groups,ii) are liquid at 25.degree. C.,iii) have a total content of ethylenically unsaturated groups (calculated as C=C, MW 24) of 1 to 20% by weight andiv) contain the reaction product of 4-isocyanatomethyl-1,8-octamethylene diisocyanate (NTI) with a hydroxyalkyl (meth)acrylate.The present invention also relates to a one-component coating composition containing these ethylenically unsaturated polyurethanes.

Abstract: The present invention relates to aldimines corresponding to the formulaX.sub.1 --[N.dbd.CHCH(R.sub.1)(R.sub.2)].sub.2whereinX.sub.1 represents the group obtained by the removal of the amino groups from 2-methyl-1,5-pentane diamine,R.sub.1 and R.sub.2 may be the same or different and represent optionally substituted hydrocarbon radicals, or R.sub.1 and R.sub.2 together with the .beta.-carbon atom from a cycloaliphatic or heterocyclic ring.The present invention relates to a clear, solvent-containing coating composition which containsa) an isocyanurate group-containing polyisocyanate which contains less than 5% by weight, based on the weight of component a), of allophanate and uretdione groups andb) an aldimine corresponding to the formulaX.sub.1 --[N.dbd.CHCH(R.sub.1)(R.sub.2)].sub.nwherein X.sub.1, R.sub.1 and R.sub.
