Abstract: A process for rectificatively separating at least one (meth)acrylic monomer-containing fluid by feeding the fluid into a rectification column containing at least one sieve tray without a runoff segment, wherein an elementary cell is obtained from a number of centers of passages in a sieve tray, and the cell shifts regularly and repeatedly along its edges, the lengths of two shifting vectors being the lengths of the edges of the cell along which the shifting is effected; an arrangement of the centers is such that the positions of an ideal center and a real center are separated by ?1% of half of the sum of the lengths of the two shifting vectors; and an arrangement of the passages is such that the sum of non-overlapping surface areas of an ideal passage with a real passage and vice versa is ?1% of the surface area of the ideal passage.

Abstract: The invention relates to a flat element comprised of a substrate and of at least one coating that covers the substrate. Both the substrate and the surface are darkly imbued in the visible spectral range. In the near infrared range, this assembly has a high degree of reflection in order to, despite the dark imbuement in the visible spectral range, reduce the heating caused by sunlight.
Abstract: A coating composition is prepared by polymerizing an addition polymer with a Tg of at least about 60° C. in the presence of a particulate pigment having substantially primary aggregate particles to form encapsulated pigment particles, isolating and drying the encapsulated pigment product, and combining the dried encapsulated pigment product with a coating vehicle.
Abstract: The present invention provides methods of drying radiofrequency-activatable inkjet inks, methods for customizing the radiofrequency parameters of an RF source based on pre-selected printing conditions, and methods for selecting or formulating an RF inkjet ink composition based on pre-selected printing conditions and/or printing equipment. The invention further provides radiofrequency-activatable inks having customized radiofrequency susceptibility profiles and to sets of such radiofrequency-activatable inks.

Abstract: High-functionality highly or hyper-branched polycarbonates based on dialkyl or diaryl carbonates and on aliphatic diol or polyols, processes for preparing them, and their use for preparing printing inks.
Abstract: A catalyst composition is applied to an interior of a hollow substrate. The composition is coated on the substrate by immersing the substrate into a vessel containing a bath of coating slurry. A vacuum is then applied to the partially immersed substrate. The intensity of the vacuum and its application time is sufficient to draw the coating slurry upwardly from the bath into each of a plurality of channels located in the interior of the hollow substrate. After removing the substrate from the bath, it is rotated 180°. A blast of pressurized air is applied at an intensity and for a time sufficient to distribute the coating slurry within the channels of the substrate to form a uniform coating profile therein.

Abstract: A substrate coated with a polymer system, wherein the polymer system reflects electromagnetic radiation (Bragg reflection), the wavelength of the reflection in the case of a strain produced by a mechanical stress is variable and the coated substrate as a whole has such little elasticity that, on elimination of the mechanical stress, the wavelength of the Bragg reflection is changed compared with the starting state.

Abstract: The invention relates to methods and compositions for analyzing plant acetohydroxy acid synthase large subunit (AHASL) genes. In particular, the invention relates to methods for the detection of wild-type AHASL alleles and mutant AHASL alleles that encode imidazolinone-tolerant AHASL proteins. The methods involve the use of PCR amplification and novel compositions comprising allele-specific and gene-specific primers to detect the presence of mutant and/or wild-type alleles present at the individual AHASL genes of a plant. Specifically, the methods and compositions are useful for analyzing the three AHASL genes of Triticum aestivum and the two AHASL genes of Triticum turgidum ssp. durum.
