Abstract: A process for producing polyacrylate particles by way of suspension polymerization and subsequent agglomeration can be performed. It was based on the problem of specifying a process for producing polyacrylate particles having defined shape and size, which enables improved heat management and requires a minimum amount of organic substances. Mechanical operating steps for establishing the shape and size of the particles—especially grinding and sieving—are to be avoided in order to produce a minimum amount of undersize. Finally, it is possible to implement the process economically on an industrial scale. An essential aspect of the process is that the steps of polymerization and agglomeration are conducted in separate apparatuses, namely suspension polymerization in a continuously operated capillary reactor and agglomeration in a batchwise reactor. The use of microstructured apparatuses is also possible.

Abstract: In a linkage device for flap rudders for watercraft, in particular ships, a first bearing housing includes a sliding piston and a first sliding bearing, and a second bearing housing includes a linkage pin and optionally a second sliding bearing. The first and the second bearing housings and/or the sliding piston and the linkage pin and/or optionally the first and the second bearings each have substantially the same diameter and/or substantially the same width and height.

Abstract: An upper rudder carrier bearing for a ship which has a bearing housing formed of a housing base body and a housing cover. An axial and a radial bearing are disposed in the bearing housing, which are both configured as plain bearings. The axial and/or the radial bearing is configured as a self-lubricating bearing.

Abstract: The invention relates to a process for aftertreating carbon black, wherein the carbon black is subjected to a carrier gas flow in a fluidized bed apparatus in the lower region of the apparatus, an additional gas stream is introduced into the fluidized bed apparatus, and the carbon black is aftertreated in the fluidized bed which arises.

Abstract: Process for the phase transformation of substances and mixtures of substances, in which the substance or the mixture of substances is introduced into a plasma reactor, the substance or the mixture of substances is converted into the higher-energy phase and the product is removed in gaseous form from the plasma reactor. The process can be used for the sublimation of metal salts, metal nitrates and/or metal alkoxides and other vaporizable metal-organic compounds.

Abstract: A dispersion of a hydrophobic silicic acid in water is delivered by means of the dispersion being conveyed onwards by means of a squeezing motion.

Abstract: Process of producing a composite thread in which at least one multifilament thread is run freely and substantially perpendicularly onto a core thread being drawn through a false-twist interval, such that the multifilament thread forms a sheath of at least partially separated filaments wrapped around the core thread, at least one of the core and sheath threads being heat-fixed or heat-set while in a twisted state. The product of the invention is a composite thread exhibiting the properties of natural fibers, especially wool-like properties, with relatively large variations in texture and crimping characteristics. The apparatus of the invention includes, in addition to conventional false-twist means for the core thread, a delivery means to supply at least one additional multifilament thread in a free path substantially perpendicularly onto the core thread in its false-twist interval.
