摘要:
The present invention relates to a process of multi-layer coating using a filler component comprisinga1) from 10 to 70% by weight of an aqueous dispersion of a water-dilutable polyurethane resin or of a plurality of water-dilutable polyurethane resins, the content of polyurethane in the aqueous dispersion being from 10 to 60% by weight, preferably from 20 to 50% by weight,a2) from 0 to 30% by weight of one or more amino resins and/or of a blocked polyisocyanate,a3) from 0 to 50% by weight of one or more physically drying binders which are different from a1),a4) from 5 to 40% by weight of one or more fillers and/or extenders,a5) from 0 to 30% by weight of color pigments and/or effect pigments,a6) from 0 to 5% by weight of one or more rheological auxiliaries and/or paint auxiliaries, anda7) from 0 to 10% by weight of organic solvent.The filler component is used to modify an aqueous basecoat composition, which is applied and followed by application of an aqueous basecoat second layer, a clear coat third layer, and then curing the coating layers together.

Device (1) for drying hair, comprising a hand-held unit (2) which is adapted to emit or discharge a flow of air to be directed onto the hair, characterized in that the hand-held unit (2) has a power source (18) which is arranged in a path (13) of the air flow to be emitted or discharged from the unit (2). In this way, heat or thermal energy that is generated in the power source (18) can be recovered or retrieved and transferred directly to the air flow in the device (1) so as to collect or scavenge waste heat from the power source.

A device for collecting and cooling reactor-meltdown products from a reactor pressure vessel includes an antechamber disposed below the reactor pressure vessel and an expansion chamber for the reactor-meltdown products. A channel which is disposed between the antechamber and the expansion chamber has a partition being destructible by the reactor-meltdown products. A closure element which connects a coolant reservoir to the expansion chamber is destructible by the reactor-meltdown products. A method for collecting and cooling reactor-meltdown products from a reactor pressure vessel includes collecting reactor-meltdown products in an antechamber disposed below the reactor pressure vessel and keeping them in the antechamber for a predetermined time interval. A partition disposed between the antechamber and an expansion chamber is destroyed with the reactor-meltdown products. The reactor-meltdown products penetrate from the antechamber into the expansion chamber and are spread in the expansion chamber. A closure element is destroyed with the reactor-meltdown products in the expansion chamber, for connecting a coolant reservoir to the expansion chamber and permitting coolant to flow into the expansion chamber where it cools the reactor-meltdown products.

Disclosed is a filler paste comprising polyurethane resin, chlorinated polyolefin, filler and/or extender, and organic solvents. The filler paste may also include physically drying binders, pigments, and/or rheological additives. Also disclosed is a basecoat containing the filler paste. The basecoat containing the filler paste may be applied directly to polyolefin substrates. After a flash-off period, a basecoat that does not contain the filler paste may be applied on top of the first basecoat layer. After a flash-off period for the second basecoat layer, a clearcoat may be applied and subsequently the applied layers may be cured together, with heating.

A nuclear reactor installation includes a reactor pressure vessel and a reactor core in the reactor pressure vessel. A supporting and protective structure supporting the reactor pressure vessel and surrounding the reactor pressure vessel on the bottom and laterally, has a bottom region and a circumferential wall. A core catcher device for the reactor core has a collecting basin for a core melt being installed below the reactor pressure vessel. The collecting basin has a bottom wall and a jacket wall being respectively separated from the bottom region and the circumferential wall of the supporting and protective structure by a spacing gap. Cooling channels are disposed in the spacing gap at the bottom wall and the jacket wall for exterior cooling of the collecting basin with a cooling liquid. Turbulence bodies are disposed in a surface region of the bottom wall for generating a turbulent flow of the cooling liquid flowing from the inside to the outside over the bottom wall toward the jacket wall. There is also a method for starting and maintaining exterior cooling of a core catcher device of a nuclear reactor installation.
