A method of protecting a part of a surface of an aircraft against contamination with insect residues and/or against icing is described. The method includes the following steps: a) coating the part of the surface to be protected with a coating that can, within a period of ≦3 hours from take-off of the aircraft and in normal flying conditions, reduce the adhesion to the part of the surface to be protected until detachment occurs on the basis of (i) temperature change and/or (ii) UV radiation and/or (iii) addition of a decomposing component and/or (iv) difference in air humidity, and b) exposing the part of the surface to be protected to (i) a temperature change and/or (ii) UV irradiation (iii) and/or addition of a decomposing component and/or (iv) a difference in air humidity, so that the coating together with any contaminants and/or icing thereon detaches.

In a method for distributing packages or similar dispatched articles, packages that are to be transported from a private and/or commercial sender to an addressee are acquired in a collecting location. In this collecting location, the packages are provided with a package code that has electronically detectable data, and subsequently, the packages are distributed and/or delivered by means of transport vehicles. According to the invention, the collected packages are supplied to a HUB center that is connected to several collecting locations and in the HUB center the respective package codes are expanded with measurement data (length, width, height, weight) of the package to a package routing code. These package routing codes of all packages are supplied to a central computer and the packages are arranged in accordance with a route planning that can be dynamically optimized by the central computer into a sequence that is sorted in accordance with distribution zones. This package arrangement as well as the package routing codes are received by a vehicle in a distribution-compatible sorted arrangement and, subsequently, the packages are delivered by a controlled distribution in an automatically controllable way to the addressee.

摘要:
The invention concerns an adhesive composition for producing thermoset products, capable of being heated by means of an electric field, a magnetic field, an electromagnetic field or an alternating electromagnetic field, and containing filler particles which are metallic, ferromagnetic, ferrimagnetic, superparamagnetic or paramagnetic. Said adhesive composition can be hardened under the action of heat to form a high-resistance stable adhesive assembly, said resulting adhesive assemblies capable of being likewise dissociated under the action of heat.
摘要:
Method for production of nanocomposites from nanopowders present in agglomerated form and organic binders. Through surface modification of the nanofillers in an organic medium it is possible to divide the agglomerates permanently to such an extent that transparent nanocomposites can be preserved. The modified nanopowder is preferably isolated as a dry intermediate. The production of the disclosed nanocomposites is simpler than the production of nanocomposites by the sol-gel technique and in addition is more flexible and has wider applicability. An important application for the nanocomposites is scratch-resistant paints.
