A one-component polyurethane foam composition is described, which contains at least one prepolymer (isocyanate prepolymer), which has isocyanate groups, at least one blowing agent and known auxiliary and additive materials containing at least one ester, free of reactive hydrogens, of a polycarboxylic C2 to C7 acid and a monohydric C1 to C7 alcohol and/or a monocarboxylic C1 to C7 acid with a multi...

An object of the invention is a system for archives, especially for libraries, which make possible to clear up the items, like books, absent from shelf and the reason of the absence and which notifies exactly where to move a book under consideration if it is not in proper position. A basis of the invention is that an existing database (14) of a library contains data of all the books arranged alpha...

This invention is based upon the unexpected discovery that the surface of reclaimed rubber crumb particles can be devulcanized by heating the crumb particles to a temperature of at least about 150.degree.C under a pressure of at least about 3.4 x 10 6 Pascals in the presence of 2-butanol. It is further based upon the unexpected discovery that such surface devulcanized rubber crumb particles having...

The present invention relates to a method for performing radar measurement with a vehicle mounted radar system. Amplitude values of radar beams (107, 108) having different elevations and being reflected by objects (300) in front of the vehicle are measured. A vehicle pitch is then estimated based on relationships between these amplitude values, which pitch is compensated for when performing furthe...
