The invention concerns windmills with rotating wings, whose generator is a synchronous generator which has a specially configured rotor and can be connected to the mains without an intermediate frequency converter. By providing the rotor with a multiple-phase winding which draws its current from a multiple-phase frequency converter, one can make the pole field move across the surface at a speed de...

An isocyanate-reactive composition containing a blowing agent that is generally a gas at ambient temperature and pressure which is storage stable is produced by including a phenol or alkylphenol having at least one phenolic hydroxyl group in the isocyanate-reactive composition in an amount sufficient to promote the solubility of the blowing agent. The isocyanate-reactive composition may be stored ...

A composite material is described which comprises at least two layers of different plastics materials which are directly bonded to each other, wherein A) one layer of the composite comprises polyurethane, and B) a layer of the composite which is directly bonded to layer A) comprises a thermoplastic plastics material which is different from the material which layer A) comprises, wherein layer A) co...

The present invention relates to composite materials made of at least one composite layer of a polyurethane and of a second composite layer which is directly bonded to the first layer and which consists of a thermoplastic material that is different from the polyurethane of layer A). The polyurethane material of layer A) is characterized by a residual content of free reaction components containing ...

The invention relates to a process for the preparation of vinyl pyrimidines of the formula I(see formula I) wherein R1 is hydrogen or a carboxylic ester group, and R2 is hydrogen or a group of the formula (a)(see formula a) wherein R a is hydrogen, a protecting group or a group easily hydrolyzable under physiological conditions, by reacting a compound of the formula II(see formula II) wherein R21 ...

The weighting of transmission paths (U) of a communications network KN in which information is transmitted at different data rates is carried out in accordance with a weighting rule whose weighting work has an essentially linear dependence on the capacity MaxCR of the respective transmission path U. The weighting work thus remains limited even for transmission paths U with a high capacity MaxCR.

A hinge arrangement for vehicle hoods in vehicles is described. The arrangement is intended to decrease injuries to pedestrians struck by the front of the vehicle. The hood is pivotable about at least two hinges, preferably applied at the rear of the hood. The hood is able to compliantly receive impacts in the vertical direction. Each respective hinge is fixed in at least two rods connected to the...

A new DTX-MAC protocol is proposed for a cellular radio telecommunications system with many users. Several users are allowed to transmit packets within a time-slotted frame structure. Direct sequence spread spectrum technique is used to spread the packets, and all packets within the frame are spread using the same spreading sequence. The packets overlap, but each packet begins within a distinct sl...

A method for use by a multi-mode, dual band mobile terminal (10) for identifying a presence of a GSM1900 carrier that is channelized into first channels having a bandwidth of 200kHz, and for distinguishing the GSM1900 carrier from at least a TDMA1900 carrier that is channelized into second channels having a bandwidth of 30kHz. The method includes steps of (a) tuning a receiver (16) to a frequency ...

A solid electrolyte battery having improved energy density and safety, the solid electrolyte battery incorporating a positive electrode; a negative electrode disposed opposite to the positive electrode; a separator disposed between the positive electrode and the negative electrode; and solid electrolytes each of which is disposed between the positive electrode and the separator and between the sep...

A method for a binder-free manufacturing a nanostructured porous film, e.g. for use in solar cells, comprises the steps of: preparing a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent (21), depositing the particle suspension on a conducting substrate, removing the suspending agent by evaporation (31), and compressing (P) the deposited particles for mechanical...
