With the roll bender, a profile can be rolled and bent in two or three dimensions in one clamping. In addition, with the roll bender, the cross section or the wall thickness of a profile can be changed locally, whereby a new method for the production of load-adapted profiles is available. The roll b.....

The dualmode-radio uses two free space modes for the transmission of signals at the same frequency. The transmitter signal provides not only the useful signal but also an orthogonal signal for demodulation. This eleminates the need for the local oscillator in the reciever, which means significant sa.....
