Abstract: A receiver for receiving a first usable frequency band and a second usable frequency band includes a band-pass filter device for filtering one or several receiving signals, a mixer device for converting the combination signal or the first band-pass filter signal and the second band-pass filter signal with a local oscillator signal, for obtaining a first intermediate frequency signal and a second intermediate frequency signal, and an intermediate frequency filter device for filtering the first intermediate frequency signal and the second intermediate frequency signal. Further, the receiver includes an analog/digital converter device for analog/digital converting the first filtered intermediate frequency signal and the second filtered intermediate frequency signal by using a single sampling frequency for obtaining a first digitized intermediate frequency signal and a second digitized intermediate frequency signal.

Abstract: A binder composition for injection moulding or extrusion of metallic or cmic powders in sintering technology comprised 30 to 90% by weight PVA with an average molecular weight of 35,000 to 1,000,000 and 10 to 70% by weight PEG with an average molecular weight of 500 to 50,000 as the melt softener and processing plasticizer. The PEG can be wholly or partly replaced by prepolymeric, aliphatic polyesters of adipic acid and PEG with an average molecular weight of 2,000 to 20,000 or by hydroxy-terminated copolymers of ethylene and propylene oxide with the same average molecular weight.
