Abstract: Linear vibratory conveyor including a utility weight and a counterweight that can be vibratingly moved in opposing directions via a drive unit, the utility weight and the counterweight being connected via a non-rigid connector that represents or includes a vibration amplifying means for the vibration produced by the drive unit.

Abstract: Vibratory linear conveyor that includes a utility weight and a counterweight that can be vibratingly moved in opposing directions via a drive unit, the drive unit being coupled to the utility weight and to the counterweight and being arranged in a receiving chamber beneath the utility weight, whereby a first drive unit including an electromagnet and a second drive unit including a piezo-electric actuator can be exchangeably installed for drive units, identical types of fastening arrangements being provided and positioned identically on each drive unit for connecting to the fastening arrangement arranged on the utility weight and on the counterweight.

Abstract: In a method for bit detection at the receiver end of differentially coded binary or quaternary PSK signals in differential-coherent demodulation, first received, processed signals (Y.sub.n) are supplied parallel to L symbol detectors (S1 to SL) of the order j (j=1,2,3, . . . , L; (L>1)). Then the conjugate complex signals (Y*.sub.n-1, Y*.sub.n-2, . . . Y*.sub.n-L), which are delayed by j symbol periods, and the unchanged, processed input signals (Y.sub.n) are multiplied in multiplication elements (M) to non-quantized output values z.sub.n.sup.(j) of the L symbol detectors and are subsequently complex conjugated. Thereafter, already detected, regenerated PSK symbols (a.sub.n-1, a.sub.n-2, . . . a.sub.n-L+1), delayed by time delay elements (T), are correspondingly fed back, and from this a symbol (a.sub.n) is determined, for which the sum of the squared distances .vertline.z.sub.n.sup.(j) -.epsilon.a.sub.n a.sub.n-1 a.sub.n-2. . . a.sub.n-j+1 .vertline..sup.2 with j=2,3, . . .
