Filed: 1989-03-13
Abstract: The invention relates to shears for cutting rolling stock, in particular cold shears for cutting off bars or sections to finished lengths, having top and bottom blades cutting the rolling stock at right angles and connected to one another via straps. Of the top and bottom blades, one is firmly connected to the straps and the other - moved via a crank mechanism - is guided rectilinearly on the straps parallel to the first blade. In order to create shears for cutting rolling stock during the rolling or straightening flow, the right-angle cut being retained, it is proposed that the crank mechanism driving the moving blade be designed as a two-throw crankshaft or double eccentric, a plunger which drives the blade being mounted on one crank radius, and the straps being mounted on the other crank radius offset by 180@. The straps are mounted at their other ends in the area of the fixed blade on a second crank mechanism with the same crank radius, and both crank mechanisms rotate in synchronism. <IMAGE>

Inventor: ELTERICH ANDREAS
IPC: G01S3/50
Filed: 1989-03-25
Abstract: The invention relates to a method for digitising and signal processing of received signals of a phased-array receiving system, which received signals are at the carrier frequency or intermediate frequency fm and in each case originate from an individual antenna or a sub-array of the phased-array receiving system, in the case of which method the received signals from the individual antennas or sub-arrays are subjected in the individual receiving channels to analogue band limiting in each case, subsequent analogue/digital conversion, and subsequent digital quadrature demodulation, and the demodulated signals are subjected to digital phase shifting, weighting and coherent addition in accordance with the desired spatial directions. The method is characterised in that the analogue/digital conversion is in each case carried out with oversampling at a first sampling frequency fS1 with 3 to 8, preferably 3 quantisation states, and in that the demodulated signals are subsequently subjected, in the two quadrature paths, to digital band limiting with undersampling at a second sampling frequency fS2.
